Chepuri, Fasano Featured in Dare to Discover Campaign

Friday, January 26, 2024
PhD students Sanjay Chepuri and Cecilia Fasano are among 80 University of Iowa undergraduates, graduate students, and postdoctoral researchers and scholars in the Dare to Discover campaign, sponsored by the Office of the Vice President for Research. The ninth installation of the campaign showcases UI researchers, scholars, and creators on banners hung in downtown Iowa City from January to March 2024.

Payne Designs Big-Ticket Mission at NASA Design School

Graduate student Jacob Payne went to school—but not just any school. Payne earlier this year attended NASA’s Astrophysics Mission Design School, the first ever in astrophysics offered by NASA that teaches grad students how to write proposals for grand-idea, big-budget missions.

Kurth Discusses Voyager Mission

Friday, December 22, 2023
Bill Kurth was interviewed on the Dec. 21 BBC Science in Action program about the iconic Voyager 1 craft, which has started sending back nonsense data.   Kurth, who has worked on Voyager since its launch in 1977, reveals his personal and scientific connection to the mission.

Kurth Describes How Sounds from Space Revealed Lightning on Jupiter, Saturn

In this AGU Eos article "The 21st Century’s “Music of the Spheres”about how data sonification is used to analyze and appreciate cosmic objects, Research Scientist/Engineer Bill Kurth describes how Voyager 1 recorded signals known as whistlers to detect lightning in the roiling clouds of Jupiter. The Cassini spacecraft, which orbited Saturn for 13 years, similarly revealed lightning in the ringed planet’s atmosphere.

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.
