First-of-Its-Kind Satellite Launches to Track Earth's Weather Like Never Before #FACTS NOV. 18, 2017. The first in a series of four advanced polar-orbiting #satelliteslaunched to space on its third try early Saturday (Nov. 18), turning its watchful eye to improving the accuracy of #weather forecasts and Earth observations.
The new Joint Polar Satellite System-1 satellite, or JPSS-1, launched into orbit atop a United Launch Alliance-built #deltaII #rocket at 4:47 a.m. EST (0947 GMT), lighting up the predawn #sky over its Vandenberg #AirForce Base in California. The successful liftoff came after two scrubbed #launch attempts earlier this week due to high winds and boats inside the launch range restriction zone offshore. "Things went absolutely perfect today," #NASA launch manager #omarbaezsaid after the JPSS-1 launch. "The nation's got another wonderful weather asset up in #spaceX
The National Oceanic and Atmospheric Administration, in partnership with NASA, operates both #geostationary satellites, like GOES-16, which stay in a fixed spot over Earth as they orbit, as well as polar-orbiting satellites, like Suomi NPP, which launched in 2011. Suomi NPP was originally intended to test the technology in store for JPSS-1, officials said at a news conference Sunday (Nov. 12), but it has become a valuable #weather and Earth analysis satellite. "This is huge," #gregmandtdirector of the #jpssprogram, said during live commentary just after the dazzling liftoff of JPSS-1. "JPSS 1 is part of a national polar #orbiting weather satellite program, and we really need this because 85 percent of all the date from our weather forecast models come from this series of weather satellite. We're looking forward to getting good data from this #satellite
JPSS-1 will follow in #suomiNPP's path — literally — by chasing its precursor around in the same polar #orbitboasting "instruments so precise that they can measure the temperature to better than a tenth of a degree from the surface of the #Earth all the way to the edge of space," Mandt said during the Nov. 12 news conference. The #spacecraft will pass around the globe every 90 minutes. #ninfonetwork #VEHICLENINFO #foodninfo
