Observing Earth Satellites

Well over a thousand artificial satellites are now in orbit round the earth, and some can be seen as bright lights crossing the stars. Patrick Moore talks to Desmond King-Hele, F.R.S. about the way amateur observers can sight and track satellites, and about the value of these observations to space research.

Gas-Clouds in Space

Patrick Moore and Dr. V. Barocas talk about the nebulae - clouds of gas of many kinds far out in space. In some of these, new stars are coming into existence.

The Craters on the Moon

Close-up photographs of prospective lunar landing-sites are rapidly increasing our knowledge of the moon's surface. But how strong is the evidence that the lunar craters were formed by the same kind of volcanic activity as Earth calderas? Patrick Moore puts this question to a geologist, Dr. G.J.H. McCall.

A new look at Mars

Invisible Astronomy

Patrick Moore and Colin Ronan discuss the increasing study of non-visible radiations from space which is dramatically widening our knowledge of the universe.

Cameras round the Moon

In the just-completed NASA Lunar Orbiter programme, five photo-laboratories have orbited the moon at 4,500 m.p.h. Patrick Moore talks to H. J. P. Arnold about the sophisticated techniques involved in spacecraft photography.
