In at least three patriarchal blessings from Joseph Smith Sr., we have a promise given that the person could be empowered to travel to (1) different worlds/planets and (2) the moon itself, providing insights into the cosmology of early Latter-day Saints:
Thou must preach the Gospel of
thy Savior to the inhabit—inhabitants of the earth, Thou shalt become a mighty
man in the Earth—Thou shalt have great faith—even like that of the Brother of
Jared.— thou shalt have power to translate thyself from one plannet [planet] to
annother [another]—power to go to the moon if thou shalt desire it. Power to
preach to the spirits in prison — power like Enoch to translate thyself to
heaven, — thou shalt have power to rend the vail [veil] of heaven and see Jesus
standing at the right hand of his Father. Theare [There] shall not be a
mightier man on Earth than thou. Thy faith shall increase and grow stronger and stronger it shall be
liken like that of Peter thy shadow shall restore the sick— the diseased shall
send to thee their handkerchiefs and aprons and by thy touch their owners shall
be healed. Thou shalt have power over unclean spirits; at thy command the
powers of darkness shall stand back, and Devils shall flee away. If it be
expedient the Dead shall rise and come forth at thy bid[d]ing even those that
have long slept in the dust shall come foarth [forth] to life. (Patriarchal
blessing of Lorenzo Snow, December 15, 1836 in H. Michael Marquardt, comp., Early
Patriarchal Blessings of The Church of Jesus Christ of Latter-day Saints [Salt
Lake City: The Smith-Pettit Foundation, 2007], 95)
and inasmuch as thou shalt put
thy trust in God, he will deliver thee and thou shalt go forth as upon the
wings of Eagles, from city to city & from land to land, and from world to
world, and preach the gospel in other planets and save many. (Patriarchal
blessing of Julius Thompson [not dated but either 1835 or 1836] in ibid., 96)
Thou shalt have power to abide to
the end and to translate thyself away if thou desire from place to place and
preach to different nations. . . . Thou shalt be transalted and preach to other
worlds, even from planet to planet and to spirits in prison. (Patriarchal
blessing of Solomon Warner Jr. in ibid., 146)
