UPDATE (9:35 a.m. EDT): Russian flight controllers have continued to try and recover command capability with the ISS Progress 59 cargo craft this morning. The most recent ground pass started at 9:20 a.m. EDT and flight controllers reported no change in the issues with receiving telemetry data from the unmanned craft. The Russian flight control team attempted to command the vehicle over four orbits flying over Russian ground sites with no success.

The next series of ground station passes is expected to resume late Tuesday evening. Teams are standing down on the Thursday docking attempt while Russian teams continue to analyze data and develop a troubleshooting plan going forward.

UPDATE (8:15 a.m. EDT): Russian flight controllers are continuing to troubleshoot issues with the ISS Progress 59 cargo craft. The spacecraft made another pass over Russian ground stations and continued to experience telemetry problems regarding the deployment of navigational antennas and the pressurization of the manifolds in the propulsion system. Flight controllers also confirmed that the vehicle had entered into a slow spin and have issued commands to attempt to control it.
