We’re sure going to miss Don Pettit’s and Andre Kuipers’ reports and images from the International Space Station. Pettit, Kuipers and Russian Commander Oleg Kononenko undocked from the International Space Station and returned safely to Earth on July 1, wrapping up their six-and-a-half-month mission in orbit.
They landed in their Soyuz TMA-03M spacecraft in Kazakhstan at 08:14 a.m. UT (2:14 p.m. local time) after undocking from the space station’s Rassvet module at 04:47 UT. This video shows a great view of the Soyuz slowly drifting down (it’s interesting to see the parachute undulate, looking almost like a jellyfish!) and then visible are the breaking thrusters firing just a second before the hard landing.
The trio originally arrived at the station back on Dec. 23, 2011, and during this mission spent a total of 193 days in space, 191 of which were aboard the station.
During their expedition, the crew supported more than 200 scientific investigations involving more than 400 researchers around the world. The studies ranged from integrated investigations of the human cardiovascular and immune systems to fluid, flame and robotic research. They also were part of the team that successfully berthed the first commercial spacecraft to visit the ISS, the SpaceX Dragon capsule.
Before leaving the station, Kononenko handed over command of Expedition 32 to the Russian Federal Space Agency’s Gennady Padalka, who remains aboard the station with NASA astronaut Joe Acaba and Russian cosmonaut Sergei Revin. NASA astronaut Sunita Williams, Russian cosmonaut Yuri Malenchenko and Japan Aerospace Exploration Agency astronaut Akihiko Hoshide will join them July 17. Williams, Malenchenko and Hoshide are scheduled to launch July 14 from the Baikonur Cosmodrome in Kazakhstan.
During Expedition 31, Pettit used household objects aboard the station to perform a variety of unusual physics experiments for the video series “Science Off the Sphere,” like his recent video showing water balloons in space. Through these demonstrations, Pettit showed more than a million Internet viewers how space affects scientific principles.
On June 25, Pettit reached a milestone: spending one cumulative year in space, combining his time in orbit on Expedition 6, Expedition 30/31 and the STS-126 space shuttle Endeavour flight to the station in November 2008. Pettit now has 370 days in space, placing him fourth among U.S. space fliers for the longest time in space.
Kuipers conducted over 50 scientific experiments for ESA, and shared, almost daily, images and reports of his stay in space. The next ESA astronaut to board the Space Station is Luca Parmitano of Italy, who will fly on Soyuz TMA-09M in 2013 as member of Expedition 36/37.
At 54.6 million km away at its closest, the fastest travel to Mars from Earth using current technology (and no small bit of math) takes around 214 days — that’s about 30 weeks, or 7 months. A robotic explorer like Curiosity may not have any issues with that, but it’d be a tough journey for a human crew. Developing a quicker, more efficient method of propulsion for interplanetary voyages is essential for future human exploration missions… and right now a research team at the University of Alabama in Huntsville is doing just that.
This summer, UAHuntsville researchers, partnered with NASA’s Marshall Space Flight Center and Boeing, are laying the groundwork for a propulsion system that uses powerful pulses of nuclear fusion created within hollow 2-inch-wide “pucks” of lithium deuteride. And like hockey pucks, the plan is to “slapshot” them with plasma energy, fusing the lithium and hydrogen atoms inside and releasing enough force to ultimately propel a spacecraft — an effect known as “Z-pinch”.
“If this works,” said Dr. Jason Cassibry, an associate professor of engineering at UAH, “we could reach Mars in six to eight weeks instead of six to eight months.”
The key component to the UAH research is the Decade Module 2 — a massive device used by the Department of Defense for weapons testing in the 90s. Delivered last month to UAH (some assembly required) the DM2 will allow the team to test Z-pinch creation and confinement methods, and then utilize the data to hopefully get to the next step: fusion of lithium-deuterium pellets to create propulsion controlled via an electromagnetic field “nozzle”.
Although a rocket powered by Z-pinch fusion wouldn’t be used to actually leave Earth’s surface — it would run out of fuel within minutes — once in space it could be fired up to efficiently spiral out of orbit, coast at high speed and then slow down at the desired location, just like conventional rockets except… better.
“It’s equivalent to 20 percent of the world’s power output in a tiny bolt of lightning no bigger than your finger. It’s a tremendous amount of energy in a tiny period of time, just a hundred billionths of a second.”
– Dr. Jason Cassibry on the Z-pinch effect
In fact, according to a UAHuntsville news release, a pulsed fusion engine is pretty much the same thing as a regular rocket engine: a “flying tea kettle.” Cold material goes in, gets energized and hot gas pushes out. The difference is how much and what kind of cold material is used, and how forceful the push out is.
Everything else is just rocket science.
Read more on the University of Huntsville news site here and on al.com. Also, Paul Gilster at Centauri Dreams has a nice write-up about the research as well as a little history of Z-pinch fusion technology… check it out.

