NEW ORLEANS (NASA PR) — On Monday, Dec. 9, NASA Administrator Jim Bridenstine showed off the Space Launch System liquid-fueled rocket stage that will send the first Artemis mission to space. The core stage, built at NASA’s Michoud Assembly Facility in New Orleans, is the largest NASA has produced since the Apollo Program.
NASA and the Michoud team will shortly send the first fully assembled, 212-foot-tall core stage to the agency’s Stennis Space Center near Bay St. Louis, Mississippi aboard the Pegasus barge for final tests.
HUNTSVILLE, Ala. (NASA PR) — Engineers at NASA’s Marshall Space Flight Center in Huntsville, Alabama, on Dec. 5 deliberately pushed the world’s largest rocket fuel tank beyond its design limits to really understand its breaking point. The test version of the Space Launch System rocket’s liquid hydrogen tank withstood more than 260% of expected flight loads over five hours before engineers detected a buckling point, which then ruptured. Engineers concluded the test at approximately 11 p.m.
NASA’s culture of excessive optimism and its tendency to underestimate technical challenges combine with funding instability to cause cost overruns and schedule delays, according to a new report from the NASA Office of Inspector General (OIG).
The document identified NASA’s management of major projects as one of the space agency’s top seven performance challenges. [Full Report]
HUNTSVILLE, Ala. (NASA PR) — Engineers are preparing to push a test article identical to the world’s largest rocket fuel tank beyond its design limits and find its breaking point during upcoming tests at NASA’s Marshall Space Flight Center in Huntsville, Alabama.
With NASA’s mobile launcher at Launch Pad 39B for final verification and testing, the agency’s Exploration Ground Systems (EGS) team has completed another critical set of tests, bringing the agency even closer to the first integrated launch of the Space Launch System (SLS) rocket and Orion spacecraft for the Artemis I mission. Over the course of two weekends, teams tested the flow of cryogenic fluids through the pad’s infrastructure – those systems that will send liquid hydrogen (LH2) and liquid oxygen (LOX) to the rocket at the time of launch.
KENNEDY SPACE CENTER, Fla. (NASA PR) — Teams from NASA’s Exploration Ground Systems and Space Launch System (SLS) practice SLS booster stacking with pathfinders inside Kennedy Space Center’s Vehicle Assembly Building.
The goal of the training, which took place Nov. 18 through Nov. 20, was to practice booster segment mate. Using overhead cranes and booster handling activities, the teams focused on procedures for mating a center segment onto a cylinder that simulated another segment. The exercise was performed around the clock, operating three shifts per day.
SLS will launch the first woman and next man to the Moon by 2024 through the Artemis program. For more information, click here.
MANSFIELD, Ohio (NASA PR) — Almost 1,500 people turned out Sunday, November 24 to watch NASA’s Super Guppy aircraft arrive at Mansfield Lahm Airport with the Orion spacecraft for Artemis I aboard. After viewing exhibits, the crowd gathered at the flight line to await the aircraft.
Once the Guppy touched down, there was a loud cheer from the crowd as it taxied to a stop for the night just as the sun began to set.
The nose of the Guppy was opened at sunrise on Monday, November 25 revealing the packaged Orion spacecraft inside. It has been removed from the aircraft and is loaded onto a large flatbed trailer so it can be transported to NASA’s Plum Brook Station for testing.
Completed in two phases inside the world’s largest vacuum chamber, testing will begin with a thermal test, which will last approximately 60 days, while Orion’s systems are powered-on under vacuum conditions that simulate the space environment.
During this phase, the spacecraft will be subjected to extreme
temperatures, ranging from -250 to 300-degrees Fahrenheit, to replicate
flying in-and-out of sunlight and shadow in space. The second phase is
an electromagnetic interference and compatibility test, lasting about 14
days. This testing will ensure the spacecraft’s electronics work
properly when operated at the same time.
HUNTSVILLE, Ala. (NASA PR) — To launch the Artemis I Moon mission, NASA’s powerful Space Launch System (SLS) rocket must go from 0 to more than 17,000 miles per hour. The rocket’s flight software and avionics systems control all that power to ensure the rocket and NASA’s Orion spacecraft make it to space. The SLS avionics and flight software came a step closer to the Artemis I mission when NASA certified the Systems Integration Laboratory for final integrated avionics and flight software testing Nov. 14.
NEW ORLEANS (NASA PR) — All four RS-25 engines were structurally mated to the core stage for NASA’s Space Launch System (SLS) rocket for Artemis I, the first mission of SLS and NASA’s Orion spacecraft. To complete assembly of the rocket stage, engineers and technicians are now integrating the propulsion and electrical systems within the structure.
The completed core stage with all four RS-25 engines attached is the largest rocket stage NASA has built since the Saturn V stages for the Apollo Program that first sent Americans to the Moon. T
he stage, which includes two huge propellant tanks, provides more than 2 million pounds of thrust to send Artemis I to the Moon. Engineers and technicians at NASA’s Michoud Assembly Facility in New Orleans attached the fourth RS-25 engine to the rocket stage Nov. 6 just one day after structurally mating the third engine.
The first two RS-25 engines were structurally mated to the stage in October. After assembly is complete, crews will conduct an integrated functional test of flight computers, avionics and electrical systems that run throughout the 212-foot-tall core stage in preparation for its completion later this year.
This testing is the first time all the flight avionics systems will be tested together to ensure the systems communicate with each other and will perform properly to control the rocket’s flight.
Integration of the RS-25 engines to the massive core stage 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.
The White House wants Congress to provide more money for the Artemis moon landing program, and to save about $1.5 billion by dropping the requirement that NASA launch the Europa Clipper mission to Jupiter’s icy moon on the Space Launch System (SLS).
HOUSTON, Nov. 5, 2019 (Boeing PR) — Boeing [NYSE: BA] today submitted a proposal to NASA for an integrated Human Lander System (HLS) designed to safely take astronauts to the surface of the moon and return them to lunar orbit as part of the Artemis space exploration program.
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.
WASHINGTON, DC (NASA PR) — The public is invited to join NASA Administrator Jim Bridenstine at 9:40 a.m. EDT Friday, Oct. 25, for an update on the agency’s Artemis program and the critical role international partnerships have in returning astronauts to the Moon and going on to Mars.
Video Caption: Our Artemis program will return humans to the Moon by 2024. Artemis I, the first Artemis mission, will test all of the human rated systems in deep space — including the Orion spacecraft and Space Launch System rocket. This is its 26 day journey… in 30 seconds.
On March 26, Vice President Mike Pence went to Huntsville, Ala., to declare that the Trump Administration would use “any means necessary” to accelerate the return of American astronauts to the surface of the moon by 2024 — four years earlier than planned.
Pence was putting Huntsville-based Marshall Space Flight Center and prime contractor Boeing on notice to get the delayed, over budget Space Launch System (SLS) being built to accomplish that goal back on track. If they didn’t, the administration would find other rockets to do the job.
In his effort to accelerate the Artemis lunar program, however, Pence unintentionally contributed to delays in NASA’s behind schedule effort to launch astronauts to a much closer location: low Earth orbit.
