Mikhail Borisovich Kornienko (Михаил Борисович Корниенко; born 15 April 1960) is a Russian cosmonaut who has undertaken multiple missions to the International Space Station (ISS).

[3] The mission, launched aboard Soyuz TMA-16M, aimed to study the physiological and psychological effects on humans during extended periods of spaceflight.

The collected data are intended to aid preparations for future missions requiring extended human presence in space.

He took part in extravehicular activity (EVA) tests in simulated zero-gravity at the hydrolab and at the Selen dynamic stand.

In the process of this work he acquired experience in organizing extravehicular repair/refurbishment and assembly activities on the Mir orbital station.

He lifted off on 2 April 2010, along with fellow Russian cosmonaut Aleksandr Skvortsov and NASA astronaut Tracy Caldwell-Dyson aboard Soyuz TMA-18 from the Baikonur Cosmodrome.

[8] Ending Expedition 24, the Soyuz TMA-18 spacecraft carrying Mikhail Kornienko, Alexander Skvortsov and NASA astronaut Tracy Caldwell-Dyson undocked from the space station at 10:02 pm EDT on 24 September 2010.

From inside the Pirs docking compartment they checked out the Orlan systems, practiced translation movements and tested their mobility.

During the spacewalk, Kornienko and Yurchikhin outfitted the Rassvet module's (MRM1) Kurs automated rendezvous system, installed cables and remove and replaced a video camera.

[10] The spacewalk began at 04:11 UTC as Kornienko and Yurchikhin donned in Orlan spacesuits, depressurized the internal volume of the Pirs docking compartment airlock and ventured outside into space.

The goal of their yearlong expedition aboard the orbiting laboratory was to understand better how the human body reacts and adapts to the harsh environment of space.

[13] Data from the 12-month expedition will help inform current assessments of crew performance and health and will determine better and validate countermeasures to reduce the risks associated with future exploration as NASA plans for missions around the moon, an asteroid and ultimately Mars.
