Ron Strang was on patrol in Afghanistan when a primitive land mine exploded.
"When it went off, it came across the front of my body," Strang says. Though he survived the blast, his left leg was never the same. Shrapnel destroyed most of the muscle on his left thigh. He used to run, swim and hike. But even after he recovered, those days of carefree movement were gone.
This month, NASA revealed new details of the plan to send humans to Mars by 2030. It's an elaborate and expensive mission, involving a giant deep-space rocket, and roping an asteroid into the moon's orbit to use as a stepping stone to Mars.
But there are still some serious questions about a manned expedition to Mars. Namely, is it safe? That's where astronauts Scott and Mark Kelly come in. The Kelly brothers are identical twins, and the only siblings ever to both fly in space.

As search efforts intensify around the site of Washington state’s devastating mudslide, geologists are looking into causes of the rapid collapse of the 1,500-foot-wide segment of hillside in Snohomish County that suddenly cut away and crushed the homes and roads below.
The chief culprit appears to have been the glacial composition of the hillside, which is made of silt, clay and soil, and very little rock, which tends to be very loose.
David Hyde talks with Philip Mirowski, author of "Science Mart: Privatizing American Science," about why he thinks the move to privately funded science is undermining the quality of the research.
"The types of science that are being done are changing, and the way in which science is being done is changing," Mirowski said. "In fact, the quality of some of the science is being affected by it too."
