Welcome to the NASA solar Polarization and Directivity X-Ray Experiment (PADRE) mission software repository. PADRE is a small satellite mission whose purpose is to study particle acceleration during solar flares. The solar PolArization and Directivity X-Ray Experiment (PADRE) is a 12U small satellite observatory that will observe the Sun in hard X-ray from low earth orbit. PADRE will investigate particle acceleration processes that occur in large solar flares with two unique and complementary approaches
- by observing the polarization of the x-ray emission and
- by coordinating with Solar Orbiter/STIX to make the first two point measurements of x-rays and to determine their directivity.
PADRE hosts two instruments:
- solar HARd x-ray Polarimeter (SHARP) led by the Space Sciences Lab at UC Berkeley
- Measuring Directivity to Determine Electron Anisotropy (MeDDEA) led by the Heliophysics Division of the NASA Goddard Space Flight Center
