Good Morning, all,
no jars of Vegemite were harmed during the failure of this Aussie rocket launch...
And #RIP Jim Lovell, the only human to ever fly twice to and around the Moon without landing.

Private investors in the #US 
, #EU 
, and #Oceania 
have pumped tens of billions 
into launch vehicle companies—as examples, more than $10B for #BlueOrigin, $1.2B into #RocketLab, $2.4B for #RelativitySpace, $700 million into #Firefly, $500M into #StokeSpace, and $483M into #IsarAerospace. (As an aside, the cost of developing the expendable #Falcon9 was $400M 
) https://payloadspace.com/why-is-spacex-the-master-of-launch
Wir brauchen #ökonomische Bildung (im Sinne progressiver Ökonomik, nicht das, was die #FDP unter Wirtschaft versteht) und ein Verständnis komplexer Systeme in der Breite der Bevölkerung.
Dass ein Friedrich #Merz mit seiner Aussage, wir müssten mehr arbeiten, auf Zustimmung stößt, funktioniert nur, weil Menschen die Zusammenhänge zwischen #Ökonomie, #Verteilungsgerechtigkeit und #Wohlergehen nicht verstehen.
Und weil sie zwar Details ihrer Umwelt verstehen, aber nicht, wie diese in komplexen Systemen interagieren - und was daraus folgt, wenn man an Stellschrauben dreht.
Wenn wir schon in der Schule damit anfingen, wäre das gar kein Problem, denn das ist alles keine #RocketScience ... insbesondere Ökonomie nicht (eine Anhäufung von Quatschbegriffen, hinter denen sehr wenig Wissenschaftlichkeit steckt).
Aus Gründen habe ich mich gestern gefragt: Wenn wir eine gewisse Menge an Flugverkehr zum Mond 
und zurück hätten, und beim Landen und Starten auf dem Mond jeweils Triebwerke benutzt werden müssten , d. h. CO2 oder andere Gase ausgestoßen würden - wie lange würde es wohl dauern, bis auf dem Mond 1. ein Klima und 2. ein Klimawandel entsteht? 
Das ist eine ernstgemeinte Frage.

Taking a break from reality to watch high-speed film launches of the Space Shuttle.
Stepping back in time to a world when NASA was sending humans into space using a lot less computing power than your new TV.
It's a very calming video, watching thousands of pounds of fuel ignited as the shuttle and it's boosters slowly rise into the sky. 45mins of rockets on fire.
Very special.
We've arranged a #society based on #science and #technology, in which nobody understands anything about science and technology. And this combustible mixture of #ignorance 
and #power 
, sooner or later, is going to blow up in our faces. Who is running the science and technology in a #democracy 
if the people don't know anything about it ? https://en.wikiquote.org/wiki/Carl_Sagan#Quotes
Rocket Science & Autism (yes, I can and so can you)
When I say I love learning, I mean it. From neuroscience to cuneiform, my autistic brain thrives on deep dives into complex subjects. That's why I’m currently taking "Rocket Science for Everyone" at Yale University via Coursera.
Here are six fascinating facts I learned about orbital mechanics—yes, the physics that keeps satellites in space! 
The world's first liquid-fueled #rocket was successfully launched on 
March 16, 1926 https://www.openstreetmap.org/node/7717931893

The test cargo.
A single jar of Vegemite.
I bet it is not even the "vegan" kind.
Bugger hey, bit risky, a whole Jar !
Good on em .
May Max Q Smile On You.

Following lengthy delays 
, #Ariane6 blasted off on July 9 and successfully carried out a series of trials. But the mission ended with the launcher coasting in orbit without releasing its final batch of payloads. The #Arianespace CEO said the failure had been traced to a #software flaw that would be repaired before the next launch. https://www.reuters.com/technology/space/ariane-6-set-new-launch-this-year-after-software-flaw-identified-2024-09-16
#FusionPropulsion offers 1000 times the power of conventional #IonThrusters currently used in orbit. The vacuum environment and extremely cold 
temperatures of space provide an ideal setting for fusion propulsion * https://orbitaltoday.com/2023/07/14/interplanetary-travel-to-become-faster-through-nuclear-fusion/
The #FireStar Drive begins a fusion process by adding #boron into the thruster exhaust. The base thruster generates high-speed protons through the ionization of water vapor. These protons collide with the nucleus of a boron atom, which starts the fusion reaction. The technique produced ionizing radiation and increased the base propulsion unit’s thrust by 50%
