It may be the chance of a lifetime for planetary science.

This October, a comet will brush past a planet, giving scientists a chance to study how it possibly interacts with a planetary atmosphere.

The comet is C/2013 A1 Siding Spring, and the planet in question Mars.  And although an impact of the comet on the surface of the Red Planet has long been ruled out, a paper in the May 2014 issue of Icarus raises the interesting possibility of possible interactions of the coma of A1 Siding Spring and the tenuous atmosphere of Mars. The study comes out of the Department of Planetary Sciences at the University of Arizona, the Belgian Institute for Space Aeronomy, the Institut de Planétologie et d’Astrophysique de Grenoble at the Université J. Fourier in France, and the Cooperative Institute for Research in Environmental Sciences at the University of Colorado in Boulder.

For the study, researchers considered how active Comet A1 Siding Spring may be at the time of closest approach on October 19th, 2014.

Discovered early last year by Robert McNaught from the Siding Spring Observatory in Australia, Comet A1 Siding Spring created a stir in the astronomical community when it was found that it will pass extremely close to Mars later this year. Further measurements of its orbit have since ruled this possibility out, but its passage will still be a close one, with a nominal passage of 138,000 kilometres from Mars. That’s about one third the distance from Earth to the Moon, and 17 times closer than the nearest recorded passage of a comet to the Earth, Comet D/1770 L1 Lexell in 1780. Mars’ outer moon Deimos has an orbital distance of about 23,500 kilometres.

And although the nucleus will safely pass Mars, the brush with its extended atmosphere might just be detectable by the fleet of spacecraft and rovers in service around Mars. At a distance of 1.4 Astronomical Units (A.U.) from the Sun during the encounter, the vast coma is expected to be comprised primarily of H2O. At an input angle of about 60 degrees, penetration was calculated in the study to impinge down and altitude of 154 kilometres to the topside of the Martian ionosphere, in the middle of the thermosphere.

Such an effect should linger for just over 4 hours, well over the interaction period of Mars’ atmosphere with the coma of just over an hour, centered on 18:30 UT on October 19th, 2014.

What kind of views might missions like HiRISE and MSL get of the comet remains to be seen, although NEOWISE and Hubble are already monitoring the comet for enhanced activity. The Opportunity rover is also still functioning, and Mars Odyssey and ESA’s Mars Express are still in orbit around the Red Planet and sending back data. But perhaps the most interesting possibilities for observations of the event are still en route: India’s Mars Orbiter Mission and NASA’s MAVEN orbiter arrive just before the comet. MAVEN was designed to study the upper atmosphere of Mars, and carries an ion-neutral mass spectrometer (NGIMS) which could yield information on the interaction of the coma with the Martian upper atmosphere and ionosphere. The NGIMS cover is slated for release just two days before the comet encounter. All spacecraft orbiting Mars may feel the increased drag effects of the encounter.

Proposals for using Earth-based assets for further observations of the comet prior to the event in October are still pending.  Amateur observers will be able to follow the approach telescopically, as Comet A1 Siding Spring is expected to reach +8th magnitude in October and pass 7’ from Mars in the constellation Ophiuchus as seen from the Earth. Mars just passed opposition last month, but both will be low to the south west at dusk for northern hemisphere observers in October.

It’s also interesting to consider the potential for interactions of the coma with the surfaces of the moons of Mars as well, though the net amount of water vapor expected to be deposited will not be large.

UPDATE: Check out this nifty interactive simulator which includes Comet A1 Siding Springs courtesy of the Solar System Scope:

The H2O coma of A1 Siding Spring is expected to have a radius of 150,000 kilometres when it passes Mars, just a shade over the nominal flyby distance.

“There is a more extended coma made up of H2O dissociation products (such as hydrogen and hydroxide) that extends for ~1,000,000 kilometres,” researcher at the Department of Planetary Sciences at the University of Arizona and lead author on the paper Roger Yelle told Universe Today.

“Essentially, Mars is in the outer reaches of the coma. The main ion tail misses Mars but there will be some ions from the comet that do reach Mars. The dust tail just misses Mars, which is fortunate.”

The paper also notes that significant perturbations of the upper atmosphere of Mars will occur if the cometary production rate is 10^28 s-1 or larger, which corresponds to about 300 kilograms per second.

“The MAVEN spacecraft will make very interesting observations,” Roger Yelle also told Universe Today. “The comet will perturb primarily the upper atmosphere of Mars and MAVEN was designed to study the upper atmosphere of Mars. Also, it’s just such an incredible coincidence that the comet arrives at Mars less than one month after MAVEN does. MAVEN is nominally in its checkout phase then, and the main science phase of the mission was not scheduled to start until November 1st. However, we are reassessing our plans to see what observations we can make. It’s all quite exciting, and we have to balance safety and the desire to make the best science measurements.”

