Ground controllers have completed troubleshooting work after last week’s false alarm indicating an ammonia leak. Heat exchangers and thermal control systems on the U.S. side of the International Space Station have been recovered and reintegrated and are operating in excellent shape.

Commander Barry Wilmore was scrubbing cooling loops on a U.S. spacesuit when he heard an abnormally loud fan pump separator in the suit. He alerted spacesuit engineers who are currently discussing the problem on the ground.

Crew members over the weekend noticed a bad odor coming from Europe’s docked Automated Transfer Vehicle and closed its hatch. European controllers then performed waste tank leak checks and didn’t find any leak indications. Flight Engineer Alexander Samokutyaev is set to reenter the vehicle wearing a respirator mask to investigate.
