7644 MX-81 Hypersonic Operations Aircraft is a Mars Mission set released in 2008.


The MX-81 is one of the largest aircraft vehicles used by the Astronauts. Inside is a detailed lab which has an x-ray machine.In the lab you can also see two crystals which are used as "fuel" for the ship. Also included is an Alien vehicle and a small Astronaut mining vehicle. The drill on the mining vehicle rotates when the wheels are moved.You can land and reload it by releashing the platform on the back of the ship by pressing a button which is in front of the handle of the Hypersonic Operations Aircraft(HOA). Two patrol space crafts, a small one and one with more lasers, can be separated from the main vehicle. The HOA can also launch a missile and has a handle so one can play with it with ease. There is also a translusent orange capsule to store the captured Alien and a translusent yellowish green box with a "radioactive" sticker on it to store the energy crystals(you get a total of four in the set). Finally a small satellite can be detached

Three Astronauts, a glow-in-the-dark Alien, and Alien Commander minifigures are included.
