"Space station astronaut controls robot on Earth"
[...]"Astronaut Sunita Williams, commander of the International Space Station's current Expedition 33 mission, used NASA's experimental Disruption Tolerant Networking (DTN) protocol to drive a small LEGO robot at the European Space Operations Center in Germany late last month."[...]
"NASA's DTN architecture is a new technology designed to enable standardized communications over long distances and through time delays, agency officials said. At its core is something called the Bundle Protocol (BP), which is similar to the Internet Protocol, or IP, that serves as the heart of the Internet here on Earth.
The big difference between the two is that IP assumes a seamless end-to-end data path, while BP is built to account for errors and disconnections -- glitches that commonly plague deep-space communications."
