SpaceX has released a cool video (above) recapping the mission highlights of the historic May 22 blastoff of the firm’s Falcon 9 rocket with the Dragon spacecraft that went on to become the first privately developed vehicle in history to successfully dock to the International Space Station (ISS) on May 25, 2012.
Dragon was captured with a robotic arm operated by astronauts Don Pettit and Andre Kuipers working in tandem aboard the ISS as it approached the massive orbiting lab complex and was then berthed at an Earth facing port.
Dragon was the first US spacecraft to attach to the ISS since the retirement of NASA’s Space Shuttle program last July 2011 following the STS-135 mission of shuttle Atlantis. The 14.4 ft (4.4 meter) long resupply vehicle delivered over 1000 pounds of non-critical gear, food, clothing and science equipment to the ISS.
After spending six days at the ISS, the Dragon undocked and splashed down in the Pacific Ocean some 560 miles off the coast of California on May 31, 2012.

The Falcon 9 rocket and Dragon cargo carrier were designed, developed and built by Hawthorne, Calif., based SpaceX Corporation, founded in 2002 by CEO and Chief Designer Elon Musk.
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. The first operational Dragon CRS mission is slated to blast off around October 2012.

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.”

The historic flight of the first private spaceship to ever connect to the International Space Station (ISS) has entered its waning hours and by all accounts it’s been a resounding success thus far ahead of the imminent return trip to Earth.
All objectives have been fully accomplished and all that remains is for the unmanned Dragon cargo capsule to be detached from the huge outpost early Thursday morning, May 31, following by a mission ending splashdown and ocean recovery off the coast of California some 6 hours later.
Astronauts living aboard the huge Earth orbiting lab closed the hatches to the SpaceX Dragon capsule earlier today (May 30) and will finish their activities to seal the capsule for a safe departure before going to sleep later today ahead of tomorrow’s momentous final feats on this landmark mission.

NASA and SpaceX described the Dragon’s upcoming unberthing and return to Earth activities at a news media briefing today.
The ISS crew is scheduled to disconnect the Dragon from the Earth-facing Harmony node using the station’s robotic arm at 4:05 a.m. EDT (0805 GMT), said NASA flight director Holly Ridings. They will release the Dragon from the arm’s grip into space at 5:35 a.m. EDT (0935 GMT).
“The Dragon really looks great,” Ridings told Universe Today.
Ridings said that the crew completed virtually “all the cargo [unloading and refilling] operations in a single day on Monday”.
Dragon will fire the first of a series of three small orbit transfer burns starting at 5:36 a.m. EDT (0936 GMT) to back it away from the orbiting lab complex. The big de-orbit burn lasting about 7 minutes is set for 10:51 am, the Dragon trunk will be jettisoned at 11:09 a.m., main chutes deploy at 11:36 a.m. and the splashdown in the Pacific Ocean is due at 11:44 a.m. (1544 GMT) some 490 nautical miles southwest of Los Angeles off the West Coast of California using a flotilla of recovery vessels rented by SpaceX for the ocean retrieval process.
Although SpaceX has demonstrated the capability to safely return Dragon to Earth once before in December 2010, the firm is taking nothing for granted.
“It’s still a very challenging phase of flight,” said SpaceX Dragon Mission Manager John Couluris at the briefing. “Only a few countries have done this so far, so we’re not taking this lightly.”
“It will take about 2 to 3 days to return the capsule to the port of Los Angeles and then to the SpaceX facility in Texas for cargo unloading.”
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 heat shield (made of PICA-X) 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 Dragon arrived at the million pound orbiting space lab on May 25. On May 26, the crew opened the hatches and ‘Entered the Dragon’ for the first time.
Look here for a collection of incredible images snapped by European ISS astronaut Andre Kuipers who berthed Dragon at an open parking port on the ISS after it was snared with the 18 m (58 ft) Canadian robot arm by NASA astronaut Don Pettit.
Ridings said the astronauts used the robot arm to thoroughly inspect the Dragon’s exterior, trunk space and solar arrays.
“The results were very positive and our models were very accurate and match the on orbit Dragon configuration and clearances. On downstream flights we’ll be using Dextre on the end of the robot arm to reach around into the Dragon’s truck and grab payloads out,” Ridings told Universe Today.
Capturing SpaceX's Dragon. With clouds and land forming a backdrop, the SpaceX Dragon commercial cargo craft is grappled by the Canadarm2 robotic arm at the International Space Station. Expedition 31 Flight Engineers Don Pettit and Andre Kuipers grappled Dragon at 9:56 a.m. EDT and used the robotic arm to berth Dragon to the Earth-facing side of the station’s Harmony node at 12:02 p.m. May 25, 2012. Dragon became the first commercially developed space vehicle to be launched to the station to join Russian, European and Japanese resupply craft that service the complex while restoring a U.S. capability to deliver cargo to the orbital laboratory. Dragon is scheduled to spend about a week docked with the station before returning to Earth on May 31 for retrieval. Credit: NASA
Dragon is the world’s first commercial resupply vehicle. It was launched atop a SpaceX built Falcon 9 booster on May 22 from Pad 40 at Cape Canaveral Air Force Station, Florida.
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 several years.
NASA TV will provide live coverage of Dragon’s return to Earth and ocean splash down starting at 2:30 a.m. EDT.

