The BBC news reported that a group of scientists and engineers are working to reestablish contact with the Prospero spcaecraft, the first (and only) UK satellite to be launched on a UK vehicle. Launched atop a Black Arrow rocket on 28 October 1971, it carried a series of experiments to investigate the effects of the space environment and was contacted annually until 1996 when the project was discontinued.
