NASA has selected three proposals for concept studies of missions to investigate the complex system of space weather that surrounds our planet and how it’s connected to Earth’s atmosphere.

The three concepts propose how to enact the DYNAMIC (Dynamical Neutral Atmosphere-Ionosphere Coupling) mission, which was recommended by the 2013 Decadal Survey for Solar and Space Physics. The DYNAMIC mission is designed to study how changes in Earth’s lower atmosphere influence our planet’s upper atmosphere, where space weather like auroras and satellite disruptions are manifested. This knowledge will benefit humanity by helping us understand how space weather can interfere with crucial technology like navigation systems and satellites.

“Earth and space are an interconnected system that reaches from the heart of our solar system, the Sun, to the lowest reaches of the atmosphere where we live and extends to the edge of our heliosphere – the boundary of interstellar space,” said Nicola Fox, associate administrator, Science Mission Directorate at NASA Headquarters in Washington. “While space weather can spark the beautiful auroras across our skies, it also has the potential to cause disruptions for us here on Earth and can be dangerous for our spacecraft and astronauts in space. The DYNAMIC mission will expand our understanding of how Earth itself shapes space weather events that influence our home planet.”

The DYNAMIC mission is designed to make measurements within Earth’s upper atmosphere between about 50-125 miles (80-200 kilometers) in altitude. With multiple spacecraft, DYNAMIC’s simultaneous observations from different locations can give scientists a more complete picture of how waves propagate upwards through this part of the atmosphere.

NASA’s fiscal year 2023 appropriation directed NASA to initiate this first phase of study. As the first step of a two-step selection process, each proposal will receive $2 million for a concept study. NASA solicited missions with a cost cap of $250 million, which does not include the launch. The studies will last nine months.

The selected concept teams are:

  • University of Colorado, Boulder, led by principal investigator Tomoko Matsuo

Key partners include Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland; NASA’s Jet Propulsion Laboratory in Southern California; and Massachusetts Institute of Technology’s Haystack Observatory in Westford, Massachusetts.

  • University of Colorado, Boulder, led by principal investigator Aimee Merkel

Key partners include BAE Systems in Westminster, Colorado, and the Naval Research Laboratory in Washington.

  • Virginia Polytechnic Institute and State University, led by principal investigator Scott Bailey

Key partners include Southwest Research Institute in San Antonio, Texas, Space Dynamics Laboratory in Logan, Utah, Global Atmospheric Technologies and Sciences in Newport News, Virginia, and Computational Physics, Inc. in Boulder, Colorado.

