You could argue the Moon Landings were unneeded and were better done with robots, and actually the scientific goals were done by robots by both NASA and the Soviets long before Armstrong set his foot on it, but Apollo is what we remember today.

>life support
Again he explained that.
The only technology we would need to improve, notice IMPROVE, not invent, is water recycling.
As we speak there is an ISS experiment exactly doing that.

And no matter how sohpisticated your robot is, it will not reach the ability and on-the-spot skills like repairs, adapting to unforseen situations, changing mission parameters etc in the near future.
There is a reason robots haven't taken over manual labour on earth yet, it still requires a lot of progress, not to mention the kind of trivial code bugs that still plague missions today.

You are doing exactly what he is critizing, you demand a technology to be progressed in order to achieve something that could be done with technology we have today, furthere pushing the date of any meaningful mission, manned or unmanned, into the future so bureaucats can continuie to claim "oh well why spend billions on the future of humanity in 100 years when we could spend billions now on more important things like buying 2-3 new stealth bombers".

How do you make a sustainable colony on Mars when it's highly likely that the low-gravity of Mars would be detrimental to embryonic development?

>Build centrifuges or other gravity simulators.
Even if that worked the growth of the colony would be directly tied to how many of these machines could be kept operational at any given time. What if they all broke, and what if they couldn't be repaired with supplies from Mars alone? And how would they even work, are you just going keep women strapped into them for the duration of their pregnancies?

>> No.7710284

You don't need deadly radiation, the light atmosphere should be enough to stop humans from walking around outside.
And even if you created an Earth-like atmosphere what are humans supposed to do without machines? Build a sand castle on Mars?

>>7710142
The problem with life support isn't inventing it, it's the whole complex mechanism of supplying nutrition and shit for the entire duration of the trip. Humans are notoriously inefficient to operate and die easily.
The moon landings were 50 years ago. Robots have advanced a lot since then, humans haven't.

Yeah it is impossible to send dry astronaut food for 2 years with current technology, you could not possibly fit a lot of dried food on the unmanned ERV that lands a year before the manned mission, right.

Sarcasm off because that is just sad.
The sample returns were only a main during Apollo 11 and 12, further samples were just bonus.

It's not impossible, it's just unnecessarily expensive.

Instead of using resources to get humans back from Mars we could be getting robots to Jupiter and beyond.

One step at a time.
First you do exploration missions, Apollo style.
You gain a ton of knowledge about the enviroment and requirements there for all kinds of spacefaring applications.
Then when those new challenges are solved you do permanent settlements, which will be muuuuuuch later.
But even those station are ISS style, you rotate professional crew in and out, why would you want them to be born there?
Do we send babies to the ISS to do research we want now?

An exploration mission is possible today.
A permanent colony where people actually are born and raised is SciFi for now and not required for short and medium term scientific gain.

This is a solved issue.
Do you go to a climate change conference and ask how they would even measure temperatures because nobody thought about thermometers?

>A person in a bulky spacesuit ends up a different matter.
Still more agile and flexible in what range of operations are possible.

>You could say the entire landings after 11 were mostly bonus.
The early ones were not because they had additional experiment packages with them.
There were more missions after 18 scheduled which were cancelled exactly because there would be no more gain.

>Instead of using resources to get humans back from Mars we could be getting robots to Jupiter and beyond.

Zubrin's notorious for half-assed work. In his book, "The Case For Mars", he assumes that it would be no problem to rearrange space shuttle parts to make a Saturn-V-like expendable superheavy-lift rocket. This was a major influence in the miserable Constellation and SLS programs: jackasses like Zubrin talking straight to Congress, trying to get them to meddle in technical decisions.

Another point he fell flat on was assuming that it would be no problem to throw a huge tank of liquid hydrogen to Mars, prevent it from boiling off during transit, and land it on the surface.

He's ridiculously optimistic in his assumptions. It's like he thinks development doesn't cost anything and everything works the first time.

It's not "hard for me to grasp", it's bullshit.

