There are other alternatives:
1. Include only a ten percent fuel tank.
2. Build two separate ten percent fuel tanks.
3. Leave the twenty percent fuel tank half empty.
Of course, power plant fuel is in a separate tank.

Starships: Accommodations and 7 Weird Rules on Cruise Ships and Why They Exist
Don’t ask the captain to shake your hand and if you are too young you might be blocked from cruising. We're talking about the 7 weird rules on cruise ships and why they exist!

Traveller High Guard would default at seven.
Unless it has a nuclear warhead, in which case six.

Not that it can reconcile with the fact that reactionary rockets default at factor three at technological level seven, and non existent at six.

Spaceships: Hull, Armour Plating, and Are We Too Late To Avoid Kessler Syndrome?
Space junk and debris is starting to be a problem around Low Earth Orbit (LEO) according to the ESA and JAXA. Exactly how much is up there? And are we soon approaching the threshold of Kessler Syndrome?
https://www.youtube.com/watch?v=MmVW8f31vI8
Does default hull protect against these types of collisions?
If not, what factor armour plating do we need?

1. Low thrust and high efficiency.
2. High thrust and low effiiency.
3. Hundred kilowatts? Peanuts.
4. However, I believe gravity acceleration is nine point eight metres per second squared, so the maths seems a little off.

1. Bubble of distorted spacetime.
2. Remember, it's space that's expanding, not your midriff.
3. Negative energy may be politically incorrect; let's call it exotic particles.
4 . Dividing by zero.
I think we've just discovered the formula for jump space transition.
5. One power point equals half a gigawatt; so that's fifty megawatts per tonne per parsec.
6. Positive energy would be supplied by electricity, hydrogen converted exotic particles would provide the negative energy.

1. Trendsetter for super yachts.
2. Love boat.
3. Maximum passenger space, cramped crew quarters.
4. Toilet paper shortage court martial offence with no defence; likely for all sanitary supplies.
5. Soft shoes and low voices to optimize sound proofing.
6. Everything is shined, spicked and spanned.
7. Multi role.
8. Should be engineering compatible to either other warships and/or current commercial vessels.
9. Subsector dukes should have one.
Considering the high passage prices, you'd expect them all to have yacht standards.

Spaceships: Hulls and Why does Starship belly flop?
Why is SpaceX doing the belly flop with Starship? Why are they going from belly flopping and then flipping to tail down and why are they doing that so close to the ground? Why don’t they just start the flip maneuver earlier and ensure there’s enough time to make corrections if something goes wrong?
We’ll also dive into the different options SpaceX has with lighting engines, how many engines can they run and at what altitude? Is running on more engines better? And can parachutes be a back up if the engines don’t work?
And of course, we’ll answer the ultimate question. Will this ever be safe enough for humans? Can you even survive the G forces?! Should SpaceX just give up on the belly flop and do a landing more like a Falcon 9, which has proven to be highly successful?
So today we’ll look at the wonders of terminal velocity, gravity drag, thrust to weight ratios, and engine throttling to see why SpaceX is trying this belly flop maneuver and see if we think it’s worth it or if SpaceX should go back to the drawing board.
00:00 - Intro
03:15 - How The Flip Maneuver Works
06:00 - Why Belly Flop / Terminal Velocity
13:15 - Thrust to Weight Ratios / Engine Throttling
21:00 - Gravity Loss / Gravity Drag
26:25 - Why Flip So Late
33:45 - Can This Be Safe?
39:30 - Conclusion
https://www.youtube.com/watch?v=BqJ5bKuApbs
1. Air is a fluid.
2. Adjustable flaps.
3. Minimal landing burn.
4. Okay, so clueless to thrust to weight ratio in Traveller.
5. Volume unlikely to affect throttling, unless using external fuel bladder.
6. Gravity eats efficiency.
7. Suicide burn; how about kamikaze krash?
8. Instead of reactionary rockets, maybe manoeuvre drives with factor one, or subfactor one.
9. Overclock the drives for a faction of a turn.
10. Seems less taxing on human anatomy than normal landing.
11. Apparently, might add landing faculties to facilitate safer landing.

