Europe’s Last ATV Space Station Freighter Makes Fleet’s …

In the end, Europe's fifth and final space station freighter went out in more of a fiery blaze than with the "big bang" of its namesake.

The European Space Agency's (ESA) Automated Transfer Vehicle (ATV) 5, christened the "Georges Lematre" after the Belgian priest and astronomer whose work led to the Big Bang theory of the universe's origin, was intentionally destroyed as it plunged back into the Earth's atmosphere on Sunday (Feb. 15).

The unmanned spacecraft, the last of its type, came to its end at 1:11 p.m. EST (1811 GMT). [Europe's ATV-5 Space Cargo Ship Mission in Pictures]

The re-entry came a day after the ATV left the International Space Station (ISS), where it had been docked since last August. Launched on July 29, 2014, ATV-5 logged a total of 186 days in space.

Unpacked of its 7 tons of supplies and reloaded with 2.4 tons of trash, the "Georges Lematre" fulfilled its mission, including using its thrusters to readjust the altitude of the station to compensate for atmospheric drag, re-boosting to avoid debris and, in a first for an ATV last month, lowering the outpost's orbit in preparation for the arrival of the next cargo spacecraft.

Future visiting vehicles will not include the European ATV. Russian Progress vehicles, U.S. commercial Cygnus and Dragon freighters and Japan's H-II Transfer Vehicle (HTV) will resupply the space station going forward.

"The five ATVs have paid ESA's obligationsin the ISS program until 2017," Nico Dettmann, head of ESA's space transportation department, said in statement. "It has been decided to discontinue ATV, but to develop the MPCV-ESM (European Service Module) for NASA to compensate for ESA's ISS obligations until 2020."

The service module will provide propulsion and electrical power to NASA's Orion crew capsule on its missions into deep space. In return for developing the ESM, European astronauts will continue to live onboard the station to work on European experiments in ESA's Columbus lab through the end of the decade.

"This decision [offers] a European exploration perspective beyond low-Earth orbit, while building on ATV heritage," he said.

After the space shuttle, the 34-foot-long (10.3 meters) ATV was the largest spacecraft to resupply the space station, with enough volume to hold a double-decker bus. Powered by four solar panels in an "X-Wing" configuration, the ATV used a laser imaging system to autonomously dock to the orbiting outpost's Russian Zvezda service module.
