Is A Sitcom Astronaut Hadfield’s Next Frontier? ABC Comedy In The Works, Report Says

It’s possible that Chris Hadfield’s best-selling book will become a sitcom! The astronaut who quickly became the world’s most-wanted Canadian last year, based on his amusing YouTube videos and stunning space pictures, is involved in production of a sitcom based on An Astronaut’s Guide To Life On Earth, Deadline reports.

“The TV series is described as a family comedy about an astronaut who is back from space and finds that re-entering domestic life might be the hardest mission he’s ever faced,” wrote Deadline. Hadfield is slated to be the consulting producer on the show, which has been approved for pilot production.

Hadfield made headlines during his third and final spaceflight in 2012-13, part of which saw him was commander of the International Space Station’s Expedition 35. His five-month flight in space saw his Twitter numbers soar as he virtually hobnobbed with celebrities and worked social media every day, with the help of his son Evan. (This was done in between running one of the most scientifically productive missions on the station ever.)

Weeks after returning to Earth, Hadfield retired from the Canadian Space Agency. His second book, You Are Here: Around the World in 92 Minutes, is expected to be released in October.

Space is a serious business, but there are some comedies associated with it. Former NASA astronaut Mike Massimino has been a repeat guest on The Big Bang Theory, particularly when one of the main characters went into space. NBC is also working on a sitcom called Mission Controlwhich describes the challenges of a female aerospace engineer trying to make her way in the male-dominated field of the 1960s.

ABC also is taking space to a more serious side, as it is expected to make a miniseries based on the Lily Koppel bestseller The Astronaut Wives Club — a look at the wives of the first astronauts in the 1960s.

Last Chance: Hadfield’s ‘Space Oddity’ Video Coming Down Soon

After one turn around the sun, it’s time for Chris Hadfield’s ultimate space music video to go to that great graveyard in the sky.

The astronaut tweeted earlier today (May 13) that singer David Bowie gave permission for Hadfield’s “Space Oddity” to be online for a year, and that the video is coming down today. So be sure to watch on YouTube above while you have the chance.

Update (6/25/14): A clarification on this story. The Ottawa Citizen newspaper clarified that it wasn’t David Bowie that only gave a year’s use of the song: “Space Oddity was the only one of more than 300 songs he has written and recorded for which he did not own or control the copyright. Mr. Bowie offered to have his people call the publisher and convey his strong support, but he had no ability to personally dictate any of the terms of the license or even require the publishers to issue one.”

Hadfield also tweeted today that ” Our Oddity will be back online soon.” We’ll repost it when it becomes available.

The Canadian’s homage to Bowie — with slightly altered lyrics — garnered more than 22.4 million views as of this morning, Eastern time. It was filmed on board the International Space Station and produced by Hadfield’s son, Evan. Music was recorded on Earth.

The video capped five months of intense public outreach that Hadfield did during Expedition 34/35 in 2012-13. During Expedition 35, he was the first Canadian commander on station, but still found time to record videos and music showcasing his time in space.

Since returning to Earth, Hadfield has already penned one best-selling book — An Astronaut’s Guide To Life On Earth — and is now working on a second that will include photos from his mission.

You’re In A Spacesuit, Blind. This Astronaut Survived It And Explains What He Did Next

“There is no problem so bad that you can’t make it worse.” So with that old astronaut principle in mind, what is the best reaction to take when your eyes become blinded while you’re working on the International Space Station, in no more protection than with a spacesuit?

The always eloquent Canadian (retired) astronaut Chris Hadfield — commander of Expedition 35 — faced this situation in 2001. He explains the best antidotes to fear: knowledge, practice and understanding. And in this TED talk uploaded this week, he illustrates how to conquer some dangers in space with the simple analogy of walking into a spiderweb.

Say you’re terrified of spiders, worried that one is going to poison you and kill you. The first best thing to do is look at the statistics, Hadfield said. In British Columbia (where the talk was held), there is only one poisonous spider among hundreds. In space, the odds are grimmer: a 1 in 9 chance of catastrophic failure in the first five shuttle flights, and something like 1 in 38 when Hadfield took his first shuttle flight in 1995 to visit the space shuttle Mir.

