The New Delhi timelapse actually looks quite depressing: almost all greenery slowly disappearing.

Revisiting time difference, as well as time difference drift, of two station data of 2026-02-11 GPS jamming event, Kosmos 2546 matched perfectly.
While other US classified sats are a bit off, such as Trumpet 1/2/6.

A scientist behind a three-sided mobile lead shield approaches an active 254-tonne cyclotron particle accelerator and using sphere-mounted tongs, prepares to remove an aluminium object made radioactive by 45 MeV alpha-particles bombardment at Argonne National Laboratory, 1955.

@QiaochuYuan Good example of Adversarial Goodhart's Law

[Steven Murdoch @sjmurdoch]

For 19 years, GPS satellites have secretly broadcast a “numbers station” in their public signals. We decoded 12M messages: a 2011 flash where 31 of 32 satellites flipped in hours, “ghost” substrings repeating years apart, and a “TEXT” prefix spreading now. https://t.co/xz3svmqiDa

@_colourmeamused Yes but do either city have a giant 212-story ominous black monolith?

In Microsoft Flight Simulator a bizarrely eldritch, impossibly narrow skyscraper pierces the skies of Melbourne's North like a suburban Australian version of Half-Life 2's Citadel, and I am -all for it-

More wild details from the mid-winter evacuation of an unstable crew member from a Korean base in Antarctica. The guy went into their machine shop and fabricated a 12-inch(!) steel blade before walking around and threatening others on station.

It looks like for the first time, a three-side race broke out between secret Russian, Chinese and US "inspector" satellites 36,000 kilometers from Earth, marking an unprecedented surge of military activities in space.

@Sneakyness @MeganRisdal Sadly no but they did do some interesting stuff.

I had rotating fire hazards, teleportation traps, confusion traps and forced movement traps. Most groups did standard RL, one group did state machine and one enterprising group did an actual genetic algorithm setup.
Made me proud!

GOES-19 caught this amazing view of the exhaust plume from the rocket as it launched from Cape Canaveral.

@GenePark I was vaguely aware of your work, but I think the first time I truly connected was your reporting during the Hawaii false missile alert thing in 2018. You were one of the first to actually talk to people, reacting to it live and providing info.

@PaulTassi @Forbes Good article this. You know what this situation reminds me of? Outriders. That game also approached the live-service genre with a different base take on it, and died due to an eventual lack of normalcore players engaging with it.

Nuclear space ambush

[Sir Humphrey @pinstripedline]

This is the V Force, designed to carry out nuclear strikes on every Russian city with over 100,000 people in it in the event of WW3. How did the UK decide its target plans, and how did it plan to defeat Russia in war?

Long PSL thread on early British nuclear war plans.
