NASA and the U.S. Nationwide Oceanic and Atmospheric Administration (NOAA) are set to launch a brand new climate and local weather monitoring satellite tv for pc early Thursday (Nov. 10), and you’ll watch the motion stay.
The Joint Polar Satellite tv for pc System-2 (JPSS-2) spacecraft is scheduled to raise off Thursday from Vandenberg Area Pressure Base in California at 4:25 a.m. EST (0925 GMT; 1:25 a.m. native California time) atop a United Launch Alliance Atlas V rocket. Watch it right here at Area.com, courtesy of NASA, or immediately by way of the house company (opens in new tab); protection will start at 3:45 a.m. EST (0845 GMT).
The launch could also be seen from broad swaths of the California coast, climate allowing. So if you happen to stay within the Golden State and are an evening owl (or a really early riser), you may wish to go outdoors and lookup on the appointed time.

JPSS-2 will likely be operated by NOAA as soon as it reaches its closing vacation spot, a path in low Earth orbit that takes it over the planet’s poles. Two different JPSS spacecraft already examine Earth from that orbit, circling the globe 14 occasions each 24 hours and absolutely surveying the planet twice a day.
JPSS-2’s instrument suite will acquire knowledge about Earth’s floor temperatures, cloud densities and aerosols to be able to enhance weekly climate forecasts and extreme climate predictions, amongst different makes use of.
In a prelaunch press briefing held on Tuesday (Nov. 9), Jordan Gerth, meteorologist and satellite tv for pc scientist for NOAA’s Nationwide Climate Service, defined that JPSS-2’s contributions, whereas international in scope, even have very localized purposes.
“The observations are international. The predictions are native,” Gerth stated. “With JPSS, the standard of native three- to seven-day climate forecasts is excellent.”
Along with higher serving to you resolve whether or not or to not seize your umbrella earlier than heading out the door, JPSS-2 will even monitor sea ice, algae blooms, wildfires, ocean floor temperatures and temperatures in Earth’s ambiance to contribute knowledge to an archive of local weather analysis for international climate fashions.
JPSS-2 will launch atop an Atlas V 401, a bare-minimum variation of the workhorse rocket with a 13-foot-wide (4 meters) payload fairing, no stable rocket boosters and a single RL10-1 engine powering the car’s Centaur higher stage. This Atlas V additionally occurs to be the final to ever launch from Vandenberg Area Pressure Base.
“We’re launching the final Atlas V from the West Coast, enabling ULA to have some big functionality out of right here with their Vulcan car,” Capt. Zack Zounes, launch climate officer for the U.S. Area Pressure, stated throughout an Oct. 28 JPSS-2 briefing. (Vulcan is ULA’s next-generation rocket, which is scheduled to debut in 2023.)
Tucked beneath JPSS-2 contained in the Atlas V’s fairing is one other payload, NASA’s Low-Earth Orbit Flight Take a look at of an Inflatable Decelerator (LOFTID). LOFTID is a expertise demonstration of an expandable warmth protect designed to guard heavy payloads throughout atmospheric entries.
Punching a spacecraft by planetary atmospheres is without doubt one of the most troublesome feats to perform in spaceflight, and warmth shields are sometimes amongst a spacecraft’s heaviest elements. Inflatable warmth shields have the potential to enormously enhance the utmost payload mass NASA can land on Mars and different planets, company officers have stated. LOFTID’s flight will present essential knowledge about how such {hardware} performs within the harsh reentry atmosphere.
Joe Del Corso, LOFTID venture supervisor at NASA’s Langley Analysis Heart, defined LOFTID’s reentry process.
“After delivering JPSS-2 to Earth orbit, the Centaur second stage will deorbit the LOFTID car, flip the LOFTID car on, after which LOFTID will then inflate the aeroshell and be launched by the Centaur,” Del Corso stated throughout Tuesday’s media name.
Touring almost 29 occasions the velocity of sound, LOFTID’s reentry will likely be recorded by a number of onboard sensors, whose knowledge assortment will embrace “temperatures throughout the aeroshell, pressures and warmth flux on the nostril cap, in addition to 360-degree video on six video cameras, and IR knowledge from 12 infrared cameras,” Del Corso defined. LOFTID will ultimately splash down softly below parachutes, and groups hope to get better its payloads intact.
The JPSS-2 launch was initially scheduled for Nov. 1 however was delayed to permit launch groups to switch a battery on the Centaur.