The 2nd of the US Air Force’s top secret X-37B unmanned, reusable mini shuttles safely landed on Saturday, June 16, at 5:48 a.m. Pacific local time at Vandenberg Air Force Base, California to conclude a record setting classified 469 day experimental test flight in Earth orbit.
This was the first flight of OTV-2 and the second flight of the military’s classified X-37B Orbital Test Vehicle (OTV) test program for the U.S. Air Force Rapid Capabilities Office.
The reusable space plane is designed to be launched like a satellite and land on a runway like an airplane and NASA space shuttle. The X-37B is one of the newest and most advanced reentry spacecraft.
Here is the YouTube landing video released by the US Air Force:
OTV-2 was launched atop a United Launch Alliance Atlas V booster from Cape Canaveral Air Force Station, Fla., on March 5, 2011.
About 18 minutes after launch, the Air Force imposed a news blackout on the classified mission. Details about the cargo and experiments loaded aboard the Air Force orbital space plane are shrouded behind a veil of military security.
It is not known if the X-37B conducted reconnaissance activities during the test flight. It does have the capability to deploy satellites in space
The Air Force says the primary mission goal was to check out the vehicles capabilities and testing the ability to send experiments to space and return them safely.

The mission duration of well over one year far exceeded the 220-day mission duration of the first OTV craft and tested additional capabilities. Two OTV vehicles have been built by Boeing. The first craft, known as OTV-1, was the United States’ first unmanned vehicle to return from space and land on its own.
Previously, NASA space shuttles piloted by astronauts were the only space vehicles that had demonstrated the capability of returning to Earth and being reused.
“The vehicle was designed for a mission duration of about 270 days,” said Lt. Col. Tom McIntyre, the X-37B program manager in an Air Force statement. “We knew from post-flight assessments from the first mission that OTV-1 could have stayed in orbit longer. So one of the goals of this mission was to see how much farther we could push the on-orbit duration.”
The 11,000 pound state-of -the art reusable OTV space plane was built by Boeing and is about a quarter the size of a NASA space shuttle. It was originally developed by NASA but was transferred to the Defense Advanced Research Projects Agency (DARPA) in 2004.
“With the retirement of the space shuttle fleet, the X-37B OTV program brings a singular capability to space technology development,” McIntyre said. “The return capability allows the Air Force to test new technologies without the same risk commitment faced by other programs”
Among the cutting-edge technologies tested were the auto de-orbit capability, thermal protection tiles, and high-temperature components and seals.
“The X-37B’s advanced thermal protection and solar power systems, and environmental modeling and range safety technologies are just some of the technologies being tested,” said McIntyre. “Each mission helps us continue to advance the state-of-the-art in these areas.”

OTV-1 may lift off as early as October 2012 from Cape Canaveral.
“We look forward to the second launch of OTV-1 later this year and the opportunity to demonstrate that the X-37B is an affordable space vehicle that can be repeatedly reused,” said Paul Rusnock, Boeing vice president of Government Space Systems.

