space station. The Progress M1 is a derivative of the Progress M, optimized to carry more fuel, at the expense of dry cargo and water. It entered service in 2000, and was retired in 2004. A modernised version, incorporating the upgrades made to the Progress M 11F615A60 was scheduled to enter service in 2011, however this was cancelled before it made its first flight. The upgraded Progress MS spacecraft flew for the first time in December 2015.
