  I derive a mode-coupling theory for the velocity autocorrelation function,
\psi(t), in a fluid of randomly driven inelastic hard spheres far from
equilibrium. With this, I confirm a conjecture from simulations that the
velocity autocorrelation function decays algebraically, \psi(t) ~ t^{-3/2}, if
momentum is conserved. I show that the slow decay is due to the coupling to
transverse currents.