      NASA’s Human Landing System (HLS) will transport the next astronauts that land on the Moon, including the first woman and first person of color, beginning with Artemis III. For safety and mission success, the landers and other equipment in development for NASA’s Artemis campaign must work reliably in the harshest of environments.
      The Hub for Innovative Thermal Technology Maturation and Prototyping (HI-TTeMP) lab at NASA’s Marshall Space Flight Center in Huntsville, Alabama, provides engineers with thermal analysis of materials that may be a prototype or in an early developmental stage using a vacuum chamber, back left, and a conduction chamber, right. NASA/Ken Hall Engineers at NASA’s Marshall Space Flight Center in Huntsville, Alabama, are currently testing how well prototype insulation for SpaceX’s Starship HLS will insulate interior environments, including propellant storage tanks and the crew cabin. Starship HLS will land astronauts on the lunar surface during Artemis III and Artemis IV.
      Marshall’s Hub for Innovative Thermal Technology Maturation and Prototyping (HI-TTeMP) laboratory provides the resources and tools for an early, quick-check evaluation of insulation materials destined for Artemis deep space missions.
      “Marshall’s HI-TTeMP lab gives us a key testing capability to help determine how well the current materials being designed for vehicles like SpaceX’s orbital propellant storage depot and Starship HLS, will insulate the liquid oxygen and methane propellants,” said HLS chief engineer Rene Ortega. “By using this lab and the expertise provided by the thermal engineers at Marshall, we are gaining valuable feedback earlier in the design and development process that will provide additional information before qualifying hardware for deep space missions.”
      A peek inside the conductive test chamber at NASA Marshall’s HI-TTeMP lab where thermal engineers design, set up, execute, and analyze materials destined for deep space to better understand how they will perform in the cold near-vacuum of space. NASA/Ken Hall On the Moon, spaceflight hardware like Starship HLS will face extreme temperatures. On the Moon’s south pole during lunar night, temperatures can plummet to -370 degrees Fahrenheit (-223 degrees Celsius). Elsewhere in deep space temperatures can range from roughly 250 degrees Fahrenheit (120 degrees Celsius) in direct sunlight to just above absolute zero in the shadows.
      There are two primary means of managing thermal conditions: active and passive. Passive thermal controls include materials such as insulation, white paint, thermal blankets, and reflective metals. Engineers can also design operational controls, such as pointing thermally sensitive areas of a spacecraft away from direct sunlight, to help manage extreme thermal conditions. Active thermal control measures that could be used include radiators or cryogenic coolers.
      Engineers use two vacuum test chambers in the lab to simulate the heat transfer effects of the deep space environment and to evaluate the thermal properties of the materials. One chamber is used to understand radiant heat, which directly warms an object in its path, such as when heat from the Sun shines on it. The other test chamber evaluates conduction by isolating and measuring its heat transfer paths.
      NASA engineers working in the HI-TTeMP lab not only design, set up, and run tests, they also provide insight and expertise in thermal engineering to assist NASA’s industry partners, such as SpaceX and other organizations, in validating concepts and models, or suggesting changes to designs. The lab is able to rapidly test and evaluate design updates or iterations.
      NASA’s HLS Program, managed by NASA Marshall, is charged with safely landing astronauts on the Moon as part of Artemis. NASA has awarded contracts to SpaceX for landing services for Artemis III and IV and to Blue Origin for Artemis V. Both landing services providers plan to transfer super-cold propellant in space to send landers to the Moon with full tanks.
      With Artemis, NASA will explore more of the Moon than ever before, learn how to live and work away from home, and prepare for future human exploration of Mars. NASA’s SLS (Space Launch System) rocket, exploration ground systems, and Orion spacecraft, along with the HLS, next-generation spacesuits, Gateway lunar space station, and future rovers are NASA’s foundation for deep space exploration.

      5 Surprising NASA Heliophysics Discoveries Not Related to the Sun
      With NASA’s fleet of heliophysics spacecraft, scientists monitor our Sun and investigate its influences throughout the solar system. However, the fleet’s constant watch and often-unique perspectives sometimes create opportunities to make discoveries that no one expected, helping us to solve mysteries about of the solar system and beyond.
      Here are five examples of breakthroughs made by NASA heliophysics missions in other fields of science.
      This graphic shows missions in NASA’s Heliophysics Division fleet as of July 2024. NASA Thousands and Thousands of Comets
      The SOHO mission — short for Solar and Heliospheric Observatory, which is a joint mission between ESA (European Space Agency) and NASA — has a coronagraph that blocks out the Sun in order to see the Sun’s faint outer atmosphere, or corona. 
      It turns out SOHO’s coronagraph also makes it easy to spot sungrazing comets, those that pass so close to the Sun that other observatories can’t see them against the brightness of our star.
      Before SOHO was launched in December 1995, fewer than 20 sungrazing comets were known. Since then, SOHO has discovered more than 5,000. 
      The vast number of comets discovered using SOHO has allowed scientists to learn more about sungrazing comets and identify comet families, descended from ancestor comets that broke up long ago.

      Two sungrazing comets fly close to the Sun in these images captured by ESA/NASA’s SOHO (Solar and Heliospheric Observatory). They were the 3,999th and 4,000th comets discovered in SOHO images. ESA/NASA/SOHO/Karl Battams Dimming of a Supergiant
      In late 2019, the supergiant star Betelgeuse began dimming unexpectedly. Telescopes all over the world — ​​​​and around it — tracked these changes until a few months later when Betelgeuse appeared too close to the Sun to observe. That’s when NASA’s STEREO (Sun-watching Solar Terrestrial Relations Observatory (STEREO) came to the rescue. 
      For several weeks in the middle of 2020, STEREO was the only observatory able to see Betelgeuse. At the time, the STEREO-A spacecraft was trailing behind Earth, at a vantage point where Betelgeuse was still far enough away from the Sun to be seen. This allowed astronomers to keep tabs on the star while it was out of view from Earth.  
      STEREO’s observations revealed another unexpected dimming between June and August of 2020, when ground-based telescopes couldn’t view the star.
      Astronomers later concluded that these dimming episodes were caused by an ejection of mass from Betelgeuse — like a coronal mass ejection from our Sun but with about 400 times more mass — which obscured part of the star’s bright surface.

