Peaceful Nuclear Explosions and Other Bad Ideas
Posted on
11th Dec 2024
Nuke Mars. You’ve probably heard about this, or maybe you have the t-shirt. The idea is simple. Mars has a cold, thin atmosphere that doesn’t support liquid water on its surface. You might think this is a non-problem not looking for a solution, but there is a segment of society intent on moving to M...
Space Dirt From Bennu
Posted on
16th Feb 2024
Osiris-Rex travelled around 6-billion km to get to asteroid Bennu, pick up some samples, and get them back to Earth. Now, you won’t often see people more excited by dirt, but this is dirt from another planet – which as a consequence of being other-worldly is rather rare on Earth. And it might jus...
Shadow Games: Exmouth Gets Solar Eclipse
Posted on
5th May 2023
The hybrid solar eclipse in Exmouth a couple of weeks ago was a pretty rare event, but to the surprise of no-one it was predicted with more-or-less perfect accuracy (cause, science). But it wasn’t always that way – actually, it was only a few hundred years ago that Halley (the comet guy) made the fi...

The post office got a bad rap during COVID, but I’m not sure too many people want their mail delivered by rocket.

In case you’ve been living under a rock lately and missed the big announcement, Australia recently committed to ‘never conduct destructive, direct-ascent anti-satellite missile testing’.
Why would we do that? Well, for starters New Zealand have already committed and we don’t want to look like we a...
Armageddon Averted: NASA Versus Dimorphos
Posted on
20th Oct 2022
DART is the mission based on the Hollywood blockbuster Armageddon. You know, the movie where the oil drillers are trained to go to space because there couldn’t possibly be an astronaut capable of being trained to be an oil driller. Anyway, if you think Michael Bay’s explosions are over the top, well...
Dinner on Mars
Posted on
5th Mar 2021
We have rovers on Mars. Perseverance (or Percy, if you're on nickname terms) landed there just a few weeks ago to join Curiosity. And don't forget about Spirit and Opportunity (or Oppy, if you like) which also spent years traversing the Martian wastelands. Then just yesterday we saw the...
Gargantuan Black Hole Bigger Than Thought
Posted on
5th Mar 2021
Here's a brief history on our understanding of black holes. In 1783 John Michell had a thought. Now that in itself was not unusual, as Michell was a philosopher, and someone whose thoughts were purportedly generations ahead of his contemporaries. What was unusual was that Michell began to think ab...
