In 1999, an archived speech was discovered that had been written for US President Richard Nixon 30 years before in case a disaster on the Apollo 11 mission left the astronauts with no hope of recovery.

Thankfully, that speech never had to be given – but what if it had? What if some key component on the lunar lander had failed, stranding Neil Armstrong and Buzz Aldrin on the moon, to slowly run out of oxygen as the world watched in horror?

It’s a question asked by author David Dyer in his new novel, This Kingdom of Dust, which provides a fictionalised look at just such a scenario.

In this Space Connect podcast, he talks to Jake Nelson about NASA’s concerns with the Apollo program, how the world might have reacted, and whether the enthusiasm for space travel so prevalent in the 1960s can be recaptured.

In October, Scott Morrison was surprisingly unveiled as the new chairman of Space Centre Australia, the planned spaceport in Far North Queensland.

The move has the potential to hugely disrupt Australia’'s launch sector, which already has four spaceports scattered around the country.

Now, a few weeks later, the former prime minister joins Robert Dougherty in our studio in North Sydney.

The pair discuss the new government’s cuts to the space sector, whether the industry will recover, and how Australia can take advantage of its geographical advantages to become a leader in launch.

From 29 September to 25 November, Earth will have a new temporary ‘mini moon’.

Named 2024 PT5, the object is actually an asteroid from the Arjuna asteroid group that will be captured by Earth’s gravity for 57 days.

It’s so small and faint that it won’t be visible to the eye or even with small telescopes, but it will be visible to larger telescopes.

Astrophysicist Dr Laura Driessen, from the University of Sydney, talks through the history of mini moons and what the rare discovery means.
