Before its flight demonstration in fall 2022, an inflatable heat shield technology that could one day land humans on Mars was put through its paces at multiple NASA facilities.
NASA's Low-Earth Orbit Flight Test of an Inflatable Decelerator (LOFTID) is currently at Vandenberg Space Force Base in California, where teams are preparing the novel technology for launch as a secondary payload with the National Oceanic and Atmospheric Administration's (NOAA) Joint Polar Satellite System-2 (JPSS-2) satellite, which will help track and predict Earth's weather and climate.
After hitching a ride to space aboard a United Launch Alliance (ULA) Atlas V rocket, LOFTID (https://www.nasa.gov/loftid) will complete a controlled inflation of its heat shield and then re-enter the atmosphere at a velocity of 18,000 miles per hour (8 kilometers per second). Designed to withstand temperatures as high as 2900°F (1600°C), this first-ever in-orbit test of this technology will prove if it can successfully slow down large payloads – such as crewed spacecraft, robotic explorers, and rocket components – enabling them to survive the heat of re-entry.

Prior to shipping across the country from NASA's Langley Research Center in Hampton, Virginia,  LOFTID's journey to launch began with a series of environmental tests and preparation activities to ensure that the aeroshell will be able to withstand the harsh conditions of launch and space.
Earlier in 2022, the LOFTID team successfully performed a match-mate test, which verifies that all the hardware from both NASA and ULA will fit together and align properly. This also served as a rehearsal for the final integration procedures occurring at the launch site.
After completing the match-mate testing, LOFTID went through electromagnetic compatibility testing. This test ensured the spacecraft does not emit radio frequencies that could interfere with anything on the integrated launch vehicle. This test also checked that LOFTID won't be harmed by any of the electromagnetic radiation it may experience leading up to and during launch and throughout its mission.
Following electromagnetic compatibility testing, the team performed a complete system test. This end-to-end ground test of the LOFTID re-entry vehicle was conducted inside a 60-foot vacuum sphere that can simulate a space-like environment. The re-entry vehicle is composed of several segments that link the inflatable structure to the inflation system, avionics, ejectable data recorder, and parachute system. A full test of the flight sequence was run in vacuum, exactly as it will execute during the flight demonstration, including deployment and inflation of the aeroshell.

Once fully inflated, the inflatable heatshield, or aeroshell, was inspected and laser-scanned to ensure exact measurements before being repacked into its stowed configuration for flight.
With the inflatable aeroshell repacked, its weight and center of gravity were measured. . Determining these characteristics is important to ensure the spacecraft will perform as expected during flight.
With LOFTID in its launch configuration, LOFTID was shipped in July from Langley to NASA's Goddard Space Flight Center, in Greenbelt, Maryland, for acceptance vibration testing. Vibration testing is performed to ensure that LOFTID will not be damaged during the intense launch and re-entry process.
Following these tests, LOFTID was returned to Langley, where it underwent one final test to ensure it was fully functional before being packed and shipped to its final destination, Vandenberg Space Force Base, on the central coast of California in Santa Barbara County.

The LOFTID and payload adapter have been integrated. The stacked components were cleaned and transported to the Payload Processing Facility for encapsulation with the JPSS-2 payload. Once everything is packed into the payload fairing of the ULA Atlas V, the rocket will be rolled out to the launch pad for launch.
LOFTID is dedicated to the memory of Bernard Kutter, manager of advanced programs at ULA, who passed away in August 2020 and was an advocate for technologies like LOFTID that can lower the cost of space access.
The LOFTID project is managed and funded through NASA's Technology Demonstration Missions program, part of the agency's Space Technology Mission Directorate. The project is led by NASA's Langley Research Center in Hampton, Virginia, in partnership with United Launch Alliance and with contributions from NASA's Ames Research Center in Silicon Valley, Marshall Space Flight Center in Huntsville, Alabama, and Armstrong Flight Research Center in Edwards, California. NASA's Launch Services Program, based at the agency's Kennedy Space Center in Florida, is responsible for managing the launch service.

Technicians and engineers encapsulated the National Oceanic and Atmospheric Administration's (NOAA) Joint Polar Satellite System-2 (JPSS-2) satellite within a protective payload fairing inside the Astrotech Space Operations facility at Vandenberg Space Force Base in California, on Monday, Oct. 12.
Prior to placement inside the 4-meter-wide United Launch Alliance (ULA) fairing, teams stacked JPSS-2 onto a payload adapter canister containing the re-entry vehicle for NASA's secondary payload, known as Low-Earth Orbit Flight Test of an Inflatable Decelerator, or LOFTID. The encapsulated satellite will be transported to Vandenberg's Space Launch Complex-3 and hoisted by crane atop the second stage of a ULA Atlas V 401 rocket for launch Nov. 1 at 2:25 a.m. PDT.
At launch, JPSS-2 weighs 5,567 pounds and has four highly sophisticated instruments to measure weather and climate conditions on Earth:

