Spring always comes.

How do we keep ourselves and our spirits (and our comrades, and their spirits) fed and warm until it does?

What will we be prepared to plant when the ground thaws?

This paper started with a plot showing the density of satellites in orbit vs. altitude that Aaron Boley (professor at UBC) made. I knew this was probably bad, but what does 10^(-7) objects per cubic km really even mean when everything is flying around at 7km […]

Two incredibly talented students led the project. We figured out a much less hand-wavy analytical way to calculate close approach rates using real data from public catalogues. And then we also ran n-body simulations to double check. They agree very well! And […]

Starlink themselves report an average of 1 collision avoidance maneuver every 2 minutes between Dec 2024-May 2025. So that's another (terrifying) double check on this calculation. Starlink themselves report an average of 1 collision avoidance maneuver every 2 minutes. So that's another […]

We also did this calculation for the catalogue of satellites, trackable debris, and rocket bodies from 2018, before megaconstellations, showing just how much less safe megaconstellations like Starlink have made orbit.

The densest part of orbit in 2018 had a […]

The CRASH Clock uses the current density in altitude bins (averaged over eccentric orbits) of satellites, rocket bodies, and tracked debris, assuming typical cross sections for each type and orbital speeds. This calculation tells us how long to a collision if all orbital maneuvers were to […]

The senate is considering a bill to allow 16 and 17 year olds to vote in Canada. They can work and pay taxes, they can drive, they're expected to start considering their future careers and make decisions to further them.

Have your say on the bill before the Senate:
