Comparing Heat Shields: Mars Science Lab vs. SpaceX Dragon

An anonymous reader writes "On August 5, 2012, the world’s attention was captured by the Mars Science Laboratory (MSL) landing. One of the key components in the multifaceted landing of the Curiosity rover safely on Mars was the Thermal Protection System (TPS), or heat shield, on the spacecraft carrying the rover.

The thing people remember most about the heat shield is when it popped off the spacecraft and flung like a frisbee across the Martian landscape, landing with a plume of dust. Measuring nearly 15 ft (4.5 m) in diameter, the MSL heat shield was the largest to ever travel to another planet."