Just how many astronauts can you cram inside a Dragon ? – think Volkswagen Beetle!
Well at least 6 human space flyers can easily fit inside a SpaceX Dragon vehicle, said NASA Astronaut Don Pettit from aboard the ISS during a Q & A session with reporters on Saturday, May 26. The discussion with the media took place only hours after Pettit’s history making hatch opening to the first private space capsule ever to dock at the International Space Station (ISS).
“We’ve already had all 6 people in here for a brief period,” Pettit told Universe Today during the media session on Saturday, soon after the hatch opening. “We haven’t taken any pictures of all 6 [together] yet.”

The three current station residents who played the key roles in the milestone events of grappling the Dragon cargo resupply craft with the station’s robotic arm and parking it at an open port on the Harmony Node 2 module on Friday, May 25, spoke to reporters while floating inside Dragon for about 20 minutes all told – including Pettit, ESA Astronaut Andre Kuipers and newly arrived fellow NASA astronaut Joe Acaba.
“There’s not enough room in here to hold a barn dance, but for transportation of crew up and down through Earth’s atmosphere and into space, which is a rather short period of time, there’s plenty of room in here for the envisioned crews,” Pettit told me while soaring some 400 kilometers (250 miles) above Earth.
Dragon is the world’s first commercial spacecraft to attach to the ISS and was built by SpaceX Corporation, founded in 2002 by CEO and Chief Designer Elon Musk.
All three crew members seemed quite pleased with the Dragon’s layout and quite willing to fly aboard a human rated version in the future. SpaceX is designing Dragon to be capable of carrying 7 passengers in the crew configuration – and it looked spacious to me during the media briefing.

