The change of command ceremony on the ISS. Via NASA TV.
With the Canadian national anthem playing, astronaut Chris Hadfield accepted the “keys” to the International Space Station from outgoing Expedition 34 commander Kevin Ford, as Hadfield became the first Canadian commander of the space station.
“Thank you very much for giving me the keys to the family car… we’re going to put some miles on it,” Hadfield said during the change of command ceremonies held on the ISS today, marking the start of the Hadfield-led Expedition 35.
“It is a tremendous honour to assume command of the ISS,” Hadfield said in a statement issued by the Canadian Space Agency. “I will do my best to acquit myself well, accomplish the utmost as a crew for all the International Partners, and fully live and share the experience on behalf of so many around our world”.
“It’s a first for our country,” Hadfield continued, “but is really just the culmination of a lot of other firsts. I stand on the shoulders of so many that have made this possible, and now take my turn to try and add to that solid foundation for the Canadians that follow.”
Ford and Russian cosmonauts Oleg Novitskiy and Evgeny Tarelkin arrived at the station on October 25, 2012 and leave the ISS on Friday, March 15, 2013, making a landing on the steppe of Kazakhstan in their Soyuz TMA-06M spacecraft. Remaining on board with Hadfield are NASA astronaut Tom Marshburn and Russian Flight Engineer Roman Romanenko. They will be joined on March 29 by Expedition 35/36 crew members Pavel Vinogradov, NASA Flight Engineer Chris Cassidy and Flight Engineer Alexander Misurkin.

Don Pettit has always been one of our favorite astronauts. From his “Saturday Morning Science” and “Science Off the Sphere” to his Zero-G coffee cup, he offered a take on living and working in space that was always just a bit different from the rest of the astronaut corps. During his last stay on the International Space Station, he took photography to a new level, and fellow astrophotographer Christoph Malin has paid a fitting tribute to Pettit with this wonderful new video, which not only showcases Pettit’s work (and Malin’s too!), but allows him to explain the challenges of astrophotography aboard the ISS.
“It can not be emphasized enough, how Dr. Pettits innovative photographic work and his passion has changed the way we see earth from space,” Malin wrote on his Vimeo page. You can read about the genesis of this project at Malin’s website.

Imagine visiting Star Fleet headquarters in the 23nd Century and being engulfed by a holodeck journey to a 21st century NASA Space Shuttle; complete with a full sized Hubble Space Telescope – perhaps the important science instrument ever constructed and an outstanding legacy of the Space Shuttle Program.
Well that’s the thrilling new experience awaiting the visiting public and space enthusiasts alike starting this summer at the Kennedy Space Center Visitor Complex (KSCVC) in Florida – after the ghostlike Space Shuttle Atlantis (see photo album above & below) is unveiled from a thick coating of shrink wrapped plastic.
But – there is one important caveat regarding the holodeck dream sequence.
Starting on June 29 you will be seeing the ‘real deal’, an actual space flown NASA Space Shuttle Orbiter – not a high tech imaginary glimpse, engineering reproduction or holodeck recreation.
During the recent SpaceXCRS-2 launch events, I was very fortunate to take a behind the scenes inspection tour all around of the new ‘Space Shuttle Atlantis’ pavilion that’s been under construction at the Kennedy Visitor Complex for a year and is now racing towards completion.
And Atlantis is still supremely impressive beneath that white plastic wrap – unlike any shuttle view I’ve see over the years.
Scan through my photo album walking around Atlantis – covered in 16,000 square feet of shrink wrap plastic – and the Star Fleet like pavilion that truly reminded me of an exciting Star Trek adventure ; to see what’s in store soon. The orange exterior pavilion facade is meant to evoke the scorching heat of reentry into the Earth’s atmosphere.

The plastic wrap is protecting the orbiter from construction debris and will be unfurled in May. Then the payload bay doors will be carefully opened and the Canadian built remote manipulator system (RMS) — or robotic arm — will be installed and extended.
Inside her new 90,000-square-foot home, everyone will be treated to breathtaking, up close views of the real ‘Space Shuttle Atlantis’ mounted high on steel pedestals – tilted at exactly 43.21 degrees – simulating the outlook as though she was ‘in flight’ orbiting Earth and approaching the International Space Station (ISS).
The ISS and Hubble are the primary legacies of the Space Shuttle program. Atlantis flew 33 total space missions, spent 307 days in orbit and conducted the final flight of the shuttle era.

