NASA Program Update

Teams have rescheduled the return of the Space Launch System rocket and Orion spacecraft to the Vehicle Assembly Building (VAB) at NASA’s Kennedy Space Center to Friday, July 1 due a concern with the condition of the crawlerway that leads from Launch Pad 39B to the VAB. First motion is now planned for 6 p.m. EDT.

This afternoon, teams conducted a series of conditioning efforts driving the massive transporter up and down the slope leading to the launch pad. The inclined pathway must be precisely level with an even distribution of the rocks that make up the crawlerway in order to support the load of the mobile launcher and rocket that it will carry.

Teams will continue grating, or sifting, the crawlerway overnight and the rocket and spacecraft remain in a safe configuration.

KENNEDY SPACE CENTER, Fla. (NASA PR) — NASA will hold a media teleconference at 3 p.m. EDT on Monday, April 18, to discuss the status of the next wet dress rehearsal test of the agency’s Space Launch System (SLS) rocket and Orion spacecraft at Launch Complex 39B at the agency’s Kennedy Space Center in Florida ahead of the uncrewed Artemis I lunar mission.

Due to upgrades required at an off-site supplier of gaseous nitrogen used for the test, NASA will take advantage of the opportunity to roll SLS and Orion back to the Vehicle Assembly Building to replace a faulty upper stage check valve and a small leak on the tail service mast umbilical. During that time, the agency also will review schedules and options to demonstrate propellant loading operations ahead of launch.

The teleconference will stream live on the agency’s website.

Teleconference participants include:

  • Tom Whitmeyer, deputy associate administrator for common exploration systems development, NASA Headquarters in Washington
  • Charlie Blackwell-Thompson, Artemis launch director, NASA Exploration Ground Systems program, Kennedy
  • Mike Sarafin, Artemis mission manager, NASA Headquarters

Through Artemis missions, NASA will land the first woman and the first person of color on the Moon, paving the way for a long-term lunar presence and serving as a steppingstone to send astronauts to Mars.

Texas Gov. Abbott Vows to Fight for SpaceX to Launch From Boca Chica

Greg Abbott

by Douglas Messier
Managing Editor

Texas Gov. Greg Abbott has vowed to fight for SpaceX to receive federal approval to launch its Super Heavy/Starship system from the company’s Starbase facility in Boca Chica, Texas. Rio Grande Guardian reports:

Asked by veteran broadcaster Ron Whitlock of Ron Whitlock Reports whether he is concerned about losing SpaceX, Abbott said:

“What I am going to do if Biden interferes with the ability of SpaceX to launch from Boca Chica; I am going to be working every step of the way to make sure that they are going to be able to launch from Boca Chica. We heard the vision from Mr. Patel himself about what they are working on and our job is to make sure they are able to achieve their vision. And I have worked with Elon Musk very closely with regard to Tesla and the Giga factory in Austin, Texas. And we will be working with him very closely, every step of the way in Boca Chica for the future of SpaceX. We want that future and that vision to come from Boca Chica, from Brownsville, Texas.”

Whitlock followed up with: “And not to Florida?” Abbott responded: “Correct.”

Whitlock interviewed Abbott at an economic development event held recently at the Port of Brownsville. Since this event, SpaceX has learned that its application to expand its Boca Chica rocket launching site has hit a new hurdle.

KENNEDY SPACE CENTER, Fla. (NASA PR) — In continued preparations for the Artemis I wet dress rehearsal test, with tanking targeted for Monday, teams encountered an issue maintaining helium purge pressure on the upper stage engine after change-out of a regulator on the mobile launcher. The RL10 engine on the upper stage uses helium to purge the engine and also to activate upper stage valves during wet dress rehearsal operations.

After initial troubleshooting, the team reestablished normal helium purge, and is continuing work to determine the cause of a restriction in the helium flow. Engineers will conduct troubleshooting tomorrow to confirm and characterize system performance. If needed, the mission management team will meet Sunday to disposition any adjustments in the procedures or modifications in test objectives as necessary. After the wet dress rehearsal test, SLS and Orion will return to the Vehicle Assembly Building, and engineers will conduct additional inspections of the related flight systems to further evaluate system performance. The Space Launch System rocket, the Orion spacecraft, and the supporting ground system elements remain in stable condition.

The countdown for the two-day test is currently slated to begin with call to stations beginning at 5 pm EDT on Saturday, April 9 with T-0 planned for 2:40 pm on Monday, April 11. While engineers investigate the issue, teams continue to refine the test schedule to account for insights gained during the previous runs and activities, or test objectives, that were completed earlier this week and no longer need to be included in the next test run, such as configuring ground support equipment. Pending additional analysis, NASA expects to have a forward plan tomorrow for wet dress rehearsal testing.

Check back at this blog for an update on wet dress rehearsal testing for the Artemis I mission. NASA is streaming live video of the rocket and spacecraft on the Kennedy Newsroom YouTube channel. Real-time updates will be provided on the Exploration Ground Systems Twitter account with “go” for tanking.

KENNEDY SPACE CENTER, Fla. (NASA PR) — The Artemis I team has ended today’s attempt at the wet dress rehearsal  test at 5 p.m. The countdown ended after partially loading liquid oxygen into the Space Launch System core stage tank. This provided the teams a valuable opportunity for training and to make sure modeled loading procedures were accurate. This was the first time using new systems at NASA’s Kennedy Space Center Launch Complex 39B. The team was able to monitor the Artemis I core stage as it was exposed to cryogenic liquids and gather data that will inform updates to propellant loading procedures.

After troubleshooting a temperature limit issue for the liquid oxygen, which delayed the countdown by several hours, the team successfully developed a new procedure for loading the liquid oxygen and filled the tank to 50 percent. Liquid oxygen is an extremely cold, or cryogenic, propellant that is maintained at minus 297 degrees Fahrenheit.

During chilldown of the lines in preparation for loading the liquid hydrogen, the teams encountered an issue with a panel on the mobile launcher that controls the core stage vent valve. The purpose of the vent valve is to relieve pressure from the core stage during tanking. Given the time to resolve the issue as teams were nearing the end of their shifts, the launch director made the call to stop the test for the day. A crew will investigate the issue at the pad, and the team will review range availability and the time needed to turn systems around before making a determination on the path forward.

The wet dress rehearsal is the last major test before launch. This test allows the team to practice propellant loading and thoroughly check out the Artemis I rocket systems as they are exposed to cryogenics.

KENNEDY SPACE CENTER, Fla. (NASA Update) — Teams have decided to scrub tanking operations for the wet dress rehearsal due to loss of ability to pressurize the mobile launcher. The fans are needed to provide positive pressure to the enclosed areas within the mobile launcher and keep out hazardous gases. Technicians are unable to safely proceed with loading the propellants into the rocket’s core stage and interim cryogenic propulsion stage without this capability.

Teams will now meet to determine next steps and establish a go forward plan. The next opportunity to proceed into tanking is Monday, April 4. Teams will discuss range and commodity availability as part of the forward plan.
