the most reasonable answer would be costs: the Venera landers only survived a very brief time on the surface to send back a few pictures. The hazardous pressure down there is probably going to brake today's equipment as well. So the costs do not justify the means. Also, Mars is much more interesting from a long-term perspective. What are we going to do with Venus? Attempt to land Mark Whatey there?

But I agree that this one pic we have from Venus is making me quite emotional. In my view, having been to Venus and having actual surface footage tops anything on Mars today. But perhaps that's just my feelings for Venus.

to be fair, the soviet space program doesn't get enough credit for most of their (absolutely mindblowing) accomplishments. At least in the US. We put a man on the moon, but we wouldn't have if the USSR hadn't already beat us to the punch on so many other milestones.

Simply put: Venus is hell. Namely, the high pressure and temperature on the surface means a shorter life for landers and rovers. This means less science value per dollar. Also, looking broadly Mars is a much more accessible destination for potential manned missions since the surface is more forgiving.

Same applies to Mercury, the main issue is that at high temperature materials loose a lot of their strength. In order to get around this you'd have to use more heat-resistant materials (such as steel, ceramics, or concrete) but this also makes the vehicle heavier and more fragile, a problem given that it has to be launched into LEO then landed on Venus.

>not profitable
Nothing under government control is profitable. Just look at Amtrak vs. Conrail. Both nationalized in the '70s and started sucking down money. During the '87 crisis the government miraculously sold off Conrail to private sectors. Now? Conrail is successful and pulling a profit. Amtrak? Well that is still nationalized and as we know, is still sucking down money.


If space were truly privatized and not just run into the ground by government, we would be mining everything in sight for resources.

You honestly believe we wouldn't just start hauling in iron asteroids, refining and building shit? It'd be cheap as fuck once established, seeing as there is no longer a need to get resources off Earth.

The potential is boundless, but so is competition. And why have that when everyone can just be your slaves.

This is what's wrong with NASA's planetary science program. Instead of pursuing the best science cases money is funneled into Mars because to the dream that one day idea of sending astronauts. It's apparently important to look like you're working towards that despite the fact that many of these missions add nothing to a manned spaceflight attempt.
>>
>>8106081

>the best science

Science is expensive, and regardless of manned flights there's more data value in Mars since Martian landers/rovers/etc last longer. The value per dollar is greater so that is NASA's aim. Also if we're talking about pure science value, Venus is #3 to Titan and Europa.

Though, even then manned missions would remain the goal since they have the maximum science value. Being able to have a staffed laboratory on another planet is a big deal.
>>
>>8106094
>Science is expensive, and regardless of manned flights there's more data value in Mars since Martian landers/rovers/etc last longer.

No. Data does not equal science. There is demising return. If science was purely a function of data missions would never be switched off, but they are because eventually they aren't telling you anything that's worth the cost.

Secondly planetary science is not just about landers, it's mostly orbiters. Venus isn't particularly hostile to orbiters.

>if we're talking about pure science value

That depends on the scope of the opportunity and the proposals. You cannot plan an outer solar system mission and a midex budget.

>Though, even then manned missions would remain the goal since they have the maximum science value.

But at what cost? It's fine to claim that astronauts can do more but if it costs 100 times more and produces quite little where does that leave you?

It always makes me angry when people refer to the space race and its winner and put all their nationalism into their one-sided argument. I don't think anyone won the space race. Both achieved miracles but were also dependent on things learned from explorations in the past, both US and Soviet.

We should be thankful to both, for the cold war led the development of many of the current technologies we value today. In many respects, I wish there would be a new cold war (regardless between what nations) because this type of competition is what truly drives technological progress. JFK didn't initiate the Apollo program because its cool, he did it out of pure pressure by the Soviets, who were by far outperforming at that time. Politicians and the public is lazy without the right incentives.

As for the space race: it boils down to whether one prefers quantity before quality or vice versa. Many of the big miracles of being "first" were achieved by the Soviets, they made countless achievements for humanity while the US was jerking off to spy satellites. In the end of course they masterfully won the "moon race" which should be considered a sub-category of the space-race, but not the finish line of the whole space quest. It is highly debatable to say whether this major achievement outperforms so many others on the Soviet side. I prefer to think of both having contributed their fair share to humanity.

Of course since then, NASA has leaped forwards and that is good. I wish NASA and SpaceX all the best. I am a true fan of them.

pressure is no problem, heck even the sulfuric acid clouds aren't much of a problem. Venus surface pressure is 92.10 bar, we have been making pressure vessels that can contain this for years, a standard scuba tank contains 207 bar. At the surface the concentration of sulfuric acid is basically nil.

