And since then, the trend has been for more and more ground supervision. The International Space Station, for example, is largely operated from the ground. But deep-space missions would involve communication delays that are much longer, ranging from a few seconds to many minutes—time lags that would make ground-based control impractical. To sidestep that problem, NASA is trying out techniques such as text-based “chat” sessions and a procedure for monitoring astronauts’ progress on tasks without having to interrupt them for status updates.
