Must be the coolest set of Mars Mission — “This massive track vehicle features three astronauts, two green aliens and one alien commander. The build is manageable, even if you were an unexperienced LEGO builder. Another bonus to this set is, that you can combine it with a LEGO Technic Power Functions set and a... More Technic Remote Control. It looks super cool, has a lot of details and functions and can even be turned into a remote operated vehicle”

“This mining vehicle is solid, compact, and well-designed. It looks impressive, and even better, it has fantastic Power Functions operability! Behold 7645 - MT-61 Crystal Reaper. The best part of this set - and the reason I bought it, really - is the integration of Power... More Functions. Bizarrely this isn't mentioned at all on the box and I only found out about it from the instructions. This is a great set made even better with the addition of Power Functions.”

About Space Mars Mission

Mars Mission was a LEGO Space subtheme released in 2007 that consisted of 17 sets whose story focused on the adventures of a team of Astronauts as they land on Mars and are forced to contend with a dangerous alien race. The humans are a group of astronauts that have journeyed to Mars in search of powerful yellow-green energy crystals found on the Martian surface to power their futuristic devices and technology. The Aliens have originated from an unknown place in the cosmos, and are also searching for the crystals as well. Both races wish to use these crystals as power sources, which can be used to supply energy to all of their respective vehicles and systems and as such they fought each other.

Mars Mission consists of 17 sets that ran from 2007 to 2008. As of today, 7649 MT-201 Ultra-Drill Walker is the most valuable Mars Mission set with an estimated new/factory sealed value of $599.
