NASA Insignia and American Flag Applied to Orion for Artemis I

Technicians with the lead contractor for Orion, Lockheed Martin, adhered the NASA insignia, known as the “meatball,”  and an American Flag to the back shell of the spacecraft’s crew module for Artemis I. Final assemblies are well underway for Orion as teams progress toward next year’s launch. The spacecraft will soon be fueled and fitted with the launch abort system and other ground system elements in preparation to take its place atop the powerful Space Launch System rocket.

SLS Green Run Testing Status Update

NASA is progressing through the Green Run test series for the Space Launch System (SLS) rocket at the agency’s Stennis Space Center in Mississippi and has completed six of the eight tests. The team is preparing to stand down for another tropical weather system that is heading to the area. The pause in work comes ahead of the most complex tests: wet dress rehearsal, when propellant will be loaded for the first time, and hot fire, when all four engines will be fired and every system within the stage will operate. During the pause, engineers will continue to assess data from recent tests to ensure the team is ready to proceed to the next phase of testing. Green Run testing is a complex series of tests to methodically and thoroughly check all the rocket’s core stage systems together for the first time to ensure the stage is ready for flight. Check back at this blog for an update on adjusted dates for the Green Run wet dress rehearsal and hot fire tests, after the storm has passed.

Mobile Launcher Arrives at Launch Pad 39B for Tests, Preps for Artemis I

The Exploration Ground Systems and Jacobs teams rolled the mobile launcher, atop crawler-transporter 2, out of the Vehicle Assembly Building for its slow trek to Launch Pad 39B at Kennedy Space Center in Florida on Oct. 20.

The roll began just after midnight, and the mobile launcher arrived at the top of the pad Tuesday morning. This trek to the pad will help prepare the launch team for the actual wet dress rehearsal and launch of SLS and Orion on Artemis I next year. The wet dress rehearsal is when SLS and Orion will be rolled out to the pad atop the mobile launcher to practice fueling operations a couple months before launch. The last time the mobile launcher was rolled to the pad was in December 2019.

During its two-week stay at the pad, engineers will perform several tasks, including a timing test to validate the launch team’s countdown timeline, and a thorough, top-to-bottom wash down of the mobile launcher to remove any debris remaining from construction and installation of the umbilical arms.

Orion Solar Array Wing Installation Complete for Artemis I

Artemis I Orion Solar Wing Installation Complete

Teams from NASA, Lockheed Martin, the European Space Agency (ESA), Airbus Defence, and Airbus Netherlands have completed the meticulous installation of Orion’s four solar array wings. The arrays will supply energy to the service module that will power and propel the spacecraft during NASA’s Artemis I mission. They were fitted onto the European Service Module (ESM) inside the Neil Armstrong Operations and Checkout Building at the agency’s Kennedy Space Center in Florida.

Activities on the spacecraft continue to move forward — the next set of final installations include the spacecraft adapter jettison fairings, which enclose the service module, and forward bay cover, protecting the upper part of Orion including its parachutes throughout its mission. Once complete, the spacecraft will begin its journey through Kennedy to be integrated with its launch abort system and ultimately, the Space Launch System (SLS) rocket for launch from Kennedy’s Launch Pad 39B.

Artemis I Networks for Communication and Navigation

Artemis I will demonstrate NASA’s networks’ comprehensive services for journeys to lunar orbit. The mission requires all three of NASA’s major networks to work in tandem, providing different communications and tracking service levels as Orion leaves Earth, orbits the Moon, and returns safely home.

Communications services allow flight controllers in mission control centers to send commands to the spacecraft and receive data from Orion and SLS systems. Tracking, or navigation, services enable the flight controllers to see where the spacecraft are along their trajectory through space.

SLS Core Stage Passes Simulated Countdown Test

Engineers at NASA’s Stennis Space Center near Bay St. Louis, Mississippi, completed a simulated launch countdown sequence on Oct. 5 for the sixth test of the eight-part core stage Green Run test series for NASA’s Space Launch System (SLS) rocket.