The Chinese government has announced they will launch three taikonauts sometime in mid-June 2012, on the first manned mission to dock with their orbiting experimental module, and confirmed again that the crew might include China’s first female space traveler. A rocket carrying the Shenzhou 9 spacecraft was moved to a launch pad in China’s desert northwest over the weekend, China’s Xinhua News Agency reported.
The three-member crew will dock with and live inside the Tiangong 1 (or Heavenly Palace-1) orbital module launched last year. No word on how long the mission will be. We reported in March that the crew possibly could include a woman, and Niu Hongguang, deputy commander-in-chief of the country’s manned space program, said the final selection would depend on conditions nearer the time of launch.
This type of late announcement of the crew is not unprecedented – in the past, China’s space program has named the crew for the next mission just a few days before launch.
From previous reports, China picked two women and five men from thousands of candidates to become the second batch of seven astronaut trainees in 2010. Both of the women were former fighter jet pilots.
“The manned space program would not be complete without women’s participation,” Jiao Weixin, an earth and space scientist with Peking University, was quoted as saying.
China launched their first human mission in 2003. They have launched two other human missions, one of which included a space walk in 2008.
Zhou Jianping, chief designer of China’s human space program, said that the mission will be “a significant step in China’s space history”, because it’s the first time for a Chinese spacecraft to send astronauts into a space lab, instead of just carrying them to circle the Earth as in the previous three manned missions, the Chinese Daily reported.
During the flight, one crew member will remain aboard the Shenzhou 9 “as a precautionary measure in case of emergency” while the others enter Tiangong 1, Xinhua said.
We’ll keep you updated on any announcements of the crew or when the launch will take place.
The Chinese government last year announced a 5-year plan for space exploration that includes collecting samples from the Moon by 2016.

NASA’s Space Shuttle Enterprise magnificently completed her final mission by making a historic landing on the deck of a retired aircraft carrier berthed in Manhattan- the Intrepid – as the first and only space shuttle to ever do so on a once-in-history spectacle befitting the Big Apple.
But instead of a piloted landing by air, Enterprise arrived afloat, atop a seagoing barge and was then hoisted and gently lowered for touch down on top of the Intrepid’s flight deck by a humongous seagoing crane accompanying the shuttle on a second barge at 4 p.m. EDT on Wednesday, June 6.
The Intrepid Sea, Air and Space Museum is the permanent new home of the Enterprise, NASA’s prototype shuttle – built in 1976 – that was used for a series of critical atmospheric approach and landing tests in the late 1970’s and that paved the way for building all the five shuttle orbiters that followed and the first launch by the Columbia in April 1981.

Enterprise embarked on a long and winding road to reach the Intrepid which I witnessed at points along the way. First she flew piggyback on top of NASA’s specially modified 747 Jumbo Jet from Dulles International Airport for a triumphant fly over tour of the New York Metropolitan region on April 27 before touching down at John F. Kennedy (JFK) International Airport.
Enterprise had been on public display at the Smithsonian’s National Air & Space Museum Annex in Virginia since 2003.
Then the shuttle took a two day cruise on June 3 and June 6, towed by a tugboat; departing from JFK on June 3 and voyaging through New York Harbor to the Statue of Liberty before making an intermediate stop at a port in Bayonne, New Jersey to switch to another larger barge. Along the way the orbiter suffered some minor damage to the right wing tip when wind gusts caused her to scrape against a railroad bridge.
After a 24 hour postponement due to poor weather, a repaired shuttle Enterprise at last put out to sea again on Wednesday morning, June 6, at about 9:45 a.m. for the very last time on the final leg of her thrilling final voyage.

Enterprise took one last beauty ride past the Statue of Liberty, Ground Zero and the Freedom Tower before sailing North up the Hudson River and past the Empire State Building on Manhattan’s West Side; enjoyed by throngs of onlookers and space enthusiasts lining the shores of New York and New Jersey.
She arrived at the Intrepid, located at Pier 86 at 46th Street and 12th Avenue, at about 1 p.m. accompanied by a flotillia of police and water spraying fire boats, ferries , sailboats and pleasure craft.
The giant lifting crane was maneuvered into position in between the Intrepid and Enterprise.
Over the next three hours, technicians carefully attached a yellow steel harness sling to the 150,000 pound orbiter at four points, two in the front and two in the rear. This was the same sling used to lift Enterprise onto and off the back of the 747 jet.
The 240 foot crane used to hoist Enterprise is the same one used to lift the US Airways jet piloted by hero captain Chesley “Sully” Sullenberger out of the Hudson after an emergency water landing near the same exact spot in January 2009 – where all the passengers and crew on board miraculously survived.

