Thanks to Everyday Astronaut for the coverage and the contagious enthusiasm.
SpaceX will conduct an inflight abort test of Crew Dragon tomorrow morning. As the Falcon 9 reaches max-Q, it will shut off its engines to simulate a worst case failure. This should trigger the Crew Dragon to separate from the rocket and fire its own Super Draco engines to get away from the failing rocket. Once clear, Crew Dragon will pop its parachutes and land gently in the Atlantic. This should be quite a show and is the last major milestone before an actual crewed launch.
Neal Stephenson, commenting on a bunch of stuff.
An economist and a science fiction author discuss cryogenics, mythology, philanthropy, fragmentation, and simulation.
His comments regarding personal freedom in a Martian colony don’t gel with mine. The social system that I imagine in Generation Mars has a great respect for personal freedom.
However, that is tempered by a level of social responsibility that we would likely find unrecognizable here on Earth.
This might be the most dedicated space journalism I’ve ever encountered. I want to say “Bravo!”, but that seems weird.
Ever since human beings have been jamming themselves into little metal canisters and shooting themselves off into space, there has been one thing everyone wants to know: how do you go to the bathroom? Sure, you can read about how it’s done, and for most people that’s enough. But not for me. I wanted to…
Some details on SpaceX’s Mars plan and the issues they are working on.
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.”
This is wild stuff and well worth a full read.
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.
