When there’s a Dragon spacecraft coming your way at the International Space Station, you’d better be ready to grapple it with a robotic arm. For if there’s a crash, you will face “a very bad day”, as astronaut David Saint-Jacques points out in this new video (also embedded below the jump).
That’s why the Canadian (along with European Space Agency astronaut Andreas Mogensen) was doing robotics training this month at the Canadian Space Agency headquarters near Montreal. The most terrifying thing for astronauts must be the limited view as they do delicate maneuvers with the multi-million dollar Canadarm2.
“All you’ve got, really, while you’re working, is this workstation,” Saint-Jacques said. “You’ve got a couple of camera views to work from. You’ve got your hand controllers to move the arm, and you’ve got some computer displays, and a bunch of switches here on the left.”
“That’s all you’ve got,” he added. “You’ve really got to think ahead: how you’re going to maneuver this arm without crashing into anything.”
The video is the latest in a training series by Mogensen, who will go to the International Space Station in 2015. Saint-Jacques — a fellow 2009 astronaut class selectee — has not been assigned to a flight yet (at least publicly).
The first Canadarm, which cost about $100 million in late 1970s dollars, flew on the second shuttle flight in 1981. Canadarm2 was constructed for space station construction in the 2000s, and is still used today for spacewalks.
Berthing spacecraft is reportedly not what it was originally designed for, but the robotic arm has proved an able tool to pick up the Dragon spacecraft and other visitors to the station.
“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.
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.
If you’ve ever felt insecure about your height, orbit is a great place to be. Astronaut spines lengthen up to 2.75 inches (7 centimeters) while they’re in microgravity. There are big downsides, however. First there’s the backache. Second, you’re four times as likely to get a slipped disc when you return to Earth.
The solution could be as simple as tight clothing. Above you can see French astronaut Thomas Pesquet (already flying high this week after he was publicly named to a flight in 2016) trying out a prototype of the skinsuit. Essentially, it’s so tight that it could prevent you from growing, which in turn would stop the pain and risk of damage.
“The skinsuit is a tailor-made overall with a bi-directional weave specially designed to counteract the lack of gravity by squeezing the body from the shoulders to the feet with a similar force to that felt on Earth. Current prototypes are made of spandex, although new materials are being examined,” the European Space Agency wrote.
The first astronaut to test the suit out in space will be Andreas Mogensen, who will launch to the International Space Station next year.
ESA says if it works, the suit would not only be useful for astronauts, but also could be great for people with back pain on Earth — and possibly, even those with conditions such as cerebral palsy.
Prototypes are being developed between ESA’s Space Medicine Office, King’s College London (United Kingdom), University College London (United Kingdom) and the Massachusetts Institute of Technology (United States).
Three red roses and a white one. The flower bouquet sitting in NASA Mission Control right now in Houston is one of a series that has appeared with every single mission since 1988 — a small gift from a Texas family whose members are long-standing fans of space exploration.
The first bouquet showed up on landing day for the first flight (STS-26) after the shuttle Challenger explosion. And bouquets have continued for every flight since, a gift that NASA is glad to see when it arrives.
“It means a lot to the team here in Houston,” NASA spokesperson Josh Byerly said in the YouTube video above, an excerpt from a broadcast on NASA TV. “We’re big on tradition here at NASA, and we are very happy that this tradition continues.”
Each red rose symbolizes a member of an expedition crew — in this case, Expedition 39/40‘s Steve Swanson (NASA), Alexander Skvortsov (Roscosmos) and Oleg Artemyev (Roscosmos). The white one is a symbol of all of the astronauts who have lost their lives, such as those in the Apollo 1, Challenger and Columbia disasters.
“When I first walked into the control room I noticed them right away, because it was so different, and I walked over and read the card,” stated Milt Heflin, who was a shuttle flight director at the time. “It was very simple, saying congratulations and wishing everyone the best on the mission. It was signed but it didn’t have any contact information for the senders.”
Helfin did manage to track down the family — Mark, Terry and daughter MacKenzie — and over the years, the Sheltons received cards of thanks and invitations to see launches and Mission Control.
“I didn’t actually decide to do it until the day the STS-26 mission was to land, and I didn’t know that I even could get it done in time,” Mark Shelton stated, who added he first became interested in space after a childhood visit to the NASA Johnson Space Center in Houston in the 1960s.
