Professional radio astronomy - SKA et al.

eg: Scientists analyze 76 million radio telescope images, find Starlink satellite interference 'where no signals are supposed to be present' (2025)

~ https://www.space.com/astronomy/scientists-analyze-76-millio...

and the topic is Starlink (and other sat constellations) and their impact on the sky (visible and non visible).

Yes, they do post about it.

Yes they do talk about working to avoid causing interference.

That's been ongoing since before the first Starlink went up and has been ongoing as later generations haven't improved.

Second-Generation Starlink Satellites Leak 30 Times More Radio Interference, Threatening Astronomical Observations https://www.astron.nl/starlink-satellites/

  Observations with the LOFAR (Low Frequency Array) radio telescope last year showed that first generation Starlink satellites emit unintended radio waves that can hinder astronomical observations. New observations with the LOFAR radio telescope, the biggest radio telescope on Earth observing at low frequencies, have shown that the second generation ’V2-mini’ Starlink satellites emit up to 32 times brighter unintended radio waves than satellites from the previous generation, potentially blinding radio telescopes and crippling vital research of the Universe.
Still, at least they are talking about maybe doing something. Eventually. Perhaps.

It's old news that they leak, and old news that F-all gets done about it.

Back to you.

You forgot about the radio spectrum pollution which affects the night and day sky right now .. and for the foreseeable future given the lack of progress in addressing that leakage.

Sucks for regular astronomy then, where long exposures are the norm.

Equally sucks for radio astronomy where the bloody things leak into spectrums they (Starlink) pinky promised to keep clean. And successive generations have worsened the problem, again despite promises to improve.

Kind of moot given Japan surrendered.

Had they not, the carpet bombings would have continued - not just the fire bombing of Tokyo, another 71 cities had also been bombed flat. With H&N that made a total of 74 cities down and a list of targets for future bombing still ready to work through.

FWiW the HE+incendiaries bombings used more planes but were cheaper overall than (at that time) atomic weapons - and (at that time) caused much the same amount of damage, injury, and death.

Just cancer might be the equivalence.

Smoking itself cause damage and disease that isn't limited to just cancer though.

Thanks for the response, it's been awhile since I used an ambulance. I've got to say, I was willing to believe, what with free Qld buses and all that jazz, but alas like WA it's "qualified":

  There's no cost for ambulance treatment and transport for Queensland residents. This includes treatment and transport that takes place in other parts of Australia.
and

  If you don’t live in Queensland, you’ll be charged for ambulance treatment and transport. If you have ambulance cover in another state it may cover the cost for you.

> the Gregorian date with year 1 as the (wrongly dated?) birthyear of Jesus Christ is the standard for most domains in international communication.

Save for those that care about missing days and months.

As long as cross country events prior to ~1756 aren't being discussed, things get messy and non uniform fast.

Also, there are Gregorian adjacent calendar variants with a Year 0

> some future astronomer will be translating timestamps between GPS time and UTC, entirely aware of leap seconds and atomic time and whatnot, just to make sense of 21st century observations.

A future where the spin of the earth still isn't a uniform metronome - a future with the same issue that exists today (and last century).

> their woes will pale in comparison with those of the poor soul who has to add support

Much of this support has _already_ been added - SKA data networks, for example, have to account for timing issue caused by receivers on one side of planet turning toward a source Vs those on the other side turning away - and reconcile that with past data from the other side of the orbit when the planet was moving toward Vs now when it moves away.

Yeah, nah - that "we" doesn't cover all the other calendars also in use.

  The Julian period is a chronological interval of 7980 years, derived from three multi-year cycles: the indiction, solar, and lunar cycles. The last year that was simultaneously the beginning of all three cycles was 4713 BC (−4712), so that is year 1 of the current Julian period, making AD 2026 year 6739 of that Period.

Well, yeah, that to - although TBH it's never been an issue in my line of work which started with (LORAN actually, and then moved to..) off book reverse engineering of the OG NavStar format. To this day it's still "raw" GPS packets that are logged - and later post processed for greater accuracy (and often blended with a local area fixed position base stations "corrections" for GPS fix wobble).

There's a lot of fiddly pedantic stuff that goes with scientific data recording, timekeeping is but one domain of possible issues.

> Australia is also going bankrupt just slightly faster than the United States.

Dunno about that, there be weeds. Not to mention the US clown car demolition derby is still in office.

Still, the coronavirus pandemic and associated policy responses led to the largest deterioration in the Australian Commonwealth Government’s fiscal position since the Second World War. That was 2021.

The forecast national net debt has looked pretty shitty since then, but the arc has been one of improvement - last years 2025-26 National Fiscal Outlook has been claimed to be overly grim by the most recent KPMG assessment of the 2026–27 AU Budget and backs the estimates that the Federal Government net debt servicing will return to pre COVID levels by 2029-30.

Yeah, it's f-obvious it takes longer for a plane to cross 600km than it takes an ambulance to cross a Sydney suburb.

Any other insights?

W.Australia has a land area three time that of Texas with the bulk of the 2.9 million in population clustered about the capital city Perth.

In the rest of the state there are volunteer Ambulance services subsidised by state and federal government and a fleet of Royal Flying Doctor air ambulances.

RFD(WA) comes in at ~ $80 million AUD / annum in state support (for better or worse - https://www.abc.net.au/news/2024-07-24/rural-gp-slams-royal-... )

They assert to have a "value" to the state of $4.1 billion AUD over 30 years - https://www.flyingdoctor.org.au/wa/

  Every day, the Royal Flying Doctor Service in Western Australia retrieves 29 people.

St. John's Ambulance service in Australia is a hybrid of core paid positions and volunteers (varying by region and demand).

In rural Australia most of the fire, ambulance, and emergency response service are volunteer manned and (locally) run, with federal and state assistance for equipment and costs.

Costwise AU Ambulances are either free (if you're a St. John's member - cheap per annum OR if covered by private / work insurance) or (a decade out of date number) a flat fee of $500.

It's a hassle for anybody doing or recording "physics" as they cannot log against UTC (which may or may not have an added second or removed second in some interval if it happens to overlap the adjustment zone).

Those things that really do rely on actual "elapsed time" rather than the difference between two recorded "book times".

Does this happen? Yes, a few times in my career in geophysical exploration - it's why multiple bits of gear are synced to a reference "real clock" which gets logged against the raw GPS epoch time (real time since Sunday last week(?)) and processed "UTC" time (some variation of it).