It’s an unprecedented opportunity, that’s for sure… all eyes will be on the planet Mars and Comet A1 Siding Spring on October the 19th!

 

Space Science Stories to Watch in 2014

There’s an old Chinese proverb that says, “May you live in interesting times,” and 2013 certainly fit the bill in the world of spaceflight and space science. The past year saw spacecraft depart for Mars, China land a rover on the Moon, and drama in low Earth orbit to repair the International Space Station. And all of this occurred against a landscape of dwindling budgets, government shutdowns that threatened launches and scientific research, and ongoing sequestration.

But it’s a brave new world out there. Here are just a few space-related stories that we’ll watching in 2014:

Rosetta to Explore a Comet: On January 20, 2014, the European Space Agency will hail its Rosetta spacecraft and awaken it for its historic encounter with comet 67P/Churyumov-Gerasimenko later this year in August. After examining the comet in detail, Rosetta will then dispatch its Philae lander, equipped complete with harpoons and ice screws to make the first ever landing on a comet. Launched way back in 2004, Rosetta promises to provide the cosmic encounter of the year.

A1 Siding Springs vs. Mars: A comet discovery back in 2013 created a brief stir when researchers noted that comet C/2013 A1 Siding Springs would make a very close passage of the planet Mars on October 19th, 2014. Though refinements from subsequent observations have effectively ruled out the chance of impact, the comet will still pass 41,300 kilometres from the Red Planet, just outside the orbit of its outer moon Deimos. Ground-based observers will get to watch the +7th magnitude comet close in on Mars through October, as will a fleet of spacecraft both on and above the Martian surface.

Spacecraft En Route to Destinations: Though no new interplanetary missions are set to depart the Earth in 2014, there are lots of exciting missions currently underway and headed for worlds yet to be explored. NASA’s Dawn spacecraft is headed towards its encounter with 1 Ceres in February 2015. Juno is fresh off its 2013 flyby of the Earth and headed for orbital insertion around Jupiter in August 2016. And in November of this year, New Horizons will switch on permanently for its historic encounter with Pluto and its retinue of moons in July 2015.    

LUX & the Hunt for Dark Matter: It’s all around us, makes up the bulk of the mass budget of the universe, and its detection is THE name of the game in modern astrophysics. But just what is dark matter? Some tantalizing– and hotly contested –data came out late last year from of an unusual detector deep underground near Lead, South Dakota. The Large Underground Xenon experiment (LUX) looks for Weakly Interacting Massive Particles (WIMPs) interacting with 370 kilograms of super-cooled liquid Xenon. LUX requires its unique locale to block out interference from incoming cosmic rays. LUX is due to start another 300 day test run in 2014, and the experiment will add another piece to the puzzle posed by dark matter to modern cosmology, whether or not detections by LUX prove to be conclusive.

 The Hunt for Gravity Waves: Another story to watch may come out of Caltech’s twin gravity wave observatories when its Advanced LIGO system goes online later this year. Established in 2002, the Laser Interferometer Gravitational-Wave Observatory (LIGO) is comprised of two detectors: one in Hanford Washington and one outside of Livingston, Louisiana. The detectors look for gravity waves generated by merging binary pulsars and black holes. Though no positive detections have yet been made, Advanced LIGO with boast ten times the sensitivity and may pave the way for a new era of gravitational wave astronomy.

 Spacecraft reach Mars: 2014 is an opposition year for the Red Planet, and with it, two new missions are slated to begin operations around Mars: India’s Mars Orbiter Mission (MOM) also known as Mangalyaan-1 is slated to enter orbit on September 24th, and NASA’s MAVEN or Mars Atmosphere and Volatile Evolution Mission is set to arrive just 2 days earlier on September 22nd. MOM and MAVEN will join the Curiosity and Opportunity rovers, ESA’s Mars Express,  NASA’s Odyssey spacecraft and  the Mars Reconnaissance Orbiter in the quest to unlock the secrets of the Red Planet.

Space Tourism Takes Off: Virgin Galactic’s SpaceShipTwo passed a key milestone test flight in late 2013. Early 2014 may see the first inaugural flights by Virgin Galactic out of the Mohave Spaceport and the start of sub-orbital space tourism. SpaceShipTwo will carry two pilots and six passengers, with seats going for $250,000 a pop. Hey, room for any space journalists in there? On standby, maybe?