“I called information to find a florist near the space center, and then I asked the florist if they could deliver roses to Mission Control. At first they said they couldn’t do it … but then they said they would try.”
The attempt succeeded, obviously, and with each mission new flowers arrive. The bouquets are now including participation from a “second” generation, Byerly said in the video, saying that they now come from the Sheltons and the Murphys.
Imagine that you were in the middle of a module on the International Space Station. Floating in mid-air, far from handholds or any way to propel yourself. Is there any way to get out of that situation?
The short answer is not easily, and the longer answer is it could be an effective way to trap criminals in space, joked veteran cosmonaut Maxim Suraev in a press conference today (March 18) for the upcoming Expedition 40/41 mission, which also includes rookies Alex Gerst and Reid Wiseman.
Speaking in Russian, Suraev explained that during his last 2010 mission, he had crew members set him up in the middle of the station’s Node 3. “It is true that you can twist as much as a contortionist, but you won’t be able to move because you have nothing to bear against,” he said in remarks translated into English.
That said, the ventilation system on station does tend to push objects (and people) towards the vents after a time, he observed. What if you had multiple vents set up, however?
“I thought that if ever we have a permanent human habitation in space, this would be the best way to keep a person confined — like in a prison — in the middle of the room, where he or she could not move anywhere,” Suraev continued. “Being in limbo, as you will. The only thing that is required is a large room, a person and several fans blowing in different directions to keep the person in the middle of the room. That’s scary, trust me!”
There’s no fear on Suraev’s part that it will happen with his crewmates, however. “My new crew, they’re really good guys and I’m really looking forward to being with my new crew in space, and to spend five and a half months aboard the space station,” he said in an English phone interview after the press conference. (Good news given that Suraev will assume command of Expedition 41.)
The crew (who lifts off in May) will have an action-packed mission. It will include the arrival of the last Automated Transfer Vehicle (ATV) and — if NASA fixes on a spacesuit leak allow — two American maintenance spacewalks. There also are 162 experiments to perform (this according to Gerst) and if there’s time, checking out our home planet.
“Earth observation was not one of the primary goals that [station] was designed for,” he cautioned in a phone interview, but he added that one of its strengths is there are people on board the orbiting laboratory that can fill in the gaps for other missions.
Gerst (who was a volcano researcher before becoming an astronaut) pointed out that if a volcano erupts, a typical Earth satellite would look straight down at it. Astronauts can swing around in the Cupola and get different views quickly, which could allow scientists to measure things such as the volcano plume height.
Another example of flexibility: The Expedition 39 crew right now is (news reports say) helping out with the search for the missing Malaysian Airline Flight 370.
“We’re really good at capturing things quickly and then sending the pictures down to the ground,” Gerst said.
Wiseman, as one of the rookies on mission, says he is interested in comparing the experience to his multi-month Navy missions at sea. It’s all a matter of mindset, he said in a phone interview. He once was assigned to a naval voyage that was expected to be at sea for six months. Then they were instructed it would be 10 months, leading to fistfights and other problems on board, he recalled.
Astronauts for the forthcoming one-year mission to station, he pointed out, will launch with different expectations than someone expecting about a six-month stay. “If you know you’re up there for one year, you’re going to pace yourself for one year,” he said.
But there still will be sacrifices, as Wiseman has two daughters (five years old and eight years old). He’s asking the older child to do a bit of social media, and the younger one to draw pictures that could be included in the “care packages” astronauts receive from Earth. “It’s going to be tough not to see them on a daily basis. They grow so fast,” he said.
Other things to watch for on this mission include the arrival of the station’s first 3-D printer, setup of an alloy furnace to make new materials in microgravity, and a potential Wiseman-led “come out and wave campaign” that would encourage families to go outside and tweet about the space station as they watch it.

Legs — yes, legs — are on the manifest for the next SpaceX Dragon flight. The commercial spacecraft is expected to blast off March 16 with appendenges for Robonaut 2 on board, allowing the humanoid to move freely around station. After some initial tests in June will come R2’s first step, marking a new era in human spaceflight.
What’s exciting about R2 is not only its ability to take over simple tasks for the astronauts in station, but in the long run, to head “outside” to do spacewalks. This would greatly reduce risk to the astronauts, as extravehicular activity is one of the most dangerous things you can do outside (as a spacesuit leak recently reminded us.)
