Status of the mission
The ESA internal assessment phase, or phase 0, for all candidate missions began in November 2007. The CDF study, part of the phase 0 process, for TandEM ran from June 2008 to July 2008.
At the beginning of 2009 a down-selection will take place between the two mission studies TandEM (Saturn) and Laplace (Jupiter). This will be jointly done by ESA and NASA. Only the selected mission will be subsequently studied by industry.
In the first half of 2009 the Invitation to Tender is planned to be issued to Industry, resulting in parallel industrial assessment studies that will run for approximately 18 months. These studies are expected to be completed by the end of 2010.
