This was published in January, and look at all the Mars mission stuff that has popped up since. I wonder what a follow up would read like? I'm guessing they're using his Mars algorithm?

Those Aldrin Cyclers are kind of a strange beast -- possibly useful in a speculative-fiction kind of way, but take more delta-v than a Hohmann transfer orbit and have a very high relative velocity as they pass Earth and Mars, which makes getting cargo to them tricky (the "taxis" have to make a hyperbolic rendezvous with the cycler, and a missed encounter would likely result in a very long tour of the solar system). Instead, NASA envisions using near-Hohmann orbits for getting advanced cargo to Mars; human travel would use the usual hyperbolic transfer orbit.

Most people outside of NASA still consider a standard Hohmann-like orbit for getting people to Mars too.

It's dated January 2015, not 2014.

How could it possibly be dated January 2015??

EDIT: I mean, indeed it is, but we're like, you know, still in 2014
