Pavlof Volcano From Station

Pavlof Volcano From Station

Astronauts aboard the International Space Station (ISS) photographed this striking view of Pavlof Volcano on May 18, 2013. The oblique perspective from the ISS reveals the three dimensional structure of the ash plume, which is often obscured by the top-down view of most remote sensing satellites.

Situated in the Aleutian Arc about 625 miles (1,000 kilometers) southwest of Anchorage, Pavlof began erupting on May 13, 2013. The volcano jetted lava into the air and spewed an ash cloud 20,000 feet (6,000 meters) high. When photograph ISS036-E-2105 (top) was taken, the space station was about 475 miles south-southeast of the volcano (49.1° North latitude, 157.4° West longitude). The volcanic plume extended southeastward over the North Pacific Ocean.

NASA tech chief takes to Reddit for a spacey ‘Ask Me Anything’ session

So, you want to know why the International Space Station dumped Windows in favor of Linux? Ask NASA chief technologist Mason Peck. He’s doing an “Ask Me Anything” thread on Reddit today, and he’s down to party.

Peck’s been in charge of NASA’s tech decisions since January 2012. He oversees the agency’s tech investments and also guides how future astronauts will use new innovations in missions to come. This means he has to work not only within the confines of government space programs, but he’s also working with commercial space companies and academic institutions.

Before you go asking him your questions, though, check out dude’s impressive background:

His research was sponsored by NASA’s Institute for Advanced Concepts, and one of his experiments currently lives aboard the International Space Station. He worked at Boeing, Honeywell, Northrop Grumman, Goodrich, Lockheed Martin, and Bell Helicopter, where he worked on the V-22 Osprey and a smaller tilt-rotor aircraft that later would become the BA609. He wrote 90 academic articles and holds 17 patents about space tech. And then he was a professor at Cornell. You know, like you do. No big.

So far on the thread, he says:

We need to create ways to help astronauts survive exposure to galactic cosmic rays and other hazards on the trip there and back. Getting there quicker would help. So that inspires the creation of advanced propulsion capabilities, but right now there’s nothing on the horizon to shorten the trip time enough so that we don’t have to worry about radiation.

I’m very excited by the prospect of citizen space, that is, individuals building their own space technology and launching it. Some incredible innovations come from the do-it-yourself or maker community, and I expect the renaissance in technology that makers represent will have a big impact on NASA’s future.

Right now, we’re working on the technologies that will get humans to an asteroid by 2025 and on to Mars in the 2030s. Some of those technologies include propulsion and navigation, but also technologies to protect astronauts from radiation on the trip there and back. Some day, the earliest explorers of the outer solar system and beyond will be robotic spacecraft, some may be as small as smart phones.

NASA: New Pump Resolves Big Space Station Leak

AP Photo/NASA

In this Saturday, May 11, 2013 photo made available by NASA, astronaut Chris Cassidy and Tom Marshburn, not pictured, perform a space walk to inspect and replace a pump controller box on the International Space Station after an ammonia coolant leak was discovered.

CAPE CANAVERAL, Fla. — An impromptu spacewalk over the weekend seems to have fixed a big ammonia leak at the International Space Station, NASA said Thursday.

The “gusher” erupted a week ago, prompting the hastiest repair job ever by residents of the orbiting lab. Spacewalking astronauts replaced a suspect ammonia pump on Saturday, just two days after the trouble arose.

NASA is now calling the old, removed pump “Mr. Leaky,” said flight controller Anthony Vareha.

“Right now, we’re feeling pretty good. We definitely got the big leak,” Vareha said in a NASA broadcast from Mission Control in Houston.

Vareha said engineers don’t know whether the pump replacement also took care of a smaller leak that has plagued the system for years. It will take at least a couple months of monitoring to know the full status.

Ammonia is used as a coolant in the space station’s radiator system.

The leak forced one of the station’s seven power channels to go offline. NASA hopes to resume normal operations early next week, following computer software updates.

