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 ...
Block 5 boosters were initially certified for 10 launches [83] which was increased to 15. A "deep-dive" examination has been performed on Falcon 9 B1058 and B1060 after their 15th flight, [ 84 ] and SpaceX certified Falcon 9 boosters for 20 missions.
US law authorizing retaliation against violations of trade agreements Section 301 of the U.S. Trade Act of 1974 (Pub. L. 93–618, 19 U.S.C. § 2411, last amended March 23, 2018) authorizes the President to take all appropriate action, including tariff-based and non-tariff-based retaliation, to obtain the removal of any act, policy, or practice of a foreign government that violates an ...
The Falcon 1e was to be 6.1 m (20 ft) longer than the Falcon 1, with an overall length of 27.4 m (90 ft), but with the same 1.68 m (5 ft 6 in) diameter. Its first stage had a dry mass of 2,580 kg (5,680 lb), and was powered by an upgraded [ 42 ] pump-fed [ 43 ] Merlin 1C engine burning 39,000 kg (87,000 lb) of RP-1 and liquid oxygen .
For the Commercial Crew Program, NASA requires participating companies to include and test a launch escape system in their crew-carrying vehicles. [7] Prior to this, the last time American crewed spaceflight implemented the capability to escape a rocket during an emergency or anomaly was on the Saturn IB launch vehicle during Skylab missions and Apollo-Soyuz.

C4 Photosynthesis in Space (APEX-09) examines how microgravity affects the mechanisms by which two types of grasses, known as C3 and C4, capture carbon dioxide from the atmosphere. [10] Results could clarify plant responses to stressful environments and inform the design of bio-regenerative life support systems on future missions, as well as ...
The Crew Dragon Pad Abort Test (officially known as the SpaceX Pad Abort Test) [1] was a spacecraft test conducted by SpaceX on 6 May 2015 from the Space Launch Complex 40 (SLC-40) at Cape Canaveral Air Force Station, Florida.
