The ISS Progress 38 resupply ship was scheduled to dock to the aft end of the International Space Station’s Zvezda service module at 12:58 p.m. EDT Friday. However, docking was aborted when telemetry between the Progress and the space station was lost about 25 minutes before its planned docking.

As a result, the Progress vehicle continued on its trajectory and glided past the space station. At the time of the communication loss, the vehicle was approximately 3 km from the station. The unexpected cancellation was related to the KURS automated docking system. Russian ground teams are still analyzing data.

Russian and U.S. space station program managers will meet the morning of Saturday, July 3, to assess the next docking opportunity, preliminarily identified as approximately 12:17 p.m. EDT on Sunday, July 4. The Progress will conduct two engine firings tonight and another tomorrow to be in position for the potential docking Sunday.

Earlier in the day, Flight Engineers Doug Wheelock, Shannon Walker and Tracy Caldwell Dyson spoke to reporters on the ground. The flight engineers talked about the views of Earth and space from the cupola and how science in microgravity benefits people on the ground.

Wheelock spent some time in Japan’s Kibo laboratory module. He cleaned and activated various gear and reconfigured some of the module’s systems.

Walker worked with experiments in various science racks and collected and stored biological samples. She also participated in an experiment that measures visual perception during long-term spaceflight missions.

Caldwell Dyson set up the student experiments Kids in Micro-G and the Low Gravity Artist experiment. One part of these experiments studies simple phenomena such as blowing across a bottle filled with different volumes of water and observing if the sound is any different in microgravity. Another experiment will observe how different materials absorb water in microgravity. The experiments are being conducted in conjunction with students on Earth.

The three cosmonauts, Commander Alexander Skvortsov and Flight Engineers Mikhail Kornienko and Fyodor Yurchikhin, participated in a morning tag up with specialists on the ground discussing station inventory.
