Talk:CORONA (satellite)

message: Under the CORONA launch listings, an erroneous note is listed: "The imagery from this mission was used by NASA meteorologist Captain Houston as the basis for the rerouting of Apollo 11's splashdown site." CORONA did not (directly) provide meteorological imagery; this was left to Program 417 (DMSP). Since the source is an opinion piece, here is the NRO history article correctly referencing DMSP instead of CORONA: http://www.nrojr.gov/teamrecon/res_ba/articles/Art%201%20Rescue%20of%20Apollo%2011%20Rev4.pdf TDRSS (talk) 16:13, 22 December 2017 (UTC)
thread_title:  Misunderstood Reference to Program 417 

message: The phrases Corona program and Corona project should redirect to the article. These would be most convenient to people who want to find or hyperlink to this article, and after all, this series of satellites were a program or a project with dozens of launches, just like the Explorer project, the Tiros program, the Transit program, the Sputnik program, the Mariner program, the Viking program, the Voyager program, the Mercury project, the Gemini project, the Apollo program, Apollo project, the Vostok program, the Soyuz program. and so forth.98.67.97.108 (talk) 20:48, 12 August 2010 (UTC)

message: I recalled watching shows on either TLC or Discovery that mentioned the CORONA buckets have salt plugs that would dissolve after 24 hours being in the water, thereby sinking it and preventing it from falling it into the wrong hands. If this is true, it allows the buckets to be recovered in the water if they've missed using the mid-air recovery. Calyth 15:12, 8 August 2005 (UTC)
replies: text: True.  This is mentioned in Peebles' Corona book as well as maybe Day's.  A photo exists with a sample recovery.  The photo used in various texts is just off the coast of Santa Barbara (those those geo-knowledgable of the rock formations in the background and the firms (3) who had offices there). 143.232.210.38 (talk) 23:49, 17 December 2007 (UTC)

message: The photo caption for the constantly rotating camera lens system (both J-1 and J-3) was incorrectly listed as "reciprocating." One of the means of improving the resolution of the camera system was to reduce vibration. The upgrade from the earlier reciprocating camera lens system was beneficial in this regard.

message: What happened once they dropped the film, did the satellite remain in orbit? 82.46.109.233 (talk) 14:26, 18 November 2011 (UTC)
replies: text: They surely decayed and reentered the atmosphere.  Lifetime at those low altitudes is not long due to atmospheric drag but it seems to depend on orbit, size of vehicle, and other things.  See http://www.ips.gov.au/Category/Educational/Space%20Weather/Space%20Weather%20Effects/SatelliteOrbitalDecayCalculations.pdf for details. Mnp (talk) 00:19, 12 November 2012 (UTC)

message: If the 'Launches' tables are sorted by date, they do not arrange themselves in the right order. I get the following when I click to a chronological order:
Mission No.	Cover Name	Launch Date	NSSDC ID No.	Alt. Name	Camera	Notes
R&D	Discoverer 3	03 Jun 1959	DISCOV3	1959-F02	none	Failed to orbit
9004	Discoverer 7	07 Nov 1959	1959-010A	1959 KAP	KH-1	Mission failed. Failed to achieve orbit.[citation needed]
R&D	Discoverer 2	13 Apr 1959	1959-003A	1959 GAM	none	First three-axis stabilized satellite; capsule recovery failed
9002	Discoverer 5	13 Aug 1959	1959-005A	1959 EPS 1	KH-1	Mission failed. Power supply failure. No recovery.
9003	Discoverer 6	19 Aug 1959	1959-006A	1959 ZET	KH-1	Mission failed. Retro rockets malfunctioned negating recovery.
9005	Discoverer 8	20 Nov 1959	1959-011A	1959 LAM	KH-1	Mission failed. Eccentric orbit negating recovery.
R&D	Discoverer	21 Jan 1959	1959-E01	1959-E01	none	Mission Failed. Failed to achieve orbit
9001	Discoverer 4	25 Jun 1959	DISC4	1959-U01	KH-1	Mission failed. Failed to achieve orbit.
R&D	Discoverer 1	28 Feb 1959	1959-002A	1959 BET	none	First object in polar orbit
9006	Discoverer 9	04 Feb 1960	DiSC9	1960-F01	KH-1	Mission failed. Failed to achieve orbit.
And so on. I appreciate the launches are in the right order on first load, but being wrong when a user clicks on the date option means that the table becomes worthless without a reload (presuming the user notices it) if they try sorting by any other option.  — Preceding unsigned comment added by Justicia311 (talk • contribs) 23:12, 26 March 2012 (UTC)

message: :"The name of this program is sometimes seen in pre-ASCII all caps as "CORONA", but in mixed caps, its actual name "Corona" was a codeword, not an acronym."
That is a contender for the most muddled sentence in the entire Wikipedia. All caps but in mixed caps? The name was Corona in mixed case, but not an acronym? And why is ASCII mentioned? 91.10.8.184 (talk) 20:49, 2 March 2019 (UTC)

message: The picture of the lens in the article shows a lens manufactured by Canon, "Made in Japan". https://en.wikipedia.org/wiki/File:Corona_Satellite_Index_Camera_Lens.jpg
Canon is not mentioned anywhere, the article tells us "The cameras were manufactured by the Itek Corporation.[13]", referencing to https://en.wikipedia.org/wiki/Itek , which in turn also does not mention any involvement with the Japanese lens manufacturer Canon. 
Either the picture is not correct, or there is vital information that is missing or is incorrect in the text and references regarding the lens used.  — Preceding unsigned comment added by 92.220.44.63 (talk) 14:55, 13 September 2020 (UTC)
