New research and technology demonstrations for NASA are scheduled to launch aboard the agency’s SpaceX 30th commercial resupply services mission to the International Space Station at 4:55 EDT from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida.
Coverage of launch and docking activities will air live on NASA+, NASA Television, the NASA app, YouTube, and the agency’s website. Learn how to stream NASA TV through a variety of platforms including social media.

SpaceX’s Dragon spacecraft will carry more than 6,000 pounds of cargo, including new science investigations, supplies, and equipment to the international crew aboard the orbiting laboratory. NASA and its partners will send studies aboard the mission on plant metabolism in space and a set of new sensors for free-flying Astrobee robots to provide 3D mapping capabilities. Other research includes a fluid physics study that could benefit solar cell technology and a university project from CSA (Canadian Space Agency) that will monitor sea ice and ocean conditions.
Arrival at the station is scheduled for approximately 7:30 a.m. Saturday, March 23. The SpaceX Dragon spacecraft will dock autonomously to the zenith port of the station’s Harmony module.
