Orion 15 is a planned NASA mission that will see the third Constellation lunar landing in conjunction with the LSAM 5, making this flight the ninth lunar landing conducted by NASA since July 20, 1969 (the six Apollo landings plus, if sucessful, the two previous Constellation landings).
Although currently not part of the initial fourteen mission schedule released in 2006, Orion 15/LSAM 5 will most likely be the first mission conducted by NASA in which all four crew members land on the lunar surface in LSAM 5, while the Orion 15 spacecraft is left unmanned in lunar orbit. This will allow NASA the opportunity to fly more scientist-astronauts (and even NASA educator-astronauts or astronauts/cosmonauts from other nations such as Russia, Great Britain, or France) onto the lunar surface, as Orion 13/LSAM 3 and Orion 14/LSAM 4 may be restricted to just a single scientist-astronaut due to the need to have three pilot-astronauts (commander, CEV pilot, and LSAM pilot) for those two missions. The practice of cross-training pilot-astronauts was done in the Apollo Program, but were slightly relaxed in 1973-74 for the three manned Skylab missions when a physician or scientist-astronaut flew with the two pilot-astronauts to the station.
The mission is planned to last approximately 21 days. Orion 15 will be launched by an Ares I from Kennedy Space Center's pad 39B. It will dock in Low Earth Orbit with a package made of an Earth Departure Stage (EDS) and the fourth LSAM. This package will have been launched in June 2020 atop of the heavy-lift Ares V rocket. The space assembly will be then be injected towards the Moon by the EDS.
