Day 3 of #inktober2017 and today's rocket is the Agena target vehicle used to practice space rendezvous during the Gemini missions. Imagine you and a friend on escalators traveling in opposite directions and trying to throw two golf balls and have them connect exactly between you. That's kind of how tricky space rendezvous is. Buzz Aldrin's work on the subject was crucially important to the success of the missions, earning him the nickname "Dr. Rendezvous." #sciencecomicsrockets #intospacewego #nasa #illustration #inktober #drawings
