New experiments reveal that impact melts and breccias capture up to 30% of the water carried by carbonaceous chondrite\u2013like projectiles under impact conditions typical of the main asteroid belt impact and the early phases of planet formation. This impactor-derived water resides in two distinct reservoirs: in impact melts and projectile survivors. Impact melt hosts the bulk of the delivered water. Entrapment of water within impact glasses and melt-bearing breccias is therefore a plausible source of hydration features associated with craters on the Moon and elsewhere in the solar system and likely contributed to the early accretion of water during planet formation.&#8221;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>R.
