The Atlas V rocket’s West Coast work is completed.
United Launch Alliance’s (ULA) workhorse rocket lifted off in the present day (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.
The Atlas V rocket lifted off with a 24-minute delay on account of points with fueling, which compelled the bottom management workforce 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.
NASA is engaged on a possible telemetry concern as they haven’t confirmed if the satellite’s solar array deployed as anticipated. “Right now, the workforce has not but acquired information to substantiate solar array deployment. There will not be a problem, however we’re monitoring intently as extra telemetry information turns into obtainable,” NASA wrote (opens in new tab)after launch.”
JPSS-2, owned by the U.S. Nationwide Oceanic and Atmospheric Administration, will collect quite a lot of climate and local weather information as soon as it is up and operating. The second spacecraft, an inflatable warmth protect expertise demonstrator known as LOFTID, may assist NASA land super-heavy payloads on Mars down the highway.

The Atlas V flew in the present day within the rocket’s most stripped-down configuration, with none stable rocket boosters. JPSS-2 and LOFTID had been additionally housed in a 13-foot-wide (4 meters) payload fairing, the smallest obtainable for an Atlas V.
The rocket’s first-stage RD-180 engine burned for about 4 minutes earlier than a nominal foremost engine cutoff and first-stage separation, adopted by a sequence 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 services. Following in the present day’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 anticipated to debut someday within the first quarter of 2023.
Launching a climate powerhouse
At present’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 actually a climate satellite, however the relatively banal nomenclature would not do justice to the spacecraft’s capabilities. JPSS-2 is becoming a member of two different climate satellites in polar orbit and shall be an Earth-monitoring powerhouse.
The primary satellite within the JPSS program, the Suomi-NPP spacecraft, launched in 2011. The second, NOAA-20, adopted go well with in 2017. (NOAA-20 was referred to as JPSS-1 till it reached its last orbit.) JPSS-2 is becoming a member of them to assist scientists gather, and higher perceive, monumental quantities of meteorological information that may enhance world 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 Individuals,” Jordan Gerth, a meteorologist and satellite scientist for NOAA’s Nationwide Climate Service, stated throughout a prelaunch press briefing on Tuesday night (Nov. 8). “First, JPSS information is a serious enter into U.S. and worldwide world numerical climate prediction modeling techniques.”
Gerth used a tropical storm as a hypothetical instance to clarify what sort of information JPSS-2’s scientific devices will collect.
“The Seen Infrared Imaging Radiometer Suite, or VIIRS instrument, gives imagery at a spatial decision of 375 meters, or roughly 1 / 4 mile, and allows the detection of thunderstorm options equivalent to overshooting tops,” Gerth stated. Overshooting tops, he defined, may also help decide the severity of a storm. VIIRS may also detect mesospheric gravity waves emanating from the middle of tropical techniques.
JPSS-2 can be carrying the Superior Know-how Microwave Sounder (ATMS), which might see via 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 whole planet twice day by day. Along with its climate work, the satellite, which shall 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 least seven years. The opposite payload that went up on the Atlas V in the present day, LOFTID (quick for “Low-Earth Orbit Flight Take a look at of an Inflatable Decelerator”), will not function for practically that lengthy.
LOFTID relies on hypersonic inflatable aerodynamic decelerator (HIAD) expertise. It is going to take a look at the capabilities and efficiency of an expandable warmth protect throughout reentry via 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 presently attainable. The company will want such heavy-duty touchdown tech to construct a analysis outpost on the Pink Planet, which it hopes to start out doing within the late 2030s or early 2040s.
LOFTID is filled with sensors, which is able to assist mission workforce members characterize the automobile’s fiery return to Earth. LOFTID is anticipated to succeed in a most velocity of practically 18,000 mph (30,000 kph) throughout that descent, which is able to 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 line with plan.
“Throughout entry,” Joe Del Corso, LOFTID venture supervisor at NASA’s Langley Analysis Heart in Virginia, stated throughout Tuesday’s briefing, “LOFTID may even be taking various 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 of get an aerial mapping of temperature from the fiber optics pressure sensor, or FOSS, which shall be on the nostril of the automobile.”
LOFTID may even eject a further information core throughout its fall to Earth, so workforce members could have entry to this info even when the primary automobile is broken or destroyed.
Although no extra Atlas V autos will launch from Vandenberg, the rocket is not prepared for retirement but. There are nonetheless a number of Atlas V missions left on ULA’s books, however all of them will fly from Florida’s Area Coast.
