Automated Transfer Vehicle (ATV)

SPACECRAFT INFO

In terms of its role, the ATV was designed to complement the smaller Russian Progress spacecraft, possessing three times its useful payload capacity. Similar to the Progress, it would carry both bulk liquids and relatively fragile freight, which would be stored within a cargo hold maintained at a pressurized shirt-sleeve environment in order that astronauts would be able to access payloads without the need to put on spacesuits. The pressurized cargo section of the ATV was based on the Italian-built Multi-Purpose Logistics Module (MPLM), which was a Shuttle-carried "space barge" that had been previously used for transporting equipment to and from the Station. Unlike the MPLM, the ATV used the same docking mechanism as employed upon the Progress. The ATV, like the Progress, also serves as a container for the station's waste. Each ATV weighs 20.7 tonnes at launch and has a cargo capacity of 8 tonnes.