You’ll gaze from stem to stern and from above and below – and all while peering down into the humongous open cargo bay, up to the heat shield tiles, or across to the engines, wings, tail and crew flight deck. Walkways will provide exquisite up close viewing access.
Atlantis rises some 30 feet off the ground. Although her nose soars 26.5 feet above ground the portside wingtip sits only 7.5 feet from the floor. The wing tip top soars 87 feet from the ground.
And sitting right beside Atlantis will be a co-orbiting, high fidelity full scale replica of NASA’s Hubble Space Telescope which was deployed and upgraded by the astronaut crews of six space shuttle missions.
ISS module mockups, simulators and displays will tell the story of the massive stations intricate assembly by several dozen shuttle crews.

More than 60 exhibits, hands- on activities and artifacts surrounding Atlantis will tell the complete story of the three-decade long Space Shuttle program and the thousands of shuttle workers who prepared all five orbiters for a total of 135 space missions spanning from 1981 to 2011.
Atlantis has been lovingly preserved exactly as she returned upon touchdown at the shuttle landing strip at the conclusion of her last space mission, STS-135, in July 2011 – dings, dents, scorch marks, you name it. And that is exactly as it should be in my opinion too.

Shuttle Atlantis was towed to the Visitor Complex in November. The orbiter is housed inside a spanking new six- story museum facility constructed at a cost of $100 million that dominates the skyline at the largely revamped Kennedy Space Center Visitor Complex.

Standing tall right outside the entry to the museum pavilion, visitors will see full scale replicas of the twin solid rocket boosters mated to the orange external fuel tank, suspended 24 feet above ground – and reaching to a top height of 185 feet. They will be erected vertically, precisely as they were at the Shuttle Launch Pads 39 A and 39 B. It will give a realistic sense of what it looked like atop the actual shuttle launch complex.
The mighty steel framework for holding the boosters in place (in case of hurricane force winds up to 140 MPH) was coming together piece by piece as workers maneuvered heavy duty cranes before my eyes during my pavilion museum tour just days ago.
Well, get set to zoom to space as never before beginning on June 29 with the last shuttle orbiter that ever flew in space.

The first light from the new ISERV camera system, taken on February 16, 2013 shows the Rio San Pablo as it empties into the Golfo de Montijo in Veraguas, Panama. NASA image by Burgess Howell, SERVIR Global program.
As we reported in January, a new telescope was installed on the International Space Station – not to observe the stars, but instead look back to Earth to acquire imagery of specific areas of the world for disaster analysis and environmental studies. Called ISERV (International Space Station SERVIR Environmental Research and Visualization System), it has now taken its first image. Above is the “first light” from the new ISERV, taken at 1:44 p.m. local time on February 16, 2013.
No, this is not a giant tree trunk! It is the Rio San Pablo as it empties into the Golfo de Montijo in Veraguas, Panama.
The telescope is a modified off-the-shelf Celestron telescope, the Celestron CPC 925, a 9.25? diffraction limited Schmidt-Cassegrain telescope and if you were to buy a un-modified version, it would cost $2,500 including the mount.
The ISERV version was modified at the Marshall Space Flight Center, which is where it is controlled from, as well. It is installed in the Window Observational Research Facility (WORF) in the station’s Destiny laboratory. With a resolution down to 3.2 meters (10 feet), it will be possible to spot fairly small details and objects.

This ISERV Pathfinder is intended as an engineering exercise, with the long-term goal of developing a system for providing imagery to developing nations as they monitor natural disasters and environmental concerns.
“ISERV’s full potential is yet to be seen, but we hope it will really make a difference in people’s lives,” said principal investigator Burgess Howell of NASA’s Marshall Space Flight Center. “For example, if an earthen dam gives way in Bhutan, we want to be able to show officials where the bridge is out or where a road is washed out or a power substation is inundated. This kind of information is critical to focus and speed rescue efforts.”
The system will use on positioning software to know where the space station is at each moment and to calculate the next chance to view a particular area on the ground. If there’s a good viewing opportunity, the SERVIR team will instruct the camera to take high-resolution photographs at 3 to 7 frames per second, totaling as many as 100 images per pass.
The current mission will test the limitations of this ISERV system and identify measures for improvements in a more permanent system. For instance, the engineering team is working to determine how the geometry of the ISS window affects the imagery; how much sunlight is needed to capture clear images; and how the atmosphere affects that clarity. This characterization phase will last several weeks to a few months. Eventually, ISERV should be made available to the natural hazards community and to basic research scientists.