The inset figure shows measurements of Betelgeuse’s brightness taken by different observatories from late 2018 to late 2020. STEREO’s observations, marked in red, revealed an unexpected dimming in mid-2020 when Betelgeuse appeared too close to the Sun for other observatories to view it. NASA/STEREO/HI (background); Dupree et al. (inset) The Glowing Surface of Venus
      NASA’s Parker Solar Probe studies the Sun’s corona up close — by flying through it. To dive into the Sun’s outer atmosphere, the spacecraft has flown past Venus several times, using the planet’s gravity to fling itself closer and closer to the Sun.
      On July 11, 2020, during Parker’s third Venus flyby, scientists used Parker’s wide-field imager, called WISPR, to try to measure the speed of the clouds that obscure Venus’ surface. Surprisingly, WISPR not only observed the clouds, it also saw through them to the surface below.
      The images from that flyby and the next (in 2021) revealed a faint glow from Venus’ hot surface in near-infrared light and long wavelengths of red (visible) light that maps distinctive features like mountainous regions, plains, and plateaus.
      Scientists aimed WISPR at Venus again on Nov. 6, 2024, during Parker’s seventh flyby, observing a different part of the planet than previous flybys. With these images, they’re hoping to learn more about Venus’ surface geology, mineralogy, and evolution.

      As Parker Solar Probe flew by Venus on its fourth flyby, it captured these images, strung into a video, showing bright and dark features on the nightside surface of the planet. NASA/APL/NRL The Brightest Gamma-Ray Burst
      You’ve heard of the GOAT. But have you heard of the BOAT?
      It stands for the “brightest of all time”, a gamma-ray burst discovered on Oct. 9, 2022.  
      A gamma-ray burst is a brief but intense eruption of gamma rays in space, lasting from seconds to hours.
      This one, named GRB 221009A, glowed brilliantly for about 10 minutes in the constellation Sagitta before slowly fading.
      The burst was detected by dozens of spacecraft, including NASA’s Wind, which studies the perpetual flow of particles from the Sun, called the solar wind, just before it reaches Earth.
      Wind and NASA’s Fermi Gamma-Ray Space Telescope measured the brightness of GRB 221009A, showing that it was 70 times brighter than any other gamma-ray burst ever recorded by humans — solidifying its status as the BOAT.

      Learn More

      Astronomers think GRB 221009A represents the birth of a new black hole formed within the heart of a collapsing star. In this artist’s concept, the black hole drives powerful jets of particles traveling near the speed of light. The jets emit X-rays and gamma rays as they stream into space. NASA/Swift/Cruz deWilde A Volcano Blasts Its Way to Space
      NASA’s ICON (Ionospheric Connection Explorer) launched in 2019 to study how Earth’s weather interacts with weather from space. When the underwater Hunga Tonga-Hunga Ha‘apai volcano erupted on Jan. 15, 2022, ICON helped show that the volcano produced more than ash and tsunami waves — its effects reached the edge of space.
      In the hours after the eruption, ICON detected hurricane-speed winds in the ionosphere — Earth’s electrified upper atmospheric layer at the edge of space. ICON clocked the wind speeds at up to 450 miles per hour, making them the strongest winds the mission had ever measured below 120 miles altitude.
      The ESA Swarm mission revealed that these extreme winds altered an electric current in the ionosphere called the equatorial electrojet. After the eruption, the equatorial electrojet surged to five times its normal peak power and dramatically flipped direction.
      Scientists were surprised that a volcano could affect the electrojet so severely — something they’d only seen during a strong geomagnetic storm caused by an eruption from the Sun.

      The Hunga Tonga-Hunga Ha’apai eruption on Jan. 15, 2022, caused many effects, some illustrated here, that were felt around the world and even into space. Some of those effects, like extreme winds and unusual electric currents were picked up by NASA’s ICON (Ionospheric Connection Explorer) mission and ESA’s (the European Space Agency) Swarm.
