F-35 Lighting v/s Su-57 Cockpit An esoteric difference between the 2 cockpits is that the F-35 features all-color displays, catering to diverse missions, including low-light and night operations while the Su-57 opts for mostly monochrome displays, tailored for daytime combat.

The N1 rocket, standing 105m tall, was a colossal Soviet rocket with unique NK-15 engines, the largest oxygen-kerosene engines ever built. Each engine produced 1.6 millions lbs of thrust. It had 30 engines in the first stage, 24 in the core.

The N1 rocket used engines known as the NK-15. These engines were designed to operate on a combination of kerosene (RP-1) and liquid oxygen (LOX) propellants. The NK-15 engines were the largest oxygen-kerosene engines ever built and produced approximately 1.6 million pounds of thrust each.

Venera 13's groundbreaking camera provided the first color images of Venus, operating for 2.5 hours in the harsh environment. It had a 170x252 pixel resolution and transmitted images using analog radio waves at 1 kbps.

The data from Venera 13 & 14 produced a confirmed gamma-ray burst event of 1 every 3 days, a factor of 3 better than had been deduced previously from Venera 11 & 12 and Prognoz 7. A total of 44, mostly confirmed, cosmic gamma-ray events were detected between November 1981 and March 1982 by the 2 instruments.

The F-1 engine, biggest ever built by Rocketdyne powered the first stage of Saturn V rocket. It produced a temp of 6k°F (3.3k°C) in the exhaust plume and burned fuel at 3,357 gal/s, which is equivalent to draining an average-sized swimming pool in about 10 seconds.
The F-1 engine was so powerful that it generated a shock wave during launch that was strong enough to damage the rocket and surrounding infrastructure.
