Mission

The Geostationary Operational Environmental Satellite-U (GOES-U) is the fourth of the next generation of geostationary weather satellites, known as the GOES-R series. The four satellites of the series provide advanced imaging with increased spatial resolution and faster coverage for more accurate forecasts, real-time mapping of lightning activity, and improved monitoring of solar activity. Once GOES-U reaches orbit, it will be renamed GOES-19.

Launch Provider

SpaceX

Commercial · United States of America · Founded 2002 · CEO Elon Musk

Space Exploration Technologies Corp., known as SpaceX, is an American aerospace manufacturer and space transport services company headquartered in Hawthorne, California. It was founded in 2002 by entrepreneur Elon Musk with the goal of reducing space transportation costs and enabling the colonization of Mars. SpaceX operates from many pads, on the East Coast of the US they operate from SLC-40 at Cape Canaveral Space Force Station and historic LC-39A at Kennedy Space Center. They also operate from SLC-4E at Vandenberg Space Force Base, California, usually for polar launches. Another launch site is being developed at Boca Chica, Texas.
