Could The U.S. Government Shutdown Hammer Earth and Mars Missions?

As Day 2 of the United States government shutdown continues, some short-term effects are already in evidence when it comes to Earth and space.

Most of the NASA and National Oceanic and Atmospheric Administration (NOAA) websites are offline. Social media updates are silent. At NASA, 97% of agency employees are off work and media reports indicate that 55% of NOAA’s employees are furloughed.

If the shutdown lasts for very long, however, long-term programs could feel the pain. This includes a couple of Mars missions NASA is developing, as well as Earth-based climate research and satellite observation from NOAA.

Mars 2020

A twin rover to Mars Curiosity, called Mars 2020 for now, is expected to leave for the Red Planet in 2020 and do investigations into past life and habitability. Planning is still in the early stages, but an announcement of opportunity for science investigators was supposed to happen on Oct. 8. Notices of intent were due Oct. 15.

“The preproposal conference, scheduled for 10/8, may be rescheduled and the due date for NOIs (currently 10/15) could be delayed, if the government is still shut down closer to those dates,” NASA officials wrote in an update before the shutdown on Monday.

MAVEN

As widely reported yesterday, the next Mars orbiter from NASA is expected to lift off from Earth on Nov. 18. Now, however, preparatory work has ceased and there is some concern from team members that it will miss the launch window, which extends into December. At worst, this means MAVEN’s launch could be delayed until 2016, when the next opportunity opens.

“The hardware is being safed, meaning that it will be put into a known, stable, and safe state,” Bruce Jakosky, MAVEN’s principal investigator, told Universe Today‘s Ken Kremer yesterday. “We’ll turn back on when told that we can. We have some margin days built into our schedule.”

NOAA

As with NASA, NOAA is keeping up with mission-critical activities — which in their case, includes weather forecasting. Long-term climate research, however, is reportedly being shelved.

“For example, Harold Brooks, a top tornado researcher who works at the National Severe Storms Laboratory in Norman, Okla., reported his furlough notice on Facebook on Tuesday,” Climate Central wrote on Oct. 1. “Much of the staff at NOAA’s Earth Systems Research Lab and the Geophysical Fluid Dynamics Laboratory, except for positions related to maintaining computing resources, have also been furloughed. Those two labs are heavily involved in NOAA’s climate research programs.”

Observers are also worried that a lengthy shutdown could push back the time when new weather satellites become available. There have been multiple reports about a “weather satellite gap” coming in the United States as many of NOAA’s geostationary and polar-orbiting satellites are nearing the end of their expected lives. The Subcommittees on Oversight and Environment held hearings into this issue in September.

What’s still online?

These are some of the programs that are still happening at NASA and NOAA:

NASA:

Bare-bones management on programs such as the International Space Station and several robotic missions that are already in operation (such as the Lunar Atmosphere and Dust Environment Explorer (LADEE).
Certain missions are in critical phases that could be hurt if work stops, such as the James Webb Space Telescope, which is undergoing cryogenic testing on some of its instruments.
Several missions run out of the Jet Propulsion Laboratory and Applied Physics Laboratory are still running as usual, according to the Planetary Society, as these receive contract money from NASA; this means Mars Curiosity is still working, for example.
The Mars Reconnaissance Orbiter’s HiRISE camera is still snapping pictures, its Twitter account reported, which is positive given that it was intended to snap shots of Comet ISON during its closest approach to Mars yesterday.
The decades-long Landsat Earth observation program is still operating, according to The Atlantic, with data being sent back to Earth as usual. The difference is this information won’t be packaged as usual until government operations restart.

NOAA (all information according to this Department of Commerce document):

The Office of Oceanic and Atmospheric Research will keep 73 employees on board “to ensure continuity of crucial long-term historical climate records, and real-time regular research to support ongoing weather and air quality prediction services,” NOAA said.
184 employees will stay with the Environmental Satellite and Data Information Service for command and control of several satellites for NOAA and the Department of Defense.
474 employees will remain with the National Marine Fisheries Service. 174 are funded in another form besides appropriations. The others are a mix of law enforcement, fisheries management and property protection officials.
490 employees are with the Office of Marine and Aviation Operations for observational data collection related to weather forecasting.
173 employees are with the National Ocean Service. 17 are funded outside of appropriations, while the 156 remaining “are required to protect against imminent and significant threats to life and property by supporting safe maritime commerce in U.S. waters, including real-time water level data for ships entering U.S. ports, critical nautical chart updates, and accurate position information,” NOAA stated. Some are also monitoring marine health aspects such as algal blooms.
There are 19 IT-related employees and 20 employees providing support services.
The large bulk of employees still at work, 3,935 people, are with the National Weather Service to keep up weather forecasting.

There’s no word yet on when government employees could go back to work. Congress representatives are jousting over the implementation of a spending bill to keep the money flowing to government departments. One big issue: whether to include the Affordable Care Act, sometimes dubbed Obamacare, in the bill.

Another deadline is looming, too. Treasury Secretary Jack Lew has warned repeatedly that on Oct. 17, if the debt ceiling is not raised, the United States government may default on some financial obligations.

Government Shutdown Stops MAVEN Work; Threatens NASA Mars Launch!

KENNEDY SPACE CENTER, FL – The upcoming Nov. 18 blastoff of NASA’s next mission to Mars – the “breathtakingly beautiful” MAVEN orbiter – is threatened by today’s (Oct. 1) shutdown of the US Federal Government. And the team is very “concerned”, although not yet “panicked.”

