NASA wants to give the Moon a moon

Focus-Science and Technology - - Discoveries -

IT COULD BE NASA’s cra­zi­est idea yet: the agency is plan­ning to drag an as­ter­oid into a sta­ble or­bit around the Moon. Once there, it will be vis­ited by as­tro­nauts who will test tech­nol­ogy be­ing de­vel­oped for fu­ture hu­man ex­pe­di­tions to deep space, in­clud­ing to Mars.

Dubbed the As­ter­oid Re­di­rect Mission (ARM), thee project will in­volve guiding an un­manned space­craft to a near-Earth as­ter­oid. Ro­botic arms on the craft will then cap­ture a 4m-wide boul­der from the as­ter­oid’s sur­face, be­fore mov­ing the whole she­bang into or­bit around the Moon. The craft won’t phys­i­cally tow the as­ter­oid: in­stead, it will use its own mass, com­bined with that al­ways been un­clear. Now, Duke Uni­ver­sity has found that male mice make the sounds to ser­e­nade fe­males.

What did they find?

Males sang louder, more com­plex songs when they could smell a fe­male’s urine, but could not see her. The songs were longer and sim­pler when the males of the boul­der boul­der, to ex­ert a grav­i­ta­tional at­trac­tion on the as­ter­oid and al­ter its path. In space, grav­i­ta­tional at­trac­tion can have a sig­nif­i­cant im­pact, even on fairly small ob­jects. The jour­ney is ex­pected to take sev­eral years.
