er lawk
- n a chamber that provides access to space where air is under pressure
- The primary payload on the mission is the joint airlock module, which will require two space walks to attach it to the Space Station.
- Then, as the sun reappeared, they began to make their way through the maze of trusses on Skylab's telescope mount, circled part way around the outside of the cylindrical airlock .
- Major drawback of the parasol: the airlock mechanism would prevent the astronauts from seeing how the operation was proceeding outside the spacecraft.
