ULA Delta II JPSS-1 Scrub Statement

This illustration depicts the Joint Polar Satellite System-1, or JPSS-1, spacecraft created to provide forecasters with crucial environmental science data to provide a better understanding of changes in the Earth's weather, oceans, and climate.

ATMS will provide critical microwave data, including atmospheric temperature and moisture profiles, to support weather forecasting for the operational JPSS system.

Ball Aerospace designed and built the JPSS-1 satellite bus, and Ozone Mapping and Profiler Suite instrument, integrated all five of the spacecraft's instruments and performed satellite-level testing and launch support. 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. "The JPSS satellite system will provide advanced forecasting on not only hurricanes, but also risky weather events threatening communities across the United States".

With JPSS-1, the threat of a "satellite gap" due to aging satellite fleet should be allayed.

The ATMS instrument is the second flight model and is slated to fly on the first JPSS satellite in 2016.

The ATMS is the next generation of cross-track sounders that will provide a wealth of data and global observational information of the Earth's surface and atmosphere using microwaves.




Satellites like JPSS-1 are not responsible for the images typically shown on your nightly weather forecast or your phone's weather app, since most weather imagery comes from geostationary satellites, which orbit above a fixed point on the planet. NASA develops and builds the instruments, spacecraft and ground system and launches the satellites for NOAA.

NASA launch manager Omar Baez confirmed that up until 4 minutes before liftoff, the only issue launch controllers were tracking were a few boats in the boat exclusion area off the coast near Vandenberg Air Force Base, but then one parameter on the first stage also went out of limits.

Cloud properties can be determined using simultaneous data collection and measurements from other instruments such as VIIRS to gain a better understanding of the role that clouds play in the energy cycle as well as in global climate change.

The JPSS-1 satellite is scheduled to launch on November 10 at 1:47 a.m. PST from Vandenberg Air Force Base, Calif.

Fitted with nine strap-on solid rocket boosters made by Orbital ATK and a first stage RS-27A engine and second stage AJ10-118K engine, both from Aerojet Rocketdyne, the Delta 2 rocket is poised for its 154th mission Tuesday.

The satellite, which measures 14.8 feet (4.5 meters) long and weighs 5,060 pounds (2,295 kilograms), won't be alone. One more Delta 2 launch is planned in late 2018 before ULA retires the workhorse rocket.
