Falcon 9 Flight 21 (also known as Jason 3) is a Falcon 9 space launch currently scheduled to occur no earlier than 17 January 2016 from SpaceX' leased California launch facility at Vandenberg AFB.[1][2][3] It will carry to orbit the Jason-3 Earth-observation satellite for NOAA/NASA/CNES.
The launch will be only the second SpaceX launch following the catastrophic failure of a Falcon 9 v1.1 launch vehicle's second stage on Falcon 9 Flight 19 in June 2015, which resulted in the total loss of the mission on that launch. It will also be the final launch of a Block 2 Falcon 9—the Falcon 9 v1.1—although some parts of the rocket body have been reworked following conclusion of the failure investigation.[4]

The Jason-3 mission appeared on the SpaceX manifest as early as July 2013, with a no earlier than launch year of 2015.[5]
A 7-second static fire test of the rocket was completed on 11 January 2016.[6] The test was successful, and the Launch Readiness Review was successfully completed with all parties on 15 January 2015.
Payload
The payload on Flight 21 is an Earth observation satellite named Jason-3, a follow-on to the Ocean Surface Topography Mission (OSTM) (Jason-2). The initial OSTM satellite, Jason-1, was launched in 2001.
Jason-3 is the result of a four-agency international partnership consisting of NOAA, NASA, the French Space Agency CNES (Centre National d’Etudes Spatiales), and EUMETSAT (the European Organization for the Exploitation of Meteorological Satellites). Thales Alenia Space built the spacecraft.
Jason-3 will mass 525 kilograms (1,157 lb) at launch.[7]
Post-mission landing test
Following paperwork filed with US regulatory authorities in 2015,[8] SpaceX confirmed in January that they will attempt a vertical landing controlled-descent flight test of the first stage on the west coast floating landing platform.[9]
In the event, the controlled-descent was successful, and the rocket reached the drone ship at its location roughly 200 miles out in the Pacific Ocean, but the rocket landed hard, a landing leg broke, and the stage recovery attempt was not successful.
This follows the successful eighth test, and first successful landing and booster recovery, on the previous launch in December 2015.[10][11] The controlled-descent through the atmosphere and landing attempt for each booster is an arrangement that is not used on other orbital launch vehicles.[12]
Approximately 9 minutes into the flight, the live video feed from the autonomous drone ship "Just Read the Instructions" went down due to the ship losing its lock on the uplink satellite. Elon Musk later reported that the first stage did successfully soft-land on the ship, but a lockout on one of the landing legs failed to latch and it fell over.[13][14][15]
