Since their first mission in June 2010, rockets from the Falcon 9 family have been launched 51 times. Of these, 49 missions were successful, ISS cargo vessel CRS-7 was destroyed in flight, and one mission placed Dragon CRS-1 in the correct orbit but failed to deliver a secondary payload. Additionally, one rocket exploded on the launch pad in a pre-flight test, destroying the Amos-6 satellite. Designed and operated by private manufacturer SpaceX, the Falcon 9 rocket family includes the retired versions Falcon 9 v1.0, v1.1 and v1.2 "Full Thrust", the current "Full Thrust Block 4" upgrade and Falcon Heavy, and the in-development Falcon 9 Block 5. The Falcon design features reusable first-stage boosters, landing either on a ground pad near the launch site, or on a drone ship at sea. Falcon 9 was the first rocket to land propulsively after delivering a payload to orbit. This achievement is expected to significantly reduce launch costs. (Full list...)
