Happy Space Science Saturday! Did you know that today Saturn begins its retrograde motion? Normally, Saturn moves eastward against the background of stars, but during retrograde it appears to pivot and move westward through the constellations. This apparent backward motion isn’t because Saturn actually reverses its orbit, but rather because of Earth’s own motion around the Sun. As Earth passes Saturn in its orbit, our changing perspective makes Saturn appear to move backward in the night sky.

Google stops using Pixel phones as reference devices for testing, device trees are missing from Android 16 source code release, making it harder for custom rom devs to port their roms to Pixel devices:
androidauthority.com/google-no
(Google doing their regular "boil the frog" thing... They started with giving Android app devs the option to block sideloading, then they announce to make the development process fully private, only push final releases to AOSP code base, and now this... We desperately need mobile Linux to become an Android replacement! (Although I don't really see that happening any time soon unfortunately.))

Mozilla shuts down the Orbit AI add-on for Firefox, replicates its functionality with built-in features:

(Yay, more AI crap to the browser... More work for LibreWolf devs to remove all that crap...)

Linux Foundation launches FAIR package manager for WordPress, with API replacement and decentralized package management:

Boosting the #ISS would require 120-140 m/s delta-V for a 100-year target #orbit lifetime, in comparison to 57 m/s for a controlled deorbit. Vehicles such as the #SpaceX #Starship are being designed to deliver significant amounts of cargo 📦 to these orbits.While higher altitudes provide a longer theoretical orbital life, the mean time between an impact 💥 event decreases from ~51 years at the current operational altitude to less than four years at a 800km, ~700-year orbit. nasa.gov/faqs-the-internationa

#ElonMusk’s Most Alarming #Power Grab

Can anyone stop his #space-based #internet?

When #Musk’s engineers bundled a batch of prototype #satellites into a rocket’s nose cone 6yrs ago, there were <2k functional satellites in Earth’s #orbit. Many more would soon be on the way: All through the pandemic, & the years since, Musk’s company, #SpaceX, kept launching them. >7k of his satellites now surround #Earth like a cloud of gnats.

If the #cost of launching and operating a #SpaceStation drops 📉 sufficiently, it will become feasible to conduct a number of industrial processes in #orbit. We are not talking about specific experiments here, but of #serial production processes conducted at scale.

To get enough fuel ⛽ into #orbit for a #Mars 🔴 mission would require at least 10 launches of the #SLS rocket, or about $20 billion 💰. Just for the fuel. To use traditional propulsion, one needs to push the boundaries of #reuse ♻️ and heavy lift rockets to extreme limits—which is precisely what #SpaceX is trying to do with its fully reusable launch system arstechnica.com/science/2021/0

Reading about @arthurfox 's album called Orbit and Sam Lawler's (@sundogplanets) discussion of the orbits of Saturn's newly-discovered moons brought up a memory from my childhood.

While driving through Manitoba on the Trans-Canada highway on vacation in 1966, my family passed many signs exhorting us to "Put your trash into Orbit!"

Now it looks like the trash is coming back....from orbit.