MAVEN’s on time launch is endangered by the endless political infighting in Washington DC. And the bitter gridlock could cost taxpayers tens of millions of dollars or more on this mission alone!

Why? Because launch preparations at NASA’s Kennedy Space Center (KSC) have ceased today when workers were ordered to stay home, said the missions top scientist in an exclusive to Universe Today.

“MAVEN is shut down right now!” Prof. Bruce Jakosky, MAVEN’s principal Investigator, of the University of Colorado at Boulder, told Universe Today in an exclusive post shutdown update today.

“Which means that civil servants and work at government facilities [including KSC] have been undergoing an orderly shutdown,” Jakosky told me.

The nominal interplanetary launch window for NASA’s $650 Million MAVEN (Mars Atmosphere and Volatile EvolutioN Mission) mission to study the Red Planet’s upper atmosphere only extends about three weeks until Dec. 7.

If MAVEN misses the window of opportunity this year, liftoff atop the Atlas V rocket would have to be postponed until early 2016 because the Earth and Mars only align favorably for launches every 26 months.

Any launch delay could potentially add upwards of tens to hundreds of millions of dollars in unbudgeted costs to maintain the spacecraft and rocket – and that’s money that NASA absolutely does not have in these fiscally austere times.

MAVEN and much of NASA are not considered “essential” – despite having responsibility for hundreds of ongoing mission operations costing tens of billions of dollars that benefit society here on Earth. So about 97% of NASA employees were furloughed today.

What’s happening with the spacecraft right now?

“The hardware is being safed, meaning that it will be put into a known, stable, and safe state,” Jakosky elaborated.

Team members say there are about nine days of margin built into the processing schedule, which still includes fueling the spacecraft.

“We’ll turn back on when told that we can. We have some margin days built into our schedule,” Jakosky told me.

“We’re just inside of 7 weeks to launch, and every day is precious, so we’re certainly as anxious as possible to get back to work as quickly as possible.

And he said the team will do whatever necessary, including overtime, to launch MAVEN to the Red Planet by Dec. 7.

“The team is committed to getting to the launch pad at this opportunity, and is willing to work double shifts and seven days a week if necessary. That plus the existing margin gives us some flexibility. “

“That’s why I’m concerned but not yet panicked at this point.”

But a lengthy delay would by problematical.

“If we’re shut down for a week or more, the situation gets much more serious,” Jakosky stated.

Until today, all of the spacecraft and launch preparations had been in full swing and on target – since it arrived on Aug. 2 after a cross country flight from the Colorado assembly facility of prime contractor Lockheed Martin.

Indeed it was all smiles and thumbs up when I was privileged to personally inspect MAVEN inside the clean room at KSC a few days ago on Friday, Sept 27 during a media photo opportunity day held for fellow journalists.

Until now, “MAVEN was on schedule and under budget” said Jakosky in an interview as we stood a few feet from the nearly fully assembled spacecraft.

And in an ultra rare viewing opportunity, the solar panels were fully unfurled.

“The solar panels look exactly as they will be when MAVEN is flying in space and around Mars.”

“To be here with MAVEN is breathtaking,” Jakosky told me. “

“Its laid out in a way that was spectacular to see!”

If absolutely necessary it might be possible to extend the launch window a little bit beyond Dec. 7, but its uncertain and would require precise new calculations of fuel margins.

“The nominal 20-day launch period doesn’t take into account the fact that our actual mass is less than the maximum allowable mass,” Jakosky explained.

“The last day we can launch has some uncertainty, because it also requires enough fuel to get into orbit before our mission would begin to be degraded.”

It sure was breathtaking for me and all the media to stand beside America’s next Mission to Mars. And to contemplate it’s never before attempted science purpose.

“MAVENS’s goal is determining the composition of the ancient Martian atmosphere and when it was lost, where did all the water go and how and when was it lost,” said Jakosky.

That’s the key to understanding when and for how long Mars was much more Earth-like compared to today’s desiccated Red Planet.

Following a 10 month interplanetary voyage, MAVEN would fire thrusters and brake into Mars orbit in September 2014, joining NASA’s Red Planet armada comprising Curiosity, Opportunity, Mars Odyssey and Mars Reconnaissance Orbiter.

Lets all hope and pray for a short government shutdown – but the outlook is not promising at this time.

Stay tuned.

NASA’s intrepid Opportunity rover has begun an exciting new phase in her epic journey – the ascent of Solander Point, the first mountain she will ever climb, after roving the Red Planet for nearly a decade. See the rovers tilted look-back view in our Sol 3431 mosaic above.

Furthermore, ground breaking discoveries providing new clues in search of the chemical ingredients required to sustain life are sure to follow as the rover investigates intriguing stratographic deposits distributed amongst Solander’s hills layers.

Why ? Because NASA’s powerful Mars Reconnaissance Orbiter (MRO) circling overhead has also recently succeeded in collecting “really interesting” new high resolution survey scans of Solander Point! Read my prior pre-survey account – here.

So says Ray Arvidson, the mission’s deputy principal scientific investigator, in an exclusive Opportunity news update to Universe Today. The new MRO data are crucial for targeting the rover’s driving in coming months.

