I am humbled and excited by new opportunities for me to support and share the amazing work NASA is doing to help us travel farther into the solar system and work with the next generation of science and technology leaders. Scott Kelly amazeexcitefar share on social
A year is a long time to live without the human contact of loved ones, fresh air, and gravity, to name a few. Scott Kelly aircontactfresh Change image and share on social
I don't mean to say it's not fresh on the space station, but there's nothing like new, cold air coming into the capsule. Scott Kelly aircapsulecold Change image and share on social

Going to Mars is a bunch of baby steps, and it started off with the first human in space, Yuri Gagarin. Scott Kelly babybunchgagarin Change image and share on social
People do really well on space missions, but it's the physiological, the medical stuff, the stuff like radiation, loss of bone mass and muscle mass and density. It's those things that we need to figure out. Scott Kelly bonedensityfigure share on social
