Orphan section at the top
There were recently pages on both "space observatory" and "space telescope." I merged the two. Should the result be placed here, or at space telescope? --zandperl 23:13, 2 Mar 2004 (UTC)

I wonder if perhaps "space telescope" might be more often searched for? By the way, the article needs links to Ginga, Asca, IRTS, ASTRO-E2 (Suzaku), Exosat, Cos-B, Integral, Gaia, Darwin, FIRM, perhaps COBE, WMAP and Planck, possibly some early Japanese missions (Tenma, Hinotori), and probably a few others. It's on my list of things to do but if anyone else would like to volunteer it would be very welcome.--Serjeant 10:18, 21 December 2005 (UTC)

numerous major observatories missing
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.

Instead of making the list grow, I would suggest getting rid of it entirely. It's redundant with List of space telescopes. The article needs to be fleshed out, not cluttered with a list. I'll be bold and dispose of it eventually if nobody protests. Equendil Talk 18:44, 29 April 2009 (UTC)
 * Actually I'll just do it now, List of space telescopes is a featured list, I can't imagine any good reason to keep a list here. Equendil Talk 18:48, 29 April 2009 (UTC)

Calling Alan Parsons
So when was the space telescope first proposed, & by whom...? TREKphiler  hit me ♠  09:10, 20 November 2009 (UTC)

HST First Space Observatory?
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? Reverend Ted 18:39, 20 March 2016 (UTC)
 * ✅ Indeed that was plain wrong. I rewrote the lead paragraph with accurate history of the earliest operational space telescopes. — JFG talk 12:25, 28 May 2016 (UTC)

Definition of space telescope
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)

Diagram doesn’t show spitzer
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)


 * 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)

On the lunar surface
What's the plan for covering telescopes on the surface of the Moon? International Lunar Observatory has ILO-X there now.... (— 𝐬𝐝𝐒𝐝𝐬 — - talk) 03:13, 26 February 2024 (UTC)
