>The United Arab Emirates has released new details about its planned mission to the main asteroid belt, one that is similar to an ongoing NASA mission.
>its Emirates Mission to the Asteroid Belt (EMA) is scheduled to launch in March 2028, flying by six asteroids in the main asteroid belt before arriving at a seventh asteroid in 2034.
>The MBR Explorer spacecraft bears a resemblance to NASA’s Lucy spacecraft
>It will fly by Venus in July 2028 and Earth in May 2029 before going by the main belt asteroids Westerwald, Chimaera and Rockox between February 2030 and January 2031. A Mars gravity assist in September 2031 would set up three more asteroid flybys, of 2000 VA28, 1998 RC76 and 1999 SG6, between July 2032 and August 2033.

> For the city of Chicago, the total cost for a conventional PV array system plus the required energy storage to deliver 2GW of baseload power in December becomes about $480B, with dedicated land area of 800,000,000 square-meters (a circle about 32 miles across). For a similar 2 GW of baseload power, SSP delivering an average 90 Watts/square-meter of receiver would require only 28,000,000 square-meters (a circle of only 3.6 miles), plus the space system, which is discussed elsewhere. Moreover, the power from a single SPS could be delivered in the northern hemisphere in December, but in the southern hemisphere in June; and shifted from East coast to west coast as demand shifts during each day. All-in-all, this is why SSP might well make a fabulous partner for conventional solar power—rather than a competitor.

a very good point I haven't thought about before, you could have one sender satellite, but multiple receiver antennas in different locations and send the power to where it is most needed at any single point
basically dispatchable power that can be shifted from one side of the earth to another
you need the receiver rectenna array though, which might not be that cheap

This Casey guy seems like an actual stupid person, really confident in his stupidity.
Here
https://caseyhandmer.wordpress.com/2022/07/03/powering-the-lunar-base-version-2/
He argues that the best way to power a south pole lunar base is by generating power on the ground on earth and beaming it to the moon with microwave arrays. He defends this by pointing out that power is cheap on earth.
>solar panels on the peaks of eternal light
Not possible because it's "fixed infrastructure on the moon" and therefore impossibly expensive
>nuclear reactors
Too heavy he says.
He operates in the mindframe of everything being launched from earth, no industry in space is possible. This extends to his Mars terraforming program here
https://caseyhandmer.wordpress.com/2022/07/12/how-to-terraform-mars-for-10b-in-10-years/

I don't like it because he's all fart and no shit. All he can do is throw out a few loose cost estimates that are so far off the mark it's worthless. He says that a mars colony will be importing food from earth for the first decade because it's cheaper than growing food on Mars.

If you're on Mars, living there, depending on Earth is INHERENTLY expensive. There's no scenario where importing food from Earth is cheaper than growing it there.
Casey has this fixed idea that any sort of construction on another planet is "fixed infrastructure" and therefore impossible to justify from a financial perspective. He shuts down at that point.
Yet he's all for terraforming Mars. He thinks it's an important first step before colonization makes financial sense, and he wants to do it by turning phone manufacturing plants into making tiny origami reflectors that unfold into large mirrors, launching them from Earth in Starship, and parking in Mars L2 shining a tiny bit of light onto the poles. He is convinced that Mars is just waiting for a slight push to flip into a comfy state with rainfall and a nice thick atmosphere (albeit CO2)

That makes zero sense. Mars cooled as the sun gradually became brighter and brighter because its original atmosphere has been stripped away. Its oceans (if it ever had any) were stripped away. It's not all hidden at the poles or underground, it's just gone.
Terraforming mars means importing gigashitones of volatiles from the outer solar system, and once you start doing that anything else you'll do to heat up mars will be comparatively pointless.
At least he's not stupid enough to suggest colonization before terraformation.

The effects of SO2 are pretty well understood, considering that it's been released by industry for quite some time (largely from coal), and by volcanoes by *quite* some time. Not to mention it doesn't stay the atmosphere for that long, couple years. Excessive cooling is by far the least likely unintended consequence. If it does happen it's entirely deliberate.

No supporting any of his other points, but
>A Mars colony will be importing good from Earth for the first decade
is almost certainly true. Depending on the definition of "colony," of course, but think about how long everything takes in spaceflight. We can't just bring a bunch of seeds and plant them in the dirt. Hydroponics etc are infrastructure-intensive, which means mass-intensive. And they'll be competing for mass with every other facility the colony needs. The first decade will be about energy, return-flight propellant, oxygen, and water.