“I spent quite a bit of time poking around in here this morning, just looking at the engineering and the layout, and I’m very pleased,” said Pettit. “It looks like it carries about as much cargo as I could put in my pickup truck. And it’s roomier than a Soyuz, so flying up in a human-rated Dragon is not going to be an issue.”
The gumdrop shaped Dragon capsule is 4.4 meters (14.4 ft) tall, and 3.66 m (12 ft) in diameter. It has an internal pressurized volume of about 350 cubic feet
On this first NASA sponsored test flight to rendezvous and dock at the ISS it 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.
The crew starts unloading Dragon today. It will remain berthed at the million pound orbiting outpost for about 6 days until it is detached on May 31 for a return trip to Earth and splashdown and retrieval in the Pacific Ocean a few hundred km (mi) off the coast of California.
The Dragon launched flawlessly atop a SpaceX built Falcon 9 booster on May 22 from Pad 40 at Cape Canaveral Air Force Station, Florida.
Since the forced retirement of NASA’s Space Shuttle fleet in July 2011 and for at least the next 3 to 5 years, the only way U.S. astronauts can reach the ISS is aboard ferry flights on the cramped three person Russian Soyuz capsule at a cost of some $60 million per seat to U.S. taxpayers.
SpaceX is one of four private companies receiving NASA funding under the Commercial Crew and Cargo Program and seeking to develop commercial “space taxis” to low Earth orbit.
A human-rated Dragon is one of the vehicles engaged in the on-going competition and vying for a NASA contract. But the first crewed flight to restore US human spaceflight capability has been delayed by years because of repeated slashes to NASA’s budget by the US Congress.
NASA now estimates that the first space taxi – possibly the SpaceX Dragon – won’t fly until about 2017.

This week and this week only you can see the dawn of the new Commercial Space Era with your own eyes – it’s soaring above your head a mere 400 kilometers (250 miles) away. All you have to do is a quick search, hope for clear skies and traipse outside.
Following the historic attachment of the maiden commercial Dragon cargo carrier to the Harmony node on the International Space Station (ISS) on May 25, the massive orbiting laboratory will be shining just a little bit brighter and prouder as it steaks overhead across the sky at 17,500 MPH (32140 KPH).
Dragon and ISS are literally trailblazing the pathway to the new Commercial Space Era for all to see.
So, for a limited time only between right now and the scheduled May 31 undocking of the SpaceX Dragon spacecraft from the ISS there will be occasional viewing opportunities to catch the dynamic duo speeding merrily across the night time sky.
And the station crew of 6 astronauts and cosmonauts living aboard just opened the hatch from the ISS and “Entered the Dragon” earlier today, May 26 – To make it even more special !
Many folks have never seen an ISS flyover and I can’t think of a better time than now to get started. I’ve held several ISS Sighting star parties in different US States and everyone is thrilled and amazed at how bright the ISS shines – In fact it’s the brightest object in the night sky other than the Sun and the Moon.

For the first time in history space station astronauts have ‘Entered the Dragon’ .. The 1st Private Capsule in Space !
The hatches between the newly arrived Dragon private capsule and the International Space Station’s Harmony Node 2 module were opened at 5:53 a.m. EDT (0953 GMT) today, Saturday, May 26 as the massive complex was flying 407 kilometers (253 miles) over the Tasman Sea between Australia and New Zealand, just west of Auckland.
NASA astronaut Don Pettit had the honors of opening the hatch to the history making first commercial spacecraft to dock at the ISS and begin a busy few days of unloading gear and supplies.
Clearly the crew was eager for the momentous moment because Pettit and Russian cosmonaut Oleg Kononenko, Station Commander floated into Dragon nearly two hours ahead of schedule for the initial inspections.
NASA Astronuat Don Pettit opens hatch to Dragon from Harmony node module on May 26, 2012
Dragon is the first private spacecraft ever to journey and connect to the International Space Station and marked a milestone event in space history when it arrived yesterday morning on May 25. Dragon is the world’s first commercial resupply vehicle and was built by SpaceX Corporation based in Hawthorne, Calif., founded by CEO and Chief Designer Elon Musk.

As a routine precaution to guard against possible contamination and floating debris, Pettit and Kononenko wore protective eye goggles and dust masks over their mouths as they floated and somersaulted playfully through the hatch and all looked in ship shape. They took off the protective gear about 20 minutes later after the air had been well mixed and receiving the all clear from Houston Mission Control.
“There was no sign of any kind of FOD (foreign object debris) floating around in the atmosphere inside,” Pettit reported to Houston upon entering the Dragon. “It kind of reminds me of the cargo capability that I could put in the back of my pickup truck, and the smell inside smells like a brand new car.”

