Talk:List of space telescopes

Solar telescope
The lead paragraph says that the list excludes solar telescope and redirects to List of Solar System probes, but that page also excludes Earth-orbiting solar telescopes. I think they should be included here. --Fukumoto (talk) 12:25, 15 March 2008 (UTC)
 * I'm inclined to set up a new page, covering all sun-related telescopes/probes, rather than including them here. This page is already rather long... Mike Peel (talk) 13:16, 15 March 2008 (UTC)
 * Not nearly good enough. A list of space telescopes looking at the Sun is completely missing from Wikipedia. They're are missing from here, they are missing from "List of solar telescopes", and the collection on "List of Solar System probes#Solar probes" contains non-telescopes like the Pioneer probes and is missing solar space observatories such as Hinode and SDO among others. By the way, the "List of space telescopes" is also missing all three OAO space telescopes, see "Orbiting Astronomical Observatory". Mollwollfumble (talk) 20:19, 13 September 2015 (UTC)

Abbreviations
I think it will look less clutterd if abbreviations are used primarily, e.g. ASCA instead of Advanced Satellite for Cosmology and Astrophysics (ASCA). --Fukumoto (talk) 03:06, 18 March 2008 (UTC)
 * Perhaps, but the name tends to provide a nice summary of what the telescope does (or is more recognisable, e.g. Hubble Space Telescope compared with HST). Plus, astronomy suffers from a case of TMA (Too Many Acronyms), which I don't want this article to fall prey to... Mike Peel (talk) 10:20, 28 August 2008 (UTC)

Ref(s)
Something is wrong with the 153 and 154 Ref(s). Can someone fix this? Galoubet (talk) 17:53, 26 September 2008 (UTC)

Height of Earth orbits
The introduction says "When the telescope is in Earth orbit, then two values for its height are given. These are respectively the periapsis and apoapsis of the initial orbit, i.e. the minimum and maximum distances between the telescope and the center of Earth's mass, in kilometers." However, all of the distances listed in the tables appear to be the altitudes of the periapsis and apoapsis, which differ from the periapsis and apoapsis by the radius of the Earth. I would fix the introduction myself but my computer doesn't edit Wikipedia well. 68.97.56.173 (talk) 15:11, 18 December 2009 (UTC)


 * Check out the new wording? It still seems a bit unwieldy.  Ideas?-  Sinneed  16:45, 18 December 2009 (UTC)


 * Reworded. Hopefully now correct and clearer. Rod57 (talk) 14:06, 12 February 2011 (UTC)

Sortable date columns
The sortable date columns eg launch date, don't work as many dates have been entered as day-month-year. Dates need to be editted eg to year-month#-date or something else that will sort correctly. Rod57 (talk) 13:26, 12 February 2011 (UTC)

why was astrosat removed?
i have added it again.plz dont remove it. 122.161.32.137 (talk) 09:15, 14 July 2012 (UTC)
 * It got moved to List of proposed space observatories. Fotaun (talk) 18:47, 26 November 2012 (UTC)

why no DSCOVR?
Should the NOAA's DSCOVR satellite be added here? I don't really know how it should fit into this list, as it images from ultraviolet to near infra-red, but it also measures total radiation, solar winds & other charged particles, and magnetic fields. - Nov 19 2016 2:30PM EST — Preceding unsigned comment added by 142.68.110.254 (talk) 19:33, 19 November 2016 (UTC)

Suggested merge with List of proposed space observatories
It might make maintenance easier ? But which is the preferred term (telescope seems to imply image forming which observatory does not) ? - Rod57 (talk) 19:02, 15 January 2018 (UTC)
 * I am surprised the merger has not taken place since 2017. Massive duplication. By the way, the article List of proposed space observatories should also be tagged for the move proposal. Rowan Forest (talk) 22:02, 2 November 2018 (UTC)

Complete full non-stop list
I am suggesting we make this one non-stop list instead of grouping them individually by frequency ranges: gamma ray, x-ray, ultraviolet, visible, infrared, microwave and radio. What if someone wants to querry the full number of still operating space telescopes? What if someone wants to read the full list with regards to earliest launch dates? What if someone wants to read the full list of locations either farthest or closest? Merging these charts still makes capable of querry of frequency ranges.--Wyn.junior (talk) 18:57, 8 February 2019 (UTC)

Notability for a telescope to appear on this page
Should this page aim to list all space telescopes, or only notable ones? I ask because the DeMi cubesat is currently in space, and has an onboard space telescope, though it's just a cubesat so the aperture can't be bigger than 10cm. Is it too small to list here, or should it be added? — Preceding unsigned comment added by Openatheclose (talk • contribs) 14:19, 5 September 2020 (UTC)
 * The DeMi cubesat has enough journal and news articles that (I believe) it can satisfy WP:GNG and be a separate WP article. I don't see any restrictions listed on space telescope criteria, so (probably) it can be listed here since it is notable. Praemonitus (talk) 01:13, 27 September 2023 (UTC)

To Be Launched
Whilst the past and currently operational space telescopes are grouped by major frequency ranges the 'To be launched' table is currently all lumped together. It also has, following the format of the other tables, a 'Terminated' column. Since they haven't been launched yet this seems kind of superfluous. What would people think about deleting it and replacing it with a column stating the frequency range e.g. Gamma ray, X-Ray, Ultraviolet etc. of the satellites instead?

Weber's Gravity Wave Detector on Apollo 17
Should this be mentioned? It few on Apollo 17 and was deployed on the moon. It did not work due to a fabrication error. The following is from the Wikipedia article Joseph Weber.

He developed the first gravitational wave detectors (Weber bars) in the 1960s, and began publishing papers with evidence that he had detected these waves. In 1972, he sent a gravitational wave detection apparatus to the moon (the "Lunar Surface Gravimeter," part of the Apollo Lunar Surface Experiments Package) on the Apollo 17 lunar mission. AGNrule (talk) 21:02, 26 July 2023 (UTC)


 * I added the entry for the Apollo 17 Lunar Surface Gravimeter.
 * Some background; I work in a related field, know of the experiment, and have talked to one of the crew members who tried to deploy it. LSG is underplayed today for a reason that may be obvious.
 * Joe Weber, the PI, had a reputation as a gravitational wave detection expert, and NASA HQ agreed that searching for gravitational waves on the moon was worth a try. There was great anticipation since, before the flight, this experiment was seen as the best opportunity for Project Apollo to earn a Nobel Prize.
 * When the instrument was deployed, the crew found that the balance beam could not be balanced. A weight in the detector was so heavy that the springs they could adjust were not strong enough to bring the beam into balance. An investigation after the flight showed that the design did not consider the fact that the lunar gravity is a sixth of that of the Earth's.
 * Recent LIGO detections show that the LSG would not have cosmic detected gravitational waves. AGNrule (talk) 23:31, 15 August 2023 (UTC)

International Lunar Observatory
I boldly added ILO-X as evidence suggests the IM-1 mission successfully delivered it to the lunar surface. I believe it to be a visible light telescope; perhaps the first by a non-government entity? (— 𝐬𝐝𝐒𝐝𝐬 — - talk) 23:39, 24 February 2024 (UTC)
