Re: 202*? and then there might be 2 stations in LEO

Cycler's are definitely the next step in a deep space habitat but the way I look at space stations is the more the merrier as that gives more oportunity to get more people into space and to get a great number of businesses providing services....If we up the flight rate we lower the cost.....

You can see by this chart that physical access to a cycler space station, is going to be limited.

The Aldrin Cycler passes the Earth, once every 2.135 years, (780 days) the Earth/Mars transfer time is 146 days. I am thinking we would want one cycler, the 146 day transfer time should be from Mars to Earth, and save the other 634 days for getting to Mars, because if we use Mars Direct, the astronauts will be traveling on the outbound leg in a Mars hab. The Mars Hab will contain enough supplies to last the outbound leg, plus the entire surface stay on Mars. Then we have the Earth Return Vehicle, the purpose of it will be to match velocities with the cycler, it will just be big enough to carry all the astronauts, a few meals plus the rocks they collected to the cycler. the cycler arrives in the vicinity of Mars unmanned, but with supplies sufficient to get the astronauts back to Earth in comfort, and, just as in The Martian, the Earth Return Vehicle will have an Orion Capsule attacked to it, the Earth Return Vehicle would then depart the cycler and use its remaining fuel to alter its orbit from the cycler so that it intercepts the Earth's atmosphere, the capsule then seperates from the Earth Return vehicle with its load of Mars rocks and the astronauts, the lander portion burns up in the atmosphere, while the capsule orients its blunt heat shield for reentry and perhaps a splashdown after the parachutes are deployed.

Re: 202*? and then there might be 2 stations in LEO

While the topic started about the possible breakup and one partner chosing to take there ball and go home I think we can open this up to having other stations put into orbit by others. It maybe that way if its not re-extended after 2024 again postponing its deorbit to after 2028....

Private space station coming soon? Company aiming for 2020 launch

The builders of the Axiom International Commercial Space Station aim to enlarge the landscape of low-Earth orbit, to create what they view as a “historic shift” in human spaceflight.

Making a space outpost available to nations, organizations and individuals could help make living and working in Earth orbit commonplace and support the exploration of deep space, Axiom representatives said.

Orion Span falls far short of funding goal to support its commercial space station ambitions

Orion Span claims it can launch a one-module space station, called Aurora Station, by 2022 for space tourism, but an equity crowdfunding campaign to support the company's plans fell far short of its goal.

Re: 202*? and then there might be 2 stations in LEO

It ems that Russia is looking again to ending the partnership in space with Russia's Energia suggests building national space station

Its had a few mishaps and investigations into a leak found in the Russian component module and for some its after 2025 the modules are likely to keep breaking down.

Energia estimates potential expenses on supporting the ISS to be 10-15 billion rubles [$130-198 million likely, per year].

The new station, officially named the Russian orbital service station, is expected to have three to seven modules and may host a crew of two to four people.

The deputy director-general of Energia later specified that Russia is not planning to give up on the International Space Station (ISS).
