One morning in November 2014, Kamal Oudrhiri, a colleague of mine at the Jet Propulsion Laboratory (JPL), in Pasadena, Calif., burst into my office with an intriguing proposition. A first-of-its-kind satellite was headed for Mars. The satellite would fly alongside NASA’s InSight Mars Lander , relaying data in real time back to Earth during the lander’s critical entry, descent, and landing. “We have to achieve 8 kilobits per second, and we’re limited in terms of power. Our only hope is a large antenna,” Oudrhiri explained. “Oh, and t ...
