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.
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:
|Powered Descent Initiation
|Pitch Over with Main Engine
|Hazard Detection and Avoidance
Carrying NASA science instruments to the Moon, Intuitive Machines’ flight controllers conducted a lunar correction maneuver to raise the orbit for Odysseus overnight. As a result, the anticipated landing time is now 4:24 p.m. EST on Thursday, Feb. 22.
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.
Intuitive Machines’ IM-1 mission is the company’s first mission through the agency’s Commercial Lunar Payload Services initiative, which aims to gain new insights into the lunar environment and expand the lunar economy to support future crewed missions under NASA’s Artemis campaign.

After a successful launch on Feb. 15, six NASA science instruments and technology demonstrations continue their journey to the Moon aboard Intuitive Machines’ lander named Odysseus. The company confirmed communications contact with its mission operations control in Houston, and its lander continues to perform as expected.
Known as IM-1, Intuitive Machines successfully transmitted its first images back to Earth on Feb. 16. These were captured shortly after separation from SpaceX’s second stage, on Intuitive Machines’ first journey to the Moon as part of the agency’s Commercial Lunar Payload Services initiative and Artemis campaign.
Within an hour of launching, NASA confirmed data was streaming from the agency’s powered science and technology instruments aboard the flight. This means data from these instruments was automatically streaming back to the teams so NASA could monitor the health and status of its instruments.
Later, Intuitive Machines successfully commissioned Odysseus’ engine which means they exercised the engine’s complete flight profile, including the throttling required for landing. The engine, which uses liquid methane and liquid oxygen, is the first of its kind fired in space.
One of the NASA instruments, the Radio Frequency Mass Gauge is gauging the cryogenic propellants on Odysseus throughout the mission. Data files have been collected and many have been downloaded for analysis. Throughout the propellant loading phase that took place before launch, the instrument collected data, which was downloaded and analyzed in near-real time. Data also is being collected during the microgravity transit phase of the mission. This analysis will continue through landing on the Moon.
Another NASA instrument, Lunar Node 1 Navigation Demonstrator, integrates navigation and communication functionality. This science instrument will operate for the first time today and daily during the cruise phase as the landing date draws closer. The radio beacon is designed to support precise geolocation and navigation observations to orbiters, landers, and surface personnel, digitally confirming their positions on the Moon relative to other craft, ground stations, or rovers on the move. The check-out helps prepare to land on the Moon as the navigation demonstrator aims to gather this data throughout the duration of the surface operations phase of the mission. Over the next day, flight controllers will analyze the data from this procedure to inform preparations for landing on Thursday, Feb. 22.

Intuitive Machines’ Nova-C lander successfully powered on, made communications contact, and is now on its way to the Moon, carrying NASA science and technology demonstrations as part of the agency’s CLPS (Commercial Lunar Payload Services) initiative and Artemis campaign.
Nova-C is expected to land on the lunar surface Thursday, Feb. 22, and throughout its mission, the agency’s scientific instruments will focus on plume-surface interactions, space weather/lunar surface interactions, radio astronomy, precision landing technologies, and a communication and navigation node for future autonomous navigation technologies.
This concludes our live launch coverage. Continue to follow along for more CLPS updates: nasa.gov/clps.
