Mars Lander - Puzzle discussion

well i tried a different way but doesn’t seems to be working, i write that if (v_speed <= -40) then v_speed = 4 but the thruster always seems to be on which confuse me

Would you please:
(a) specify which episode of Mars Lander you are working on?
(b) specify which test / validator you are working on?
(c) share a replay link? (Use the button called REPLAY AND SHARE at the bottom-right corner of the viewer.)

Bonjour, le lien vers le “calcul de vitesse” dans l’énoncé est mort.
