Unfortunately, by the time they build it, the sky will be crowded with noisy mini satellites that make radioastronomy difficult. Maybe later in the century they'll build something similar on the dark side of the moon. |

Unfortunately, by the time they build it, the sky will be crowded with noisy mini satellites that make radioastronomy difficult. There is already interference from the satellites already up there, especially so for those in geosynchronous orbit that are in continuous operation at the same points around that one plane. Hence by international agreement, (supposedly) the frequencies significant for astronomy are 'off limits' and are protected to be quiet. However, there is always the problem of poor design or compromised design... For the newly increasing swarms of internet satellites (StarLink, OneWeb, Amazon whatever, Iridium, Inmarsat, multiple GNSS,) there is supposedly some cooperation with astronomers to minimize interference. Note that we operate microwave ovens (very high power radios!) and other widely used radio systems in the "water hole" range of frequencies... Hence the need for remote radio quiet areas for radio telescopes. Note the restrictions for the electronic gadgets for anyone living near the Greenbank radio telescope for example. Maybe later in the century they'll build something similar on the dark side of the moon. The far side of the moon is a very difficult environment. A swarm of expendable satellites at a Lagrange point operating as a phased array could be a better bet. Or as we are doing at present, developing phased arrays of telescopes across the width of our entire earth (eg Merlin, SKA,) and earthly orbit (eg Event Horizon). Keep searchin'!

That gets a mention in this article about the newly agreed SKA: Square Kilometre Array Observatory has a council now, so building super-sensitive €1.3bn telescope is next on agenda wrote: The long-awaited Square Kilometre Array Observatory (SKAO) has continued its march to reality... And we thought the unwanted radar reflections hitting Arecibo from the one local airport were ' badly distracting'...

The latest update. UK is to build 'brain' of world's biggest radio telescope. The UK will build the 'brain' of the world's largest radio telescope, which is set to explore the evolution of the early Universe when it becomes operational by the end of the decade.Cheers. |

Our part of the SKA has recently been open to the press for a very short period and I've been watching the science/weather sections of our national broadcaster morning show coming from there live this morning. ‘Are we alone in the universe?’: work begins in Western Australia on world’s most powerful radio telescopes. Cheers. |

More on what I was watching this morning. Square Kilometre Array Telescope construction begins in West Australian outback. Cheers. |

Finally work begins. 'Frenetically busy' start to work on site for Square Kilometre Array in WA's outback Murchison. After decades of careful planning, an enormous $3 billion window into the origins of the known universe is taking shape on a remote sheep station in outback Western Australia.Cheers. |

Just another update on all those X-mas trees that are going up in our backyard way out west and a bit of the history behind it all. Australia's SKA-Low telescope is being built in the outback, in part to answer if we are alone in the universe. Cheers. |
