Jupiter
Jupiter is the fifth planet from the Sun and the largest in the Solar System. It is a gas giant with a mass more than two and a half times that of all the other planets in the Solar System combined, but slightly less than one-thousandth t ...

Overview
If developed in the future, the ''FIRE'' spacecraft would use threegravity assist
In orbital mechanics and aerospace engineering, a gravitational slingshot, gravity assist maneuver, or swing-by is the use of the relative movement (e.g. orbit around the Sun) and gravity of a planet or other astronomical object to alter the p ...
s to reach Jupiter six years later. The spacecraft would orbit Jupiter and perform 10 flybys of Io, some as low as from its surface. The ten flybys would be completed in approximately four months.
As a New Frontiers class mission, the cost cap would be $991 million (FY2012) with a $927 million base cap with a $64 million launch vehicle cost credit.

Power
Electric power to the spacecraft and its scientific payload would be generated by three Advanced Stirling Radioisotope Generators (ASRG). ASRG is aradioisotope
A radionuclide (radioactive nuclide, radioisotope or radioactive isotope) is a nuclide that has excess nuclear energy, making it unstable. This excess energy can be used in one of three ways: emitted from the nucleus as gamma radiation; transferr ...
