Kvant problems. By late in the year, investigators in Britain and Holland
noted sporadic problems with their TTM wide-angle X-ray camera and with ESA’s Sirene 2 gas-scintillation proportional counter. They queried the TsUP in Moscow as to whether crew activity could be causing interference with the instruments.[2] Cosmos 1897. This was a communications relay satellite of the Altair/SR series, designed to increase the amount of time Mir could be in touch with the TsUP on each orbit. It was launched on November 26 and stationed in geosynchronous orbit at 95° E. At the same time, fatigue reduced the cosmonauts’ workday to 4.5 hr.[3][4] |
