Are we going to get trapped on earth by a swarm of colliding space debris?

I've been a little slow to pick up on this one, but there's a company in the US, Reflect Orbital, that is offering services based on having mirrors in space. Given that the company's previous name was Tons of Mirrors, it would seem that their aim is likely to be to imitate Elon Musk's Starlink by launching thousands of mirrors into low-earth orbit, and pointing them back at earth. One article reports that the company plans to have 4,000 satellites in orbit by 2030, with the eventual aim of launching a quarter of a million satellites.

On 27 January POTUS (the President Of The United States) signed an executive order to create an “Iron Dome” of defence against ballistic, hypersonic, cruise missiles and other advanced aerial attacks. This was renamed “Golden Dome for America” on 24 February. Surprisingly, the renaming isn't about POTUS' preference for golden things. Apparently “Iron Dome” is a registered trademark, owned by an Israeli defence firm.

Craig wrote a couple of weeks ago about a couple of strange ideas he was introduced to at a Matariki event he attended - the idea that Matariki's brightness can predict the future, and also an idea that the earth has apparently recently shifted on its axis by 20 degrees.

The Chinese launch vehicle - Long March 5B has been in the news over the past week. The rocket was launched at the end of last month to carry the living quarters of China's independent space station into orbit.

Disappointingly, despite the excitement, I'm sure many listeners will already have figured out what the rational explanation for this string of lights in the sky over Melbourne was: Elon Musk's Starlink, a company that is providing satellite based internet - with a few tens of thousands of satellites planned to be deployed over the next few years. There are valid questions about whether these devices are damaging to astronomy, and have the potential to clutter earth's orbit, but they're definitely not visiting aliens. If you are able to get out and see these satellites as they maneuver themselves into their operational orbits, I'd definitely recommend it. I saw them late last year, and it was an impressive sight - a real testament to modern technology.

Sometimes a programme really makes one think about how television defines what is important for us to know about.
