news report about Mierscheid disappearance and existence economist.com/news/europe/21… do not underestimate German humor
member of parliament in Berlin disappears during #SolarEclipse after being last seen on bridge bearing his name
#SoFi mit Abgeordnetem Mierscheid in Berlin auf dem nach ihm benannten Steg gesehen. Er blieb danach verschwunden.
special relativity: time goes slower when you travel very fast. ISS is fast but not very high, so time goes slower
general relativity: time goes faster when you are further away from Earth
Jubel in Baikonur beim Öffnen der Luke. Ende eines langen Tages für alle. Es ist alles gutgegangen.
Eben stand man sich in Baikonur gegenüber, jetzt sehen Familie/Freunde wie @AstroSamantha und Kollegen in der #ISS
Leider nichts zu sehen vom #ISS Überflug: Zuviele Wolken in Baikonur heute morgen um 8 Uhr.
WOW. Start ist im Nachthimmel greller als jedes Foto oder Video das zeigen kann. Nach 30 Sekunden verschwindet die Rakete über Wolkendecke.
Crew unterwegs zur Rakete. kleine Stärkung für die Begleiter. Noch 3 Stunden.
countdown to launch at 3:01 local time
#MAPHEUS-3 shifted to next year to avoid possible failure of a control unit -- best possible decision, still a bit sad
granular expt #MEGraMa tested on parabolic flight, drop tower #ZARM dlr.de/mp/DesktopDefa… soon on #DLR rocket #MAPHEUS-3 dlr.de/dlr/desktopdef…
there is also an English description of our experiments dlr.de/dlr/en/desktop… for the start: let's keep our fingers crossed
