Buzz Aldrin has said that NASA should stop spending $3.5 billion per year on the International Space Station and relinquish low Earth orbit activities to private companies, such as SpaceX, Orbital ATK, Boeing, Bigelow Aerospace, and Axiom Space. This would allow for the funding of "cyclers" to enable a base on the moon and eventually a permanent presence on Mars:
Establishing private outposts in LEO is just the first step in Aldrin's plan for Mars colonization, which depends heavily on "cyclers" — spacecraft that move continuously between two cosmic destinations, efficiently delivering people and cargo back and forth. "The foundation of human transportation is the cycler," the 87-year-old former astronaut said. "Very rugged, so it'll last 30 years or so; no external moving parts."
Step two involves the international spaceflight community coming together to build cyclers that ply cislunar space, taking people on trips to the moon and back. Such spacecraft, and the activities they enable, would allow the construction of a crewed lunar base, where humanity could learn and test the techniques required for Mars colonization, such as how to manufacture propellant from local resources, Aldrin said. Then would come Earth-Mars cyclers, which Aldrin described as "an evolutionary development" of the prior cyclers.
[...] NASA officials have repeatedly said that the ISS is a key part of the agency's "Journey to Mars" vision, which aims to get astronauts to the vicinity of the Red Planet sometime in the 2030s.
Is the ISS a key part of the "Journey to Mars" or a key roadblock?
The Trump Administration's plan to hand the International Space Station off to the private sector by 2025 probably won't work, says a government auditor. It's unlikely that any commercial companies will be able to take on the enormous costs of operating the ISS within the next six years, the auditor said.
NASA's inspector general, Paul Martin, laid out his concerns over the space station's transition during a Senate space subcommittee hearing May 16th, helmed by Sen. Ted Cruz (R-TX) and Sen. Bill Nelson (D-FL). During his testimony, Martin said that there's just no "sufficient business case" for space companies to take on the ISS's yearly operations costs, which are expected to reach $1.2 billion in 2024. The industries that would need the ISS, such as space tourism or space research and development, haven't panned out yet, he noted. Plus, the private space industry hasn't been very enthusiastic about using the ISS either — for research or for profit. "Candidly, the scant commercial interest shown in the station over its nearly 20 years of operation gives us pause about the agency's current plans," Martin said at the hearing.

In a move intended to align with the National Space Council's call for NASA to return to the Moon, the United Launch Alliance intends to launch a Bigelow Aerospace B330 inflatable module into low Earth orbit, and later boost it into lunar orbit using a rocket which can have propellant transferred to it from another rocket:
Bigelow Aerospace, a company devoted to manufacturing inflatable space habitats, says it's planning to put one of its modules into orbit around the Moon within the next five years. The module going to lunar space will be the B330, Bigelow's design concept for a standalone habitat that can function autonomously as a commercial space station. The plan is for the B330 to serve as something of a lunar depot, where private companies can test out new technologies, or where astronauts can stay to undergo training for deep space missions.
"Our lunar depot plan is a strong complement to other plans intended to eventually put people on Mars," Robert Bigelow, president of Bigelow Aerospace, said in a statement. "It will provide NASA and America with an exciting and financially practical success opportunity that can be accomplished in the short term."
To put the habitat in lunar orbit, Bigelow is looking to get a boost from the United Launch Alliance. The B330 is slated to launch on top of ULA's future rocket, the Vulcan, which is supposed to begin missions no earlier than 2019. The plan is for the Vulcan to loft the B330 into lower Earth orbit, where it will stay for one year to demonstrate that it works properly in space. During that time, Bigelow hopes to send supplies to the station and rotate crew members in and out every few months.
After that, it'll be time to send the module to the Moon. ULA will launch two more Vulcan rockets, leaving both of the vehicles' upper stages in orbit. Called ACES, for Advanced Cryogenic Evolved Stage, these stages can remain in space, propelling other spacecraft to farther out destinations. ULA plans to transfer all of the propellant from one ACES to the other, using the fully fueled stage to propel the B330 the rest of the way to lunar orbit.
