In Photos: The Advanced JPSS-1 Weather Satellite's Earth Mission

Understanding Earth's Weather

Ball Aerospace

The Joint Polar Satellite System-1 (JPSS-1), the first of an advanced new fleet of weather satellites, launched into space on Nov. 18, 2017 to begin its vital mission. See photos from the launch and preparations here in our mission gallery. Read our full launch story.

JPSS-1 will orbit the Earth, as seen in this illustration, gathering data to assist scientists in understanding Earth's weather, oceans and climate.

Dazzling Before Dawn

In addition to JPSS-1, the Delta II rocket also launched five small cubesats into orbit. They included one small satellite built to track Earth's weather, another to map satellite orbital decay and several other experimental payloads.

Penultimate Delta II Flight
