Laplace was selected as a Large-class candidate mission in the Cosmic Vision 2015-25 programme and underwent an assessment study (phase 0/A, 2008-2010) under the assumption of an international cooperation including ESA and NASA. Following the announcement of the US Planetary Science Decadal Survey, and the evolution of the NASA budget, it was decided in April 2011 to revisit the 3 mission candidates for targeting "Europe-alone" missions. Consequently, the Study Science Team has investigated different options to recover parts of the original science goals of the Laplace mission. The new mission scenario will be presented.
