If Mars can be mined for water (and it looks like it can), there is no reason to make it a one-way trip only. Sending people there with the explicit expectation to die soon speaks of poor planning and not a lot of willingness to export the basic tenets of humanity into space with us. It's a bad precedent, it carries the wrong message about the value of intelligent life, and I'm afraid the mission's limitations also i…
> Scraping together a suicide team and shooting it roughly in Mars' general direction is not the answer to this problem. I think you misunderstand. While the linked article is brief, the one-way plan isn't to send a ship-full of people with suicide pills, but to supply them for the next 40-80 years from Earth. Because of the hilarities of the rocket equation, it is cheaper to send rocket after rocket full of water, b…
Maybe I got caught up in the ridiculousness of the article's sensational tone, but even so there is no technical reason to actually plan on never having return flights. This relates directly to your other statement:
As I wrote in the parent comment, the presence of water on Mars allows for the production of rocket fuel on site. This ties in to where I mentioned extended infrastructure such as a space elevator and a Moon base, because those too will make trips back and forth economical (instead of scraping everything together for a singular "by the skin of our teeth" mission like this one).
I wrote about these points for a reason ;)
