NASA – Artemis

Rocket Hardware for Future Artemis Flights Moved to Barge for Delivery to NASA’s Kennedy Space Center

NASA is making strides with the Artemis campaign as key components for the SLS (Space Launch System) rocket continue to make their way to NASA’s Kennedy Space Center in Florida. Teams with NASA and Boeing loaded the core stage boat-tail for Artemis III and the core stage engine section for Artemis IV onto the agency’s Pegasus barge at Michoud Assembly Facility in New Orleans on Aug. 28.

The core stage hardware joins the launch vehicle stage adapter for Artemis II, which was moved onto the barge at NASA’s Marshall Space Flight Center in Huntsville, Alabama, on Aug. 21. Pegasus will ferry the multi-mission rocket hardware more than 900 miles to the Space Coast of Florida. Teams with the NASA’s Exploration Ground Systems Program will prepare the launch vehicle stage adapter for Artemis II stacking operations inside the Vehicle Assembly Building, while the core stage hardware will be moved to Kennedy’s Space Systems Processing Facility for outfitting. Beginning with Artemis III, core stages will undergo final assembly at Kennedy.

The launch vehicle stage adapter is essential for connecting the rocket’s core stage to the upper stage. It also shields sensitive avionics and electrical components in the rocket’s interim cryogenic propulsion stage from the intense vibrations and noise of launch.

The boat-tail and engine section are crucial for the rocket’s functionality. The boat-tail extends from the engine section, fitting snugly to protect the rocket’s engines during launch. The engine section itself houses more than 500 sensors, 18 miles of cables, and key systems for fuel management and engine control, all packed into the bottom of the towering 212-foot core stage.

NASA is working to land the first woman, first person of color, and its first international partner astronaut on the Moon under Artemis. SLS is part of NASA’s backbone for deep space exploration, along with the Orion spacecraft, supporting ground systems, advanced spacesuits and rovers, the Gateway in orbit around the Moon, and commercial human landing systems. SLS is the only rocket that can send Orion, astronauts, and supplies to the Moon in a single launch.

NASA’s SLS (Space Launch System) rocket core stage for the Artemis II mission is inside the Vehicle Assembly Building at the agency’s Kennedy Space Center in Florida.

Tugboats and towing vessels moved the barge and core stage 900-miles to the Florida spaceport from NASA’s Michoud Assembly Facility in New Orleans, where it was manufactured and assembled.

Team members with NASA’s Exploration Ground Systems Program safely transferred the 212-foot-tall core stage from the agency’s Pegasus barge, which arrived at NASA Kennedy’s Complex 39 turn basin wharf on July 23, onto the self-propelled module transporter, which is used to move large elements of hardware. It was then rolled to the Vehicle Assembly Building transfer aisle where teams will process it until it is ready for rocket stacking operations.

In the coming months, teams will integrate the rocket core stage atop the mobile launcher with the additional Artemis II flight hardware, including the twin solid rocket boosters, launch vehicle stage adapter, and the Orion spacecraft.

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 powerful SLS (Space Launch System) rocket core stage for the Artemis II mission arrived on Tuesday, July 23, at the agency’s Kennedy Space Center in Florida. The core stage will help power SLS when it launches four astronauts around the Moon for the first crewed flight of SLS and the Orion spacecraft during the Artemis II test flight.

The core stage, aboard NASA’s Pegasus barge, traveled from the agency’s Michoud Assembly Facility in New Orleans and spent seven days coasting through the Gulf of Mexico and then the Atlantic Ocean before arriving at NASA Kennedy’s Complex 39 turn basin wharf.

The 212-foot-tall SLS core stage, its propellant tanks, avionics, flight computer systems, and four RS-25 engines, were manufactured and assembled at NASA Michoud. Now, teams with NASA Kennedy’s Exploration Ground Systems Program will prepare the rocket stage for integration ahead of launch.

