Climate & Space Professor Michael Liemohn has written an article about the value of archiving data for the latest issue of the American Geophysical Union's Eos magazine. The article examines new findings derived from archived Voyager mission Jupiter flyby data collected back in 1979, and the subsequent published studies. Several of those initial studies were authored by Fran Bagenal, now a professor at the University of Colorado's Laboratory for Atmospheric and Space Physics (LASP) in Boulder. 
From the article:
"We are approaching the 40-year anniversary of the two Voyager spacecraft making their 1979 flybys of the planet Jupiter. Jupiter’s magnetosphere is big. The satellites were moving fast, and each one only spent a few days passing through the magnetic bubble around this planet so two flybys does not seem like much of an opportunity to gather data. But the plasma science instruments on the spacecraft were high quality sensors that led to numerous papers on the magnetospheric structure, dynamics, composition, and dominant physical processes.

"Long after the Voyager observations the Galileo spacecraft orbited Jupiter for 8 years in the 1990s and 2000s, providing a rich set of magnetospheric measurements for nearly a solar cycle.

"The Voyager flybys, however, offer comparative and complementary measurements from a different solar cycle and are still proving themselves to be useful. 

Professor Fran Bagenal will give a presentation titled, "NASA's Juno Mission to Jupiter: What’s Inside the Giant Planet?" as part of the CLaSP Seminar Series on Thursday, September 21st, 3:30 pm in the SRB Auditorium. Please join us!