After gaining approval from NASA, engineers successfully aimed the CRISM mineral mapping spectrometer aboard MRO at Solander Point and captured reams of new high resolution measurements that will inform the scientists about the mineralogical make up of Solander.

“CRISM data were collected,” Arvidson told Universe Today.

“They show really interesting spectral features in the [Endeavour Crater] rim materials.”

Solander Point is an eroded ridge located along the western rim of huge Endeavour Crater where Opportunity is currently located.

“Opportunity is on the bench at the tip of Solander Point,” Ray Arvidson told Universe Today exclusively. Arvidson is the mission’s deputy principal scientific investigator from Washington University in St. Louis, Mo.

At the bench, the long lived rover has begun scaling Solander in search of science and life giving sun.

“The CRISM data are being discussed by the MER [Mars Exploration Rover] Team this week,” Arvidson told me.

And it will take some time to review and interpret the bountiful new spectral data and decide on a course of action.

“For the CRISM data analysis we will have the MER Team see the results and agree.”

Expect that analysis to take a “couple of weeks” said Arvidson.

The new CRISM survey from Mars orbit will vastly improve the spectral resolution – from 18 meters per pixel down to 5 meters per pixel.

Above is the Pancam panorama acquired on sol 3375 when Opportunity was still approaching Solander Point. On it I have plotted the subsequent drives along the east side of the point, and the location on the contact as of September 18. The approximate places where we need to be by later this fall are shown here for anyone following along. It's a new unexplored land with new scenes.

Another important point about ‘Solander Point’ is that it also offers northerly tilted slopes that will maximize the power generation during Opportunity’s upcoming 6th Martian winter.

In order to survive those Antarctic like, ‘bone chilling” winter temperatures on the Red Planet and continue with her epic mission, the engineers must drive the rover so that the solar wings are pointed favorably towards the sun.

And don’t forget that winter’s last six full months – that’s twice as long on Mars as compared to Earth.

The daily solar power output has been declining as Mars southern hemisphere enters late fall.

In the above Navcam panorama acquired on mid-morning on September 18 (sol 3431), you can see the contact between the younger Burns Formation sulfate-rich sands on the right and the older rocks of Endeavour crater on the left. We will probably follow this contact for ways to the south before starting the climb next week. Caption and Credit: NASA/JPL/Larry Crumpler

After traversing several months across the crater floor from the Cape York rim segment to Solander, Opportunity arrived at the foothills of Solander Point.

Solander and Cape York are part of a long chain of eroded segments of the crater wall of Endeavour crater which spans a humongous 14 miles (22 kilometers) wide.

Solander Point may harbor deposits of phyllosilicate clay minerals – which form in neutral pH water – in a thick layer of rock stacks indicative of a past Martian habitable zone.

The science team is looking at the new CRISM measurements, hunting for signatures of phyllosilicate clay minerals and other minerals and features of interest.

“Opportunity is on the bench on the northwest side of the tip of Solander Point,” Arvidson explained.

Since pulling up to Solander, the robot has spent over a month investigating the bench surrounding the mountain to put it the entire alien Martian terrain in context for a better understanding of Mars geologic history over billions of years.

Eons ago, Mars was far warmer and wetter and more hospitable to life.

“The rover is finishing up work on defining the stratigraphy, structure, and composition of the bench materials.”

“We are working our way counterclockwise on the bench to reach the steep slopes associated with the Noachian outcrops that are part of the Endeavour rim,” Arvidson elaborated.

“Opportunity is slightly tipped to the north to catch the sun.”

“Probably this week we will direct the rover to head south along the western boundary between the bench and the rim materials, keeping on northerly tilts,” Arvidson told me.

How does the bench at Solander compare to other areas investigated at Endeavour crater, I asked.

“The Solander Bench looks like the bench we saw around Cape York and around Sutherland Point and Nobbys Head,” replied Arvidson.

The rover recently investigated an outcrop target called ‘Poverty Bush’. She deployed her 3 foot long (1 meter) robotic arm and collected photos with the Microscopic Imager (MI) and collected several days of spectral measurements with the Alpha Particle X-ray Spectrometer (APXS).

Thereafter she resumed driving to the west/northwest around Solander.

“On September 13, Opportunity finally landed on the bed rock of Solander Point,” wrote Larry Crumpler, a science team member from the New Mexico Museum of Natural History & Science, in his latest field report about the MER mission.

“The terrain right here is awesome,” according to Crumpler.

“There are several geologic units that are overlapping here. And Opportunity is sitting on the contact.”

“On the east side of the contact are rocks maybe a billion years older than those on the west side of the contact. This sort of age progression is what geologists look for when trying to understand the past by reading the rocks.”

“Opportunity is allowing us for the first time to do not only fundamental geographic exploration, but it is enabling on the ground geologic study of past climatic history on Mars,” notes Crumpler.

Today marks Opportunity’s 3441st Sol or Martian Day roving Mars – for what was expected to be only a 90 Sol mission.

So far she has snapped over 184,500 amazing images on the first overland expedition across the Red Planet.

Her total odometry stands at over 23.82 miles (38.34 kilometers) since touchdown on Jan. 24, 2004 at Meridiani Planum.

Meanwhile on the opposite side of Mars, Opportunity’s younger sister rover Curiosity is trekking towards gigantic Mount Sharp and just discovered water altered pebbles at the intriguing ‘Darwin’ outcrop.