One of the spacewalkers, NASA astronaut Thomas Marshburn, is now back on Earth. He returned this week aboard a Russian Soyuz capsule, ending a five-month mission.

The other spacewalker, Christopher Cassidy, a recent arrival, spent Thursday chatting with three of the actors and a writer-producer of the newest Star Trek movie, “Star Trek into Darkness.” The film was beamed up to the space station a few days before its U.S. opening in theaters Thursday.

Cassidy watched the first half-hour of the movie while he was exercising Thursday morning and offered a stellar review.

“I was riveted as you’re racing through the woods and jumping off cliffs,” he told the actors. “I won’t spoil the rest of the movie for anybody who hasn’t seen it. But pretty cool scenes.”

Why NASA doesn’t have a Chris Hadfield – Washington Post


<!–

–>



submit to reddit

Canadian astronaut Chris Hadfield produced a stunning music video tribute to David Bowie’s “Space Oddity” aboard the International Space Station before returning to Earth this week. It’s a genuine Internet hit with an awesome backdrop to boot.

Hadfield, 53, combined his social media popularity, the skills of his Web-savvy son, Evan, and the full support of the Canadian Space Agency to shoot and produce a video seen in recent days by more than 7 million people.

I first watched the video Monday morning and a bad feeling set in almost immediately: The modern-day ways of Washington — its intense focus on budget cutting and no tolerance for the misbehavior or poor management of career civil servants — mean that a NASA astronaut wouldn’t dare try something like this.

Let’s game out how things might play out if an American astronaut had shot a music video in space.

The astronaut, with a knack for guitar playing, is preparing to leave the International Space Station and transfer command to another passenger. Inspired by his trip, he reaches out to agency officials back on Earth and pitches them the idea of shooting a musical tribute (that’s what Hadfield did). Interested, his colleagues back on terra firma help him produce the film. NASA releases it shortly before his departure, it is seen by millions of viewers and initially earns the space agency plaudits for creativity and for reminding people of America’s place in space.

But then a lawmaker — of either party — starts raising questions: Why did this astronaut waste his time shooting amateur video in space? Is this why we send Americans to the ISS? Shouldn’t he be focused on more serious scientific experiments? What types of experiments is he conducting anyway — and do they really serve a benefit worthy of taxpayer expense?

Reporters eager to keep the story going pick up the lawmaker’s concerns and start asking questions of NASA officials. Over the course of a few days, the story balloons into a bigger controversy and the agency eventually apologizes.

But it doesn’t stop there: The lawmaker, enjoying all the attention he’s earned for raising questions, calls for hearings or an inspector general investigation. Hearings are held, a report is issued and NASA suffers from an embarrassing distraction, all because an astronaut wanted to pay tribute to his time in space and hopefully inspire others to pursue his line of work.

Don’t forget, NASA wakes up the astronauts most mornings by playing them a favorite song and a group of NASA employees produced a spoof of the song, “I’m Sexy and I Know It” last summer called, “We’re NASA and We Know It.” Several U.S. military units videotaped themselves lip-synching to Lady Gaga in amateur music videos shot on the battlefields of Iraq and Afghanistan — while a soldier earned plaudits for posting video shot from his helmet cam that recorded him coming under fire.

But most government employees wouldn’t dare try such a thing. On my former beat covering federal agencies, I heard often from career government employees distressed that brash partisanship in Congress and the government’s mounting debt were stifling creativity, ambition and any hope of government lawyers, engineers, researchers — and yes, astronauts — remaining ahead of the curve or on the cutting edge. They also lamented that attempts to have a little fun promoting their work could be seen as going too far by bosses nervous of angry congressional reaction.

Could an American astronaut do what Hadfield did? Surely. But do you think they’d dare try? Considering how things are in Washington right now, probably not.

First quilter in space: NASA astronaut plans to turn orbital rags to stitches

NASA

NASA astronaut (and quilter) Karen Nyberg looks out the window of the Japanese Kibo laboratory on the International Space Station in 2008.

