Scientific testing of the International Space Station: In a 25-year history, after a power outage at the mission control center in Houston, NASA briefly lost contact with the International Space Station (ISS) on Tuesday for the first time, according to the media.
This outage marked the first time NASA had to rely on backup control hardware in Building 30 of the Johnson Space Center, according to CNN. Temporary interruptions in communications have occurred in the past as a result of improvements to ground systems or loss of contact with satellites.
