How_a_spacecraft_feels_a_planetary_flyby

The magnetic and particle environment around Mercury was sampled by BepiColombo for the first time during the mission’s close flyby of the planet at 199 km on 1-2 October 2021, while the huge gravitational pull of the planet was felt by its accelerometers.

The magnetic and accelerometer data have been converted into sound files and presented here for the first time. They capture the ‘sound’ of the solar wind as it bombards a planet close to the Sun, the flexing of the spacecraft as it responded to the change in temperature as it flew from the night to dayside of the planet, and even the sound of a science instrument rotating to its ‘park’ position.

      Modeling properties of thunderstorm discharges

      Researchers report detailed physical properties of different types of corona discharges, including single- and multi-pulse blue discharges linked to powerful but short-lived electrical bursts near the tops of clouds. These details provide a reference for further investigation into the physical mechanisms behind these discharges and their role in the initiation of lightning, an important problem in lightning physics.

      An ESA (European Space Agency) instrument used to study thunderstorms, Atmosphere-Space Interactions Monitor (ASIM) provides insights into their role in Earth’s atmosphere and climate, including mechanisms behind the creation of lightning. Understanding how thunderstorms and lightning disturb the upper atmosphere could improve atmospheric models along with climate and weather predictions. These high-altitude discharges also affect aircraft and spacecraft safety.

      Researchers conclude that the space station’s ECOSTRESS instrument yields highly accurate sea surface temperature data. Given the instrument’s global coverage and high spatial resolution, these data have potential use in studies of biological and physical oceanography to evaluate regional and local effects of climate change.

      ECOSTRESS resolves oceanographic features not detectable in imagery from NOAA’s Visible Infrared Imaging Radiometer Suite satellite, and has open-ocean coverage, unlike Landsat. Satellites are a fundamental tool to measure sea surface temperatures, which are rising across all oceans due to atmospheric warming induced by climate change.

      Researchers report detailed observations and analysis of emissions from an exceptionally bright gamma ray burst (GRB), 210619B, detected by the station’s ASIM and other satellite and ground-based instruments. These observations could be useful in determining various properties of GRBs and how they change during different phases.

      Believed to be generated by the collapse of massive stars, GRBs are the brightest, most explosive transient electromagnetic events in the universe. ASIM can observe thunderstorm discharges difficult to observe from the ground. It has a mode where a detected event triggers observation and onboard storage of data.

      Sols 4454-4457: Getting Ready to Fill the Long Weekend with Science
      NASA’s Mars rover Curiosity acquired this image, which includes the pyramid-shaped rock at left in the photo, the science target dubbed “Pyramid Lake,” using its Left Navigation Camera. The rover acquired the image on sol 4452, or Martian day 4,452 of the Mars Science Laboratory mission, on Feb. 13, 2025, at 14:22:06 UTC. NASA/JPL-Caltech Earth planning date: Friday, Feb. 14, 2025
      Curiosity is continuing to make progress along the strategic route, traversing laterally across the sulfate (salt) bearing unit toward the boxwork structures. The team celebrated the completion of another successful drive when we received the downlink this morning, and then we immediately got to work thinking about what’s next. There is a holiday in the United States on Monday, so instead of the typical three-sol weekend plan, we actually planned four sols, which will set us up to return to planning next Tuesday.
      The first sol of the plan focuses on remote sensing, and we’ll be taking several small Mastcam mosaics of features around the rover. One of my favorite targets the team picked is a delightfully pointy rock visible toward the left of the Navcam image shown above. The color images we’ll take with Mastcam will give us more information about the textures of this rock and potentially provide insight into the geologic forces that transformed it into this comical shape. The team chose what I think is a very appropriate name for this Martian pyramid-shaped target — “Pyramid Lake.” The terrestrial inspiration behind this name is a human-made reservoir (lake) near Los Angeles with a big (also human-made) pyramidal hill in it.
      On the second sol of the plan, we’ll use the instruments on Curiosity’s arm to collect data of rock targets at our feet, including “Strawberry Peak,” a bumpy piece of bedrock, “Lake Arrowhead,” a smooth piece of bedrock, and “Skyline Trail,” a dark float rock. ChemCam will also collect chemical data of Skyline Trail, “Big Tujunga” — which is similar to Strawberry Peak — and “Momyer.” We’ll also take the first part of a 360-degree color mosaic with Mastcam!
      In the third sol of the plan, we’ll complete the 360-degree mosaic and continue driving to the southwest along our strategic route. The fourth sol is pretty quiet, with some atmospheric observations and a ChemCam AEGIS. Atmospheric observations are additionally sprinkled throughout other sols of the plan. This time of year we are particularly interested in studying the clouds above Gale crater!
      I’m looking forward to the nice long weekend, and returning on Tuesday morning to see everything Curiosity accomplished.
