The six #PocketQubes start to spread out, easily visible when using the awesome poliastro
CZMLExtractor together with the new czml3 CesiumJS widget in a jupyter-notebook. (manually annotated, using space-track TLEs, note: some elements are 3 days old)
How does the drag term B* depend on the orbital altitude for cubesats in low orbits?
TLEs from SpaceTrackOrg
and the CelesTrak cubesat category.

Having some fun with Python. Can you predict the result of the following:

Erfolg vor Gericht: Wir dürfen das Glyphosat-Gutachten wieder veröffentlichen! Grund waren formelle Fehler der (sehr teuren) Anwälte der Bundesregierung.
Jetzt müssen wir das #Zensurheberrecht abschaffen. Und verklagen die Bundesregierung dafür doppelt.

I can’t believe what I’m seeing! While running a facial recognition pilot, one man (understandably imho) covered himself up. The police forced him to show his face (& then fined him for disorderly conduct). This is dangerous & terrifying.
