The contracted batch of 15 Saturn Vs were enough for lunar landing missions through Apollo 20. NASA publicized a preliminary list of eight more planned landing sites, with plans to increase the mass of the CSM and LM for the last five missions, along with the payload capacity of the Saturn V. These final missions would combine the I and J types in the 1967 list, allowing the CMP to operate a package of lunar orbital sensors and cameras while his companions were on the surface, and allowing them to stay on the Moon for over three days. These missions would also carry the Lunar Roving Vehicle (LRV) increasing the exploration area and allowing televised liftoff of the LM. Also, the Block II spacesuit was revised for the extended missions to allow greater flexibility and visibility for driving the LRV.
What would the latter Apollo missions carry to the moon to increase exploration? What was redesigned to allow better maneuverability in the LRV? How many more landing sites for the Apollo missions did NASA have planned? How long would the astronauts be project to be able to stay on the moon for in the latter missions? What would have to be increased regarding the LM and CSM for the last five missions?
