Earth is the planet which the player starts on. Available activities at the Space Center include hiring more astronauts, building spacecraft, researching technology, and buying supplies from the market. There are also different buildings available.

Spaceships do not leave Earth under their own power, which would require prohibitive amounts of fuel. Instead, they automatically purchase a single-use booster rocket that helps them to clear Earth's gravity well. The first rocket for each spaceship is free, making this a non-issue as long as the player relies on single-use landers. For reusable landers, the cost of further rockets depends on the mass of the lander and the level of efficiency that the player has researched.

Reusable spacecraft that land on Earth automatically replenish their fuel and life support for free. However, repairing their durability is slower and requires purchasing hangar upgrades.
