Project Mercury was the first human spaceflight program of the United States. Its goal was to put a man into Earth orbit and bring him back safely, ideally before the Soviet Union (under the Vostok programme). Although it failed to launch the first humans to space, its success laid the groundwork for Project Gemini, which in turn paved the way for Project Apollo to put the first people on the Moon by the end of the 1960s.
- Due to limitations on surviving orbital and suborbital trajectory data, this addon only includes the following missions: MR-3, MR-4, MA-4, MA-5, MA-6, MA-7, MA-8, and MA-9
- Replaces the stock installation of the last three Mercury orbital flights (MA-6 to 9)
- Since almost all Mercury missions lasted only a few hours, refer to the table below and follow this Tutorial on how to view them on Celestia.
