Jonathan Goff

President and CEO, Altius Space Machines

ARM is the Asteroid Redirect Mission, and sometimes it seems that it doesn’t have a friend in the world. But it does, and Jonathan Goff of Altius Space Machines is one. Emily Lakdawalla reports on the Curiosity rover’s latest drill down into Mars. Bill Nye the Science Guy says LightSail is just one of the many cubesats planned for space missions. Bruce Betts helps Mat Kaplan with his pronunciation on this week’s edition of What’s Up.
