Ask a Scientist: Is there life on Mars?

Today’s questions about space are a little bit less about standing on the ground looking up, and a bit more about getting into space ourselves. The answers are brought to you by AC, who is not an astronaut, despite wanting to be one until about year 10, when she realised she was going to be too short. (Who knew there were height limits on rockets?). Also, Australia STILL doesn’t have a space program, which she finds really annoying…
