One reason they encourage parking at the HiPort could be to minimize any possible impact.

Though it has me now thinking, exactly what happens directly under a vehicular gravitic motor, spaceship or otherwise? If it's a two hundred kay battleship, perhaps increased local gravity field.

1) Nothing unless you want the the GM to put reproductive health warnings on grav belts.

2) If using non-magical lift such as rotors or wings, the weight of the vehicle is supported by the ground as normal, but over a wider area as the air column spreads out. Basically if you have a closed van full of pidgeons, it weighs the same if they're roosting or flying. You will see variations as they flap, but it will average out the same.

 

[Condottiere]

Grav motors utilize technology that somehow interacts directly with the planetary gravitational field, so you have to wonder if it alters local gravity, specifically that underneath it, compared to manoeuvre thrusters that probably in the Mongosian variant pushers that recreate gravitational thrust independent of external gravitational wells.

Starwarships: Pasture or pasteurization, and Why Wasn't Orbital Bombardment Used More Often?

Orbital Bombardment is great! You don't have to risk any of your troops. You don't even need to step foot on a terrible planet like Kamino or Malachor or Philadelphia. Or so I thought... after doing a bit of research I've come to conclusion that orbital bombardment is not always the best choice.

Starwarships: The IMPERIAL Nebulon-B Frigate (Fan design)

The Nebulon-B has long been considered a Rebel vessel, but canonically this frigate was originally an Imperial vessel. I took on the challenge of creating what that might have looked like.

It's an odd duck.

I always thought the design was optimized for modularization, which allowed a mix and match construction or easy reconfiguration.

The proposed stripped down aesthetic would fit that of the Why Fighters.

Spaceships: Why will Starship only have 2 rear fins?!

We’re less than a week away from this year’s Starship update from Elon Musk. And before the party gets started, we’re already catching some major changes happening before our eyes.

The most obvious change is the fact that Starship only has two finny / flappy / airbrakey things instead of three. Now the previous version touted just last year at the DearMoon event showed Starship sporting 3 fins that were also its landing legs.

So now that we’re seeing only two, the question has come up, why? Why two?

So today we’re going to do a really quick rundown on why two might be better than three, show you some potential problems with three fins, and then we’ll show you exactly how they’ll control their reentry and landing with just 2 rear fins.

1. Giant airbrakes or body flaps.

2. Weight, though not necessarily volume.

3. Landing legs; would need to be pre stressed. Or have springs.

4. For a tail sitter, you probably would prefer a vertical descent.

5. The belly flop seems a viable solution.

The Biefeld–Brown effect is an electrical phenomenon that produces an ionic wind that transfers its momentum to surrounding neutral particles. It describes a force observed on an asymmetric capacitor when high voltage is applied to the capacitor's electrodes.[1] Once suitably charged up to high DC potentials, a thrust at the negative terminal, pushing it away from the positive terminal, is generated.[2] The effect was named by inventor Thomas Townsend Brown who claimed that he did a series of experiments with professor of astronomy Paul Alfred Biefeld, a former teacher of Brown whom Brown claimed was his mentor and co-experimenter at Denison University in Ohio.[3][4]
The use of an asymmetric capacitor, with the negative electrode being larger than the positive electrode, allowed for more thrust to be produced in the direction from the low-flux to the high-flux region compared to a conventional capacitor.[2] These asymmetric capacitors became known as Asymmetrical Capacitor Thrusters (ACT).[5] The Biefeld–Brown effect can be observed in ionocrafts and lifters, which utilize the effect to produce thrust in the air without requiring any combustion or moving parts.[1]
In his 1960 patent titled "Electrokinetic Apparatus," Brown refers to electrokinesis to describe the Biefeld–Brown effect, linking the phenomenon to the field of electrohydrodynamics (EHD).[1][2] Brown also believed the Biefeld–Brown effect could produce an anti-gravity force, referred to as "electrogravitics" based on it being an electricity/gravity phenomenon.[6][7] However, there is little evidence that supports Brown's claim on the effect's anti-gravity properties.[8]

Spaceships: Hulls and This Metal Asteroid Could Reveal Secrets About Earth’s Core | Countdown to Launch

NASA and Arizona State University plan to send an orbiter to the Psyche asteroid, which is believed to be made mostly out of metal. This mission could be the key to understanding the inside of Earth's core.

Between Mars and Jupiter, you can find Psyche, one of the only asteroids that scientists believe might be made mostly of metal and researchers from NASA and and Arizona State University will be sending an orbiter to the asteroid for the very first time.

Exploring Psyche’s terrain could be our only key to understanding what the inside of Earth’s core could be like.

Visiting asteroids isn’t new to space exploration with Vesta, Ceres, Ryugu, and Bennu being some of the most recent mission destinations.

And asteroids, for the most part, have been all the same; usually rocky, airless drifting through the cosmos as leftover debris from a chaotic beginning.

But Psyche is different.

“We’re pretty sure that it’s largely made of iron-nickel metal. And there are very, very few asteroids out in the asteroid belt that we think are made of metal or largely of metal,” Lindy Elkins-Tanton, Principal Investigator of the NASA Psyche mission, told Seeker

Researchers suspect Psyche is an exposed core of a protoplanet, which is a planet in its early formation stages and it’s most likely that the asteroid lost its rocky exterior during violent collisions in the beginning of our solar system’s evolution...at least, that’s what scientists’ best assumptions are.

And no one really knows what Psyche looks like beyond a speck of light, and so the 2022 Psyche mission will include sending back camera images of the asteroid so we can take a look at what a metallic body like this looks like.