• The Advanced Technology Microwave Sounder (ATMS) sees through clouds like an X-ray and can view the structure of the atmosphere underneath those clouds and inside of storms.
• The Visible Infrared Imaging Radiometer Suite (VIIRS) measures in the infrared and visible part of the spectrum and can image hurricanes, floods, dust storms, cloud patterns, ocean color, and help locate and map wildfires.
• The Cross-track Infrared Sounder (CrIS) works together with ATMS to take detailed measurements of the atmospheric conditions needed to generate extreme weather forecasts days in advance.
• The Ozone Mapping and Profiler Suite (OMPS) consists of sensors to track the concentration of ozone in the atmosphere and measure sulfur dioxide and other aerosols emitted from volcanoes and particulates from wildfires.

Спойлер

As JPSS-2 makes its way to a polar Earth orbit, LOFTID will re-enter the atmosphere as it descends back to Earth and will land in the Pacific Ocean just over two hours after launch. LOFTID will demonstrate how the inflatable aeroshell, or heat shield, can slow down and survive re-entry in conditions relevant to many potential applications, whether landing humans on Mars, new missions to Venus and Titan, or returning heavier payloads and samples from low-Earth orbit.
LOFTID is a partnership with ULA. NASA's LOFTID project is managed and funded through NASA's Technology Demonstration Missions program, part of the agency's Space Technology Mission Directorate.  LOFTID is led by Langley Research Center in Hampton, Virginia, with contributions from Ames Research Center in Silicon Valley, Marshall Space Flight Center in Huntsville, Alabama, Armstrong Flight Research Center in Edwards, California, and multiple U.S. small businesses that contributed to the hardware. NASA's Launch Services Program, based at Kennedy Space Center in Florida, manages the launch service.

ЦитироватьСША вывели на орбиту метеоспутник с помощью оснащенной российским двигателем ракеты
НЬЮ-ЙОРК, 10 ноября. /ТАСС/. США вывели в четверг в космос очередной - уже второй - метеорологический спутник нового поколения JPSS с помощью ракеты-носителя "Атлас-5", первая ступень которой оснащена российским двигателем РД-180. Как отметило на своем сайте Национальное управление США по аэронавтике и исследованию космического пространства (NASA), аппарат массой 2,5 тонны будет находиться на полярной орбите, совершая в сутки 14 витков вокруг Земли на высоте 824 км.

Запуск был осуществлен с базы Космических сил США Ванденберг (штат Калифорния) в _{12:53 мск}. Эксплуатацией аппарата будет заниматься Национальное управление по исследованию океанов и атмосферы, которое структурно функционирует при Министерстве торговли США.

JPSS предназначен для дистанционного зондирования Земли, а также наблюдений за Мировым океаном и атмосферой. Первый такой аппарат был запущен в ноябре 2017 года. Всего предполагается вывести на полярную орбиту пять JPSS. Срок эксплуатации каждого должен составить семь лет.

Американские специалисты рассчитывают, что с помощью научных приборов, установленных на этих спутниках, удастся существенно повысить точность прогнозов погоды.

Спойлер

Кислородно-керосиновый РД-180 разработан НПО "Энергомаш" (входит в Роскосмос). Он используется в США с 2000 года. 3 марта занимавший тогда должность главы Роскосмоса Дмитрий Рогозин сообщил в интервью телеканалу "Россия 24" о принятом решении в связи с санкционной политикой Запада прекратить все поставки в США ракетных двигателей НПО "Энергомаш", а также об отказе проводить техническое обслуживание оставшихся у американской стороны неиспользованных РД-180 для "Атласа-5" и РД-181 для носителя "Антарес".

После развертывания в космосе, НАСА визуально подтвердило в прямом эфире полное надувание LOFTID на высоте около 78 миль (125 км), что ознаменовало начало повторного входа в атмосферу. Телеметрия была ненадолго потеряна, когда демонстратор возвращался на Землю, но в итоге все обошлось.
Надувная конструкция приводнилась всего в 5 милях (8 км) от спасательного судна Kahana II, что позволило легко извлечь его, и LOFTID сбросил свой бортовой самописец, как и планировалось, для сбора данных.
LOFTID стоимостью 93 миллиона долларов, запущенный вместе с Объединенной полярной спутниковой системой-2 (JPSS-2), представляет собой надуваемую аэродинамическую оболочку, предназначенную для замедления входа космического корабля в марсианское небо и уменьшения количества тепла, создаваемого атмосферным трением. НАСА заявляет, что эта технология представляет собой одно из решений для посадки в сверхтонкой марсианской атмосфере , что делает посадку особенно деликатной, поскольку космический корабль сталкивается с лишь небольшой силой сопротивления по сравнению с земной атмосферой.
