Background: Importance and complexity of the ionosphere The problem is that the electron density varies greatly -- depending on the longitude and latitude above the Earth, the time of day and year, and solar activity. This makes it difficult to reconstruct…
Scientists from NASA and three universities have presented new discoveries about the way heat and energy move and manifest in the ionosphere, a region of Earth's atmosphere that reacts to changes from both space above and Earth below. Changes in…

EDITOR’S NOTE: Part 5 of a series. Over the past several weeks, we have taken quite a journey through Earth’s atmosphere. We started right here at the surface in the troposphere, where our weather develops. We climbed through the stratosphere, home…
University of Chicago fourth-year physics major Larry Li cruised through the New Mexican desert night in a tiny hatchback stuffed with toolboxes, a 3D printer and a payload that would soon float to the sky. “I hit Albuquerque and there were…
University of Colorado Boulder Bob MarshallAssociate Professor, Smead AerospaceFriday, Oct 16 | 10:40 A.M | AERO 111Abstract: My research group has taken three CubeSat missions from proposal to orbit over the past six years Initiated in the uncertain months of early 2020, AEPEX (NASA Heliophysics), CANVAS…
The European Space Agency’s (ESA) Sawa mission is its second space weather nanosatellite mission. Sawa will primarily watch the thermosphere in situ from Earth orbit, observing how space weather causes the atmospheric layer to warm up and expand, pushing satellites…
The New Moon arrives Saturday, October 10, giving stargazers darker nights through the weekend. There’s also a chance of elevated aurora activity late Friday night, though NOAA’s forecast does not necessarily promise a display. NOAA’s latest three-day forecast, issued Friday evening,…
Flying through a magnetic switchback in the Sun’s magnetic field, the European Space Agency’s Solar Orbiter has collected important new data that could improve our understanding of dangerous space weather. In a new study published in Nature Astronomy, researchers analyzed…
