Finding those canisters in planets is fun. But gathering them in your ship isnt.
Currently you can launch limpets but they get destroyed when they touch the canisters.
So my suggestion is simple. Make limpets work on planets with low enough gravity. With stronger gravity make them much slower.
But not to make things too easy, if you launch limpets when there are sentries left, they would shoot them. So you would still have to clear the area with your srv.
Nice addition would be able to call your ship from srv to launch those limpets.
