"NASA's Phoenix Mars Lander aims to not flame out when it descends to the arctic surface of the red planet in less than two weeks.
"The new Martian probe will try to avoid the fate of its crashed predecessor, NASA's Mars Polar Lander, when deploying a parachute and braking rockets to slow its plunge and make a successful three-point landing.
" 'This is not a trip to grandma's house,' said Ed Weiler, associate administrator of NASA's Science Mission Directorate at the agency's headquarters in Washington, D.C. 'Putting a spacecraft safely on Mars is hard and risky.' "
The Space.com article goes into more technical detail about what happened as the Mars Polar Lander attempted a landing, and what's been done to prevent a repeat of that crash.