The real issue is temperature, it is so hot that conventional silicon based electronics break. For this we need special electronics that use silicon carbide as a semiconductor and cooling if we want something that's not dumber than eniac. Silicon carbide should work just fine at Venusian temperatures, but it is challenging to make silicon carbide ICs. Even then you are pretty limited, you gotta use big transistors(microns!) so you don't get low operating frequencies and can't use much. Not to mention that the TRL of silicon carbide electronics is still pretty low.

So if you want something that can actually computer, you need to cool it. Cooling requires power and the only way we could get enough power to practically power it is with plutonium, which NASA doesn't have much of. Oh and to get enough cooling you need a special stirling cooling system based off of NASA's advanced stirling radisotope generator(ASRG), which is not expected to be flight ready until 2028 due to funding issues. Pic related, a plutonium powered rover, which we probably won't be able to build until >2028.

This brings us to the next issue of power. Because Venus is covered in clouds, solar cells are shit on the surface, because venus is hot RTGs generate a lot less power, because NASA doesn't have that much money we can't use better tech to generate more power from radioisotopes.

well it was a race for being "first", ideologically driven by both US and USSR.

What I will agree on however, is that after the USSR fell apart, western media repeatedly shaped and continues to shape biased information about that time. There should definitely be more appreciation for the Soviet programs. I guess its part of western propaganda, much like Soviet propaganda would have downplayed any US achievements.

In my mind this type of winner-takes-it-all mentality and the overall bias is pretty disgusting, but as we all know - the winner writes history. I bet most americans have never in their life seen a decent documentary about Yuri Gagarin's flight to space despite it being such a significant event in history - yet, they have seen far more than enough about the moon landing. It is just the way things are, unfortunately.

Nah man, the USSR did a bunch of dick-waving too. Take Luna 1-2, the whole purpose of the mission was pretty much just to hit the Moon.

The correct answer is "because most people realized there's not really a point". You are not going to Venus, in any more likely fashion you are going to Jupiter. It's fucking retarded to spend resources investigating more of something of which you're already well aware and have no propensity of colonizing or otherwise exploiting.

It's still sending back data.

the fuck is pressure supposed to cause microfractures in electronics? Solid fucking silicon does not spontaneously fracture under uniform compressive loading.

Here's a fun fact for you, the Trieste, a submarine which visited challenger deep, used regular quartz arc lamps for illumination. They were capable of withstanding the pressure without any modifications. A glass tube withstood pressure at the bottom of the ocean.

That will only prolong the inevitable. For the venus rover above, electronics have to be put in a thermos


As it turns out, wind power is actually an option on venus. You can't generate enough to keep stuff cool with out a really big turbine, but you can generate decent enough amounts for science. It is not that windy on venus, but because the atmosphere is so dense you can get reasonable amounts of power.

NASA is currently investigating pic related. You build a landsail. It uses some big high temperature gallium nitride solar cells for power and a big sail to move.

The design calls for all silicon carbide electronics. The thing is basically a glorified RC car and relies on a satellite for control.

Yes, and the capsule actually produces lift, so by offsetting the center-of-mass and rolling the capsule, you can steer it through the atmosphere.

>>8106670
yes of course there is diminishing profit, but perhaps the initial markup prices are huge that you can charge before the price drops to the market equilibrium, which would be equal to the marginal costs of obtaining another rock.

it's solely based on supply and demand. it's the price of exclusivity, not a rip-off. Everyone knows it will decrease in value if supply increases.

At the surface, yes. But the majority of an Earth reentry occurs in the thin upper atmosphere, not at the surface. Mars' atmosphere is plenty thick enough to be useful.

Landing on the moon isn't so hard because you have "all day" to putz around with your trajectory and position yourself in a relative fashion to the moon surface.

For Mars, it's not so simple. If your trajectory is so broad, you'll skip right off, like a spun flat stone over a pond. The appropriate trajectory for re-entry is direct, and then, unlike earth, the force of your vehicle's thrust is pushing upon far less atmosphere, requiring a multiplicative amount of thrust to slow down a given amount of mass, or you'll just plummet.

