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.

In case you haven’t been paying attention to the news, there was ANOTHER FUCKING OIL RIG EXPLOSION IN THE GULF. Which is why I’m going to now rant about how terrible fossil fuels are. There is nothing good about them as an energy source. They are filthy/pollute the environment, they’re inefficient, and most importantly they are FINITE. We will run out of them. Thankfully this particular explosion doesn’t seem as though it will cause more oil to gush into the Gulf of Mexico, but they aren’t sure yet. I firmly believe that every nation and every energy company in the world should be focusing 100% of their efforts on ways to eliminate the use of fossil fuels as an energy source as FAST AS POSSIBLE. As long as the world is still relying on them, we are speeding straight down a highway that ends with world wars the likes of which have never been seen, and possibly the end of the human race. Our use of fossil fuels will either lead to so much pollution that the entire ecosystem will collapse, or they will become so scarce that the entire world will go to war fighting over them. The very survival of our species could rely on finding a way to 100% renewable energy. Whether it be from the sun, the wind, the ocean, whatever… 100% renewable and clean energy as soon as possible MUST be the absolute goal, and we must stop at nothing to get there. There are lots of other uses for oil than energy, and dare I say those are probably a necessary evil, at least for a while- virtually all plastic is made from it, along with a host of other things, but those pale in comparison to how much is used for energy. I have no doubt technology will get to a point where we don’t need oil for manufacturing either, but energy should be our #1 priority.
Now for my space rant:
A group of spaceflight’s elite sent a letter to Congress yesterday urging the House Science & Technology Committee to revamp its NASA authorization bill. The group, composed of former astronauts, space industry veterans, and former NASA officials, are asking Congress to make their version of the bill look more like the Senate version, which is much closer to Obama’s initial budget recommendation which was announced in February. Unfortunately middle TN’s own Bart Gordon is the head of said committee. Yo Bart- I expect more from you than this. Look at the facts- Obama is right! I’ve said this many times on here before and I’ll say it again: NASA needs to focus its efforts on exploration beyond low-earth orbit and the moon. The private spaceflight industry is more than capable of taking over the job of getting our astronauts to and from the International Space Station, and can be capable much sooner than NASA could using its currently-under-development Constellation Program. But they need the help of NASA in the form of $$$. Less $$$, mind you, than we would spend on Constellation. We will never see the kind of innovation and progress again that we saw from NASA in the 1960’s unless their goals are ambitious and lofty. Putting a man on an asteroid and eventually on Mars should be the new main goal of NASA’s manned spaceflight program, and exploring the moons of Jupiter and Saturn should be the main goal of the unmanned (robotic probe) programs. Those are the kind of ambitious goals that will bring back the kind of innovation and tenacity of the 1960’s. Only this time it will be scientifically driven, not driven by a race to get to the moon before the Russians.

Today I’m simply going to point you in the direction of Nashville Cream to see what’s going on show-wise this weekend. It’s looking like a pretty good one. This is all so I can briefly talk about more science, since this week had only one science-related post.
Buzz Aldrin has stayed somewhat in the spotlight after he became the 2nd man to walk on the moon in 1969. In addition to recording a rap song with Snoop Dogg, Talib Qweli, Quincy Jones, and Soulja Boy, he founded a non-profit organization called ShareSpace and has has published articles criticizing NASA for not focusing on manned exploration beyond our own moon. Just a few days ago he published an article on AOL along those same lines, but this time outlining his idea for what NASA should do next. Mainly he agrees with Obama’s plan to look to private space companies for ferrying cargo and astronauts to the ISS and low Earth orbit. But he proposes that if NASA focuses its effort on Mars, we can get there by the summer of 2019. He wants NASA to continue using the space shuttles to carry leftover space station parts and modules into orbit, where they would then be assembled into an “Exploration Module” prototype, which would be a precursor to a fully fleshed-out version, capable of taking a crew to Mars. There are a lot of details missing here, such as whether or not this EM is supposed to land on Mars or just orbit it, and if it’s supposed to land, where the crew would get the supplies needed to survive, and of course the big question would be: how do they get back? Regardless, I think it’s great that he’s continually putting ideas out there. I don’t necessarily think that he’s even trying to present a technologically feasible, functional plan… more that he’s just trying to get people thinking in a different direction. And even though this is VERY old news, it’s worth posting this video of him punching nutbag, anti-science, anti-reality filmmaker Bart Sibrel in front of a Hollywood hotel in 2002, after being confronted by him. FUCK YEA BUZZ ALDRIN! (Via Discover Blogs)
I must also take this opportunity to point that some scientists really DO have a sense of humor. According to i09, a physics student has asked the International System of Units to call 10 to the 27th power “hella.” That means that a distance of 10 to the 27th meters would be a hellameter. That’s pretty close to the current estimated size of the universe (it would be 1.4 hellameters, to be exact), thus we could officially say that the universe is “hella big.”
Have a great weekend!