Barely 21 hours ago yesterday morning Pettit snared the Dragon as it was drifting free in space about 10 meters (30 ft) away using the stations 18 m (58 ft) long Canadian-built robotic arm. ESA Astronaut Andre Kuiper then parked Dragon at an open port on the Harmony node. The arm will remain grappled to Dragon throughout most of its docked time.

Dragon is a resupply ship meant to replace some of the cargo duties – both up mass and down mass – fully lost with the forced retirement of NASA’s Space Shuttle fleet last year. It is the first American built spacecraft of any kind to visit the ISS since the departure of the final Shuttle mission STS-135 in July 2011.

The Dragon 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.
The vehicle will be refilled with more than 1400 pounds of science samples, trash and unneeded gear for the trip back home. Dragon is the only ISS cargo resupply vessel that has any significant return to Earth capability since it is equipped with parachutes and a heat shield, unlike the ATV, HTV and Cygnus which burn up on re-entry into the Earth’s atmosphere.
“Dragon is really the main means of carrying cargo back from the space station,” said Elon Musk at a post docking media briefing.

SpaceX is under contract with NASA to conduct a dozen 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.
The first operational Dragon resupply mission to the ISS could launch as soon as September.

The first private spacecraft – named Dragon – was berthed at the International Space Station (ISS) today, May 25, after being dramatically captured by the astronaut crew earlier this morning using the station’s robotic arm in a landmark event in space history – Dragon is the first commercial spacecraft to attach to the International Space Station.
“Capture is confirmed at 9:56 a.m. EDT [1356 GMT],” said Mission Control Houston commentator Josh Byerly, “as the spacecraft [Dragon & ISS] were passing about 251 miles over northwest Australia. Official mission elapsed time was 3 days, 6 hours and 11 minutes and 23 seconds when capture occurred.”
Two hours later, Dragon was successfully attached to the ISS at 12:02 p.m. EDT when 16 motorized bolts on the common berthing mechanism (CBM) latched and locked the cargo vessel to the Harmony module as the giant complex was soaring over the Pacific Northwest region of the US – concluding a dramatic day of momentus space spectaculars.
“SpaceX has done it. They are the first private company to launch and dock their own spacecraft at the International Space Station. Dragon has been successfully captured.”
“Looks like we caught a Dragon by the tail !” said a gleeful Astronaut Don Pettit of NASA who plucked the Dragon from space with the robotic arm as it was in free drift about 10 meters from the station.
Today’s successful Dragon capture and docking ushers in a new era in the history of spaceflight and will radically change the way we do business in space from this day forward.
NASA’s goal is to significantly drive 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 – much like happened with the airline industry of last century.

The Dragon cargo resupply capsule is a commercial spacecraft designed and developed by SpaceX and was flawlessly launched atop a Falcon 9 booster from Cape Canaveral, Florida on a historic test flight on May 22 to become the first private vehicle ever to rendezvous and dock at the million pound orbiting space complex.
Following a successful series of close approach rendezvous tests on Thursday, May 24, when it flew to the ISS from behind and below during fly-under maneuvers to within 2.4 km (1.6 mi), the commercial cargo carrier was cleared for final rendezvous, grappling and docking today.
Dragon at 30 m hold point on May 25
This morning at about 7 a.m. EDT Dragon was given permission to enter the so called keep out sphere (KOS) which is 200 meters from the station. KOS is an imaginary circle drawn around the ISS that prevents the risk of collision with the massive orbiting lab complex. The ISS is orbiting some 400 km (250 miles) above Earth.
Dragon utilized a combination of LIDAR laser ranging and thermal imagers sensors to determine distance as it closed in on the ISS to the final hold point about 10 meters (30 ft) away for final capture by two astronauts on board at work stations located inside the Cupola dome maneuvering the stations robotic arm. The Dragon’s thrusters are disabled at the 10 meter point to prevent an accidental firing and any undesired movement leading to a potential collision.
Dragon was commanded by the SpaceX flight control team based in Hawthorne, Calif, to slowly approach the ISS from below, gradually stopping along the way at ever closer hold points (250 m, 200 m, 150 m, 70 m, 30 m, 10 m) to confirm the crafts position and velocity and that all spacecraft navigation systems were functioning properly to insure a safe capture and berthing operation.
Dragon reached the 30 m hold point at about 9:14 a.m. EDT and then had to wait for final approval and before proceeding closer to the station.
Dragon arrived at the final 10 m hold point at about 9:45 a.m.
“Crew is ready for Dragon capture,” said ISS Astronaut Kuipers from the European Space Agency (ESA).
“You have a go for capture,” said Houston Mission control at about 9:49 a.m. EDT

