4K Video: The launch of Crew 4 as seen from the press site

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.

After completing a dress rehearsal for launch day over the weekend, the four astronauts gearing up for liftoff Thursday on a SpaceX Falcon 9 rocket are in good spirits and spending time with their families in Florida before leaving the planet for a six-month expedition on the International Space Station. Forecasters with the U.S. Space Force’s 45th Weather Squadron predict an 80% chance of acceptable weather for launch early Thursday.

Three of Planet’s commercial SkySat Earth-imaging spacecraft will ride to space on top of a stack of SpaceX Starlink satellites next month aboard a Falcon 9 rocket, and three more will hitch a ride on another SpaceX mission later this summer.
