Today is homecoming day for International Space Station Commander Scott Kelly of NASA and Flight Engineers Mikhail Kornienko and Sergey Volkov of Roscosmos as they prepare for landing in their Soyuz TMA-18M spacecraft at 11:25 p.m. EST tonight, southeast of Dzhezkazgan, Kazakhstan.

At this time, there are no concerns or issues being worked, and hatch closure is scheduled to occur at 4:40 p.m.

Kelly handed over command of the orbiting complex to NASA astronaut Tim Kopra in a ceremony on Monday, Feb. 29. When the Soyuz undocks, Expedition 47 formally will begin.

The landing of Expedition 46 marks the end of a year in space for Kelly and Kornienko. This is the first time that extensive research using exciting new techniques like genetic studies has been conducted on very long-duration crew members. NASA astronaut Scott Kelly is the first American to complete a continuous, year-long mission in space and is now the American who has spent the most cumulative time in space.

NASA Television coverage times for Soyuz activities are listed below. These activities also will stream online at https://www.nasa.gov/ntv.

    We have been watching you buzzing around above our Small rural property in south eastern rural Australia over the last 12 months, one of the best things I have seen was when you ripped past the bottom edge of the moon at a speed I could not even guess how fast you were traveling, “what a sight that was, to know you guys were actually in that small bright light”. Thank you for all you have done.
    Have a safe landing and we will look forward to watching you on TV.

    I have been following Scott Kelly and the International Space Station from Maine for the past year. One morning I set my alarm at 4:00 am so I could run outside in my bathrobe and slippers in ten degree weather to wave to Scott as he passed through the morning sky in Maine. Praying for a safe landing and hugs to you for an a accomplished mission in God’s world. Margaret….an old lady in The State of Maine!
