CATALYST presents two part science special Mars: Our Second Home?


Mars has long held our fascination; we have sent probes and rovers, now the time has come to send humans.

In the first of a two-part Mars special, astrophysicist Prof Tamara Davis and astronomer Greg Quicke meet the Australian scientists who are reaching for the stars as they attempt to overcome the many challenges involved in human missions to Mars.

Tamara gets a taste of what it’s like to be an astronaut launching into space as she takes flight in a jet fighter, experiencing high G forces and the feeling of weightlessness. Then meets a team of scientists working out ways to measure and mitigate the effects of micro-gravity on the body.

In Far North Queensland, one of the longest continuous lava flows from a single volcano that erupted 190,000 years ago may provide answers for human shelter on Mars. Escaping the heat of the day, Tamara joins the Ewamian Rangers on country to explore the lava tubes with astro-geologist, Dr David Flannery.

Artificial intelligence has long held promise to perform tasks humans can’t or won’t do. Given the hostile conditions on Mars, robots should be perfect for maintenance, reconnaissance and repair – leaving more time for human exploration and discovery.

Tamara joins the CSIRO team in Brisbane as they put ‘Kitten’ and ‘Rat’ to the ultimate test of searching and locating a human survivor.

Catalyst: Mars: Our Second Home? Part 1 airs Tuesday 23 February 8.30pm on ABC and iview



  1. An interesting show last night, but I’m curious about all the fuss about walking on Mars in its lower gravity – surely its gravity is significantly higher that the Moon and no one seemed to have to train to walk on the Moon in the same way as it was suggested re Mars?
