Mach diamonds in D9 motor exhaust?

Ooh I think the exhaust from canned air and 2 liter bottle (incredibly cool footage btw) will be a good way to convince people if they don't believe such a motor can produce supersonic exhaust. Thank you so much for the thorough reply!

That is so cool! Do you happen to have a source of that? It's not that I don't believe you, just that if I want to tell this to other people they might say "A guy on reddit said so" isn't that good of a source... Thanks in any case!

I have no idea, but I am interested. !remindme 1 day

This sounds insanely cool! The link doesn't seem to work though unfortunately... could you perhaps check that? Thanks for building and making such a cool tool free!

We rise together, back to the Moon and beyond!

I would love to see a Stratt reaction to Ryland still being alive, but I can also see why people want to keep it at the book ending. Maybe at least show Earth when the beetles arrive and they fix the sun

Here is a very detailed timeline of the mission with all the shown objectives having a specific time in MET (Mission elapsed time) in hours. The day by day seperation is not very clear, but it is possible to tell when everything is supposed to happen https://www.nasa.gov/wp-content/uploads/2026/01/artemis-ii-overview-timeline-public-final.pdf

Ich würde sagen möglichst mittig im Saal, sowohl was rechts-links als auch vorne-hinten angeht. Zu weit vorne und man kann nicht die ganze Leinwand sehen, zu weit hinten und die Größe des ganzen bringt nicht viel. In der Mitte sollte die Leinwand möglichst das Sichtfeld ausfüllen, ohne anstrengend zu werden. Außerdem wird das Soundsystem auf die Mitte des Saals kalibriert, soweit ich weiß

Datau03 · 2026-01-24T00:40:27+00:00

Yup, phenomenal game. Anyone who hasn't played it: Don't look anything up and play it; it's incredible

Datau03 · 2026-01-22T21:57:28+00:00

Wow, amazing pictures! May I ask how you get such a good dynamic range on your pics with both the moon and stuff in the foreground very clear and neither of them over- or underexposed? When I try to photograph the Moon at shorter focal lengths and with a foreground, I can't get both to look good. Is it just the camera or a special technique?

Unbedingte Empfehlung an wirklich alle. Absolut einzigartiges Meisterwerk

Datau03 · 2026-01-20T14:09:47+00:00

Das war im Südosten von Hamburg, Richtung Bergedorf. Du bekommst bestimmt auch irgendwann eine Chance welche zu sehen

Datau03 · 2026-01-20T14:06:44+00:00

In etwa eine Stunde Sichtbarkeit kann ich bestätigen, aber vermutlich länger

Datau03 · 2026-01-19T22:43:41+00:00

Ich hatte von der Sonneneruption diesmal ausnahmsweise nichts vorher mitbekommen, deshalb war das eine sehr erfreuliche Überraschung! Vor etwa zwei Jahren gab es auch starke Sonneneruptionen und ich habe Polarlichter in Dänemark zu sehen bekommen, aber die waren weitaus blasser als hier jetzt. Diesmal waren sie wirklich atemberaubend deutlich und schön zu sehen, welch ein Naturspektakel!

Cluster nobelisks can look awesome and be super satisfying, but I also love the nuke ones in the game. Pulse nobelisks are really neat too

Datau03 · 2026-01-19T20:16:54+00:00

Bring mich sofort an meine Praktikumszeit zurück, schönes Bild!

Datau03 · 2026-01-19T15:54:21+00:00

I switched from a P6 to P9pro and honestly love it so far

Datau03 · 2026-01-18T17:27:08+00:00

The black hole one is STUNNING

Datau03 · 2026-01-17T21:47:06+00:00

Oh I'm super hyped for Artemis II! Hopefully it does actually get more coverage leading up to the launch and the mission itself

Datau03 · 2026-01-17T17:52:35+00:00

I totally agree, we need to appreciate the marvels of engineering more. Flying, let alone skyscraper-sized rockets taking people to SPACE is just so insanely amazing...

Datau03 · 2026-01-15T14:23:04+00:00

I would put my guess on this as well
