It's always a momentous (if melancholic) moment when astronauts finish their stints aboard the International Space Station, and NASA is determined to capture every last minute of the occasion this time around. It's livestreaming the departure of astronauts Kate Rubins, Anatoly Ivanishin and Takuya Onishi as they end 115 days in orbit. Things get started in earnest today (October 29th) at 4:45PM Eastern, when the crew says its goodbye and enters the Soyuz spacecraft. The undocking should begin at 8:37PM, and the deorbit burn should start at 11:06PM. If all goes according to plan, the team will touch down on Earth at 11:59PM.
