GILBERT, Ariz. (NOAA PR) — On July 26, in a clean room at the Northrop Grumman facility in Gilbert, Arizona, NOAA’s JPSS-2 satellite let out several loud pops as each of the five panels of its solar array detached from the body of the satellite and then unfolded, stretching out to its full 30-foot length. Under each panel, an engineer clad in a bunny suit flashed a thumbs up as latches clicked into place.

SILVER SPRING, Md. (NOAA PR) — NOAA’s JPSS-2 satellite has cleared a critical testing milestone, bringing it a step closer to launch. Last week, the polar-orbiting satellite emerged from the chamber after completing its thermal vacuum testing. This test is meant to show that the spacecraft and all of its instruments will perform successfully when exposed to the harsh environments of space. 

“I can absolutely say with 100% certainty that the observatory is working great,” said JPSS Flight Project Manager Andre Dress. “All the instruments are performing great, and we’re going to meet all our requirements – and then some.”

SILVER SPRING, Md. (NOAA PR) — NOAA and NASA are now targeting November 1, 2022 as the new launch date for NOAA’s Joint Polar Satellite System-2 (JPSS-2) mission. The launch was originally scheduled for September 30, 2022, however, the Visible Infrared Imaging Radiometer Suite instrument, or VIIRS, experienced a test equipment anomaly during thermal vacuum (TVAC) testing.

NASA will launch four Earth science missions in 2022 to provide scientists with more information about fundamental climate systems and processes including extreme storms, surface water and oceans, and atmospheric dust. Scientists will discuss the upcoming missions at the American Geophysical Union’s (AGU) 2021 Fall Meeting, hosted in New Orleans between Dec. 13 and 17.