I mean, just a point of comparison: what percentage of their food do they grow on the ISS? And before you attack the comparison: yes, it's different, but not that different. Not in the first decade, at least.

Depends on the tech-level. If it's with current or near-future tech, then I'd imagine interplanetary warfare unfolding like a game of chess. All the pieces can defeat the other in one swift move, but a piece can be protected because an ally can take revenge on anything that kills it.

[Anonymous No.15482273]

>>15482250
I haven't put much thought into interplanetary warfare with fusion drives, but my best guess right now is that on the interplanetary scale it would still be like lower-tech warfare, but fighting within a planet's sphere of influence would involve more careful maneuvering due to the ships having a larger "kill area" around them thanks to their higher energy output.

Another thing to consider is information warfare. Sure, you can't hide in space, but the location of the combatants must be observed, processed, and sent to command. I imagine that the primary information fighting would be lasers vs telescopes. Telescopes are highly sensitive and taking down just a few with high-power lasers can easily mess with the enemy's ability to respond to your movements. How it would fold out depends on tech-level. With modern tech, the fight favors telescopes or at least is balanced due to the limitation of power outputs that a ship can manage. With fusion tech, the fight favors lasers as any ship can dump a couple of gigawatt photon blasts with ease.

Materials for building stuff in LEO - Delta v from moon to LEO costs like 20 time cheaper than from Earth so steel and aluminum mined and smelted on the moon will be much cheaper in LEO than the same made on Earth. Also, Titanium is a cool building material but really expensive because it needs to be separated from oxygen - is smelted and refined in vacuum - expensive on Earth but not on the moon. Cheaper to begin with and cheaper to move than from Earth. So industry in LEO really benifits from industry on the moon.

But we don't have any martian soil
We have (((regolith simulant))) which is literally pulled out of the asses of the researchers.

[Anonymous No.15482886]

ok, reading the paper
the first portion is measuring how density and gravity affect the angle of failure (AOF) of different soils, in some very cohesive soil simulants the AOF is basically infinite (particles glued together by friction basically)
there was a test of soil erosion speed dependent on gravity as well on different soil simulants
read again, erosion speed, not ultimate crater depth

in the second portion of the paper they looked at solid rocket plume effects on crater formation in a martian soil simulant, uncompacted and compacted
compaction done by layering 3cm, using a handheld vibratory device, 3cm again and so on
loose soil was made by "fluffing" and stirring the simulant (their words)

> Theuncompacted crater develops approximately 3 times faster than the compacted crater. The asymptotic depth of the crater is almost unaffected by the density of the simulant and is roughly equivalent to the plume extinction length. This result indicates that the plume extinction length (vs soil mechanics) dictates the size of the crater.

so again, the soil parameters do not affect the ultimate crater depth, its the plume
it just takes a second or so longer to dig a whole in denser, more compacted soil than fluffy soil

>>15482863
you are confusing erosion rate with ultimate crater depth
completely different things
analogous to how fast you dig vs how far you can dig, but if the former is measured in seconds and much shorter than the landing sequence, its basically irrelevant
soil properties do affect if the soil itself can support the lander even with a deep hole underneath but that is again something completely different

Look everyone! A gay retard!

The atmospheric pressure on Mars is 0.6% of Earth's and it's 0.18% oxygen versus 21% on Earth, so the oxygen partial pressure is more than 10,000 times lower, not to mention that there's much less water vapor and it's much colder.

>Grusch said the recoveries of partial fragments through and up to intact vehicles have been made for decades through the present day by the government, its allies, and defense contractors. Analysis has determined that the objects retrieved are “of exotic origin (non-human intelligence, whether extraterrestrial or unknown origin) based on the vehicle morphologies and material science testing and the possession of unique atomic arrangements and radiological signatures,” he said.

MUCH cheaper to make a short engine bell, considering the fancy metallurgy that goes into high-temp alloys. on the scale of a falcon 9 launch it might only save a few percent costwise, but spacex is all about eliminating unnecessary expenditure. If the mission doesn't require absolutely 100% of the upper stage's delta-v then it makes more sense to use less engine bell, instead of using less fuel.
