Russia is to revise its space program, the national space agency said on Tuesday after a newspaper published a report that billions of dollars of cuts may be on the way, including to ambitious moon exploration plans.

Several Russian government ministries were engaged in revising the space program up to 2025, Roscosmos said in a written statement.

It did not give details. But the Roscosmos statement and a report in Izvestia newspaper suggested Russia's prestigious space program may also have fallen victim to government cutbacks brought on by hard times.