The dramatic pluck of the 75 ton Enterprise off the Weeks Marine barge started around 3:45 p.m. as the winds were gently gusting. Enterprise was raised some 75 feet and rotated nearly 180 degrees so her nose faced directly towards the Hudson River and the beautiful city and cliffs of Weehauken, in Hudson County, New Jersey, where I was watching and photographing from. Enterprise came to rest with wheels down around 4:02 p.m., pretty much exactly on time.
Finally the yellow sling was detached around 6 p.m. and Enterprise was dramatically exposed on the deck of the Intrepid in a beautiful sight for all to see.
But that gorgeous deck view didn’t last long because the museum quickly covered Enterprise with an inflatable pavilion to protect the delicate and precious orbiter from the weather and flying debris – and gawkers looking for free.
To see the Enterprise in all her glory now, you’ll have to pay $22 for admission to the museum and an extra $6 for the shuttle – or check my deck top photo below.

The museum is hastily constructing a temporary, climate controlled “Space Shuttle Pavilion” to house Enterprise. She will be open for public display starting on July 19.
Enterprise is named after the fictional starship in the world renowned and beloved TV science fiction series – “Star Trek”.

Reality TV goes to Mars! Dutch entrepreneur Bas Lansdorp is leading a group visionaries and businesspeople who want to send four humans to Mars by 2023, and they say they can achieve their goal at an estimated cost of $6 billion USD. How can they do it? By building it into a global media spectacle. And oh, by the way, this will be a one-way trip.
“Who would be able to look away from an adventure such as this one?” asks Lansdorp in his bio on the Mars One website. “Who wouldn’t be compelled to watch, talk about, get involved in the biggest undertaking mankind has ever made? The entire world will be able to follow this giant leap from the start; from the very first astronaut selections to the established, independent village years later. The media focus that comes with the public’s attention opens pathways to sponsors and investors.”
The difference between this mission and the one proposed by Jim McLane back in 2008 is that McLane wanted to send just one person to Mars.
However, the Mars One group says that once the first trip is successful and Mars becomes developed, it will be “much easier to build the returning rocket there.”
In a Q&A on reddit, Lansdorp said the biggest challenge will be financing.
“We have estimated, and discussed with our suppliers that it will cost about 6 billion US$ to get the first crew of four people to Mars. We plan to organize the biggest media event ever around our mission. When we launch people to Mars and when they land, the whole world will watch. After that a lot of people will be very interested to see how ‘our people on Mars’ are doing.”
But the big challenge is that the biggest expenditures will be building the equipment before they send people to Mars. “This is why we are building a very strong technical case now. If we can convince sponsors and investors that this will really happen, then we believe that we can convince them to help us finance it,” Lansdorp said.
As far as technologies, Mars One expects to use a SpaceX Falcon 9 Heavy as a launch vehicle, a transit vehicle/space habitat built by Thales Alenia Space, a variant on the SpaceX Dragon as the lander, an inflatable habitat built by ILC Dover, a rover vehicle by MDA Space Missions, and Mars spacesuits made by Paragon.
The project website says “no new technologies” will be needed, but does any space agency or company really have a good handle on providing providing ample air, oxygen, energy, food and water for extended (lifetimes?) periods of time? Instead, the website provides more details on FAQ’s like, What will the astronauts do on Mars? Why should we go to Mars? Is it safe to live on Mars? How does the Mars base communicate with Earth? And the Mars One team emphasizes that this can be done with current technology. However, no one really knows how to land large payloads on Mars yet, so at least some development will be required there.
Who will go? Later this year they will begin to take applications and eventually 40 people will take part in a rigid, decade-long training program (which sounds very expensive) where the ‘contestants” will essentially be voted off the island to get to the final four astronauts. The selection and training process will be broadcast via television and online to public, with viewers voting on the final selected four.
It’s an intriguing proposition, but one filled with technological hurdles. I’ve just finished reading Ben Bova’s “Mars,” so I’m also thinking the Mars One folks will need to be on the lookout for micrometeorite swarms.

