See Earth Breathe: New Tools Monitor Air Quality from Space This animation from NASA's SVS showcases the power of new satellite observations! It tracks air pollution changes over California during COVID-19 lockdown measures. Here's the story: The animation uses data from NASA's Total and Spectral Solar Irradiance Sensor (TSIS-1) to depict nitrogen dioxide (NO2) levels. NO2 is a pollutant primarily emitted from vehicle exhaust. During the lockdowns, significant reductions in NO? are observed across California, particularly in major cities like Los Angeles. This data highlights the potential of space-based monitoring for air quality. By tracking pollutants like NO2, scientists can assess the effectiveness of emission reduction strategies and improve air quality for everyone. #AirQuality #ClimateChange #NASASVS #EarthScience #RemoteSensing #inergency #egreenews #Evideosecurity

This unique vantage point allows for observations of natural phenomena, climate change, and environmental shifts, enhancing our understanding of Earth systems. In addition to photography, the ISS hosts advanced Earth observation instruments, enabling detailed data collection on various environmental factors, such as temperature and vegetation health. This synergy of human observation and technology makes the ISS a vital platform for global scientific research and environmental monitoring. 🌟Recently came across this image online. The photograph looks amazing. 📌Do you think this image is of Earth captured from ISS or it is generated by AI? Image credits: curiosity #earth #space #image #satellite #nasaw

🛰️ Have you ever wondered how the unseen particles in our atmosphere are constantly shaping the quality of the air we breathe? Thanks to advancements in earth science data collection and modeling, we're now able to illuminate the invisible forces, such as air quality, shaping our everyday life. 🌏 This recently released animation, fueled by the powerful GEOS-5 model, sheds light on the patterns behind aerosol transport - and the interconnections between Earths systems. Once airborne, particles like dust, black carbon, and sea salt can travel across continents and over oceans, influencing climate and weather patterns and altering air quality in communities across the globe. 🚀 NASA's GEOS-5 model fuses complex equations with measurements from an array of sources, including satellites, aircraft sensors, and ground instruments to simulate real-world conditions several times a day. Models such as GEOS-5, paired with compelling visualizations, are key to understanding the connections between Earth's systems, and driving informed decision-making.

Continental Heart Monitor: Scientists at the Smithsonian Institution and NASA - National Aeronautics and Space Administration are teaming up to create a new way of visualizing and understanding how pollution impacts daily life. Building a near real-time 3D air pollution map using advanced location intelligence (#GIS) tools from Esri, the TEMPO mission creates a regularly updated, detailed view of pollution sources across all of North America. The update cadence- from ten to 14 times each day- collects data from all parts of the continent, including rural areas lacking ground sensor networks. These collections create a consistent rhythm and understanding of how everything from commuting patterns to weather events can harm vulnerable populations at zip code or neighborhood levels.

NASA's X-59 Aircraft Aims for Supersonic Speed with Minimal Noise Impact. by Clarence Oxford - Los Angeles CA (SPX) Looking ahead, NASA anticipates a long-term deployment of these recording systems, up to nine months, during Phase 2 of the QueSST mission. The lessons learned from the CarpetDIEM flights, including the reduced setup time for recording stations and the coordination with various agencies, will inform the preparation for this next critical phase. NASA's groundbreaking X-59 experimental aircraft, designed to fly faster than the speed of sound while producing a significantly quieter sonic boom, is inching closer to its ambitious goal, thanks to recent advancements in ground recording technology. The agency's Carpet Determination In Entirety Measurements (CarpetDIEM) project has completed pivotal tests to capture these quieter sonic "thumps" from the ground, marking a crucial step toward revolutionizing supersonic flight. Over a 30-mile stretch of desert near NASA's Armstrong Flight Research Center in Edwards, California, researchers successfully set up 10 microphone stations as part of CarpetDIEM flights. These tests were focused on assessing the deployment, operation, and data collection capabilities of a new generation of ground recording systems, essential for the upcoming tests of the X-59. "Forrest Carpenter, principal investigator for CarpetDIEM III, shared insights into the logistical challenges and learning curve associated with these tests. "We're kind of learning how to dance now so that when we get to the big dance, we're ready to go," Carpenter explained. This preparation is in anticipation of the X-59's eventual flights, designed to produce sonic thumps as quiet as about 75 perceived loudness decibels-a stark contrast to the over 100 decibels associated with the Concorde. The CarpetDIEM III testing utilized F-15 and F-18 jets from NASA Armstrong to simulate the X-59's quiet sonic boom through 20 supersonic passes, with one maneuver achieving a noise level as low as 67 perceived level decibels. These efforts are instrumental in validating the X-59's innovative design, aimed at mitigating the disruptive sonic boom that has historically limited supersonic travel over land. https://lnkd.in/dtCdta4Q

How does a new X-59 Quesst, designed and built by NASA and Lockheed Martin’s Skunk Works, fly at twice the speed of sound without creating a loud sonic boom when it breaks the sound barrier? Well, science. It’s been a little over 20 years since the Concord, the last supersonic jet, flew at twice the speed of sound. Now NASA has unveiled a revolutionary experimental supersonic “quiet” jet called the X-59 Quesst ("Quiet SuperSonic Technology") that “is designed to break the sound barrier without the thunderous sonic booms that typically occur when aircraft go supersonic.” According to an article on The Aviation Geek Club website “The X-plane accomplishes this by a tailored design that separates the shock waves that produce sonic booms, making them quieter. The resulting supersonic “heartbeat” is dramatically quieter than the disruptive N-wave boom generated by today’s supersonic aircraft. So it turns out there will be a sound when the X-59 Quesst does break the sound barrier, but it will be a much quieter and muffled sound instead of the loud booming sound from a sonic boom. Among the X-59 Quesst’s many technical innovations is the lack of a forward window. If there’s now front facing windows then how does the pilot actually see where they’re going? The X-59 Quesst “features what NASA calls the eXternal Vision System, or XVS, which consists of a camera and a cockpit-mounted screen that offers pilots an augmented-reality view of what's in front of the jet.” The forward-facing window was removed from the design of the aircraft to “help reduce the sonic boom the aircraft produces.” Flight tests are scheduled to begin this year over populated areas to survey people on the ground to better understand how loud the aircraft really is. https://lnkd.in/dyPNd87Q
