#ElonMusk’s Most Alarming #Power Grab

Can anyone stop his #space-based #internet?

by Ross Andersen

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. Some specialized industrial processes can be done more efficiently in space 🌌, because of the absence of #gravity, particularly some #biotech applications with tangible applications on Earth aerotime.aero/articles/how-sta

It didn't get much coverage, but shortly before invading #Ukraine in 2022, #Russia launched a #military #satellite into #orbit which some feared was part of a #nuclear anti-satellite #weapon program in violation of the #OuterSpaceTreaty

While terrifying, there is some good news to report:

"#Russian satellite linked to #space weapon programme appears to malfunction in orbit"

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

#Space 🌌 is a far more logical, sensible place to do #fusion, because that’s where it wants to happen anyway. In 📆 2027, we’re going to send a small part of #Sunbird in #orbit. The first #functional Sunbird will be ready four to five years later. Sunbird could deliver #cargo to #Mars 🔴 in under six months edition.cnn.com/science/nuclea

CNN · Nuclear-powered rocket concept could cut journey time to Mars in halfBy Jacopo Prisco

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.

The #3Dprinted prototype was able to generate thrust more #efficiently than larger, more expensive #chemical rockets and outperformed existing droplet #electrospray engines. It can be produced rapidly and for a fraction of the #cost 💵 of traditional thrusters and even be fully made in #orbit 🌌 news.mit.edu/2025/mit-engineer
