They forgot to put wheels on the Mars Phoenix

fucking $200,000,000 to build it and they couldn't spend $40 for tires from Wal-Mart?

Phoenix is a LANDER, not a ROVER. Nothing it's doing requires it to move around.

One of the future missions, though, will be able to fly to other research sites, enabling it to cover hundreds of kilometers as opposed to about 10km the current rovers cover over their lifetimes.
