The discussion centers on the feasibility of constructing a telescope with an aperture size approaching half the Solar System by utilizing Earth-Sun Lagrange Points (L1, L2, L3, and L4) and employing interferometry techniques. Key challenges include the need for numerous dishes to achieve high resolution, the difficulty of combining signals from multiple telescopes with precision, and the limitations of current technology in maintaining accurate positioning and timekeeping. While some participants suggested that AI could mitigate these issues, others firmly rejected this notion, emphasizing that AI does not enhance the fundamental technological limitations of astronomical observation.
PREREQUISITESAstronomers, astrophysicists, aerospace engineers, and anyone interested in the future of large-scale astronomical observations and the integration of AI in space science.
The glaring issues can maybe removed by AI to some extent.LastScattered1090 said:Lagrange Points are specific to a two-body gravitationally-interacting system. So I guess the question is: which Lagrange points are you referring to? If you are thinking of Earth-Sun Lagrange points, then yeah, maybe you could start to build up through interferometry an aperture approaching the AU scale (not the scale of the entire solar system). There are some glaring problems I can think of:
- You need to actually fill in the space with dishes/apertures to get good resolution. The more inteferometry baselines (pairwise separations of dishes) you have, the better you will do. But you're not going to get much advantage with only handful of baselines.
- You need to combine signals from the telescopes very precisely in order to do interferometry: either in real time, or after the fact using precise phase information about the EM waves measured by each telescope. Precisely measuring the phase information at optical (UV/vis/IR) wavelengths (compared to radio) is very challenging due to the short wavelength. Combine that with the fact that your spacecraft move around (changing your baselines continuously) and it's not obvious to me that we have precise enough positioning/stationkeeping and timekeeping ability to pull this off.
I don't see how. AI is not a more stable clock, nor is it higher speed electronics. AI does not reduce positional drift from micrometeorite impacts, nor does it give you extra sensors. What did you have in mind?Mukhtar said:The glaring issues can maybe removed by AI to some extent.
Actually I was trying to mean the prediction of positions of planets and stars with their distance differences taken into account along with the size of stars and planets(if real image cannot be captured of such bodies then can be prepared through AI with all the information)Ibix said:I don't see how.

This is way off topic for both this thread and this forum. Your original question has been answered. Thread closed.Mukhtar said:The glaring issues can maybe removed by AI to some extent.