Enterprise, post boo-boo and postponed a day by rainy weather, should arrive at the Intrepid today !
The final leg of the final voyage of Space Shuttle Enterprise is due to conclude on Wednesday, June 6 with a journey by barge up the Hudson River on Manhattan’s West Side to her permanent new home at the Intrepid Sea, Air and Space Museum.
And it can’t come soon enough. As might be expected, Barge rides for Space Shuttles can be both visually stunning and downright perilous.
And for the initial seagoing leg of Enterprise’s journey on Sunday, June 3, it was a mixture of both – mostly thrilling (as I can attest) plus a few bad moments
During Sunday’s transit of Enterprise across the New York skyline, the shuttle suffered some minor damage to the wing tip (see photo above) soon after she set sail.
According to collectSpace.com, Enterprise grazed a New York railroad bridge when wind gusts caused the shuttle loaded aboard the Weeks Marine barge to veer off course.
“Mother nature did not smile on us. Just as the barge entered the railroad bridge, the wind caught it and pushed the right wing into the bridge abutment. Fortunately, the damage seems to be cosmetic, limited to the foam that covered the wingtip. No structure or mechanisms appear to have been damaged,” wrote Dennis Jenkins who was aboard the barge with Enterprise.

The remainder of the voyage went off without a hitch and was enjoyed by throngs of onlookers including myself.
I caught some shots of the damage late in the day as the crew from Weeks Marine was towing Enterprise into port for the night.
Workers have already repaired Enterprise, the Intrepid said in a statement.
On Wednesday morning, Enterprise is due to set sail atop a barge from Bayonne, New Jersey from where she docked on Sunday, June 3 on the initial leg of her seagoing journey to her permanent new home.
Enterprise is scheduled to depart from Bayonne at 10:15 am and then make her way North passing the Statue of Liberty at approximately 10:52 am and Ground Zero at about 11:30 am says the Intrepid. She will reach the Museum at around 12:30 pm and be hoisted onto the flight deck later in the day – all of which is weather permitting.
On July 19, Enterprise will be opened to public viewing

On Sunday, June 3, throngs of New Yorkers, Jerseyites and more witnessed one of those ultra rare astronomical events – The Space Shuttle Enterprise’s Transit of the NYC Skyline !
NASA’s Space Shuttle Enterprise completed the first leg of her final voyage – a seagoing journey by barge from John F. Kennedy (JFK) International Airport across New York Harbor and to her final resting place at the Intrepid Sea, Air and Space Museum on the Hudson River on Manhattan’s West Side.
To prepare for the watery journey, Enterprise was hoisted by crane onto the Weeks Marine barge on Saturday, June 2. On Sunday, the barge with Enterprise firmly in place was moved by tugboat out of JFK and along the shores of Queens and Brooklyn. It passed by the Marine Parkway-Gil Hodges Memorial Bridge at about 3:30 p.m. and Coney Island at about 4:19 p.m.

At last the orbiter approached shortly after 5 p.m. along with a small flotilla of guard and guide ships. She passed gracefully under the gorgeous and lengthy span of the Verrazano Narrows Bridge and past the humongous pylons, right on time at around 5:30 p.m. – as enormous Cruise Ships swarming with thousands of agog passengers steamed by the comparatively tiny space shuttle. Sailboats and pleasure craft also sailed close by for exquisite views.
Enterprise put on a fantastic, once-in-a-lifetime spectacle, enjoyed by the gathered multitudes all along the route and she sailed past Manhattan’s shore and skyscrapers and on towards the Statue of Liberty in New York Harbor.
Ultimately, Enterprise docked late in the evening at Port Elizabeth, Bayonne, New Jersey – at a different location than had been announced – with a direct view of the Statue of Liberty and the southern tip of the gorgeous Manhattan skyline, home to the Freedom Tower currently in the final stages of construction and now the tallest building in New York City.

