Comet Enthusiast

Astronomer Royal Martin Rees, Professor of Cosmology and Astrophysics at Cambridge University, believes that planets resembling Earth may be discovered in the next two to three years - although it may take a further 20 years before we are able to capture an image of them. Rees also believes that the need for manned space exploration is rapidly diminishing in the face of new technologies and advances in robotics, an that explorers walking on the surface of planets like Mars in the future are likely to be adventurers of the sort who conquered Everest, rather than astronauts on state-backed missions of the type NASA undertake.
