We’ve only travelled into space in the last century, but humanity’s desire to reach the moon is far from recent.
Who’s rushing? The Chinese Long March 5 rocket lifts off.
Dreams of new footprints on the moon are more about domestic politics than foreign policy.
Deep-space journeys will have plenty of downtime.
Astronauts traveling to Mars and beyond would face serious psychological challenges. A well-designed media program – based on an old-fashioned schedule – might help make life at least a bit easier.
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?

In conversation: Martin Rees.
The Astronomer Royal answers some of the world's – and the universe's – biggest questions.
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.