Inclement NYC weather has postponed the second part of the two part barge journey to the Intrepid museum from Tuesday tentatively to Wednesday, June 6. Enterprise will again journey past the Statue of Liberty and then up the Hudson River to her new home at the Intrepid, where she will be hoisted by crane onto the flight deck of the aircraft carrier – when the weather safely allows.

Millions of gawkers watched as Enterprise arrived in New York on April 27, loaded on the back of NASA’s specially modified 747 Jumbo Jet for her very last flight from the Smithsonian’s National Air and Space Museum at Dulles International Airport.
Read more about the April 27 flyover arrival of Enterprise in NYC, in my article here:
The Enterprise was a prototype shuttle and the first of NASA’s Space Shuttles orbiters to be built and was used in landmark approach and landing tests that paved the way for the entire Shuttle fleet and the first shuttle launch in 1981 from the Kennedy Space Center in Florida.

Dragon splashed down successfully on May 31, 2012 at 11:42 a.m. EDT in the Pacific Ocean off the west coast of California. In a carefully timed sequence of events, dual drogue parachutes deploy at 45,000 feet to stabilize and slow the spacecraft. Full deployment of the drogues triggers the release of the main parachutes, each 116 feet in diameter, at about 10,000 feet, with the drogues detaching from the spacecraft. Main parachutes further slow the spacecraft's descent to approximately 16 to 18 feet per second. Credit: Michael Altenhofen

Concluding a perfectly executed and history making test flight, the first private spacecraft ever to visit and dock at the International Space Station (ISS) performed a picture perfect splashdown at 11:42 a.m. EDT (1542 GMT) today, May 31, in the Pacific Ocean, off the west coast of Baja, California, some 560 miles southwest of Los Angeles to cap the opening to a historic new Era in Space Exploration.
Dragon is the linchpin in NASA’s bold Commercial Crew and Cargo program aimed at significantly driving down the cost of transporting cargo and crews to low Earth orbit by using private commercial companies to foster competition and innovation in the free market setting of the new, post-shuttle Era of Commercial Space Transportation.
NASA aircraft were able to transmit live video of the last few minutes of the Dragon’s breathtaking descent, unfurling of the trio of parachutes and ocean splashdown – pretty much on target at 27 degrees latitude and 127 degrees west longitude.
The official mission elapsed time on landing was 9 days, 7 hours and 58 minutes.
Splashdown of the Dragon cargo craft took place barely 6 hours after departing the orbiting lab complex following detachment from the station using the station robotic arm. The ISS astronauts released the craft from the grip of the station’s robot arm at 5:49 a.m. EST (949 GMT) this morning, May 31.

The two spacecraft were soaring some 250 miles (400 km) high above the Indian Ocean east of Africa at the moment of release and departure. Altogether, Dragon spent 5 days, 16 hours and 5 minutes mated to the station.
The gumdrop shaped Dragon capsule is 4.4 meters (14.4 ft) tall, and 3.66 m (12 ft) in diameter and has an internal pressurized volume of about 350 cubic feet .
The Dragon cargo resupply capsule was built by SpaceX and is being retrieved from the ocean by a flotilla of three recovery ships. The ships reached Dragon, detached the chutes and are in the process of recovery. It will take about two days to deliver the craft to the port of Los Angeles where the most critical cargo items will be removed for quick shipment to NASA. The capsule will then be shipped to SpaceX’s McGregor,Texas facility for post-flight evaluation.
Dragon is the world’s first commercial spacecraft whose purpose is to carry supplies to and from the ISS and partially replace the cargo capabilities previously performed by NASA’s now retired fleet of space shuttle orbiters. Dragon was designed, developed and built by Hawthorne, Calif., based SpaceX Corporation, founded in 2002 by CEO and Chief Designer Elon Musk.
“This has been a fantastic day,” said Musk at a post splashdown briefing for reporters. “I want to thank NASA and the whole SpaceX team for an amazing job.”
“I’m really proud of everyone. This really couldn’t have gone better. We’re looking forward to doing lots more missions in the future and continuing to upgrade the technology and push the frontier of space transportation.”
“In baseball terminology this would be a grand slam. I am overwhelmed with joy.”
The de-orbit burn to drop Dragon out of orbit took place precisely on time at 10:51 a.m. EDT for a change in velocity of 100 m/sec about 246 miles above the Indian Ocean directly to the south of India as the craft was some 200 miles in front of the ISS.

