One thing a lot of people get wrong is that the idea that the shuttle was in orbit when it dropped the tank. When the engines shut down the tank and the shuttle were on the same orbital trajectory that intersected the atmosphere. This meant the shuttle had to boost itself at the highest point of its orbit using the OMS to avoiding reentering the atmosphere with the tank.

[@mikekopack6441]

And that was mostly so the tank would reenter and break up, rather than leave space junk in orbit.

[@u12uNiiGuNx]

Yup but at that point they’re 99% of the way there so it doesn’t take much energy to to increase the periapsis.

The final push into orbit is not from the main engines, but from the orbital maneuvering system (OMS). If the orbiter was in orbit at main engine cutoff (MECO) then the jettisoned tank would remain in orbit rather than burning up in the atmosphere.

@ 11:25 The Chandra/IUS stack was not the maximum limit for the Shuttle fleet in general, only for OV-102 Columbia, which was 3.6 metric tons heavier than her newer sisters, and it was Columbia that flew that mission since she was the only orbiter at the time that had not been outfitted with an external airlock and therefore was capable of holding the 56 foot (17 meter) stack in her payload bay. As it was, the mission was only possible for Columbia because of the recent introduction of the super lightweight aluminum-lithium external tanks, which shaved off 8,000 lbs (3.6 mt) in mass from the overall Shuttle launch stack and therefore added a roughly equivalent amount to the payload mass to orbit.

[@TheHatManCole]

Could you do a video on the insane engineering of the LM? I find this ship so meaningful because it is the only craft ever designed to carry humans to fly only in 0 atmosphere conditions, which is why it looks so weird. I think this is very meaningful to engineering history because the fact that we needed a ship to carry people in 0 atmosphere conditions says a lot about how far we have come as a species.

The Shuttle was truly a feat of engineering. Kudos to the crew involved in telling a great piece of history.

[@00andrew000]

And kudos to the engineers who created it!

[@everettlwilliamsii3740]

The shuttle should never have been built as it was to be a giraffe when a horse was needed. It was the throwing of 250k lbs into orbit for a max payload of around 20k lbs...and then hauling most of that 250k lbs back down to Earth. What a waste! If a capsule was hoisted to orbit on top of a lightweight container, cutting off the weight of wings and wheels, the shuttle stack could have boosted well over 100k lbs to orbit on each launch as well as the external tank for construction materials. The presence of a capsule would have made the whole thing safer while reducing the wasted fuel and risk. With that kind of payload, the entire space station could have been lifted in 3-4 payloads and something larger than the Hubble could be panning the universe at the moment, with far more durable pointing elements and a greater capacity to restore for repeated images. And there is so much more that we could have done with those 133 launches, not to mention that we would probably have had 14 less casualties. 90% of weight to orbit as useful payloads as opposed to shuttle's 10% seems the brighter way to go. The occasional need for down-mass beyond the capabilities of the capsule could be met by putting a lifting body in the freight container. It could easily carry more down-mass than the shuttle and could be landed remotely with little to no risk to personnel. The shuttle was far more complex than it had to be, contributing massively to the cost and destroying the rapid reusability, making it mostly refurbishable at huge expense.

[@neoanderson7]

@@everettlwilliamsii3740 considering what they had to deal with in regards to the requirements from both the engineers and the military, they did what they could. It still plays a major role in our history. For what came out of the entire project, I still think they did very well and showed what could be done when so many requirements had to be met.

[@SanctuaryLife]

As a child of the 80s (born 1978) this is the ship I grew up with and got to watch every 6 months or so on TV. Will forever hold a special place in my heart. It was a worthy heavy lift unit albeit a risky one and it's nice to see Starship coming through to pick up where it left off. I can only hope the 2020s will consist of Starship and the most reliable heavy lift we've ever seen.

[@Simple_But_Expensive]

In the early shutlle program, someone (I think it was David Brin), proposed not ejecting the main fuel tank until it was in orbit. By putting a hatch on it, you would have a large pressure tight enclosure ready for retrofitting into a space station. By attaching multiple tanks with cables and spinning them, a rotating wheel type station was possible. No idea if it was feasible.

[@wytfish4855]

if my simple understanding is up to par, even assuming that the fuel tank is a simple hollow cylinder, the propellants are kinda hazardous after all, sensors and scrubbing equipment required to make it safe for activities would add extra weight, which itself is already a very scarce commodity for space flights.

[@Simple_But_Expensive]

@@wytfish4855 Liquid hydrogen and liquid oxygen. The idea was to have an excess of oxygen. The followup mission would install a fuel cell to provide power. The fuel cell would combine hydrogen and oxygen to create water. The followup mission would also bring liquid nitrogen to combine with the oxygen to create air (79% nitrogen, 21% oxygen). The power from the fuel cell would be used to heat the nitrogen/oxygen mixture until it turned into gas. The remaining liquid oxygen and nitrogen would be stored in tanks strapped to the outside as reserve. The new tank design would have one end of the oxygen tank and external shell flanged for removal and installation of internal parts fllowed by an airlock module. The tanks would be tethered to each other and spun for gravity simulation. Spinning in Earth’s magnetic field would generate electricity long term. Orbital manuevering would be provided by electron guns. NASA took one look, realized they could make it work if they Apollo level support, decided it wasn’t worth the risk, and shelved the idea.
