Washington, 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.
Huntsville, 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.
Washington, 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.
Edwards, CA – Rocket off course? NASA says it could be a slosh problem.
Propellant slosh, to be exact. The motion of propellant inside a rocket-based launch vehicle or spacecraft tank is an ever-present, vexing problem for spaceflight. Not only can it make gauging the amount of available propellant difficult, but the volatile waves of liquid can literally throw a rocket off its trajectory.
“To understand why it’s such a critical issue, it’s important to realize that for most launch vehicles, liquid propellant initially makes up nearly 90% of the vehicle mass,” explained Kevin Crosby of Carthage College in Kenosha, Wisconsin.
Florida – NASA has stacked the first piece of the Space Launch System (SLS) rocket on the mobile launcher in preparation for the Artemis I launch next year. At NASA’s Kennedy Space Center in Florida, engineers lowered the first of 10 segments into place November 21st, 2020 for the twin solid rocket boosters that will power the first flight of the agency’s new deep space rocket.
Artemis I will be an uncrewed flight to test the SLS rocket and Orion spacecraft as an integrated system ahead of crewed flights to the Moon with the Artemis program.
Washington, 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.
Huntsville, AL – As part of the Artemis program, NASA is returning astronauts to the Moon where we will prepare for human exploration of Mars. Additive manufacturing, or 3D printing, experts from NASA, industry, and academia are pioneering methods to print the rocket parts that could power those journeys.
NASA’s Rapid Analysis and Manufacturing Propulsion Technology project, or RAMPT, is advancing development of an additive manufacturing technique to 3D print rocket engine parts using metal powder and lasers.
Washington, 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.
Washington, D.C. – Space technology developed by and for NASA has made its way into cars and even onto the NASCAR track. Future collaborations with the auto industry and car manufacturers could change how we get from point A to point B. NASA helped drive the following five auto innovations.
NASA has a long history of transferring technology to the private sector. The agency’s Spinoff publication profiles NASA technologies that have transformed into commercial products and services, demonstrating the broader benefits of America’s investment in its space program. Spinoff is a publication of the Technology Transfer program in NASA’s Space Technology Mission Directorate.
Huntsville, 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.
