Another blow was dealt to deep space exploration this past weekend. The announcement comes from Jim Green, NASA’s Planetary Science Division Director. The statement outlines some key changes in NASA’s radioisotope program, and will have implications for the future exploration of the outer solar system.

CORRECTION: This article has been updated after more information was received from Inspiration Mars. Tito was highlighting other countries’ interest in the Red Planet in his testimony and has no plans at this time to work with anyone but NASA.
Remember that proposal to send a couple in the direction of the Red Planet, loop around it and then come back to Earth? The founder of the Inspiration Mars project, Dennis Tito, outlined more details of his proposal before the House Science Subcommittee on Space yesterday (Nov. 20).
Inspiration Mars has released an Architecture Study Report that is the fruits of a 90-day study done not only by the foundation itself, but also working with “NASA centers and industry partners” to figure out the best way to launch humans there in late 2017 or 2018. But if it’s delayed, Tito is prepared to go to Russia or China instead, he warns.
Here’s the high-level summary:
Two launches using NASA’s forthcoming Space Launch System, one for cargo and one for crew;
The crew module would be from the crew transportation vehicle that NASA selected under its commercial crew program (see this Universe Today story yesterday for an update on funding concerns on that program);
The cargo and crew vehicles would dock in space and then head out to Mars.

“Given Russia’s clear recognition of the value and prestige of accomplishments in human space exploration, and their long-time interest in exploring Mars, my personal belief is that in all likelihood the Energia super-heavy rocket revival announcement signals Russian intent to fly this mission in 2021,” Tito stated.
“Their heavy lift rocket, along with their other designs for modules and the Soyuz, can fly this mission with modest upgrades to their systems.”
A third option would be using Chinese capabilities, he added, The Chinese may also be interested, he said, because the country — reportedly developing a large space station of its own — is likely “contemplating this opportunity to be the first on Mars.” Tito said he is informing Congress of his plans to go elsewhere as a “civic duty”, and that he wants to give NASA the first shot.
More food for thought as Congress mulls how much money to allocate to NASA in fiscal 2014. And Tito had strong words about his feelings on the funding: “If I may offer a frank word of caution to this subcommittee: The United States will carry out a Mars flyby mission, or we will watch as others do it – leaving us to applaud their skill and their daring.”
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.

There wasn’t a lot of elbow room when six people from the Endeavour shuttle floated into the baby International Space Station on Dec. 10, 1998, but the cramped quarters resonated with possibility in STS-88 commander Bob Cabana’s mind.
“It’s hard to believe 15 years ago we put those first modules together, and we have this facility today that’s the size of a football field,” said Cabana in an interview today (Nov. 20) with Universe Today.
Cabana, who is now the director of the Kennedy Space Center, oversaw a complex mission that included joining the Russian Zarya and U.S. Unity modules, three spacewalks to get the modules powered and ready for humans to enter, and the pressure of public relations activities surrounding the opening of the station itself.
“That was a very special day, when we went into Unity and Zarya for the first time. There was a lot of excitement and anticipation,” Cabana said. He and Russian Sergei Krikalev — who would go on to become the person who spent the most time in space, at 803 days — entered the tiny hatches side by side to emphasize the international participation.
As is typical of spaceflight, the astronauts spent most of their day at work, busily waking up the station and testing its systems. NASA astronauts Jerry Ross and James Newman put together a communications system. Other crew members tested the videoconference equipment — important for press conferences as well as talking to scientists on the ground. Equipment and supplies in Zarya had to be unstowed and organized.
There also was the first repair on station, when Krikalev and NASA astronaut Nancy Currie replaced a faulty unit in Zarya “which controlled the discharging of stored energy from one of the module’s six batteries,” NASA wrote in an update at the time.
Cabana wanted his crew to get eight hours of sleep, but the excitement of that first day kept everybody up until 2:30 in the morning despite the wakeup call coming at 7 a.m.

“We were talking about what the ISS means, what will be accomplished with this cornerstone,” Cabana recalled, and said he is pleased with what has come to pass in the next 15 years. “It had come true. Everything we thought that could be has come together. That was a very special night, thinking about the future and how important the International Space Station was.”
The heaviest construction finished in 2011, and larger crews of six were allowed on board rather than the beginning crews of just three. NASA is now trying to position the station as a venue for microgravity science to justify the expense of running it. The astronauts, however, must balance their time doing science with the normal chores and maintenance the station requires. (The recent Expedition 35/36 missions were extremely productive in terms of science return, NASA astronaut Chris Cassidy told Universe Today in a past interview.)
All buildings on Earth require upgrades from time to time to stay safe and up to date, and the ISS is no different. Cabana said analysis will be done to “extend the life on some of the modules, but we don’t see that as a large issue.” The reason? The crews do “an outstanding job” keeping the station humming along with routine maintenance, he said.
Today (Nov. 20) marks the 15th anniversary of Zarya’s launch into orbit. The station partners are currently committed until 2020, meaning negotiations are forthcoming to see what to do with the station in the years afterwards. It’s unclear what will happen next — the recession is still reverberating in the United States and overseas — but today, the agencies focused on the successes.
Each partner agency tweeted facts and science concerning the ISS under the hashtag #ISS15, and invited people using all forms of social media to share their thoughts on the station. What are some notable things about the station, and what is a good use of it in the future, in your opinion? Let us know in the comments.

Extreme conditions surround the International Space Station’s scientific work, to say the least. It takes a rocketship to get there. Construction required more than 1,000 hours of people using spacesuits. Astronauts must balance their scientific work with the need to repair stuff when it breaks (like an ammonia coolant leak this past spring.)
But amid these conditions, despite what could have been show-stoppers to construction such as the Columbia shuttle tragedy of 2003, and in the face of changing political priorities and funding from the many nations building the station, there the ISS orbits. Fully built, although more is being added every year. The first module (Zarya) launched into space 15 years ago tomorrow. Humans have been on board continuously since November 2000, an incredible 13 years.
The bulk of construction wrapped up in 2011, but the station is still growing and changing and producing science for the researchers sending experiments up there. Below are some of the milestones of construction in the past couple of decades. Did we miss something important? Let us know in the comments.

Talk about tiny technology. The NASA PhoneSat 2.4, which is set to launch today (Nov. 19), is so small that the satellite can easy fit in just one of your hands. The agency is quite excited about this second in the series of PhoneSat launches; the first, in April, saw three “smartphone satellites” working in orbit for a week.
PhoneSat is scheduled to launch as a hitchhiker aboard a rocket that will carry the U.S. Air Force Office of Responsive Space ORS-3 mission. The payloads will lift off from the Mid Atlantic Regional Spaceport at NASA’s Wallops Flight Facility in Virginia.
“It’s tabletop technology,” stated Andrew Petro, program executive for small spacecraft technology at NASA Headquarters in Washington.

“The size of a PhoneSat makes a big difference. You don’t need a building, just a room. Everything you need to do becomes easier and more portable. The scale of things just makes everything, in many ways, easier. It really unleashes a lot of opportunity for innovation.”
PhoneSat will be at a higher altitude than its predecessors, NASA added, allowing controllers to gather information on the radiation environment to see how well vital electronics would be affected. In the long run, the agency hopes these tiny machines can be used for Earth science or communications, among other things.
“For example, work is already underway on the Edison Demonstration of Smallsat Networks (EDSN) mission,” NASA stated. “The EDSN effort consists of a loose formation of eight identical cubesats in orbit, each able to cross-link communicate with each other to perform space weather monitoring duties.”
The launch is expected at 7:30 pm EST (12:30 a.m. UTC) and you can follow it on NASA TV.

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.

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.