>>
>>8106733
really depends on how fast supply increases. Everyone has a different willingness to pay. If your moon rock will lose half its value in about 10 years, then there would likely still be people buying it now because its worth it for them. Also, many would do it out of fascination, to have something from "up there", not everyone will treat it as an investment. I continue to think there will be a huge market for moon rocks.
>>
>>8106744
It's not easier to go to Venus, you'd need a craft that didn't compress under pressure close to that of the Marianas trench (see discussion above), and that requires more fuel that it's worth to just get there and sit. Then you're never getting off the stupid planet with any amount of fuel that you were capable of bringing, unless you have some new quantum drive.
>>
>>8106716

The dragon capsule is designed to land on any body(also anybody) in the solar system apparently. But one has to carry more propellant for landing in a vacuum.

Landing on Mars also generates more hype.
>>8106720
And how does no atmospheric drag make it easier to land? No drag means no parachutes.

The delta V cost to land can be lower. The MERs were set on a mars intercept course and braked using just the atmosphere and bouncing around. Although a small amount of delta V was used to make sure the parachute and what not landed away from the rover

Also, I guess I neglected to mention, parachutes are going to do approximately jack dick for a manned vehicle to land on Mars. You couldn't possibly account for the mass of a large enough parachute, as cargo, to make enough difference for a multiple ton craft in such a lean atmosphere. The "bigger" the chute, the "heavier" the payload and you're making a worse problem. Eventually you'd need a parachute miles across.

Push the minimum wage to $20 per hour and there will be no reason to hire anyone over anyone else for anything but their skill. Take the money out of the manager's pocket and your managers will find a way to boost productivity by hiring qualified hard working people, or they won't get any money themselves.
The problem with capitalism is it doesn't work. It sacrifices the physical benefit of collective action for winning the zero-sum game of dividing up the profit. Seeking profit means managers make profit decisions, not productivity decisions.
A high minimum wage discourages the theft and the organizing to exploit, and encourages the hiring of long standing employees, not transient illegals.

now getting back to Venus. One way to make a rover that can survive Venus is to not use any electronics, that is you have a rover full of clockwork and mechanical parts. NASA Insitute for Advanced Concepts has a study on exactly this investigating whether mechanical automata are viable for missions to extreme environments. pic related is the proposed Automaton Rover for Extreme Environments. The cool thing about being completely mechanical is that stuff can operate at very high temperatures and pressures. As long as it doesn't melt or soften it will still work.

https://www.nasa.gov/feature/automaton-rover-for-extreme-environments-aree

>>8107595
Which brings us to Neptune. One of the proposed applications of automata is exploring the hot, high temperature interiors of gas giants like Neptune. With refractory metals and ceramics we might be able to make stuff that can reach neptune's surface and survive. If we make the probe out of solid diamond, we can send stuff very deep into neptune.

In a sense, people are worth what you pay them.
In fact, since the supply of labor always exceeds demand, market forces will always undervalue labor.
That's why we have a minimum wage in the first place.

All your competitors will also be paying $xx.

>market forces will always undervalue labor.
This is just incorrect. Because of the minimum wage labor is overvalued and jobs aren't created, which leads to oversupply of labor, and wages being pushed down to minimum wage. Take for example picking up trash on the side of the road. It's a job that's worth doing, but it's not worth 41k a year, and 41k a year is what we would have to pay someone to pick up trash under your 20$ minimum wage. So because of that high wage that job wouldn't exist, and because of the high minimum wage now, that job doesn't exist in many places. But of course, according to you it's worth it if we pay them, so if we made the job it would be worth it. When really, it's the other way around. If it's worth it the job is made. And it's not worth it. So the job isn't made. The person isn't employed. And there's more people competing for other minimum wage jobs, which leads to the over saturated labor market, and prevents the market value of a wage from rising. If we let people work for less, many minimum wage jobs that already exist would be worth more.
>But, if I have to pay someone $xx an hour, I won't be able to complete!
It's not about competition, it's about income. "If I have to pay someone $xx an hour, I will have to charge $x for my product at the current sales rate in order to stay in business. Will people pay $x for my product and still buy just as much of it? Probably not, so I had better get out of business before I start losing money.

My parents were born too nigger. That doesn't mean people will magically start producing more once wages go up.

Care to point out where the flaw in logic is exactly? It's basic supply and demand. Labor supply is high and demand for it is low. Create more demand for it, and labor will be worth more. There's an over saturated labor market, there's high amounts of competition for minimum wage jobs that unskilled workers need. If unskilled workers have other options that competition lessons, and the people currently hiring minimum wage people have to raise wages to attract more employees.

Calling people retarded niggers doesn't really educate them or prove your points well.

You're right about saturation but lowering the minimum wage will only further reduce the standard of living.

>>
>>8108284
I don't really see how it would lower the standard of living. More available jobs means greater opportunity for people who are currently unemployed.

