On Aug. 13, engineers and technicians inside the high bay of the Neil Armstrong Operations and Checkout Building at NASA’s Kennedy Space Center in Florida successfully completed a series of acoustic tests to ensure the Orion spacecraft for NASA’s Artemis II mission can withstand the speed and vibration it will experience during launch and throughout the 10-day mission around the Moon, the first Artemis mission with astronauts.

During the testing, engineers surrounded the crew module with large stacks of speakers, and attached microphones, accelerometers, and other equipment to measure the effects of different acoustic levels. Engineers and technicians will now analyze the data collected during the tests.

Prior to testing, the four Artemis II astronauts visited the high bay and viewed their ride to the Moon. With this test complete, technicians at Kennedy are on track to integrate Orion’s crew and service modules this fall.

NASA’s Moon Rocket Revealed Outside Vehicle Assembly Building

The rocket and spacecraft for NASA’s Artemis I mission has fully left Kennedy Space Center’s Vehicle Assembly Building (VAB) for the first time on the way to Launch Complex 39B for a wet dress rehearsal test.

The team is in a planned pause outside the building to retract the Crew Access Arm (CAA). The arm interfaces with the Orion spacecraft stacked atop the Space Launch System (SLS) rocket to provide access to the Orion crew module during operations in the VAB and at the launch pad. On crewed Artemis missions beginning with Artemis II, the access arm also will provide entry and exit for astronauts and payloads that will fly aboard. Several days before the rollout began, the arm was moved closer to the rocket to fit through the VAB door. Engineers are extending it to lock it in its travel position.

Once the CAA retraction is complete, the team will continue the four-mile trek to Launch Complex 39B.

The Space Launch System rocket and Orion spacecraft for the Artemis I mission are rolling to Launch Complex 39B at the Kennedy Space Center in Florida for the very first time. At about 5:45 p.m. ET, with the integrated SLS and Orion system atop it, the crawler-transporter began the approximately 4-mile, journey from the Vehicle Assembly Building (VAB) to the launch pad. Once outside the VAB high-bay doors, the Moon rocket will make a planned pause allowing the team to reposition the Crew Access Arm before continuing to the launch pad. The crawler-transporter will move slowly during the trek to the pad with a top cruising speed of .82 mph. The journey is expected to take between six and 12 hours.

After they arrive at the pad, engineers will prepare the integrated rocket and Orion spacecraft for a critical wet dress rehearsal test that includes loading all the propellants

Earlier today, engineers and technicians at NASA’s Kennedy Space Center in Florida drove Crawler Transporter-2, which will carry NASA’s Moon rocket to the launch pad, to the doors of the Vehicle Assembly Building (VAB). Soon, the 6.6-million-pound crawler will go inside the VAB and slide under the Space Launch System rocket and Orion spacecraft placed on the Mobile Launcher. Technicians will finish up preparations to transport the rocket traveling at a top speed of 1 mph to Launch Complex 39B for a wet dress rehearsal test ahead of the Artemis I launch.

This week, the Kennedy team also completed painting the NASA worm logo on the Space Launch System solid rocket boosters. While painters added parts of the iconic logo before the segments were stacked, they had to wait until the boosters were fully assembled to finish the job.

In addition, the team has continued to retract the 20 platforms that surround the Space Launch System rocket and Orion spacecraft ahead of rollout on March 17 for the wet dress rehearsal test. The wet dress rehearsal will be the final major test for the Artemis I mission and will ensure the rocket, spacecraft, ground equipment and launch team are “go” for launch.

Progress on Testing and Instrumentation Installation Ahead of Artemis I Launch

Work continues inside the Vehicle Assembly Building (VAB) at NASA’s Kennedy Space Center in Florida in preparation for the Artemis I wet dress rehearsal test, currently targeted for next month. Teams have been installing the flight termination system on the rocket and working on the first of a two-part test of the system. For safety, all rockets are required to have a flight termination system that the Space Launch Delta 45 can use to terminate the flight if necessary. Once the rocket and spacecraft systems are verified during wet dress rehearsal testing, the 322-foot-tall rocket will roll back into the VAB for final inspections and checkouts, including the second part of the flight termination system test, ahead of returning to the pad for launch.

