NASA's, NOAA's JPSS-1 Weather Satellite Launch Delayed After Rocket Issue

Posted November 15, 2017

The rocket is set to carry a small CubeSat - an advanced polar-orbiting environmental, or weather, satellite - into orbit as part of the Joint Polar Satellite System (JPSS-1) mission, a collaborative effort between NASA and the National Oceanic and Atmospheric Administration (NOAA).

The ATMS instrument is the second flight model and is slated to fly on the first JPSS satellite in 2016. The Launch Configuration Electromagnetic Interference (EMI) measures the electromagnetic emissions and subjects it to expected electromagnetic radiation that the satellite would experience at the launch site.

JPSS-1 is planned to be placed into a non-geosynchronous polar orbit that will allow for a almost complete coverage of the entire Earth's surfaces twice in each 24-hour period with state-of-the-art instruments that are expected to aid meteorologists and other scientists and researchers to better predict severe weather phenomena such as hurricanes up to seven days ahead of the incident. It was created to be the functional equivalent follow-on to the Advanced Microwave Sounder Units with improved sampling and coverage.

The National Weather Service anticipates being able to take advantage of these measurements to improve its forecasts, particularly for high-impact weather events, such as hurricanes and winter storms. JPSS will provide more detailed information about atmospheric temperature and air moisture leading to more accurate near-term weather predictions. NOAA funds and manages the program, operations and data products.

The launch of the Delta 2 rocket has been rescheduled for Wednesday, at 1:47 a.m. PST. NASA develops and builds the instruments, spacecraft and ground system and launches the satellites for NOAA.

Ball also built one of the five instruments on the spacecraft, the Ozone Mapping and Profiler Suite.

An aircraft forced a scrub of an Orbital ATK Antares 230 rocket at the Mid-Atlantic Regional Spaceport on November 11 with two boats drawing similar concerns during the second launch attempt 24 hours later. This interagency effort (JPSS) is the latest generation of USA polar-orbiting, non-geosynchronous environmental satellites.