Raising the minimum wage hurts the people who have living standards even lower than the people working for minimum wage.

>>8108187
>create more demand and labor will be worth more
This is the literal retardation in your mind. You're literally paying the people less. It is not worth more if you are paying them less. Jesus. The unemployed literally do not have jobs. Even if you assume the magic that owners are not sociopathic greedy fucks, the people that enter the workforce will inherently be working for less than the job is presently valued, and any people previously working at minimum wage will have their pay lowered. If the labor pool was fully occupied, filling a new job would require that new job being payed more. When the wages are the same, you can't fill that job (as there would be no need for any employee to switch) and worse, if you create a job that is payed LESS, the only reason an employee would take that job is if they were forced from a higher-paying position. You are too dumb to grasp all the logic involved; I can't tell if you are pretending to be retarded or if you actually are.

>>
>>8108313
>You're literally paying the people less.
Paying the unemployed people less than zero?
>less than the job is presently valued
The jobs I'm talking right now are currently valued less than minimum wage, so they can't exist because of the minimum wage. Take for example a job valued at $5 an hour. You can't hire someone for $5 an hour, so that job just doesn't exist. The work the job requires doesn't get done, and people who are willing to do it for $5 can't, because the government wont let the job exist.
>any people previously working at minimum wage will have their pay lowered
Actually the opposite will happen. With more jobs opening up, there's a higher demand for labor, less competition for the minimum wage jobs, and the value of their labor goes up.
>If the labor pool was fully occupied...
In this example you stated the exact point of eliminating the minimum wage. Wages for jobs have to go up or the jobs wont get employees unless people were forced to do the job. People aren't forced to do the job, so either wages go up, or the job doesn't get done. That's how supply and demand for labor works. If the demand for a job isn't great enough for a higher wage, the job wont get done until that supply of labor is there, or the demand is great enough to raise the wage.
>A million people working minimum wage can afford $400 rent.
In this example, a million people aren't working at all, who obviously can't afford rent on their own.

That would only make sense if EVERY SINGLE POSSIBLE EMPLOYEE was hired. As long as there is one more person than those employed, the person is replaceable, and will have to suffer low wages or be replaced. This applies to a group level, 10 people working for $5.01 know that each of them could be replaced by one person will to work for $5.00, so they have to accept wages suppressed to their value. As people are willing to take risks, you will inherently have a race to the bottom because someone will burn any available resource to survive (including those of their neighbors, look at niggers).

>fully employed labor market
Literally impossibly and completely psychotic to consider. Even if there was no minimum wage, there are not enough jobs for people. Find me a place without minimum wage that doesn't have at least 10% of it's population living in abject poverty or constant warfare.

>rent
In your example, two million people can't afford rent. In mine, one million can't. Get the picture?

Here's a thing with minimum wage: if it was bad to raise, you could show plenty of situations where raising it was detrimental. If it was beneficial to lower, you could show plenty of situations where everything improved as a result of lowered wages. This has literally never been the case, as wages have always been suppressed. There are clearly conditions where raising the minimum wage is bad, and we have yet to reach them. Even with threats of robots replacing fast food workers, we all know corporations are slow as shit to do anything, and worse, terrible at doing anything right.

I'm wondering if you could could have some kind of self inflating airship to take on Venus. The probe would deflate it's balloon to sink down to the surface, where it would perform observations for a hour or two. It then re-inflates the balloon, ascending back up to high altitude, where it can cool of, recharge it's batteries and prepare for the next decent.

This has the added bonus of letting you cover a wide range of locations.

That's Seebeck generator to you mister. The Peltier effect is the creation of a temperature difference by an applied voltage, the Seebeck effect is the creation of a voltage by a temeprature difference.

Seebeck generators do not work without a temperature difference. One could use the temperature difference between the inside and the outside of the craft, but that would just make a really shitty battery that stores energy in the craft's specific heat.

If you mean radioisotopic thermoelectric generator those suck at venusian temperatures.

I think the dept/composition on the dust is different from where you are on the moon actually, the Apollo lander didn't sink too far in( by the looks of the legs), yet a few times they managed to crumple the rocket engine bell underneath the module when landing on hard surfaces.

The extent to which SpaceX is thinking ahead is insane. All of those boosters they've been landing? Yeah, those were carried out in a way so that the most critical portions of the operation occur in the section of Earth's upper atmosphere that most closely resembles Mars' atmosphere. They've been testing Martian landing the entire time they've been experimenting with propulsive landing.

