Scott Kelly Hosts First Ever NASA Reddit AMA from Space

@StationCDRKelly Reddit AMA
You’re invited! 300 days of a #YearInSpace today! Ready to @Reddit? Join me Sat., Jan 23, 4pm ET to #AskMeAnything! Credit: @StationCDRKelly

NASA astronaut Scott Kelly will conduct the first ever NASA Reddit Ask Me Anything from space to help everyone understand what it means to spend a year in space.

A year is a long time to live without fresh air, gravity and human contact from loved ones. While science is at the core of Kelly’s groundbreaking spaceflight, it has also been a test of human endurance.

Kelly has just completed an unprecedented 300 consecutive days in space, and he has two more months before the end of his Year In Space mission which began last March. By the end of this mission, Kelly will be the first American to spend one continuous year in space and the record holder for total days in space and single longest mission. To say the least, he is currently NASA’s most experience astronaut.

The Reddit AMA will be held on Saturday, Jan. 23 at 4 p.m. ET. To follow the event, visit the Reddit AMA page. Kelly’s session will be added to the page once it begins.

Don’t be afraid to ask your questions. Connections back on Earth are very important when isolated from the entire world. So Kelly is looking forward to connecting with you during this event!

You can continue to follow Kelly’s Year in Space on his Twitter, Facebook and Instagram.