So how do you deal with the odds? For spiders, control the fear, walk through spiderwebs as long as you see there’s nothing poisonous lurking. For space? “We don’t practice things going right, but we practice things going wrong, all the time so you are always walking through those spiderwebs,” Hadfield said.

And then he tells the tale of his 2001 spacewalk during STS-100 when he was outside, blinded by a substance in his helmet, trying to work through the problem. (The incident has even more resonance today, just a few months after an Italian astronaut had a life-threatening water leak in his NASA spacesuit.)

Be sure to watch the talk to the end, as Hadfield has a treat for the audience. And as always, listening to Hadfield’s descriptions of space is a joy: “A self propelled art gallery of fantastic changing beauty that is the world itself,” is among the more memorable phrases of the talk.

TED, a non-profit that bills itself as one that spreads ideas, charged a hefty delegate fee for attendees at this meeting (reported at $7,500 each) but did free livestreaming at several venues in the Vancouver area. It also makes its talks available on the web for free.

Hadfield rocketed to worldwide fame last year after doing extensive social media and several concerts from orbit.

Robots And Astronauts Feature In First Glimpse of Canada’s New Space Policy

About six years ago, the Canadarm — Canada’s iconic robotic arm used in space — was almost sold to a company in the United States, along with other space technology from MacDonald, Dettwiler and Associates. The Canadian government blocked the sale and swiftly came out with a promise: a space policy to better support Canada’s industry.

That promise was made in September 2008. “Time is of the essence,” then-Industry Minister Jim Prentice told reporters upon announcing a space policy would be created. Today, 65 months later, the government released the high-level framework of that policy. Astronauts, telescopes and yes, the Canadarm are all prominently mentioned in there.

A lot has happened in six years. Policy-makers used to cite successor Canadarm2’s role in space station construction. Now the arm also does things that were barely imaginable in 2008 — namely, berthing commercial spacecraft such as SpaceX’s Dragon at the International Space Station. It shows how quickly space technology can change in half a decade.

At 13 pages, there isn’t a lot of information in Canada’s framework yet to talk about, but there are some statements about government priorities. Keep the astronaut program going (which is great news after the success of Chris Hadfield). A heavy emphasis on private sector collaboration. And a promise to keep funding Canada’s contribution to the James Webb Space Telescope, NASA’s next large observatory in space.

These are the Top 5 priorities listed in the plan:

  • Canada First: Serving Canada’s interests of “sovereignty, security and prosperity.” As an example: The country has a huge land-mass that is sparsely populated, so satellites are regularly used to see what ship and other activity is going on in the territories. This is a big reason why the Radarsat Constellation of satellites is launching in 2018.
  • Working together globally: Canada has a tiny space budget ($488.7 million in 2013-14, $435.2 million in 2014-15 and $382.9 million in 2015-16), so it relies on other countries to get its payloads, astronauts and satellites into space. This section also refers to Canada’s commitment to the International Space Station, which (as with other nations) extends to at least 2024. That’s good news for astronauts Jeremy Hansen and David Saint-Jacques, who are waiting for their first trip there.
  • Promoting Canadian innovation: The James Webb Telescope (to which Canada is contributing optics and a guidance system) is specifically cited here along with the Canadarm. Priority areas are Canada’s historic strengths of robotics, optics, satellite communications, and space-based radar, as well as “areas of emerging expertise.”
  • Inspiring Canadians: Basically a statement saying that the government will “recruit, and retain highly qualified personnel,” which in more real terms means that it will need to keep supporting Canadian space companies financially through contracts, for example, to make this happen.

That last point in particular seemed to resonate with at least one industry group.

“A long-term strategic plan for Canada’s space program is critical for our industry. In order to effectively invest in innovation, technology and product development, we rely heavily on knowing what the government’s priorities for the space program are,” stated Jim Quick, president of the Aerospace Industries Association of Canada (a major group that represents the interests of private space companies.)

While we wait for more details to come out, here’s some valuable background reading. The space-based volume of the Emerson Report (the findings of a government-appointed aerospace review board listed in 2012) called for more money for and more stable funding of the Canadian Space Agency, among other recommendations.

