F. Frisone,P. G. Morassorge solar sails in space. Germany’s DLR took particular interest in solar sail technology in the 1990s and fabricated one of the first large-scale ground-based engineering model sails. The Russians demonstrated in space a spinning 20-meter mirror, called Znamya, from their Progress resupply vehicle

Felix A. Gers,Jürgen Schmidhuber,Fred Cummins gentle push that makes a solar sail such a useful propulsion system. Unfortunately, the Sun is also the limiting factor in the overall usefulness of a solar sail. When a spacecraft gets far from the sun, there is simply not enough light available to provide additional propulsion. Recall the "invers

ng, as evidenced by flight tests of solar electric propulsion, solar sailing has yet to catch up with its long-term rival. As will be seen, however, some mission applications are absolutely unique to solar sailing and so represent a trump card for proponents of solar sailing to use to advance their

Gb. Cicioni,F. Masullictical experience led to a limited selection and ultimate evolution towards the standard aircraft configurations seen today, and perhaps the long-term development of solar sailing will follow a similar route. When practical experience of solar sails is at hand it may become apparent that there only
