Mission Overview

IM-1 made history on February 22, 2024 when Intuitive Machines' Nova-C lander "Odysseus" touched down near Malapert A crater at the lunar south pole, becoming the first American spacecraft to land on the Moon since Apollo 17 in December 1972 — and the first privately built spacecraft ever to do so. The mission was part of NASA's Commercial Lunar Payload Services (CLPS) program.

The landing did not go entirely as planned. A last-minute discovery that the laser rangefinders were non-functional (their safety switch had not been removed before launch) forced engineers to improvise, using a NASA experimental lidar instrument (NDL) as a backup navigation sensor. Odysseus landed approximately 1.5 km from its target and tipped onto its side, coming to rest against a small crater rim.

Despite the tipped orientation, Odysseus successfully operated for about 7 days before its solar panels could no longer generate sufficient power. The lander transmitted data from all six NASA instruments and demonstrated that commercial companies could deliver payloads to the lunar surface — a key validation of the CLPS business model.

Mission Objectives

01

First Commercial Lunar Landing

Demonstrate that a private company can successfully deliver payloads to the lunar surface under NASA's CLPS program.

02

Deliver NASA Science Instruments

Transport and operate six NASA instruments including the Radio Frequency Mass Gauge, Laser Retroreflector Array, and Navigation Doppler Lidar.

03

Precision Landing Technology

Test the Nova-C's autonomous landing system and demonstrate precision targeting near the lunar south pole.

04

LOX/Methane Propulsion

Validate liquid oxygen / liquid methane propulsion for lunar landing — a propellant combination of growing interest for future missions.

05

Lunar South Pole Operations

Operate science instruments in the harsh south pole environment, demonstrating viability of this region for future exploration.

Outcome

Landed Successfully — Tipped on Side, Primary Objectives Met

Odysseus touched down near Malapert A crater on February 22, 2024, making Intuitive Machines the first private company to land a spacecraft on the Moon. However, the lander caught a foot on the surface and tipped onto its side, coming to rest against a small crater rim.

Despite the sideways orientation, Odysseus transmitted data from all six NASA instruments over approximately 7 days of surface operations before solar power became insufficient. The mission validated the CLPS model and proved commercial lunar delivery was achievable, though the navigation anomaly (disabled laser rangefinders) and tipping highlighted the challenges of precision lunar landing.

Spacecraft

Spacecraft diagram coming soon
01 Nova-C Lander Structure Hexagonal carbon fiber/aluminum structure standing 4 m tall. Six landing legs with energy-absorbing struts designed for soft landing on uneven terrain.
02 VR900 Engine Single 3D-printed main engine burning liquid oxygen and liquid methane (LOX/CH4). Throttleable for powered descent and landing.
03 Navigation System Designed to use laser rangefinders and an IMU for terrain-relative navigation. Backup NASA NDL (Navigation Doppler Lidar) was used after rangefinder failure.
04 Solar Panels and Power Body-mounted solar panels providing power during lunar day. Battery system for eclipse periods. Tipped orientation reduced power generation.
05 Payload Deck Mounting area for NASA instruments and commercial payloads, including EagleCam (deployable camera) and Columbia Sportswear insulation experiment.