And here’s the government’s point-by-point response in late 2013. In response to funding: “The CSA’s total funding will remain unchanged and at current levels. The government will also leverage existing programs to better support the space industry.” Additionally, the CSA’s space technologies development program will be doubled to $20 million annually by 2015-16, which is still below the Emerson report’s recommendation of adding $10 million for each of the next three years.

Chris Hadfield Launched Into Space One Year Ago Today

And we have liftoff … for a social media sensation! Canadian astronaut Chris Hadfield rocketed into orbit a year ago today (Dec. 19, 2012) accompanied by NASA astronaut Tom Marshburn and Russian cosmonaut  Roman Romanenko.

Hadfield was a part of the Expedition 34 crew, then took command of the station during Expedition 35 in early 2013. While running an extremely productive science mission, he did tons of public outreach, ranging from singing to humorous space-y how-to videos to chatting with numerous celebrities before landing in May.

The Canadian Space Agency invited folks on Twitter to share their reflections under the hashtag #hadfield1yr, which is already producing a lot of thoughtful responses (a few of which you can see below the jump). What was your favorite part of the mission? Feel free to share in the comments.

While Hadfield is retired as an astronaut, he remains very busy. He’s in the middle of a multi-country book tour and will begin teaching at the University of Waterloo in Ontario, Canada in fall 2014.

Astronauts Get Three Spacewalks As An Early Christmas Present

The week before Christmas will be full of spacewalk preparations for Expedition 38 as they get ready to remove and replace a malfunctioning pump aboard the International Space Station.

NASA astronauts Rick Mastracchio and Mike Hopkins will participate in the spacewalks, NASA said today (Dec. 17), with Japanese astronaut Koichi Wakata handling robotic operations during the Dec. 21, Dec. 23 and Dec. 25 activities.

A new pump is needed to regulate temperatures in an external ammonia cooling loop that shut down automatically Wednesday (Dec. 11) when it got too cold. The loop keeps equipment at the right temperature on station. While the astronauts have been fine for the past week, several redundant systems and some experiments are offline. Luckily for the crew, other astronauts previously installed three spare pumps on station, which you can see in the graphic below.

Spacewalks are always a risky proposition, and NASA has not conducted any since Italian astronaut Luca Parmitano experienced a leak in an American spacesuit in July. As such, the agency spent several days trying to fix the cooling loop by other means.

A faulty control valve made the pump malfunction on Wednesday. The valve normally mixes warm ammonia that flows past external radiators on station with cooler ammonia that was put through those radiators. NASA first tried to control the valve from the ground, then focused its attention on an isolation control valve upstream from the pump that the agency hoped could serve as a backup. The isolation valve, however, was only designed to be closed or opened fully — not positioned in between.

As of 11 a.m. EST (4 p.m. UTC) today, NASA was working on a software patch to try to freeze the valve in different positions to manually regulate the flow of ammonia.

“The fidelity that we have here on the ground to precisely control when that valve starts moving and stops is on the order of about 0.2 seconds, 0.3 seconds, somewhere in that range. We really need the fidelity to be much higher than that,” said Judd Frieling, the Expedition 38 lead flight director, in an update on NASA Television.

“We need it to be on the order of 0.1 seconds. So the way we can reliably produce that is by putting some software on the computers on board that basically allows us to get that finer control. So engineers and coders, overnight, have been working on a software — we call it a patch — software fix, to one of the computers that controls that valve.”

NASA planned to upload the patch to the station this afternoon (EST) to see if it was possible to control the isolation valve by telling it to move, then cutting the power when it got to a certain spot. The agency did not say how successful that fix was, but will likely address that in a media briefing tomorrow at 3 p.m. EST (8 p.m. UTC).

Cooling problems have occurred on station before. The most recent failure was a leak in May, which the Expedition 35 crew fixed just days before some of the astronauts went home. A more prominent failure on the same cooling loop occurred in 2010, when Expedition 24 astronauts performed three spacewalks to replace a faulty pump.

Each of the three emergency spacewalks this month (Dec. 21, 23 and 25) will start at 7:10 a.m. EST (12:10 p.m. UTC) and take about 6.5 hours to perform, NASA added. The activities will be carried live on NASA Television, with coverage starting about an hour before each spacewalk is expected to begin.