Sunday was a big day in space, and astronaut Chris Hadfield captured the excitement in photos, and shared them via Twitter. “What a day!” Hadfield tweeted. “Reached & grabbed a Dragon, berthed her to Station & opened the hatch to find fresh fruit, notes from friends, and peanut butter.”
SpaceX’s Dragon spacecraft overcame a problem with its thrusters after reaching orbit on Friday, and on Sunday Dragon successfully approached the Station, where it was captured by Expedition 34 Commander Kevin Ford and crewmate Tom Marshburn using the station’s Canadarm2 robotic arm. Dragon was grappled at 5:31 a.m. EST, and was berthed to the Earth-facing port of the Harmony module at approximately 8:56 a.m. EST on March 3.
See more photos below. The image captions are Hadfield’s Tweets.

Kennedy Space Center – After overcoming a frightening thruster failure that could have spelled rapid doom on the heels of a breathtakingly beautiful launch, the privately developed Dragon spacecraft successfully berthed at the International Space Station (ISS) a short while ago, at 8:56 a.m. EST Sunday morning, March 3, 2013 – thereby establishing an indispensable American Lifeline to the massive orbiting lab complex.
Hearts sank and hopes rose in the span of a few troubling hours following Friday’s (Mar. 1) flawless launch of the Dragon cargo resupply capsule atop the 15 story tall Falcon 9 rocket from Cape Canaveral Air Force Station, Florida and the initial failure of the life giving solar arrays to deploy and failure of the maneuvering thrusters to fire.
“Congrats to the @NASA/@SpaceX team. Great work getting #Dragon to the #ISS…our foothold for future exploration!” tweeted NASA Deputy Administrator Lori Garver.
Space station Expedition 34 crew members Kevin Ford and Tom Marshburn of NASA used the station’s 58 foot long Canadian supplied robotic arm to successfully grapple and capture Dragon at 5:31 a.m. Sunday as the station was flying 253 miles above northern Ukraine. See the grappling video – here.

“The vehicle’s beautiful, space is beautiful, and the Canadarm2 is beautiful too”, said station commander Kevin Ford during the operation.
The capsule pluck from free space came one day, 19 hours and 22 minutes after the mission’s launch.
Ground controllers at NASA’s Johnson Space Center in Houston then commanded the arm to install Dragon onto the Earth-facing port of the Harmony module – see schematic.

Originally, Dragon capture was slated only about 20 hours after launch. But that all went out the window following the serious post-launch anomalies that sent SpaceX engineers desperately scrambling to save the flight from a catastrophic finale.
The $133 million mission dubbed CRS-2 is only the 2nd contracted commercial resupply mission ever to berth at the ISS under NASA’s Commercial Resupply Services (CRS) contract. The contract is worth $1.6 Billion for at least a dozen resupply flights.
Following the forced retirement of NASA’s space shuttle orbiters in July 2011, American was left with zero capability to launch either cargo or astronauts to the primarily American ISS. NASA astronauts are 100% reliant on Russian Soyuz capsules for launch to the ISS.
Both the Falcon 9 rocket and Dragon spacecraft were designed and built by SpaceX Corporation based in Hawthorne, Calif., and are entirely American built.
The Falcon 9/Dragon commercial system restores America’s unmanned cargo resupply capability. But the time gap will be at least 3 to 5 years before American’s can again launch to the ISS aboard American rockets from American soil.
And continuing, relentless cuts to NASA’s budget are significantly increasing that human spaceflight gap and consequently forces more payments to Russia.
“Today we marked another milestone in our aggressive efforts to make sure American companies are launching resupply missions from U.S. shores,” said NASA Admisistrator Charles Bolden in a NASA statement.
“Our NASA-SpaceX team completed another successful berthing of the SpaceX Dragon cargo module to the International Space Station (ISS) following its near flawless launch on the Falcon-9 booster out of Cape Canaveral, Florida Friday morning. Launching rockets is difficult, and while the team faced some technical challenges after Dragon separation from the launch vehicle, they called upon their thorough knowledge of their systems to successfully troubleshoot and fully recover all vehicle capabilities. Dragon is now once again safely berthed to the station.”
“I was pleased to watch the launch from SpaceX’s facility in Hawthorne, CA, and I want to congratulate the SpaceX and NASA teams, who are working side by side to ensure America continues to lead the world in space.”
“Unfortunately, all of this progress could be jeopardized with the sequestration ordered by law to be signed by the President Friday evening. The sequester could further delay the restarting of human space launches from U.S. soil, push back our next generation space vehicles, hold up development of new space technologies, and jeopardize our space-based, Earth observing capabilities,” said Bolden.

