Cosmic Ray Energetics And Mass (CREAM) launch and operations, PSU Co-I
Project Description
This proposal covers the activities of the Penn State group on the BACCUS high-altitude balloon experiment in Antarctica and on the CREAM mission to the ISS. These projects together will achieve definitive measurements of the cosmic-ray elemental spectra into the PeV range (nuclei) and of cosmic-ray electrons into the TeV range, as well as detailed studies of secondary nuclei (such as B or the sub-Fe elements). These are the experimental measurements needed to sort out the details of cosmic-ray acceleration and propagation in the Galaxy, a long standing puzzle in particle astrophysics.
More »Anticipated Benefits
The Astrophysics Research and Analysis program (APRA) supports suborbital and suborbital-class investigations, development of detectors and supporting technology, laboratory astrophysics, and limited ground based observing. Basic research proposals in these areas are solicited for investigations that are relevant to NASA's programs in astronomy and astrophysics, including the entire range of photons, gravitational waves, and particle astrophysics. The emphasis of this solicitation is on technologies and investigations that advance NASA astrophysics missions and goals.
