America's last space shuttle missions occurred in 2011, with the successful launches of Discovery, Endeavor, and Atlantis. Photojournalist Dan Winters captured these landmark events with incredible access to the NASA program in its final days.
For the photographs, Winters set up automatically controlled cameras at particular points around the launch pad (some as close as 700 feet from the launch) so he could capture the stunning takeoffs in incredible detail.
Winters has been fascinated with space shuttle launches since he first witnessed Astronaut John Glenn's 1998 return to space in person and found it to be "visually unbelievable."
"It's one of those things that's hard to describe or imagine until you see it," Winters told Business Insider. "There's a lot of anxiety because it's such a controlled chaos and you know there's a potential for failure ... There are over two million parts on the shuttle and every single part has to have 100 percent performance."
Winters has collected his work from the project in a book called "Last Launch: Discovery, Endeavor, Atlantis," from University of Texas Press. It is available for purchase here. Here's where you can see the space shuttles in person.This is the space shuttle Endeavor, as it begins to launch for the final time in 2011:
