Crew Returns from Space Station Mission
- The Flight Controllers in Houston are preparing for the return of three crew members from the International Space Station, including Loral O'Hara, Oleg Novitskiy, and Marina Vasilevskaya.
- Vasilevskaya and O'Hara are concluding a two-week mission on the International Space Station.
- Novitskiy and Vasilevskaya spent 14 days in space, 12 of which were aboard the space station, completing 224 orbits of the Earth and traveling 5.9 million statute miles.
- The crew members said goodbye to their colleagues and departed through the Rassvet port, beginning their journey home.
- The Soyuz engines will ignite for a 4:41 retrograde burn to drop out of orbit, followed by an automatic pyrotechnic separation of the Soyuz vehicle.
- The crew will experience maximum G-loads of about four to five Gs during descent, with chutes deploying at specific altitudes before touchdown.
- The landing site is approximately 91 miles south of Dzhezkazgan, where the crew will undergo preliminary medical exams and change into comfortable clothing before boarding helicopters for Kazakhstan.
- Novitskiy, as the commander, will receive instructions from the Russian flight control team in Korolev as they begin to feel the pull of gravity.
- The deorbit burn was successfully completed, and the next step will be the separation of the three modules of the Soyuz spacecraft.
- The Expedition 71 crew on the International Space Station will monitor the landing and have an off-duty weekend planned, with future activities including a Russian spacewalk and the return of science equipment.

Russian Soyuz Descent and Landing Details
- The Russian Mi-8 helicopters, six in total, are en route to the landing zone, where they will form a circular flying pattern around the landing site along with an Antonov aircraft serving as the command center.
- Novitskiy has chosen his call sign for the Soyuz descent and landing, aiming to maintain communication during the descent back into Earth's atmosphere.
- The touchdown is expected to occur at 2:17:36 AM Central Time, 3:17:36 AM Eastern Time, and 12:17 PM at the landing site in Kazakhstan, 3 miles southeast of the town of Dzhezkazgan, with favorable weather conditions.
- The Russian ballistics experts have forecasted the touchdown coordinates for the Soyuz spacecraft at a latitude of 47.24° North and a longitude of 69.39° East.
- The Soyuz is in good condition, with all systems functioning well, and the module separation is scheduled to occur at an altitude of 87 miles above the Earth.
- The Russian flight controllers have ground support teams and all-terrain vehicles ready for the Soyuz's return, with good visibility expected for landing.
- The module separation of the Soyuz vehicle is planned to occur at an altitude of 87 miles above the Earth, with the descent module targeting the landing site southeast of Dzhezkazgan.
- The Soyuz is expected to enter the Earth's atmosphere, experiencing peak heating in the plasma regime, with communication expected to be temporarily lost until the Soyuz emerges from this phase.
- The main parachute of the Soyuz covers an area of about 1,000 meters, slowing the descent rate to 2.7 meters per second, with the harnesses allowing for a canted angle descent before transitioning to a vertical descent.
- Visual confirmation from the search and recovery forces is awaited as the Soyuz descends under its parachute, with approximately 12.5 minutes remaining until touchdown.

Successful Soyuz Landing Marks ISS Mission Success
- Video on the front screen of the Russian Mission Control Center shows the main chute of the Soyuz and white smoke from hydrogen peroxide and oxygen being vented.
- Time to touchdown is 11:47, with a large orange and white chute fully reefed.
- The Soyuz is descending under its chute, with the heat shield jettisoned and a radio beacon signal for tracking.
- Ground forces are in place for extraction as the Soyuz descends, with helicopters landing nearby to check for toxic gases.
- The crew is feeling good, with the Soyuz descending at its nominal rate.
- The crew's seats will be upright for landing, with soft landing engines firing for a braking maneuver.
- The Soyuz lands on its side, with the crew in good shape and extraction procedures beginning.
