A computer outage at the International Space Station could delay next week's launch of a commercial supply ship, according to NASA.
The space agency said on April 11 that the backup computer on the outside of the orbiting lab isn't responding to commands.
The main computer is working fine however, and the six-man crew at the ISS is in "no danger," according to NASA.
These computers control some robotic function that would be required for SpaceX's upcoming supply mission.
SpaceX is one of two companies contracted by NASA to keep the ISS supplied. They're supposed to launch an unmanned Dragon capsule on April 14 from Cape Canaveral.
The capsule contains approximately 5,000 pounds of supplies and science experiments.
A backup computer would have to be operating for redundancy of those robotic systems, according to the Associated Press.
The mission is already over a month late because of extra prep time required by the company and damage to an Air Force radar-tracking device needed for the launch.
Mission Control spent most of last night trying to figure out whether the computer can be repaired or if it has to be replaced.
If a replacement is needed, astronauts on the ISS would have to complete a spacewalk, according to AP.
NASA is currently still aiming for a Monday launch by SpaceX. This could change within the next couple of hours however.
