Expedition 48's Commander Williams installed an ISS space taxi dock with fellow astronaut Kate Rubins in mid-August. The dock would give Boeing and SpaceX a way to ferry astronauts to the station, finally freeing NASA from hitching a ride on Russian rockets. Since those taxis won't be ready until 2017 or 2018, though, Williams had to come home aboard a Soyuz with Russian cosmonauts Alexey Ovchinin and Oleg Skripochka. Besides breaking records and doing spacewalks, he also captured stunning photos of our planet from above during his stay -- check them out if you need one more reason to feel envious as a land-locked space lover.