The First Flight of Orion: No, it’s not the first flight of the proposed sub-light interplanetary spacecraft that was to be propelled by atomic bombs… but the September launch of the Orion Multi-Purpose Crew Vehicle is the first step in replacing NASA’s capability to launch crews into space. Exploration Flight Test 1 (EFT-1) will be a  short uncrewed flight and test the capsule during reentry after two orbits. It’s to be seen if the first lunar orbital mission using an Orion MPCV will occur by the end of the decade.

 The First Flight of the Falcon Heavy: 2014 will be a busy year for SpaceX, starting with the launch of Thaicom-6 out of Cape Canaveral this Friday on January 3rd. SpaceX is now “open for business,” and expect to see them conducting more satellite deployments for customers and resupply missions to the International Space Station in the coming year. They’ll also be moving ahead with tests of their crew-rated version of the Dragon capsule in 2014. But one of the most interesting missions to watch for is the demo flight of the Falcon 9 Heavy slated to launch out of Vandenberg Air Force Base by the end of 2014.… more to come!

The Sunjammer Space Sail: An interesting mission moves in 2014 towards a January 2015 launch: LGarde’s Sunjammer solar sail. Sunjammer will test key solar sail technologies as well as deliver the Solar Wind Analyzer (SWAN) and the MAGIC Magnetometer to the L1 Earth-Sun Lagrange point. Sunjammer will launch on a Falcon-9 rocket and deploy a 1200 square metre solar sail weighing only 32 kilograms. This will be a great one for ground satellite-spotters to track as well as it heads out!

Gaia Opens for Business: Launched on a brilliant night-shot out of the Kourou Space Center in French Guiana on December 19th of last year, the European Space Agency’s Gaia space observatory will begin its astrometry mission in 2014, creating most accurate map yet constructed of our Milky Way Galaxy. But we also anticipate exciting new discoveries due to spin-offs from this mission, to include the discovery of new exoplanets, asteroids, comets and much more.

And as in years previous, the quest to explore brave new worlds will be done against the backdrop of tightening budgets. Just like in household budgets, modern spaceflight is a continual conflict between what we would wish and what we can afford. In recent years, no mission seems to be safe, and there have even been occasional congressional rumblings to pull the plug on missions already underway. Interesting times, indeed… 2014 promises to be an extraordinary time in spaceflight and space science, both on Earth and beyond.

India’s First Mars Probe ‘MOM’ Blasts Free of Earth Joining MAVEN in Race to Red Planet

CAPE CANAVERAL, FL – India’s first ever Mars probe ‘MOM’ successfully fired its main engine today (Dec. 1), blasting the craft free of the Earth’s sphere of influence forever to begin her nearly yearlong momentous voyage to the Red Planet.

Indian space engineers initiated the 440 Newton liquid fueled engine firing precisely as planned at 00:49 hrs (IST) on Sunday, Dec. 1, 2013 during a critical nail-biting burn lasting some 22 minutes.

The Trans Mars Insertion (TMI) firing propelled India’s Mars Orbiter Mission (MOM) away from Earth forever and placed the spacecraft on course for a rendezvous with the Red Planet on September 24, 2014 – where it will study the atmosphere and sniff for signals of methane.

Sunday’s Mars insertion burn imparted the vehicle with an incremental velocity of 647.96 meters per second (m/sec) consuming 198 kg of fuel.

The maneuver dubbed ‘The mother of all slingshots’, enabled MOM to finally achieve escape velocity and catapulted the 1,350 kilogram (2,980 pound) spacecraft on an historic flight streaking towards Mars.

And in a rare but rather delightful coincidence, MOM is not alone on her remarkable Martian sojourn. Following the triumphant engine burn, she now joins NASA’s MAVEN orbiter in a gallant marathon race to the Red Planet.

MOM was designed and developed by the Indian Space Research Organization’s (ISRO) at a cost of $69 Million and marks India’s inaugural foray into interplanetary flight.

“The Earth orbiting phase of the spacecraft ended,” with this maneuver said ISRO.

MOM is healthy and all systems are functioning normally.

While MOM was cycling Earth, ISRO scientists and engineers activated and tested the probes systems and science payloads.

They also turned the crafts color camera homewards to capture the “First ever image of Earth Taken by Mars Color Camera,” according to ISRO.

MOM is nicknamed ‘Mangalyaan’ – which in Hindi means ‘Mars craft.’

MOM’s journey bagen with a picture perfect Nov. 5 liftoff atop India’s highly reliable four stage Polar Satellite Launch Vehicle (PSLV) C25 from ISRO’s Satish Dhawan Space Centre SHAR, Sriharikota.

The PSLV booster precisely injected MOM into an initial elliptical Earth parking orbit of 247 x 23556 kilometers with an inclination of 19.2 degrees.

