The terrestrial planets and the asteroids dominant in the inner asteroid belt are water poor. However, in the protoplan-etary disk the temperature should have decreased below water-condensation level well before the disk was photo-evaporated. Thus, the global water depletion of the inner Solar System is puzzling. We show that, even if the inner...

The evolution of the meteorite flux to Earth can be studied by determining the terrestrial ages of meteorites collected in hot deserts. We measured the terrestrial ages of 54 stony meteorites from the El Medano area, in the Atacama Desert, Chile, using the cosmogenic nuclide Cl-36. With an average age of 710 ka, this collection is the oldest...
