Inspiration Mars

What? I was not aware anything happened today other than SimCity 5 coming out today. If you’re in a similar state, just emerging from your simulation city for the first time since midnight—or just about to go in for the first time after work—here is a quick rundown of some stories you might have missed today.

Astronaut poop doubles as radiation shield in 2018 Mars mission [Laughing Squid]

Inspiration Mars is long-term space mission that will take two astronauts on a 501-day round trip around Mars and back. One of the biggest dangers of space travel is the raw radiation you can encounter in a small space capsule. But the Inspiration Mars team is looking into makeshift radiation shielding to further minimize exposure using everything from bags of food, water, and even...poop. The planning team is convinced that fecal matter would be a great replacement shielding for the cabin as the two astronauts use up the bags of water and food. The only real problem is the smell, of course.

Raspberry Pi turns one, gets a special blue version [Engadget]

The Raspberry Pi is officially one year old, and to celebrate this momentous occasion, the company is shipping out 1000 blue Raspberry Pis. These special edition Pis come printed on blue PCB and come with a matching blue case as well as with a signature by Raspberry Pi co-creator Eben Upton. Raspberry Pi will donate a majority of the blue Pis to charitable causes while reserving a few for competition prizes.

How much would Wikipedia weigh in real life? [Gizmodo]

Wikipedia is arguably the Internet’s greatest information source. There, you can read up on the history of light bulbs, learn more than you ever cared to know about road signs in the United States, and find a biography for just about every comic book character ever. But what if Wikipedia existed outside of the Internet as a real-life encyclopedia? The geniuses behind Vsauce put that question to thought and have come up with concrete numbers. Supposedly just the English version of Wikipedia would require the equivalent of 1759 volumes of the Encyclopedia Britannica and would weigh a total 7000 pounds. Knowledge is power, but it's also really heavy.