And NASA is in the final stages of processing of MAVEN, the agencies next orbiter, scheduled to blast off from Cape Canaveral on Nov.18 – see my upcoming up close article.

Watch a year of incredibly detailed work in building the MAVEN spacecraft — sped up to take just 10 minutes. It’s the dance known as ATLO: Assembly, Test, and Launch Operations, set to a jazzy beat. The next spacecraft to Mars, the Mars Atmosphere and Volatile EvolutioN or MAVEN began ATLO procedures a year ago on Sept. 11, 2012. It was shipped to Kennedy Space Center’s Payload Hazardous Servicing Facility on Aug. 2, 2013 to begin preparations for its scheduled launch on Nov. 18, 2013.

Find out more about MAVEN in one of our previous articles about preparations for the mission, or at NASA’s MAVEN website.

How to See Mars in September 2013: The Red Planet Pierces the Beehive & More

Mars on September 8th. (Created by the author using Stellarium).

Launch season for Mars missions is almost upon us once again.

This is a time when spacecraft can achieve an optimal trajectory to reach the Red Planet, expending a minimal amount of fuel and taking the shortest period of time. This window of opportunity, which opens once every two years, always opens up about six months prior to Martian opposition.

For you stargazers, this is also the best time to observe the Red Planet as it makes its closest approach to Earth. And no, it won’t appear as large as a Full Moon, but it will make for a fine telescopic target.

During the last launch window in 2011-12, Mars Curiosity made the journey, and Russia’s Phobos-Grunt tried. Hey, it’s a tough business, this spaceflight thing. This time around, The Indian Space Research Organization (ISRO) hopes to launch its first ever interplanetary spacecraft, with its Mars Orbiter Mission departing on October 18th. NASA is also sending its Mars Atmosphere Volatile EvolutioN mission known as MAVEN to study the atmosphere of the Red Planet.

Opposition next occurs on April 8th, 2014, but the start of launch season always finds Mars emerging high to the east at dawn. Starting next week, Mars has some interesting encounters that are worth checking out as a prelude to the upcoming opposition season.

The planet Mars shines at +1.6 magnitude and is about 4” in size in September. This is a far cry from its maximum size of 15.1” that it will achieve next spring, and its grandest maximum size of 25.1” that it reached in 2003. All oppositions of Mars are not created equal, because of the planet’s 9.3% eccentric orbit.

But the good news is, we’re trending towards a better series of oppositions, which follow a roughly 15 year cycle. In 2018, we’ll see an opposition nearly as good as the 2003 one, with Mars appearing 24.1” in size. This is also the time frame that Dennis Tito wants to launch his crewed Mars 2018 flyby.

But back to the present. The action starts on September 2^nd when the waning crescent Moon passes 6.1 degrees SSW of Mars.

Mars is currently in the constellation Cancer, and will actually transit (pass in front of) the open star cluster known as the Beehive or Messier 44, standing only 0.23 degrees from its center on September 8^th. M44 is 1.5 degrees in size, and this presents an outstanding photo-op.

The path of Mars through the beehive cluster from September 3rd through September 12th. (Created in Starry Night; Image courtesy of Starry Night Education).

At high power, you might just be able to catch the real time motion of Mars against the background stars of M44. Mars currently rises three hours before the Sun, giving you a slim window to accomplish this feat.

Mars is also in the midst of a series of transits of the Beehive Cluster, with one occurring every other year. Mars last crossed M44 on October 1^st, 2011. The next time you’ll be able to spy this same alignment won’t be until August 20^th, 2015.

But another cosmic interloper may photo-bomb Mars in September.

We’re talking about none other than Comet C/2012 S1 ISON, the big wildcard event of the season. Comet ISON is just peeking out from behind the Sun now, and dedicated amateurs have already managed to recover it. “IF” it follows projected light curve predictions, ISON may reach binocular visibility of greater than +10^th magnitude by October 1st and may breech naked eye visibility by early November.

ISON approaches within two degrees of Mars on September 27^th. Its closest apparent approach is will be on Oct 18th at a minimum separation of 0.89 degrees, just over the size of a Full Moon. How bright ISON will actually be at that point is the question of the season. To quote veteran comet hunter David Levy, “Comets are like cats. They have tails, and they do whatever they want.” The closest physical approach of Mars and Comet ISON is on October 1st at 0.07 astronomical units, or 10.4 million kilometres apart. Both will be crossing over from the astronomical constellations of Cancer into Leo in late September.

Comet ISON and Mars looking east on the morning of September 27th. (Created in Starry Night; Image courtesy of Starry Night Education).

Mars gets another close shave from a comet next year, when Comet C/2013 A1 Siding Spring passes 123,000 kilometres from Mars on October 19^th, 2014. Interestingly, MAVEN will be arriving just a month prior to this if it departs Earth at the start of its 21 day window. Engineers have noted that an increase in cometary dust may be a concern for the newly arrived spacecraft during insertion into Martian orbit.

MAVEN Principal Investigator Bruce Jakosky notes that the first concern is the safety of the spacecraft, the second is studies of Mars, and the third is, just perhaps, to carry out observations of the comet.

Look for more information on Universe Today about the Martian cometary flybys as each event gets closer.

September is a great time to begin observations of the Red Planet. Usually, 8” seconds in diameter is the threshold that is frequently quoted for the first surface features (usually to polar ice caps) to become apparent, but we’re already seeing astro-imagers getting detailed images of Mars, right now.