The technology required "exists today", in the same sense that in 1996, America just had to play lego rockets with shuttle parts to have something better than Saturn V. Two decades and billions of dollars later, the technology that Zubrin said "exists today" is now predicted to arrive sometime around 2030.

Zubrin routinely confuses knowing how to make something, in principle, with having a mature product on hand.

My point isn't to say that Mars missions are unfeasible, it's that it's better not to use humans. Not because it's impossible to send humans but because the effort is better used elsewhere.
Sending humans to Mars is trying to spin the wheel of history backward by half a century. Where do they want to go after Mars? Zubrin dreams of Mars as a springboard for future missions but you've practically exhausted your options at that point. Putting humans on Mercury or Venus isn't even realistic to do from Mars. He's downright obsessed with discrediting other missions like the asteroid redirect stuff.

The only answer is that Zubrin doesn't like it because it removes resources from his dream.
There's nothing wrong with establishing bases on the moon. Both for stationary exploration via telescopes and for launching future missions, not necessarily to Mars but to space and beyond.
Ceres would probably be the best alternative for a mid term base or maybe Vesta. Phobos and Deimos and the other asteroids are too small.
What was so bad about Phobos being circular and equatorial again? Even if you can't reach the entire surface the equatorial region is the most interesting anyway since it's easier to launch from there than from polar regions.

Which makes any non-Lagrangian refuel station unfeasable.

>Which makes any non-Lagrangian refuel station unfeasible.
Is there any particular reason to restrict yourself to stable or quasi-stable positions? You could be on any orbit.

So your argument in favor of Mars Direct is, "Sure, it's just a crazy-expensive stunt like Apollo, but THIS time it'll be different afterward!"

Mars Direct is a rush to put a man on Mars before Zubrin dies, so he can see it and die still imagining that it mattered.

If we want to go beyond the Apollo model, we have to focus on cost-effectiveness from the beginning, not throw money at things to get fast results with bullshit arguments that this is useful experience.

We need to follow the Wright Brothers model, not the Langley Aerodrome model. We have to start with affordable rocketry and life support first, and evolve it to be more capable, not start with capability at all costs and evolve it to be more affordable.

You want to send people off on a three-year deep space mission when we can't keep a guinea pig alive in LEO for three years without resupply? ...when we can't keep people alive for three years in a hermetically-sealed chamber on Earth? You want people to spend two years on Mars when nobody has spent a week on the moon? You want to build an independent base on Mars for a few billion dollars when our resupply-dependent base in LEO cost half a trillion dollars?

Practice yourself, for heaven's sake, in small things, and thence proceed to greater.

Apollo was not a success story. It established the character of NASA's manned program as impractical, symbolic, uneconomical, and silly. NASA needs to abandon all aspiration to silly stunts and symbolic gestures.

That is no particular challenge. The thrust-to-mass ratio needed is small, the vacuum environment is ideal for rockets, and the delta-V cost is modest. It's also possible, thanks to the low gravity and lack of atmosphere, to build catapults. You only need to accelerate to what would be about mach 8 in Earth's atmosphere, so there are various ways to achieve that with a kind of train or gun.

The point of a moon base is not to assemble missions there. You don't send stuff from Earth to the moon, then from the moon to wherever you want to go. That would be stupid.

A moon base would be:
a) a proving ground for the technology to live beyond LEO, and
b) a source of raw materials, particularly propellant and mass for shielding.

If we can't survive and usefully extract raw materials on the moon, we're certainly not ready to go to Mars. Building a catapult on the moon to throw lunar material to orbit would hugely expand our capabilities in space.

In some ways, the moon is a harsher place to survive than Mars, but there are no special launch windows and the travel time is short. This makes emergency resupply and emergency return both possible.

The moon is the right place to aim next.

The extra hardware needed for humans can’t be justified by “inspiration” and so forth. We need scientific gains, not notoriety 500 years from now.

Apollo lost support within one landing. Many Americans still think NASA has been dead since 2011. They might not even notice if it actually died.

Robotics is an amazing field, and the people who develop and operate our probes are explorers in their own right. We need to play them up instead of glorifying an absurdly unsustainable, unfocused manned program.

