A new paper on the Tarda and Tagish Lake meteorites by BCMS Deputy Director Devin Schrader and colleagues (including Center Alumns Jemma Davidson, Zack Torrano, and Greg Brennecka) shows how similar they both are, and suggests that D-type and P-type asteroids may be fragments of the same parent body. We also identified potential parent asteroid sources for Tarda and Tagish Lake.

In addition, new research on Tarda and other carbonaceous chondrites by BCMS Curator Laurence Garvie and colleagues (including ASU’s Christian Hoover), has found that aqueously altered carbonaceous chondrites have high nanoporosity that make them act as ‘nanosponges’ once on Earth. They rapidly soak up water just from the atmosphere!