Be sure to follow Mars on its trek across the September dawn skies as robotic explorers prepare to embark on their epic journeys!

Are We Martians? Chemist’s New Claim Sparks Debate

Are Earthlings really Martians ?
Did life arise on Mars first and then journey on rocks to our planet and populate Earth billions of years ago? Earth and Mars are compared in size as they look today. NASA’s upcoming MAVEN Mars orbiter is aimed at answering key questions related to the habitability of Mars, its ancient atmosphere and where did all the water go.
Story updated[/caption]

Are Earthlings really Martians?

That’s the controversial theory proposed today (Aug. 29) by respected American chemist Professor Steven Benner during a presentation at the annual Goldschmidt Conference of geochemists being held in Florence, Italy. It’s based on new evidence uncovered by his research team and is sure to spark heated debate on the origin of life question.

Benner said the new scientific evidence “supports the long-debated theory that life on Earth may have started on Mars,” in a statement. Universe Today contacted Benner for further details and enlightenment.

“We have chemistry that (at least at the level of hypothesis) makes RNA prebiotically,” Benner told Universe Today. “AND IF you think that life began with RNA, THEN you place life’s origins on Mars.” Benner said he has experimental data as well.

First- How did ancient Mars life, if it ever even existed, reach Earth?

On rocks violently flung up from the Red Planet’s surface during mammoth collisions with asteroids or comets that then traveled millions of miles (kilometers) across interplanetary space to Earth – melting, heating and exploding violently before the remnants crashed into the solid or liquid surface.

An asteroid impacts ancient Mars and send rocks hurtling to space - some reach Earth — An asteroid impacts ancient Mars and send rocks hurtling to space – some reach Earth. Did they transport Mars life to Earth? Or minerals that could catalyze the origin of life on Earth?

“The evidence seems to be building that we are actually all Martians; that life started on Mars and came to Earth on a rock,” says Benner, of The Westheimer Institute of Science and Technology in Florida. That theory is generally known as panspermia.

To date, about 120 Martian meteorites have been discovered on Earth.

And Benner explained that one needs to distinguish between habitability and the origin of life.

“The distinction is being made between habitability (where can life live) and origins (where might life have originated).”

NASA’s new Curiosity Mars rover was expressly dispatched to search for environmental conditions favorable to life and has already discovered a habitable zone on the Red Planet’s surface rocks barely half a year after touchdown inside Gale Crater.

Furthermore, NASA’s next Mars orbiter- named MAVEN – launches later this year and seeks to determine when Mars lost its atmosphere and water- key questions in the Origin of Life debate.

Of course the proposed chemistry leading to life is exceedingly complex and life has never been created from non-life in the lab.

The key new points here are that Benner believes the origin of life involves “deserts” and oxidized forms of the elements Boron (B) and Molybdenum (Mo), namely “borate and molybdate,” Benner told me.

“Life originated some 4 billion years ago ± 0.5 billon,” Benner stated.

He says that there are two paradoxes which make it difficult for scientists to understand how life could have started on Earth – involving organic tars and water.

Life as we know it is based on organic molecules, the chemistry of carbon and its compounds.

But just discovering the presence of organic compounds is not the equivalent of finding life. Nor is it sufficient for the creation of life.

And simply mixing organic compounds aimlessly in the lab and heating them leads to globs of useless tars, as every organic chemist and lab student knows.

Benner dubs that the ‘tar paradox’.

Although Curiosity has not yet discovered organic molecules on Mars, she is now speeding towards a towering 3 mile (5 km) high Martian mountain known as Mount Sharp.

Upon arrival sometime next spring or summer, scientists will target the state of the art robot to investigate the lower sedimentary layers of Mount Sharp in search of clues to habitability and preserved organics that could shed light on the origin of life question and the presence of borates and molybdates.

It’s clear that many different catalysts were required for the origin of life. How much and their identity is a big part of Benner’s research focus.

“Certain elements seem able to control the propensity of organic materials to turn into tar, particularly boron and molybdenum, so we believe that minerals containing both were fundamental to life first starting,” says Benner in a statement. “Analysis of a Martian meteorite recently showed that there was boron on Mars; we now believe that the oxidized form of molybdenum was there too.”

The second paradox relates to water. He says that there was too much water covering the early Earth’s surface, thereby causing a struggle for life to survive. Not exactly the conventional wisdom.

“Not only would this have prevented sufficient concentrations of boron forming – it’s currently only found in very dry places like Death Valley – but water is corrosive to RNA, which scientists believe was the first genetic molecule to appear. Although there was water on Mars, it covered much smaller areas than on early Earth.”

Parts of ancient Mars were covered by oceans, lakes and streams of liquid water in this artists concept, unlike the arid and bone dry Martian surface of today. Subsurface water ice is what remains of Martian water.

I asked Benner to add some context on the beneficial effects of deserts and oxidized boron and molybdenum.

“We have chemistry that (at least at the level of hypothesis) makes RNA prebiotically,” Benner explained to Universe Today.

“We require mineral species like borate (to capture organic species before they devolve to tar), molybdate (to arrange that material to give ribose), and deserts (to dry things out, to avoid the water problem).”

“Various geologists will not let us have these [borates and molybdates] on early Earth, but they will let us have them on Mars.”