In addition to work on the flight termination system, the team is installing instrumentation on the twin solid rocket boosters and core stage, as well as instrumentation needed for the wet dress rehearsal rollout. Artemis I is a flight test, and engineers will capture as much data as possible on the performance of all the systems that are part of the Space Launch System (SLS) rocket and the Orion spacecraft as well as the Kennedy ground systems that support the vehicle during rollout, wet dress rehearsal, and launch. Not only will this be the first integrated flight for SLS and Orion, but it will be the first use of many new ground systems. Thousands of sensors and special instruments will monitor the rocket and spacecraft as they make the four-mile journey to Launch Complex 39B next month. The team is also working to inspect and install thermal blankets on the core stage engine section.

Up next, the team plans to power up the Orion spacecraft as part of testing the flight termination system and then close the spacecraft’s hatch after powering it down.

Artemis I Countdown Test Complete

Artemis I chart of test and checkout milestones Engineers and technicians successfully completed a second countdown sequencing test on Jan. 24 inside the Vehicle Assembly Building at NASA’s Kennedy Space Center in Florida. This is one of the final tests for the SLS rocket and Orion spacecraft ahead the Artemis I mission, and brings the team one step closer to rolling to the launch pad in mid-February for the wet dress rehearsal test.

The test demonstrated the ground launch software and ground launch sequencer, which checks the health and status of the rocket sitting on the pad. The simulated launch countdown tested the responses from the Space Launch System rocket and Orion spacecraft, ensuring the sequencer operates correctly. On launch day, the ground launch sequencer hands off to the rocket and spacecraft, and an automated launch sequencer takes over control of the rocket from ground controllers around 30 seconds before launch.

Up next the team will work to complete the final program specific engineering tests for the Artemis I mission. With the countdown sequencing test complete, Exploration Ground Systems teams will continue doing final checks and closeouts of the Moon rocket in preparation for the wet dress rehearsal test next month. For wet dress rehearsal, engineers will fully load SLS with propellant, and the team on the ground will run through all the pre-launch operations to prepare for the Artemis I launch.

Artemis I Integrated Testing Continues Inside Vehicle Assembly Building

On Dec. 17, the team completed a communications end-to-end test to ensure the rocket, spacecraft and ground equipment can communicate with the consoles in the launch and mission control centers. This verification of communication systems via radio frequency ensures the launch team will be able to monitor the Space Launch System (SLS) rocket and Orion spacecraft on the ground as well as during flight. The test used an antenna in the VAB, another near the pad that will cover the first few seconds of launch, as well as a more powerful antenna that uses the Tracking Data Relay Satellite and the Deep Space Network.

On Dec. 20, the Exploration Ground Systems team conducted a countdown sequencing test to demonstrate the ground launch software and ground launch sequencer, which checks for health and status of the vehicle sitting on the pad. The simulated launch countdown tested the responses from SLS and Orion, ensuring the sequencer can run without any issues. On launch day, the ground launch sequencer hands off to the rocket and spacecraft and an automated launch sequencer takes over around 30 seconds before launch. Engineers have added a second sequencing test before rollout to account for differences between the emulator and flight hardware identified during the initial test.

Last week engineers and technicians successfully removed and replaced an engine controller from one of four RS-25 engines after the team identified an issue during a power-up test of the rocket’s core stage. Engineers are now performing standard engine controller diagnostic tests and check-outs, including controller power-up and flight software load. Subsequently, the team will work to complete all remaining SLS pre-flight diagnostic tests and hardware closeouts in advance of a mid-February rollout for a wet dress rehearsal in late February. NASA will set a target launch date after a successful wet dress rehearsal test.

SLS will be the most powerful rocket in the world and is the only rocket that can send Orion, astronauts, and supplies to the Moon in a single mission. With the Artemis missions, NASA will land the first woman and the first person of color on the Moon and establish long-term exploration in preparation for missions to Mars. SLS and Orion, along with the commercial human landing system and the Gateway that will orbit the Moon, are NASA’s backbone for deep space exploration.

