Yury Vladimirovich Usachov (Russian: Юрий Владимирович Усачёв; born October 9, 1957) is a former cosmonaut who resides in Star City, Moscow.

The Soyuz TM-18 spacecraft carrying Usachov with cosmonauts Viktor Afanasyev and Valeri Polyakov lifted off from the Baikonur Cosmodrome at 10:05:34 UTC.

After two days of solo flight, Soyuz TM-18 docked at the Kvant-1 module of the Mir space station on January 10 at 11:15 UTC.

He was on board Mir on January 14, when the departing Soyuz TM-17 spacecraft struck Kristall module two glancing blows during the customary inspection fly-around prior to the deorbit burn.

Usachov and Afanasyev uneventfully returned to Earth on board the Soyuz TM-18 descent module, which landed 110 km north of Arkalyk in Kazakhstan at 10:32:35 GMT on July 9, 1994.

The Soyuz TM-23 spacecraft carrying Usachov with cosmonaut Yuri Onufriyenko lifted off from the Baikonur Cosmodrome on February 21, 1996, at 12:34:05 UTC.

After two days of autonomous flight, the Soyuz spacecraft docked with the Mir space station's forward-facing port on February 23 at 14:20 UTC.

On September 2, 1996, Usachov, Yuri Onufriyenko and Claudie André-Deshays returned to Earth on board the Soyuz TM-23 capsule.

[7] On Flight Days 5 and 6 of the mission, Usachov and Helms replaced two of six batteries in the Zarya module along with some associated battery-charging electronics.

Usachov and Helms also installed a new Radio Telemetry System in the Zarya module, a memory unit that can store data on board when the station is not in communications with the ground.

The Expedition 2 crew of Usachov and NASA astronauts Susan Helms and James Voss lived and worked aboard ISS for the next 167 days.

[3] During Expedition 2, research facilities launched to the ISS included a Human Research Facility, two EXPRESS (Expedite the Processing of Experiments to the Space Station) Racks, one of which contains the Active Rack Isolation System and the Payload Equipment Restraint System.

A major focus was on gaining a better understanding of how to protect crew members from radiation while working and living in space.

The two spacewalkers also inflated an aluminum and nylon pup-up model of a Pepsi Cola can, which they then filmed against the backdrop of Earth.

They installed the modular optoelectrical multispectral scanner (MOMS) outside Priroda and handrails on the Kvant-2 module to facilitate moving around outside the station during future extravehicular activities.

During the spacewalk, Usachov and Onufriyenko installed the Rapana truss structure (an experiment mounting point) to the Kvant-1 module.

He and NASA astronaut James Voss donned spacesuits entered the small, spherical transfer compartment at the forward end of the Zvezda Service Module during an "internal" spacewalk.

[12] Just after the ISS flew over the dark side of the Earth, they removed a hatch at the Earth-facing part of the compartment to open it to the vacuum of space and officially begin the spacewalk at 9:21 a.m CDT.

During the 19-minute spacewalk which ended at 9:40 a.m. CDT, Usachov and Voss moved a docking cone from storage and using a rotating handle, installed it in the lower port hatch.
