Phoenix on Mars

After traveling some 40 MILLION miles ( give or take a million or two) The Phoenix Mars lander approaches the red planet encased in a cocoon of a Delta Rocket. It must then slip from it's cocoon, check it's alignment, come screaming into the martian atmosphere at thousands of miles an hour, deploy its parachute, eject the heat shield, separate from the chute, fire it's thrusters, and make a landing. The track record for doing this has not been real great... about 50/50. Congradulations Phoenix, you made it!!!!!!
