Apollo LM rendezvous with CM[edit]

The article needs to discuss the rendezvous in lunar orbit of the returning lunar ascent module and the command module, which was a key element of the Apollo mission model. Or is that already covered by an article to which this one could be linked? Sdsds 05:43, 4 April 2007 (UTC)

Ah found it. Lunar orbit rendezvous. Now: how to work it into this article? Sdsds 05:45, 4 April 2007 (UTC)
Perhaps you can make a section on Major rendezvous operations, list them, and include (link to) the one above. s1 18:36, 6 May 2007 (UTC)

Additional information[edit]

I suggest that the article requires a summary of the specific actions required to achieve a rendezvous. I recall that it basically consists of - (1) the second craft attains a cicular orbit of the same altitute as the first craft (2) whichever craft is behind (ie. chasing) then catches up by dropping to a slightly lower orbit, thereby having a slightly higher obital velocity (3) final manoevering to bring the 2 craft into contact. I will look for a relevant article on the NASA site. Logicman1966 23:41, 21 July 2007 (UTC)

The math is not trivial. As a reference may I suggest chapter 2 of Automated Rendezvous and Docking of Spacecraft by Wigbert Fehse? Stunningly, most of this is available online at Google Books. (sdsds - talk) 04:48, 22 July 2007 (UTC)
Oh: it would also be great to discuss approaches made on the v-bar vs. those made on the r-bar. SpaceFlightNow had some coverage of this. (sdsds - talk) 04:54, 22 July 2007 (UTC)

Plural trouble[edit]

I am concerned that in several places in the article, including at least one section heading, "rendezvous" is used as the plural of "rendezvous". To be (perhaps pedantically) correct, this should probably be spelled "redezvouses" or some such. Should the occurances in the article all be changed? (sdsds - talk) 00:06, 4 October 2007 (UTC)

If we are going to be pedantic, the plural of rendezvous, despite being pronounced differently, is still spelt 'rendezvous' Ted BJ (talk) 13:09, 27 January 2009 (UTC)


It would be great to have some more information/article(s) on docking and docking devices such as docking rings. Suprisingly any relevant information on these seems to be very rare. Jiri Svoboda 17:52, 4 November 2007 (UTC)

Docking vs. Berthing[edit]

I have heard of a technical distinction between docking and berthing. In this usage,

  • docking is the "controlled crash" of two vehicle masses into one another via standard spacecraft reaction control (flight dynamics) such that a mechanical docking mechanism of some sort is engaged, and subsequent airlock etc. can be established. In contrast,
  • berthing is the movement of two spacecraft into the same orbit, with only a few meters of separation, and very precise station-keeping. Once in these relative positions, an electronically-controlled mechanical arm (like Canadarm or Dextre) are used to make a mechanical connection between the two vehicles, and then the mechanical arm is used via electric control to bring the two craft into a stiffer mechanical connection, and for some vehicles (e.g. H-II Transfer Vehicle into a subsequent airlock connection.

Two questions. Is such a distinction made in standard space literature? Does anyone know of a good source for this distinction? I don't see the distinction made in the article today but think it may be a quite useful addition given that both of these variants are widely practiced in space today. Cheers.

Here is a source[1] that describes the Berthing process for the Japanese HTV with the ISS. Might be a useful illustration of berthing for the article if we can find a verifiable mainline source that makes the berthing/docking distinction. N2e (talk) 20:02, 2 January 2011 (UTC)

China completes first space docking: November 2011[edit]

A first for China, a successful docking of two unmanned spacecraft:

Disputed Gemini 8 addition[edit]

This text recently inserted by an IP needs to be removed from here, not because it is uncited, but because it is out of scope in this article:

Shortly after docking, one of 16 Gemini spacecraft thrusters experienced an electric short, sending the spacecraft into a 1 RPS spin. Neil Armstrong & Dave Scott came very close to blacking out and being the first crew to die in space. It took more than 30min to get the Gemini 8 spacecraft under control by isolating which thruster was misfiring, as a result most of the fuel was used up for the primary system and much of the fuel for the re-entry thrusters was consumed trying to stabilize the spacecraft. The mission was cut short, but still accomplished it's primary goal of the 1st docking in space and the spacewalk by Dave Scott cancelled.

This article is about the subject of rendezvous and docking. Docking was successfully achieved, and what happened afterwards is irrelevant to this article. There is a hyperlink to the Gemini 8 mission, which is where this kind of detail belongs. You're welcome to merge it in there.

Also notice, the Citation needed tag was not put in the place intended; it's by a reference to Gemini 6. JustinTime55 (talk) 15:58, 2 August 2012 (UTC)

Soyuz & Progress launch & rendezvous with ISS in 6 hours[edit]

You got to explain how they were able to rendezvous and dock the progress transports and Soyuz in only 6 hours. There must be some major differences to the traditional way to do it. — Preceding unsigned comment added by (talk) 07:59, 2 April 2013 (UTC)
