Satellites crashing in space - Russian and US satellites

One always thinks of space as a large open area, with plenty of space in all directions. You combine this space with the concept of satellites being well regulated and following controlled orbits, and then it is difficult to believe that satellites under the control of such countries such as the United States and Russia could actually collide, and yet that is exactly what seems to have happened:

The collision between a U.S. and a Russian satellite over Siberia may have been accidental and the first of its kind, but experts say more crashes will inevitably occur and could have geopolitical consequences. "This is an event that really makes us realize that things are not so straightforward as we originally thought," said Francisco Diego, a senior research fellow in physics and astronomy at University College London.
The collision, between a spacecraft operated by U.S. communications group Iridium Satellite LLC and a Russian Cosmos-2251 military satellite, happened 485 miles above the Russian Arctic on Tuesday afternoon. The crash sent at least 600 pieces of debris off into space, officials said, increasing the risk that other satellites, including the vast International Space Station, which orbits 220 miles up, could be struck and damaged.

This crash may have been accidental, but what is to prevent countries from investing in such technologies. For example, a couple of such crashes have the effect of impacting the GPS and communication technologies that are used by the US military to great affect.

Having sex in space

As the industry of commercial space travel starts to take off, with tickets being sold for sub-orbital space travel, there would be a number of people who would want to expand on the concept of the mile-high club (having sex when in an plane). The sheer thought of being able to have sex in space must be sending many couples on a high, after all, James Bond has done it in the movies. And there would be the thrill of having your name in the Guinness Book of Records as being the first couple to actually do it when in space. But Doctors are not so sure about how much it would be possible:

LONDON: An increasing number of couples expressing their desire to have sex in space have become a cause of concern for scientists, says a report. The experts do not think that it would be possible to have intercourse in space. "We've had a variety of people inquire about it," Daily Star quoted Will Whitehorn, president of Virgin Galactic, whose boss Richard Branson hopes to put tourists into space next year, as saying.
Experts guess that realising sex in space would require spacecraft like the Shuttle to be installed with special "love handles" that would control astronauts floating around.

Of course, it is going to happen sooner or later, so it makes sense for people to start thinking about it.