PSLV does not have sufficient thrust to send MOM streaking directly to the Red Planet.

Therefore since the flawless launch, the engine has been fired 6 times on November 7, 8, 9, 11, and 16 plus one supplementary maneuver to gradually raise the spacecrafts apogee from 23556 km to 192,874 km.

The most recent orbit raising maneuver occurred on Nov 16, 2013 with a burn time of 243.5 seconds and increased the apogee from 118,642 km to 192,874 km.

Today’s burn was the final one around Earth and absolutely crucial for setting her on course for Mars.

MOM was the first of two missions dispatched to Mars by Earthlings this November.

Half a world away, NASA’s MAVEN orbiter blasted off on Nov. 18 from Cape Canaveral Air Force Station, Florida atop an Atlas V booster on a direct path to the Red Planet.

The MOM spacecraft is now on traveling on a heliocentric elliptical trajectory to begin a 300 day long interplanetary voyage of more than 700 Million kilometers (400 Million miles) to the Red Planet.

Along the path to Mars, ISRO plans to conduct a series of Trajectory Correction Maneuvers (TCMs) using MOM’s Attitude and Orbit Control System (AOCS) thrusters to precisely navigate the probe to the point required to achieve orbit around the Red Planet

Following the ten month cruise through space the orbital insertion engine will fire for a do or die burn on September 24, 2014 placing MOM into an 377 km x 80,000 km elliptical orbit around Mars.

MOM will reach Mars vicinity just two days after MAVEN’s arrival on Sept. 22, 2014.

If all continues to goes well, India will join an elite club of only four who have launched probes that successfully investigated the Red Planet from orbit or the surface – following the Soviet Union, the United States and the European Space Agency (ESA).

Both MAVEN and MOM’s goal is to study the Martian atmosphere, unlock the mysteries of its current atmosphere and determine how, why and when the atmosphere and liquid water was lost – and how this transformed Mars climate into its cold, desiccated state of today.

Although MOM’s main objective is a demonstration of technological capabilities, the probe is equipped with five indigenous instruments to conduct meaningful science – including a multi color imager and a methane gas sniffer to study the Red Planet’s atmosphere, morphology, mineralogy and surface features. Methane on Earth originates from both geological and biological sources – and could be a potential marker for the existence of Martian microbes.

MOM’s 15 kg (33 lb) science suite comprises:

MCM: the tri color Mars Color Camera images the planet and its two tiny moons, Phobos and Deimos

LAP: the Lyman Alpha Photometer measures the abundance of hydrogen and deuterium to understand the planets water loss process

TIS: the Thermal Imaging Spectrometer will map surface composition and mineralogy

MENCA: the Mars Exospheric Neutral Composition Analyser is a quadrapole mass spectrometer to analyze atmospheric composition

MSM: the Methane Sensor for Mars measures traces of potential atmospheric methane down to the ppm level.

Scientists will be paying close attention to whether MOM detects any atmospheric methane to compare with measurements from NASA’s Curiosity rover – which found ground level methane to be essentially nonexistent – and Europe’s upcoming 2016 ExoMars Trace Gas Orbiter.

India’s MOM – ‘Mangalyaan’ mission is expected to continue gathering measurements at the Red Planet for at least six months and hopefully much longer.

MAVEN could operate for a decade or longer and is also crucial for relaying images and data collected by NASA’s current and upcoming surface rovers and landers.

Although they were developed independently and have different suites of scientific instruments, the MAVEN and MOM science teams will “work together” to unlock the secrets of Mars atmosphere and climate history, MAVEN’s top scientist told Universe Today.

“We have had some discussions with their science team, and there are some overlapping objectives,” Bruce Jakosky told me. Jakosky is MAVEN’s principal Investigator from the University of Colorado at Boulder.

“At the point where we [MAVEN and MOM] are both in orbit collecting data we do plan to collaborate and work together with the data jointly,” Jakosky said.

Stay tuned here for continuing MOM and MAVEN news and Ken’s MAVEN and SpaceX Falcon 9 launch reports from on site at the Kennedy Space Center press center and Cape Canaveral Air Force Station, Florida.

India’s MOM Mars Probe Images Earth’s Children Prior to Nail Biting Red Planet Insertion

CAPE CANAVERAL, FL – MOM is looking at you, kid!

And if the spectacular new image of billions of Earth’s children captured by India’s Mars Orbiter Mission (MOM) is any indication (see above), then we can expect absolutely gorgeous scenes of the Red Planet once the groundbreaking probe arrives there in September 2014.

But despite all that’s been accomplished so far, the space drama is still in its infant stages – because MOM still needs to ignite her thrusters this weekend in order to achieve escape velocity, wave good bye to Earth forever and eventually say hello to Mars!