When installed, Robonaut will have a “fully extended leg span” of nine feet (wouldn’t we love to see the splits with that). Instead of a foot, each seven-jointed leg will have an “end effector” that is a sort of clamp that can grab on to things for a grip. It’s similar to the technology used on the Canadarm robotic arm, and also like Canadarm, there will be a vision system so that controllers know where to grasp.
The robot first arrived on station in February 2011 and (mostly while tied down) has done a roster of activities, such as shake hands with astronaut Dan Burbank in 2012 (a humanoid-human first in space), say hello to the world with sign language, and do functions such as turn knobs and flip switches. During Expedition 34/35 in 2012-13, astronaut Tom Marshburn even made Robonaut 2 catch a free-floating object through teleoperation.
Eventually NASA expects to use the robot outside the station, but more upgrades to Robonaut 2’s upper body will be needed first. The robot could then be used as a supplement to spacewalks, which are one of the most dangerous activities that humans do in space.
Closer to Earth, NASA says the technology has applications for items such as exoskeletons being developed to help people with physical disabilities.
If your spaceship comes back in rural Kazakhstan, and it’s blowing snow, and rescue forces can’t get there right away, how would you survive the cold? This winter survival video below shows how cosmonauts and astronauts would leave the spacecraft and make shelter while waiting for help to arrive.
An even more complicated scenario would arise if the crew member was injured, explain European Space Agency astronauts Andreas Mogensen and Thomas Pesquet, who were reflecting on Mogensen’s survival training in January in the video.
The video shows crew members creating a makeshift brace for a broken arm, which would be painful — but would not necessarily inhibit walking. If it was a broken leg, other crew members would need to carry the injured person — slowing down the march if they needed to move to another location.
SpaceX is nearly ready to Rock ‘n’ Roll with their first rocket sporting landing legs and slated to blast off this coming weekend carrying a commercial Dragon cargo freighter bound for the International Space Station (ISS).
Check out the Falcon 9 rockets gorgeous legs unveiled today by SpaceX in an eye popping new photo featured above.
The newly released image shows the private Falcon 9 positioned horizontally inside the Cape Canaveral processing hanger and looking up directly from the bottom of her legs and nine powerful first stage engines.
Following a brief static hotfire test this past weekend of all nine upgraded Merlin 1D engines powering the first stage of SpaceX’s next generation Falcon 9 rocket, the path is clear for Sunday’s (March 16) night time lift off at 4:41 a.m. EDT from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida.
This week, engineers working inside the hanger are loading the Dragon vessel with the final cargo items bound for the station that are time sensitive.
Altogether, this unmanned SpaceX CRS-3 mission will deliver over 5000 pounds of science experiments and essential gear, spare parts, crew provisions, food, clothing and supplies to the six person crews living and working aboard the ISS soaring in low Earth orbit under NASA’s Commercial Resupply Services (CRS) contract.
Dragon is carrying research cargo and equipment for over 150 science investigations, including 100 protein crystal experiments that will allow scientists to observe the growth of crystals in zero-G.
Conducted in the absence of gravity, these space experiments will help Earth bound researchers to potentially learn how to grow crystals of much larger sizes compared to here on Earth and afford scientists new insights into designing and developing new drugs and pesticides.
A batch of new student science experiments are also packed aboard and others will be returned at the end of the mission.
The attachment of landing legs to the first stage of SpaceX’s next-generation Falcon 9 rocket counts as a major first step towards the firm’s future goal of building a fully reusable rocket.
For this Falcon 9 flight, the rocket will sprout legs for a controlled soft landing in the Atlantic Ocean guided by SpaceX engineers.
“F9 will continue to land in the ocean until we prove precision control from hypersonic thru subsonic regimes,” says SpaceX CEO and founder Elon Musk.
It will be left to a future mission to accomplish a successful first stage touchdown by the landing legs on solid ground back at Cape Canaveral, Florida.
Much development works remains before a land landing will be attempted.
The Falcon will roll out from the hanger to Launch Pad 40 on Saturday, March 15.
SpaceX is under contract to NASA to deliver 20,000 kg (44,000 pounds) of cargo to the ISS during a dozen Dragon cargo spacecraft flights over the next few years at a cost of about $1.6 Billion.
To date SpaceX has completed two operational cargo resupply missions and a test flight to the station. The last flight dubbed CRS-2 blasted off a year ago on March 1, 2013 atop the initial version of the Falcon 9 rocket.
