Space scientists' latest project is to send tiny, robotic space ships out in space to study asteroids.
Thirty or more microsatellites would swarm around the space rock gathering data.
What we want to know is what you would do if you could be miniaturised.
Would you pop into your mates' bodies and check out their internal organs, or would you get an ant to be your pet and go for rides on it?
I would go and explore Buckingham Palace and go and look in the Queen's bedroom!!! Then I could get through the guards easily enough!

If I was very small...I'd probably try not to be squished, or eaten by my dogs...
I would go to the Harry Potter Set and ride around in Daniel Radcliffe's pocket all day!!!!!!!!!!
