message: There seems to be an undue prominence placed on the NASA great observatories, while other comparable telescopes (e.g. INTEGRAL, XMM-Newton, WMAP, ... ) are not even mentioned in the "other notable space observatories" section which seems to be a rundown of only all the decommissioned ones.

message: First section claims that Hubble was the first space observatory (in 1990), but the OAO page refers to those satellites, launched as early as 1966, as space observatories and space telescopes.  Hubble's own page starts with the mention that Hubble was not the first space telescope.  Is this an error? ReverendTed 18:39, 20 March 2016 (UTC)

message: Hello wikipedians,
I have looked around a bit in the space-section of wikipedia, and one thing that bothers me is that there seems to be no clear definition of what is and what is not a "space telescope". This is a little bit related to the above question about Hubble being the first space telescope, since of course to decide what was the first "space telescope" one needs to define what a "space telescope" is. I think this issue of the definition would be best addressed in this article of wikipedia. I would like to suggest the definition to be something like:
A "space telescope" is a spacecraft that is:
1. Located in space (you cannot have a space telescope that is not in space I think; space is defined as the 100km limit in altitude so balloon-borne telescopes are not space telescopes)
2. Used for observation of astronomical objects outside Earth's atmosphere (so that various Earth-observing satellites, even though they usually have a telescope  as a structural component, are not space telescopes)
3. Observes electromagnetic radiation in any of its forms (gamma radiation - X-ray - UV - light - infrared - millimeter - radio); for example solar wind observing particle detectors are not space telescopes
4. Is not a space probe, i.e. does not travel to its object of study (so various planetary probes etc., even though having a telescope as a structural element are not space telescopes)
5. (maybe) Produces images or something similar (not just a number as an observation result like many instruments do)
What do you think, could the above five criteria form the definition of "space telescope"?  — Preceding unsigned comment added by 128.214.79.42 (talk) 05:48, 10 September 2019 (UTC)

message: I think it’s the CHANDRA space telescope labeled as “Key” in the diagram, not spitzer, as the image is captioned. Can someone double check me on this? Bray (talk) 04:03, 2 March 2022 (UTC)
replies: text: from top to bottom its actually the spitzer, hubble, XMM. the caption is correct but the picture labels are not. - Sudazima 2001:1C01:2D00:AA00:3D4D:4E9A:11A6:AA75 (talk) 18:18, 15 December 2023 (UTC)
