The secret to the beginning of life could be found on the surface of a comet

An Audacious Mission To Bring Back A Piece Of A Comet

Steve Squyres was feeling restless. It was late fall 2013, and the semester was wrapping up at Cornell, where he’d been a professor for more than 25 years. As head of NASA’s Mars Exploration Rover mission, he’d just marked 10 years tracking Spirit and Opportunity, two six-wheeled robots that went to the red planet. They’d been designed to roam the surface for just 90 days, scratching and drilling into rocks and examining soil in search of evidence of water. Nearly a decade later, Opportunity was still rumbling along. Squyres wasn’t bored by its persistence, but there wasn’t much left for him to do.

He called Stephen Gorevan, a longtime friend and a co-founder of Honeybee Robotics Ltd., which specializes in drills and sampling tools for planets and smaller bodies. Squyres had included a Honeybee tool on the rovers, and he figured Gorevan might have something new and cool to show him. Squyres proposed a visit to the company’s New York headquarters.

Over the course of a day, Gorevan talked up a dozen or so projects. One, in particular, stood out: a nearly 18-foot-long pogo-stick-like retractable arm that Honeybee envisioned sending to a comet. The robotic “touch and go” system would grab a small chunk from the comet’s surface, about 100 grams’ worth, store it in a capsule, and return it unspoiled to Earth.