Spaceships: Engineering and Satellites
SpaceX today was granted permission to use a lower orbit for Starlink satellites, as regulators agreed with SpaceX that the change will improve broadband speed and latency while making it easier to minimize orbital debris. In granting SpaceX's request, the Federal Communications Commission dismissed opposition from Viasat, Hughes, Dish Network, OneWeb, the Amazon subsidiary known as Kuiper, and other satellite companies that claimed the change would cause too much interference with other systems.
In 2018, SpaceX received FCC approval to launch 4,425 broadband satellites at orbits of 1,110 km to 1,325 km. Today's FCC order granting SpaceX's license-change request lowers the altitude for 2,814 of the satellites, letting them orbit in the 540-570 km range. Today's FCC order will also let SpaceX use a lower elevation angle for antennas on user terminals and gateway Earth stations.
"Based on our review, we agree with SpaceX that the modification will improve the experience for users of the SpaceX service, including in often-underserved polar regions," the FCC order said. "We conclude that the lower elevation angle of its earth station antennas and lower altitude of its satellites enables a better user experience by improving speeds and latency."
The FCC order also said, "a number of the satellites being deployed pursuant to this modification are satellites orbiting at high inclinations, which are uniquely able to provide improved service to higher latitude regions." As for the license change's impact on orbital debris, the FCC said that "deployment to a lower altitude guarantees removal of satellites from orbit within a relatively short period of time, and consequently has beneficial effects with respect to orbital debris mitigation."
Many satellites at different altitudes
The number of Starlink satellites from the first batch approved in March 2018 has since been reduced from 4,425 to 4,408, but SpaceX separately was granted permission in November 2018 to launch another 7,518 satellites at even lower altitudes of 335 km to 346 km. The space company is also seeking permission for 30,000 more satellites at altitudes ranging from 328 km to 614 km.
Besides what we've already mentioned, today's FCC order gives SpaceX "authority to conduct launch and early orbit phase (LEOP) operations and payload testing during orbit-raising and deorbit of its satellites."
"Our action will allow SpaceX to implement safety-focused changes to the deployment of its satellite constellation to deliver broadband service throughout the United States, including to those who live in areas underserved or unserved by terrestrial systems," the FCC said.

Starwarships: Hulls and Capital Ship Battle Video
Here is the capital ship battle video used as part of the composer selection process for Elite: Dangerous. The video contains the music created for the pitch by the winning composer Erasmus Talbot.
The video also helped us develop other aspects of the game such as ship materials, GUI layout and special effects. Look out for David Braben's next dev diary where he will talk about why we created this video. We'll also follow up with a detailed art making of video to highlight how the artists benefitted from putting this video together.

1. Any jump capable fighter is going to need a hundred tonnes of ballast, at least during transition.
2. Dispersed structure, or charitably, close structure, configurations seem a bad idea for combat orientated spaceships, especially if the enemy gets the option for aimed shots.
3. How useful is a pop up weapons mount?
4. Broadsiding requires a cooperative opponent, or a slower one.
5. I'm sort of toying with the idea of using a double hull for crew quarters in order to use a cheap non gravitated hull; as in all things, it's a cost benefit exercise.

1. Not sure which would be better, hard shell, or a softer thicker crust that would absorb most of the impact.
2. Operation Chariot indicates you use an old ship, rather like ye fireship of yore, and pack it with strategically placed explosives.

Question for the Braintrust:
Is there a write-up such as history, who made what and where is it retired to, stats, deck plans, etc for the Ship Tenders and Ship Riders for the OTU. I'm looking at the Gallant class Battle Rider and Triumph class Battle Tender for POD as a system defense force. I have read through the Battle Rider space battle game and the wiki. Thanks

Donno; the concept popped up in the first Fighting Ships.
My overall impression is that the writers are clueless about them as well, but carrying around subcraft was probably recognized as useful a long time ago by the Vilani; once the fat hit the fire, it probably was the simplest way to transport military spaceships to the front, preserving their small number of jump drives.

Starwarships: Star Wars: Inside the Imperial Star Destroyer
The iconic Imperial-class Star Destroyer first appears in the opening scene of Star Wars in 1977, where the Imperial Star Destroyer Devastator, with Darth Vader on board, chases the CR90 Corvette Tantive IV above Tatooine.
Manufactured by Kuat Drive Yards, the Imperial I-class Star Destroyer is described as a technological successor of the Venator-class Jedi cruisers used by the naval forces of the Galactic Republic during the Clone Wars.
Ever wanted to see how an Imperial-class Star Destroyer actually works? Here is a deeper dive inside an Imperial Star Destroyer. A technical 3D animation showcasing the power behind a Star Destroyer.
But also learn how this Star Wars capital ship works and why it's considered one of the most iconic spaceships in the Star Wars saga.
They were nonetheless essential in the Imperial doctrine of planetary containment and fast infantry deployment, and the vessel was noted as one of the most resource-intensive ships in the Imperial Navy.

1. Ideal configuration for forward firing spinal mount.
2. Point defence can be emplaced along the rear engine diamond, allowing front and rear line of sights for anti missile defence.
3. Second line of point defence weapon systems can be positioned on the nose.
4. If you start twisting to better position the weapon mounts, you're not really accelerating forward.
