International Space Station hit by major power shortage

International Space Station hit by major power shortage

SpaceX was supposed to launch a shipment Wednesday.

Williams claims nobody was injured and the anomaly has been included.

This week's resupply mission to the International Space Station, CRS-17, has moved back to early Friday morning while an electrical issue on ISS is evaluated.

Unfortunately, the space station's power distribution system is acting up, and it will take some time to complete the repairs.

On Monday, station crew discovered an issue with a unit that distributes power to two of the eight power channels on the ISS.

When the Dragon reaches the space station about three days after launch, Canadian astronaut David Saint-Jacques will grapple the cargo ship with the space station's robotic arm for docking. Flight controllers are now working to route power through the remaining six power channels. CanadArm 2 has two power systems - and while only one is used, the other is a backup. Nasa wants to replace the failed unit to restore full power before sending up the SpaceX Dragon cargo capsule. In a statement, NASA said: "There are no immediate concerns for the crew or the station".

Flight controllers will use the robot arm to replace the bad unit with a spare later this week, saving the astronauts from going out on a spacewalk.

The spacecraft, filled with 3 tons of experiments, provisions and supplies, was due to arrive on Saturday at the ISS if it had launched on Wednesday.

SpaceX, meanwhile, is still investigating this month's fiery loss of its new Dragon capsule designed for astronauts.

It's only been a little over a week since a static test fire of SpaceX's Crew Dragon resulted in what appeared to be the complete destruction of the vehicle.

SpaceX and NASA have offered few details.
