message: "the craft was designated Vega, a contraction of Venera and Gallei (from Halley, as the Russian language does not have the letter "H")"
The Russian language does not have the letter "H"?!? It certaily does have the letter (and the sound) "H", and it's written as "X", in the Russian alphabet.
OK, maybe the name "Halley" is "Gallei" in Russian, but not because of the lack of the letter "H".
Any Russian speakers can clear this up, please? :)
:It's not quite the same H sound.  In any case, Russian commonly changes H's in foreign words to G's: Hitler → "Gitler", etc. Perhaps we could just say Gallei is Russian for Halley and leave it at that. -- Curps 15:06, 7 Feb 2005 (UTC)
replies: text: English "H" sound doesn't exist in Russian. The "X" Cyrillic letter is commonly transliterated back as "kh". It's a much more closed sound, pronounced further towards your mouth, as opposed to the English "h". See also Kha for further info in more correct phonetic terms. BACbKA 20:28, 14 July 2005 (UTC)

message: This is one of three pages that are for the most part redundant, the others being Vega 1 and Vega 2. The three pages should be merged into one page; I'm guessing the resulting single page would be about half the size of the three current pages. --Dan Griscom (talk) 03:33, 25 December 2007 (UTC)
replies: text: Oppose - it is common practice to have seperate articles for individual missions, I can't see much of a reason to change this now. --GW_SimulationsUser Page | Talk 21:43, 9 January 2008 (UTC)

message: I have a question: The balloons in the Vega mission used helium as lifting gas. As explained in 'Lifting gas', this is not necessary in this quite dense atmosphere. Helium has the disadvantages of diffusing easily through a balloon's wall, the need to be transported in a compressed cilinder, and having to be inflated into the balloon at the right moment.
That raises the question why they didn't simply bring some water in this balloon? During the journey in interplanetary space it would stay compactly frozen; as soon at it will enter the hot venus atmosphere (during a parachute descent) it will be heated to steam, automatically inflating the balloon. No pressure vessel needed, no special valves to let the gas into the balloon: fewer things that can fail. The lifting power of steam on Venus will certainly be sufficient to float a balloon in Venus' atmosphere and it will not easy diffuse through the balloon wall.
Who can explain why they have chosen for helium? If you have a good explanation, please add it to the text of this article. Erik Wannee (talk) 20:03, 1 June 2011 (UTC)

message: Does anybody know if the Vega program was named to commemorate the Vega Expedition, the first to navigate the Northeast Passage and the first circumnavigation of Eurasia? It seems quite probable, however we need a reliable ext ref. Cheers. --Mais oui! (talk) 09:20, 18 April 2013 (UTC)
