NASA preps for ‘7 minutes of terror’ on Mars
[T]hey have to get the lander on the ground, and that’s where the worry comes in. In fact, they have a name for it in the Mars exploration community: “seven minutes of terror.”
Seven minutes is all it takes for a spacecraft travelling neary 13,000 miles per hour to hit the Martian atmosphere, slam on the brakes and reach the ground.
And then there’s this tidbit, with the resulting obligatory snark:
Historically, 55 percent of Mars missions have ended in failure.
I’ll bet the odds go up when you don’t mix up metric and English units.

Good luck to them.
UPDATE: SUCCESS! Animation of the landing and some subsequent operations
