Odysseus, the first US-built spacecraft to touchdown on the moon in more than half a century, is tipped over on its side, according to an update from Nasa and Intuitive Machines, the company that built and operated the lander.
The robotic lander descended on to the south polar region of the moon on Thursday at 6.23pm ET. But several minutes passed before flight controllers were able to pick up a signal from the lander’s communication systems.
As it landed, Odysseus “caught a foot in the surface and tipped” said Intuitive Machines CEO Steve Altemus, ending up on its side.
Still, the lander is “near or at our intended landing site”, he said. Nasa and Intuitive Machines said they have been receiving data from the lander and believe that most of the scientific instruments that it is carrying are in a position to work.

With the low gravity, you could install a reaction wheel to flip it and then stop when it’s upright.
Of course that adds complexity, and a high dynamic torque would need a more robust structure. Both of those things mean more weight and higher cost, both in construction and launch.
Just flip it again until it lands upright.
