Mars Mission was a Lego theme sold from 2007 to 2009. It is set on Mars and features astronauts, aliens, and high-tech machinery.


In the year 2045, a highly upgraded version of the Spirit, a previous Martian rover, was sent to the Red Planet, where it discovered mysterious, radio-active crystals (called 'Biodium' in the story). A crewed mission followed, which discovered intelligent life.

Pre-Hive Synopsis (2007)

Once arriving on the Red Planet, with vehicles designed for exploration and mining, the astronauts began mining the energy crystals abundant there. But soon, the crystals begin disappearing. It does not take the astronauts long to find the source of the problem: aliens sneakily making raids on their crystals. However, once discovered, the aliens become more open – and dangerous – about their thefts. The Astros quickly convert their vehicles into a hi-tech defense military force, and so, the war on Mars began. Later, the Astros at Eagle Command Base intercept a coded message from the aliens, saying they are not from Mars, but still intend to drive away the astronauts and claim the crystals for themselves. It was a harsh struggle for a long while, with both sides on a stalemate, until one of the Astro machines, named the Crystal Reaper, accidentally stumbled across the cracks forming the surface of the Alien Hive on Olympus Mons.

Hive Synopsis (2008)

Once awakened, the Hive, led by the ancient Alien Commander, led a strike force upon the teams of astronauts searching the mountain for energy crystals. There, the Battle of Olympus Mons began, with both Astros and Aliens taking heavy losses. An elite team of astronauts is sent into the hive to destroy it, and in the end, resulting in the destruction of the Hive. But the Alien Commander survives and retaliates by destroying the MX-81 Hypersonic Operations Aircraft.
