NASA successfully launches NOAA's JPSS-1 satellite to improve weather prediction on a Delta II rocket

**NASA** on Saturday successfully launched for the National Oceanic and Atmospheric Administration (NOAA) a highly advanced polar-orbiting satellite to improve weather forecasts up to seven days in advance. The Joint Polar Satellite System-1 (JPSS-1) lifted off on a United Launch Alliance Delta II rocket from Vandenberg Air Force Base, California, NASA said.

This is the first in a series of four such satellites in a collaborative programme between NOAA and NASA. Approximately an hour after launch, the solar arrays on JPSS-1 deployed and the spacecraft was operating on its own power. JPSS-1 will be renamed NOAA-20 when it reaches its final orbit. Following a three-month checkout and validation of its five advanced instruments, the satellite will become operational, NASA said. The satellite will improve weather forecasting, such as predicting a hurricane’s track, and will help agencies involved with post-storm recovery by visualizing storm damage and the geographic extent of power outages. JPSS-1 data will also improve recognition of climate patterns that influence the weather, such as El Nino and La Nina, according to NASA.
