Speaking of freelancing, I am now formally a freelance writer, with experience in long and short format video scripts, research into scientific/ economic/ social/ medical topics, game and physical product development and more. Contact me for work! Here's a (public) CV:

These are structures on a scale of 100,000 km moving at 1200x the speed of sound:

The award-winning documentary that Sen. Adam Schiff demanded to have removed from Amazon Prime shows how metabolic and other natural cancer treatments work. "We're not giving cancer an opportunity to detour . . . to escape down one of its usual [biochemical] pathways."

Design study of a Nuclear-Electric probe for outer solar system missions, based on an upgraded 17.5 kWe Kilopower reactor and NEXT-C ion thrusters: https://t.co/gEHT3XTdqm Average acceleration should be an anemic 8 *microgee* and it only delivers 10.3 km/s deltaV total.

Combined, the 33 Raptor engines here have a power of 126 GW. That's comparable to the output of all the natural gas powerplants in the US! https://t.co/X6SQGAyJYZ

The S-1D, a proposed Saturn V upgrade that gave it an Atlas-style 1.5 stage that discarded 4x F-1 engines during its ascent. #space #art by @brickmack https://t.co/Jhba6AVgHI

Firing a rocket or scramjet-boosted shell out of a 16 inch naval gun to turn it into an anti-satellite weapon: https://t.co/CsqXkvR5ZA Muzzle velocity is Mach 4.5, raised further until it can reach altitudes of 500-900 km, perhaps with the help of a 40g+ pop-up maneuver.

JWST's Near-Infrared Spectrograph is able to pick up the faint plasma torus surrounding Saturn, created by volatiles ejected from Enceladus: https://t.co/1LPsA1K2On And in that torus, it detects water, confirming again the presence of vast underground oceans.

The A-6A Intruder surrounded by the ordinance it could carry. These range from small 8.4 kg FFAR rockets to 907 kg Mk 84 bombs to (hidden in bags) nuclear weapons. It could nearly match the maximum payload of a B-29 Superfortress.

Pure delta: the A-12 Avenger II stealth attacker meant to replace the A-6 aboard US carriers. It would have had similar range and speed but much reduced payload (2.3 tons vs 8.2 tons). #art by WaveLabs https://t.co/FPpcvYOeWf

Mercury's chaotic terrain features are not the result of planet-wide impact shockwaves but the much later evaporation of a volatile-rich underground layer, which created voids into which the surface collapsed: https://t.co/jQypwWJfN4 There must have been impressive geysers 3.9GYa

Mankin's later space-based solar power concepts included this SolarDisc: https://t.co/y5QGnpY9TL It's a multi-km wide disc of thin-film PV generating 5 GW that it beams down as 5.8 GHz microwaves to a number of 4-8 km wide ground receivers depending on electrical needs.

If you want to show off your afterburning engines, do it at night! XB-1 footage from @boomaero: https://t.co/wis9oigPlL

Fantastic gas giant renders in very pretty colours. #space #art by Isaiah. https://t.co/6uoKKazshx

This view, but taken out of a window by an astronaut's amateur camera.

Only the cleanest rockets get to launch. *scrub* *scrub* *scrub*

The North American NAC-60 was essentially a scaled-up XB-70 Valkyrie, with the same engines and canards, but used as a supersonic passenger jet. It would reach Mach 2.65 with 187 passengers onboard, crossing >6000 km in just over 2h.

Cutaway of the SEALION boat operated by SEALS/Special Boat Units: By @CovertShores https://t.co/OtgjxjP1S5 It's a fully enclosed hull with stealth features, and submerge itself to become very hard to spot.
