Steel cable with a diameter of 1inch has a breaking strength of 47 tonnes. Give it a safety margin and assume it can hold 10 tonnes. So you need 10 cables per meter. So I assume in case the "lip" being just a sheet of steel it can be way thinner than 25mm.

- FeepingCreature 7y agoSure but you need to be sure that the thing you're attaching it to can hold the weight. Ie. if the martian floor was the ceiling, you'd have to be able to hang a plane off that attachment point without it ripping out. In other words, your lip needs to be distributing force onto a sufficient volume of ground to make up 100_000 metric tons of martian soil, per meter of circumference.
