The Odysseus space probe’s stay on the lunar surface will be truncated, with projections that contact with the lander will cease today.
The landing happened just last week, marking a historic moment as the first privately financed lander to make contact with the moon, and the first US lander since 1972, made its nail-biting descent.
While Odysseus’s mission duration was expected to be a week to 10 days, the lander is shutting down operations a mere five days post-landing due to its unfortunate sideways position upon touchdown, which casts doubt on the amount of science data that may be unretrievable.
Intuitive Machines, the company that embarked on this mission alongside NASA, has acknowledged that skipping tests and human errors could have contributed to this early mission conclusion.
“We had opportunities to conduct tests and actually fire it,” said Intuitive Machines’ Mike Hansen, who leads the navigation systems team.
“But those tests would have been expensive and taken a significant amount of time.”
Before its descent near the moon’s south pole, a malfunction with the spacecraft’s laser-guided range finders triggered an unexpected additional orbit to allow controllers to devise a strategy for the improvised landing.
Just hours ahead of the landing, a problem arose when engineers failed to deactivate the laser safety switch pre-launch, a step that requires manual intervention.

Hansen, who developed the software “patch” to rectify the landing issues, noted that they haven’t yet established if the improvised navigational solution contributed to the spacecraft’s unanticipated landing angle.
On Friday, the organization reported that Odysseus caught one of its landing legs on an irregular lunar formation, causing it to tip and become somewhat supported by a rock.

Its solar panels faced limited sunlight as a result, and its antennas, directed towards the moon, impeded some communications.
The venture cost Intuitive Machines around $100m (£78m), with NASA contributing $118m (£93m).

FAQ – Odysseus Moon Mission Termination
- What was the Odysseus mission?
- The mission involved a lunar lander named Odysseus, developed by Intuitive Machines, in collaboration with NASA. It marked the first time a privately owned lander from the US touched down on the Moon since 1972.
- Why will the mission be cut short?
- The mission will be cut short because the lander inadvertently touched down on its side, reducing its ability to collect solar power and communicate effectively.
- What caused the sideways landing?
- Engineering errors, including a missed step to unlock a laser safety switch before launch and issues with the laser-guided range finders, led to an improvised landing strategy that might have contributed to the skewed touchdown.
- How long was Odysseus supposed to operate?
- It was planned for the lander to operate between a week and 10 days on the lunar surface.
- How much did the mission cost?
- Intuitive Machines invested around $100m (£78m) in the lander, with NASA providing an additional $118m (£93m).
Conclusion
The premature end of the Odysseus mission serves as a reminder of the complex challenges inherent in space exploration. Despite the significant achievements in landing the first privately owned American lander on the Moon in decades, technical oversights can greatly impact mission outcomes. As engineers and scientists assess the Odysseus mission, the lessons learned will undoubtedly contribute to future endeavors in lunar exploration and beyond.
