Surveying the current practical and theoretical factors for and against space elevators (including partial elevators—skyhooks!).
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.
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.
If a human civilization beyond Earth ever comes into being, this will be unprecedented in any historical context we might care to invoke—unprecedented in recorded history, unprecedented in human history, unprecedented in terrestrial history, and so on. There have been many human civilizations, but all of these civilizations have arisen and developed on the surface of Earth, so that a civilization that arises or develops away from the surface of Earth would be unprecedented and in this sense absolutely novel even if the institutional structure of a spacefaring civilization were the same as the institutional structure of every civilization that has existed on Earth. For this civilizational novelty, some human novelty is a prerequisite, and this human novelty will be expressed in the mythology that motivates and sustains a spacefaring civilization.
A deep dive into deep time:
Record-keeping technologies introduce an asymmetry into history. First language, then written language, then printed books, and so and so forth. Should human history extend as far into the deep future as it now extends into the deep past, the documentary evidence of past beliefs will be a daunting archive, but in an archive so vast there would be a superfluity of resources to trace the development of human mythologies in a way that we cannot now trace them in our past. We are today creating that archive by inventing the technologies that allow us to preserve an ever-greater proportion of our activities in a way that can be transmitted to our posterity.
Celestial objects ordered by size, covering a scale from one astronaut to the observable universe.
A terrific—and fun!—talk from Zach about site deaths, owning your own content, and the indie web.
Oh, and he really did create MySpaceBook for the talk.
This is quite a beautiful homage to Kubrick’s masterpiece.
