According to astronomers, the comet Siding Spring will make an extremely close approach to Mars on 19 October 2014 (see Wikipedia and NASA).
October 19 is the final date of the Synod being held this year of 2014, the Synod which will ultimately lead to a great schism as afterwards (exact timing TBD) the teachings of the Church will be changed with the approval of Francis. You can already see the redefinition of natural law already described in the official Synod document.
Expect to see an astronomical sign on the Synod’s final date of October 19. Mars and/or its small moons (Phobos and Deimos) will not escape being affected by comet Siding Spring, which will have other effects in the solar system at a later time.
