Man has walked on the moon and in space, but what other physical feats can be performed in zero gravity? What if men and women were to travel to Mars, a mission that might take around two years to complete. Considering astronauts would be in close quarters for the duration, some argue that it's only a matter of time and biology that sex will happen. Regardless, NASA remains silent on the subject. As FOX News reports, the Journal of Cosmology recently explored the issue with a special issue, “Sex on Mars.” 

 

 

 

But have they? As The Guardian reports, Pierre Kohler is a science writer who claims that sexual interactions have happened on both NASA and Russian space missions. As Kohler told The Guardian, "The issue of sex in space is a serious one. The experiments carried out so far relate to missions planned for married couples on the future International Space Station, the successor to Mir. Scientists need to know how far sexual relations are possible without gravity." But Kohler cited a “confidential” NASA report about a 1996 space shuttle mission in which different sexual positions in space were explored. This report was later determined to be a hoax.
