      NASA to Launch Three Rockets from Alaska in Single Aurora Experiment
      Three NASA-funded rockets are set to launch from Poker Flat Research Range in Fairbanks, Alaska, in an experiment that seeks to reveal how auroral substorms affect the behavior and composition of Earth’s far upper atmosphere. 
      The experiment’s outcome could upend a long-held theory about the aurora’s interaction with the thermosphere. It may also improve space weather forecasting, critical as the world becomes increasingly reliant on satellite-based devices such as GPS units in everyday life.
      Colorful ribbons of aurora sway with geomagnetic activity above the launch pads of Poker Flat Research Range. NASA/Rachel Lense The University of Alaska Fairbanks (UAF) Geophysical Institute owns Poker Flat, located 20 miles north of Fairbanks, and operates it under a contract with NASA’s Wallops Flight Facility in Virginia, which is part of NASA’s Goddard Space Flight Center in Greenbelt, Maryland.
      The experiment, titled Auroral Waves Excited by Substorm Onset Magnetic Events, or AWESOME, features one four-stage rocket and two two-stage rockets all launching in an approximately three-hour period.
      Colorful vapor tracers from the largest of the three rockets should be visible across much of northern Alaska. The launch window is March 24 through April 6.
      The mission, led by Mark Conde, a space physics professor at UAF, involves about a dozen UAF graduate student researchers at several ground monitoring sites in Alaska at Utqiagvik, Kaktovik, Toolik Lake, Eagle, and Venetie, as well as Poker Flat.  NASA delivers, assembles, tests, and launches the rockets.
      “Our experiment asks the question, when the aurora goes berserk and dumps a bunch of heat in the atmosphere, how much of that heat is spent transporting the air upward in a continuous convective plume and how much of that heat results in not only vertical but also horizontal oscillations in the atmosphere?” Conde said.
      Confirming which process is dominant will reveal the breadth of the mixing and the related changes in the thin air’s characteristics.
      “Change in composition of the atmosphere has consequences,” Conde said. “And we need to know the extent of those consequences.”
      Most of the thermosphere, which reaches from about 50 to 350 miles above the surface, is what scientists call “convectively stable.” That means minimal vertical motion of air, because the warmer air is already at the top, due to absorption of solar radiation.
      A technician with NASA’s Wallops Flight Facility sounding rocket office works on one of the payload sections of the rocket that will launch for the AWESOME campaign. NASA/Lee Wingfield When auroral substorms inject energy and momentum into the middle and lower thermosphere (roughly 60 to 125 miles up), it upsets that stability. That leads to one prevailing theory — that the substorms’ heat is what causes the vertical-motion churn of the thermosphere.
      Conde believes instead that acoustic-buoyancy waves are the dominant mixing force and that vertical convection has a much lesser role. Because acoustic-buoyancy waves travel vertically and horizontally from where the aurora hits, the aurora-caused atmospheric changes could be occurring over a much broader area than currently believed.
      Better prediction of impacts from those changes is the AWESOME mission’s practical goal.
      “I believe our experiment will lead to a simpler and more accurate method of space weather prediction,” Conde said.
      Two two-stage, 42-foot Terrier-Improved Malemute rockets are planned to respectively launch about 15 minutes and an hour after an auroral substorm begins. A four-stage, 70-foot Black Brant XII rocket is planned to launch about five minutes after the second rocket. 
      The first two rockets will release tracers at altitudes of 50 and 110 miles to detect wind movement and wave oscillations. The third rocket will release tracers at five altitudes from 68 to 155 miles.
      Pink, blue, and white vapor traces should be visible from the third rocket for 10 to 20 minutes. Launches must occur in the dawn hours, with sunlight hitting the upper altitudes to activate the vapor tracers from the first rocket but darkness at the surface so ground cameras can photograph the tracers’ response to air movement.

      Preparations for Next Moonwalk Simulations Underway (and Underwater)
      NASA / Lillian Gipson NASA has selected three university teams to help solve 21st century aviation challenges that could transform the skies above our communities. 
      As part of NASA’s University Leadership Initiative (ULI), both graduate and undergraduate students on faculty-led university teams will contribute directly to real-world flight research while gaining hands-on experience working with partners from other universities and industry. 
      By combining faculty expertise, student innovation, and industry experience, these three teams will advance NASA’s vision for the future of 21st century aviation.
      koushik datta
      NASA Project Manager
      This is NASA’s eighth round of annual ULI awards. Research topics include: 
      New aviation systems for safer, more efficient flight operations   Improved communications frequency usage for more effective and reliable information transfer  Autonomous flight capabilities that could advance research in areas such as NASA’s Advanced Air Mobility mission  “By combining faculty expertise, student innovation, and industry experience, these three teams will advance NASA’s vision for the future of 21st century aviation,” said Koushik Datta, NASA University Innovation project manager at the Agency’s Ames Research Center in California. 
      This eighth round of annual ULI selections would lead to awards totaling up to $20.7 million for the three teams during the next three years. For each team, the proposing university will serve as lead. The new ULI selections are: 
      Florida Institute of Technology, Melbourne, Florida

      On 8 January 2025, the ESA/JAXA BepiColombo mission flew past Mercury for the sixth time, successfully completing the final ‘gravity assist manoeuvre’ needed to steer it into orbit around the planet in late 2026. The spacecraft flew just a few hundred kilometres above the planet's north pole. Close-up images expose possibly icy craters whose floors are in permanent shadow, and the vast sunlit northern plains.

      Video: 00:01:14 At the start of this new year, we look back at close-up pictures and solar flare data recorded by the ESA-led Solar Orbiter mission over the last three years. See and hear for yourself how the number of flares and their intensity increase, a clear sign of the Sun approaching the peak of the 11-year solar cycle. 
      This video combines ultraviolet images of the Sun's outer atmosphere (the corona, yellow) taken by Solar Orbiter's Extreme Ultraviolet Imager (EUI) instrument, with the size and locations of solar flares (blue circles) as recorded by the Spectrometer/Telescope for Imaging X-rays (STIX) instrument. The accompanying audio is a sonification based on the detected flares and the spacecraft's distance to the Sun.   
      Solar Orbiter moves on an elliptical path around the Sun, making a close approach to our star every six months. We can see this in the video from the spacecraft's perspective, with the Sun moving closer and farther over the course of each year. In the sonification, this is represented by the low background humming that loudens as the Sun gets closer and becomes quieter as it moves further away. (There are some abrupt shifts in distance visible in the video, as it skips over dates where one or both instruments were inactive or collecting a different type of data.)  
      The blue circles represent solar flares: bursts of high-energy radiation of which STIX detects the X-rays. Flares are sent out by the Sun when energy stored in 'twisted' magnetic fields (usually above sunspots) is suddenly released. The size of each circle indicates how strong the flare is, with stronger flares sending out more X-rays. We can hear the flares in the metallic clinks in the sonification, where the sharpness of the sound corresponds to how energetic the solar flare is. 
      Many thanks to Klaus Nielsen (DTU Space / Maple Pools) for making the sonification in this video. If you would like to hear more sonifications and music by this artist, please visit: https://linktr.ee/maplepools
