35 years ago Sally Ride became the first American woman in space. But rather than focus on her own extraordinary achievements, her passion became boosting the number of girls pursuing STEM. Another pioneering astronaut remembers her friend and colleague.
Small satellites are launched to Low Earth Orbit - and then eventually burn up.
So long as small satellites are in low Earth orbit – and most likely they will be – the Earth's "vacuum cleaner" will clean them up.
The first piece of the International Space Station was launched in 1998.

Spend many months attached to the ISS and see how well you grow.
If you want to live on Mars, you're going to need to grow food. Seeds are naturally equipped to handle challenging Earth environments, but how well can they survive what they'll encounter off-planet?

Sperm that's been to space is good enough to get mice pregnant – and give birth to healthy offspring.
Look ma, no gravity!
Every moment of life on our planet has had the force of gravity in the background. But the prospect of long-distance space travel means it's time to figure out what happens to our biology in its absence.
