The Automated Transfer Vehicle 1 (ATV-1) was the first spacecraft in the Automated Transfer Vehicle series developed by the European Space Agency (ESA) for resupply missions to the International Space Station (ISS). The primary objective of ATV-1 was to deliver cargo, supplies, and experiments to the International Space Station (ISS) to support its crew and operations. ATV-1 served as a key component of the ISS resupply program, providing essential resources for the astronauts onboard.
