The Svalbard vault is protected by two airlocks, at the end of a tunnel sunk 160 metres into the permafrost of Norway's Arctic archipelago, outside the village of Longyearbyen, one of the world' s most northerly habitations.
We think we’re gonna terminate EVA case for EV2. So Luca, we’ll have you head back to the airlock, Chris, we’ll get a plan for you to clean things up and then join him here in a minute.”
They use a special receptor that works a bit like a key to a door, allowing the virus to attach itself to a cell, like a spaceship connecting to an airlock.
And as construction progresses, prebuilt and preintegrated hardware like airlocks or life support equipment brought from Earth are inserted into the print until finally they're sealed at various connection points.
The extravehicular activities (EVAs) started at 1: 35 p.m. Beijing Time on Saturday, when taikonaut Cai Xuzhe opened the hatch of the airlock cabin of the Wentian lab module.
During their mission, the Shenzhou-16 crew will continue to conduct extravehicular activities and cargo airlock extravehicular tasks, space science experiments, and the trial of new technologies.
