8.5 months ago, NASA shot about 4 metric tons of high precision milled metal and fuel out of the atmosphere. In 4 days, it will strike it's target, the red planet. That'll show those motherfuckers who is the boss in this solar system.
However, there is a small chance that a frankly crazy landing procedure will actually work and deliver a 1 ton rover to the surface.
Not to worry though, they've equipped it with a rock vaporizing laser and a drill so we're not completely defenseless against whatever is down there producing methane gas.
Unlike previous rovers, this one is running on nuclear power, which will deliver some extra torque for those steep martian slopes. Also, it won't be bothered by stuff like dust or martian winter.
I for one can't wait to see nerds high fiving each other in the control room, and a new batch of desktop wallpapers.
