The project was delayed by higher-priority test and production of third generation systems while at the same time responding to government crash programs for 'star wars' systems. But the revised schedule was almost immediately followed by the disintegration of the Soviet Union and the attendant financial crisis.

In 1989 yet another ion engine-powered Mars project was proposed by NPO Energia. In the place of the nuclear reactor of previous designs, solar panels would be deployed in huge farms of panels.

Unmanned resupply vessel to Mir. Conducted fourth test of Buran ejection seat during ascent to orbit. The K-36M.11F35 seat was installed in an 'experimental droppable compartment' installed in place of the Launch Escape Tower engine on top of the shroud. Delivered Bulgarian Spektr 256 spectrometer, power supplies for failed equipment. Docked with Mir on 18 Mar 1989 20:50:46 GMT. Between April 9 and 17 boosted Mir into a 373 X 416 km storage orbit after the decision was made to delay remanning the station. However these maneuvers resulted in the spacecraft running out of fuel. Undocked on 21 Apr 1989 01:46:15 GMT. Destroyed in uncontrolled decay of orbit on 25 Apr 1989 12:12:00 GMT.

Phobos 2 operated nominally throughout its cruise and entered Mars orbit on January 29, 1989. Contact with the vehicle was lost on March 27, 1989 shortly before the final phase of the mission during which the spacecraft was to approach within 50 meters of Phobos' surface and release its two landers. The cause of the failure was determined to be a malfunction of the on-board computer.
