“With a big splash in the Pacific Ocean today, we are reminded American ingenuity is alive and well and keeping our great nation at the cutting edge of innovation and technology development,” NASA Administrator Charles Bolden said. “Just a little over one year after we retired the Space Shuttle, we have completed the first cargo resupply mission to the International Space Station. Not with a government owned and operated system, but rather with one built by a private firm — an American company that is creating jobs and helping keep the U.S. the world leader in space as we transition to the next exciting chapter in exploration. Congratulations to SpaceX and the NASA team that supported them and made this historic mission possible.”

The Dragon capsule will be taken by boat to a port near Los Angeles, where it will be prepared for a return journey to SpaceX’s test facility in McGregor, Texas, for processing. Some cargo will be removed at the port in California and returned to NASA within 48 hours. This includes a GLACIER freezer packed with research samples collected in the orbiting laboratory’s unique microgravity environment. These samples will help advance multiple scientific disciplines on Earth and provide critical data on the effects of long-duration spaceflight on the human body. The remainder of the cargo will be returned to Texas with the capsule.

The ability to return frozen samples is a first for this flight and will be tremendously beneficial to the station’s research community. Not since the space shuttle have NASA and its international partners been able to return considerable amounts of research and samples for

The Dragon launched atop a SpaceX Falcon 9 rocket from Cape Canaveral Air Force Station in Florida, on Oct. 7. It carried 882 pounds of cargo to the complex, including 260 pounds of crew supplies, 390 pounds of scientific research, 225 pounds of hardware and several pounds of other supplies. This included critical materials to support 166 scientific investigations, of which 63 were new. Returning with the Dragon capsule was 1,673 pounds of cargo, including 163 pounds of crew supplies, 866 pounds of scientific research, and 518 pounds of hardware.

The mission was the first of at least 12 cargo resupply missions to the space station planned by SpaceX through 2016 under NASA’s Commercial Resupply Services contract.

SpaceX is one of two companies that built and tested new cargo spacecraft under NASA’s Commercial Orbital Transportation Services (COTS) program. Orbital Sciences is the other company participating in COTS. A demonstration flight of Orbital’s Antares rocket and Cygnus spacecraft to the station is planned in early 2013.

NASA initiatives like COTS and the agency’s Commercial Crew Program are helping develop a robust U.S. commercial space transportation industry with the goal of achieving safe, reliable and cost-effective transportation to and from the space station and low-Earth orbit. In addition to cargo flights, NASA’s commercial space partners are making progress toward a launch of astronauts from U.S. soil in the next 5 years.

While NASA works with U.S. industry partners to develop and advance these commercial spaceflight capabilities, the agency also is developing the Orion spacecraft and the Space Launch System (SLS), a crew capsule and heavy-lift rocket to provide an entirely new capability for human exploration. Designed to be flexible for launching spacecraft for crew and cargo missions, SLS and Orion will expand human presence beyond low-Earth orbit and enable new missions of exploration in the solar system.

Dragon – "The Ice Cream Truck Has Arrived"

At 3:56 AM Pacific Daylight time, Wednesday 10 October, the SpaceX Dragon space craft was successfully grappled by the Canadarm on the International Space Station (ISS). Referring to the fact that Dragon is capable of carrying powered equipment to and from the space station, the space station crew reported that they had captured Dragon and were looking forward to the chocolate-vanilla swirl ice cream in the freezer aboard the space craft.

NASA Gains Breathing Room On Commercial Crew Program

NASA has negotiated a continuation of its successful Space Acts Agreements (SAA) procedures for contracting and funding of the next phase of its Commercial Crew Program (CCP). The SAA has also been the process for NASA’s Commercial Orbital Transportation Services (COTS), which saw the flight of the SpaceX Dragon to the International Space Station (ISS) with cargo, and its return with science experiments and no longer needed space station equipment.

The deal, worked out between NASA Administrator Charles Bolden and the chairman of the House Appropriations subcommittee, Representative Frank Wolf (R-Va), will allow NASA to select 2.5 partners under the CCP using SAA rather than the more restrictive and cumbersome Federal Acquisition Regulation (FAR). Wolf’s statement on his website was followed by a letter from Bolden.

The agreement allows the Commercial Crew Integrated Capability (CCiCAP) phase of CCP to proceed under SAA rules, but then commits NASA to using FAR procedures for certification and procurement of services.

There was also agreement to fund the program at the Senate level of $525 million, although Bolden in his letter urged the conference committee to fund the CCP at a higher level for 2013. The Administration had originally requested $836 million.

Contenders in the Commercial Crew arena include:

  • Space Exploration Technologies Corporation – SpaceX – Dragon
  • Sierra Nevada Corporation – SNC – Dream Chaser
  • Boeing – CST-100
  • Blue Origin – New Shepherd

The Dragon spacecraft successfully completed all mission objectives and floats quietly in the Pacific Ocean off the coast of Mexico following reentry and splashdown.

