NASA, European Space Agency go for Jupiter's moons

In June, NOAA's GOES-U, the Geostationary Operational Environmental Satellites-U, was launched aboard a SpaceX Falcon Heavy rocket. The fourth of four GOES-R series weather and environment monitoring satellites, GOES-U will monitor the Western Hemisphere, including the Americas, the Caribbean and the Atlantic Ocean to western Africa. After a fortnight's transfer from delivery into geostationary transfer orbit, GOES-U was inserted into its checkout slot, about 35,700 kilometers altitude, and renamed GOES-19. Following an extended instrument checkout period that began in August, GOES-19 is to drift from checkout to its operational slot in 2025 to commence environmental monitoring with the rest of the GOES-R satellites
