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 💵) payloadspace.com/why-is-spacex

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.

🚀 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! 🌍✨