The picture – snapped from Earth orbit – is focused on the Indian subcontinent, the probes origin.

MOM has captured the imagination of space enthusiasts worldwide.

And she’s the pride of all India – as the country’s first ever interplanetary space mission.

During testing of the MOM probes payloads – while it’s still flying in a highly elliptical orbit around our Home Planet – engineers from India’s space agency turned the crafts camera homewards to capture the “First ever image of Earth Taken by Mars Color Camera,” according to the Indian Space Research Organization (ISRO).

The beautiful image was taken on Nov. 20 at around 1350 hrs (IST) from a height of almost 70,000 km above earth and has a spatial resolution of 3.5 km, said ISRO.

The image also gives a rather good approximation of what MOM’s color camera will actually see from apoapsis after reaching the Red Planet since the probe will enter a similarly highly elliptical orbit around Mars – ranging in altitude from 366 kilometers (km) x 80,000 kilometers (km).

Following a 10 month interplanetary cruise, MOM is due to arrive in the vicinity of Mars on September 24, 2014 to study the Red Planets’ atmosphere.

At that time, the 440 Newton liquid fueled main engine must fire precisely as planned during the absolutely essential Mars orbital insertion burn to place the probe into orbit about Mars.

But before MOM can accomplish anything at Mars, she must first successfully fire her main engine – to complete the crucial departure from Earth and Trans Mars Insertion (TMI) scheduled for this Saturday!

MOM’s picture perfect Nov. 5 liftoff atop India’s highly reliable four stage Polar Satellite Launch Vehicle (PSLV) C25 from the ISRO’s Satish Dhawan Space Centre SHAR, Sriharikota, precisely injected the spacecraft into an initial elliptical Earth parking orbit of 247 x 23556 kilometers with an inclination of 19.2 degrees.

Since then the engine has fired 6 times to gradually raise the spacecrafts apogee.

The most recent orbit raising maneuver occurred at 01:27 hrs (IST) on Nov 16, 2013 with a burn time of 243.5 seconds increased the apogee from 118,642 km to 192,874 km.

The nail-biting final main engine burn of 1351 seconds is set for this weekend on Dec. 1. It will place MOM on a precise interplanetary trajectory to the Red Planet.

If all continues to goes well, India will join an elite club of only four who have launched probes that successfully investigated the Red Planet from orbit or the surface – following the Soviet Union, the United States and the European Space Agency (ESA).

The low cost $69 Million MOM mission is the first of two new Mars orbiter science probes from Earth that flawlessly blasted off for the Red Planet this November.

Half a world away, NASA’s $671 Million MAVEN orbiter launched as scheduled on Nov. 18 – from Cape Canaveral, Florida.

Both MAVEN and MOM’s goal is to study the Martian atmosphere, unlock the mysteries of its current atmosphere and determine how, why and when the atmosphere and liquid water was lost – and how this transformed Mars climate into its cold, desiccated state of today.

The MAVEN and MOM science teams will “work together” to unlock the secrets of Mars atmosphere and climate history, MAVEN’s top scientist Prof. Bruce Jakosky told Universe Today.

MAVEN thunders to Space on Journey to Study Red Planet’s Watery History and Potential for Life

KENNEDY SPACE CENTER, FL – NASA’s Mars Atmosphere and Volatile Evolution (MAVEN) space probe thundered to space today (Nov. 18) following a flawless blastoff from Cape Canaveral Air Force Station’s Space Launch Complex 41 at 1:28 p.m. EST atop a powerful Atlas V rocket.

“Hey Guys we’re going to Mars!” gushed Bruce Jakosky, MAVEN’s Principal Investigator at a post launch briefing for reporters.

“Now I am a Martian,” beamed Jakosky gleefully, as well as is everyone else who has worked on MAVEN since the project was conceived some ten years ago, he noted.

Today’s countdown was absolutely perfect culminating in a spectacular and on time lift off that rumbled across the Florida Space Coast to the delight of cheering crowds assembled for the historic launch aimed at discovering the history of water and habitability stretching back over billions of years on Mars.

“I take great pride in the entire team,” said Jakosky.

“Everyone was absolutely committed to making this work.”

The $671 Million MAVEN spacecraft separated from the Atlas Centaur upper stage some 52 minutes after liftoff, unfurled its wing like solar panels to produce life giving power and thus began a 10 month interplanetary voyage to the Red Planet.

“We’re currently about 14,000 miles away from Earth and heading out to the Red Planet right now,” said MAVEN Project Manager David Mitchell of NASA’s Goddard Space Flight Center at the briefing, after the 5,400-pound spacecraft had been soaring through space for barely two and a half hours.

