Galactic cosmic rays are high-energy particles that originate from outside the solar system that likely come from explosive events such as a supernova. They are bad news for cameras in space -- damaging the sensor and spoiling photos -- so Nikon made special firmware for NASA to limit the harm. Pettit tells PetaPixel that Nikon changed the in-camera noise reduction settings to battle the cosmic rays -- noise is unwanted texture and blur on photos. Normal cameras have in-camera noise reduction for exposures equal to or longer than one second. This is because camera manufacturers don't think photographers need noise reduction for shorter exposures because there's no noise to reduce. But in space, that's not true. "Our cameras in space get sensor damage from galactic cosmic rays and after about six months we replace all the cameras but you still have cameras with significant cosmic ray damage," explains Pettit. "It shows up at fast shutter speeds, not just the slow ones. So we got Nikon to change the algorithm so that it can do in-camera noise reduction at shutter speeds of up to 500th of a second." Pettit says Nikon's in-camera noise reduction "does wonders" for getting rid of the cosmic ray damage and that "trying to get rid of it after the fact is really difficult." That's not the only special firmware feature that Nikon makes for NASA; photographers who shoot enough photos know that the file naming system resets itself eventually which is no good for the space agency's astronauts. "The file naming system on a standard digital system will repeat every so often and we can't have two pictures with the same number," explains Pettit. "We'll take half a million pictures with the crew on orbit and so Nikon has changed the way the RAW files are numbered so that there will be no two with the same file number." https://lnkd.in/e3rWHnZp

As you may know, the total solar eclipse will pass over our region Monday April 8th, between the hours of 2:08 pm and 4:35 pm. 𝗧𝗶𝗽𝘀 𝗳𝗼𝗿 𝘃𝗶𝗲𝘄𝗶𝗻𝗴 𝗮 𝘁𝗼𝘁𝗮𝗹 𝘀𝗼𝗹𝗮𝗿 𝗲𝗰𝗹𝗶𝗽𝘀𝗲 Except during the brief total phase of a total solar eclipse, when the Moon completely blocks the Sun’s bright face, it is not safe to look directly at the Sun without specialized eye protection for solar viewing. NASA has outlined a few do’s and don’ts: • Do not look directly at the sun • Do not use homemade filters or ordinary sunglasses; even very dark sunglasses are not safe for viewing the sun • Use special solar filters, such as eclipse glasses or handheld solar viewers, to view the eclipse • Read and follow recommended solar filter instructions and supervise younger children • In any stage of the eclipse, do not look at the sun through a camera, telescope, binoculars, or other optical devices, and never use solar filters with these devices, as concentrated solar rays will damage them and can cause serious eye injury • Inspect your solar filter before use; if it is scratched or damaged, discard the filter If you should experience discomfort or vision problems following the eclipse, please visit your local doctor of optometry for a comprehensive eye examination. Please stay safe and enjoy the event. #solareclipse #solareclipse2024 #staysafe

This is definitely the wrong type of #KillSwitch. The kind that is self inflicted. The hardships up there : speed, balance, center of gravity, boosters, reduced atmosphere density, terrain incline, and then again, speed. That's why you would have needed laser guidance (LiDAR) at its fittest. Instead [...] Two lucky breaks and a stroke of genius saved Intuitive Machines' moon-landing mission on Thursday. A serendipitous moment, a NASA experiment, and frantic, innovative software engineering rescued the company's Odysseus lander from what could have been a catastrophic error — a switch that didn't get flipped before launch. That simple mistake disabled the lasers designed to guide the spacecraft to a flat, safe spot for landing, Intuitive Machines cofounder and CEO Steve Altemus told reporters on Friday. [...] So we (or at least I was) were kinda enthusiastic about the self landing protocol with just a bunch of pilots in C&C, watching monitors from earth. Too bad they clapped 👏 #TooSoon. I'm as sad as I'm happy and I can only add that it is a sign of our times, to the absurd chain of failures in our global space programs. Mixed feelings really. Not some good times at all, if we measure against how much water has passed under the bridges since the original 70's space missions. Japan - https://lnkd.in/d5SKsZ6C India - https://lnkd.in/dG8CgQqM Russia - https://lnkd.in/dBJpKQ_7 Least but not last, this private mission -> https://lnkd.in/dAZAn-_g Are we actively making ourselves the weakest link in human evolution? + Or it's just "by chance" that one ship #crashed, two Landers #flipped at touchdown, and two others #malfunctioned? + Makes you think. 🧠 Or does it? Whoever is worried about the fact that we became the "Wall-E" version of ourselves: maybe you are right. Doesn't feel good, if we really plan to give the control stick to AI, moving forward. The Human-In-The-Loop and the Human oversight are intended to correct the software that takes decisions, not to hinder it, intuitively. Are these signs the prelude to #InevitableDoom? Some might start becoming superstitious.

