... that astronaut Buzz Aldrin(pictured) discovered the Aldrin cycler, a means of repeatedly travelling between Earth and Mars? Source: "In 1985, Aldrin suggested that an Earth-Mars cycler may exist which repeats every synodic period. This was subsequently confirmed by Byrnes et al." ([1])
Overall: Some of the one-line paragraphs are unsourced, but the overall physics section is sourced, so that's fine. Interesting article DannyS712 (talk) 00:34, 30 December 2018 (UTC)
