USA planerar en obemannad mnexpedition 2010. Tv robotar ska landsttas fr att samla stenprover och sedan tervnda till Jorden.

Enligt planen ska robotarna utforska mnens strsta och ldsta krater, Aitken-bckenet vid sydpolen, avsljade forskaren Carle Pieters p en konferens i Indien med ver 200 deltagare frn 16 lnder.

Pieters r engagerad i USA:s rymdprogram och knuten till den geologiska institutionen p Brown University.

Syftet blir att studera fr hur lnge sedan bckenet blev till och att ta reda p hur sdana bcken bildas.

Materialet ska sedan forslas till Jorden fr analys.

Varje robot kommer att samla ett kilo sten och fragment som ska ge oss insikt om bckenets geologiska historia, berttade hon fr deltagarna p den internationella konferensen.

SSTL har meddelat att UO-22 r i s dligt skick att den snart att ha ntt sitt slut. Satelliiten har varit aktiv sedan 1991. Se nedanstende:

AMSAT-UK have been informed by SSTL that UO-22 is not in good shape, and its looks as though its useful life may be over. The SSTL Ground Station control centre at the University of Surrey have attempted several times in recent weeks to reactivate the satellite.

After one attempt it did come back to life, but only briefly. Other attempts have failed completely. As time permitts, the Control Station may make further attempts at reactivation, but it seems unlikely that they will be completely successful.

The cause if the satellite s demise is unknown, but may be related to the batteries which have been in space for more than 10 years, or to the fact that the satellite is very hot due to the orbit preccessing such that it is generall in full sunlight. The elevated temparature was causing problems with the receivers, as well as the battery.
UO-22 was laaunched in July 1991 from Kourou, French Guiana, and served for many years as the store and forward satellite for the Amateur Radio Packet Radio world wide SatGate service, which linked packet radio networks in many countries.
