Dennis Tito to send a married couple to Mars in 2018, in a spaceship lined with their own poop!

Billionaire Dennis Tito, who is known as the first-ever space tourist, unveiled on Wednesday Inspiration Mars, a plan to launch two people, likely a married couple, on mission to Mars in 2018. The best part: the spaceship in which they travel will be lined with the couple’s own shit! This whole idea sounds incredibly far-fetched, and I even mentioned my doubt of its feasibility last week when the “teaser” press release about the press release made some headlines. It still sounds kinda crazy because of the part about the shit (I’ll get to that in a minute), but they left out one really important detail last week- the couple won’t actually be landing on Mars, just flying around it once in a spacecraft. Actually landing on Mars is really, REALLY, REALLY hard in terms of engineering and feasibility, but just sending a couple of people on a slingshot around it? Not quite as hard. Tito is very committed to making it happen, and is even prepared to fund the first two years of mission development, so this could work. More details on the project can be found in this New Scientist article.

Now, as far as the shit goes… it’s really not as crazy as it sounds. One of the biggest challenges to deep space exploration like this is that the crew members will get bombarded with genetic mutation-inducing cosmic radiation. We’re talking X-rays and Gamma rays, along with the ever-present solar wind of ions. It’s practically a death sentence if you can’t shield the crew from all that, and as it turns out, dried up human waste is actually pretty good at just that! Rather than just jettison it into space, why not seal it up in (fully sanitary, of course) bags and line your spaceship with it to add to the shielding of your spaceship? Astronauts onboard the ISS are already using a reactor system that recycles the water from their urine, and gross as it may seem, this mission will do that AND recycle the moisture from their poop. When you’re going on a 500 day mission to Mars, you have to be very resourceful. For more on the poop shield, see this other article on New Scientist.

In other Mars-related news, unfortunately the Curiosity Rover has suffered a computer glitch which has forced the team to switch everything over to the rover’s backup computer. In short, they will slowly reboot all the rover’s systems from the backup computer, make sure everything checks out, and continue with normal operations. Meanwhile, another team will investigate the problem with the primary computer and attempt to fix it so that it’s operational and can be used in case the backup computer fails.
