Rocket

Notes Can travel to other planets, land on grass
Rockets are kind of a gimmick Vehicle, but one that's vital to completing the game. Like the Plane, you need two Items to use a Rocket—an Ankh to Board and a Tri-Lithium to Launch. However, unlike other Vehicles, the Tri-Lithium is consumed each time you do this, as well as each time you Hyper Jump. You'll need a minimum of four for a round trip to another planet. Be careful when taking longer trips, because every time you use a Tri-Lithium when your current total ends in 4 or 8, you end up off course.

Landing on a planet is dangerous, because if you try to land on any terrain except grass, you die. You can't save while on other planets, so dying on your return to Earth can be especially disheartening.

You can only buy a single Shuttle, and it doesn't move, so don't forget which city you bought it in. It's best to buy it in a city you use as a central base of operations. Launching it will send you to space, and when you land it will return to its launch point. Be aware that you can't safely dock in space unless you're wearing a Vacuum suit or a Reflect suit.
