Hi, I was wondering when Luna transiting the Earth will be visible from Mars.

Or a double transit where Earth is transiting Sol and Luna is transiting Earth at the same time.

On what dates will you be spending your vacation on Mars? :confused:

From the point of view of Martians, the Moon will transit Earth at the same time that the Moon occults Mars for earthbound observers. This will next occur on 2013 MAY 09. You just missed the occurrence of 2012 SEP 19. :)

Although the Moon will not appear to simultaneously transit the Earth, the next transit across the Sun by the Earth as viewed from Mars will occur on 2084 NOV 10. The Moon will transit the Sun at about the same time. That should give you plenty of time to prepare for your visit! ;)
