ULA Delta II JPSS-1 Scrub Statement

Boulder's Ball Aerospace, NOAA primed for polar-orbiting satellite launch has been seven years in the planning

The most important weather satellite you've never heard of launches to space Tuesday

The Joint Polar Satellite System-1, or JPPS-1, was designed and built by Boulder's Ball Aerospace, and once it enters polar orbit, it will be known as NOAA-20, feeding National Weather Service models for Boulder's National Oceanic and Atmospheric Administration. JPSS will provide more detailed information about atmospheric temperature and air moisture leading to more accurate near-term weather predictions.

Northrop Grumman Corporation (NYSE:NOC) will build and deliver the Advanced Technology Microwave Sounder (ATMS) for the Joint Polar Satellite Systems (JPSS) under a contract with NASA. Over longer timescales, this data will help improve our understanding of climate patterns that influence the weather, such as El Nino and La Nina.

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.

The launch of a United Launch Alliance Delta II carrying the JPSS-1 mission for NASA and NOAA was scrubbed today due to a red range and a late launch vehicle alarm. "We are proud to contribute to NOAA's continued leadership in critical weather forecasting throughout the entire JPSS series". JPSS 1 will go into orbit around 500 miles (800 kilometers) high and use five instruments to measure temperature and humidity in the atmosphere, solar radiation reflected off the Earth, ozone health, and other key data to aid weather forecasters.

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. The next launch attempt will be on Wednesday (Nov. 15) at 4:47 a.m. EST. "The Flight 2 development, build and test have proceeded smoothly and follow the success of the Flight 1 instrument for NPOESS Preparatory Project".

Liftoff of the United Launch Alliance booster aimed for 1:47 a.m. from Space Launch Complex-2.

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.

Assuming that JPSS-1 launches successfully on Tuesday and functions normally in orbit, the USA will again have two working polar satellites at work at the same time.