The only rocket that can send the Orion spacecraft, astronauts, and supplies to the Moon on a single launch is the Space Launch System. Its core stage provides more than two million pounds of thrust and the whole rocket provides 8.8 million pounds of thrust to launch Artemis II to the Moon.

Up next, the core stage will roll to NASA Kennedy’s Vehicle Assembly Building, where teams will process it until it is ready for rocket stacking operations.

Follow the livestream of the core stage offload online expected to begin at 9 a.m. Wednesday.

NASA’s Artemis II Orion Spacecraft Prepares for Vacuum Testing

The Artemis II Orion spacecraft is pictured surrounded by the metal walls of the altitude chamber — Technicians used a 30-ton crane to lift NASA’s Orion spacecraft on Friday, June 28, 2024, from the Final Assembly and System Testing (FAST) cell to the altitude chamber inside the Neil A. Armstrong Operations and Checkout building at NASA’s Kennedy Space Center in Florida. The spacecraft, which will be used for the Artemis II mission to orbit the Moon, underwent leak checks and end-to-end performance verification of the vehicle’s subsystems.

NASA’s Orion spacecraft for the Artemis II mission was lifted out of the Final Assembly and System Testing cell on June 28 inside the Neil A. Armstrong Operations and Checkout building at NASA’s Kennedy Space Center in Florida. The integrated spacecraft has been undergoing final rounds of testing and assembly, including end-to-end performance verification of its subsystems and checking for leaks in its propulsion systems.

A 30-ton crane returned Orion into the recently renovated altitude chamber where it underwent electromagnetic testing. The spacecraft now will undergo a series of vacuum chamber qualification testing. The tests will subject the spacecraft to a near-vacuum environment by removing air, thus creating a space where the pressure is extremely low. This results in no atmosphere, similar to the one the spacecraft will experience during future lunar missions.

Testing will span approximately a week, with technicians collecting data from the spacecraft’s chamber, cabin, and the environmental control and life support system to test spacesuit functionality. The data recorded during these tests will be used to qualify the spacecraft to safely fly the Artemis II astronauts through the harsh environment of space.

On Friday, April 26, engineers completed a series of electromagnetic tests on the integrated Orion crew and service module for NASA’s Artemis II mission inside the Neil A. Armstrong Operations and Checkout (O&C) Building at the agency’s Kennedy Space Center in Florida.

During testing, engineers subjected the spacecraft to electromagnetic energy using wave guides, amplifiers, and antenna horns while inside an altitude chamber.

The test helps verify that all of Orion’s electronic systems can work in sync and safeguards against potential malfunctions caused by electromagnetic disturbances in the harsh and complex environment of space. Engineers will analyze the data collected during testing to ensure all systems on Orion are not disturbed by electromagnetic energy and the spacecraft is ready to safely fly the crew around the Moon.

The team returned the spacecraft to the Final Assembly and System Testing, or FAST cell inside the O&C building following electromagnetic testing for additional work in preparation for further performance testing inside the vacuum chamber later this summer.

NASA and Intuitive Machines co-hosted a news conference on Feb. 28 to provide a status update on the six NASA instruments that collected data on the IM-1 mission.

Mission challenges and successes were discussed during the briefing including more than 350 megabits of science data downloaded ready for analysis. During transit, all powered NASA payloads operated and received data. During descent and landing, guidance and navigation data was collected that will help improve landing precision in the future, and all three payloads that were designed to operate on the surface have received data.

The first images from the lunar surface are now available and showcase the orientation of the lander along with a view of the South Pole region on the Moon. Intuitive Machines believes the two actions captured in one of their images enabled Odysseus to gently lean into the lunar surface, preserving the ability to return scientific data. After successfully transmitting the image to Earth, there is additional insight into Odysseus’ position on the lunar surface.

On Feb. 22, NASA science instruments and technology on board Intuitive Machines’ Nova-C lander, called Odysseus, landed on the Moon’s South Pole region, marking the United States’ first return since Apollo 17. This was also the first landing as part of the agency’s CLPS (Commercial Lunar Payload Services) initiative — transmitting valuable science data of each NASA payload from the lunar surface.