UPDATE: NASA Pushes Back Cygnus Launch Decision Due To Space Station Cooling Problem

The decision to launch a cargo flight to the International Space Station next week has been pushed back until Monday (Dec. 16) because of a cooling problem on station that forced the shutdown of redundant systems, according to a NASA update.

Orbital Sciences’ Cygnus commercial spacecraft is expected to blast off on Dec. 18 from the Wallops Flight Facility in Virginia. However, with some station systems offline, the launch does not now meet certain “commit criteria” to make its journey to space next week, said Kenny Todd, the space station’s mission integration and operations manager.

“We haven’t lost any primary functionality,” he said in a NASA Television update today (Dec. 12), emphasizing that the six-person Expedition 38 crew is fine. “There is some redundancy that we’re down right now, but that’s not something I would call critical to day-to-day station operations.”

While a spacewalk is a possibility to fix the problem, it’s too early to say what NASA and other space station partners will decide to do.

NASA controllers spent the night examining a control valve blamed for causing an ammonia pump to shut down yesterday (Dec. 12). The space station uses liquid ammonia to maintain its temperature, pumping the ammonia through external radiators to bleed off heat. Astronauts have made periodic spacewalks to repair parts of the ammonia system, most recently in May when Expedition 35 replaced a pump controller box on the P6 (far port) truss just days before some crew members went home.

“The pump module on one of ISS two external cooling loops automatically shut down today when it got too cold,” stated the NASA Johnson Space Center Twitter feed yesterday (Dec. 11).

“The pump was brought back online, but they think a valve may not be working correctly inside it. Some of the station’s internal electrical systems were moved over to the second loop, and some noncritical things were powered down. The crew was always safe and will work with the ground teams as they figure out what caused the issue.”

Non-critical systems were powered down in the Harmony node, Columbus Laboratory and Japanese Kibo laboratory. After confirming that the new configuration was stable, controllers began this morning (EST) to move the troublesome valve to several positions and monitor the effect on cooling temperatures, according to a NASA TV update.

The crew is going about their activities as much as possible, although they’re on a “reduced timeline” because some of the experiments aren’t running as usual. (Science collected up to now is “not at risk”, Todd said.)

Responding to questions on social media, NASA astronaut Douglas Wheelock — who led three unplanned spacewalks in 2010 to replace a broken ammonia pump module on the S1 truss in the same cooling loop — said he is working with Mission Control to see what needs to be done next.

Of note, NASA has suspended spacewalks after a water leak in one of its spacesuits forced Italian astronaut Luca Parmitano back to the airlock during work in July. (Crewmate Chris Cassidy, who was on the spacewalk at the same time, later said he felt Parmitano was in no immediate danger, but felt the prudent thing to do was stop.)

Astronauts have been troubleshooting the suit periodically on board station, but NASA is planning to send it back on the next SpaceX Dragon flight to Earth for further investigation. SpaceX isn’t planning to get to the station again until late February, media reports say. Russian spacewalks can still continue as they use a separate suit; the most recent one took place in November with the Olympic torch.

While Todd didn’t quite say the ban on spacewalks has been lifted, he added that NASA has new procedures in place to guard against another crew member facing the same water issue. He did not elaborate on what those procedures are.

The current launch window for Cygnus extends as far as Dec. 21 and “possibly” the 22nd, Todd said, but emphasized more time is needed to come to a decision. “At this point, for lack of a better term, we’re going to kick the can a little bit and let the team work a little bit more,” he said.

Updates will follow as the situation and fix progresses.

Chris Hadfield On Space-y $5 Bill: ‘It Reminds Us That Our Dreams Do Not Have A Limit’

In Canada, “gimme five” could soon have a space connotation. Today the country announced it is preparing to put new polymer $5 bills into circulation that feature Canadian robotics and an astronaut.

At the official circulation ceremony near Montreal, Que. was none other than Canadian astronaut Chris Hadfield, who brought unprecedented social media attention to space through social media. The world was enchanted by his guitar playing and crying in space, but in space circles he also commands a lot of respect. The trilingual Hadfield visited two space stations, helped build the robotic Canadarm2 in space, and commanded the International Space Station, among other achievements.

His presence was appropriate, because the $5 bill has a lot of robotics on it. Canadarm2, Dextre and an astronaut are splashed across one face of the bill. “It reminds us that our dreams do not have a limit,” Hadfield said in French.

