... migration, solar sail, giant star '''JBIS Reference Code ''' - 2010.63.74 '''Number of Pages''' - 4 Abstract Our Sun will eventually leave the main sequence and expand in size and luminosity to become a giant star. For ... . A space-manufactured beryllium solar-photon sail could be used for emigration from the solar system during this solar phase. Space environmental effects limit the closest approach distance to the giant star to around 0 ...

... the sail craft in the near-Sun space region. When spacecraft approaches the Sun there are at least two important factors that have an effect on the thickness of solar sail film and therefore on the reflection ability of the sail: the temperature dependence of electrical conductivity of sail material and existence of a wide range of solar electromagnetic radiation frequencies. Applying ...

... quite unique to solar sailing. These orbits have novel mission applications, many of which only require the use of only moderate performance solar sails. Since the orbits and applications are unique to solar sails, they are mission enabling rather than mission enhancing, compelling mission planners to develop and utilise solar sail technology. '''To BUY this ...

Sail kinematics, structure, and thermal aspects are considered. It is shown that solar-system exit velocities of ...

We numerically solve for solar sail trajectories and estimate escape ...

... of Driscoll and Vaughan–is first presented, followed by a consideration of various aspects of this theory, which allows estimation of reflectivity, transmissivity, absorptivity and emissivity of metallic mesh solar sails, under certain restrictive conditions. Three candidate mesh materials are then compared: aluminium, magnesium, and scandium. Aluminium, being superior, is chosen ...
