Why It’s So Challenging to Land Upright on the Moon

Two spacecraft have ended up askew on the lunar surface this year. It is easier to tip over in the weaker gravity on the moon than you may imagine.
See the Odysseus lander on the moon’s surface, shown at a tilt.
The "tilted Odysseus lander on the moon" is one of the last images it transmitted before shutting down on Thursday.
When the robotic lander Odysseus last month became the first American-built spacecraft to touch down on the moon in more than 50 years, it toppled over at an angle. That limited the amount of science it could do at the lunar surface, because its antennas and solar panels were not pointed in the correct directions.
Just a month earlier, another spacecraft, the Smart Lander for Investigating Moon, or SLIM, sent by the Japanese space agency, had also tipped during landing, ending up on its head.
Why is there a sudden epidemic of spacecraft rolling on the moon like Olympic gymnasts performing floor routines? Is it really that difficult to land upright there?
On the internet and elsewhere, people pointed to the height of the Odysseus lander — 14 feet from the bottom of the landing feet to the solar arrays at the top — as a contributing factor for its off-kilter touchdown.
