Response To Comment On "Ancient Asteroids Enriched In Refractory Inclusions"

Although the exact abundance of phases in carbonaceous chondrites remains debatable, a potentially lower absolute abundance of calcium- and aluminum- rich inclusions (CAIs) in the Allende meteorite does not change our fundamental conclusion. In a relative comparison, CAI- rich asteroids contain two to three times as many CAIs as the most CAI- rich meteorites. These asteroids are therefore greatly enriched in the earliest solar system materials and remain enticing targets for future exploration.
