Space Race: Asteroid Track

Welcome to space! In Space Race, you'll try to get around an asteroid in as few turns as possible.
Here in space, motion works a little bit differently. You can't just choose where you want to go and then go there: you've got all of your past movement and momentum to deal with.
Choose your ship and control its thrusters. To navigate, swipe up, down, left, or right to change your momentum by one square. For example: if the last turn you went two squares up and one square right, and then this turn you swiped down, you'd go one square up and one square right. You went your movement from last turn (two up, one right), and then went one square in the direction you swiped (one down), for a total of (one up, one right).
Your goal is to get around the asteroid in as few turns as you can. Be warned: it’s easy to speed up, but hard to avoid crashing into the asteroid or the walls. Good luck!