The Draco thruster firing lasted 9 minutes and 50 seconds and sent Dragon plummeting through the Earth’s atmosphere where it had to survive extreme temperatures exceeding 3000 degrees F (1600 degrees C) before landing.
The Dragon capsule is the first US vehicle of any kind to arrive at the ISS since the July 2011 forced retirement of NASA’s Space Shuttle Program resulted in the total loss of all US capability to send cargo and humans crews to the massive orbiting outpost.
SpaceX signed a contract with NASA in 2006 to conduct twelve Falcon 9/Dragon resupply missions to carry about 44,000 pounds of cargo to the ISS at a cost of some $1.6 Billion over the next few years.
This was the third test flight of the Falcon 9 rocket and the first test flight of the Dragon in this vastly upgraded configuration with solar panels. A future variant of Dragon will eventually blast US astronauts to space and restore US crew capability – perhaps by 2017 thanks to repeated cuts to NASA’s budget.
Only four entities have ever sent a spacecraft to dock at the ISS – the United States, Russia, Japan and the European Union. SpaceX is the first commercial entity to accomplish the same feat.
The precedent setting Dragon mission has opened a new era in spaceflight by giving birth to the first fully commercial mission to the orbiting space station complex and unlocking vast new possibilities for its utilization in science and exploration.
After a three day chase, Dragon arrived at the ISS on May 25 and was deftly berthed at an open Earth-facing port on the Harmony Node 2 module after being dramatically captured by the astronaut crew using the station’s robotic arm in a landmark event in space history as the Dragon and the ISS were passing about 251 miles above Earth. Capture was confirmed at a mission elapsed time of 3 days, 6 hours and 11 minutes and 23 seconds.
Working in tandem, NASA astronaut Don Pettit and ESA astronaut Andre Kuipers snared the Dragon craft as it was drifting in free space about 10 m (32 ft) away with the 18 m (58 ft) long Canadian robot arm at 9:56 a.m. EDT and parked the first privately built capsule to an open port at 12:02 p.m. EDT on May 25.
The astronauts opened the hatch and ‘Entered the Dragon’ for the first time a day later on May 26 and then proceeded to unload the stowed cargo and refill it for the return trip to Earth.
On this first NASA sponsored Dragon test flight to rendezvous and dock at the ISS, the cargo craft was packed with 460 kilograms (1014 lbs) of non-critical cargo including 306 kg (674 lbs) of food and crew provisions; 21 kg (46 lbs) of science experiment; 123 kg (271 lbs) prepositioned cargo bags to be used for future flights; and 10 kg (22 lbs) of assorted computer supplies and a laptop.
Dragon splashed down successfully on May 31, 2012 at 11:42 a.m. EDT in the Pacific Ocean off the west coast of California. In a carefully timed sequence of events, dual drogue parachutes deployed at 45,000 feet to stabilize and slow the spacecraft. Full deployment of the drogues triggers the release of the main parachutes, each 116 feet in diameter, at about 10,000 feet, with the drogues detaching from the spacecraft. Main parachutes further slow the spacecraft's descent to approximately 16 to 18 feet per second.
Unlike the other Russian, European and Japanese cargo freighters that service the ISS and then disintegrate on reentry, the SpaceX Dragon is uniquely equipped with a state of the art PICA-X heat shield that allows it to plunge safely through the Earth’s atmosphere and survive the fiery temperatures exceeding more than 3000 degrees F (1600 degrees C).

