The observation and study of the Universe requires coordinated, if

possible, contemporary observations in different windows of the Electromagnetic Spectrum

3 The lack of atmosphere renders the Moon surface an appealing location

The lack of atmosphere renders the Moon surface an appealing location

for X and Gamma-ray telescopes.

However, to be competitive with the space instruments already in operations, we need large X and gamma-ray telescopes that are far too big to be considered for space operations.

The four Telescopes we have selected to explore the Universe in the

energy band few keV, many GeV, are transit instruments with no specific pointing requirements, (the sources will cross the instruments field of view at 0.5/h at the Equator).

Placing the instruments on the Moon equatorial region would allow an even coverage of the sky and ease the communications.

The four telescopes are very big, they cannot be sent to the Moon in just one flight unless a system like the one in the NASA ESAS study is available .

28 CONCLUSIONS

CONCLUSIONS

X and gamma-ray astronomy could blossom on the Moon surface. However, the flight opportunity of 2011 and 2012 is not suitable for the ambitious goals we have set for the Lunar A.O.

29 CONCLUSIONS

CONCLUSIONS

In view of the space competitors, it makes no sense to propose a small payload for the first flight opportunity. A Payload in the 80 kg. range can accommodate only a test instrument or a technological demonstrator. Such a small instrument could provide useful information for the detailed design of the future BIG TELESCOPES.

30 CONCLUSIONS

CONCLUSIONS

The 2012 opportunity could be used to fly to the Moon a small instrument to get the best possible information on one of the critical lunar parameter like the Dust, the Micrometeorites, the Temperature excursions of the Telescopes components, the total Radiation. All those inputs will be needed when the Big Telescope time will arrive.
