The third Copernicus Sentinel-1 satellite was launched on 5 December on a Vega-C rocket from Europe’s Spaceport in French Guiana: a key step in restoring Europe’s independent access to Space and in monitoring climate change. Sentinel-1 data contributes to numerous Copernicus services and applications, including Arctic sea-ice monitoring, iceberg tracking, routine sea-ice mapping and glacier-velocity measurements. Sentinel-1 data are freely available via the Copernicus Data Space Ecosystem. 👉 https://ow.ly/jGif50UnfBF

Once we develop this new suite if electromagnetic technologies the entire planet will seem like one small neighborhood of the interplanetary civ. We can get to mars in less than a week once the thrusters are functional

California's Line Fire Creates Pyrocumulus Clouds, Triggering Its Own Weather System The Line Fire in California has been burning so intensely that it created its own weather system. Pyrocumulus, or "fire clouds," formed over the fire on Monday, captured by NASA’s Landsat-8 satellite. These clouds develop from intense heat sources, like wildfires, as hot air rises rapidly and cools to form clouds. Unlike typical clouds, pyrocumulus clouds are darker due to the smoke and ash they ingest. The satellite showed massive pyrocumulus clouds forming over the fire, sending smoke and ash high into the atmosphere. Later, these clouds transformed into pyrocumulonimbus, which produced lightning and rain. While rain could aid firefighting, the winds and lightning may also ignite new fires in dry areas. #LineFire #WildfireWeather #Pyrocumulus #FireClouds #CaliforniaFires #NASA #Firefighting #ClimateChange #ExtremeWeather #FireSeason

What’s the best technique to detect Travelling Ionospheric Disturbances? This is exactly what we investigated in this recent paper published in Journal of #spaceweather and #spaceclimate of the European Space Weather and Space Climate Association (E-SWAN).

Today, our colleagues at NASA Jet Propulsion Laboratory gave an update on the joint JPL + AeroVironment investigation into Ingenuity's final flight. After pouring over telemetry and imagery and analyzing potential failure modes, we have a clear idea of the root cause of the failure that ended of Ingenuity's 72nd flight on Mars. When flying over the sand dunes of Valinor Hills, Ingenuity’s visual navigation system was not able to find and track enough distinct features to keep track its position and velocity, and the vehicle effectively lost the ability to navigate. There are a few plausible paths for what happened next. Most likely, a blind descent led to a hard emergency landing, which generated forces that snapped all four rotor blades at their weakest point. The original hypothesis that the tips of the rotor blades struck the surface did not hold up as we reviewed more information. We know that on the previous flight, Ingenuity had suffered a similar degradation of its navigation which led to a hard landing that was about ~5x what the helicopter was designed to sustain. We don't have telemetry to tell us the exact landing velocities that happened during the failure on flight 72, but we do have visual indications that Ingenuity was moving quickly, with a high level of horizontal velocity as well. When exposed to the kinds of gyroscopic forces that would accompany such a hard landing, one would expect the rotor blades to break right where they are in fact broken on Ingenuity now. In the parlance of our industry, we talk about this as an accident investigation -- but in an important way, pushing Ingenuity beyond its limits was not accidental. Once Ingenuity had completed its original five-flight mission and had showed it was possible to fly an aircraft on Mars, a big part of Ingenuity's job became finding out what *wasn't* possible. Eventually, Ingenuity met a challenge that it simply wasn't up for -- and even then, the vehicle remains remarkably intact, continuing to gather information for scientists as a weather station. In the end, the limitation that ended the flying portion of the mission stemmed from a navigation system that was designed for a very straight-forward five-flight mission and that way overperformed -- and which would be relatively simple to upgrade for future flights. As co-designers of Ingenuity, my team at AeroVironment are incredibly grateful for the excellent partnership we have with JPL, and we are honored to have played a part in this remarkable mission. I've said it before, but Ingenuity's greatest legacy will be as the forerunner to many aerial vehicles to follow. My vision for the future involves dozens of helicopters flying on Mars in the near future, each of which will owe a debt to Ingenuity! Thanks to Theodore (Teddy) Tzanetos, Håvard Fjær Grip, Travis Brown, and Lindsay Hays for doing an excellent job of communicating this today! https://lnkd.in/eMD3JRmF

📢 📢 📢 Excited to share that my work for part of my PhD on estimating Arctic freeboards and derive snow depth from dual-frequency altimetry (laser and Ku-band) along the CryoSat-2 and ICESat-2 (CRYO2ICE) orbits for winter seasons 2020-2022 has been published! A great thanks to my amazing co-authors! 🛰 ❄ Two main take-aways are: 🔻 #CRYO2ICE snow is thinner than other snow depth composites, most pronounced in late winter season and over multi-year ice (perhaps due to the complexity of snow and ice pack?) 🔻 Uncertainties range from 7-16 cm. #CRISTAL requirements (upcoming - and first ever - spaceborne dual-frequency altimetry mission expected to launch in 2028 which shall derive snow depth from dual-frequency altimetry) states 5 cm along 25 km segments! ... But you can read a short thread on the main results here, if you're interested in learning a bit more on what we can see on the Arctic sea ice when using near-coincident laser and radar altimetry from space: https://lnkd.in/dBfPZSNV Can't get enough of #CRYO2ICE? 🛰 In case you're interested in having a look at the full study, find the research article here in the current issue of Earth and Space Science (AGU): https://lnkd.in/dfV4cGTR

2023: A Year of Record-Breaking Heat and Extreme Weather NASA and NOAA just released the final data for 2023 global temperatures, and it was a year for the history books! Not only did the Northern Hemisphere experience its hottest summer on record, but the Southern Hemisphere saw its warmest winter ever. These record temperatures weren't the only story. The US alone faced 25 separate billion-dollar weather disasters in 2023, including the first-ever tropical storm watch in Southern California, devastating wildfires in Canada impacting air quality across the East Coast, deadly tornadoes in the Midwest, and record-breaking heatwaves in the Southwest. Join the conversation! What questions do you have about the 2023 climate trends and their impact on our planet? #ClimateChange https://lnkd.in/efpkUA5x #NASA #NOAA #inergency https://lnkd.in/eQmXXww3 #egreenews #Evideosecurity

The MARS allows, among other things, the installation of a rear axle with wheel swivel for operation in confined urban or off-road conditions or the possibility of individual wheel clearance adjustment.
