UK4 - the scientific satellite built by B.A.C. at Bristol - was launched into earth?
UK4 - the scientific satellite built by B.A.C. at Bristol - was launched into earth orbit on Saturday, 11th December, at 20.47 G.M.T. from Western Test Range, California, by a NASA/LTV/Scout Rocket. All went according to plan and the almost circular orbit which will cover almost all of the earth's surface has been achieved. UK4, now renamed Ariel IV, is travelling around the earth once every 95 mins. at a height of approximately 330 miles. The five scientific experiments carried are to be progressively switched on.
The University of Birmingham have two experiments to measure electron temperature and density.
The University of Sheffield have a very low frequency counter and a lightning impulse experiment.
The University of Manchester, Jodrell Bank, and S.R.C. R.S.R.S. experiments will measure ionospheric radio noise in the megahertz band.
The University of Iowa will measure low energy proton and electron intensity.