The rocket’s core stage has three flight computers and avionics systems to help launch and guide NASA’s Artemis missions to the Moon. During the simulated countdown, NASA engineers and technicians, along with prime contractors Boeing, and Aerojet Rocketdyne, monitored the stage to validate the timeline and sequence of events leading up to the test, which is similar to the countdown for the Artemis I launch.

The countdown sequence for an actual Artemis launch begins roughly two days prior to liftoff. In addition to all the procedures leading up to the ignition of the four RS-25 engines, the SLS core stage requires about six hours to fully load fuel into the two liquid propellant tanks. The simulated countdown sequence test at Stennis began at the 48-hour mark as if the stage was first powered up before liftoff. Engineers then skipped ahead in the sequence to monitor the stage and procedures of the stage 10 minutes before the hot fire. The simulated countdown sequence is one of the final tests of the SLS Green Run campaign. The series of tests is designed to gradually bring the rocket stage and all its systems to life for the first time.

Artemis I Rocket and Spacecraft Receive “Worm” Welcome

NASA worm and ESA logo on Orion spacecraft

NASA is headed back to the Moon as part of the Artemis program – and the agency’s “worm” logo will be along for the ride on the first integrated mission of the powerful Space Launch System (SLS) rocket and Orion spacecraft. Teams at NASA’s Kennedy Space Center in Florida have applied the historic logo in bright red on visible parts of the Artemis I rocket and spacecraft.

Artemis Plan to Land First Woman, Next Man on Moon in 2024

Following a series of critical contract awards and hardware milestones, an update on NASA’s Artemis program is now available, 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 mission in 1972.

The document captures Artemis progress to date, identifying the key science, technology and human missions as well as the commercial and international partnerships that will ensure we continue to lead in exploration and achieve our ambitious goal to land astronauts on the Moon.

Artemis I Preparations Stack Up

Technicians with NASA’s Exploration Ground Systems rehearse booster stacking operations inside the Vehicle Assembly Building (VAB) at the agency’s Kennedy Space Center in Florida on Monday, Sept.14, in preparation for the Artemis I launch. The team is using full-scale replicas of booster segments, referred to as pathfinders, for the practice exercise in one of the tallest sections, or high bays, of the VAB built for stacking rockets. As part of the rehearsal, a pathfinder for an aft segment, the very bottom of the stack, was prepared in High Bay 4. Then, a team of crane operators moved the segment into High Bay 3, where it was placed on the mobile launcher. Careful measurements were taken before the team added a center segment to the stack.

The actual Space Launch System (SLS) booster segments will be stacked on the mobile launcher later this year, following completion of Green Run testing of the rocket’s core stage – a series of eight tests taking place at the agency’s Stennis Space Center in Mississippi.

NASA Completes Fifth Green Run Test for First Artemis Moon Rocket

Engineers have completed the fifth of eight Green Run tests on the core stage of NASA’s new Space Launch System (SLS) rocket, continuing progress toward a hot fire test this fall. Operators evaluated the stage’s thrust vector control system on the historic B-2 Test Stand at NASA’s Stennis Space Center near Bay St. Louis, Miss., on Sept. 13. The test provided critical verification of the control system and its related hydraulics as operators moved the stage’s four RS-25 engines as they must move during flight to steer the rocket and maintain a proper trajectory. The stage now is set for two more tests – a simulated countdown demonstration and wet dress rehearsal – directly leading to the hot fire of all four RS-25 engines, as during an actual flight.

In the countdown demonstration, engineers will simulate the launch countdown and procedures to validate the established timeline and sequence of events. In the wet dress rehearsal, engineers will conduct another countdown exercise and actually load, control and drain more than 700,000 gallons of cryogenic propellants to ensure all is set for the final test of the Green Run series. The concluding test will activate all stage systems and fire the four RS-25 engines to generate the same combined 1.6 million pounds of thrust that will help launch the SLS rocket when it flies on the Artemis I mission.