When astronaut Karen Nyberg is launched to the International Space Station, she’ll bring something entirely new to the space frontier: the art of quilting.

“I enjoy sewing and quilting,” she explained during a televised interview from Moscow. “I am bringing some fabric with me, and thread. I’m hoping to create something. I don’t know what yet it will be — that’s part of creativity. It comes with the feeling of the day. So I have the supplies at my hands to create, if I get the opportunity and the creative notion to do so.”


When she’s launched into space on May 28, she’ll be taking four “fat quarters” with her (pieces of fabric that are 18 by 22 inches), along with some needles and thread. But up-cargo limitations and safety issues mean she can’t take a sewing machine, an iron, paints, a rotary cutter or other common tools of quilters.

Stitching in zero-G
To do quilting in zero gravity, she’ll have to brace herself somewhere so she and her fabrics don’t float around, find some good light, and keep her thread and thread clippings under strict control so they don’t float into someone’s face and eyes.

Precision stitching will surely be a challenge for her too, since she, the fabric, and the thread will want to float free, not sit steady and still. As she explained in a recent tweet, “It will be great experiment controlling everything!”

K. Nyberg / NASA

Karen Nyberg created this quilt for her niece.

Though she’s limited in the material and equipment she can bring into space, Nyberg can use fabric or patches from the discarded astronaut clothing already on board the space station — some of it quite colorful. As a rule, the space station crew members wear a flight suit for a week and then discard it. There are no laundry facilities aboard the space station, so the uniforms are generally added to the trash heap that builds up inside a Russian Progress resupply ship after it is emptied. Eventually, the Progress is jettisoned, and everything in it burns up in Earth’s atmosphere.

The issue of obtaining sewing scraps from a readily available “rag bag” in orbit first came up in a face-to-face interview in Houston last month. She broke into a broad, excited smile: “Discarded clothing — fantastic idea!”

And although paints and dyes are forbidden on the space station, Nyberg pointed out that there are condiments aboard that can take their place, which might be used as decoration — ketchup, mustard and chili sauce can make for some interesting painting materials.

Down to Earth
The first quilt in space would be an exciting, unique and valuable item. Bringing a quilt back to Earth might be a problem, since Nyberg has a limited space allotment in the Soyuz capsule she’ll be traveling in next November. But she hopes to bring at least some of her handiwork back with her.

Fortunately, there may be additional opportunities to bring her space handiwork down to Earth. Unmanned SpaceX Dragon cargo capsules are carrying supplies up to the space station, with the next flight scheduled in November. The Dragon has a large volume for returning cargo to Earth, and NASA and SpaceX should be able to find room for a quilt or two.

If Nyberg has access to a cosmic rag bag of discarded uniforms from many countries — the United States, Russia, Canada, Italy, Japan and others — think of what her fellow quilters back on Earth could do with such star-struck materials.  NASA could decide to recycle space-flown uniforms back to Earth someday, and distribute them to quilters as part of a citizen outreach project.

The International Space Station itself is already a patchwork quilt of hardware: equipment, life support systems and structural elements that have been fabricated in various nations and pieced together over more than a decade. As with quilting, the station’s life support systems emphasize recycling and re-use.

Nyberg has not mentioned any designs for her quilts. She said that she’s “counting on creativity when I get there.”  She has a sketch pad, a pencil and a pencil sharpener to draw out the ideas that come to her. Whether it follows a traditional design, or a new look dictated by cosmic imagination, whether it’s simple or fancy, the first quilt in space will undoubtedly become one of those precious images we’ll have sewn into our culture.

More about space crafts:


NBC News space analyst James Oberg spent 22 years at NASA’s Johnson Space Center as a Mission Control operator and an orbital designer. Alcestis Oberg is a science writer and quilt collector. The Obergs are co-authors of “Pioneering Space: Living on the Next Frontier.”
