NASA’s successfully tests RS-25 Rocket Engines

 

NASA - National Aeronautics and Space AdministrationWashington, D.C. – The largest rocket element NASA has ever built, the core stage of NASA’s Space Launch System (SLS) rocket, fired its four RS-25 engines for 8 minutes and 19 seconds Thursday at NASA’s Stennis Space Center near Bay St. Louis, Mississippi.

The successful test, known as a hot fire, is a critical milestone ahead of the agency’s Artemis I mission, which will send an uncrewed Orion spacecraft on a test flight around the Moon and back to Earth, paving the way for future Artemis missions with astronauts.

NASA Lunar Gateway’s Core Flight Software to be created by Goddard Space Flight Center

 

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – NASA is improving a flight software system to help create and certify essential software for the lunar Gateway.

As part of the Artemis program, NASA will send astronauts to the Moon and establish a sustained lunar presence by the end of the decade. The Gateway will provide a waypoint for lunar exploration and allow astronauts to live and work in lunar orbit as well as host science instruments and experiments.

NASA Conducts SLS Rocket Core Stage Test for Artemis I Moon Mission

 

NASA - National Aeronautics and Space AdministrationWashington, D.C. – NASA conducted a hot fire Saturday of the core stage for the agency’s Space Launch System (SLS) rocket that will launch the Artemis I mission to the Moon. The hot fire is the final test of the Green Run series.

The test plan called for the rocket’s four RS-25 engines to fire for a little more than eight minutes – the same amount of time it will take to send the rocket to space following launch. The team successfully completed the countdown and ignited the engines, but the engines shut down a little more than one minute into the hot fire.

NASA to proceed with Green Run Hot Fire of Space Launch System Rocket

 

NASA - National Aeronautics and Space AdministrationHuntsville, AL – NASA is targeting the final test in the Green Run series, the hot fire, for as early as January 17th, 2021. The hot fire is the culmination of the Green Run test series, an eight-part test campaign that gradually brings the core stage of the Space Launch System (SLS) — the deep-space rocket that will power the agency’s next-generation human Moon missions — to life for the first time.

NASA conducted the seventh test of the SLS core stage Green Run test series – the wet dress rehearsal – on December 20th at NASA’s Stennis Space Center near Bay St. Louis, Mississippi, and marked the first time cryogenic, or super cold, liquid propellant was fully loaded into, and drained from, the SLS core stage’s two immense tanks.

Fully loading the propellant and detecting no leaks is a major milestone for the Green Run test series. A total of 114 tanker trucks delivered propellant to six propellant barges next to the B-2 Test Stand at NASA’s Stennis Space Center near Bay St. Louis, Mississippi. The barges deliver more than 733,000 gallons of liquid hydrogen and liquid oxygen to the core stage for NASA’s Space Launch System (SLS) rocket as part of the seventh test in the Green Run test series.

NASA Building Core Stages for Second, Third Artemis Flights

 

NASA - National Aeronautics and Space AdministrationWashington, D.C. – Technicians are simultaneously manufacturing NASA’s Space Launch System (SLS) core stages for the Artemis II and Artemis III lunar missions at NASA’s Michoud Assembly Facility in New Orleans.

The core stage for the deep space rocket consists of two huge propellant tanks, four RS-25 engines, and miles of cabling for the avionics systems and flight computers.

All the main core stage structures for Artemis II, the first mission with astronauts, have been built and are being outfitted with electronics, feedlines, propulsion systems, and other components.

NASA’s Lunar Gateway to be equipped with Instruments to Forecast Weather Forecast for Artemis Missions

 

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – One of the first things people want to know before taking a trip is what the weather will be like wherever they are headed.

For Artemis astronauts traveling on missions to the Moon, two space weather instrument suites, NASA’s HERMES and ESA’s ERSA, will provide an early forecast. Weather in this case means energized, subatomic particles and electromagnetic fields hurtling through the solar system.

NASA releases Artemis Mission Plan to Land on Moon in 2024

 

NASA - National Aeronautics and Space AdministrationWashington, D.C. – Following a series of critical contract awards and hardware milestones, NASA has shared an update on its Artemis program, including the latest Phase 1 plans to land the first woman and the next man on the surface of the Moon in 2024.

In the 18 months since NASA accepted a bold challenge to accelerate its exploration plans by more than four years and establish sustainable exploration by the end of the decade, the agency has continued to gain momentum toward sending humans to the Moon again for the first time since the last Apollo lunar mission in 1972.

NASA tests SLS Booster for improvement for Artemis Missions

 

NASA - National Aeronautics and Space AdministrationWashington, D.C. – As NASA begins assembling the boosters for the Space Launch System (SLS) rocket that will power the first Artemis mission to the Moon, teams in Utah are evaluating materials and processes to improve rocket boosters for use on missions after Artemis III.

NASA completed a full-scale booster test for NASA’s Space Launch System rocket in Promontory, Utah, on September 2nd, 2020. NASA and Northrop Grumman, the SLS booster lead contractor, will use data from the test to evaluate the motor’s performance using potential new materials and processes that can be incorporated into future boosters.

NASA and Northrop Grumman successfully complete the Flight Support Booster-1 (FSB-1) test in Promontory, Utah, on Sept. 2. The full-scale booster firing was conducted with new materials and processes that may be used for NASA’s Space Launch System (SLS) rocket boosters. (NASA)

NASA’s Artemis I Rocket completes Four Green Runs

 

NASA - National Aeronautics and Space AdministrationHuntsville, AL – The Space Launch System (SLS) rocket core stage for the Artemis I lunar mission has successfully completed its first four Green Run tests and is building on those tests for the next phase of checkout as engineers require more capability of the hardware before hot-firing the stage and its four powerful engines.

Green Run is a demanding series of eight tests and nearly 30 firsts: first loading of the propellant tanks, first flow through the propellant feed systems, first firing of all four engines, and first exposure of the stage to the vibrations and temperatures of launch.

The Space Launch System (SLS) rocket is completing the Green Run test for the rocket’s core stage, shown installed on the top left side of the B-2 Test Stand at NASA’s Stennis Space Center near Bay St. Louis, Mississippi. For Green Run, the team is completing a series of eight tests culminating with Test 8, a full-up hot fire test that lasts eight minutes. Flames from the test will exit out of the yellow flame bucket shown here on the north side of the test stand. (NASA/Stennis)

NASA installs Robotic Tool Stowage unit aboard International Space Station

 

NASA - National Aeronautics and Space AdministrationGreenbelt, MD – NASA says storage is just as important aboard the International Space Station as it is on Earth. While the space station is about the size of a football field, the living space inside is much smaller than that.

Just as you wouldn’t store garden tools in a house when you could store them in a shed outside, astronauts now have a “housing unit” in which they can store tools for use on the exterior of the space station.

The Mobile Base System moves on the Mobile Transporter rail car along truss rails covering the length of the space station. It provides a movable platform for Canadarm2 and Dextre and can access any of eight worksites that feature power connections. (NASA)