Dragon is loaded with about 1,268 pounds (575 kilograms) of vital supplies and provisions to support the ongoing science research by the resident six man crew, including more than a ton of vital supplies, science gear, research experiments, spare parts, food, water and clothing.
NASA says that despite the one-day docking delay, the Dragon unberthing will still be the same day as originally planned on March 25 – followed by a parachute assisted splashdown in the Pacific Ocean off the coast of Baja California.
Dragon will spend 22 days docked to the ISS. The station crew will soon open the hatch and unload all the up mass cargo and research supplies. Then they will pack the Dragon with about 2,668 pounds (1,210 kilograms) of science samples from human research, biology and biotechnology studies, physical science investigations, and education activities for return to Earth.

Dragon is the only spacecraft in the world today capable of returning significant amounts of cargo to Earth.
Orbital Sciences Corp also won a $1.9 Billion cargo resupply contract from NASA to deliver cargo to the ISS using the firm’s new Antares rocket and Cygnus capsule.
NASA hopes the first Antares/Cygnus demonstration test flight from NASA’s Wallops Island Facility in Virginia will follow in April. Cygnus cargo transport is one way – to orbit only.
“SpaceX is proud to execute this important work for NASA, and we’re thrilled to bring this capability back to the United States,” said Gwynne Shotwell, President of SpaceX.
“Today’s launch continues SpaceX’s long-term partnership with NASA to provide reliable, safe transport of cargo to and from the station, enabling beneficial research and advancements in technology and research.”
The SpaceX CRS-3 flight is slated to blast off in September 2013.

Kennedy Space Center – All systems are GO and the weather outlook looks spectacular for the March 1 blast off of the privately developed SpaceX Falcon 9 rocket to the International Space Station (ISS).
The Falcon 9 is slated to lift off at 10:10 AM EST with a Dragon capsule loaded with fresh supplies and science gear to continued full up operation and utilization of the ISS.
Right now the weather forecast is at 80% GO on March 1 – with superbly beautiful, clear blue skies here in sunny and comfortably warm Florida from Space Launch Complex 40 at Cape Canaveral Air Force Station.
Large crowds of eager tourists, sightseers and space enthusiasts are already gathering in local hotels – most are sold out including at my hotel where I have been holding well attended ISS star parties during excellent evening viewing opportunities this week.
NASA TV will provide live launch coverage starting at 8 30 AM. SpaceX will also provide a separate feed starting about 40 minutes prior to launch.
The two stage Falcon 9 rocket was rolled out horizontally to the pad late this afternoon (Thursday, Feb. 28) in anticipation of a Friday morning launch. Myself and Dave Dickinson are on-site for Universe Today
The mission dubbed CRS-2 will be only the 2nd commercial resupply mission ever to the ISS.
There are no technical concerns at this time. Saturday March 2 is the back-up launch date in case of a last second scrub. Weather is projected as 80% favorable.
SpaceX President Gwynne Shotwell and NASA officials told me that additional launch opportunities are available Sunday, Monday and Tuesday, if needed, and later until about March 11. After that, the launch team would have to stand down to make way for the next eventual departure of a docked Soyuz and launch of a manned Russian Soyuz capsule with a new three man crew.