Find out more about this metallic asteroid and how the team of researchers plans to explore its terrain on this episode of Countdown to Launch.

MISSION TO A METAL WORLD: Psyche
https://www.jpl.nasa.gov/missions/psy...
"Because we cannot see or measure Earth's core directly, Psyche offers a unique window into the violent history of collisions and accretion that created terrestrial planets. The mission is led by Arizona State University. NASA's Jet Propulsion Laboratory is responsible for mission management, operations and navigation."

16 Psyche
https://solarsystem.nasa.gov/asteroid...
"Unlike most other asteroids that are rocky or icy bodies, scientists think the M-type (metallic) asteroid 16 Psyche is comprised mostly of metallic iron and nickel similar to Earth’s core. Scientists wonder whether Psyche could be an exposed core of an early planet, maybe as large as Mars, that lost its rocky outer layers due to a number of violent collisions billions of years ago."

Or you could just install a zero point one manoeuvre drive, at a default one thousandth of the volume.


Lightsail 2 Sails On Sunlight At Last

Lightsail 2 was launched in June as part of the STP-2 launch on Falcon Heavy, after a few weeks of checking systems out it deployed its solar sail and began attempting to raise its orbit. Earlier this week the Planetary Society declared success - raising the apogee of the orbit higher, even if the orbit on average got lower due to atmospheric drag.

Spaceships: Engineering and Superconductor material could be cool for quantum cats by NICK FARRELL on 11 OCTOBER 2019

B-Bi2Pd needs no magnetic fields

Researchers from the Johns Hopkins University describe a superconducting material, B-Bi2Pd, that naturally exists in a quantum state without the additional influence of magnetic fields usually needed for such an effect.

The authors write that the low-maintenance, stability of this material makes it a perfect candidate for designing quantum systems.

The research will be published today in the journal Science by physicists from Johns Hopkins University.

The paper's first author, Yufan Li, said in a press release: "We've found that a certain superconducting material contains special properties that could be the building blocks for technology of the future. A ring of B-Bi2Pd already exists in the ideal state and doesn't require any additional modifications to work. This could be a game changer."

What makes this superconducting material special is the unique state it occupies as its ground state, or when no other forces are being exerted on it. While other superconducting materials can be forced to maintain a quantum state using external magnetic fields or energy-sustaining "quantum spin liquid".

The researchers found that this material naturally exists in a quantum superposition, in which current can simultaneously flow clockwise and counter-clockwise in a ring of the material. This discovery is the realisation of a prediction made by physicists in the 80s.

The authors write that this property makes it an ideal candidate for quantum systems. However, that does not mean the technology will get picked up, or that if it does we will remember this story.

Apply a current and create a gravitational field.

Reverse polarity and create an anti gravitational field.

Or beams.

Spaceships: Runaway Train or The Spiralling Dutchman/b]

1. So what you do is you boost the space passenger liner to one gee and then let it drift.

2. You use smaller jets to correct the course, as well as a little additional acceleration if velocity is lost.

3. Shuttles match velocity and dock with the passenger liner, allowing their freight and passengers to benefit from Newton's first law.

4. A constant and consistent exchange of planetary shuttles as they separate and dock as the passenger liner passes a planetary body should even out speed.

Starwarships: Star Wars Ships | Why Did The Empire WEAKEN the Victory 2-class Star Destroyer

The Victory 2-class Star Destroyer is an insult to the Victory-1 missile barrage heritage. But for good reason. See a complete Star Wars ship comparison to the Victory-1 class, Imperial class Star Destroyer, the Venator and many other Star Wars capital ships. This complete breakdown of the Victory-2 will have you appreciating how the Empire had to adapt to the new Rebel Alliance threat.

Matter Beam's analysis of the Epstein drive from the Expanse

 

[Condottiere]

I've always speculated we could dump the heat in the propulsion drives.

As I understand the issue with heat dumps, is that the heat has to be transferred to some physical object, even if it's only in ionic form.

This would require actual fuel to be expended, as compared to some form of gravitic wave form that the gravitic motors would modulate.

You supercharge the fuel with the heat, even if it actually creates no perceivable additional thrust, if only to remove said heat from the spaceship.

On the other hand, if the heat could be dumped into a magnetic field and self ignite, we might only need a stripped down fusion power plant.

 

[Condottiere]

Ammonia is about eight times as dense!

If that's the case, and it can easily be converted to a form of hydrogen digestible by the spaceship power plant, the hyperspace drives, and/or the fusion rockets, time for Traveller 2.0.

 

[Anonymous]

I liked the miniatures from attack vector (a space tabletop game with full 3d realistic movement). They have a Traveller variant.

Being a mostly hard scifi game, their view was that in vacuum you can only dissipate heat via radiation, so their reactors were covered in heat sink vents. It's the big spiky ball at the right hand end of the ship, separated from the ship itself by a metal cantilever (ladder?) frame. Those particular ones are space russians. Also visible at the other end of the ladder are the fuel tanks. In front of that is a cyclinder for the ship proper, covered in gun turrets of course.

 

[Condottiere]

I wonder if spinning them like a ventilator would help.

 

[Anonymous]

not in vacuum you can't spin like a ventilator for increased cooling

But attack vector ships can rotate freely independent of direction on of travel so you kind of boost past someone while pivoting to keep your batteries bearing.

As it's full 3d with up and down, it needs some effort to play, but it is well worth it if you want 3d movement that conforms to Newton's laws.

 

[Condottiere]

Or, you pump heated water vapour in front of the nose, let it fountain out, and have a scoop in the rear to collect it.

Rinse and repeat.
