Throwing Physics a Curve

David Peters studies the aerodynamics of baseballs and helicopters

1 min read

It’s March, and that means two things for David Peters—the start of the baseball season and appearing on television. Ever since his hometown St. Louis Cardinals won the 2006 World Series, he’s appeared regularly on local news to explain the mechanics behind curveballs and suchlike.

”I’m a ham—I don’t mind being the center of attention,” he says, laughing. ”And it gives us a hook for explaining science to the public.”

For a deep dive into the engineering behind the James Webb Space Telescope, see our collection of posts here.

When the James Webb Space Telescope (JWST) reveals its first images on 12 July, they will be the by-product of carefully crafted mirrors and scientific instruments. But all of its data-collecting prowess would be moot without the spacecraft’s communications subsystem.

The Webb’s comms aren’t flashy. Rather, the data and communication systems are designed to be incredibly, unquestionably dependable and reliable. And while some aspects of them are relatively new—it’s the first mission to use Ka-band frequencies for such high data rates so far from Earth, for example—above all else, JWST’s comms provide the foundation upon which JWST’s scientific endeavors sit.
