Out of the 63 countries with positive organic population growth in the world, 42 are in Africa.

Many of its cities have seen incredible expansion in the past decades, multiplying 10x, 30x or 90x over their size in 1950.

Returning 100 kB of data from Proxima Centauri, when you have only a 1 gram probe with 10 mW of power, is about a BILLION times more difficult than communicating with New Horizons past Pluto.

Here is how the nuclear rocket engine will work:

Well, they lived several levels underground in the previous season, which is more than enough protection if they spend a good % of their time there.

According to the For All Mankind official 2004-2012 timeline, 'Iridium' has become the unobtanium that justifies the space economy, Mars habs above ground are protected by magnetic shielding and there's an interplanetary illegal immigration problem with stowaways:

Quaia is an all-sky quasar map showing over 1.2 million active supermassive black holes detected by the Gaia mission:

It's the catalog with the "largest total volume of the universe mapped".

Carbon has a metastable BC8 form that's tougher than diamond. Its compressive strength may be 30% higher!

However, it would have to be grown as nanocrystals condensing out of liquid carbon at insane 5000K and >1500 GPa conditions.

Xcimer Energy is developing a commercial DT fusion reactor that's like a highly modernized NIF: a 10+ MJ Krypton-Fluoride 248 nm excimer laser (>5% efficiency) as driver and capsules shot by EM gun into a HYLIFE III chamber with molten FLiBe in the walls

Solar sails with a modest lightness ratio of 0.1 can transfer to Venus or Mars and become "quasi-pole-sitters", orbiting indefinitely less than 30° from the planet's poles:

Thinner sails with better lightness ratios can become perfect 0° pole sitters.

I'm quoted several times in there.

It's a known problem for decades.
Which is why US tactics have always relied on breaking air defences down so that strike aircraft can come in unopposed with masses of dumb bombs as early as possible.

Sunlight reflects off the thin spread of gas and dust throughout the Solar System, creating a very fait glow opposite our Sun.
It's called Gegenschein.

CSBA report on the "inadequacy of Western munition stocks" and how the "U.S. military has encountered difficulties meeting its PGM demands in nearly every campaign since their adoption".

It then goes through multiple scenarios to detail how bad it gets.

"In fact, the art of computer programming was essentially invented for SAGE."

Hotspot impact ignition of fusion fuel:

A spherical capsule of DT has a plastic cone inserted into it. When blasted by a laser pulse, a piece of fuel is flung into the sphere's center where its impact generates ignition conditions for the rest of the fuel.

Am I reading this right?
The Type 091, China's first nuclear submarine, spent its first *15* years without any torpedoes installed?
en.wikipedia.org/wiki/Type_09...
And those torpedoes, Yu-3s, took 23 years to develop?

The Harrier from SpaceSolar is a 360° power beaming tech demonstrator, part of their CASSIOPeiA space-based solar power satellite:

It's 0.5m wide and being tested in on the ground, for a 1.7km wide final design operating at GW scale from GEO.

The Yanera-Class Interstellar Cargo Ship.
Debris shield, container stack, glowing radiators... it's got most of the right pieces for a realistic starship!