Some stray retro reflections emanating from the external pallet on Japanese Kibo module affected measurements by the Dragons LIDAR system causing a minor 2 hour delay in final approach and grappling as the unit was recalibrated. Indeed one of the LIDAR units was taken offline due to suspect readings but the mission still continued. Since this is a test flight delays are to be expected.
Expedition 31 Flight Engineers Don Pettit and Andre Kuipers worked in tandem using the Canadarm2 robotic arm to reach out and grapple the supply ship shortly before 10 a.m. EDT for berthing to the Earth-facing side of the station’s Harmony node later today.

Pettit successfully grappled the Dragon with the robotic arm at 9:56 a.m. EDT Kuiper accomplished the berthing a few hours later.
Pettit inspected the Dragon’s berthing mechanism with high powered binoculars after the grappling was done and found it to be in good shape for the subsequent joining to the ISS with sign of no damage from micrometeoroids.
“It looks like a clean interface,” said Pettit to Mission Control.

Dragon is scheduled to spend about a week docked with the station before returning to Earth for a parachute assisted splashdown in the Pacific Ocean off the coast of California on May 31 for an ocean retrieval.
For this initial test flight Dragon is loaded with over 460 kg (1100 pounds) of non-critical items such as food, water, clothing as well as research equipment and student science experiments.
The ISS crew expects to open the hatch and enter the Dragon for the first time on Saturday, May 26.
SpaceX has invested about $1.2 Billion in development of the Falcon 9 and Dragon space vehicles and also received about $381 Million in funding from NASA under the Commercial Orbital Transportation Services (COTS) initiative to develop commercial cargo vehicles to resupply the station.
Dragon will partially replace the cargo carrying duties that were totally lost when NASA’s space shuttles were prematurely and forcibly retired by US politicians after the final shuttle mission in July 2011. No American vehicle has visited the ISS since the shuttle shutdown. The US is now fully dependent on the Russians to ferry astronauts to the ISS for at least the next 3 to 5 years or more and the gap continues to grow as NASA’s budget is slashed by visionless politicians.
SpaceX is under contract with NASA to conduct a dozen 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.
The first operational Dragon resupply mission to the ISS is expected later this year, perhaps as soon as late summer.

A mission status briefing was held at 1 p.m. EDT to discuss the day’s activities and all the days momentous events were broadcast live on NASA TV.
The high stakes Dragon mission to the High Frontier has been a resounding success thus far and its importance to NASA’s future and the future of human spaceflight cannot be overstated.

SpaceX has released the picture above of the Earth as seen by a thermal imager that Dragon will use in its upcoming approach to the International Space Station.
The Falcon 9/Dragon duo thundered to space at 3:44 a.m. on May 22 from Space Launch Complex-40 at Cape Canaveral Air Force Station on a historic mission to be the first private spacecraft to dock at the International Space Station (ISS).
Docking is expected on Friday morning May 25 after an intricate series of maneuvering tests are conducted to prove that the Dragon spacecraft can safely approach and dock at the ISS.
Dragon is loaded with about 1200 pounds of supplies on a test flight aimed at showing it can partially replace the cargo carrying duties of the now retired NASA space shuttles.
