The interior of Russian space station Mir was not known for its pizazz — US astronaut Jerry Linenger called it “as drab as a Moscow winter” — and it ended up being crowded and cluttered with all sorts of unused equipment and old experiments. So, Mir was an unlikely place for an art exhibit … and perhaps why it was called an “art intervention” by one of the artists.
In the video above you can see a green “creature” floating freely in the Mir space station, — all angles and corners — gently brushing against spacesuits stashed in a corner. The video then shows it pivoting in the air, flashing red and green with people occasionally batting at it.
While the Russians were able to accept the angular sculpture, there were precautions to ensure that the paint would not produce toxic out-gasses or otherwise harm the astronauts, Woods added, saying the sculpture was even dunked in an alcohol solution prior to launch to remove any germs.
Then there was an entire art exhibition on station in 1995, called Ars Ad Astra. From 171 works submitted from all over the world, 20 were chosen for a ride into orbit with Thomas Reiter, a German astronaut. The crew then selected one to keep on display on the station, sending the rest of them back to Earth for exhibitions all over Europe.
The winner was “When Dreams Are Born”, an artwork from the United States’ Elisabeth Caroll Smith showing two children playing near a reflection of the moon in the water.
Information about the two art exhibits, which were co-ordinated by the Swiss O.U.R.S. Project, was displayed at the Canadian Space Society annual summit in Ottawa, Canada Nov. 14 to 15.
The International Space Station has also played host to several art projects, including this light show, a music video by Canadian astronaut Chris Hadfield, and dinosaur crafting from NASA astronaut Karen Nyberg, among others.

Here’s a handy tool. The folks at INOVE Space Modelshave just updated their awesome Comet ISON flyby simulation with a second point of view – how it looks from Earth. The first version let us watch from afar as ISON dives across across the solar system until it makes a hard left at the sun and returns to deep space. The new view lets you watch it track across the sky across from any location on Earth. Go to the link and toggle the Switch to Earth option in the upper left of the display and you’re off. The website attempts to automatically pinpoint where you are, but for me it was a tad off, selecting a town about 75 miles away. But a few miles this way or that make little difference given how far the comet is from Earth. If you need to make an adjustment, click the Location icon (upper right) and select your latitude and longitude.

You have two options for viewing. If you click the single arrow play button at the bottom of the screen, the display shows a horizon line with the stars, sun and comet rising and setting over a single day. In a day’s time the comet moves only a small distance in the sky, so it will appear in nearly the same spot the next day. Except around perihelion on Nov. 28. Then it moves so quickly – over 800,000 mph (1.3 million km) – fast enough to watch move hour by hour.
Besides just being plain cool to watch, the simulator is truly useful. The background star field shows constellation outlines and stars down to about 5th magnitude. Assuming the comet is reasonably bright, say 5th magnitude or brighter, you can use the simulations as locator maps now through the end of January. By clicking on the Time Box at upper right, you can set it to any time you like, grab a frame and head outside for a look.

Pressing the double arrow fast-forward button shows changes in position one day after another. To know what day you’re on just consult the timeline at the bottom of your screen. You can manually pull the time arrow to speed up, slow down or select a particular time of month. Other refinements are available in the Options box at upper left. Should you tire with Comet ISON from an earthly perspective, just click on Switch to Space at upper left and you’ll zoom back out for a solar system perspective. Enjoy the journey!
Another view of Comet ISON this morning photographed by Leonid Elenin
The un-simulated Comet ISON underwent a powerful outburst on Nov. 14 brightening by two magnitudes, as the two images here from Leonid Elenin and Scott MacNeil attest (and you can see more in our article from yesterday)
What had been a faint object in binoculars has become much more impressive. I caught it in my 10x50s in some small cracks between the clouds this morning (Nov. 15) and estimated its magnitude at 5.0. Had it been clear, I would have seen it with the naked eye. Through a 15-inch (37 cm) telescope at 64x the coma, now twice its pre-outburst diameter, glowed more blue than green with a dense core that looked like a bright, fuzzy star. Frankly, ISON was beautiful. Let’s hope this little outburst leads to better things to come and not early signs of the comet’s dissolution. Take a look yourself at the next opportunity and there might be a surprise waiting for you.

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
MAVEN is NASA’s next Mars orbiter and is due to blastoff on Nov. 18 from Cape Canaveral, Florida. It will study the evolution of the Red Planet’s atmosphere and climate. Universe Today visited MAVEN inside the clean room at the Kennedy Space Center. With solar panels unfurled, this is exactly how MAVEN looks when flying through space and circling Mars.

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.

Credit: NASA/Kim ShiflettBy 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 5,400 pound MAVEN probe carries nine sensors in three instrument suites.

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.
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.

