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

A United Launch Alliance live tweet said that the Delta II rocket had just a 66-second window to launch JPSS-1 into the correct orbit.

NASA is preparing to launch the Joint Polar Satellite System-1, or JPSS-1, satellite on behalf of the National Oceanic and Atmospheric Administration (NOAA) to provide essential data for timely and accurate weather forecasts and for tracking environmental events such as forest fires and droughts. "This transition of the second flight unit to the Joint Polar Satellite Systems not only capitalizes fully on that previous experience, but also demonstrates our commitment to developing a long-term partnership with both NASA and NOAA on this program".

A United Launch Alliance Delta II rocket carrying the Joint Polar Satellite System 1 weather satellite stands atop its launchpad at Vandenberg Air Force Base in California after a rocket issue prevented a planned liftoff on November 14, 2017. 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.

A press release from Vandenberg Air Force Base says the planned launch was scrubbed early Tuesday because of an unspecified issue and managers didn't have enough time to resolve it.

On July 12, 2016, the first stage of the ULA Delta II rocket was transported to SLC-2 at Vandenberg and positioned on the launch pad.

Officials have postponed the California launch of a new type of US weather satellite meant to improve the accuracy of extended forecasts. "JPSS will continue this trend", he added.

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. Shortly after the postponement was revealed, Omar Baez Jr., a NASA senior launch director, confirmed that the plan was to retry the launch again at 1:47 a.m. Wednesday. 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 US the benefit of two, sophisticated polar satellites in the same orbit.
