Opinion: Space exploration is now a robot's job

Washingtonpost.com: When it comes to space, we've outsourced the jobs to machines says Howard McCurdy in the Washington Post.

In his famous 1945 article anticipating communications satellites, Arthur C. Clarke opined that humans would need to operate the orbital switching stations. Wernher von Braun, who proposed a large space telescope, was sure that astronauts would be stationed nearby. For nearly every outpost in space, from spaceships and space stations to lunar colonies and Martian research bases, we thought humans would be there. We were wrong.

We did not anticipate the incredible advances in machine technology that the second half of the 20th century would bring. Technologies such as remote sensing, digital imaging, solid-state electronics, electric power generation, space communication and computer capacity reduced the costs and improved the capabilities of robotic spacecraft dramatically. We don't need technicians to change the film in space telescopes—the telescopes don't use film—and we don't need astronauts to maintain communications satellites.
