The Voices of Mars (novel)

The Voices of Mars is a science fiction novel by Patrick Moore.

Some years after the events described in "Mission to Mars", Maurice and his friend Bruce Talbot are now permanent members of the research colony established on Mars. They learn from a new arrival that the United Nations, which funds the base, is having second thoughts about its viability.

Many of the colonists have been so long on Mars that their muscles have become acclimatized to the conditions and they would be unlikely to survive long under Earth conditions. Nevertheless, they decide to send an 'embassy' (the Voices) to earth to plead their cause. Maurice, his uncle Leslie Yorke, and Bruce Talbot make the trip.

Whilst in Earth orbit, they hear on radio a debate at the United National Scientific Council, which has been hijacked by a few self-serving politicians. The crew decide to land and try to address the debate. Despite being badly affected by Earth gravity and heat, they make it to the debating chamber. Maurice manages to convey his opinions on the importance of the Mars colony to the delegates, before collapsing. They are conveyed back to the spaceship and leave Earth. They later learn that attempts to close the base have been defeated.
