Shuttles are specialized transports that ferry people and cargo between trade stations and planets. They Void Catapult into orbit, exchange cargo on a trade station, and then glide gracefully back to the planet.
Since a major role is to move people between planets and stations, shuttles tend to be more elegant than other cargo ships such as interstellar freighters.
Why not Catapult back down?
Void Catapults have a wide margin of error, while catapulting in space is relatively safe, it’s best to avoid popping out near any large physical matter such as the surface of a planet. In addition, emerging from Void into atmosphere takes a heavy toll on ships.