The SpaceX Dragon capsule is carrying about 1,200 pounds of vital supplies and research experiments for the six man international crew living aboard the million pound orbiting outpost.
SpaceX is under contract to NASA to deliver over 44,000 pounds of cargo to the ISS during a dozen flights over the next few years at a cost of about $1.6 Billion.
The capsule is fully loaded Shotwell told me. An upgraded Falcon 9 will be used in the next launch that will allow for a significant increase in the cargo up mass, Shotwell elaborated.
The Dragon is due to dock with the ISS in record time some 20 hours after blast off.
'The full moon rises over the only planet we have ever called home,' Tweeted astronaut Chris Hadfield.
We never get tired of these amazing views from the International Space Station, but this one has it all: a silvery Moon setting into the Earth’s atmosphere, the dazzling Milky Way rising into a brilliant sunrise, airglow of all colors, popping lightning, shimmering aurorae, and incredible views of the stunning space station and our gorgeous planet. Brian Tomlinson put this one together, using stills from the Johnson Space Center’s “Gateway to Astronaut Photography of the Earth.”

Well, having survived high speed wayward Asteroids and Meteors these past few days, the human crew circling Earth aboard the International Space Station (ISS) is game to snatch a flying Space Dragon before too long.
NASA will dispatch astronaut fun to orbit in the form of the privately built SpaceX Dragon in a tad less than two weeks time that the crew will ensnare with that robotic hand from Canada and join to the ISS.
On March 1 at 10:10 AM EST, a Space Exploration Technologies (SpaceX) Falcon 9 rocket is slated to blast off topped by the Dragon cargo vehicle on what will be only the 2nd commercial resupply mission ever to the ISS.
The flight, dubbed CRS-2, will lift off from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida carrying about 1,200 pounds of vital supplies and science experiments for the six man international crew living aboard the million pound orbiting outpost.

The ISS would plummet from the sky like a flaming, exploding meteor and disintegrate without periodic and critical cargo and fueling resupply flights from the ISS partner nations.
There will be some heightened anticipation for the March 1 SpaceX launch following the premature shutdown of a 1st stage Merlin engine during the last Falcon 9 launch in 2012.
The solar powered Dragon capsule will rendezvous with the ISS a day later on March 2, when NASA astronauts Kevin Ford and Tom Marshburn will reach out with the Canadian built robotic marvel, grab the Dragon by the proverbial “tail” and attach it to the Earth-facing port of the station’s Harmony module.
The Dragon will remain docked to the ISS for about three weeks while the crew unloads all manner of supplies including food, water, clothing, spare parts and gear and new science experiments.
Then the astronauts will replace all that cargo load with numerous critical experiment samples they have stored during ongoing research activities, as well as no longer needed equipment and trash totaling about 2300 pounds, for the return trip to Earth and a Pacific Ocean splashdown set for March 25 – as things stand now.

SpaceX is under contract to NASA to deliver about 44,000 pounds of cargo to the ISS during a dozen flights over the next few years at a cost of about $1.6 Billion.
SpaceX comprises one half of NASA’s Commercial Resupply Services program to replace the cargo up mass capability the US lost following the retirement of NASA’s space shuttle orbiters in 2011.
SpaceX also won a NASA contract to develop a manned version of the Dragon capsule and aims for the first crewed test flight in about 2 to 3 years – sometime during 2015 depending on the funding available from NASA.
The US is now totally dependent on the Russians to loft American astronauts to the ISS on their Soyuz capsules for at least the next 3 to 5 years directly as a result of the shuttle shutdown.
Along with SpaceX, Orbital Sciences Corp also won a $1.9 Billion cargo resupply contract from NASA to deliver some 44,000 pounds of cargo to the ISS using the firm’s new Antares rocket and Cygnus capsule – launching 8 times from a newly constructed pad at NASA’s Wallops Island Facility in Virginia.
The maiden launch of Orbital’s Antares/Cygnus system has repeatedly been delayed – like SpaceX before them.
NASA hopes the first Antares/Cygnus demonstration test flight will now occur in March or April. However, the Antares 1st stage hot fire test scheduled for earlier this week on Feb. 13 had to be aborted at the last second due to a technical glitch caused by a low nitrogen purge pressurization.
For the SpaceX launch, NASA has invited 50 lucky social media users to apply for credentials for the March 1 launch

