Discussion Overview

The discussion revolves around the capabilities of the Hubble Space Telescope, particularly in relation to its ability to capture images of the Apollo landing sites on the Moon. Participants explore the differences between telescopes and microscopes, the prioritization of Hubble's observational time, and the technical limitations of the telescope's resolution.

Discussion Character

  • Debate/contested
  • Technical explanation
  • Conceptual clarification

Main Points Raised

  • Some participants argue that the Hubble is over-subscribed and primarily used for high-priority research, making it unlikely to focus on the Apollo landing sites.
  • Others suggest that ground-based telescopes can also observe the remnants of the Apollo missions, questioning the necessity of using Hubble for this purpose.
  • There is a discussion about the resolution of telescopes, with one participant explaining that Hubble's resolution is dependent on its aperture and that it does not have variable magnification.
  • One participant points out the fundamental differences between telescopes and microscopes, emphasizing that telescopes focus on distant objects while microscopes focus on much closer ones.
  • Concerns are raised about the willingness of the person questioning Hubble's capabilities to accept scientific explanations, especially regarding NASA's credibility.

Areas of Agreement / Disagreement

Participants express differing views on the Hubble's capabilities and its prioritization for research. There is no consensus on whether Hubble should be used to capture images of the Apollo landing sites, and the discussion remains unresolved regarding the validity of the claims made by the individual questioning Hubble's worth.

Contextual Notes

Limitations include the dependence on the definitions of resolution and the specific capabilities of different telescopes. The discussion also highlights assumptions about the prioritization of research projects and the technical specifications of the Hubble telescope.

I know this guy, and he say the Hubble telescope is worthless and has never done anything because it cannot take clear pictures of the Apollo landing site. This because he think it was a hoax and he wants proof:rolleyes: .

He is currently not convinced of the reason Hubble cannot take such photos as explained on the official Hubble site. I have tried convincing him that Hubble is not worthless, I told him to look up the Deep Field Images and told him about the new moons around Pluto.

So does anyone have anything to comment about why the Hubble cannot just zoom in like a microscope and take these photos of the Apollo debris on the Moon?

Do you or him know how over-subscribed the Hubble is? Practically every second of its existence is being used for a research observation, and there are tons of people and institutions waiting in line to gain access to it. Call me crazy, but looking at the moon for the debris of the apollo landing is NOT a research project of any degree of priority, not especially when it costs THAT much.

Besides, why would one need the Hubble to verify this? You CAN see the remnants of the apollo missions from ground based telescope. So get this person to one of the larger telescopes, pay for access, and see for himself! What's the big deal of only using the Hubble, especially when the Hubble was meant to look at something else with such dim intensities.

All that aside, isn't it simply a matter of resolution?

The thing you and your friend need to understand is that the resolution of a telescope is dependent on it's aperature. Go to the astrophotography thread in astronomy and look at my pics of the planets, or look at a telescope advertisement and check for where it lists the resolution.

Also, afaik, the Hubble doesn't have variable magnification (though different instruments have different resolutions/fields of view) - so there is no "zooming". According to http://www.digibird.com/primerdir/primer0.htm" site, Hubble's resolution on the moon is about 50-100m. Have your friend Google the distance to the moon and the aperature of Hubble and verify that for himself.

I suspect, however, that your friend will not listen to reason on this subject. I mean - if NASA is taking the pictures, why would your friend believe NASA about this, but not the Apollo missions themselves?

edit: http://sm3a.gsfc.nasa.gov/messages/676.html" site goes through the calculation for him...

One more thing - there is a difference between a telescope and a microscope that should be obvious: a telescope is focusing on objects, essentially an infinite distance away (as far as the optics are concerned) and a microscope is focusing on objects any where from a couple of milimeters to a couple of centimeters way. The optics work differently.
