The fact that x-ray astronomy could yield cosmological information was apparent in the earliest rocket flights carried out in 1962 and 1963 (Giacconi et al, 1962, Bowyer et al, 1963). These flights established that diffuse radiation was present around the sky; indeed one of the first theoretical papers commenting on the x-ray results was by Fred Hoyle (1963) showing that the observed background flux was below that predicted for the hot, steady-state universe. A few years later, the first discrete source was credibly identified with an external galaxy (Byram, et al. 1966).
