Halekas, Jaynes Discuss Solar Wind Disappearances near Earth and Mars

In this article in the Washington Post, Prof. Jasper Halekas comments on the MAVEN spacecraft's observation in December 2022 of a sudden lull in the solar wind around Mars, with the density of the solar wind around Mars dropping by a factor of 100. Later in the article, Prof. Allison Jaynes discusses how low-density solar events in the Earth's atmosphere can disrupt communications and cause an unusually intense polar rain — a type of aurora.

APS News: The Scientist Who Launches Rockets at the Northern Lights

At an APS meeting in Denver, astrophysicist Allison Jaynes discussed her work on auroras and the strange plasma physics that shapes them. Jaynes, this year’s recipient of APS’s Katherine E. Weimer Award in plasma physics, discussed her research at this year’s meeting of the APS Division of Plasma Physics in Denver, Colorado.

MAVEN Observes the Disappearing Solar Wind

In December 2022, NASA's MAVEN (Mars Atmosphere and Volatile EvolutioN) mission observed the dramatic and unexpected "disappearance" of a stream of charged particles constantly emanating off the Sun, known as the solar wind. This was caused by a special type of solar event that was so powerful, it created a void in its wake as it traveled through the solar system.

Wang, Jun

Jun Wang contributed to one of Time Magazine’s 'best inventions' of 2023

Prof. Jun Wang, who holds a secondary appointment in the Department of Physics and Astronomy, is Iowa’s lead investigator on Tropospheric Emissions: Monitoring Pollution or TEMPO. The space instrument is expected to help scientists understand the sources of pollution by revolutionizing how real-time air quality data is collected.

Jaynes Receives Grant for LAMPsat Instrumentation

Tuesday, November 28, 2023
Associate Professor Allison Jaynes has received a $44,018 award from Johns Hopkins University Applied Physics Laboratory to support the development of a University of Iowa energetic particle detector instrument for a CubeSat concept mission to study energetic precipitation into the atmosphere from space, particularly during times of a widespread, common type of aurora called pulsating aurora.
