INDUSTRIAL FEATURES

Photonics Makes Connections in Space May 1, 1999 — The first round-trip space mission to Mars would to bring back rock and soil samples for laboratory study on Earth. A critical aspect of such a mission will be the automated separation of a surface lander from an orbiting mother ship, and its docking after a visit to the planet’s surface. Unlike the Apollo missions to the moon of 30 years ago, no astronauts will be present to guide the two craft together. The ability to safely dock unmanned spacecraft is also likely to be important...
