Sex and Intimacy in Weightless Environment (06:55)
Sexual intimacy in weightlessness is challenging. A couple tests special garments aimed at helping people having sex in space by keeping them together in a "two-suit."
Animal Reproduction Studies in Space (04:43)
In a weightless environment human bones lose calcium, and the heart, muscles, blood, and plasma lose mass. Another challenge is high energy radiation. Animal reproduction in space reveals certain abnormalities in offspring.
Sex in Zero Gravity (02:00)
Male astronauts often report prolonged erections in a micro-gravity. Some studies show that sexual desire decreases in weightlessness. Long-term exposure to space radiation could damage male and female reproductive glands.
Fertilization and Fetal Development in Space (05:54)

At NASA, sex is a taboo topic. No one admits to having sex in space. NASA does not openly forbid sexual relations; it simply assumes that astronauts will sublimate sexual desire.
Sex in Space (04:44)
Sex in space comes with certain advantages and disadvantages. The physics of micro-gravity sex complicate physical coupling. Scientists and engineers design restraint systems for space sex.
Private Space Industry (03:02)
Americans realized that common people were not going to be part of space travel, so they turned their attention elsewhere. Virgin Airlines' Richard Branson plans commercial flights to the edge of space--62 miles up.
Space Tourism (04:29)
