Falcon 9 launches TESS as seen from KSC Press Site (members only)

Watch a zoomed in view of the Falcon 9 rocket with the first Crew Dragon capsule atop, briefly fire its engines for a crucial pre-launch test on Jan. 24, 2019 at launch pad 39A at the Kennedy Space Center.

The spacecraft named PACE (Plankton, Aerosol, Cloud, ocean Ecosystem) has a nominal operating life of three years with the amount of fuel to potentially have it last a decade. It’s set to launch onboard a Falcon 9 rocket on Tuesday, Feb. 6.

SpaceX’s final Falcon 9 launch of the year carried a classified payload for the National Reconnaissance Office, the U.S. government’s spy satellite agency. SpaceX aborted a launch attempt Thursday morning to assess a second stage sensor reading, but the Falcon 9 successfully lifted off from the Kennedy Space Center at 9 a.m. EST (1400 GMT) Saturday. The rocket’s stage landed back at Cape Canaveral eight minutes later.
