Sir Fred Hoyle and John Elliot’s 1962 A For Andromeda is the first of two Andromeda novels. It is a novelization of Hoyle and Elliot’s 1961 television SF serial drama of the same name.
In the distant future of 1970, Britain is increasingly under the sway of an America on whom the British are dependent for defense against the Warsaw Pact nations. Once a mighty imperial power, now it enjoys also-ran status. It does have one accomplishment of which it can be proud: the Bouldershaw Fell Radio Telescope, the most powerful radio telescope on Earth.
Almost immediately following Bouldershaw’s activation, the grand device detects a signal coming from a star in the direction of the constellation Andromeda.