Orion Spacecraft Goes ‘Shields Up’ for Artemis I

Teams at NASA’s Kennedy Space Center in Florida are putting the final touches on the Orion spacecraft for the Artemis I mission by connecting the ogive fairings for the launch abort system (LAS) assembly. Pronounced oh-jive, the ogive fairings consist of four protective panels, and their installation will complete the LAS assembly.

Technicians and engineers from the center’s Exploration Ground Systems and contractor Jacobs recently finished attaching the launch abort tower to the top of the Orion crew module. They then began lifting and mating the lightweight fairings, which will shield the crew module from the severe vibrations and sounds it will experience during launch. One of the fairing panels has a hatch to allow access to the crew module before launch.

During Artemis missions, the 44-foot-tall LAS will detach from the spacecraft when it is no longer needed, shortly after launching on the Space Launch System (SLS) rocket, to lighten the journey to the Moon. Although the abort motors will not be active on the uncrewed Artemis I flight test, the system is intended to protect astronauts on future missions if a problem arises during launch or ascent by pulling the spacecraft away from a failing rocket.

Once LAS installation is complete, the spacecraft will leave the Launch Abort System Facility and continue on its path to the pad, making its way to the spaceport’s Vehicle Assembly Building to be integrated with the SLS rocket ahead of the launch.

Fueling Underway For Artemis I Launch

Teams with NASA’s Kennedy Space Center Exploration Ground Systems and primary contractor, Jacobs, are fueling the Orion service module ahead of the Artemis I mission. The spacecraft currently resides in Kennedy’s Multi-Payload Processing Facility alongside the Interim Cryogenic Propulsion System (ICPS), the rocket’s upper stage that will send Orion to the Moon. After servicing, these elements will be integrated with the flight components of the Space Launch System, which are being assembled in the Vehicle Assembly Building.

Technicians began loading Orion’s service module with oxidizer, which will power the Orbital Maneuvering System main engine and auxiliary thrusters on the European-built service module ahead of propellant loading. These auxiliary thrusters stabilize and control the rotation of the spacecraft after it separates from the ICPS. Once the service module is loaded, teams will fuel the crew module to support thermal control of the internal avionics and the reaction control system. These 12 thrusters steady the crew module and control its rotation after separation from the service module.

Once Orion servicing is complete, teams will fill the ICPS. This liquid oxygen/liquid hydrogen-based system will push the spacecraft beyond the Moon for the test flight under the agency’s Artemis program. In several weeks, when fueling is complete, Orion will move to the center’s Launch Abort System Facility to integrate its launch abort system, and the ICPS will move to the Vehicle Assembly Building to be stacked atop the mobile launcher.

The Space Launch System (SLS) rocket’s interim cryogenic propulsion stage (ICPS) moved into the Multi-Payload Processing Facility February 18, 2021, at NASA’s Kennedy Space Center in Florida alongside one of its flight partners for the Artemis I mission, the Orion spacecraft. Both pieces of hardware will undergo fueling and servicing in the facility ahead of launch by teams from NASA’s Exploration Ground Systems and their primary contractor, Jacobs Technology. The rocket stage and Orion will remain close during their journey to space.

Built by United Launch Alliance and Boeing, the ICPS will be positioned above the core stage and will provide the power needed to give Orion the big push it needs to break out of Earth orbit on a precise trajectory toward the Moon during Artemis I.

This is the first time since the shuttle program that two pieces of flight hardware have been processed inside this facility at the same time. Once final checkouts are complete, the ICPS and Orion will part ways on the ground and be reunited in the Vehicle Assembly Building for integration onto the SLS rocket.

Artemis I will be an integrated flight test of the SLS rocket and Orion spacecraft ahead of the crewed flights to the Moon. Under the Artemis program, NASA will land the first woman and the next man on the lunar surface and establish a sustainable presence at the Moon to prepare for human missions to Mars.
