Artemis Teams Successfully Test Uninterruptible Power for Mobile Launcher 

Teams with NASA’s Exploration Ground Systems (EGS) Program at the agency’s Kennedy Space Center in Florida, successfully tested the new uninterruptible power supply for mobile launcher 1 while it’s in Kennedy’s Vehicle Assembly Building (VAB). This marks the next set of integrated ground systems testing the EGS teams are conducting to prepare for the Artemis II crewed mission.

During this test, engineers turned off the power to the mobile launcher and verified new batteries, which are located in High Bay 3 of the VAB, did not negatively impact any systems. These batteries provide power to the mobile launcher, SLS (Space Launch System) rocket and Orion spacecraft and allow teams to safe all systems in the unlikely event the structure loses power while it’s inside the VAB. There are similar batteries that are used for the same purpose at Launch Complex 39B, from which crewed Artemis missions will launch. 

The Artemis II test flight will be NASA’s first mission with crew under the Artemis campaign, sending NASA astronauts Reid Wiseman, Victor Glover, and Christina Koch, as well as Canadian Space Agency astronaut Jeremy Hansen, on a 10-day journey around the Moon.

Artemis I Orion Spacecraft Returns to Florida

The Artemis I Orion crew module, now known as the Orion Environmental Test Article (ETA), returned to NASA’s Kennedy Space Center in Florida on Dec. 21, 2024, following an 11-month test campaign at the agency’s Neil Armstrong Test Facility in Sandusky, Ohio.

This is not the first time the ETA has been at Kennedy. After splashing down in the Pacific Ocean on Dec. 11, 2022, following its journey around the Moon during the Artemis I mission, the spacecraft was transported by truck from Naval Base San Diego in California to Kennedy’s Multi Payload Processing Facility (MPPF) to be reconfigured from spacecraft to test article and complete a series of crew module functional tests.

Now returned to the spaceport after testing at the Armstrong Test Facility, engineers will begin testing on the ETA in Kennedy’s MPPF to undergo propulsion functional testing, which includes putting the crew module’s twelve reaction control system (RCS) thrusters through a simulated hot fire. RCS thrusters provide control of rotation while in orbit, during re-entry, and certain abort scenarios.

Once testing is complete, the ETA will travel down the road to Kennedy’s Space Systems Processing Facility for an acoustic noise demonstration test that will help improve future acoustic testing for NASA and Lockheed Martin, the agency’s primary contractor for Orion. In addition to undergoing further testing at Kennedy, teams will remove hardware from the ETA for reusability studies that could impact future Artemis missions. With NASA’s Artemis campaign, we are exploring the Moon for scientific discovery, technology advancement, and to learn how to live and work on another world as we prepare for human missions to Mars.

Teams at NASA’s Kennedy Space Center in Florida successfully tested the launch control system, the software used to launch the SLS (Space Launch System) rocket and Orion spacecraft for Artemis Moon missions. The evaluations, which took place in the firing rooms of Kennedy’s Launch Control Center, included testing that software, audio, and imagery displays function well together, as well as practicing a launch pad-abort scenario.

Engineers with Exploration Ground Systems (EGS) Program divided the test into two parts: teams first ensured the software the Artemis launch team uses can handle multiple inputs at the same time. Following software testing, teams performed a launch countdown simulation starting at T-minus 2 hours and 30 minutes until liftoff, which included testing the “abort switch,” a switch only the launch director and assistant launch director can flip in the event an abort at the launch pad is needed.

This marks the next set of integrated ground systems tests NASA completed to prepare for the Artemis II mission. The Artemis II test flight will be NASA’s first mission with crew under the Artemis campaign, sending NASA astronauts Reid Wiseman, Victor Glover, and Christina Koch, as well as CSA (Canadian Space Agency) astronaut Jeremy Hansen, on a 10-day journey around the Moon.

Engineers and technicians inside the Vehicle Assembly Building (VAB) at NASA’s Kennedy Space Center in Florida stacked the first segment of the Artemis II SLS (Space Launch System) rocket boosters onto mobile launcher 1.

Comprising 10 segments total – five segments for each booster – the SLS solid rocket boosters arrived via train to NASA Kennedy in September 2023 from Northrop Grumman’s manufacturing facility in Utah. The booster segments underwent processing in the spaceport’s Rotation, Processing and Surge Facility before being transferred to the NASA’s iconic VAB for stacking operations.

Technicians inside the 525-foot-tall facility used an overhead crane to lift the left aft assembly onto the mobile launcher. Up next, workers will install the right aft assembly, placing it carefully onto the 380-foot-tall structure used to process, assemble, and launch the SLS rocket and Orion spacecraft.

The first components of the Artemis II Moon rocket to be stacked, the solid rocket boosters will help support the remaining rocket segments and the Orion spacecraft during final assembly. At launch, the 177-foot-tall twin solid rocket boosters provide more than 75 percent of the total SLS thrust during liftoff from NASA Kennedy’s Launch Pad 39B.

Since the mobile launcher returned in October from Launch Pad 39B to the Vehicle Assembly Building (VAB) at NASA’s Kennedy Space Center in Florida, work has been underway for upcoming stacking operations of NASA’s SLS (Space Launch System) Moon rocket.

To prepare for launch, the mobile launcher is undergoing optical scans, system checkouts, and umbilical refurbishment, including installation of the aft skirt electrical umbilicals.

The booster segments soon will move from the Rotation, Processing and Surge Facility to the VAB via a transporter. The aft assemblies, or bottom portions of the five segment boosters, will be situated in the facility’s transfer aisle then lifted atop the mobile launcher in High Bay 3.

