[edit] Soviet FAI rules cheating claims

There's a discussion going at Talk:Boundary_to_space#The_U.S._definition that's partly Gagarin's parachuting out of the capsule for landing.Ropers 19:56, 26 Jul 2004 (UTC)

[edit] = facts

is is stated on http://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/19630043160_1963043160.pdf that the perigee was 188 km, and the agogee was 302 km. this is not the same as in the article. --80.63.213.182 14:11, 15 August 2006 (UTC)

[edit] Altitude or attitude?

In a number of places this article mentions the spacecraft's 'altitude' when I am sure what was intended was 'attitude'. I will edit the article accordingly. Chris Jefferies 13:53, 10 December 2006 (UTC)


Countdown I think it's slightly misleading to use the term 'countdown'. That implies something like "ten, nine, eight" (or even "desyat, devyat, vosem"). Russian/Soviet space launches don't feature one. The phrase in the original Russian is "minutnaya gotovnost" -something like "a minute's preparation time". This minute was in fact several minutes before the actual launch (see [1]. And Gagarin's call sign, strictly speaking, is "Siberian pine", not "Cedar" (see [2].) 62.181.46.66 13:38, 28 May 2007 (UTC) Al


[edit] Reentry details

I believe the reentry module did not "automatically settle into proper attitude" after having being released from the spacecraft, so I will remove this statement. In fact, Gagarin later reported that gyrations continued for a while and then changed to 90 degree oscillations. Apparently this did not matter much since the capsule was spherical, so before the parachutes were deployed the attitude did not matter and after that the parachutes probably stopped the rotation.

[edit] Did Vostok 1 complete a full orbit?

If the launch point for the Vostok 1 mission was at Baikonur Cosmodrome which is located at 45 °N 63 °E and the landing point for the Vostok 1 mission was near 51° N, 46° E this would indicate that the Vostok 1 mission only covered 343 degrees of Longitude. However from a reference point of Latitude, Vostok 1 completed 366 degrees.

In order to qualify for a full orbit, does a spacecraft have to pass both through the Latitude and Longitude references or is one sufficient? If one is sufficient, then what is the differentiating point between sub-orbital and orbital flights?

While the flight profile clearly is in excess of what is commonly referenced to as “suborbital”, is it accurate to say that Gagarin was the first man to orbit the earth?

If not, then cosmonaut Gherman Titov onboard Vostok 2 would be the first man to orbit the earth. Gagarin completed a fractal orbital flight. —Preceding unsigned comment added by 130.221.224.5 (talk) 20:37, 15 October 2007 (UTC)

You forget, that orbital period is calculated relative to the stars, not to the Earth. During his spaceflight the Earth rotated per 360/24*108/60=27 degrees in the same direction as he flew (i.e. "ran away from him"). But difference in longitudes is some 17 degrees. So, relative to the stars, he completed even 10 degrees more than one orbit.86.100.231.115 21:56, 15 October 2007 (UTC)
Thanks for clearing that up —Preceding unsigned comment added by 71.62.169.83 (talk) 00:01, 16 October 2007 (UTC)
