We have sent a lot of strange things into space, and there is no sign that we will stop putting weird things into space any time soon. From light sabers to sea urchins, it doesn't seem like there is any limit to what we will send into space. Another thing we have sent into space is bacteria. Scientists were curious about what would happen to bacteria in space, and they found the answer after they sent some salmonella for a journey and then tested it on animals when it came back to earth. They found that the space bacteria had grown much stronger. Because of that, cleanliness in space is of utmost importance. The cost of sending things into space are very high so it must have cost one space tourist a lot of money to get a seat on a rocket headed to the International Space Station. It takes a huge amount of energy to get a rocket free of Earth's gravitational field and for each additional body you have to add a lot of weight in terms of body mass as well as all of the supplies that each person needs to survive.
In the name of science, NASA and various organizations have sent dozens of random things into outer space. Here are the geekiest and weirdest ones.
