The problem with the SSTO were tech creep and not doing enough ground work to stabilize the tech involved.

It's kinda pointless throwing money down a blackhole, unless you know it will get results at the end.

On the other hand, steady investment in more powerful rockets and propulsion, would reduce the size of the rockets in percentage terms.

Moon Shots are ok when you limit the number of them, set and stick to budgets.

The problem was most of the major systems on for example the venture star project were all moon shots with no clear budgetary restraints.

Spaceships: Aerospike Engines - Why Aren't We Using them Now?

https://www.youtube.com/watch?v=K4zFefh5T-8

Over 50 years ago an engine was designed that overcame the inherent design inefficiencies of bell-shaped rocket nozzles, but despite much research in the 60's, 70's and 90's and was to power the replacement for the Space Shuttle. But 50 years on and it still yet to be flight tested. So why aren't we using Aerospike rocket engines?


Probably easier to vector.

Spaceships: Fusion Energy Is Coming. No, Really. | Answers With Joe

https://www.youtube.com/watch?v=KZm_mpbKX5c

Fusion energy has been about 20 years away for over 60 years now. It's become something of a running joke at this point. But new developments over the last 5-10 years suggest that this time, it could finally be within our reach.

That's what they said twenty years ago "No, really, this time we are close to fusion, honest".


I will believe it when they have a working reactor that generates enough power to make it economically viable and they start building the things for commercial use.

I was curious how Star Wars ships would fare in a virtual wind tunnel! The results were super interesting!


Aerospacedynamics.

Arguably, you could shape deflector screens into the optimum form for flying.

Starships: How do Star Wars Ships Fly? Star Wars Lore Explained

https://www.youtube.com/watch?v=Te3Lqof82tE

Have you ever wondered how ships in the Star Wars universe manage to fly? I'll detail the Star Wars Legends and Canon technology involved in flight in today's Star Wars Lore video!

Today's video looks specifically at star fighters, capital ships and speeders, looking at the Star Wars Legends and Canon lore and technology that allows these vehicles to operate in atmosphere, outserspace, hyperspace and real space. We look at repulsorlifts, sublight drives, hyperdrives, navicomputers, shielding, and lots of other interesting bits of technology.


Repulsorlifts, speeders.

It is all about money. Yes, theoretically we figured it out. But where is the funding? where is the need? The National Aerospace Plane (NASP) was a big deal when I was in college, going to revolutionize intercontinental and sub-orbital flying - never went anywhere because the R&D costs to build were so high that no one wanted to invest in it. Potential market was at best a couple hundred planes - that made the break-even cost per plane very high. too high in the end.

Why is there not a Concorde replacement flying? We have the technology and could do it in about 5 years if needed - but there is no need. The customer may not always be right, but they are always the customer and if there are no customers, there is no company...

Cost benefit London Sydney in two hours. Or Tokyo. Or San Francisco.

It's probably in the black budget, for the Air Force to develop a bomber or weapons platform that can achieve this and go round for a landing back in the continental United States.

Whether Elon Musk, that Virgin guy, and/or Bezos can make it into a commercial venture, who knows?

That would be Branson, he likes sticking his fingers into any publicity rich environment.

I think with Musk it's a question of keeping his attention focussed.

Bezos it might just be a question of the Newton's first law..

Spaceships: How To Create Gravity On The Moon

https://www.youtube.com/watch?v=1P_zAJ1xNos

Today we break down a concept for a surface-based Centrifuge Hab.



The Dutch angle, also known as Dutch tilt, canted angle, or oblique angle, is a type of camera shot where the camera is set at an angle on its roll axis so that the shot is composed with vertical lines at an angle to the side of the frame, or so that the horizon line of the shot is not parallel with the bottom of the camera frame. This produces a viewpoint akin to tilting one's head to the side.[1]
In cinematography, the Dutch angle is one of many cinematic techniques often used to portray psychological uneasiness or tension in the subject being filmed.
Dutch refers to a bastardisation of the word "Deutsch", the German word for "German". It is not related to the Dutch people or language. It originated in the First World War, as Navy blockades made the import (and export) of movies impossible. The German movie scene was part of the expressionist movement, which used the Dutch angle extensively.[2][3]

Spaceships: Hull, Flooring and Gravitational Axis

What you have is a double decker, but the gravity plates are embedded in the central divider, so that gravitation on both decks is one eighty degrees, or completely opposite from each other.

You won't need stairs, since going to the other deck just pivots you through the doorway, where the gravitational plates are angled at a right angle to the the decks.
Could be a highly entertaining deckplan.

Spaceships: Russia's Futuristic Hybrid Nuclear Submarine Aircraft Carrier Concept

https://www.youtube.com/watch?v=Hqm7eJIvVR4

This is a Concept Model and Japan had build similar Submarines in World War 2. Don't believe me Google I-400-class submarine

Japanese Navy had proven this concept back in the World War 2
with their massive Submarine I-400-class submarine

which could carry 2-3 attack fighter bombers with 800 Kg Bombs



I think it has potential as an escort carrier, with hull topside flight deck.

Force Recon returns for a look at Julie Mao's prize Racing Pinnace. The info revealed in this collaboration is canon only to the Expanse TV Continuity, not the ongoing book series.

So does placing thrusters away from the centre of the ship's mass effect maneuverability?

Spaceships: Hulls, Airlocks and Portcullis

Not exactly a hundred percent proof, but embed the outside hatch of the airlock to part of the hull that can revolve, meaning that you'd need to align it in order to get access.
