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.

Orion Test Articles Arrive to Kennedy for Testing on Future Artemis Missions

The Orion Service Module Structural Test Article (SM-STA), composed of the European Service Module (ESM) and Crew Module Adapter (CMA), arrived at NASA’s Kennedy Space Center in Florida following the completion of the test campaign to certify the Orion Service Module for Artemis I. Transported via Super Guppy from Lockheed Martin’s test facility in Denver, Colorado, on Sept. 11, components will now be used in testing for future Artemis missions.

“The Orion SM-STA supported testing in multiple configurations to validate the structural robustness of the vehicle under a variety of conditions that a spacecraft will experience on lunar missions for the Artemis program,” said Rafael Garcia, Orion Test and Verification lead.

At Kennedy, the Orion SM-STA test article will be separated from the CMA test article, and portions of the CMA test article will support qualifications tests in preparation for the Artemis II mission. The test version of the ESM will remain at Kennedy, in order to support future structural qualification tests such as testing what volume of sound and how much shaking the vehicle can handle for future Artemis missions.

When tested together, the full test stack of Orion verified the spacecraft’s structural durability for all flight phases of the Artemis I flight, which is designed to be an opportunity to test the kind of maneuvers and environments the spacecraft will see on future exploration missions. The test structures experienced launch and entry loads tests, intense acoustic vibration force, and shock tests that recreate the powerful blasts needed for critical separation events during flight. A lightning test was performed to evaluate potential flight hardware damage if the vehicle were to be hit by lightning prior to launch.

The Artemis II flight will test a hybrid free return trajectory, which uses the Moon’s gravitational pull as a slingshot to put Orion on the return path home instead of using propulsion. With astronauts aboard the spacecraft, additional validation is required of all vehicle components to certify the capsule prior to proving lunar sustainability with Artemis III and beyond.

The first in a series of increasingly complex missions, Artemis I will test the Orion spacecraft and Space Launch System as an integrated system ahead of crewed flights to the Moon. Under the Artemis program, NASA will land the first woman and the next man on the Moon in 2024.

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.

Orion Spreads its Wings

Inside the Neil Armstrong Operations and Checkout Building high bay at NASA’s Kennedy Space Center in Florida, in preparation for installation on the Artemis I spacecraft, technicians have extended one of the Artemis I solar array wings for inspection on Sept. 10, 2020, to confirm that it unfurled properly and all of the mechanisms functioned as expected. The solar array is one of four panels that will generate 11 kilowatts of power and span about 63 feet. The array is a component of Orion’s service module, which is provided by the European Space Agency and built by Airbus Defence and Space to supply Orion’s power, propulsion, air and water.Inside the Neil Armstrong Operations and Checkout Building at NASA’s Kennedy Space Center in Florida, technicians have extended one of the Artemis I solar array wings on Sept. 10, 2020.

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.

SLS Booster Test Update: Successful Test Completed!

Teams from NASA’s Space Launch System (SLS) and prime contractor Northrop Grumman successfully completed the Flight Support Booster-1 (FSB-1)  ground test at Northrop Grumman’s test facility in Promontory, Utah. Watch a replay of the test on NASA Television or NASA’s YouTube channel. Learn more about the test at https://www.nasa.gov/media/flight-support-booster-test.html

SLS Booster Test Update: Scheduled Hold of Countdown

NASA’s Space Launch System (SLS) Flight Support Booster-1 (FSB-1) test is in a scheduled hold of the countdown. The hold allows time for remaining personnel to evacuate the test area to their designated locations. The test team will also check motor temperatures and confirm data acquisition systems are ready to record. The test fire is scheduled for 1:05 MDT 3:05 p.m. EDT.

SLS Booster Test Update: NASA TV Coverage Underway

Live coverage of NASA’s Space Launch System (SLS) Flight Support Booster-1 (FSB-1) ground test has begun on NASA Television and the agency’s website. The test fire is scheduled to begin at 3:05 EDT. Systems checks are underway for the full-scale, five-segment solid rocket booster ground test at Northrop Grumman’s test facility on Promontory, Utah. This is the first in a series of tests that are examining motor performance for potential new materials and processes that may be incorporated in the booster after the Artemis III lunar mission.
