NASA launching JPSS-1 weather satellite

JPSS-1 Launch Targeted For 4:47 AM EST on Tuesday, Nov. 14 From Vandenberg Air Force Base

Boulder's Ball Aerospace, NOAA primed for polar-orbiting satellite launch has been seven years in the planning

"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".

Crews have postponed this morning's expected launch of a rocket that would have carried Idaho's first satellite into space.

While a geostationary satellite stays in one spot and frequently sends forecasters a picture of what's happening on earth, a polar satellite, like JPSS-1, zooms around and sends more detailed snapshots, just twice a day.

This next-generation weather satellite - known as Joint Polar Satellite System-1 - promises "a leap in data collection and quality equivalent to going from an old flip-phone to an iPhone X", said meteorologist Ryan Maue of, a meteorological firm.

The Joint Polar Satellite System-1, or JPSS-1, spacecraft is checked out on October 8, 2015, at Ball Aerospace in Boulder, Colorado.

A scheduled early morning launch of a rocket from Vandenberg Air Force Base was a no-go.

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

The new satellite will be the most advanced polar-orbiting weather platform the US has yet put to use, NOAA officials said, since it will carry upgraded instruments able to gather more weather information than ever before.

The JPSS-1 satellite is scheduled to launch on November 10 at 1:47 a.m. PST from Vandenberg Air Force Base, Calif. "JPSS will continue this trend". "For the better part of a decade, scientists and policymakers have been very concerned about a gap in polar-orbiting satellite coverage of the Earth due to delays in launching JPSS-1 and the obvious aging or potential failure of older birds in orbit", according to Maue.

Northrop Grumman Corporation (NYSE:NOC) will build and deliver the Advanced Technology Microwave Sounder (ATMS) for the Joint Polar Satellite Systems (JPSS) under a contract with NASA.

It remained unclear when another attempt would occur, but mission managers were tentatively planning to try again for liftoff at 1:47 a.m. Wednesday.

Polar satellites like the JPSS-1, which orbit the globe from pole-to-pole 14 times a day, are considered the backbone of the global observing system.
