"In this set, a technician and an astronaut are evaluating a potential Mars Rover to carry people around on the Red Planet. If you liked the movie "The Martian," this set harkens to those scenes of the rover saving the astronaut. Only drawback is that you have to remove the entire canopy to put the astronaut inside, and it only fits one person. What you see is what you get - essential transportation on Mars."
"Guessing here, but I think the "story" behind this set is that astronauts in orbit around Mars in a space shuttle are controlling a Mars drone and robotic exploration rover on the surface, then a rocket box (?) lofts a rock sample up to the ship for study. You get a little of everything, here: a shuttle, two astronauts, a six-wheeled rover, flying drone, rocks, and return box. If you're looking for a Lego "sampler" of the new City Mars Exploration set, this is probably it. Two gripes: the landing gear is too small for a shuttle this size, and the shuttle "cargo bay" will only fit the astronaut and a box, not a satellite or anything larger. The shuttle would not be able to land on Mars unless astronauts on the surface build a runway! Still, I think there's good play value and parts value here and if you can't swing the price of the whole series, this is the one to get for your budding astronaut."
"Good look, good dollar value, good play value! Four little gripes/suggestions: 1) the satellite doesn't positively lock into the satellite bay (it kinda flops around in there--no good for re-entry!) 2) a fellow astronaut won't fit in the satellite bay if he needs to be rescued 3) No landing gear, 4) Decals with optional numbers should have been included, because we're going to want a little fleet of these."
"This set is larger than it looks on the box, and will make a decent display piece. Only advanced builders should attempt it, though, due to the "fiddliness" of the assembly. I was disappointed in the astronauts. Lego went to the trouble of making a finely printed, realistic torso...then covered it up with a one-piece deep sea diver helmet/ oxygen tank/ chestplate from the Atlantis sets. They just don't look right. This set deserved a more realistic helmet and separate, printed backpack with the American flag. Construction was very fiddly at times - mostly due to extremely tight fits between pieces, and the exasperating leg assemblies. I think parts were taken out of the attach point for the legs on the descent stage to get the price under $100; there's not really enough to firmly hold it all firmly together. I suggest putting the descent stage on a Lego pick-a-brick cup to work on the dangling legs without having to set the whole thing on a table to flop around and fall apart. Ignore the picture on the box: the ascent stage attitude thrusters should (and can be!) oriented over the deflectors on the lower half. The designer was right; the photographer was wrong. The windows are a real departure from the look of the actual ship. Maybe next time Lego can do better there. Overall, a decent replica, but everyone will instantly recognize it as Lego, unlike the Saturn 5, which was a perfect 5 out of 5. My advice to Lego - next time, spend a little extra to get those little nice touches. They make or break a model like this."
