Established in 1958, the National Aeronautics and Space Administration (NASA) is an independent agency of the United States Federal Government that succeeded the National Advisory Committee for Aeronautics (NACA). It is responsible for the civilian space program, as well as aeronautics and aerospace research. Its vision is "To discover and expand knowledge for the benefit of humanity." Its core values are "safety, integrity, teamwork, excellence, and inclusion." NASA conducts research, develops technology and launches missions to explore and study Earth, the solar system, and the universe beyond. It also works to advance the state of knowledge in a wide range of scientific fields, including Earth and space science, planetary science, astrophysics, and heliophysics, and it collaborates with private companies and international partners to achieve its goals.

” data-gt-translate-attributes=”[{” attribute=””>NASA conducted a long-duration hot fire of an RS-25 certification engine on March 21, continuing a key series of testing to support future Space Launch System (SLS) missions to deep space as part of Artemis missions as the agency continues to inspire the world through discovery.

Operators fired the certification engine for 10 minutes (600 seconds), longer than the 500 seconds engines must fire during an actual mission, on the Fred Haise Test Stand at NASA’s Stennis Space Center near Bay St. Louis, Mississippi. Operators also fired the engine up to 113% power level, exceeding the 111% level needed during SLS launch. Hot fires of longer duration and higher power level allow operators to test the limits of engine performance and provide a margin of safety for flight operations. The March 21 hot fire was the fourth test in a series that began in early February to certify production of new RS-25 engines by lead contractor Aerojet Rocketdyne. The company is using advanced manufacturing techniques, such as 3D printing, to reduce the cost and time needed to build new engines for use on missions beginning with Artemis V. Four RS-25 engines help power SLS at launch, including on its Artemis missions to the Moon.

Artemis ile NASA, ilk kadın ve ilk beyaz olmayan insan da dahil olmak üzere insanları Ay’ı keşfetmek için Ay’a geri getirmek ve geleceğin temellerini atmak için tarihi bir göreve başlıyor. Mars seferler. Uzay Fırlatma Sistemi (SLS), Orion uzay aracını, astronotları ve temel malzemeleri tek bir kapsamlı görevde Ay’a taşıma kapasitesine sahip tek roket olarak duruyor.
