Sky Eye: Russian Hubble 1,000 times sharper - Hahaha!!!!

This will be the first radio-telescope that Russia has put into space in more than 25 years.

Whaaaaaath????
Hubble is not a radio telescope?

Did you notice the date on that piece?

Even on July 18, 2011, the basic laws of optics were known.

Hubble's mirror is 2.4 metres in diameter, and it _is_ diffraction-limited, now
that the corrective optics are installed.

The Russian telescope is 10 metres in diameter. This would make it over four
times sharper, if it sensed ultraviolet light, like the Hubble. Since, instead,
it is a radio telescope, it could not match Hubble's resolution.

It was destined to be one remote node of the global VLBI network but sat
at variable multiples of the Earth's radius. It will achieve the sort of
resolution they talk about on very bright very compact radio sources in
combination with the Earth's network of big dishes. Assuming that is
that they can determine its orbit to the required precision.

Wiki has a little bit about what it was intended to do - my guess is
that it fell well short of expectations.

It has had various annoyances and teething problems.
The U-V coverage it provides is rather eccentric as is its orbit.

Sample recent paper using it published in A&A last year.

People who know crap about telescopes, it's all the same! LOL!

The crap of VLBI and the useless attempt to detach 24 hour timekeeping from the Lat/Long system (whatever happened to that contrived fuss !) obscures that the planet has two surface rotations using our parent central star as a reference.

Calling people silly is unhelpful but then again it is extremely inconvenient for me to continuously demonstrate how timekeeping evolved thereby allowing the Polar day/night cycle and its rotational cause to emerge.

These unfortunate empiricists have loaded the North and South Poles with so many meaningless motions that they can't handle the action of the South Pole presently as it traverses the fully illuminated side of the Earth from September to next March before the central Sun turns out of sight. The Polar motion/rotation turns parallel to the orbital plane and where this surface rotation combines with daily rotation we get the seasons and variations in the natural noon cycle.

If I knew a way to stop engineers from making nuisances of themselves I would pursue that avenue but seemingly they are far too impressed by their equipment, including VLBI, and not enough on the astronomical heritage which stretches back to remote antiquity.

Most people gladly go out each day to do their best for their families,
communities, country or even humanity but not here. It is not that I do not understand it but I do - a foolish mistake made centuries ago that ran unchecked and expanded on by theorists.
