"The launch of the freighter is scheduled for March 28. It will have to orbit Earth twice and dock to the ISS three hours after the liftoff. However, this will be possible only if the ISS orbit is corrected in advance," the source said.
The source recalled that Progress MS-09 spacecraft was for the first time launched to the ISS under the three-hour scheme in July.
For decades, spaceships with crew and cargo typically flew for about 50 hours before reaching the ISS. In 2013, Russia introduced a six-hour route to the International Space Station, consisting of four orbits.