“So IF you believe what the geologists are telling you about the structure of early Earth, AND you think that you need our chemistry to get RNA, AND IF you think that life began with RNA, THEN you place life’s origins on Mars,” Benner elaborated.

“The assembly of RNA building blocks is thermodynamically disfavored in water. We want a desert to get rid of the water intermittently.”

I asked Benner whether his lab has run experiments in support of his hypothesis and how much borate and molybdate are required.

“Yes, we have run many lab experiments. The borate is stoichiometric [meaning roughly equivalent to organics on a molar basis]; The molybdate is catalytic,” Benner responded.

“And borate has now been found in meteorites from Mars, that was reported about three months ago.

At his talk, Benner outlined some of the chemical reactions involved.

Although some scientists have invoked water, minerals and organics brought to ancient Earth by comets as a potential pathway to the origin of life, Benner thinks differently about the role of comets.

“Not comets, because comets do not have deserts, borate and molybdate,” Benner told Universe Today.

Benner has developed a logic tree outlining his proposal that life on Earth may have started on Mars.

“It explains how you get to the conclusion that life originated on Mars. As you can see from the tree, you can escape that conclusion by diverging from the logic path.”

Finally, Benner is not one who blindly accepts controversial proposals himself.

He was an early skeptic of the claims concerning arsenic based life announced a few years back at a NASA sponsored press conference, and also of the claims of Mars life discovered in the famous Mars meteorite known as ALH 84001.

“I am afraid that what we thought were fossils in ALH 84001 are not.”

The debate on whether Earthlings are really Martians will continue as science research progresses and until definitive proof is discovered and accepted by a consensus of the science community of Earthlings – whatever our origin.

On Nov. 18, NASA will launch its next mission to Mars – the MAVEN orbiter. Its aimed at studying the upper Martian atmosphere for the first time.

“MAVENS’s goal is determining the composition of the ancient Martian atmosphere and when it was lost, where did all the water go and how and when was it lost,” said Bruce Jakosky to Universe Today at a MAVEN conference at the University of Colorado- Boulder. Jakosky, of CU-Boulder, is the MAVEN Principal Investigator.

MAVEN will shed light on the habitability of Mars billions of years ago and provide insight on the origin of life questions and chemistry raised by Benner and others.

Curiosity Conducts Science on the Go and Zooms to Stunning Mount Sharp

Curiosity Spies Mount Sharp – her primary destination. Curiosity will ascend mysterious Mount Sharp and investigate the sedimentary layers searching for clues to the history and habitability of the Red Planet over billions of years. But first she must safely trespass through the treacherous dark dunes fields. This mosaic was assembled from over 2 dozen Mastcam camera images taken on Sol 352 (Aug 2, 2013).

It’s never a dull moment for NASA’s Curiosity rover at T Plus 1 Year since touchdown on the Red Planet and T Minus 1 year to arriving at her primary target, the huge mountain overwhelming the center of the landing site inside Gale Crater.

Curiosity is literally and figuratively zooming in on stunningly beautiful and mysterious Mount Sharp (see our new mosaics above/below), her ultimate destination, while conducting ‘Science on the Go’ with her duo of chemistry labs – SAM and CheMin – and 8 other science instruments as she passes the 2 kilometer driving milestone today; Aug 20 !

“We are holding samples for drops to ChemMin and SAM when the science team is ready for it,” Jim Erickson, Curiosity Project Manager of NASA’s Jet Propulsion Laboratory (JPL), told Universe Today in an exclusive interview.

“Curiosity has landed in an ancient river or lake bed on Mars,” Jim Green, Director of NASA’s Planetary Science Division, told Universe Today.

So, those samples were altered by liquid Martian water – a prerequisite for life.

In fact the car sized rover has saved samples from both the ‘John Klein’ and ‘Cumberland’ drill sites collected previously in the ‘Yellowknife Bay’ area for analysis by the miniaturized labs in the rovers belly -when the time is right.

“Curiosity has stored a Cumberland sample and still has a John Klein sample on board for future use,” Erickson explained.

And that time has now arrived!

“We have put a sample from the Cumberland drill hole into SAM for more isotopic measurements,” reported science team member John Bridges in a blog update on Sol 363, Aug. 14, 2013.

“The sample had been cached within the robotic arm’s turret.”

Curiosity is multitasking – conducting increasingly frequent traverses across the relatively smooth floor of Gale Crater while running research experiments for her science handlers back here on Earth.

She’s captured stunning new views of Mount Sharp – rising 5 km (3 miles) high into the sky – and movies of Mars tiny pair of transiting moons while ingesting new portions of the drilled rock samples acquired earlier this year.

The sample analysis is still in progress.

“The SAM data have not all been received yet,” wrote science team member Ken Herkenhoff in a blog update.

Earlier analysis of sample portions from both ‘John Klein’ and ‘Cumberland’ revealed that the Yellowknife Bay area on Mars possesses the key mineral ingredients proving that Red Planet was once habitable and could have sustained simple microbial life forms.

The scientists are seeking further evidence and have yet to detect organic molecules – which are the building blocks of life as we know it.

Yellowknife Bay resembles a dried out river bed where liquid water once flowed eons ago when the Red Planet was far warmer and wetter than today.

As the 1 ton robot ascends Mount Sharp, she will examine sedimentary layers layed down on ancient Mars over hundreds of millions and perhaps billions of years of past history and habitability.

