Abstract

With Fig. 3.3 we indicated that most of the cosmic ray landscape is void. Of course, it will be very important for future cosmic ray particle observations to fill most of the existing gaps. Some important observational goals for the future are:
  1. 1.

    What are the highest energies and the fluxes of cosmic ray nucleons and cosmic ray electrons?

     
  2. 2.

    Is there cosmic ray antimatter with Z ≥ 2?

     
  3. 3.

    What is the positron and antiproton fraction far above energies of 20 GeV? What is the isotope ratio of cosmic ray clocks like beryllium and aluminium at relativistic energies?

     
  4. 4.

    What is the elemental composition of cosmic ray nuclei at energies far above 1012 eV? And how does the cosmic ray anisotropy behave as a function of energy above 1014 eV ?
