  Astrophysics is gaining increased attention from the particle and nuclear
physics communities, as budget cuts, delays, and cancellations limit
opportunities for breakthrough research at accelerator laboratories.
Observations of cosmic rays (protons and nuclei), gamma rays and neutrinos
present a variety of puzzles whose eventual solution will shed light on many
issues ranging from the nature of fundamental interactions at extreme energies
to the mechanisms of astrophysical sources. Several important detectors are
just beginning full-scale operation and others are beginning construction.
