SLS Green Run Team Powers Up Core Stage for Wet Dress Rehearsal

NASA and Boeing engineers have powered up the Space Launch System rocket core stage to continue with the seventh test, wet dress rehearsal at the agency’s Stennis Space Center near Bay St. Louis, Mississippi. The NASA and Boeing team plan to fully load the stage’s liquid hydrogen and liquid oxygen tanks this week. This test demonstrates the ability to load the core stage with cryogenic propellant.

 

Following a partial loading of the tanks earlier this month, the team is now resuming the seventh of the eight tests in the Green Run series being completed with the Artemis I core stage. Upon completion of the wet dress rehearsal, the team will spend a few days analyzing data to determine if NASA is ready to proceed with the final Green Run test: the hot fire when all four engines will ignite simulating the countdown and launch of the Artemis I mission.

 

NASA will set a date for the hot fire after the wet dress rehearsal is complete. For an update at the conclusion of wet dress rehearsal, check back at this blog or visit the Green Run web site: https://www.nasa.gov/artemisprogram/greenrun

NASA, Canadian Space Agency Formalize Gateway Partnership for Artemis Program

NASA and the Canadian Space Agency (CSA) finalized an agreement between the United States and Canada to collaborate on the Gateway, an outpost orbiting the Moon that will provide vital support for a sustainable, long-term return of astronauts to the lunar surface as part of NASA’s Artemis program. This Gateway agreement further solidifies the broad effort by the United States to engage international partners in sustainable lunar exploration as part of the Artemis program and to demonstrate technologies needed for human missions to Mars.

Under this agreement, CSA will provide the Gateway’s external robotics system, including a next-generation robotic arm, known as Canadarm3. CSA also will provide robotic interfaces for Gateway modules, which will enable payload installation including that of the first two scientific instruments aboard the Gateway. The agreement also marks NASA’s commitment to provide two crew opportunities for Canadian astronauts on Artemis missions, one to the Gateway and one on Artemis II.

Green Run Wet Dress Rehearsal Update

NASA is proceeding with Green Run testing of the Artemis I core stage at the agency’s Stennis Space Center near Bay St. Louis, Mississippi. After refining the procedures for test operations, NASA is planning to conduct a full wet dress rehearsal next week.

On Dec. 5, engineers powered up the stage to start wet dress rehearsal testing and successfully conducted an initial propellant loading on Dec. 7. This partial loading showed the stage performed well and has given the NASA and Boeing team a valuable opportunity to practice loading procedures and monitor the Artemis I core stage as it is exposed to cryogenic, or supercold, liquids for the first time. While performing operations to load liquid oxygen propellant earlier in the day, data showed the temperature of the propellant was warmer than planned, and the NASA and Boeing team paused the test to take a closer look at the data before committing to loading all 700,000 gallons of propellant. The team proceeded with loading a limited amount of liquid hydrogen, cooled to minus 423 degrees Fahrenheit, without any issues.

After an integrated assessment of the core stage and the facility, the team identified processes and equipment that could be modified to keep the liquid oxygen at the proper temperature during delivery to the stage. The team is now implementing these changes while Stennis personnel replenish propellants and other commodities needed to run the full wet dress rehearsal.

The wet dress rehearsal is the seventh of eight Green Run tests and the last before the hot fire test of the entire stage. The purpose of the wet dress rehearsal is to complete propellant loading operations and thoroughly check out the core stage’s complex systems as they are exposed to cryogenic propellant for the first time. Following wet dress rehearsal, the team will analyze the data and set a date for the hot fire test

Tune in to nasa.gov/live at 12 p.m. EST Thursday, Dec. 10 to for more details on the upcoming test in the Green Run testing series for the Space Launch System (SLS) rocket’s core stage that will fly on the agency’s Artemis I mission.

NASA Names Artemis Team of Astronauts Eligible for Early Moon Missions

NASA has selected 18 astronauts from its corps to form the Artemis Team and help pave the way for the next astronaut missions on and around the Moon as part of the Artemis program.

Vice President Mike Pence introduced the members of the Artemis Team Wednesday during the eighth National Space Council meeting at NASA’s Kennedy Space Center in Florida.

“I give you the heroes who will carry us to the Moon and beyond – the Artemis Generation,” said Vice President Mike Pence. “It is amazing to think that the next man and first woman on the Moon are among the names that we just read. The Artemis Team astronauts are the future of American space exploration – and that future is bright.”

Green Run Wet Dress Rehearsal Update

NASA successfully powered up the core stage at the agency’s Stennis Space Center near Bay St. Louis, Mississippi on Dec. 5 and started the process to load propellant for the first time into the Space Launch System (SLS) rocket core stage Dec. 7. To complete this wet dress rehearsal exercise, cryogenic propellants are transferred from facility barge systems to the core stage. To test propellant loading procedures, engineers successfully loaded a small amount of liquid hydrogen into the core stage without any issues. Then, they paused propellant loading to review data and adjust procedures before loading additional propellant.

Operations are continuing, and the team will refine the procedures and resume the wet dress rehearsal test in the coming days. The core stage performed well, and there are no issues with the stage, the B-2 test stand, or other facilities at Stennis.

The purpose of the test is to complete first-time operations using the new facilities and new rocket stage and adjust processes as necessary. The wet dress rehearsal is the seventh of eight Green Run tests being performed on the Artemis I core stage. Check back at this blog for more updates.

NASA ‘Go’ for Green Run Wet Dress Rehearsal

In a test readiness review on Friday, Dec. 4, NASA gave the “go” to start the next Green Run test, wet dress rehearsal, for NASA’s Artemis I Space Launch System (SLS) rocket core stage. The wet dress rehearsal is the first time the stage will be fully loaded with propellants and is planned to last approximately 48 hours. The test will begin on Saturday, Dec. 5 by powering up the core stage avionics, and engineers plan to load more than 700,000 gallons of cryogenic, or supercooled, propellant on Monday, Dec. 7.

This is the seventh of eight Green Run tests for the Artemis I core stage built by Boeing and the four RS-25 engines manufactured by Aerojet Rocketdyne. For this test, the team will focus on the core stage’s first exposure to cryogenic propellants. Six barges filled with liquid hydrogen and oxygen are supplying the propellant to the B-2 test stand at NASA’s Stennis Space Center near Bay St. Louis, Mississippi where the Green Run tests are taking place.

Engineers will monitor the core stage’s giant propellant tanks and complex propulsion systems for potential leaks or other issues that stages have historically experienced the first time cryogenic propellants are loaded. To prepare for Artemis launches, engineers also will put the stage through scenarios it might experience on the pad before lift-off. They plan to conduct two different holds in the countdown timeline while the stage is in a launch-ready state. This provides an opportunity to observe how the stage would respond if the countdown was paused during the upcoming hot fire test or a future Artemis launch. At the end of the test, all the propellant will be drained following similar procedures that would be used during a launch scrub on the pad. After draining the tanks, the team will review the test data before proceeding with plans for the hot fire test.
