SpaceX CRS-7, also known as SpX-7, [1] was a private American Commercial Resupply Service mission to the International Space Station, contracted to NASA, which launched and failed on June 28, 2015. It disintegrated 139 seconds into the flight after launch from Cape Canaveral , just before the first stage was to separate from the second stage. [ 2 ]
Rockets from the Falcon 9 family have a success rate of 99.34% and have been launched 458 times over 15 years, resulting in 455 full successes, two in-flight failures (SpaceX CRS-7 and Starlink Group 9–3), one pre-flight failure (AMOS-6 while being prepared for an on-pad static fire test), and one partial failure (SpaceX CRS-1, which delivered its cargo to the International Space Station ...
The mission will enter a low Earth orbit (between 425 and 450 km (264 and 280 mi)) with a polar inclination (90°), allowing it to fly over both of Earth's poles. It will aim to observe and study aurora-like phenomena such as STEVE and green fragments and conduct experiments on the human body, including the first X-ray of a human in space. [ 3 ]
The refurbished booster featured a record 2.5 months period turnaround from its original launch of TESS, a record held until February 2020, with the Starlink L4 mission. The fastest previous was 4.5 months. This was the last flight of a Block 4 booster, which was expended into the Atlantic Ocean without landing legs and grid fins. [331] 58 22 ...

90.0 minutes PharmaSat Risk Evaluation Satellite (or PRESat ) nanosatellite , for NASA , was about the size of a loaf of bread, weighed about 4.5 kg (9.9 lb) and was constructed in just six months.
The Falcon 9 v1.0 first stage was used on the first five Falcon 9 launches, and powered by nine SpaceX Merlin 1C rocket engines arranged in a 3x3 pattern. Each of these engines had a sea-level thrust of 556 kN (125,000 pounds-force) for a total thrust on liftoff of about 5,000 kN (1,100,000 pounds-force).
On January 2, 2010, the second stage of the Falcon 9 vehicle was test fired for the full duration required for orbital insertion, 345 seconds. By late February, the launch vehicle had been assembled and raised to its vertical position on the launch pad at Cape Canaveral Air Force Station Space Launch Complex 40 (SLC-40), [ 6 ] having been ...
