Between 1969 and 1972, twelve American men walked on the moon. Since then, no manned spacecraft has ever landed on any astronomical body except the Earth itself.

There are various plans to send humans to the moon and to Mars - but when will the first manned spacecraft touch the surface of any planet or moon other than Earth, Earth's moon, or Mars?

This question resolves positively when any spacecraft containing living humans comes into physical contact with any planet, dwarf planet, or moon other than Earth, Earth's moon, or Mars according to the agency, corporation, or other body primarily responsible for the mission.

The landing need not last for any significant period of time and the crew need not survive impact for a positive resolution, but must be alive when the impact occurs. Making physical contact with other bodies such as asteroids, comets, or 'minor planets' not considered 'dwarf planets' does not count.

Resolves ambiguously if it cannot be conclusively determined whether or not any members of the crew are alive at the moment the spacecraft makes contact with the surface of the astronomical body. A crew of only EMs will not count toward positive resolution.
