NASA launching JPSS-1 weather satellite


Six instruments will collect information about the atmosphere, land, and oceans, measuring everything from temperature and moisture to ozone and vegetation.

The spacecraft was built by Ball Aerospace and involves a collaboration between NASA and the National Oceanic and Atmospheric Administration. Full coverage of the planet will be provided then twice a day. This satellite, which will be called NOAA-20 when it's in orbit, will observe more than just clouds.

The new satellite will also deliver critical observations during severe weather events like hurricanes, tornadoes and blizzards and is created to help improve forecasts three-to-seven days ahead of a severe weather event. "Using polar satellite data, we have been able to provide emergency managers with more accurate forecasts, allowing them to pre-position equipment and resources days before a storm". "JPSS will continue this trend", he added. Over longer timescales, this data will help improve our understanding of climate patterns that influence the weather, such as El Nino and La Nina. The mission is a joint effort between NOAA and NASA. - NASA, in partnership with the NOAA, scrubbed Tuesday's launch of a weather satellite that will help improve weather forecasts due to a last-minute technical problem.

The JPSS-1 spacecraft was built by Ball Aerospace in Boulder, Colo. Harris Corporation built the Cross-track Infrared Sounder.

NASA-TV will cover the launch live and can be viewed at, starting at 1:15 a.m. PST on November 10.

Ground crews at Vandenberg Air Force Base in California retracted a mobile gantry away from the Delta 2 rocket Monday afternoon, revealing the 128-foot-tall (39-meter) booster on its launch pad awaiting liftoff with a new polar-orbiting weather observatory.

NOAA-20 is expected to be in orbit for ten years.

Polar satellites like the JPSS-1, which orbit the globe from pole-to-pole 14 times a day, are considered the backbone of the global observing system.