“It serves as a reminder to all Canadians of the dedication and hard work of so many people across the Canadian Space Agency and the space industry across Canada, and the scientists and engineers that make the design of these incredibly complex robots and getting them into space somehow easy,” Hadfield added in English. “Being involved in it is the real inspiration part. Who knows where such innovation can take us.”

The Bank of Canada first unveiled the new $5 and $10 bills in April, while Hadfield was at the helm of the station. Canada’s central banking authority is touting the new plasticized bill series as more durable than past cotton-based ones, with better counterfeit measures such as transparency. Polymer bills are available already in $20, $50 and $100 denominations.

Opposite to the space-themed side of the $5 bill is a picture of past prime minister Wilfrid Laurier. The new $10 bill features a train on one side and (as with the past iteration) John A. Macdonald, the first Canadian prime minister, on the other.

Hadfield himself has featured on both Canadian currency and stamps in the past: the Royal Mint of Canada issued two coins with him and Canadarm2 in 2006, and Hadfield was among several astronauts put on to Canadian stamps in 2003.

Chris Hadfield Regretted Not Being Able To Make One Last Spacewalk

Chris Hadfield loved spacewalking. That was clear in a past interview he did for Universe Today:

It is like coming around a corner and seeing the most magnificent sunset of your life, from one horizon to the other where it looks like the whole sky is on fire and there are all those colors, and the sun’s rays look like some great painting up over your head. You just want to open your eyes wide and try to look around at the image, and just try and soak it up. It’s like that all the time. Or maybe the most beautiful music just filling your soul. Or seeing an absolutely gorgeous person where you can’t just help but stare. It’s like that all the time.

Late in Hadfield’s final mission to space this May, when the Canadian Space Agency (CSA) astronaut was commanding the International Space Station Expedition 35 crew, an ammonia leak happened and NASA had to scramble a plan for a spacewalk, or extravehicular activity (EVA), to fix it. (The fix succeeded.) When Hadfield was apprised of the plan, he says in an excerpt from his forthcoming book, he was disappointed:

I wasn’t going out. I had a moment where I allowed myself to experience the full force of my disappointment. This would have been the heroic climax of my stint as commander: helping to save the ISS by doing an emergency spacewalk. I’d never have another chance to do an EVA—I’d already informed the CSA that I planned to retire shortly after returning to Earth.

But Chris [Cassidy] and Tom [Marshburn] had both done three previous EVAs, two of them together, on the same part of the station where ammonia was now leaking. They were the obvious people for the job. All this went through my head and heart for a minute or two, then I made a resolution: I was not going to hint that I’d had this pang of envy, or say, even once, that I wished I was doing the EVA. The right call had been made, and I needed to accept it and move on so that we could all focus on the main thing—the only thing, really: working the problem.

An Astronaut’s Guide to Live On Earth isn’t out until Nov. 3, but Maclean’s magazine has a lengthy excerpt that not only talks about the spacewalk, but some behind-the-scenes discussion on Hadfield’s awe-inspiring version of David Bowie’s “Space Oddity” recorded on the International Space Station.

‘I Didn’t Think He Would Drown’: Spacewalking Crewmember on Spacesuit Leak

Safely back on Earth on Sept. 10, astronaut Chris Cassidy happily chatters about his daily trips to the gym — “I feel real solid with my walking”, he says — and cracks one-liners during one of a series of media interviews on Thursday.

“It was such a treat being up there with [Chris] Hadfield, and I think I need to get credit for filming some of those videos,” joked Cassidy in a phone interview from Houston with Universe Today. His favorite video with Canada’s Expedition 35 commander? A remake of David Bowie’s Space Oddity that got props from Bowie himself.

Cassidy’s half-year voyage in space was full of these light moments, such as his decision to shave his head in homage to his bald crewmate, Luca Parmitano, who arrived on the International Space Station as a part of Expedition 36 on May 29. Weeks later, however, the men’s mood turned serious during a July 16 spacewalk; Parmitano reported water pooling at the back of his head.

“I was watching out when we were face to face outside,” Cassidy said. “Once it got onto his eyebrow hair area, it whipped across the top of his forehead and then sort of slid around his eyeballs. It migrates from hair to hair, and the little wispy hairs around your eyes, kind of, and then it travelled towards his eyelids and eyelashes. That was the scary part.”

