The cancellation of the Rosetta launch to Comet Wirtanen in 2003 left the spacecraft fully fuelled but with no target. Whilst a new mission scenario was devised it was necessary to make the spacecraft as safe as possible to carry out essential work on the payload and subsystems. It was required to offload all of the MonoMethyl Hydrazine (MMH) fuel to minimize the explosive potential of the spacecraft. In addition a reduction of the MMH vapors remaining in the spacecraft tanks to a maximum of 1200 ppm was required to allow reloading of the MMH at a later date. This paper details the preparation and execution of the Rosetta MMH offload and tank drying campaign, which ultimately was extremely successful. The decision to leave the MON oxidiser on-board is discussed as is the oxidiser offloading plan, specifically in the context of avoiding any stress corrosion effects. Finally it presents the lessons learned from the campaign and suggests improvements for future spacecraft operations.
