Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Maria Zuber weMassachusetts Institute of Technology ndiye muongorori mukuru weGRAIL. Jet Propulsion Laboratory yeNASA ndiyo iri kutarisira basa racho. Musi waAugust 5, 2011, purogiramu yacho yakanga yabhadhara US$496 miriyoni. Pakutangwa kwechikepe chomuchadenga chakatumidzwa mazita okuti GRAIL A neGRAIL B uye makwikwi akavhurwa kuvana vechikoro kuti vasarudze mazita. Makirasi anoda kusvika 900 anobva mumatunhu 45, Puerto Rico neDistrict of Columbia, akapinda mumakwikwi aya. Mazita akahwina, Ebb naFlow, akakurudzirwa nevadzidzi vegiredhi rechina paEmily Dickinson Elementary School muBozeman, Montana. Chikepe chemuchadenga chimwe nechimwe chakatumira uye chakagamuchira telemetry kubva kune zvimwe zvikepe zvemuchadenga uye zvivakwa zvepasi. Kupfurikidza nokuyera chinjo iri kure pakati pemidziyo miviri yomuchadenga, simba rinokweva uye chimiro chechimiro chomwedzi zvakawanwa. Zvikepe zviviri zvomuchadenga zvaikwanisa kuona kuchinja kuduku-duku kuri pakati peimwe neimwe. Kuchinja kuri kure kwakanga kuri kuduku semicron imwe kwaigona kuonekwa uye kuyerwa. Munda wokukweva weMwedzi wakaiswa pamepu zvakadzama zvisati zvamboitika.  Mubvunzo: Ipurogiramu ipi inotarisirwa neLabhoritari?
