Dr. Phil Metzger posted an epic 48 tweet thread on Twitter explaining why megaconstellations (e.g. SpaceX’s Starlink) are inevitable, as is their eventual demise as better tech comes online.
Looking at the evolution of life, from single celled organisms to bipedal apes rapidly outgrowing the planet, as the exponential growth of information is a novel (to me at least) approach and provides an interesting perspective.
“I would bet that if we find alien civilizations somewhere else in the galaxy, or in a galaxy far, far away, we will discover that they ALL developed megaconstellations right before they got industry off their planets & divorced their information systems from their biosphere.”
Ostensibly about the SpaceX Raptor engine, it’s really so much more. If you’ve ever had a hankerin’ to learn more about rocket engine design, Everyday Astronaut‘s latest video is a great place to start.
I’m not sure there is such a thing as an “ordinary spacecraft”, but there certainly has never been a spacecraft like SpaceX’s BFR. The sheer audacity of someone trying this is balanced by the earnestness of the effort, and the whole process is fascinating to watch unfold. This article investigates some of the challenges SpaceX is facing.
“To be able to launch, refuel in orbit, endure months of flying through space, land on Mars, leave that planet, and safely return to Earth — then do all that over again — the BFR can’t be an ordinary spacecraft.”
