Mars is back. Suddenly everyone - from Elon Musk to Ridley Scott to
Donald Trump - is talking about going to the Red Planet. When the Apollo
astronauts walked on the Moon in 1969, many people imagined Mars would
be next. However, NASA's Viking 1, which landed in 1976, was just a
robot. The much-anticipated crewed mission failed to materialise,
defeated by a combination of technological and political challenges.
Four decades after Viking and almost half a century after Apollo,
technology has improved beyond recognition - and politics has changed
just as much. As private ventures like SpaceX seize centre stage from
NASA, Mars has undergone a seismic shift - no longer just about science,
it's become the prime destination for future human expansion and
colonisation. But what's it really like on Mars, and why should anyone
want to go there? How do you get there and what are the risks?
Astrophysicist and science writer Andrew May answers all these questions
and more, as he traces the history of our fascination with the Red
Planet.