Day 1451: Why is there no sound in space? You cannot hear any sounds in near-empty regions of space. Sound travels through the vibration of atoms and molecules in a medium (such as air or water). In space, where there is no air, so sound has no way to travel. Sound, like light or heat, is a wave. However, one major distinction is that, unlike light or heat (radiation), sound needs a medium to travel. Sounds require the presence of molecules or particles to travel from one region to another. It is the outward vibration of these vagrant particles in the periphery of the source that accounts for the production and spreading of sound waves. A particle sauntering right next to a plucked string of a guitar is plunged into motion. This particle jiggles and transfers its kinetic energy to its neighbor, which then transfers it to his neighbor and so on, until the wave reaches the receptors in our ear and is perceived as a note. Therefore, the reason why sounds do not travel in space is because there are no particles to disturb in the first place. That being said, what about the gas particles, remnants from supernova explosions and other dust particles? Can’t they propagate sound? Oddly, no. These particles, unlike the particles on Earth, aren’t close enough or, to put it more elegantly, they aren’t compressed enough to communicate. Remember that space is virtually a vacuum, so the particles from the explosion are dispersed immediately and consequently aren’t dense enough to carry sound. Technically, a cloud of dust could carry sound, but the amplitude would be tremendously minuscule and practically inaudible to human ears. To an astronaut outside a spaceship, the spaceship’s explosion would be a confusing visual of blinding heat and light, but it would be devoid of any sound, a silent film. For anyone accustomed to the physics of Earth, this might induce cognitive dissonance. However, because the air inside the spaceship is compressed, the explosion could be easily heard by an astronaut inside. This is also why astronauts cannot shout out to their partners and must use special equipment that converts sound to radio when sending a message and radio to sound on the receiving end. So, no, there’s no sound in space. #learnonethingaday

Day 1348: How is a sonic boom caused? Sonic boom is an impulsive noise similar to thunder. It is caused by an object moving faster than sound -- about 750 miles per hour at sea level. An aircraft traveling through the atmosphere continuously produces air-pressure waves similar to the water waves caused by a ship's bow. When the aircraft exceeds the speed of sound, these pressure waves combine and form shock waves which travel forward from the generation or "release" point. As an aircraft flies at supersonic speeds it is continually generating shock waves, dropping sonic boom along its flight path, similar to someone dropping objects from a moving vehicle. From the perspective of the aircraft, the boom appears to be swept backwards as it travels away from the aircraft. If the plane makes a sharp turn or pulls up, the boom will hit the ground in front of the aircraft. The sound heard on the ground as a "sonic boom" is the sudden onset and release of pressure after the buildup by the shock wave or "peak overpressure." The change in pressure caused by sonic boom is only a few pounds per square foot -- about the same pressure change we experience on an elevator as it descends two or three floors -- in a much shorter time period. It is the magnitude of this peak overpressure that describes a sonic boom. The Concorde was famous for causing these sonic booms, as are fighter jets. Hence a ban on commercial supersonic flight over land had been set. NASA hopes the ban on commercial supersonic flight over land can be lifted by replacing the loud sonic boom with a softer sonic “thump.” A sonic boom happens when the shock waves from an object traveling through the air faster than the speed of sound merge together before they reach the ground. Sonic booms generate enormous amounts of sound energy, about 110 decibels, like the sound of an explosion or a thunderclap. Through the unique design of the X-59 Quiet SuperSonic Technology (QueSST) airplane, NASA aims to reduce the sonic boom to make it much quieter. Engineers with the agency’s Commercial Supersonic Technology (CST) project recently used a small-scale model of the X-59 in NASA Glenn’s 8- by 6-foot Supersonic Wind Tunnel to visualize the agency’s boom-reducing technology and validate its boom-predicting capabilities. #learnonethingaday
