Some suggestions... (I know, some are too long. But, who knows, it might to get ideas)

- éperoner, choc, percer :RAM / RAMMING / RAM CAPABLE
- repli, retraite, fuite (fuire), rentrer : GO BACK (when encountering a black hole; "retour"? "annuler"?)
- rentrer, retrait (?), repos, maison, retour : RETIRE (button is tight)
- Hop (?), marche, -U-, : USE (button on cargo objects; button is very short)
