Leaving Earth

Base Game

General rules

  • Rocket parts which have not been consumed or destroyed can be later recovered unless they are in a space with the “!” symbol. Parts which are in Earth Orbit can be sent back to Earth for no Thrust cost (0). They have to successfully Land or Re-enter though.
  • Damaged parts which are in space can be repaired by a Mechanic by using 1 Supply, as long as they are currently part of his Spacecraft. All components are repaired by using 1 Supply. Damaged parts on Earth are automatically repaired at the end of the year.
  • If a player receives a part from another player (by attaching it to his Spacecraft, if the 2nd player agrees of course), he receives the Advancement for free, but the part has to be tested nevertheless as with any new Advancement. The tests done by the 2nd player do not count and are not mixed in any way.
  • Any Spacecraft (made of any parts) can be discarded by the owning player at any time.
  • Testing an Advancements applies to every other components that belongs to a player, also those that have already been sent to space in previous years. For example a Soyuz that is on Mars would be 100% safe to fire if the Soyuz Advancement is tested on Earth Orbit AFTER the older Soyuz has already reached Mars.
  • Ion Thrusters HAVE to be tested in space AND by doing a manoeuvre that requires 1 or more years (hourglass symbol). Note that some manoeuvres have optional hourglass symbols and can be used for testing closer to Earth.
  • Ion Thrusters and standard rockets can be mixed, though this can lead to a lot of extra math for longer trips.
  • Time tokens (hourglass) are removed at the BEGINNING of each year, not during or at the end.


  • Samples that have any type of value will give that amount to the player ONLY when returned to Earth and cannot be “cashed in” by any type of Astronauts.
  • If a mission is made impossible by conditions which are discovered on a planet, it is removed from the game and its points not counted.
  • Multiple missions can be completed with a single Spacecraft and with a single action.
  • A Sample that has been picked up by a Probe can be sent back to Earth without the Probe, in fact by the time it reaches Earth Orbit, the Sample could be the only part from which the Spacecraft is made.


  • To Survey Solar Radiation, execute a Survey action from anywhere beyond and including Earth Orbit. If not surveyed, the card is revealed the first time the hazard is faced (any path with the Radiation Hazard symbol, only affects astronauts in the base game, can affect spacecrafts too in the expansions).
  • A Survey mission can be completed by either completing a successful Survey action with a Probe from any space with the required planet’s Hazard symbol (usually fly-by, orbit or surface) OR by landing on the planet with ANY type of Spacecraft.


  • The Landing action on Earth and Venus is optional, as their atmosphere is dense enough to support parachutes (which are assumed to be present on every part). This is not the case on the Moon, which has no atmosphere and landing is mandatory for parts and Capsules. Mars has a thin atmosphere so it requires both, Landing for parts and Re-entry for Capsules.


  • Rendez-vous can be done with any parts beside Astronauts.
  • The Rendez-vous Advancement can only be tested in Earth Orbit and beyond, including on any planet surface. A Spacecraft can do so repeatedly, essentially researching the Advancement completely in one go.

Re-entry and Life Support

  • Re-entry is only required by capsules and/or other elements which transport people. The parts which can be damaged or destroyed on re-entry are the ones that mention it on the card, the others are not damaged. Everything else only needs a successful Landing.
  • Both Re-entry and Life Support can be tested by any Capsule, it doesn’t require Astronauts to be in it.
  • The Eagle Capsule doesn’t have a heat shield, which limits it to planets without an atmosphere (Moon, Mercury, Ceres).
  • When testing a Re-entry with a Spacecraft which is made of more than 1 Capsule and contains 1 or more Astronauts, the player ha to declare in which Capsule the Astronauts are before testing.


  • The Shuttle cannot use more than 1 fuel tank per manoeuvre.
  1. To Survey Solar Radiation, execute a Survey action from anywhere beyond and including Earth Orbit. If not surveyed, the card is revealed the first time the hazard is faced (any human is sent to Earth Orbit)

    I think the last part is wrong. The Hazard is faced (thus revealed of not already surveyed or “experienced”) when performing a manouvre that has the solar radiation symbol..so when the manned capsule LEAVES Earth Orbit to other destinations (other than landing back on the Earth)

    1. I looked it up and believe you are correct, you could SURVEY from EO but wouldn’t need to face the hazard. I will update the entry.
      I love how this game’s rules seem pretty straightforward at first, yet there seems to be an endless list of special case scenarios.
