The Juno mission to Jupiter is scheduled to launch this coming summer. Aviation Week and Space Technology just published two articles on the mission, one focused on design and implementation and the other on the science. Normally, AWST requires a subscription to read, but both articles are posted on public websites.
The science article is posted on AWST's website. The other, longer article, appears to be available on the Zinio website, which provides an electronic subscription service to magazines and other media. I subscribe to AWST through Zinio, so it is possible that the link to this article may not work for those without the subscription.
