The SpaceX Dragon cargo spacecraft waved off its planned rendezvous with the International Space Station at 3:25 a.m. EST. Dragon’s onboard computers triggered the abort after recognizing an incorrect value in navigational data about the location of Dragon relative to the space station. Flight controllers immediately began planning for a second rendezvous attempt on Thursday, Feb. 23.
The spacecraft is in excellent shape with no issues, and the crew aboard the space station is safe. The next rendezvous attempt is targeted for Thursday morning. NASA TV coverage will begin at 4 a.m. with grapple expected around 6 a.m. Installation coverage will begin at 8 a.m. Watch live on NASA TV and online at: http://www.nasa.gov/live.
The hatches between Dragon and station were opened at 2:27 p.m. EDT Wednesday, July 20. The crew entered to document the interior and will begin unloading cargo this afternoon.
The spacecraft delivered nearly 5,000 pounds of science, hardware and supplies, including instruments to perform the first-ever DNA sequencing in space, and the first of two identical international docking adapters (IDA). The IDAs will provide a means for commercial spacecraft to dock to the station in the near future as part of NASA’s Commercial Crew Program.
Dragon is scheduled to depart the space station Aug. 29 when it will return critical science research back to Earth. It is the second cargo spacecraft to arrive on station this week. On Monday, July 18, a Russian ISS Progress 64 cargo craft docked to the Pirs docking compartment of the space station at 8:22 p.m., where it will remain for about six months.
