For this project, I used the HGS-1 incident to narrate the pros and cons of using lunar flybys to launch a satellite into geo-synchronous orbit.

The HGS-1 incident led to the discovery of a technique that provides new hope for unsuccessful launch attempts, as well as an efficient way of launching new satellites. While the traditional technique is effective, its high energy cost is unappealing. A properly timed lunar flyby can result in significant savings to the operator by either reducing the fuel consumption and/or increasing the payload mass.

The new technique is not risk-free. However, despite risks, this new approach does offer mission planners an extra, potentially cost-saving tool.