Cassidy is a former Navy SEAL who passed, first try, the grueling “hell week” all recruits go through. In 5.5 days, SEAL trainees get just four hours of rack time while having to move for up to 200 miles. A veteran of shuttle mission STS-127, Cassidy also accumulated more than 18 hours of spacewalking experience across three excursions. All of his knowledge was brought to bear as he watched the water travelling across Parmitano’s head.

“From my experience in the military, I know bad things don’t get better fast, but they get worse fast. I wanted to get as quickly to the airlock as we could,” Cassidy said. NASA prudently ended the spacewalk and told Parmitano to head back to the hatch. Cassidy quickly did a cleanup at the work site and followed Parmitano.

“When we left each other at the work site and we had to go our separate ways back, at first I wasn’t too concerned,” Cassidy said. “And then when we left each other, the sun set. It was dark. His comm was going in and out and I could tell from his voice he was getting less and less comfortable … He didn’t have a whole lot of EVA experience, and it was nighttime, which is significant. It was pitch dark. You just have to know your way back, and he couldn’t see that well.”

Back in the hatch, Cassidy and Parmitano communicated through hand squeezes as the water was soaking Parmitano’s communications system. Cassidy carefully watched Parmitano’s mouth to see if the water was getting near there.

“I didn’t think he would drown, to be honest … but if it got close to his mouth I was going to immediately open the valve that equalizes pressure [inside the hatch.]” Cassidy added that usually, NASA goes slow during repressurization for ear safety and some technical reasons, but in this case he was prepared to flood the compartment if necessary. But it wasn’t. The rest of the crew then opened the hatch and got Parmitano out of his spacesuit as quickly as they could.

“Just from a human interest point of view, it was a lot of water,” Cassidy said. “When you try to describe an amount of water it’s difficult to put it in terms that people get it. But it was definitely more than a softball or two softballs of water inside the helmet.”

You can read Parmitano’s blogged account of the spacewalk here. The astronaut is currently unavailable for interviews while he is in orbit, the European Space Agency told Universe Today. NASA is still investigating the cause — the agency, in fact, also has a parallel investigation to look at spacewalk safety procedures in general. Cassidy attempted to change a filter and do other repairs in orbit, but the leak still happened, as these videos show. More detailed analysis will happen when the spacesuit goes back to Earth on a future SpaceX Dragon cargo flight, Cassidy said.

Cassidy also performed an emergency spacewalk in May when a coolant leak was discovered on the station itself as Hadfield’s Expedition 35 crew was set to return home. In just days — a typical spacewalk takes at least months to plan — NASA swiftly implemented a successful fix. Cassidy said his work was the easiest bit of all. “All I had to do was go out there and change the pump,” he said.

Despite the mishaps, however, science productivity on the station has reached a high when compared to maintenance activities. Expedition 35 reportedly had the most productive science mission to date, and Cassidy said Expedition 36 will likely show similar results. “We had a real nice successful six month stretch there where things were just working, and that allowed us to do a lot of science,” Cassidy said. One experiment involved playing with rovers.

Cassidy, Parmitano and Karen Nyberg each took turns operating the K10 rover prototype, a NASA Ames Research Center project. The goal is to simulate how astronauts could control a rover on an asteroid, the moon or Mars rather than heading down to the surface themselves.

“That was really cool to know we were on the space station, flying around the planet, with this actual real thing in California moving around,” Cassidy said. “It was more testing of what user interfaces are most intuitive and most useful for this kind of application … and in my opinion they pretty much nailed it, it was so intuitive.”

Now back on Earth, Cassidy said he generally feels great from a health perspective. His first set of exercises came about an hour after landing. He was carried into a medical tent and asked to do a quick series: sit in a chair and then stand up for 10 seconds. Lie on the ground for about a minute, then try standing for three minutes.

“My legs got wobbly for fatigue. They weren’t used to holding that weight,” Cassidy said, but observed that he readjusted to Earth’s gravity quickly during his first day back, which was mainly spent flying from Kazakhstan back to Houston.

The new in-the-field experiments will be the first of a dataset on astronaut health, meant to provide more information ahead of the first one-year trip to the International Space Station.
