The crucial role of HST during the NASA Juno mission: a 'Juno initiative'

Autor: Grodent, Denis, Bonfond, Bertrand, Gérard, Jean-Claude, Gladstone, G. Randall, Nichols, Jonathan D., Clarke, John T., Bagenal, Fran, Adriani, Alberto

In 2016, the NASA Juno spacecraft will initiate its one-year mission around Jupiter and become the first probe to explore the polar regions of Jupiter. The HST UV instruments (STIS and ACS) can greatly contribute to the success of the Juno mission by
