re: Cyclers

That you first want to just ignore unpleasant facts and second want to scribe irrational, cult or even evil views to your opposition is well know...

***The cycler from Earth to Mars would make that trip in about six months, but not return to Earth for another two years or more. Another cycler would have an orbit that would go from Earth to Mars in that longer arc, but cover Mars to Earth in the shorter course of six to eight months. Thus, travelers would never have to take the longer leg of the orbit.

However it works out, travelers to Mars will need a really good friend to collect their mail and turn on the porch light. "A non-stop flyby of Mars would take at least two and one-half years," Longuski said. "If they stop on Mars, they have to stay long enough for the next cycler. That will easily make a trip of more than three years."

That is why three cyclers would be needed, Aldrin said.***
