Woman Criticized for Taking Selfie on Top of Her Car as It Sinks into a Frozen RiverLynda Douglas shares this photo of a woman who has her priorities straight. It’s quite cold in Ottawa, Ontario—currently 5° American. A woman accidentally crashed her car into the Rideau River, which is frozen enough to be dangerous, but not enough to hold up the weight of a car. As residents attempted to reach her with kayaks in order to rescue her, the woman climbed on top of the trunk of her car and took a selfie.MSN News reports that the woman accepted a ride on a kayak to the shore, but refused a medical assessment by waiting paramedics. Police charged her with the dangerous operation of a motor vehicle.-via Dave Barry#selfie #Canda

Japanese Man Took a Selfie as Mount Aso Volcano Erupted Behind HimThis Japanese hiker has probably crossed a monumental feat off his bucket list, as he was able to snap a photo of himself in front of an erupting volcano.According to Japanese broadcaster RKK Kumamoto, the man decided to hike near the summit of  Mount Nakadake, one of the five peaks of Mount Aso, which happened to erupt as he was about to take a selfie. “When I was looking through [my camera], the white smoke turned black, and after about three seconds, I heard a swooshing sound,” the man told RKK, according to Futurism. “I was scared. I never thought I would encounter such a thing.”#selfie #Volcanos #OddTiming #MountNakadake #MountAso #Volcanos #VolcanicEruption #Photographyimage credit: u/sinmantky via Reddit / Futurism

So How Did NASA's Perseverance Mars Rover Take Selfies Anyhow?For you and I, taking a selfie is quick and simple - just point the cell phone's camera our way and snap the pic. But how did NASA's Mars rovers like Perseverance and Curiosity do it? It took about a dozen experts, a week to plot the commands, and 62 images for the rover to make it happen.From NASA:Like the Curiosity rover (this black-and-white video from March 2020 show how it takes a selfie), Perseverance has a rotating turret at the end of its robotic arm. Along with other science instruments, the turret includes the WATSON camera, which stays focused on the rover during selfies while being angled to capture a part of the scene. The arm acts like a selfie stick, remaining just out of frame in the final product.Commanding Perseverance to film its selfie stick in action is much more challenging than with Curiosity. Where Curiosity’s turret measures 22 inches (55 centimeters) across, Perseverance’s turret is much bigger, measuring 30 inches (75 centimeters) across. That’s like waving something the diameter of a road bike wheel just centimeters in front of Perseverance’s mast, the “head” of the rover.JPL created software to ensure the arm doesn’t collide with the rover. Each time a collision is detected in simulations on Earth, the engineering team adjusts the arm trajectory; the process repeats dozens of times to confirm the arm motion is safe. The final command sequence gets the robotic arm “as close as we could get to the rover’s body without touching it,” Verma said.#NASA #MarsRover #PerseveranceRover #Mars #selfie #JPL
