Houston: Tranquility Base here. The Eagle has landed! – Almost 50 years ago, on 20 July 1969 at 20:17 UTC, Neil Armstrong and Edwin ‘Buzz’ Aldrin landed on the Moon, achieving a goal that had become so important to the United States of America that for a decade they had prioritised it above almost everything else. Towards the end, the landing became quite difficult because there was only enough fuel for a few more seconds of flight and the landing approach almost had to be aborted. However, the two new national heroes – and not forgetting Michael Collins, the pilot of the Command and Service Module that remained in lunar orbit – mastered this situation with ice-cool professionalism. They ignored – after an “OK” from ground control – yet another (false) radar alarm. Admittedly, the first crewed Moon landing was largely a political demonstration. But regardless of how today’s historians judge the outcome of the ‘race to the Moon’ that culminated in Armstrong’s “That’s one small step for [a] man, one giant leap for mankind”, the Apollo project was much more than just 12 astronauts walking on the Moon. For technology, but even more so for scientific research, this was a giant step forward: the Apollo programme was the birth of planetary research.

The Saturn V rocket lifted off at an almost frighteningly slow speed at 09:32 local time (13:32 UTC) from Launch Complex 39A at the Kennedy Space Center, on the eastern coast of Florida. Every second, 13 tonnes of fuel were pumped into the five engines and burned; each of them produced 7500 kilonewtons of thrust.
The compact German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) Eu:CROPIS satellite is now rotating in space at a rate of 17.5 revolutions per minute, generating a gravitational force in its interior similar to that found on the Moon. After its launch on 3 December 2018, DLR engineers successfully tested and commanded the spacecraft.
