LUNAM 2000 is a small mission dedicated to the coronagraphic imagingin the Na yellow doublet and to UV spectroscopy in the range2800–3400 Å of the lunar atmosphere. These studies are possible only from Space. The scientific return of LUNAM 2000 has a wider appeal for the studyof transient atmospheres of other celestial bodies, in particular ofMercury. The mission is in low Earth-orbit (about 350 km); asun-synchronous or other orbits are under investigation. The payload has very small weight, dimensions and power requests, and is essentially made withoff-the-shelf components. It can be built and launched in less than 3years from the approval. This time frame nicely overlaps that of theEuropean technological Mission SMART 1 and can greatly add to itsscientific return. Furthermore, LUNAM 2000 can give very importantinformation to define a mission to Mercury such as Bepi Colombo. |