SpaceX announced:

This morning, at approximately 8:42 AM Pacific/11:42 AM Eastern, Space Exploration Technologies (SpaceX) completed its historic mission when the Dragon spacecraft splashed down safely in the Pacific. The vehicle will now be recovered by boats and start the trip back to land.

Last week, SpaceX made history when its Dragon spacecraft became the first commercial vehicle in history to successfully attach to the International Space Station. Previously only four governments – the United States, Russia, Japan and the European Space Agency – had achieved this challenging technical feat. Dragon departed the space station this morning.

Broadcast quality videos, including footage from the recovery ship will be posted to and high-resolution photos will be posted to as soon as they are available.

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.

NASA Administrator Places Call to ISS Following SpaceX Historic Feat

25 May 2012

WASHINGTON — NASA Administrator Charles Bolden offered his congratulations to the International Space Station Expedition 31 crew and mission flight control teams at NASA’s Johnson Space Center in Houston and SpaceX’s headquarters in Hawthorne, Calif., following Friday’s successful first-time berthing of a commercial company spacecraft, SpaceX’s Dragon, to the space station.

Bolden talked with NASA astronauts Don Pettit and Joe Acaba, and European Space Agency astronaut Andre Kuipers during a call to the space station Friday afternoon live on NASA Television. Bolden told the crew, “You made history today and have firmly locked into place the future direction of America’s space program.”

"We've Got a Dragon by the Tail"

At 9:56 AM EDT (1356 UTC), the Space Station Remote Manipulator System (SSRMS) successfully grappled the Dragon spacecraft. This is the first commercial spacecraft to reach the International Space Station. Additional manipulations are required to berth the Dragon to a docking port.

“Looks like we’ve got a Dragon by the tail,” station flight engineer Don Pettit said moments after grappling the craft over northwest Australia.

Opening of the ports and beginning to unpack the spacecraft will begin tomorrow, Saturday.

The spacecraft is to be loaded with about 1300 pounds of science experiments and other material and returned to Earth on 31 May. Dragon will land in the Pacific, several hundred miles off of Southern California.

SpaceX Commentary on Dragon's Flight Day 3 and the Challenges Ahead

Hawthorne, CA – Today, Space Exploration Technologies (SpaceX) Dragon spacecraft completed key on-orbit tests as part of a historic attempt to be the first commercial company in history to send a spacecraft to the International Space Station.

In the days since SpaceX’s Dragon spacecraft successfully launched from Cape Canaveral, Florida, the vehicle has steadily completed one task after another as it prepares to berth with the International Space Station. Only minutes after the spacecraft separated from the Falcon 9 rocket’s second stage, its solar arrays successfully deployed, providing power to the spacecraft. The door that had been covering sensors needed for proximity operations opened successfully.

On Tuesday and Wednesday Dragon traveled in orbit, firing its thrusters to catch up to the space station. During that time, the vehicle hit a series of milestones. Dragon showed its Absolute Global Positioning System (GPS) is in good working order. The vehicle demonstrated both a pulsed and a full abort. It also demonstrated free drift, floating freely in orbit as it will when grappled by the space station’s robotic arm. And its proximity operations sensors and SpaceX’s COTS UHF Communication Unit (CUCU) are up and running.

Early this morning, Dragon’s thrusters fired, bringing the vehicle 2.4 kilometers below the International Space Station. The vehicle completed two key tests at that distance. Dragon demonstrated its Relative GPS and established a communications link with the International Space Station using CUCU. Astronauts commanded on Dragon’s strobe light to confirm the link worked.

With these tests complete, Dragon has started the trip flying around the space station, returning the spacecraft to its original approach location.

Dragon has been performing well, but the most difficult aspects of the mission are still ahead.

FRIDAY MORNING – Final Approach, Dragon Grapple

Around 2:00 AM Pacific/5:00 AM Eastern NASA will decide if Dragon is GO to move into the approach ellipsoid 1.4 kilometers around the space station. If Dragon is GO, after approximately one hour Dragon will move to a location 250 meters directly below the station. Dragon will then perform a series of maneuvers to show systems are operating as expected. If NASA is satisfied with the results of these many tests, Dragon will be allowed to perform the final approach to the space station.

Sometime around 6:00 AM Pacific/9:00 AM Eastern, astronauts on the space station will grapple Dragon with the space station’s robotic arm and the spacecraft will attach to the station.


If all goes well, at approximately 2:00 AM Pacific/5:00 AM Eastern, the crew will start procedures to open Dragon’s hatch. It will take around 2 hours to complete all operations leading to the hatch opening. Once the hatch is opened, astronauts will enter Dragon for the first time
in space.

All dates and times are approximate and could easily change.

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. Demonstration launches 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.
