NASA launches advanced satellite to improve weather forecast

NASA on 18 November 2017 successfully launched a highly advanced polar-orbiting satellite to improve weather forecasts for the National Oceanic and Atmospheric Administration (NOAA). The satellite- Joint Polar Satellite System-1 (JPSS-1)-was launched through a United Launch Alliance Delta II rocket from Vandenberg Air Force Base in California, US.

Highlights:-
1. The solar arrays on JPSS-1 deployed approximately an hour after the launch and the spacecraft was operating on its own power.
2. The advanced technology will help improve weather forecasts up to seven days in advance.
3. It will become operation after a three-month checkout and validation of its five advanced instruments.
4. The satellite will be renamed NOAA-20 when it reaches its final orbit.
5. This is the first in a series of four such satellites in a collaborative programme between NOAA and NASA.
