1.0 - Team Members and Their Roles Shreyas Bidadi ( bshreyas@yorku.ca ) - Project Manager. Will be responsible for deciding upon the best sail material and analyze the performance of the sail through calculations. Will also be responsible for assembly of all reports. Ryan Orszulik ( orszulik@yorku.ca ) – Will be responsible for webpage design, editing of reports, and for modeling and developing control and steering algorithms as well as analyzing theoretical background and models. . Alexander Dolgansky ( alexd221@yorku.ca ) – Will be responsible for modeling and analyzing structural loads, forces produced on the sail in its operation, and material variation. The role of secretary will be rotated between the team members according to what section of the sail is of current interest. We also have a joint e-mail account, solarsail06@gmail.com where all of us can be reached at one time. The website is http://www.students.yorku.ca/~orszulik/Home.html 2.0 - Introduction The solar sail is a relatively simple and elegant propulsion method, as it does not require a complex engine or the ability to carry fuel onboard the spacecraft. The solar sail moves due to solar radiation pressure, which is basically photons of light striking the solar sail being reflected, and as a result exchanging their momentum with the highly reflective sail. Since the acceleration is directly related to the solar radiation pressure, and the solar radiation pressure
