Low-energy transfers to the Moon with long transfer time

An interesting paper about getting to the moon in thr most efficient way, if you're not in a hurry (and yes, it's cheaper and faster than Mars) https://t.co/uV416NmNsn

This paper is the second of pair of works I wrote with the Japanese colleagues K. Oshima and T. Yanao. Both of them are spin offs of my 2013 paper "On optimal two-impulse Earth–Moon transfers in a four-body model" published on CMDA as well. https://t.co/LA

The picture of the possible transfer solutions to the #Moon extended in the new paper by our @FrancescoTop by including trajectories with long transfer times https://t.co/8r5M8oJOnw https://t.co/NnCokKJ9Bi
