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.

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.

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...

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?

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]
Could be a highly entertaining deckplan.

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.

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.

A galactic war has left the Terran Federation in ruins. Formerly civilized planets have decivilized into barbarism. Space Vikings roam the wreckage, plundering and killing for gain. Lord Lucas Trask of Traskon was no admirer of the Space Vikings, but when murder takes his wife on his wedding day, Trask trades everything he has for his own Space Viking ship and sets out on a galaxy-wide quest for revenge.

Gives nuance to the piracy aspect.

Spaceships: Engine originally designed for NASA's space shuttle is key to low-cost spaceplane
An unpiloted Phantom Express spaceplane climbs toward space on the power of a space shuttle-era main engine in this artist's impression. A smaller rocket attached to the spaceplane will be used to propel satellites into orbit while the winged booster flies back to a runway landing. Initial test flights are planned for 2021.
Boeing and Aerojet Rocketdyne successfully test-fired a space shuttle-era engine 10 times in 10 days, demonstrating the rapid turnaround capability critical to the Phantom Express, a reusable spaceplane, officials said Tuesday. The hydrogen-fueled engine that was tested was originally designed for NASA's space shuttle, which launched for 135 missions.
The Phantom Express, being developed by the Defense Advanced Research Projects Agency (DARPA), stands about 100 feet tall and tips the scales at 240,000 pounds. It will launch vertically using the AR-22 engine, then fly to altitudes of 40 to 60 miles and release an upper stage rocket to boost satellites weighing up to 3,000 pounds into orbit.
The unpiloted winged booster would then autonomously fly back to Earth and land horizontally on a runway like an airplane, ready for inspections and preparations for another launch in as little as one day.
The Air Force and Boeing already operate two small X-37B military spaceplanes that launch atop expendable boosters to carry out classified research in orbit. Like the Phantom Express, they return to runway landings, but they are not equipped with large engines, cannot launch on their own and are not designed to boost satellites into orbit.
"For this program, what we really wanted to do was design a system that was able to fly 10 times in 10 days," said Scott Wierzbanowski, Experimental Spaceplane program manager for DARPA. "This takes off the table the concern that a reusable spaceplane or a reusable booster can inherently be operable."
"We also wanted to design the overall system to be able to insert greater than 3,000 pounds into orbit at a cost of less than $5 million per flight. From our perspective, we figured that was kind of that sweet spot between large space lift and the small up-and-coming expendable systems that will allow us to have true military and commercial capability."
The reusable Phantom Express is designed to launch like a rocket and land like an airplane. A disposable upper stage, carrying a small satellite, is attached to the booster's side. BOEING
The Aerojet Rocketdyne AR-22 main engine was test fired 10 times between June 26 and July 6 at NASA's Stennis Space Center in Mississippi where similar RS-25 main engines are being tested for use in NASA's heavy-lift Space Launch System rocket.
The RS-25 engines are modified versions of surplus "block 2" powerplants left over from the shuttle program, while the Phantom Express engine was made up of older shuttle-heritage hardware that did not meet the more stringent requirements of the SLS system.
Even so, the idea of firing a complex shuttle main engine of any heritage a total of 10 times in 240 hours would have shocked shuttle engineers who devoted long hours to painstaking inspections and servicing between flights.
That's not surprising given a 7,000-pound shuttle engine generated more than 375,000 pounds of thrust at sea level with a hydrogen turbopump that spun at more than 35,000 rpm while generating 71,000 horsepower. The shuttle flew with three such engines while the Phantom Express will use just one.
For the 10 rapid-turnaround test firings, the AR-22 was operated at 100 percent power and throttled to as low as 80 percent during runs lasting at least 100 seconds.
Jeff Haynes, AR-22 program manager for Aerojet Rocketdyne, said the ability to fire the engine 10 times in 10 days was due to the company's long experience across the shuttle and SLS programs, which includes more than a million seconds of cumulative firing time and more than 3,200 starts.
"So we have a lot of data on the inspections that we need to run and how (many) of those have actually resulted in findings," he said. "We did do some boroscope (inspections of turbine blades), we did some torque checks on some of the turbo machinery and we did nozzle leak checks and things like that. But we did not do the typical shuttle profile of pulling the pumps from the engine and doing a detailed inspection."
In addition, he said, "we have significant instrumentation that allows us to know when we are getting into issues and we have redlines that allow us to abort in that scenario. So we felt that running up to those points would be sufficient, and it was successful. So that is the approach we are taking going forward."
Haynes said enough components are available to build a second flight-qualified AR-22 engine and that the test article used in the fast-turnaround tests also could be used for flight.
The program hopes to launch the Phantom Express on its first test flight in 2021. Managers have not yet selected a design for the disposable upper stage or settled on a home base for the spaceplane.

What if we could use the cold darkness of outer space to cool buildings on earth? In this mind-blowing talk, physicist Aaswath Raman details the technology he's developing to harness "night-sky cooling" -- a natural phenomenon where infrared light escapes earth and heads to space, carrying heat along with it -- which could dramatically reduce the energy used by our cooling systems (and the pollution they cause). Learn more about how this approach could lead us towards a future where we intelligently tap into the energy of the universe.
Point the dark side of the spaceship away from the sun, and use the opportunity to panel the other side with solar cells. If an atmosphere is a requirement, blow up fuel condom with air on the dark side.
