Following the successful flights of large area survey experiments on three unstabilised Skylark rockets in 1967, 8 and 9, the Leicester Group has now changed the emphasis of its Cosmic X-ray Astronomy programme to the detailed observation of specific sources using attitude-controlled vehicles. Two new Skylark experiments for flights in the current year are described and some details are also given of an X-ray polarimeter/spectrometer being prepared for launch in 1973 on the UK-5 satellite.
