Solar sailing is an emerging propulsion technology that utilizes the momentum transfer from solar photons impinging on the sail to propel spacecraft without the need for stored propellant. The aim of this thesis is to analyze the reachability of the photo-gravitational libration point L1 of the Sun-Earth-Moon system, by employing a spacecraft propelled solely by a solar sail departing from a Low Earth Orbit (LEO). To do so, the overall mission is split into two phases: an Escape phase from the Earth-Moon system, and a transfer phase from the Earth-Moon system to L1. In the first part of the mission analysis, the present work answers the following question: What is the minimum altitude from which it is possible to escape from Earth? This problem is addressed by considering the effects of atmospheric drag and a near-optimal controller.
