Surveying the current practical and theoretical factors for and against space elevators (including partial elevators—skyhooks!).
I do want to recognize that the Safari/WebKit team are working hard, and I do desperately want them to succeed! Chromium’s domination is bad for everybody, and building a popular browser that’s focused on privacy & security, as they appear to be trying to do, is a fantastic goal. That does not mean their current approach deserves our blind support.
I’m sure the Safari team are working on the issues below already, and I think it’s likely that the problems fundamentally derive from management decisions about company priorities rather than the team themselves.
Beautifully restored high-resolution photographs of the Earth taken by Apollo astronauts.
Your grandmother is not just a starship, she’s a highly individual starship with her own goals and needs!
League tables for the game of probe-throwing currently underway in our solar system.
The league covers expensive hardware lob matches held between planets in the Solar System. Two dwarf planets have recently been admitted to the league and lost their first matches against league champions Team Earth.
A lovely visualisation of asteroids in our solar system.
An Orbital Ring System as an alternative to a space elevator.
Representing nothing short of the most ambitious project in the history of space exploration and exploitation, the Orbital Ring System is more or less what you would imagine it to be, a gargantuan metal ring high above the Earth, spanning the length of its 40,000 kilometer-long diameter.
I too am a member of The British Interplanetary Society and I too recommend it.

This is an epic deep dive into the 1984 sequel to 2001: A Space Odyssey.
For all its flaws, I have a soft spot for this film (and book).
A meditative essay on the nature of time.
The simultaneous dimming of Betelgeuse and the global emergence of COVID-19 were curiously rhyming phenomena: disruptions of familiar, reassuring rhythms, both with latent apocalyptic potential.
Time and distance are out of place here.
We will have left a world governed by Chronos, the Greek god of linear, global, objective time measured by clocks, and arrived into a world governed by Kairos, the Greek god of nonlinear, local, subjective time, measured by the ebb and flow of local patterns of risk and opportunity. The Virus Quadrille is not just the concluding act of pandemic time but the opening act of an entire extended future.
Looking at COVID-19 through the lens of pace layers.
…a citizen could actually play a part that was as important as a vaccine, but instead of preventing transmission of the virus into another cell at the ACE receptor level, it’s preventing transmission of the virus at the social network level. So we’re actually adopting a kind of behavioral vaccine policy, by voluntarily or otherwise self-isolating.
Beautiful high resolution posters of our planetary neighbourhood.
It was fifty years ago this weekend. Follow along here, timeshifted by half a century.
The return of NASA’s iconic “worm” logo (for some missions).
The best podcast of last year is back for another season, this time on the Apollo 13 mission.
