We study shrinking targets problems for discrete time flows on a homogeneous space Gamma\G with G a semisimple group and Gamma an irreducible lattice. Our results apply to both diagonalizable and unipotent flows and apply to very general families of shrinking targets. As a special case, we establish logarithm laws for cusp excursions of unipotent flows, settling a problem raised by Athreya and Margulis.