It truly doesn’t matter if we know how to send people to Mars. The realpolitik is that SLS has a negligible flight rate, most of the elements needed for a Mars mission aren’t even contracted yet, and NASA’s budget doesn’t appear to be skyrocketing anytime soon. Space flight needs margins for failure and experimentation, and the current direction doesn’t even provide margins for complete, unbroken success. Our current direction is a practical fantasy, and Zubrin's concepts are a fantasy within it. We have a bird in hand, and that’s our robotic expertise.

Not that human spaceflight should die. Commercial has the power, with extremely critical government subsidy, to expand our frontiers sustainably without stunts we mourn 45 years later or congressionally designed deathtraps. Even more, commercially led human spaceflight will make space far, far more accessible than a government-dominated program ever will.

At most, the government should maintain US astronauts on commercial partners' stations and bases.

Only if there are profits to be made.
What profit is there to be made by gathering knowledge about the origins of terrestial and biological evolution in general on Mars?
No doubt once there is a reason to do so, like mining, the private sector will rush for the resources, but the first exploration has to be government initiated.

Well, yes, a government-led robotic program makes great sense. My argument is against a government-led manned program. We doubtlessly need reconnaissance missions to see what these places have to offer, but we can get those answers much more quickly, cheaply and safely with unmanned. If there really are any worthy resources those probes find, then commercial will chase them. If not, then we didn't waste 20 years, billions of dollars and, potentially, human lives just to pluck some dead rocks off of bigger dead rocks.

Civilization expands to profit, and expecting any other motivation as Zubrin and others do is simply unrealistic.

There are some big problems with the commercial mining aspirations, though. The infrastructure required to mine will probably far outweigh the returns until we get much better propulsion tech developed. The overhead will be manageable one day, but we're probably looking at another century.

Ridiculous as it sounds, I suspect the real ticket is tourism. It's a very pedestrian reason for something as traditionally serious and scientific as space flight, but the experience and perspective of space are literally the only thing space offers that we can't get anywhere else and for less.

Another possibility is that robotic missions discover life somewhere else and reveal some sort of genetic engineering or medical applications from it. That might be another of those "only in space" things.

Precious metals, though? Maybe not worth it this century.

Of course, space flight timetables are notoriously unreliable. The current state of the industry is almost like a new beginning. It's much tougher now to say just how quickly we'll see some truly mind-blowing developments.

That depends on the materials. Some carefully repositioned asteroids could act as natural fueling stations due to their water content.

Space-based precious metals, however, will probably remain uneconomical even for space-based applications. I can't imagine constructing anything in space out of anything other than preassembled modular elements sent from Earth. For now, the amount of labor, facilities and time needed are just too prohibitive to build anything in space starting from nothing but raw materials.

The real key to space-based manufacturing is asking what end it serves. If it’s just one-time manned exploration, then it’s probably not worth it. If it’s creating refueling stations for regular trips between colonies, then it starts to make sense. However, the size of colonies will probably remain very limited for a long time. There’d likely be lots of visitors, but very few permanent residents. A few select outposts here and there, essentially. That alone limits the amount of space-based infrastructure companies will need.

LEO orbits decay into the Earth atmosphere due to residue air particles slowing any object down.

This is such complete bullshit. In LEO, you are never more than an hour from being back on Earth. On the moon, you're never more than a couple of days from being back on Earth. On Mars, you are always months to years from being back on Earth.

Furthermore, if you're staying on the moon or Mars, you can get a resupply almost as quickly as they can have a rocket ready to launch. Today, that can be pretty slow, but even now, if you're lucky enough to discover a need for something just a few days before a routine resupply launches, you can get what you need in a few days. There's a crew or cargo trip to the ISS most months.

For the moon, the only difference is the cost of the launch and a couple days' travel time. The Apollo missions were pretty risky, lacking in backup options, but they were also short. A moon base with a routine resupply schedule would be much safer.

There is no bail-out or rapid resupply option from a Mars mission. If you start on a there-and-back mission, you either do or you die. As soon as you've boosted on the outbound leg, you have lost the ability to turn around and come back. You're not coming home for three years, and you're not getting resupplied for two years.
