Take On Mars accessible. The speed of the rovers is increased along with their instruments. Unlike actual Mars exploration vehicles, the in-game spacecraft are controlled in real time: rather than planning a Martian spacecraft's tasks for the day, the player directly operates its instruments. Functions that a user must perform include driving to new destinations, imaging terrain, and collecting samples. Multiple science instruments are unlocked by the player in order to study Mars and complete mission objectives. Many landings are required to complete all missions for any given location. Each spacecraft carries a relevant suite of instruments designed to complete its assigned objectives.