“The first trajectory correction maneuver (TCM) is set for Dec. 3,” added Mitchell. There are a minimum of four TCM’s to ensure that the majestic probe remains precisely on course for Mars.

“Safe travels MAVEN!” said Mitchell. “We’re with you all the way.”

It will take the spacecraft 10 months to reach the Red Planet, with arrival scheduled for Sept. 22, 2014.

Jakosky noted that while the launch is a big milestone, it’s just the beginning.

MAVEN’s purpose is to accomplish world class science after arriving at Mars and completing a check-out period before it can finally begin collecting science data.

MAVEN will answer key questions about the evolution of Mars, its geology and the potential for the evolution of life.

“MAVEN is an astrobiology mission,” says Jakosky.

Mars was once wet billions of years ago, but no longer. Now it’s a cold arid world, not exactly hospitable to life.

“We want to determine what were the drivers of that change?” said Jakosky. “What is the history of Martian habitability, climate change and the potential for life?”

MAVEN will study Mars upper atmosphere to explore how the Red Planet may have lost its atmosphere over billions of years. It will measure current rates of atmospheric loss to determine how and when Mars lost its atmosphere and water.

The MAVEN probe carries nine sensors in three instrument suites.

The Particles and Fields Package, provided by the University of California at Berkeley with support from CU/LASP and NASA’s Goddard Space Flight Center in Greenbelt, Md., contains six instruments to characterize the solar wind and the ionosphere of Mars. The Remote Sensing Package, built by CU/LASP, will determine global characteristics of the upper atmosphere and ionosphere. The Neutral Gas and Ion Mass Spectrometer, built by Goddard, will measure the composition of Mars’ upper atmosphere.

“We need to know everything we can before we can send people to Mars,” said Dr. Jim Green, NASA’s Director of Planetary Science at NASA HQ in Washington, DC.

“MAVEN is a key step along the way. And the team did it under budget!” Green elaborated. “It is so exciting!”

Over the course of its one-Earth-year primary mission, MAVEN will observe all of Mars’ latitudes at altitudes ranging from 93 miles to more than 3,800 miles.

MAVEN will execute five deep dip maneuvers during the first year, descending to an altitude of 78 miles. This marks the lower boundary of the planet’s upper atmosphere.

How NASA Kept MAVEN’s Launch Date During The Government Shutdown

As NASA Social attendees gather for NASA’s Mars Atmosphere and Volatile EvolutioN (MAVEN) spacecraft’s date with space today, NASA administrator Charles Bolden recalled that time in October when it looked like MAVEN may have had to lose its launch window for two years because of the government shutdown.

“It was a very complicated process that we were engaged in, back in Washington, where the term used was ‘accepted activity’,” Bolden said in an interview with Universe Today.

For launch preparations to proceed during that 16-day shutdown, Bolden and other officials engaged in the mission needed to make the case that MAVEN was vital. The mission’s science focus, examining the atmosphere of Mars and tracking down the planet’s lost water, is usually what is talked about when justifying its activities to the public.

It was a different argument, however, that got MAVEN’s launch preparations on track: “imminent risk to life or property,” Bolden said, specifically with regard to its role in sending huge data files from the Curiosity and Opportunity rovers on the surface (as well as the forthcoming Mars 2020 rover, if that gets off the ground.)

“If we had lost the opportunity to launch MAVEN, we had to slip another two-year period of time, and during that period of time it was likely that the current communications relays working on Mars would die because the ones that were there were over their current design lifetime,” Bolden said, referring to the Mars Reconnaissance Orbiter and Mars Odyssey.

Launch work was halted for a couple of days, and then more time had to be spent bringing the crew back in to prepare the spacecraft, but Bolden said the parties involved were able to “make it up without any major problem.” Other programs, however, took a hit. Bolden said there has been a loss in confidence in NASA workers getting the Orion human spacecraft and next-generation Space Launch System ready for a crewed mission late this decade. Bolden cites Orion as a stepping stone for NASA’s dream of sending astronauts away from Earth, including Mars missions.

“The biggest impact, to be quite honest, was not on the program but on the people,” he said. “Their attitude towards working in the government is they’re very proud of what they do, they know they do an exceptional job, and they felt the Congress — at the time — didn’t have respect for what we do. We’re spending a lot of time now trying to repair some … morale.”

Another one of Bolden’s tasks these days is to allay concerns in the planetary science community that the focus on Mars may be coming at a detriment to the outer planets. NASA’s planetary science budget took a big hit in fiscal 2013 and some critics say the agency’s focus now is on developing Mars missions over those to the other planets.

