NASA's Game-Changing Robotics

“Over the years, I’ve asked people, ‘If you had a robot, what would you want it to do for you?’” said Rob Ambrose, principal investigator for NASA’s Game Changing Development Program and chief of the Software, Robotics, and Simulation Division at NASA’s Johnson Space Center. When he asks astronauts, they usually tell him they want the robot to do chores.

Primer Stops Corrosion Without Requiring Rust Removal

Coating used on launch pads protects bridges, condominiums, and other structures from corrosion.In the mid-1990s, Surtreat Holding LLC, based in Pittsburgh, PA, developed two corrosion inhibitors that worked by chemical means, and were designed to be applied to the surface of concrete, where they would migrate to the steel rebar inside. By 1996, the formulas still had not been formally tested and validated.

NASA’s Infrared Sensor Spots Near-Earth Asteroids

The Near-Earth Object Camera (NEOCam) is part of a proposed NASA mission to find potentially hazardous asteroids. In a Q&A with Photonics & Imaging Technology, NEOCam principal investigator Amy Mainzer ex plains how the NEOCam chip, a stamp-sized mega pixel infrared sensor, detects the faint heat emitted by near-Earth objects circling the Sun.

Recycling Technology Converts Plastic Waste to Energy

NASA’s expertise in rocket engine improvement helps optimize plastic recycling process equipment. As good as it feels to throw plastic items into the recycling bin, the fact is most of that plastic goes unrecycled, according to Jim Garrett, a veteran of the oil and gas industry. “It’s a dirty little secret in America that 90 percent of our plastic ends up [in landfills], if not in our oceans.”