The examinations and preparations of the mobile launcher and rocket elements lay the groundwork for Artemis II crewed test flight around the Moon.

After spending several months undergoing integrated testing and upgrades at Launch Complex 39B at NASA’s Kennedy Space Center, the agency’s mobile launcher 1 is transported inside the Vehicle Assembly Building in preparation for integration of the Artemis II Moon rocket.

The 4.2-mile trek from Launch Pad 39B to the Vehicle Assembly Building along the crawlerway normally takes eight to 12 hours atop NASA’s crawler-transporter 2, though teams paused the roll operations several times as planned to ensure the operation teams had scheduled breaks and rest. The operation resumed at 1:41 a.m. EDT, Friday, Oct. 4.

Standing 380 feet tall, the mobile launcher – which will be used to assemble, process, and launch the SLS (Space Launch System) rocket and Orion spacecraft – contains all the connection lines – known as umbilicals – and ground support equipment that will provide the rocket and spacecraft with the power, communications, fuel, and coolant necessary for launch. This will be the mobile launcher’s last solo trek out to the launch pad ahead of integration of the Artemis Moon rocket, and it will remain inside the Vehicle Assembly Building until it is ready to return to the pad with the rocket for a tanking test.

The Artemis II test flight will be NASA’s first mission with crew under the Artemis campaign, sending NASA astronauts Victor Glover, Christina Koch, and Reid Wiseman, as well as CSA (Canadian Space Agency) astronaut Jeremy Hansen, on a 10-day journey around the Moon and back.

NASA’s Mobile Launcher Rolls Ahead of Artemis II Preparation

NASA rolled closer to integrating elements of the Artemis II Moon rocket together as teams with the agency’s Exploration Ground Systems Program at Kennedy Space Center in Florida began moving the mobile launcher 1 from Launch Complex 39B along a 4.2 mile stretch back to the Vehicle Assembly Building. First motion of the mobile launcher, atop NASA’s crawler-transporter 2, occurred at 12:09 a.m. EDT Thursday, Oct. 3.

Teams rolled the mobile launcher out to Kennedy’s Pad 39B in August 2023 for upgrades and a series of ground demonstration tests in preparation for NASA’s Artemis II mission. These preparations ranged from a launch day demonstration for the crew, closeout crew, and the pad rescue team, to testing the emergency egress system, water flow system, and the new liquid hydrogen sphere at the launch pad.

On its way to transport the mobile launcher back from the pad, NASA’s crawler-transporter 2 also achieved a milestone nearly 60 years in the making. Already designated by Guinness World Records as the heaviest self-powered vehicle – larger than a baseball infield and weighing approximately 6.65 million pounds – the crawler reached 2,500 miles traveled since its construction in 1965.

The mobile launcher is expected to arrive outside the Vehicle Assembly Building around 10 a.m. Thursday, Oct.3, before the Exploration Ground Systems teams move it into High Bay 3 on Friday, Oct.4.

Teams have joined the Artemis III European Service Module and crew module adapter for NASA’s Orion spacecraft inside the Neil A. Armstrong Operations and Checkout (O&C) Building at NASA’s Kennedy Space Center in Florida, following the completion of the Integration Readiness Review on Sept. 17.

The ESA (European Space Agency)-provided European Service Module is assembled by Airbus in Bremen, Germany, from parts made in 10 European countries and the United States. It acts as the driving force behind the Orion spacecraft for deep space exploration, providing essential propulsion, thermal control, and electrical power. The module also will supply astronauts with vital resources like water and oxygen, ensuring they’re well-supported during their journey to the Moon.

The crew module adapter bridges electrical, data, and fluid systems between Orion’s crew and service modules with an umbilical connector, and it also houses electronic equipment for communications, power, and control.

The integrated European Service Module and crew module adapter, which together make the service module, will undergo final inspections before engineers move it to the clean room inside the spaceport’s O&C high bay for welding operations. Later in the production flow, the Artemis III crew module will be connected to the service module via the crew module adapter.

The European Service Module is managed by the Orion team at NASA’s Glenn Research Center in Cleveland. The arrival of the Artemis III hardware to Kennedy marks the first time two Orion service modules have been inside the O&C facility at the same time during the agency’s Artemis campaign. The Artemis II service module is already mated to the crew module, and engineers continue to process the integrated modules inside the facility ahead of the test flight.

NASA to Fly International CubeSats Aboard Artemis II Test Flight

NASA is working to fly five CubeSats from international space agencies on the Artemis II test flight, the first crewed mission under NASA’s Artemis campaign.

In a ceremony at the German Space Agency DLR Sept. 18, Catherine Koerner, NASA’s associate administrator for exploration systems development, signed an agreement for Germany to fly TACHELES, a CubeSat that will collect measurements on the effects of the space environment on electrical components to inform technologies for lunar vehicles.

CubeSats are shoebox-sized payloads that have the potential to expand knowledge of the space environment. They will ride to space inside a ring that connects NASA’s Orion spacecraft to the upper stage of the SLS (Space Launch System) rocket. They will be deployed in high Earth orbit after the upper stage detaches from Orion and the spacecraft is safely flying free on its own and a safe distance away from the stage.

By working with other countries to fly CubeSats, NASA is increasing access to space for the international community and enabling its partners to expand scientific and technological knowledge. Although mission success for CubeSats historically has mixed results given their small size and the relatively low cost to develop them, the collaborations provide opportunities for NASA and other countries to work together to integrate and fly technology and experiments as part of Artemis.

NASA will share more details about the additional countries it is working with to fly CubeSats on Artemis II, all of which are countries that have signed the Artemis Accords, as the international agreements are put in place.
