“Albert Einstein,” the European Space Agency’s (ESA) Automated Transfer Vehicle, or “ATV,” has safely docked with the International Space Station (ISS). Docking occurred Saturday at 10:07 a.m. EDT to the rear end of the station’s Zvezda service module. The docking was automated and concluded the spacecraft’s 10-day journey to the orbiting laboratory.

The ATV-4, dubbed “Albert Einstein” in honor of the famous physicist, launched on May 5 atop the powerful Ariane 5 rocket from Kourou, French Guiana. ATV-4 carried some 5,465 pounds of dry cargo, hardware, and supplies. Also on board was 1,896 pounds of propellant, which will be transferred to Zvezda, as well as 5,688 pounds of propellant, which will be used to modify the space station’s orbit. Of great importance to the Expedition 36 crew are the 1,257 pounds of water and 220 pounds of oxygen and air.

According to a statement released by NASA, the 13-ton ATV is the heaviest spacecraft ever to be sent into the black by ESA.

Four days before the ATV-4 docked to the station, the same port was utilized to send the Russian Progress spacecraft, packed with trash, on its way.

The Progress spacecraft also reviewed some of its handy work on its way out. The Russian-built craft took imagery of the port to look for possible damage that might have occurred when it docked.

The Progress 51’s Kurs antenna failed to deploy; it was thought this antenna, which was in the wrong position, might have damaged the docking port, and the event raised concerns that the Albert Einstein ATV-4 would have problems docking to the ISS. This turned out to be inaccurate and the Albert Einstein docked with no issues.

The Progress resupply vessel will spend a couple days orbiting our planet before it conducts a fiery plunge into Earth’s atmosphere Tuesday, where it will burn up above the Pacific Ocean. While on orbit engineers will conduct tests on the cargo vessel.

The crew on board the station will offload the supplies on board Albert Einstein and replace them with trash. If all goes according to plan, the Albert Einstein will undock from the ISS in late October. Like Progress, the ATV is not reusable; it too will end its days in a fiery reentry in Earth’s atmosphere somewhere above the Pacific. In the meantime, the crew on the ISS will use the Albert Einstein’s extra storage space, thus providing them with more habitable volume.  Components of ESA’s ATV will be used to aid the United States’ next human-rated spacecraft, Orion.
