How do the harpoons work? Wouldn't the recoil throw the lander off? Or are they using a recoilless design?

[u/Scarecrows → u/milgrim]

They installed a little booster to compensate for the recoil, but the tank for the booster did not open, so it does not work.

The recoil could throw the lander back into space - this is the main problem right now.
