NEW ORLEANS (NASA PR) — Engineers and technicians at NASA’s Michoud Assembly Facility in New Orleans have structurally mated the first of four RS-25 engines to the core stage for NASA’s Space Launch System (SLS) rocket that will help power the first Artemis mission to the Moon.
Integration of the RS-25 engines to the recently completed core stage structure is a collaborative, multistep process for NASA and its partners Boeing, the core stage lead contractor, and Aerojet Rocketdyne, the RS-25 engines lead contractor. To complete the installation, the technicians will now integrate the propulsion and electrical systems.
The installation process will be repeated for each of the four RS-25 engines. The four RS-25 engines used for Artemis I were delivered to Michoud from Aerojet Rocketdyne’s facility at NASA’s Stennis Space Center near Bay St. Louis, Mississippi, in June.
The engines, located at the bottom of the core stage in a square pattern, are fueled by liquid hydrogen and liquid oxygen. During launch and flight, the four engines will fire nonstop for 8.5 minutes, emitting hot gases from each nozzle 13 times faster than the speed of sound. The completed core stage with all four engines attached will be the largest rocket stage NASA has built since the Saturn V stages for the Apollo Program.
NASA is working to land the first woman and next man on the Moon by 2024. SLS is part of NASA’s backbone for deep space exploration, along with Orion and the Gateway in orbit around the Moon. SLS is the only rocket that can send Orion, astronauts and supplies to the Moon on a single mission.
NEW ORLEANS (NASA PR) — NASA finished assembling and joining the main structural components for the largest rocket stage the agency has built since the Saturn V that sent Apollo astronauts to the Moon. Engineers at the agency’s Michoud Assembly Facility in New Orleans connected the last of the five sections of the Space Launch System (SLS) rocket core stage on Sept. 19. The stage will produce 2 million pounds of thrust to send Artemis I, the first flight of SLS and NASA’s Orion spacecraft to the Moon.
NEW ORLEANS (NASA PR) — NASA and Boeing have completed the majority of outfitting for the core stage engine section for the first flight of the agency’s new Space Launch System (SLS) rocket. The engine section, located at the bottom of the 212-foot-tall core stage, is one of the most complex parts of the rocket. Technicians at NASA’s Michoud Assembly Facility in New Orleans have installed more than 500 sensors, 18 miles of cables, and numerous other critical systems for mounting, controlling and delivering fuel to the rocket’s four RS-25 engines.
The core stage tanks hold cryogenic liquid hydrogen and liquid oxygen that are combusted by the engines to produce 2 million pounds of thrust to help send SLS to space for missions to the Moon. On the exterior of the engine section, technicians attached cork insulation for thermal protection and painted it white as well as finishing up other systems including fittings where solid rocket boosters attach.
Next, NASA and Boeing, the SLS prime contractor, will add the boat-tail to the bottom of the engine section and finish up some outfitting, integration and avionics functional testing. The boat-tail is an extension that fits on the end of the engine section. The engines are inserted through openings in the boat-tail, which acts much like a fairing to cover and protect most of engines’ critical systems.
The engines are mounted inside the engine section, and only the RS-25 engine nozzles extend outside the boat-tail. The team is using lessons learned building and outfitting the engine section for the first integrated flight of SLS to accelerate outfitting of the engine section for the second SLS mission. The primary structure of the core stage engine section for the second SLS flight has been built and covered with primer as it prepares for its outfitting and is visible in this image, just behind the first engine section.
Editor’s Note: Last week the space agency said it is reassessing plans to conduct the first SLS/Orion flight during the first half of 2020.
WASHINGTON (NASA PR) — NASA will soon return humans to the Moon for decades to come, and the system that will transport astronauts from Earth to the Gateway near the Moon is literally coming together. Building on progress in 2018, most of the major manufacturing for the first mission is complete, and this year, teams will focus on final assembly, integration, and testing, as well as early work for future missions. NASA is focused on launching the first mission, Exploration Mission-1 (EM-1),
The NASA Transition Authorization Act of 2017 (P.L. 115-10) provided for an ISS Transition Report under section 303:
The Administrator, in coordination with the ISS management entity (as defined in section 2 of the National Aeronautics and Space Administration Transition Authorization Act of 2017), ISS partners, the scientific user community, and the commercial space sector, shall develop a plan to transition in a step-wise approach from the current regime that relies heavily on NASA sponsorship to a regime where NASA could be one of many customers of a low-Earth orbit non-governmental human space flight enterprise.
KENNEDY SPACE CENTER, Fla. (NASA PR) — Engineers preparing NASA’s deep space exploration systems to support missions to the Moon, Mars, and beyond are gearing up for a busy 2018. The agency aims to complete the manufacturing of all the major hardware by the end of the year for Exploration Mission-1 (EM-1), which will pave the road for future missions with astronauts.
Planes, trains, trucks and ships will move across America and over oceans to deliver hardware for assembly and testing of components for the Orion spacecraft and the Space Launch System (SLS) rocket while teams at NASA’s Kennedy Space Center in Florida prepare the Ground Systems infrastructure. Testing will take place from the high seas to the high skies and in between throughout the year and across the country, not only in support of EM-1, but also for all subsequent missions. (more…)
It seems that nothing so becomes a politician’s public life like the announcement that he or she is leaving it.
George Washington’s decision in 1796 to not seek a third term as president is widely hailed as the ultimate example of a small-r republican virtue of restraint the general demonstrated throughout his public life. Americans trusted Washington with power because they knew he would exercise it wisely and, that when the time came, he would walk away. Voluntarily.
In an age when many kings claimed a hereditary right to rule for life with absolute authority, relinquishing power was an astounding act. But Washington, a master of exits in war and peace, knew it was time to go. In so doing, he set a two-term precedent for the presidency that would stand for 144 years.
More recently, we’ve seen another result of what happens when politicians decide they’ve had enough: candor. Sens. Bob Corker (R-TN) and Jeff Flake (R-AZ) both launched fiery broadsides at the current occupant of Washington’s old office — and a member of their own party, no less — upon announcing they would not seek re-election next year.
NASA would receive $19.653 billion for fiscal year 2017 under an Omnibus spending bill released on Monday by Congressional appropriators, an increase of more than $600 million requested by the Obama Administration. NASA received just under $19.3 billion in FY 2016.
The bill was released seven months into the 2017 fiscal year. The government has been operating on continuing resolutions since the year began last Oct. 1.
