Talk:Proton rocket
From Wikipedia, the free encyclopedia
The following lines:
"They are stored at ambient temperatures avoiding the need for low-temperature-tolerant components and also allowing the rocket to sit on the pad indefinitely without need for continuous topping up of boiling off cryogenic fuels."
..is understandable, but what happens when the rocket reaches the altitude where there is no oxygen needed for burning process and thrust anymore? Then liquid oxygen must be poured to engine nozzles to keep the burning process and thrust active which still requires a cooling system even when still on launch pad. So, what does the Proton use when it reaches the "no-oxygen" altitude (if the article says there are no low-temperature-tolerant components needed)?? Is there maby enough oxygen released during the chemical reaction between two components itself?
- There's no such thing as the "no-oxygen" altitude. The point of a rocket engine is that it brings its own oxidizer, nitrogen tetroxide in this case. Nitrogen tetroxide is a liquid at room temperature. The other commonly used oxidizers are liquid oxygen (which needs to be kept cold) and ammonium perchlorate (for solid rockets). -- Sam, 29 July 2005
[edit] IMG
The porton rocket in the picture doesn't really look like being from NASA.
- It is from NASA [1]. There were many NASA people including Dan Goldin at the Baikonur Cosmodrome attending Zvezda launch (which is pictured). --Bricktop 15:26, 9 February 2006 (UTC)
[edit] First launch
Was it first launched in 1967 or 1965? The article says 1965 but the infobox says 1967.

- Both! The maiden flight of the Proton 8K82, the first version of the UR series rocket to be named "Proton", was on 16/07/65. The uprated Proton 8K82K, as described by the infobox, first flew on 10/04/67. --GW_SimulationsUser Page | Talk 18:10, 8 September 2006 (UTC)

- It's confusing that the data in the infobox is about a specific detail compared to the main article. A lot of people who view this page might get confused by this (I was)!
