It includes huge variety of machines - in an industry beset with problems!

The helped test the Apollo spacecraft in Earth orbit.
The rocket also carried the Apollo spacecraft to the Skylab space station and to meet a Soviet Soyuz for the Apollo-Soyuz Test Project.
The eight red nozzles are the 8 H-1 that powered the rocket.

If Cities Are Going To Be Packed With Parking Lots, They Should All Have Solar Canopies

Target recently ran a pilot project in California using roof and parking lot solar to power its entire store, including HVAC systems. The system actually produces about 10% more energy than the store can consume, meaning Target can then send the energy back to the grid and receive payment for its power from the local energy company.

@rvaughnmd Real is not by swapping with but actually making , and viable.

Otherwise the ecological results of a isn't better than a aka. []...

Well, that was unexpected.

We have a small leak somewhere in the cooling system, specifically the radiator, that I'm have no end if trouble finding. The engine bay in the motorhome is a nightmare to get around in and the air-conditioning radiator covers the front of the engine radiator completely.

Anyway, while sticking my head into places it didn't fit, we noticed a small longitudinal crack in the serpentine belt. If the belt had been any further around it wouldn't have shown at all. I also noticed that the tensioner indicator was showing that the belt had stretched to the allowed limit.

Fortunately I had a spare belt.

Much struggling later - did I mention the engine bay is a nightmare? - I got the old belt off.

OK, that small crack? It was a separation that ran for about 20 centimetres, and there were a couple of suspect spots elsewhere.

Anyway, new belt installed, a few new cuts and grazes achieved, and sleeping easier.

Oh, that leak? Still can't find it and it didn't show up this afternoon at all. 🤨

This is a cool idea! A different type of 2-stroke engine, but called a
1-stroke, with eight pistons and only four cylinders... :-)

A little confusing, but a really innovative idea!

🇺🇸 #NorthropGrumman's #Antares, the purpose-built launcher of the Station’s #Cygnus cargo resupply #spacecraft, is nearing a #pause in launches. The #rocket’s 🚀 first stages have been manufactured by #Pivdenmash in #Ukraine 🇺🇦.

#SpaceX removed the #Starship 🚀 vehicle from atop the first stage (see 7:45 https://youtu.be/7YqgwBN0_SQ) and set it aside for a #static #fire 🔥 test of all 33 Raptor #rocketengines presently attached to the first stage.
It is possible that this #test could occur within the next week or 10 days 📆 https://arstechnica.com/science/2023/01/spacex-completes-fueling-test-will-now-work-toward-massive-engine-firing-test

has never ignited more than 42% of ’s 33 Raptor at once. When it ignites 🔥 all 33 engines, its maximum could leap to 7590 tons, beating the next in history – the Soviet N1 – by nearly 60% 💪 https://www.teslarati.com/spacex-sets-stage-starship-booster-33-engine-static-fire-2023

test probably 📆 January 30th, 31st, or February 1st