By the time Red Dragon reaches Mars, SpaceX will already have the data from several dozen similar landings under their belt.

Colonizing *any* body in our solar system outside of Earth is going to require imports, at least initially, so that's no real excuse. Eventual autonomy is possible given enough manpower and industrial momentum.

Mars is easily the most feasible target for long-term colonization, at least for next 2-3 decades. It's by far the most earthlike body within our reach, isn't all that far away, and poses less challenges than other bodies (the moon's veil of electrically charged, unoxidized and ultracorrosive dust for instance is a huge problem that Mars doesn't have).
>>
It won't take long before you see the end of most manned missions. A lot of the difficulty of space travel is to haul humans and cargo associated with keeping them alive.
>>
>>8110889
I disagree heartily. There's not but so much an RC robot built with rad-hardened Gamecube technology can do. A human, while expensive to send out, can do anything imaginable.

It will take several decades before rad-hardened robots with capabilities approaching even a tenth of a single human of capable of is available, so unless we're content with moving at the pace of a frozen snail, money would be far better spent on making human spaceflight cheap and safe. The cool thing about that is that robotic spaceflight will also become exponentially cheaper, making launches of probes, landers, and rovers as commonplace as football games.

I don't know about that. Even normal earth robots are just now just BARELY starting to not suck at being bipedal, and even then there are still huge battery issues to deal with not mention all of the situations AI software cannot handle yet (still more than it *can* handle). Pile that on top of issues of keeping mechanical joints cool in a vacuum and the fact that radhardened electronics lag ~15-20 years behind consumer tech and you've got a laundry list of impediments to deal with before you've got something usable. As a whole, it's just as hard if not worse than keeping humans alive in space - the difficulty is just distributed differently.

No it isn't. The longer you keep a human crew in space the more of the precious weight capacity has to be dedicated to things to keep them alive, which is very prohibitive for something like exploration. It's why the only feasible way to get people to Mars is to make the trip one way, at least for now.

Robots being limited by "technology" is a far better problem to deal with than the insurmountable problem of months or years worth of food or water for a human crew.

I guarantee the missions to Mars over the next few decades will all be unmanned. And that these will continue for decades until a large settlement mission is undertaken. The reasoning they will give, and it is the correct one, is that removing the human crew dramatically simplifies the design specifications and risk associated with the missions so they can focus on tasks that aren't retreads of the moon missions mainly landing and deployment of payloads to the surface.
>>
>>8111007
If Musk has his way, the first human will step on the surface of Mars some time in the mid 2020s. His timelines are always incredibly optimistic (to say the least), but even with delays I don't see that happening any later than 2030-2035. Certainly not "decades".

Mission risk is 80% tied up in taking off and landing. If that can be smoothed out (as nuspace companies are achieving quite rapidly now), all that remains for risk reduction is getting from point A to point B and surviving after landing, The rest really boils down to the reliability of onboard systems and sending a rocket adequately large for needed supplies, or even sending said supplies to Mars years ahead of time so they'll be there waiting once people arrive.

Personally I think this will be delayed by the simple fact that theres no money in a mars mission, whereas asteroid mining and lunar mining will be hugely profitable

Here's to hoping that spaceflight becomes affordable enough for non-governmental organizations to feasibly fund.

>>8111136
>Venus is more so
In size and gravity, yes. By every other measure, it's about as earthlike as Jupiter or Saturn. And airships are a horrible idea because we'd have no way to get back - at least on Mars we're on solid ground so producing fuel and launching a propulsively landed rocket is feasible. You can't launch a rocket from an airship.

>Which entirely depends on the availibility of necessary resources, if water is not readily availible, then mars colonization will have to wait.
There's plenty of water on Mars. We can either land around the polar regions and mine ice (probably easiest) or process the regolith which in some areas is something like ~40% water by volume (harder but opens up landing site options).

To continue on this, Mars as a whole has enough water that if just the caps alone were melted, the entire surface could be covered with 2" of water. That doesn't even count what's locked up in the soil or underground glaciers and aquifers. Water on Mars really isn't that much of an issue.

Yes it would require a different mission architecture, and probably a 2 stage rocket to get back to earth, but its nothing technically impossible.
>>
>>8111265
It's considerably more involved than landing a rocket on Mars, flipping on a fuel collector, and taking back off, though, and that's my point. It takes zero additional infrastructure - all you need is the rocket that brought you there and your fuel collector. That's the sort of efficiency we're going to need in our first attempts at colonizing other planets. Venusian airships can come when it's not such a big deal to undertake manned missions.
