As the hundred posts or so in the thread discuss, there are many problems with a lunar scope, but I don't think communication with the dark side is an intractable one.
as Steamking said, it isn't worth the cost or effort ... it can all be done from earth orbit for a tiny fraction of the costAs the hundred posts or so in the thread discuss, there are many problems with a lunar scope, but I don't think communication with the dark side is an intractable one.
I don't think any of the problems are intractable. This is a question of practicality, not possibility. You plop a Surveyor on the moon, have it wait until night, take a few shots of the sky, and send 'em back when you're in daylight again. But that surely would not be worth the effort.I don't think communication with the dark side is an intractable one.
Right, as I indicated, lunar dark side surface to L2, relay to L4 and relay to earth. I'm guessing this has long been the proposed communication solution for any kind of long term installation on the dark side.Earth/Moon L2 is still completely shielded from radiation from Earth. It is also easy to relay signals via a satellite at L4/L5 or in various Moon orbits.
Ok so if I gave you the choice of a telescope in orbit on a remote controlled satellite.The problem with a lunar telescope is not one of feasibility, it is one of motivation. Does the potential benefit justify the effort? At this point that may be dubious, but, we never learn the benefits of exploration without accepting some level of risk. I like the idea of putting aside political squabbles in exchange for acquiring knowledge that may benefit all of humanity. We did it before by putting a man on the moon. We can do it again by continuing that mission in a cooperative sense. I believe most earthlings would overwhelmingly favor that option over enhancing our ability to destroy life on earth
If you're goal is to deliver a written message across the ocean why sail there in a raft if you could just send an email?The dusty surface of the moon which has no wind to waft the dust around? It's not about prestige, its about mastering the technological challenges needed to pull off the job. Your argument makes about as much sense as - why risk sailing across the sea when you can just carve a message on a coconut and toss it into the outgoing tide?
A satellite in a circular orbit 400,000km from Earth is:A paper just appeared......The advantages of a lunar based telescope are discussed here; http://phys.scichina.com:8083/sciGe/fileup/PDF/11yg0558.pdf, echoing many of the sentiments noted in this thread. Obviously, China found sufficient merit [and funding] for such a project.
As mentioned in the paper:So...what are the advantages of a lunar scope as compared to a satellite scope?
With respect to stability, what's the typical pointing stability of a space based instrument as compared one on a body? The paper references 10 day observations.3) The temperature in the permanent shadow regions (PSRs) at both poles of the Moon could be as low as 30 K . PSRs are therefore rare ideal conditions for infrared observations.
