    @denysvlasenko1865 5 месяцев назад +1

    I actually don't get what a 50m single dish can do what ALMA can't. The conversation did not provide the numbers.
    Its total aperture is only a third of ALMA's fifty four 12m dishes, so SNR has to be lower.
    Its resolution is way below ALMA's in interferometer mode.
    What I heard is that it would have good SNR and resolution *while* having a large field-of-view (more than one square degree), IOW: it can be a survey telescope.
    Which is good, no question...
    until you consider what enormous PITA is it to build a 50 meter parabolic reflector to ~30um surface tolerance, and to KEEP that tolerance in a high desert conditions.
    Compared to this, 12m ALMA dishes are "extremely easy" because they are that much smaller.
    Notice how DSN is *getting rid* of its 64m antennae because they are too costly to maintain (they switch to arraying several 34m antennae because those are far cheaper, AND they can do two other things at once when do not need to be in array mode!). And _these_ 64m dishes are NOT at submillimeter tolerances, and are NOT in the high mountainous desert where everything costs at least 3x more - and yet, they are too costly.
    There are many other things that can be done at ALMA.
    Adding outrigger dishes to increase resolution of the interferometer - incremental work, every new dish just adds a bit more resolution, no new gigantic costly dish designs.
    Adding separate correlators so that array can be split into several subarrays, this can allow to run survey, or even several separate concurrent surveys (!) with existing dishes.
    The usual upgrades to receivers, correlator, electronics.

  • @BabyMakR
    @BabyMakR 5 месяцев назад +2

    Out of curiosity, if a friendly billionaire was to come along and say they want to upgrade all the dishes at ALMA to 20M, how much would that cost and what would the sensitivity and resolution increases be?

    • @denysvlasenko1865
      @denysvlasenko1865 5 месяцев назад +1

      Buy more 12m dishes instead - no need to redesign anything. Interferometer resolution depends on the number and distances between them. ALMA site has plenty of space around it to add more outlying dishes.

    What would it cost to build an AU-radius spherical telescope by sprinkling cubesats with cameras/antennas, using solar panels as make-shift solar sails for maneuvering, on a constellation of close-to-polar orbit around the Sun, Startlink/GPS style, using mesh networking so they don't have to be strong enough to reach Earth, just the nearest cubsesat in the constellation, and relay their data till reaching Earth? And what kind of data could we expect to get from something like that? If the cubesats were launched at the same rate as Starlink have been launched on average, how long until we could get the full sphere?

    • @RectalRooter
      @RectalRooter 5 месяцев назад

      I think your forgetting -- 1 reason these type of telescopes works -- Is because -- Once the antennas are in position they don't move. We know exactly where each antenna in placed. Imagine how difficult it would be to keep them from moving / wiggling around in Spaaaaaace
      Look up some videos aboot what it took to make the Earth size radio telescope ( the Event Horizon telescope ) to work - The very precise timestamps that allowed the each of the radio telescopes data to be synced up.

    • @denysvlasenko1865
