According to the National Weather Service, 85% of the data flowing into their weather forecast models come from polar-orbiting satellites like the one that will launch Tuesday.

The ATMS instrument is the second flight model and is slated to fly on the first JPSS satellite in 2016. "The Flight 2 development, build and test have proceeded smoothly and follow the success of the Flight 1 instrument for NPOESS Preparatory Project". "The rocket is in a safe condition, the spacecraft, JPSS-1, is in a safe condition". It was created to be the functional equivalent follow-on to the Advanced Microwave Sounder Units with improved sampling and coverage.

The weather satellite will have to wait at least 24 hours to begin its mission for the National Oceanic Atmospheric Administration (NOAA) and NASA after the attempted liftoff from Vandenberg Air Force Base in California today was postponed to November 15, according to the JPSS-1 live blog run by NASA.

Several instruments aboard the satellite will provide detailed observations of temperature, air moisture, ice, snow, fog, wildfires, precipitation and ozone around the world. Forecasters will be able to use the data to better predict weather events and hazards, such as a hurricane's track, and when a hurricane will intensify or weaken, as well as identifying power outages in addition to locating and evaluating damage following a storm. Once it's operational, it will be renamed NOAA-20.

Its launch, aboard a United Launch Alliance Delta II from Space Launch Complex-2W at Vandenberg Air Force Base, Calif., is set for 2:47 a.m. MST Tuesday.

It remained unclear when another attempt would occur, but mission managers were tentatively planning to try again for liftoff at 1:47 a.m. Wednesday.