Additional updates can be found by watching the news conference here.

NASA Science Touches Down on Moon with Intuitive Machines’ Mission

Carrying NASA science and technology to the Moon, Intuitive Machines’ uncrewed lunar lander touched down at 5:23 p.m. CST on Thursday. The instruments aboard Odysseus will prepare NASA for future human exploration of the Moon under Artemis. Additional updates will be available Friday, Feb. 23.

Intuitive Machines Prepares to Land on the Moon with NASA Science Ready to Begin Operations

After a successful lunar orbit insertion, Odysseus is currently orbiting the Moon, approximately 12 miles above the lunar surface. Carrying six NASA science investigations and technology demonstrations, the Intuitive Machines lander is expected to land at 6:24 p.m. EST near Malapert A in the south polar region of the Moon. Watch now on NASA+, NASA TV, and the agency’s website.

Over the last seven days as the mission has travelled from the Earth to the Moon, all powered NASA science instruments have completed their transit checkouts, collected data, and are operating as expected. Flight controllers will continue to analyze the data collected and monitor the payloads to inform preparations for landing.

The remaining lunar descent milestones include the following. All times are approximate:

Time (EST)	Event
6:11 p.m.	Powered Descent Initiation
6:22 p.m.	Pitch Over with Main Engine
6:23 p.m.	Hazard Detection and Avoidance
6:24 p.m.	Vertical Descent
6:24 p.m.	Terminal Descent
6:24 p.m.	Landing

Intuitive Machines Updates IM-1 Mission Landing Time

NASA science is taking another orbit around the Moon. Flight controllers chose to complete an additional orbit before beginning the IM-1 Mission landing sequence. The updated landing time is 6:24 pm. EST.

NASA coverage of the mission will begin at 5 p.m. on NASA+, NASA TV, and the agency’s website.

Intuitive Machines’ Odysseus lander has completed lunar orbit insertion successfully and is currently orbiting the Moon. Odysseus continues to be in excellent health and is approximately 60 miles (92km) from the Moon.

The spacecraft will orbit the Moon for approximately one day before beginning its descent toward the lunar surface. The landing opportunity is targeted for Thursday, Feb. 22, at 5:30 p.m. EST.

All powered NASA science instruments on board have completed their transit checkouts, received data, and are operating as expected, including: LN-1 (Lunar Node 1 Navigation Demonstrator), NDL (Navigation Doppler Lidar for Precise Velocity and Range Sensing), RFMG (Radio Frequency Mass Gauge), ROLSES (Radio-wave Observations at the Lunar Surface of the Photoelectron Sheath), SCALPSS (Stereo Cameras for Lunar Plume-Surface Studies). Since the LRA (Laser Retroreflector Array) instrument is a passive experiment designed for the lunar surface, it cannot conduct any operations in transit.

LN-1 has made three successful passes with NASA’s Deep Space Network, establishing real-time communications with ground stations on Earth. Upon lunar touchdown, the LN-1 team will conduct a full systems checkout and begin continuous operations within 24 hours of landing. NASA’s Deep Space Network will receive its transmissions, capturing telemetry, Doppler tracking, and other data and relaying it back to Earth.

A SCALPSS checkout was completed during transit, confirming the cameras are operating as expected and the instrument is in good health. Using four tiny cameras, SCALPSS will collect imagery of how the surface changes from interactions with the spacecraft’s engine plume as the lander descends toward the Moon.

RFMG continues to gauge the cryogenic propellants on Odysseus throughout the mission, including propellant loading, transit, lunar orbit insertion burn, and low lunar orbit. Data collection and analysis will continue through landing on the Moon and could provide insights on how to measure fuel in microgravity.

NDL and ROLSES have been operated, and flight controllers will continue to monitor the instruments and collect data to inform preparations for landing.
