Lenny Loosejocks in Space/Jupiter

Jupiter is an asteroid field with most of the area consisting of the inside of one large asteroid. The planet has limited gravity so the jet pack is available and required to navigate.

To start off, head right into the large asteroid. Go up at the first junction. Once up, flip the lever to open the door ahead, then enter it. Carry on past the second lever past the flipping bridge to the third lever and flip it, it opens the door underneath.

With the third lever flipped, go back and flip the middle lever to clear the path and the left lever again, opening the lower door.

Return to the junction and take the lower path. If the first door is closed, go back and flip the left lever. If the second door is closed, go flip the lever above it. Continue along the floor to the rightmost path.

Towards the end of the rightmost path is another lever and closed door, just flip the lever to open the door forward. At the actual end of the path is another lever and flipping bridge. Flip the lever to move the bridge out of the way.

Return all the way back to the bottom junction and it's now a straight flight up to the bomb using the middle tunnel.

Disarming the bomb
It's another sliding block puzzle.

With the bomb defused, note down the digit that appears and fly all the way back to the ship.
