04-寻找火星生命

Heather lost her opportunity to make that discovery back in 1999.

I, unfortunately, have seen the loss of a mission before, in Mars Polar Lander. I was on the TEGA I team.

NARRATOR: Phoenix carries TEGA II. It's Heather's second chance for success.

Your first impulse, when you have a failure like Mars Polar Lander is, "I am never doing this again."

But on the other hand, when you've got it in your blood and you want to do exploration and. . . you actually have to turn it around as an opportunity.

NARRATOR: Second chances are very rare in this business.

The TEGA team has put their professional. . . and personal commitments on the line. . . one last time.

It all boils down to seven minutes of terror.

It will take seven minutes for Phoenix to decelerate from nearly 13,000 miles an hour to a soft touchdown on Mars.

This time, the preplanning, the engineering, the timing. . . all of it must pay off.