And just as the rover was celebrating 1 year on Mars on Aug 5/6, she found an intriguing sand dune on Sol 354. See our mosaic

“The rover paused to take images of its tracks after crossing a windblown ripple,” Herkenhoff reported.

As the six wheeled rover approaches Mount Sharp over the next year, she will eventually encounter increasing treacherous dunes that she must cross before beginning her mountain climbing foray.

As of today, Sol 369 (Aug. 20) Curiosity has broken through the 2 kilometer driving mark with a new 70 meter drive, snapped over 75,000 images and fired over 75,000 laser shots.

Mount Sharp is about 8 kilometers (5 miles) distant as the Martian crow flies.

How long will the journey to Mount Sharp require?

“Perhaps about a year,” Erickson told me. “We are trying to make that significantly faster by bringing autonav [autonomous navigation software] online.”

“That will help. But how much it helps really depends on the terrain.”

So far so good.

Meanwhile NASA’s next Mars orbiter called MAVEN (for Mars Atmosphere and Volatile Evolution), recently arrived at the Kennedy Space Center after a cross country flight.

Kennedy technicians are completing assembly and check out preparations for MAVEN’s blastoff to the Red Planet on Nov. 18 from Florida atop an Atlas V rocket similar to the one that launched Curiosity nearly 2 years ago.

And I’ll be at Kennedy to report up close on MAVEN’s launch.

Stay tuned.

NASA’s mega Mars rover Curiosity is celebrating 1 Year on the Red Planet since the dramatic landing on Aug. 6, 2012 by reveling in a string of groundbreaking science discoveries demonstrating that Mars could once have supported past life – thereby accomplishing her primary science goal – and with a promise that the best is yet to come!

“We now know Mars offered favorable conditions for microbial life billions of years ago,” said the mission’s project scientist, John Grotzinger of the California Institute of Technology in Pasadena.

“Curiosity has landed in an ancient river or lake bed on Mars,” Jim Green, Director of NASA’s Planetary Science Division, told Universe Today.

Curiosity is now speeding onwards towards Mount Sharp, the huge 3.4 mile (5. 5 km) mountain dominating the center of her Gale Crater landing site – and which is the primary destination of the mission.

During Year 1, Curiosity has transmitted over 190 gigabits of data, captured more than 71,000 images, fired over 75,000 laser shots to investigate the composition of rocks and soil and drilled into two rocks for sample analysis by the pair of state-of-the-art miniaturized chemistry labs housed in her belly – SAM & CheMin.

“From the sophisticated instruments on Curiosity the data tells us that this region could have been habitable in Mars’ distant past,” Green told me.

“This is a major step forward in understanding the history and evolution of Mars.”

And just in the nick of time for her 1 year anniversary, the car sized robot just passed the 1 mile (1.6 kilometer) driving mark on Aug. 1, or Sol 351.

Mount Sharp still lies roughly 5 miles (8 kilometers) distant – as the Martian crow flies.

“We will be on a general heading of southwest to Mount Sharp,” Jim Erickson, Curiosity Project Manager of NASA’s Jet Propulsion Laboratory (JPL), told Universe Today in an exclusive interview. See the NASA JPL route maps below.

“We have been going through various options of different planned routes.”

How long will the journey to Mount Sharp take?

“Perhaps about a year,” Erickson told me.

“We have put some new software – called autonav, or autonomous navigation – on the vehicle right after the conjunction period back in March 2013. This will increase our ability to drive.”

The total distance driven by NASA's Mars rover Curiosity passed the one-mile mark a few days before the first anniversary of the rover's landing on Mars. This map traces where Curiosity drove between landing at "Bradbury Landing" on Aug. 5, 2012, PDT, (Aug. 6, 2012 (Universal Time and EDT) and the position reached during the mission's 351st Martian day, or sol, (Aug. 1, 2013). The Sol 351 leg added 279 feet (85.1 meters) and brought the odometry since landing to about 1.05 miles (1,686 meters).

“We are trying to make that significantly faster by bringing the new autonav online. That will help. But how much it helps really depends on the terrain.”

So far the terrain has not been problematical.

“Things are going very well and we have a couple of drives under our belt,” said Erickson, since starting the long trek to Mount Sharp about a month ago.

The lower reaches of Mount Sharp are comprised of exposed geological layers of sedimentary materials that formed eons ago when Mars was warmer and wetter, and much more hospitable to microscopic life.

“It has been gratifying to succeed, but that has also whetted our appetites to learn more,” says Grotzinger. “We hope those enticing layers at Mount Sharp will preserve a broad diversity of other environmental conditions that could have affected habitability.”

Indeed, Curiosity’s breakthrough discovery that the surface of Mars possesses the key chemical ingredients required to sustain microbial life in a habitable zone, has emboldened NASA to start mapping out the future of Mars exploration.

NASA announced plans to start work on a follow on robotic explorer launching in 2020 and develop strategies for returning Martian samples to Earth and dispatching eventual human missions to Mars in the 2030’s using the new Orion capsule and SLS Heavy lift rocket.

“NASA’s Mars program is back on track with the 2016 InSight lander and the 2020 rover,” Jim Green, Director of NASA’s Planetary Science Division, told Universe Today in an interview.

“Successes of our Curiosity — that dramatic touchdown a year ago and the science findings since then — advance us toward further exploration, including sending humans to an asteroid and Mars,” said NASA Administrator Charles Bolden in a statement.