Our home planet is due for a record setting space encounter on Friday (Feb. 15) of this week, when a space rock roughly half a football field wide skirts very close by Earth at break neck speed and well inside the plethora of hugely expensive communications and weather satellites that ring around us in geosynchronous orbit.
“There is no possibility of an Earth impact” by the Near Earth Asteroid (NEO) known as 2012 DA 14, said Don Yeomans, NASA’s foremost asteroid expert at a media briefing. Well that’s good news for us – but a little late for the dinosaurs.
At its closest approach in less than 4 days, the 45 meter (150 feet) wide Asteroid 2012 DA14 will zoom by within an altitude of 27,700 kilometers (17,200 miles). That is some 8000 km (5000 miles) inside the ring of geosynchronous satellites, but far above most Earth orbiting satellites, including the 6 person crew currently working aboard the International Space Station.
Although the likelihood of a satellite collision is extremely remote, NASA is actively working with satellite providers to inform them of the space rocks path.
The razor thin close shave takes place at about 2:24 p.m. EST (11:24 a.m. PST and 1924 UTC) as the asteroid passes swiftly by at a speed of about 7.8 kilometers per second (17,400 MPH)- or about 8 times the speed of a rifle bullet. For some perspective, it will be only about 1/13th of the distance to the moon at its closest.
“Asteroid 2012 DA14 will make a very close Earth approach, traveling rapidly from South to North and be moving at about two full moons per minute,” said Yeomans, who manages NASA’s Near-Earth Object Program Office at the Jet Propulsion Laboratory in Pasadena, Calif. “That’s very fast for a celestial object.”

No known asteroid has ever passed so near to Earth.
“This is a record predicted close approach for a known object this size,” stated Yeomans. “Such close flybys happen every 40 years on average. An actual Earth collision would happen about every 1200 years.”
Yeomans said that if an asteroid the size of 2012 DA14 fell to Earth, the impact effect would be similar to the 1908 Tunguska event in Siberia. That was an air blast event that leveled trees over an area greater than about 800 square miles.
So the local effect on human cities for example of a 50 meter wide asteroid impact would be deadly and utterly devastating. But it would not be catastrophic to all life on Earth. Nevertheless, at this moment, Earth has no defenses against asteroids other than talk.
By comparison, the K-T event that caused the mass extinction of the dinosaurs some 65 million years ago was caused by an asteroid about 10 km (6 mi) in diameter. About 2/3 of all species went extinct. If 2012 DA14 impacted Earth the force would be equivalent to about 2.4 megatons of energy (2.4 million tons of TNT), said Yeomans.

There is no danger to the ISS crew and apparently they won’t have any chance to observe it.
“The ISS is not positioned right for observations,” Lindley Johnson, program executive, Near Earth Object Observations Program, NASA Headquarters, Washington, told Universe Today.
“No NASA space-based assets will be making measurements,” Lindley told me. “The asteroid is moving to fast.”
However, radar astronomers do plan to take images around eight hours after the flyby using the Goldstone antenna in California’s Mojave Desert, which is part of NASA’s Deep Space Network.
Some skilful and knowledgeable Earthlings might have a chance to see the asteroid hurtling by with binoculars or a small telescope.
“The asteroid will be observable in the dark sky in Eastern Europe, Asia and Australia, achieving about 7.5 magnitude, somewhat fainter than naked eye visibility,” explained Yeomans. “Closest approach will be over Indonesia.”
Astronomers at the La Sagra Sky Survey program in southern Spain discovered the asteroid in February 2012 just after its last Earth flyby, at a fairly distant 7 Earth-Moon distances. They reported the finding to the Minor Planet Center.
NASA’s NEO group and collaborators in Pisa, Italy then use such data to predict future flight paths and look into past trajectories as well.
Yeomans said that the Feb 15 flyby will be the closest for the next 100 years and its orbit will be perturbed so that it comes back less frequently – changing its orbital class from Apollo to Aten.
Due to its small size and recent discovery, not much is known about the composition of 2012 DA14. It might be silicate rock.
Small space rocks hit Earth on a daily basis amounting to about 100 tons. Car sized rocks hit weekly.
