The University of Zurich accepted it within days. Its examiners, Alfred Kleiner and Heinrich Burkhardt, missed a mathematical slip that his assistant Ludwig Hopf found in 1911; corrected, the estimate came close to today’s value. From 15 January 1906 the patent clerk was Herr Doktor Einstein.

The computer was steering for a crater strewn with boulders. Armstrong took over and flew Eagle past it by hand. Post-flight analysis found 45 seconds of fuel left at touchdown, not the few seconds often quoted.

The Eagle has landed. — Armstrong Armstrong flew Eagle past a field of boulders by hand and set down on the Sea of Tranquility. The companion timeline Apollo 11 follows the mission to the second.

Four billion years after the Moon formed, life from Earth stands on it. The rocks brought home showed how closely the Moon matches Earth, evidence for the giant impact. See the Apollo 11 timeline, to the second.

Houston, Tranquility Base here. The Eagle has landed. — Armstrong Roger, Twan... Tranquility. We copy you on the ground. You got a bunch of guys about to turn blue. We're breathing again. — Charlie Duke, Houston Mare Tranquillitatis, 0.674° N 23.473° E. Transcript: Apollo Lunar Surface Journal
