After a drink or two, having sex is a natural inclination. Will the lack of gravity be a problem? (It could lead to some interesting "positions"). A trip to even one of our closest stars would take decades and possibly even hundreds of years, spanning multiple generations.

But scientists aren’t sure humans can procreate safely in the microgravity of space. So far, humans haven’t managed to send a probe beyond even our own solar system, let alone to the nearest star more than 4 light-years away. A light-year, the distance light travels in a single year, is about 6 trillion miles.

During the STS-80 mission, which was launched on November 19, 1996, the Space Shuttle Columbia took a crew of five astronauts on an 18 day trip around the Earth, the longest flight in the history of the shuttle. During the flight, astronaut Story Musgrave looked out the shuttle windows and saw a large, disc-shaped object. After years of silence, he’s finally started talking about it. The UFO was large–between 50 and 150 feet in diameter–and the outer rim was rotating in a counter-clockwise direction. During the incident, Musgrave said, "I don’t know what it is. Whether it’s a washer, debris, ice particles, I don’t know. But it’s characteristic of the thousands of things which I’ve seen. What is not so characteristic is it appears to come from more

There was a moment of panic down here on earth last week, when the computers aboard the International Space Station (ISS) that control the supply of oxygen and water crashed. As scientists and engineers struggle to get the computers working again, a physicist declares that the ISS is a waste of time and money.

Robert L. Park, author of Voodoo Science, thinks we should not be sending astronauts in space, and has even testified before Congress on this subject. He says, “This is yet another example of why the station is not worth all the trouble.” He says his views are shared by a large part of the scientific community, although many feel constrained about publicly discussing their views.

Last November, we reported that astronauts on board the International Space Station heard a strange noise, as if something was hitting the ISS from space. Now they’ve heard the same sound again.

In November, astronaut Mike Foale said, “It sounded like a metal tin can kind of being expanded and compressed. It was a noise that lasted about a second. It sounded like an impact or something.”
