Some details on SpaceX’s Mars plan and the issues they are working on.
Ars Technica Outgrowing the planet is not a bad thing
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.

Where the rules haven’t been written
A brief but inspiring interview with Robert Zubrin:

Moon or bust?
Here’s the most thorough evaluation of the the latest push for the Moon that I’ve found. The TL;DR is that the winds are all over the place. This push is likely to fail. But we should root for it anyway because it’s shaking things up.
An impressive stack
Wowza! He’s talking about an Orion atop a ULA second stage atop a SpaceX Falcon Heavy. We live in interesting times.
FJ-rover
I had a Hilux for years that would take me anywhere I pointed it. For as long as I can remember, I’ve wanted an FJ40. I’m not a big fan of the modern FJ. But this…when can I get one?
