NOAA's next-generation weather satellite JPSS-1 set to launch Tuesday

14 November 2017

The first Joint Polar Satellite System, is set to launch at 1:47 a.m.

The booster will carry the first in a series of four satellites for the Joint Polar Satellite System, JPSS-1.

In its orbit, the satellite will pass over the equator about 14 times per day, and cover the globe twice every 24 hours. JPSS-1 will help forecasters create more precise forecasts up to seven days in advance.

It will be known as NOAA-20 when it reaches orbit at 512 miles above the Earth, and it will replace the Soumi-NPP, which was a prototype test bed, becoming the primary USA polar-orbiting satellite.

This information supplements the data gathered from weather balloons launched at sites across the US, particularly for large expanses of water where balloon launches are not feasible. Both the ULA Delta- II rocket and the JPSS-1 satellite were in a safe condition after the attempt the Space.com report added. This technology, which is also on Suomi NPP, aided in weather information gathering after Hurricane Maria devastated Puerto Rico in September 2017.

For years, policy makers and scientists anxious about a looming polar-orbiting satellite gap that could come once one satellite blinked out from old age, prior to the next one launching. JPSS-1, which will be known as NOAA-20 when it reaches orbit, will join Suomi NPP, the joint NOAA-NASA weather satellite, giving the USA the benefit of two, sophisticated polar satellites in the same orbit. This would avoid a dreaded gap that could have adversely affected weather forecast accuracy in the U.S.

"We're pretty excited about the launch", said Joe Pica, director of the weather service's office of operations, who added the spacecraft is created to last about seven years.

The satellite will have the ability to provide scientists, researchers, and meteorologists with the data necessary to predict severe weather up to seven days ahead of time.

The JPSS will provide more data, and this data will be fed into the prediction models. Harris Corporation built the Cross-track Infrared Sounder.

After billions of dollars in cost overruns and delays, NASA is planning to launch one of the most important weather satellites ever early Tuesday morning.

Another satellite overhead means more information for the models in-hand.

The five next-generation instruments on JPSS will be a major upgrade from NOAA's legacy polar-orbiting satellites.
