ikenbot: VISIONS: NASA Plans To See the Aurora In A New Light On a cold February night in Poker Flat, Alaska, a team of scientists will wait patiently for the exotic red and green glow of an aurora to illuminate the sky. Instead of simply admiring the view, this group from NASA’s Goddard Space Flight Center of Greenbelt, Md., and The Aerospace Corporation of El Segundo, Calif. will launch a sounding rocket up through the Northern Lights. The rocket could launch as early as the night of Feb. 2, 2013, but the team has a two-week window in order to find the perfect launch conditions. Image: Swirls of green and red appear in an aurora over Whitehorse, Yukon on the night of Sep. 3, 2012. NASA’s VISIONS sounding rocket will study what makes the aurora, and how it affects Earth’s atmosphere.

Although the rocket will survive only fifteen minutes before splashing down in the Arctic Ocean, the information it obtains will provide answers to some long-standing questions, says Doug Rowland, who is the VISIONS principal investigator at Goddard. VISIONS will study how oxygen atoms leave Earth’s atmosphere under the influence of the aurora. Most of the atmosphere is bound by Earth’s gravity, but a small portion of it gets heated enough by the aurora that it can break free, flowing outwards until it reaches near-Earth space. The atoms that form this wind initially travel at about 300 miles per hour — only one percent of the speed needed to overcome gravity and leave Earth’s atmosphere. “This oxygen would normally never gain enough energy to leave the atmosphere,” says Rowland. “On the other hand, at very high altitudes, satellite experiments have measured oxygen atoms moving faster than 50 miles per second. These experiments have shown that if oxygen can reach these high altitudes, there are plenty of ways for it to gain even more energy, in which case the oxygen atoms can escape near-Earth space entirely. What we don’t know is how the oxygen gets enough energy to fight against gravity and reach the higher altitudes where these slingshots are active.”

samspratt: SAM SPRATT’S SPRING PORTRAIT CONTEST/CUSTOM PORTRAIT/SIGNED PRINT GIVEAWAY! Spring is around the corner which means as thanks to you for following me here, as usual—I am giving TWO of you the chance to win a custom portrait made by me, custom-tailored to your heart’s desire. Free, no strings attached.  The rules are simple, but read them so you can win. What You Get: A Web-resolution (1100 pixel) custom portrait, tailored to your most bizarre of requests. You can get a very traditional portrait done or as outlandish as you can dream. Zombies, Hipsters, Pirates, Ninjas, Superheroes, Robots, etc. are all fair-game themes in which you can have yourself transmogrified in painted form. ADDITIONALLY, I’ll be giving 3 runner-ups their choice of a 13”x19” signed velvet archival print. Choices are: Sherlock, Ron Swanson, and Inspector Spacetime. How to Enter: FACEBOOK: Simply comment on the following facebook post. You get an extra entry if you click the “share” button and post it to your wall. ( Sam Spratt - Facebook Contest ) TWITTER: Follow http://twitter.com/#!/SamSpratt and tweet the following phrase verbatim on twitter:  “ Entering to win a custom portrait #painting from @samspratt’s portrait contest! https://www.facebook.com/sam.spratt ”   This also counts as an entry. TUMBLR: Just reblog/like this post! How long this will last: This contest will run until April 6th, 2012.  You all are the best! Good luck and thanks again to all who follow my little slice of artwork on the web. NOTE: You must be a follower or subscriber at the time of the win.  Why all this? Well, you’ve gotta write a big check with quite a few zeros at the end of it to commission art from me—and call me crazy, but I firmly believe that in a perfect world, people *should* get to own art AND do things like “pay rent”, “eat food-like substances on occasion”, and maybe even “continue to live”. Two of you can do that, the rest of you… you’re screwed. Sincerely, <3 Sam
