I find it amazing that we can read our DNA, and now the equipment is so small we could potentially do this in space.

On Monday, along with other supplies, NASA sent a small DNA sequencer into orbit, bound for the International Space Station.

It's hoped the astronauts can use it to monitor their health and analyse any microbes that might make them ill. But until they test it they won't know if it will work in microgravity.

One of these DNA sequencers is on display now, in the Science Museum's Antenna gallery.
