Science with GRASP

The GRASP mission — Gamma Ray Astronomy with Spectroscopy and Positioning — is currently under assessment by ESA as a future space astronomy mission. The GRASP telescope will be the first high-resolution spectral imager to operate in the gamma-ray region of the spectrum. This, coupled with its high sensitivity, will enable GRASP to address many basic questions related to the physics of celestial objects thus offering a major step forward in high-energy astrophysics.
