GOOD MORNIN' ALL
A New NASA Conspiracy: Does This Photo Show a Man Fixing the Mars Rover?
by Katharine Trendacosta 3 Feb 2015
Look at the above image. Doesn't that shadow look like a man in a spacesuit of some sort working on the Curiosity rover? Which is supposed to be on Mars, and not where humans can mess with it?
The image is from 2012, and at least one person seems to think that this means that the Curiosity never left Earth. Or that there's more happening on Mars than we've ever been told. The Huffington Post points to ufologist Scott Waring's UFO Sightings Daily, which explains:
Someone who wants to remain nameless has found a shadow of a human-like being messing with the Mars Curiosity rover. The person has no helmet and their short hair is visible and in high detail. The person has on air tanks on their back and a suit that covers most of the body except the hair. This leaves us with three confusing thoughts.
1st Is this proof that the rover is on Earth and not Mars and humans are cleaning it off and performing maintenance?
2nd Is this proof that humans are living on Mars in abandoned alien bases? (i.e. Gary Mckinnon hacker said he found such evidence on US govt computers).
3rd Is this proof that alien are messing with the rovers?
Could be. Could be. Or, there's this image from 28 seconds later, which shows a different shadow:

An ultrafast camera films light at light speed
by Ashley G. Smart February 2015
Exploiting a strategy known as compressed sensing, the camera can capture video at 100 billion frames per second.
The human visual system can perceive only about 10 distinct images per second. So to record everyday life as we experience it, a standard video capture rate of 24 frames per second (fps) more than suffices. But many physical phenomena unfold faster than the eye can see. To record them, researchers seek ever-faster cameras.
Now Lihong Wang and coworkers at Washington University in St. Louis have developed a camera that can record at 10 11 fps, good enough to capture the movement of light at millimeter length scales. The camera marries streak photography, an ultrafast imaging technique previously limited to filming in one spatial dimension, with compressive sensing, a mathematical strategy for reconstructing an entire scene from an incomplete set of measurements. “The camera has countless potential applications,” comments Mário Figueiredo of Instituto Superior Técnico in Lisbon, Portugal. “It’s sort of like a microscope for time.”

The White House Wants To Go To Europa
By Marcus Woo
02.04.15 | 10:26 am
Earlier this week the White House made public its budget requests for 2016. It’s a little bit of Washington kabuki—Congress always adjusts the budget one way or the other. But buried inside the $18.5 billion budget request for NASA was an interesting tidbit: $30 million for a mission to the Jovian moon Europa, every space nerd’s favorite target in the search for extraterrestrial life.
In other words, if this new funding goes through, it’ll mean that NASA is finally, officially onboard with a mission to the ice-crusted world where alien monoliths took over in Arthur C. Clarke’s 2010. In other other words: Let’s go to Europa! “This is a big deal,” says Casey Dreier, the director of advocacy at the Planetary Society, which has been lobbying for this mission for more than 15 years. “This budget basically fills in the missing piece that will enable this mission to go forward.” The new budget request also says that the White House plans to ask for even more money in the next few years, and because the mission is now an official project, says Dreier, civil servants can work on it and NASA can start making long-term contracts for further planning.
So what would the mission look like? Europa’s icy shell gives it the smoothest surface of any world in the solar system. But shifting cracks and other evidence suggest that that below that frozen surface lies an ocean—a watery one. And where there’s water, life may follow. Researchers have wanted to get there for decades—the current best idea for how is a 15-year-old concept called the Europa Clipper. “What we’ve been looking at is a multiple flyby mission,” says Bob Pappalardo, the mission’s project scientist. Under the current plan, a spacecraft will orbit Jupiter, not Europa—but it’ll zip past the moon 45 times in three years—venturing as close as 16 miles to the surface every couple of weeks.
Scientists are still hashing out what kinds of instruments will be onboard, so Pappalardo can’t say which exact ones will end up going to Europa. But one of the main goals will be to measure the moon’s magnetic field, which would tell scientists how salty the subsurface ocean is. Dissolved minerals (like salt) allow the ocean to conduct electricity—which means it’d have a magnetic field a sensor could read. Or more speculatively, in 2013 the Hubble Space Telescope spotted what looked like 125-mile high geysers spewing water from Europa’s south pole. Maybe a probe could actually fly through one and sample the water. Radar could reveal how thick the frozen crust is, and other instruments could measure the chemicals in Europa’s wispy atmosphere. High-resolution cameras will take pictures of the cracks that crisscross the surface, hoping to figure out whether it’s actually the case that the ice flexes and breaks because of that still-hypothetical ocean. And they’ll also scope out possible spots to send a future lander.
That’s the real brass ring, of course—if you want to find aliens. “If someone comes up with a clever way to point to life with multiple flybys, that will be wonderful,” Pappalardo says. “But that will probably take going to the surface.” That’s why Earthbound experiments like the work at Lake Vostok in Antarctica are so interesting to planetary scientists—cracking through 2.5 miles of ice to get to a liquid lake below without contaminating it may turn out to be highly relevant expertise someday.
When that’ll happen, though, is another question. The price tag for something Europa Clipper-like looks to be about $2 billion, so it’ll take a few more years of budgets to get it all together. A mission with a lander would be much more expensive. An orbiter might still be a possibility, but “it’s a riskier and more expensive approach than making many flybys,” Pappalardo says. It would take a year and a half after arriving at Jupiter just to get into Europa’s orbit, requiring lots more fuel and exposing the spacecraft to radiation that could fry its instruments.
However the details turn out, a Europa mission could launch as soon as the mid-2020s, said David Radzanowski, NASA’s chief financial officer, in a press briefing on Monday. Which means it won’t actually get to Europa until around 2030. But if all goes as planned, those 15 years will fly right by.
Fight For Your Right to Repair Your Car What does copyright have to do with car repair? As ridiculous as it sounds, sections of the Digital Millennium Copyright Act could actually prevent car owners from looking under the hood—or even protecting themselves from vulnerabilities and malware. But there's something you can do.
Modern cars come with dozens of onboard computers that run potentially copyrighted code put there by manufacturers. You or your mechanic may need access to that code for repairs and customization, and researchers need access to discover and fix software problems that threaten your safety and the security of your car. But when manufacturers add technological restrictions that keep you from even looking at that code, it may be unlawful under the DMCA to work around those restrictions.
We can clear up the dark legal cloud that hovers over car repair and research. Every three years, the Librarian of Congress and the Copyright Office can grant exemptions to these DRM rules, and EFF is fighting for exemptions that would make it clear that copyright can't stand in the way of car repair. Sign below to support our efforts to tell the Copyright Office: when it comes to car repair, let's kick the DMCA to the curb—and put owners back in the driver's seat.

Historically, he adds, Burning Man was “a great leveler”—nobody in Black Rock City cared who you were. The prevalence of costumes allowed the rich and famous to mingle with the masses. “For a lot of captains of industry and the celebrities, it was a chance for them to go and be a normal person at the party like anybody else,” says Outtrim. “But bringing in servants is where it’s become a bit of a problem. It’s pushing buttons related to class war in San Francisco.”
Me thinks Burning man lost it's soul a while ago
