The Atlas V rocket’s West Coast work is completed.
United Launch Alliance’s (ULA) workhorse rocket lifted off right this moment (Nov. 10) from California’s Vandenberg Space Force Base at 4:49 a.m. EST (0949 GMT; 1:49 a.m. native California time), carrying two payloads towards Earth orbit.Â
The Atlas V rocket lifted off with a 24-minute delay as a consequence of points with fueling, which pressured the bottom management group to briefly halt the countdown. After liftoff, the Joint Polar Satellite System-2 (JPSS-2), separated flawlessly from the rocket’s Centaur higher stage about 28 minutes into the flight.Â
NASA is engaged on a possible telemetry concern as they haven’t confirmed if the satellite’s solar array deployed as anticipated. “Presently, the group has not but obtained information to verify solar array deployment. There might not be a problem, however we’re monitoring intently as extra telemetry information turns into accessible,” NASA wrote (opens in new tab)after launch.”
JPSS-2, owned by the U.S. Nationwide Oceanic and Atmospheric Administration, will collect a wide range of climate and local weather information as soon as it is up and working. The second spacecraft, an inflatable warmth defend know-how demonstrator known as LOFTID, may assist NASA land super-heavy payloads on Mars down the highway.Â

The Atlas V flew right this moment within the rocket’s most stripped-down configuration, with none stable rocket boosters. JPSS-2 and LOFTID have been additionally housed in a 13-foot-wide (4 meters) payload fairing, the smallest accessible for an Atlas V.
The rocket’s first-stage RD-180 engine burned for about 4 minutes earlier than a nominal primary engine cutoff and first-stage separation, adopted by a collection of burns from the Atlas V’s Centaur higher stage to maintain carrying the 2 payloads aloft. JPSS-2 was deployed about 28 minutes after liftoff right into a polar orbit 440 miles (710 kilometers) above Earth. LOFTID is scheduled to deploy right into a extremely elliptical orbit at T+75 minutes, then head again down for a fiery reentry trial in Earth’s atmosphere.
That this was the final Atlas V launch from the West Coast symbolizes a shift forward for ULA’s California launch amenities. Following right this moment’s mission, Vandenberg’s Area Launch Complicated 3-East will start upgrades to facilitate launches of the corporate’s new Vulcan Centaur rocket, which is predicted to debut someday within the first quarter of 2023.Â
Launching a climate powerhouse
As we speak’s mission additionally represents a shift ahead for each payloads’ respective applied sciences. JPSS-2 — a joint effort of NASA and the U.S. Nationwide Oceanic and Atmospheric Administration (NOAA) — is basically a climate satellite, however the fairly banal nomenclature does not do justice to the spacecraft’s capabilities. JPSS-2 is becoming a member of two different climate satellites in polar orbit and will probably be an Earth-monitoring powerhouse.Â
The primary satellite within the JPSS program, the Suomi-NPP spacecraft, launched in 2011. The second, NOAA-20, adopted swimsuit in 2017. (NOAA-20 was referred to as JPSS-1 till it reached its remaining orbit.) JPSS-2 is becoming a member of them to assist scientists accumulate, and higher perceive, monumental quantities of meteorological information that may enhance international climate fashions, amongst different makes use of.
“NOAA 20, Suomi-NPP, and shortly JPSS-2 support our meteorologists in assembly the Nationwide Climate Service mission for all People,” Jordan Gerth, a meteorologist and satellite scientist for NOAA’s Nationwide Climate Service, mentioned throughout a prelaunch press briefing on Tuesday night (Nov. 8). “First, JPSS information is a significant enter into U.S. and worldwide international numerical climate prediction modeling programs.”
Gerth used a tropical storm as a hypothetical instance to clarify what sort of information JPSS-2’s scientific devices will collect.Â
“The Seen Infrared Imaging Radiometer Suite, or VIIRS instrument, supplies imagery at a spatial decision of 375 meters, or roughly 1 / 4 mile, and allows the detection of thunderstorm options corresponding to overshooting tops,” Gerth mentioned. Overshooting tops, he defined, may help decide the severity of a storm. VIIRS can even detect mesospheric gravity waves emanating from the middle of tropical programs.Â
JPSS-2 can also be carrying the Superior Know-how Microwave Sounder (ATMS), which may see by means of cloud canopies to find out the inside constructions of hurricane eye partitions. The Cross-track Infrared Sounder (CrIS) aboard the spacecraft will work in tandem with ATMS to transform temperature and moisture information at completely different elevations into 3D representations for atmospheric fashions.
In its polar orbit, JPSS-2 will circle the globe 14 instances each 24 hours, offering full protection of the complete planet twice each day. Along with its climate work, the satellite, which will probably be operated by NOAA, is designed to watch sea ice, ocean shade, temperature, and biodiversity shifts, in addition to wildfires, floods and even financial restoration efforts in areas affected by pure disasters.

Testing heavy-duty Mars touchdown tech
JPSS-2 is designed to assemble information from orbit for at the very least seven years. The opposite payload that went up on the Atlas V right this moment, LOFTID (quick for “Low-Earth Orbit Flight Take a look at of an Inflatable Decelerator”), will not function for practically that lengthy.
LOFTID is predicated on hypersonic inflatable aerodynamic decelerator (HIAD) know-how. It can take a look at the capabilities and efficiency of an expandable warmth defend throughout reentry by means of a planetary ambiance. Expandable warmth shields have excessive potential advantages for the way forward for spaceflight, NASA officers say, probably permitting a lot heavier payloads to be landed safely on the floor of Mars than is at the moment attainable. The company will want such heavy-duty touchdown tech to construct a analysis outpost on the Purple Planet, which it hopes to begin doing within the late 2030s or early 2040s.
LOFTID is full of sensors, which can assist mission group members characterize the automobile’s fiery return to Earth. LOFTID is predicted to succeed in a most pace of practically 18,000 mph (30,000 kph) throughout that descent, which can finish with a parachute-aided splashdown a number of hundred miles off the coast of Hawaii about 110 minutes after liftoff, if all goes in response to plan.
“Throughout entry,” Joe Del Corso, LOFTID venture supervisor at NASA’s Langley Analysis Heart in Virginia, mentioned throughout Tuesday’s briefing, “LOFTID may also be taking plenty of measurements throughout a collection of devices, together with temperatures throughout the aeroshell, pressures and warmth flux on the nostril cap, in addition to 360-degree video on six video cameras, and IR information from 12 infrared cameras. We’ll additionally be capable to get an aerial mapping of temperature from the fiber optics pressure sensor, or FOSS, which will probably be on the nostril of the automobile.”Â
LOFTID may also eject an extra information core throughout its fall to Earth, so group members could have entry to this data even when the principle automobile is broken or destroyed.
Although no extra Atlas V automobiles will launch from Vandenberg, the rocket is not prepared for retirement but. There are nonetheless quite a lot of Atlas V missions left on ULA’s books, however all of them will fly from Florida’s Area Coast.