Our friend Cory Schmitz planned the perfect time to go on a Iceland Aurora photo tour. With the recent activity from the Sun, there have been some great views of the aurora borealis in Iceland. “These images are very close to what the sky actually looked like to the naked eye,” Cory said on G+. “Motion, color, everything. Right above our heads. Insane — what an experience!”
Thanks for sharing the experience, Cory…. but next time, bring us with you, huh?

4 billion years ago, the atmosphere of Mars could have been rich in oxygen and thick enough and warm enough to support oceans of liquid water – a critical ingredient for life. A new animation from the Goddard Space Flight Center shows how the surface of Mars might have appeared during this ancient clement period. The artist’s concept video, below, is based on evidence that Mars was once very different and perhaps very Earth-like.
This past summer, a paper studying the compositions of Martian meteorites found on Earth and data from NASA’s rovers suggested that Mars had an oxygen-rich atmosphere very early in the history of the planet.
Scientists have long thought that the ancient riverbeds and what appear to be shorelines provide hints that Mars once supported oceans of water. But there’s not much indication of how the Red Planet was stripped of its thick atmosphere, roughly 3.7 billion years ago.
The end of the video shows the MAVEN spacecraft, the Mars Atmosphere and Volatile Evolution mission, orbiting Mars. This spacecraft is scheduled to launch on Nov. 18, 2013, and it will investigate how Mars lost its atmosphere. It should reach the planet in September 2014.
Below is another new video from NASA, featuring LeVar Burton talking about MAVEN.
Projected timeline of the MARS-X project. Credit: MARS-X
OTTAWA, CANADA – Humans would spend more than a year orbiting and bouncing on the Martian moon Phobos under a mission concept developed by students at the International Space University.
The very theoretical MARS-X mission — presented more as a concept than a firm plan — would see technology development taking place from 2018 to 2022, with communications satellites and rovers winging their way to the planet to be used by astronauts.
In 2023 to 2024, the spacecraft would be built in low-Earth orbit, requiring several launches to accomplish the massive task. Astronauts would then depart in 2024, spending eight months in transit before arriving at Phobos. There, the mission would last 495 days, and the astronauts would take five months to get home.
While NASA and Lockheed Martin helped sponsor the students who created the plan as part of their academic work, the concept itself is not yet funded beyond the students’ initial development.
But Piotr Murzionak, a member of the ISU team, said the proposal is one way that could help fuel interest in space exploration, if it was to be executed..
“It paves the way to Mars. It will be the initial step towards the landing mission on the Martian surface, but without the extra risk involved in order to land directly to Mars,” Murzionak said.

The Mars Exploration Vehicle (as the crew vehicle would be called) would use nuclear propulsion and liquid hydrogen to bring two habitats along with it. One of those would (along with several fuel tanks) be used on Phobos for up to 40 days of surface operations.
It would travel during solar maximum in 2024 to reduce the effects of cosmic radiation from outside the solar system, since the sun’s activity would blow the radiation further away. Further, the crew would be protected from solar flares with high-density polyethylene, as well as a temporary solar storm protection chamber lined with 50 centimeters of water.
The habitat would be spun at 4.4 revolutions per minute, with a habitat of 0.38 to 0.53 the force of gravity — about equivalent to what is on Mars. (This would take 2.5 metric tonnes of fuel to do.)
The students estimate this would cost about $20 billion, but it could go to at least double this due to factors such as “the volatility of political systems and the large amount of bureaucracy involved in any such endeavor,” they write in their final report, which is available here.
Murzionak presented the mission concept at the Canadian Space Society annual conference today (Nov. 14) in Ottawa, Canada.

