The Horizon 2000 Plus space science program remains in the formative stage, but two proposals, including a Mercury orbiter, already have strong internal support. Launches areanticipated in the 2006-2016 time-frame (References 117-119). Meanwhile, a separate effort is underway by some ESA members to adopt a more aggressive lunar exploration program which would include lunar landers and automated lunar scientific stations (References 120-122).