“Wheel tracks now, will lead to boot prints later.”

Following the hair-raising touchdown using with the never before used sky-crane descent thrusters, the science team directed the 1 ton robot to drive to a nearby area of interesting outcrops on the Gale crater floor – at a place called Glenelg and Yellowknife Bay.

Along the way, barely 5 weeks after landing, Curiosity found a spot laden with rounded pebbles at the Hottah outcrop of concretions that formed in an ancient stream bed where hip deep liquid water once flowed rather vigorously.

In February 2013, Curiosity conducted the historic first ever interplanetary drilling into Red Planet rocks at the ‘John Klein’ outcrop inside Yellowknife Bay that was shot through with hydrated mineral veins of gypsum.

The Yellowknife Bay basin looks like a dried up river bed.

Analysis of pulverized portions of the gray colored rocky powder cored from the interior of ‘John Klein’ revealed evidence for phyllosilicates clay minerals that typically form in pH neutral water. These starting findings on the crater floor were unexpected and revealed habitable environmental conditions on Mars – thus fulfilling the primary science goal of the mission.

“We have found a habitable environment [at John Klein] which is so benign and supportive of life that probably if this water was around, and you had been on the planet, you would have been able to drink it,” says Grotzinger, summing up the mission.

On the long road to Mount Sharp, Curiosity will make occasional stops for science.

This past week she captured rare sky watching images of the diminutive Martian moons – Phobos and Deimos – together!

Meanwhile, Curiosity’s 10 year old sister rover Opportunity Is trundling merrily along and will arrive shortly at her own mountain climbing goal on the opposite of Mars.

And NASA’s next Mars orbiter called MAVEN (for Mars Atmosphere and Volatile Evolution), has just arrived intact at the Kennedy Space Center after a cross country trip aboard a USAF C-17.

Technicians at Kennedy will complete final preparations for MAVEN’s blastoff to the Red Planet on Nov. 18 from the Florida Space Coast atop an Atlas V rocket.

On Tuesday, Aug 6, NASA will broadcast a half day of new programming on NASA TV commemorating the landing and discussing the science accomplished so far and what’s coming next.

And stay tuned for more astonishing discoveries during ‘Year 2’ on the Red Planet from our intrepid rover Curiosity – Starting Right Now !

MAVEN Takes Final Test Spins, Flexes Solar Panels Before Imminent Trek to Florida Launch Site

MAVEN is NASA’s next mission to Mars and in less than three days time the spacecraft ships out on a cross country trek for the first step on the long sojourn to the Red Planet.

But before all that, technicians took MAVEN for a final spin test, flexed her solar arrays and bombarded her with sound and a whole lot more.

On Aug. 2, MAVEN (Mars Atmosphere and Volatile EvolutioN Mission) journeys half a continent from its assembly facility at Lockheed Martin in Littleton, Colorado to the Kennedy Space Center and the Florida Space Coast aboard a USAF C-17.

Unlike Curiosity, which is roving across a crater floor on the Red Planet at this very moment, MAVEN is an orbiter with a first of its kind mission.

MAVEN is the first spacecraft from Earth devoted to investigating and understanding the upper atmosphere of Mars.

The goal is determining how and why Mars lost virtually all of its atmosphere billions of years ago, what effect that had on the climate and where did the atmosphere and water go?

To ensure that MAVEN is ready for launch, technicians have been busy this year with final tests of the integrated spacecraft.

Check out this video of MAVEN’s Dry Spin Balance Test

The spin balance test was conducted on the unfueled spacecraft on July 9, 2013 at Lockheed Martin Space Systems in Littleton, Colorado.

NASA says the purpose of the test “is to ensure that the fully integrated spacecraft is correctly balanced and to determine the current center of gravity. It allows the engineering team to fine-tune any necessary weight adjustments to precisely fix the center of gravity where they want it, so that it will perform as expected during the cruise to Mars.”

It was the last test to be completed on the integrated spacecraft before its shipment to Florida later this week.

This next video shows deployment tests of the two “gull-wing” solar panels at Lockheed Martin Space Systems.

Wingtip to wingtip, MAVEN measures 11.43 m (37.5 feet) in length.

In mid May, MAVEN was moved into a Thermal Vacuum Chamber at Lockheed Martin for 19 days of testing.

The TVAC test exposed MAVEN to the utterly harsh temperatures and rigors of space similar to those it will experience during its launch, cruise, and mission at Mars.

MAVEN is slated to blast off atop an Atlas V-401 rocket from Cape Canaveral Air Force Station, Florida on Nov. 18, 2013. The 2000 pound (900 kg) spacecraft will be housed inside a 4 meter payload fairing.

After a 10 month interplanetary voyage it will join NASA’s armada of four robotic spacecraft when it arrives in Mars orbit in September 2014.

Scientists hope that measurements from MAVEN will help answer critical questions like whether, when and how long the Martian atmosphere was once substantial enough to sustain liquid water on its surface and support life.

“What we’re doing is measuring the composition of the atmosphere as a measure of latitude, longitude, time of day and solar activities,” said Paul Mahaffy, of NASA’s Goddard Space Flight Center in Greenbelt, Md, and the principal investigator for MAVEN’s mass spectrometer instrument.

“We’re trying to understand over billions of years how the atmosphere has been lost.”
