Hawthorne, CA (SPX) Dec 16, 2011
December 8 2011, marked the one year anniversary of Dragon's first Commercial Orbital Transportation Services (COTS) demonstration flight. The flight made history as SpaceX became the only commercial company to successfully return a spacecraft from orbit. This feat had previously been accomplished only by five nations and the European Space Agency.
We are now preparing the Dragon spacecraft for yet another historic flight - becoming the first commercial vehicle in history to visit the International Space Station (ISS)!
NASA recently announced February 7, 2012, as our new target launch date for the upcoming mission. In addition, NASA officially confirmed that SpaceX will be allowed to complete the objectives of COTS 2 and COTS 3 in a single mission.
This means Dragon will perform all of the COTS 2 mission objectives which include numerous operations in the vicinity of the ISS, and will then perform the COTS 3 objectives.
These include approach, berthing with the ISS, astronauts opening Dragon and unloading cargo, and finally, astronauts closing the spacecraft and sending it back to Earth for recovery from the Pacific Ocean off the coast of California.
This mission marks a major milestone in American spaceflight. While our first missions to the ISS will be to transport cargo, both Falcon 9 and Dragon were designed to ultimately transport astronauts.
Every trip we make to the ISS from this point forward gets us closer to that goal. SpaceX is incredibly excited for what the future holds and as always, we greatly appreciate NASA's continued support and partnership in this process.
The Cots 2/3 Demonstration Mission
Each launch day will have just one narrow liftoff window-no more than a few minutes-in order to synchronize Dragon's flight with the orbit of the ISS. Catching up to the ISS will take from one to three days. Once there, Dragon will begin the COTS 2 demonstrations to show proper performance and control in the vicinity of the ISS, while remaining outside the Station's safe zone.
During the entire time Dragon is in the vicinity of the ISS, Station astronauts will be in direct communication with Dragon and will be able to monitor the spacecraft as well as issue spacecraft commands.
After successfully completing the COTS 2 requirements, Dragon will receive approval to begin the COTS 3 activities, gradually approaching the ISS from the radial direction (toward the Earth), while under constant observation.
Dragon will approach to within a few meters of the ISS, allowing astronauts to reach out and grapple Dragon with the Station's robotic arm and then maneuver it carefully into place. The entire process will take a few hours.
Once in place, Station astronauts will equalize the pressure between the ISS and Dragon, open the hatches, enter the vehicle and begin unloading Dragon's cargo.
After Dragon spends about a week berthed at the ISS, astronauts will reverse the process, loading Dragon with cargo for return to Earth, sealing the hatches, and un-berthing Dragon using the robotic arm.
Dragon will then depart from the ISS and return to Earth within a day or so, and the SpaceX recovery crew will meet it at splash down in the Pacific Ocean off the coast of California.
Preparing For Launch At The Cape
Falcon 9's first stage, second stage, and interstage were integrated and rolled out for two separate wet dress rehearsals in which SpaceX engineers performed the entire countdown sequence up until the moment the engines would be fired.
The Dragon COTS Demo 2/3 spacecraft and trunk have also been delivered to our launch pad and are undergoing final processing for flight.
Build And Fly Your Own Falcon 9 And Dragon Model Rocket
The Falcon 9/Dragon model kit includes a molded nose and tail, along with full color stickers for the body and nose (no painting required). The finished model stands 58 cm (22.8 in) tall. It has molded transparent fins for flight, which can be removed for display. Dual parachutes return the Falcon 9 and Dragon spacecraft separately to Earth.
The model kits are in production and will be made available over Amazon.com in the coming weeks. To reserve one, visit here and add the Falcon 9 and Dragon model to your personal Wish List. You will receive an email as soon as the kits reach the warehouse shelves and are ready to ship.
Thanks to all for your support and stay tuned for more updates on Dragon's first visit to the ISS!
