Astronaut Reid Wiseman tweeted this Vine shot from an observation window on the International Space Station this week. It shows one full orbit of the ISS around planet earth. It's the first Vine recorded from outer space, and it's literally out of this world.
Reid is following in a great tradition of outer-space social media here: Col. Chris Hadfield was a prolific tweeter during his ISS missions, and Astronaut Mike Massinimo sent the first tweet from space all the way back in 2009.
But there's something particularly awe-instilling about seeing the ISS's orbital path so vividly. As Reid's caption explains, the sun never sets on this 90-minute orbit because the ISS is travelling along the terminator line, the border between light and darkness on the face of the earth.
In space, social media is always awesome. [@astro_reid]