“My response has been, and continues to be, what we’re trying to do is we’re trying to figure out better ways” for the planetary science community to participate, Bolden said.

Characterizing the multi-billion dollar missions such as Cassini as “a thing of the past,” Bolden said the agency is now looking at creating missions that are smaller, but more technologically advanced than the behemoth missions NASA used to send when its budgets weren’t quite so tight. He added that he feels the smaller missions could still accomplish the objectives of the larger ones.

“I would hope that the scientific community … will help us define ways that we can design and build satellites that we can fly on a more frequent basis, that cost us a little less money, so you end up getting the same amount — if not more — of data,” Bolden said. He also cited more frequent missions as a boon to inspiring younger students for science, since the big missions might have a gap of 10 or more years between them.

Bolden, a former astronaut, commanded the STS-45 mission in in 1992 that did Earth atmospheric science of its own using the payload ATLAS-1. “I think I have bored the Mars atmospheric scientists to death relating it to what we’re hoping to do with MAVEN in the upper atmosphere,” he joked, but added the science is somewhat related.

NASA hopes MAVEN will help scientists better understand “what happened with the upper atmosphere of Mars that went it to go from green and fertile, to where it is today — a cold, icy planet,” he said. “In doing so, we hope we’ll learn about our own planet.”

MAVEN’s launch window opens at 1:38 p.m. EST (6:38 p.m. UTC) today (Nov. 18). The only major issue NASA was working at the time of the interview (roughly 6 a.m. EST, or 1 p.m. UTC) was weather, which was only 60% go, Bolden said.

KENNEDY SPACE CENTER, FL – NASA’s Mars bound MAVEN spacecraft was rolled out to the seaside launch pad on Saturday Nov. 16 on Florida’s space coast on an expedition to study the Red Planet’s atmosphere and its potential for astrobiology.

All systems are “GO” for MAVEN and the powerful Atlas booster that will set the probe streaking on a ten month interplanetary journey to the Red Planet.

MAVEN is targeted to launch Monday, Nov. 18 at 1:28 p.m. EST atop a United Launch Alliance Atlas V 401 rocket from Cape Canaveral Air Force Station in Florida.

The battery is being charged. After a day of rest for the launch pad crew, the countdown is set to resume at about 6:28 a.m. on Monday.

The Atlas launch window extends for 2 hours until about 3:30 p.m.

The weather outlook is somewhat iffy with a 60% chance of favorable conditions at launch time. The main threats are rain, winds and clouds.

Crowds of spectators are descending on Florida to view the historic launch and the local hotels are filling up. And I’ve spoken to many enthusiastic folks and kids hoping to witness a space spectacular.

Mars beckons humans for centuries as a place of myths and mysteries.

MAVEN will answer key questions about the evolution of Mars, its geology and the potential for the evolution of life

“MAVEN is an astrobiology mission,” said Bruce Jakosky, MAVEN’s Principal Investigator from the University of Colorado at Boulder, at NASA’s Kennedy Space Center.

Mars was once wet billions of years ago, but no longer. Now it’s a cold arid world, not exactly hospitable to life.

“We want to determine what were the drivers of that change?” said Jakosky. “What is the history of Martian habitability, climate change and the potential for life?”

NASA’s MAVEN Mars orbiter – which stands for Mars Atmosphere and Volatile Evolution – is the first real attempt to investigating these fundamental questions that hold the key to solving the Martian mysteries perplexing the science community.

The 5,400 pound MAVEN probe carries nine sensors in three instrument suites.

The Particles and Fields Package, provided by the University of California at Berkeley with support from CU/LASP and NASA’s Goddard Space Flight Center in Greenbelt, Md., contains six instruments to characterize the solar wind and the ionosphere of Mars. The Remote Sensing Package, built by CU/LASP, will determine global characteristics of the upper atmosphere and ionosphere.

KENNEDY SPACE CENTER, FL – Star Trek actor and space enthusiast LeVar Burton stars in a new action packed NASA public service announcement (PSA) about the agency’s next Mars-bound spacecraft, the Mars Atmosphere and Volatile Evolution (MAVEN) spacecraft slated for blast off in barely two days time on Nov. 18 from the Florida Space Coast.

Burton played the beloved character of chief engineer ‘Geordi LeForge’ aboard the legendary Starship Enterprise on “Star Trek: The Next Generation” – known by audiences worldwide.

And Burton gives an appropriately other worldly narration in the NASA PSA containing exciting new animations explaining the goals and science behind the MAVEN Mars orbiter and how it will accomplish its tasks.

I was privileged to meet chief engineer ‘Geordi LeForge’ at a prior NASA launch event.

