Video signals and other feedback had to pass through a complex communications network involving ISS mission control, ground antennas, and relay satellites. This 90,000km path introduces about a second's delay into proceedings. | |
Nonetheless, Mogensen managed to get the peg to plug the hole with the aid of a laser guided tool. | Nonetheless, Mogensen managed to get the peg to plug the hole with the aid of a laser guided tool. |

The rover was positioned at Esa’s technical centre in Noordwijk, the Netherlands. The current altitude of the ISS is 402km. It is moving around the Earth at roughly 28,000km/h. | The rover was positioned at Esa’s technical centre in Noordwijk, the Netherlands. The current altitude of the ISS is 402km.

Among his other experimental tasks - he will be testing a water purification system that relies on a new nanotechnology membrane, and wearing a new "skin suit" designed to alleviate back problems. | Among his other experimental tasks - he will be testing a water purification system that relies on a new nanotechnology membrane, and wearing a new "skin suit" designed to alleviate back problems. |