The down mass capability restores another critical capability lost with the forced retirement of NASA’s Space Shuttle orbiters in July 2011. The astronauts filled Dragon with about 620 kilograms (1367 pounds) of science experiments, trash and non-critical items on this historic test flight.
The first operational Dragon resupply mission to the ISS could blast off as early as September, said Alan Lindenmoyer, manager of NASA’s Commercial Crew and Cargo Program.
“We’ll await the final post flight report to make the determination that this was an extremely successful mission. But they should be well on their way to starting [delivery] services,” said Lindenmoyer at the briefing. “Of course, officially we will look at the post flight data and make an official determination. But I would say at this point it looks like 100 percent success.”

History’s first commercial cargo ship ever to visit the International Space Station (ISS) has safely and successfully departed the orbiting lab complex after astronauts released the craft from the grip of the station’s robotic arm at 5:49 a.m. EST (949 GMT) this morning, May 31, 2012 for the return trip to Earth to conclude a precedent setting stay that fully accomplished all objectives.
“Dragon is Free !” announced Josh Byerly, a NASA spokesman at Houston Mission control a short while ago as NASA astronauts Joe Acaba and Don Pettit released the first ever private spacecraft to attach to the ISS into a free drift mode for a fiery plunge through Earth’s atmosphere and splash down in the Pacific Ocean off the coast of Baja California less than 6 hours from now.
“Everything looking safe and sound.”
The two spacecraft were some 250 miles (400 km) high above the Indian Ocean east of Africa at the moment of release and departure. Altogether, Dragon spent 5 days, 16 hours and 5 minutes mated to the station.
A minute later Dragon successfully conducted its first departure burn to back away from the massive orbiting complex followed shortly thereafter by two more short pulsed firings of the capsules thrusters. The last of the three short separation burns took place at 6:02 a.m. EDT.

The Dragon then passed outside the imaginary 200 meter (656 ft) circular zone known as the Keep-Out-Sphere (KOS) and was placed under the exclusive control of SpaceX mission controllers with NASA control duties completed
The next major event is the de-orbit burn scheduled for 10:51 a.m. EDT which is a 100 m/sec burn lasting 9 minutes and 50 seconds. The thruster firing will send Dragon plummeting through the Earth’s atmosphere at 17000 MPH where it must survive temperatures exceeding 3000 degrees F before landing.
Earlier this morning, Acaba and Pettit unhooked the final 16 motorized bolts and latches holding Dragon firmly to the station at the common berthing mechanism and detached Dragon from the station’s Earth facing Harmony node at 4:07 a.m. EDT using the 18 m (58 ft) Canadian robot arm. The astronauts worked at robotic work stations inside the multi-windowed Cupola observation dome.
Dragon Splashdown Zone
The SpaceX Dragon is now headed for a splashdown in the Pacific Ocean at 11:44 a.m. EST (1544 GMT) some 490 nautical miles southwest of Los Angeles off the West Coast of California.
SpaceX has dispatched three recovery vessels to retrieve Dragon from the ocean.
Following launch from Cape Canaveral, Florida on May 22, Dragon arrived at the ISS on May 25 and the astronauts opened the hatch on May 26 and then proceeded to unload the cargo and refill it for the return trip.
Dragon is the world’s first commercial spacecraft and was built by Hawthorne, Calif., based SpaceX Corporation, founded in 2002 by CEO and Chief Designer Elon Musk.
“This is SpaceX’s second demonstration flight under a 2006 Commercial Orbital Transportation Services (COTS) agreement with NASA to develop the capability to carry cargo to and from the International Space Station’” says SpaceX spokeswoman Kirstin Grantham.
“With the first demonstration flight, in December of 2010, Dragon became the first commercial spacecraft to orbit the Earth and safely return. During that mission SpaceX conducted similar recovery operations to retrieve Dragon from a water landing in the Pacific. Demonstration missions are conducted to determine potential issues so that they might be addressed; by their very nature, they carry a significant risk. If any aspect of the mission is not successful, SpaceX will learn from the experience and try again.”
