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.
WASHINGTON (NASA PR) — NASA has taken the next steps toward building Space Launch System (SLS) rocket core stages to support as many as 10 Artemis missions, including the mission that will carry the first woman and next man to the Moon by 2024.
HOUSTON (NASA PR) — As we prepare to send the first woman and next man to the Moon and on to Mars, NASA, with support from the University of Houston, has been working to develop advanced radiation detectors to better protect astronauts and vital spacecraft systems during solar storms. The detectors are based on technology that was originally developed by the European Organization for Nuclear Research (CERN) to detect particle collisions in high-energy physics experiments. Storms emanating from our Sun release invisible, high energy particles, also called ionizing radiation, into space at relativistic speeds that can damage spacecraft electronics and systems, and impact the health of astronauts.
Japan Aerospace Exploration Agency (JAXA) and National Aeronautics and Space Administration (NASA)
Joint Statement on Cooperation in Lunar Exploration
During their September 24, 2019, meeting at JAXA Headquarters in Tokyo, NASA Administrator James Bridenstine and JAXA President Hiroshi Yamakawa welcomed the ongoing engagement between their agencies to realize JAXA’s participation in NASA’s Artemis program and vision for the participation of Japanese astronauts in lunar exploration.
KENNEDY SPACE CENTER, Fla., July 20, 2019 (Lockheed Martin PR) — The goal of humans again walking on the Moon is one giant leap closer. Lockheed Martin (NYSE: LMT) has completed building the capsule for NASA’s Orion spacecraft. The crew module capsule for the uncrewed Artemis 1 mission to the Moon has been stacked on top of the Orion service module, which was also recently finished.
HOUSTON (NASA PR) — In mission control at Johnson Space Center in Houston, flight controllers simulated part of Orion’s uncrewed flight to the Moon for Artemis 1. The team executed an outbound trajectory correction, a maneuver that will be needed to make sure Orion is on the right path after the Space Launch System performs the Trans-Lunar Injection burn that sends the spacecraft out of Earth orbit and toward the Moon. As Orion travels toward the Moon over the course of several days, flight controllers will command Orion from the ground six times to correct its trajectory to ensure the spacecraft can fly by the Moon at the correct time and place. The flight control team is preparing for Artemis missions by refining and practicing procedures they will use on the ground to command and control Orion on its missions to the Moon.
