While 2014 budget negotiations are not finalized yet, there’s already some noise of concern in different space communities that depend on NASA. Here’s a brief roundup of some of the news lately:
Could the Cassini Saturn mission get the axe? Wired’s Adam Mann warns that NASA may not be able to fund all of its planetary science missions in the coming year. Based on a statement that Jim Green, NASA’s planetary science director, made to an agency advisory council earlier this month, Mann narrows in on the Curiosity and Cassini missions as the big flagship missions that are requiring the most in terms of resources. Cassini is functioning perfectly and providing reams of data from Saturn and its moons, causing concern from planetary scientists about losing it early.
Only one commercial crew partner? NASA issued a cautious news release this week saying it is prepared to launch Americans from their own soil in 2017, “subject to the availability of adequate funding.” The agency is now moving into a new phase of its commercial crew program called Commercial Crew Transportation Capability (CCtCap), saying it is prepared to “award one or more CCtCap contracts no later than September 2014.” That means that the three companies currently funded — Boeing Co., Sierra Nevada Corp. and SpaceX — may face stiff competition for more money.
New report suggesting stopping NASA’s human spaceflight program: Before reading any further, do not jump to conclusions — making recommendations like this is a common practice by the Congressional Budget Office, which looks at all possibilities as it presents options for spending. Still, Space Politics’ Jeff Foust presents the report and generates some interesting comments after his story about the value of human spaceflight. For context, NASA and its international agency partners will need to make a decision fairly soon about continuing space station operations past 2020, so it’s possible the human spaceflight program could change.
What do you think of these proposals? Let us know in the comments.

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.

A full-sized MRI on the International Space Station would take up a lot of size and mass, meaning the astronauts have to use different machines to learn about the body.

OTTAWA, CANADA – The University of Saskatchewan hopes to fly a wrist-sized MRI to the International Space Station by 2016 in a standard Progress cargo flight, according to Gordon Sarty, a university professor specializing in medical imaging. Why is this important? It will help doctors keep track of the astronauts’ bone strength on orbit, Sarty says of his team’s invention.
With NASA aiming to run its first one-year mission to the station in 2015, there is renewed emphasis on keeping track of all the nasty things microgravity does to astronauts’ bodies in space. Crew members spend two hours a day exercising, but still come back to Earth having trouble balancing, with weaker bones and muscles, and possible facing changes to organs such as the eyes.
Although NASA runs MRIs on crew members before and after flights, Sarty said the ability to get even a simple scan in orbit would be useful — and quite quick. It would take just five to 10 minutes to perform, and would be simple for anyone to do as the scan would commence at the touch of a button.
There are many ideas for investigating bone health in astronauts. Here, astronaut Doug Wheelock uses an Acoustic Vibration Bone Quality Measurement Device in 2004 during NEEMO 6, one of an underwater series of missions NASA ran to simulate space exploration. Credit: NASA
The Canadian Space Agency is allowed just 44 kilograms (97 pounds) to get the MRI to orbit under its utilization agreement on station (which is based on funding). A full-size MRI able to fit in a standard payload rack would have been about 800 kilograms (1,765 pounds), Sarty said.
Modifications are necessary. Rather than using superconducting magnets to do the work in orbit, Sarty’s design proposes manipulating radio frequency waves instead. (More technical details here.) Sarty’s team currently has a $240,000 grant from the CSA to develop the technology, which goes for about the next year.
Sarty said the International Space Station needs to be outfitted to a “Level 4” standard of medical care, meaning that it would include medical imaging on board to help monitor crew health. NASA’s Human Research Program Utilization Plan for the station (published in 2012) identifies the addition of ultrasound as a boon to ISS’ medical capabilities.

As for “Level 4”, the NASA Space Flight Human Human System Standard (latest version available expired in 2012) defines Level 4 as “A moderate to high level of potential risk exists that personnel may experience medical problems on orbit. Risk to the mission is greater for medical issues beyond routine ambulatory medicine.” It also assumes a return to Earth can take days. Level 4 applies to Earth, lunar or planetary missions greater than 30 days, but no more than 210 days.
The upside for Earth research? The portable MRI could be repurposed, in a sense, to bring into more remote regions. This is especially true of Canada, where tens of thousands of people live in scattered communities in the remote north.

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.

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.”

OTTAWA, CANADA – Astronauts appear to hold their heads more rigidly in relation to their trunks after returning to Earth from multi-month spaceflights, which may affect how they balance themselves back on Earth, according to ongoing research.
A note of caution: the sample size is small (six astronauts so far) and the research is still being conducted by the University of Houston and NASA. So this isn’t finalized in any sense. The early studies, however, shows that people returning to Earth may be changing their “strategy”, said Ph.D. student Stefan Madansingh.
“The changing strategy might put you at higher risks of falls as you ambulate around your environment, and if you are on Mars and you fall and break your hip, that is the start of a very bad day,” he said in a speech.

Generally, NASA is interested in learning about changes in cardiovascular, balance and muscle function after six-month spaceflights or more, when they are “like spaghetti people,” Madansingh said. Over the years, astronauts have shown changes in inner eye pressure, bone density, muscles and their balance, among other things.
To obtain the information, NASA has had astronauts walking around a simple obstacle course, which they encourage astronauts to complete at a comfortable walking pace. They’ll weave around pylons, climb ladders and do other simple tasks.
Tests are performed at 180, 60 and 30 days before launch, then one, six and 30 days after landing. (In the shuttle era, astronauts would do these types of tests immediately after landing, but these days there’s a day-long flight from Kazakhstan before arriving in Houston.) Some tests are started from a lying position, and some from a sitting position.

