We are in the middle of an experiment right involving tomatoes and space. Now, I know you are probably wondering what the two have in common. The Canadian Space Agency is involving schools in an experiment to test whether or not it is possible for plants to grow food in space – in zero gravity environments. This is the only way we are going to get astronauts to places like Mars as there is not enough space to carry the amount of food needed to reach there and back without being able to grow our own food.

As part of the experiment, we are growing two types of seeds; seeds that have been in space and thus have been exposed to zero gravity and ordinary seeds. However, we do not know which ones are which as the Agency does not the results to be biased.

In our discussions about growing plants in space as a way to get to Mars without starving we came across the video that gives a sense of the size comparison of planets and stars that I thought everyone would enjoy.
