Talk:Cosmos 1

message: The statement: "With increasing distance from the Sun, fewer photons collide per unit time and acceleration decreases even further." is true, but does not apply to Cosmos 1.  This only applies for a solar sail orbitting the Sun.  Since the craft remains in earth orbit the distance to the Sun will not change significantly.  Also, the acceleration due to sunlight is not constant for an Earth orbitting sail.  The craft spends some part of each orbit in the shadow of the Earth, it spends part of each orbit moving toward the Sun (during this time the sail is tilted "edge on" to prevent sunlight from slowing the spacecraft) and only for a portion of the orbit does the sunlight increase the energy of the orbit.  The accleration of the craft would then increase slightly each orbit but it would not be constant.  --Mu301 14:33, 22 Jun 2005 (UTC)
thread_title: Physics of Cosmos 1

message: I've never heard of any Dr. Darren Wogman in connection with solar sails, and I do not believe that such a person was ever involved in the development of the solar sail technology - the concept, the Mylar, the Cosmos 1 spacecraft, or anything. Indeed Google only returns one functioning hit on "Darren Wogman" and none on "Wogman, Darren."  Therefore, I've deleted the following from the story:
"using the pioneering technology from Dr. Darren Wogman."
Since Cosmos 1 is in the news, there are probably a lot of people visiting this article, so it's important that it be accurate.  I'd rather err on the side of caution and just take out the Wogman reference.  Is there anyone who would like to see it put back in?  -Centurion328 10:26, 22 Jun 2005 (UTC)

message: The Cosmos 1 mission homepage states:
The Cosmos 1 spacecraft will be shipped to the launch area in mid May. Until then we have put our countdown on hold. The actual launch date will be announced during the week of May 16.
Also, I made minor changes to the Cosmos 1 information in the solar sail article.

(Should I have moved it to photon instead ?)

message: Why is EDT being used in the article? It seems to have no relevance. PDT has little relevance either to the times for which it is listed. I think that the times in question should be converted to UTC, possibly with PDT in parenthesis. Any comments? --GW… 18:45, 28 January 2009 (UTC)

message: Can anyone explain why "Cosmos 1" is italicized in most places in this article?  If not, I shall remove all of the italics soon, since this does not appear to be a title that requires italics, such as book titles, ship names, and so forth. – Paine Ellsworth ( CLIMAX )  00:05, 7 May 2011 (UTC)

message: Could someone explain the strange use of phrasing in the introduction?
"Once in orbit, the spacecraft was supposed to deploy a large sail, upon which photons from the Sun would push, thereby increasing the spacecraft's velocity (the contributions from the solar wind are similar, but of much smaller magnitude)."
"Photons pushing", "similar to solar winds"... Wouldnt it be much simpler and clearer to say something along the lines of "would use solar radiation pressure to accelerate the spacecraft"? Seems needlessly roundabout 79.71.159.236 (talk) 22:48, 12 May 2017 (UTC)
replies: text: To me, rather than "strange" I'd call it simplified, perhaps overly so, I don't know.  I did go ahead and add the link, Radiation pressurepush.  Paine Ellsworth  put'r there  03:57, 10 June 2017 (UTC)
