Nasa tracking station

Nasa tracking station in Australia hit by staff strike

The Canberra Deep Space Communication Complex is one of three Nasa sites globally that provide constant radio contact with more than 30 spacecraft.

About 60 workers will go on strike for an hour, forcing staff at a US station to work overtime.

Nasa said the dispute would not affect operations.

While funded by Nasa, the tracking station is managed by Australia's government science agency, the Commonwealth Scientific and Industrial Research Organisation (CSIRO).