It takes more time for astronauts to complete the obstacle course after coming back from space, Madansingh said, and his ongoing research looks at the relation between the head and trunk as the astronauts are doing so.
As controls, NASA uses bed rest subjects, who are people voluntarily spending 70 days in a head-down position without getting up once, even to go to the bathroom. “I think it’s absolutely bonkers,” Madansingh joked, but added that the bed rest subjects don’t show that same head-trunk changes that returning astronauts do. More research will be needed to learn why, he said.

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.

“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 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

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.

Hail damage is visible on the external tank attached to Space Shuttle Atlantis on the launchpad during a strong thunderstorm that passed through Kennedy Space Center on Feb. 26, 2007. Credit: NASA/KSC.
The STS-117 mission was supposed to carry solar panels and connecting trusses up to the station, so changing the shuttle rotation would affect construction. What to do?
“I’ve got this tank that takes us a bit over two years to manufacture, and essentially it looks like your car here that was peppered by a hailstorm, and what are we going to do?” said Bill Gerstenmaier, NASA’s associate administrator of the human exploration and operations directorate, speaking today (Nov. 14) at the Canadian Space Society’s annual summit in Ottawa, Canada.
“Mike Griffin was the administrator at the time. He said, ‘Get rid of that tank and put another one out there,’ and we didn’t have another one.”
To respond to the problem — based mostly on the word of two technicians who felt repairs were possible, Gerstenmaier said — NASA set out to fix the problem. Communications flew between the launch site in Florida and the manufacturer in New Orleans. NASA had a program that kept track of tiles on the shuttle, and modified it to take care of the dings. The mission lifted off successfully, using the repaired tank, in June 2007 — three months after the incident.

Gerstenmaier said this demonstrates that it’s possible to be innovative on reduced budgets, and drew parallels to what NASA is facing right now as it fights through fiscal 2014 budget discussions.
“We have to turn them not into a ‘woe is me’ kind of discussion, but rise above that and pull out the innovation, and that’s what we’re doing in this budget,” he said.
Reduced budgets have helped NASA make use of reduced resources before, he added. It encouraged the agency to tender out to commercial companies (such as SpaceX) for cargo flights to the space station, even though development would occur on the fly. Gerstenmaier, however, did not address concerns that the new budget could cut back commercial crew budgets even further.
Another example of past innovation by both NASA and the Canadian Space Agency, Gerstenmaier said, occurred when the space station’s Canadarm2 robotic arm was adapted to capture these commercial cargo vehicles and berth them into station. If the Canadians had been told in the 1990s — when the space station was just beginning — that the arm would have been required to do this, they likely would have balked, Gerstenmaier said.
While only touching lightly on the ongoing budget discussions, Gerstenmaier did say NASA is keeping an eye on the efforts of Canadian astronaut Chris Hadfield and others as it continues to develop outreach. He joked that the movie “Gravity” really showed the divide between space fans and the general public.
“We see it one way and [say] that isn’t physically correct … it doesn’t actually look like that in space. This is wrong,” he said. “Then the general public says ‘this is really stressful, she lost her child,’ — they’re in this other mode. We’re sitting next to each other in the theater. My non-space colleague is crying, and I’m saying this violates the law of physics.”
Some of Gerstenmaier’s past work in NASA includes top managerial positions in the shuttle//Mir program, space shuttle program integration, the International Space Station and NASA’s space operations directorate (where he oversaw the final 21 space shuttle missions.)

The familiar blotches that make up “the man in the moon”, from the vantage point of Earth, happened because the moon’s crust is thinner on the near side than the far side to our planet, new research reveals.
The twin GRAIL spacecraft provided the most accurate sizes yet of lunar impact craters on the moon, providing more insight into what happened when Earth’s closest large neighbor was hammered with meteorites over billions of years.
“Since time immemorial, humanity has looked up and wondered what made the man in the moon,” stated Maria Zuber, GRAIL principal investigator from the Massachusetts Institute of Technology in Cambridge.

“We know the dark splotches are large, lava-filled, impact basins that were created by asteroid impacts about four billion years ago. GRAIL data indicate that both the near side and the far side of the moon were bombarded by similarly large impactors, but they reacted to them much differently.”
The moon’s near side is easily visible in a telescope, but it’s hard to measure the size of the impacts because lava is obscuring their dimensions. The GRAIL spacecraft, however, peered at the internal structure of the moon and also produced information showing how thick the crust is. This showed that there are more, bigger craters on the closer side of the moon to us than the further side.

“Impact simulations indicate that impacts into a hot, thin crust representative of the early moon’s near-side hemisphere would have produced basins with as much as twice the diameter as similar impacts into cooler crust, which is indicative of early conditions on the moon’s far-side hemisphere,” stated lead author Katarina Miljkovic of the Paris Institute of Earth Physics (Institut de Physique du Globe de Paris).
As is common with research projects, learning more about the moon is revealing a new mystery that needs to be examined. It’s commonly cited that the moon was walloped during something called the late heavy bombardment, a period four billion years ago when it was believed that more meteorites impacted the moon.
“The late heavy bombardment is based largely on the ages of large near-side impact basins that are either within, or adjacent to the dark, lava-filled basins, or lunar maria, named Oceanus Procellarum and Mare Imbrium,” NASA stated.
“However, the special composition of the material on and below the surface of the near side implies that the temperatures beneath this region were not representative of the moon as a whole at the time of the late heavy bombardment. The difference in the temperature profiles would have caused scientists to overestimate the magnitude of the basin-forming impact bombardment.”
A research paper on the topic recently appeared in Science. GRAIL successfully concluded its mission last year after nine months of operations, flying into the side of a mountain as planned.
