The JPSS-1 is the first in the National Oceanic and Atmospheric Administration's (NOAA) next-generation of four polar-orbiting satellites that provide the majority of data streamed into weather forecasting models.
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.
With JPSS-1, the threat of a "satellite gap" due to aging satellite fleet should be allayed.
JPSS-1 is the first in NOAA's series of four, next-generation operational environmental satellites created to circle the Earth in a polar orbit. 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. Instruments aboard polar-orbiting satellites, like ones aboard JPSS-1 and its preceding spacecraft, known as the Suomi-NPP, obtain data on the winds and moisture in the upper atmosphere.
The launch had to be delayed because a "bad reading on the first stage of satellite's United Launch Alliance Delta II rocket, as well as boats in the safety zone, forced NASA to call off the launch just minutes before liftoff", said a report by Space.com.
On April 11, 2017, at Vandenberg Air Force Base, a United Launch Alliance Delta II second stage is hoisted into the gantry at Space Launch Complex 2.
The launch will take place at 1:47 a.m. PST (4:47 a.m. EST) from Vandenberg Air Force Base in Santa Barbara County, California. "JPSS will continue this trend", he added. Originally planned as a research and risk-reduction mission in the JPSS series, NOAA has been using Suomi NPP as its primary operational satellite for global weather observations since May 2014.
The launch has been tentatively postponed 24 hours and is now set to liftoff at 1:47 a.m. Wednesday. This interagency effort (JPSS) is the latest generation of US polar-orbiting, non-geosynchronous environmental satellites.
