International Space Station hit by major power shortage

SpaceX delivery delayed after old power-switching unit malfunctions

The International Space Station has been hit by a major power shortage that has forced a delivery from SpaceX to be delayed.

SpaceX was supposed to launch a shipment on Wednesday. But an old power-switching unit malfunctioned at the space station on Monday and knocked two power channels offline. The six remaining power channels still worked normally, according to Nasa.
