20 years ago it would have been unthinkable to find water in any other planet in the solar system. Mark my words: in 20 years, we'll find extremely simple proto-bacterial life in Mars and in many other planets.

Not exactly true. Water on Mars has been thinkable for quite some time: https://en.m.wikipedia.org/wiki/Chronology_of_discoveries_of...

Yeah well, in the 19th century it was believed there were supposed to be canals up there :).

I was talking to an oncologist yesterday. Her biggest frustration is that Silicon Valley billionaires are spending billions upon billions to send things to space, when there are serious problems on Earth that could be fought, most importantly cancer. It’s hard to argue with her. $400B/yr would fund a lot of research that would benefit humanity a lot better than a coordinated mission to Mars, even though it would be v…

Money is going into biotech fortunately though. Sam Altman started nudging YC towards biotech a few years ago (one article example https://www.wired.com/2015/11/y-combinator-sam-altman-interv... ) and to date has funded the following companies directly involved in cancer research and treatement: Cambridge Cancer Genomics, Oncobox, Mednet, HistoWiz, Luminist, iSono Health, Notable Labs. And I agree, cancer needs figur…

> What I'm more upset about is people spending obscene fortunes on Farmville, World of Warcraft gold, Candy Crush EleventeenNinenty4 Now With Extra Bedazzle, Fortnight etc. Energy, agriculture, medical, space are often neglected in favor of the iPad fruit of the month app of the week. It is extremely frustrating.

I'd like to think that this is a transfer of wealth from idle hands to productive hands, since I have to assume that at least a portion of the business owners behind those cash machines you mention won't just sit on a montain of money, but rather reinvest it in something. But perhaps I'm too optimistic.

For any exploratory drilling, or covering any real amount of ground, you need humans. For reference, Opportunity Rover has only traveled 45 km/28 mi in 14 years. A human can collect more specimens in a day than ALL of the rovers have to date. If we remove this year's launch window, you have 10 minimum-energy launch windows in the next 21 years. 2020, 2022, 2024, 2026, 2029, 2031, 2033, 2035, 2037, 2039. If we could g…

That's a mainstream argument against space exploration. We could then apply it to, "we could try to feed everybody before developing new medication for the rich"... We can tackle many problems at once and we have to ask ourselves : what's the goal of humanity ? Also : are we safe forever on Earth ?

Fighting cancer is being the little Dutch boy sticking your finger in a dam. Adding a decade or so at the end of people's lives is great, but bodies break down, and you're going to be fighting a constant rear-guard action. Getting off this rock is the first step towards getting all of our eggs out of one basket.

> Getting off this rock is the first step towards getting all of our eggs out of one basket. Yes it is, but why should I care whether all of our eggs are in one basket, or two baskets, or a million baskets? The survival of the human race as a whole is not a concern of mine.

Then why do you expect anyone to value your opinion on what to do with human-race-as-a-whole-scale resources?

Yeah, can we fight "uncurable" autoimmune diseases that affect young people as well please ? I'd appreciate it :(

I think if we in the U.S. stopped killing people in senseless wars, we could use some of the trillions we spend on that to both fund medical research and fly to Mars. But that's obviously a fantasy.

Then again, for the 700 billion dollars defense budget you'd get free universal healthcare and higher education for all of the US — AND would still have a few dozen billions to spare on cancer and Mars expeditions... but who in their right mind would want that?

Silicon Valley billionaires are spending $400B/yr on space travel? Where is all this money going?

There are populations of humans on this planet that have very low cancer rates. All we have to do is adopt their lifestyle. Eat right and exercise. That’s probably 90% of it right there. Don’t need to spend any money.

This is a false dichotomy that always annoys me. It is entirely possible that by spending $400B to safely send people to Mars and live there, especially in a moderately high radiation environment, that we will discover EXACTLY the mechanisms that send cells into cancer states and how to reverse that so they stop. Otherwise we're going to have colonists getting cancer and dying too quickly. Then not only do we get to…

It's also entirely possible that the cure for all forms of cancer is a diet consisting entirely of frosted flakes, and that spending $400B researching the effects of all-cereal diets would also discover the cure for cancer. However, it's far more likely that $400B in cancer research will do more for curing cancer than hoping for side effects from $400B in other research.

Imagine giving someone 200 years ago $400B for cancer research; what do you think it would have happen? Do you think they would have found the cure? No. The same thing happens today, $400B may do nothing big for cancer research and what's needed to advance in that area its time; decades (maybe centuries) of advancements in many fields that are not directly related to cancer research but given enough time those advancements will be used together to find a cure (e.g. map the entire DNA; nanorobots, etc)