He is genuinely and truly dedicated to advancing science and education through his many STEM initiatives and participation in educational programming like the NASA PSA.

MAVEN will study the Red Planet’s atmosphere like never before and in unprecedented detail and is the first mission dedicated to studying Mars upper atmosphere.

MAVEN’s is aimed at unlocking one of the greatest Martian mysteries; Where did all the water go ? And when did the Red Planet’s water and atmosphere disappear ?

MAVEN’s suite of nine science instruments will help scientists understand the history, mechanism and causes of the Red Planet’s dramatic climate change over billions of years.

Burton’s PSA will be used at MAVEN scheduled events around the country and will also be shared on the web and social media, according to NASA. The goal is to educate the public about MAVEN and NASA’s efforts to better understand the Red Planet and the history of climate change there.

Be sure to check out the new video – below:



Video caption: NASA is returning to Mars! This NASA Public Service Announcement regarding the MAVEN mission is presented by LeVar Burton in which he shares the story about NASA’s Mars Atmosphere and Volatile Evolution mission—or MAVEN—and how it will explore Mars’ climate history and gather clues about the question scientists have been asking for decades. MAVEN will look at specific processes at Mars that led to the loss of much of its atmosphere…and MAVEN data could tell scientists a lot about the history of climate change on the Red Planet.

“NASA is thrilled to have LeVar Burton explain this mission to the greater public,” said Bert Ulrich, NASA’s multimedia liaison for film and TV collaborations in a NASA statement. “Thanks to Burton’s engaging talents and passion for space exploration, audiences of all ages will be able to share in the excitement of NASA’s next mission to Mars.”

MAVEN is targeted to launch Monday, Nov. 18 at 1:28 p.m. EST atop a United Launch Alliance Atlas V rocket from Cape Canaveral Air Force Station in Florida.

MAVEN’s Quest – Where Did Mars Water Go?

KENNEDY SPACE CENTER, FL – MAVEN, NASA’s next spacecraft launching to the Red Planet in barely three days time on Nov. 18 seeks to unlock one of the greatest Martian mysteries; Where did all the water go ?

From the accumulated evidence so far scientists believe that billions of years ago, Mars was gifted with a thick atmosphere like Earth and liquid water flowed across the surface.

The Red Planet was far bluer, warmer, wetter and hospitable to life four billion years ago – truly a lot more Earth-like.

And then Mars lost its atmosphere starting somewhere around 3.5 to 3.7 Billion years ago. As the atmosphere thinned and the pressure decreased, the water evaporated and Mars evolved into the cold arid world we know today.

But why and exactly when did Mars undergo such a radical climatic transformation?

“Where did the water go and where did the carbon dioxide go from the early atmosphere? What were the mechanisms?” asks Bruce Jakosky, MAVEN’s Principal Investigator from the University of Colorado at Boulder

Although there are lots of theories, NASA’s MAVEN Mars orbiter – which stands for Mars Atmosphere and Volatile Evolution – is the first real attempt to investigating these fundamental questions that hold the key to solving the Martian mysteries perplexing the science community.

“We don’t know the driver of the change,” explains Jakosky.

By studying and understanding specific processes in the upper atmosphere of Mars, MAVEN’s seeks to determine how and why Mars atmosphere and water disappeared billions of years ago and what effect that had on the history of climate change and habitability.

“The major questions about the history of Mars center on the history of its climate and atmosphere and how that’s influenced the surface, geology and the possibility for life,” says Jakosky.

MAVEN is equipped with three instrument suites holding nine science instruments

MAVEN will focus on understanding the history of the atmosphere, how the climate has changed through time, and how that influenced the evolution of the surface and the potential for habitability by microbes on Mars.”

“That’s what driving our exploration of Mars with MAVEN,” said Jakosky

The Neutral Gas and Ion Mass Spectrometer, built by Goddard, will measure the composition of Mars’ upper atmosphere.

I personally inspected MAVEN inside the clean room at the Kennedy Space Center on Sept. 27 with fellow journalists when the solar arrays were fully unfurled.

The probe spanned 37 feet in length from wingtip to wingtip.

Since then MAVEN has been folded and encapsulated inside the payload fairing, transported to the pad at Launch Complex 41 and hoisted on top of the Atlas V rocket on Cape Canaveral Air Force Station (CCAFS) in Florida.

The $671 Million MAVEN spacecraft has been powered on and awaits liftoff.

MAVEN is the second of two Mars bound probes launching from Earth this November.

India’s Mars Orbiter Mission (MOM) spacecraft staged a spectacular lift off from the Indian spaceport on Nov. 5. Both probes are due to arrive at the Red Planet in September 2014.
