The race is on between the nation of Selene on the Moon and the International Astronautical Authority to build a series of telescopes to view a discovered object several light years away that could potentially harbor life with similar conditions to those on the Earth. When the mirror being constructed for the telescope on the moon is accidentally damaged, the director decides to use nanotechnology to repair the mirror, saving time and money. What follows is one accident after another as the Farside installation tries to simultaneously build the mirror and deal with the potential of the site being shut down due to dangerous conditions. This is somewhat shorter than Bova's previous works dealing with this subject in similar situations, but no less enjoyable as it seems Bova is setting up for novels and stories that will begin outside our solar system. The Grand Tour is expanding.....