Following the scheduled March 16 launch and a series of orbit raising and course corrections over the next two days, Dragon will rendezvous and dock at the Earth facing port on the station’s Harmony module on March 18.
The Harmony port was recently vacated by the Orbital Sciences built Cygnus cargo spacecraft to make way for Dragon.
This extra powerful new version of the Falcon 9 dubbed v1.1 is powered by a cluster of nine of SpaceX’s new Merlin 1D engines that are about 50% more powerful compared to the standard Merlin 1C engines. The nine Merlin 1D engines 1.3 million pounds of thrust at sea level rises to 1.5 million pounds as the rocket climbs to orbit.
Therefore the upgraded Falcon 9 can boost a much heavier cargo load to the ISS, low Earth orbit, geostationary orbit and beyond.
Indeed Dragon is loaded with about double the cargo weight carried previously.
The Merlin 1D engines are arrayed in an octaweb layout for improved efficiency.

NASA’s preliminary (read: not finalized) budget for 2015 would eliminate funding for the long-running Opportunity rover mission that’s discovered extensive evidence of past water on Mars in the past decade.
While the agency’s baseline budget request shows no funding for the long-running Mars mission past 2015, NASA added that Opportunity is among several missions that could receive extension money if extra funds become available. Also, the budget needs to be approved by Congress before anything is set in stone.
Here’s where Opportunity could get funding, under the current structure: The White House has proposed a $56 billion “Opportunity, Growth and Security Initiative” across the U.S. government that would surpass the budgetary spending limit that Congress set in December. (Some news reports indicate the Republicans are not on board with this, but it’s early yet.)
Within NASA, that translates into an extra $885.5 million that would be used for certain priority areas in science, aeronautics, space technology, exploration, space operations, education and other items. If the funding goes through and if it is approved in full, Opportunity could receive money within $35 million allocated in planetary science extended mission funding for 2015.
NASA, meanwhile, is undertaking a regular review of several Mars programs (among others) to see which ones give the best return for funding. “The missions to be reviewed include MSL [Mars Science Laboratory/Curiosity], MRO [Mars Reconnaissance Orbiter], Opportunity, Odyssey and Mars Express,” NASA stated. But as the table below shows, right now Opportunity has no funding in fiscal 2015, while the other missions do. (Note that funding would cease for Odyssey in 2017 under this plan.)
Here’s what NASA’s budget request says about the extended funding:
“Planetary Science Extended Mission Funding: Provide an additional $35.0 million to increase support for extended missions prioritized in the upcoming 2014 Senior Review. The Budget provides funding for high priority extended missions such as Cassini and Curiosity. However, it does not provide funding to continue all missions that are likely to be highly rated in Senior Review. The funding augmentation would allow robust funding for all extended missions that are highly ranked by the 2014 Senior Review, enabling high science return at relatively low cost, instead of potentially terminating up to two missions or reducing science across many or all of them.”
On Twitter, the Planetary Society’s Casey Dreier, its director of advocacy, wrote a few tweets about the budget last night, including one addressing Opportunity. “As expected, MER Opportunity has no funding as of Oct 1st, unless supplemental funding is added,” he said, adding that a bright spot is that the Curiosity mission has funding through fiscal 2019 (which is as far as the numbers go in the budget request.)
Opportunity landed on Mars in January 2004 and has rolled more than 24 miles (38 kilometers) in the years since, long outliving its twin Spirit (who ceased communications in 2010). Universe Today’s Ken Kremer recently covered the contributions these rovers made to science in the past 10 years.
On an unrelated note, NASA announced today (March 11) that the Mars Reconnaissance Orbiter went into safe mode “after an unscheduled swap from one main computer to another”, but the spacecraft is expected to be working normally in a few days. (MRO has been through several safe mode incidents over the years, including several times in 2009.)
It’s not often that one associates a satellite with French folk songs, but this infographic does that and more. Below you will find the major launches of the early space age — from the Soviet Union’s Sputnik to the Czechoslovakian Magion 1 — showing how satellites quickly evolved between 1957 and 1978.
In two decades, satellites changed from simple transmitters and receivers to sophisticated machines that carried television signals and science instruments.
Another striking thing about this Broadband Wherever graphic: the number of participating countries. While we often think of the early Space Age as being dominated by the United States and Soviet Union, you can see other nations quickly rushing their own satellites into orbit: Canada, Italy, Australia, India and more.
