Roscosmos said the mission was dedicated to the 75th anniversary of the defeat of Nazi forces, which Russia usually marks with great fanfare and a massive military parade in Moscow.
However this year's May 9 events have been drastically cut back because of the coronavirus pandemic.
The ISS currently has three crew - American Chris Cassidy and Russians Ivan Vagner and Anatoly Ivanishin who boarded earlier this month.
The ISS is now a rare example of cooperation between Russia and the West. It has been orbiting Earth at about 28,000 kilometres (17,000 miles) per hour since 1998.