OTTAWA, CANADA – With a booming voice, Walt Natynczyk — in his first speech after becoming Canadian Space Agency president in September — told delegates that he was happy to give up the “dream of retirement” to take on a challenging position.
“Imagine this picture. February. Saturday morning. 7 in the morning. It’s -25 [Celsius, -13 Fahrenheit] and I’m out there, by my lonesome, walking three dogs. None of which are mine. But their owners, who are family members, who I love, are all headed down south,” Natynczyk said.
“As I’m stooping over to pick up another pile of doggie doo, a neighbor — that I love — sticks her head out the door and says, ‘Hello, how the almighty have fallen.’ ” He paused as the room roared with laughter. “Think about it. That’s when I thought it was time to do something different.”
Natynczyk is best known in Canada for leading a large restructuring of the country’s military. He also was (as an exchange officer) a deputy commanding general in the United States, among other positions, and served in Baghdad at the height of the Iraqi war in 2004. His appointment to the CSA had some worried about the militarization of the agency. Natynczyk, however, focused on how difficult the new vocabulary is to master.
Speaking of a recent conversation with quantum researchers — the field that his predecessor, Steve MacLean, went into after leaving the CSA this year — Natynczyk said to them, “The point at which you start losing me is like talking to my puppy; when I start doing this,” — he tilted his head to one side — “you’re losing me.”
Joking that nanosatellites and microsatellites are equivalent to “milk cartons” and “milk jugs”, Natynczyk said one of his main goals is to make space understandable to the typical Canadian standing in line at Tim Horton’s, a coffee chain that is prolific in the country.
His comments on space policy were few. Last year, the Canadian government asked an external group to do a space development strategy for the country, and little has been mentioned publicly since the strategy was released. Natynczyk said conversations are ongoing with other government departments to address the recommendations.
Throughout, he stressed the importance of Canada’s choice to pursue research and development through the universities (with government support) rather than through government directly.
“It’s what we do with CSA, with the universities and so on, looking for extraordinary concepts that are in a higher-risk category and investing in a modest way — perhaps with other government funding … that allow for exponential jumps.”
Typical meteorological applications for the Polar Communications and Weather (PCW) mission. Credit: CSA.
OTTAWA, CANADA — A new Canadian satellite — should it launch — might carry a sort of magnetized force field on board to keep charged particles away from vital electronics.
The Polar Communications and Weather Satellite (PCW), depending on its orbit, could skim through the radiation-filled Van Allen belts on its mission to deliver reliable weather reports and communications to northern communities.
Its polar orbit will likely take it through clouds of charged particles high above Earth. If the particles hit crucial components on the spacecraft, it can short out electronics and cause brownouts or complete failure. This has happened several times before, such as to the Japanese ADEOS-II satellite after a large solar storm in 2003.
A concept being explored by Winnipeg’s Magellan Aerospace, one of the companies working on the early phase studies, would make a plasma field around PCW, a sort of “mini magnetosphere” that would use large dipole magnets to deflect charged particles.
It may also be useful for human missions in the future, said Paul Harrison, a satellite control systems engineer at Magellan Aerospace, although he acknowledged the technology is still in an early stage and that they would like a demonstrator mission to fly first.
“It’s still very much in the development phase. We want to develop for satellites before we start sticking people in them,” Harrison said in a presentation at the Canadian Space Society annual summit in Ottawa, Canada, today (Nov. 14.)
He also said it is not clear if the technology would be useful for cosmic rays that originate from outside the solar system, as well as charged particles that flow from the sun and are present near the Earth.
PCW has not been assigned a launch date yet and is still in the early stages of development. Other issues being explored include how to keep track of it without constant access to near-equator-orbiting GPS satellites, and how to maintain temperature control as it plunges from day to night to day again during its journey.
Its orbit could be a 12-hour Molniya orbit or perhaps a 16-hour or 24-hour highly eccentric orbit, depending on what designers feel is best.
CORRECTION: This article has been changed to say “near-equator-orbiting” GPS satellites.

After a sleepy week, Comet ISON is suddenly coming alive. Several amateur astronomers and at least one professional astronomers are reporting today that the comet has brightened at least a full magnitude overnight. Two days ago it glowed at around magnitude 7.5 and was visible weakly in 10×50 binoculars from a dark sky. Now it’s surged to around magnitude 5.5 – just above the naked eye limit – and continues to brighten. Several amateur astronomers have even seen it without optical aid.

ISON’s appearance has radically changed too. A week ago the comet developed a second gas or ion tail streaming alongside the wider, brighter dust tail. That new appendage has since grown like Pinocchio’s nose to nearly equal the length of the dust tail. I spotted it with averted vision Tuesday morning Nov. 12 through a 15-inch (37 cm) telescope. More exciting, the ISON’s head has been much brighter and more compact. Astronomers rate a comet’s degree of condensation or “DC” on a scale of 0 to 9 from extremely diffuse with no brightening in the center to disk-like or stellar. In recent days, Comet ISON has been packing it in at DC=6 or moderately compact and bright. Now amateurs are reporting that the comet’s head has brightened and become much more compact with a DC of 8.

Backing up reports of the outburst, astronomer Emmanuel Jehin of the TRAPPIST (TRAnsiting Planets and PlanetesImals Small Telescope) team, noted a tenfold increase in dust production around the comet’s nucleus on Nov. 11 and 12 plus additional jets of material blasting into the coma. Jehin reports that the inner coma near the nucleus is still very sharp and shows no sign of disruption – so far, ISON’s hanging in there.
If you haven’t seen the comet yet, you can use this map to track it through the weekend as it zips quickly through Virgo. The map shows the sky facing southeast just before the start of morning twilight or about 100 minutes before sunrise. ISON should be plainly visible in binoculars in a dark sky. Created with Chris Marriott’s SkyMap program
This is all great news for comet observers. The intense heat of the sun is beginning to boil away the comet’s ice with greater fury. The heat may also be exposing new cracks or breaks in ISON’s crust. Fresh ice means even more material becomes available for the sun to vaporize and likely additional jumps in brightness in the next day or two.
Trouble finding Virgo? Use this wide-view map to get oriented. Slide from Mars toward Spica near the southeastern horizon. ISON is about halfway between Spica and Gamma Virginis. The map shows the sky around 5-5:30 a.m. CST. Stellarium
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.)
