Team finds evidence for carbon-rich surface on Ceres

A team led by Southwest Research Institute has concluded that the surface of dwarf planet Ceres is rich in organic matter. Data from NASA's Dawn spacecraft indicate that Ceres's surface may contain several times the concentration ...

Juno mission to Jupiter delivers first science results

NASA's Juno mission, led by Southwest Research Institute's Dr. Scott Bolton, is rewriting what scientists thought they knew about Jupiter specifically, and gas giants in general, according to a pair of Science papers released ...

The mystery of heavy elements in galactic cosmic rays

Scientists have used data from the Southwest Research Institute-led Magnetospheric Multiscale (MMS) mission to explain the presence of energetic heavy elements in galactic cosmic rays (GCRs). GCRs are composed of fast-moving ...

Team identifies clathrate ices in comet 67P
