Editing Vostok 1 (section)

===Time in orbit===
[[File:Vostok 1 orbit english.png|thumb|right|Ground trace of Gagarin's complete orbit; the landing point is west of the takeoff point because of the Earth's eastward rotation.]]
* '''06:18''' UTC (T+ 676 s) Gagarin reported, "The craft is operating normally. I can see Earth in the view port of the {{lang|ru-Latn|Vzor}}. Everything is proceeding as planned". Vostok 1 moved on over [[Siberia]] as it passed over the Soviet Union.
* '''06:21''' Vostok 1 passed over the [[Kamchatka Peninsula]] and out over the North Pacific Ocean. Gagarin radioed, "...the lights are on on the descent mode monitor. I'm feeling fine, and I'm in good spirits. Cockpit parameters: pressure 1; humidity 65; temperature 20; pressure in the compartment 1; first automatic 155; second automatic 155; pressure in the retro-rocket system 320 atmospheres...."
* '''06:25''' As Vostok 1 began its diagonal crossing of the Pacific Ocean from Kamchatka Peninsula to the southern tip of South America, Gagarin requested information about his orbital parameters: "What can you tell me about the flight? What can you tell me?". The ground station at [[Khabarovsk]] didn't have his orbital parameters yet, and reported back, "There are no instructions from No. 20 [code name for Korolyov], and the flight is proceeding normally." (Ground control did not know until 25 minutes after launch that a stable orbit had been achieved.)
* '''06:31''' Gagarin transmitted to the Khabarovsk ground station, "I feel splendid, very well, very well, very well. Give me some results on the flight!". At this time, Vostok 1 was nearing the VHF [[radio horizon]] for Khabarovsk, and they responded, "Repeat. I can't hear you very well". Gagarin transmitted again, "I feel very good. Give me your data on the flight!" Vostok 1 then passed out of VHF range of the Khabarovsk ground station.
* '''06:37''' Vostok 1 continued on its journey as the sun set over the North Pacific. Gagarin crossed into night, northwest of the [[Hawaiian Islands]]. Out of VHF range with ground stations, communications continued via HF radio.
* '''06:46''' Khabarovsk ground station sent the message "KK" via telegraph (on HF radio to Vostok 1). This was a code meaning, "Report the monitoring of commands," a request for Gagarin to report when the spacecraft automated descent system had received its instructions from ground control.
* '''06:48''' Vostok 1 crossed the equator at about 170° West in a southeast direction, and began crossing the South Pacific. Gagarin transmitted over HF radio, "I am transmitting the regular report message: 9 hours 48 minutes (Moscow Time), the flight is proceeding successfully. Spusk-1 is operating normally. The mobile index of the descent mode monitor is moving. Pressure in the cockpit is 1; humidity 65; temperature 20; pressure in the compartment 1.2 ... Manual 150; First automatic 155; second automatic 155; retro rocket system tanks 320 atmospheres. I feel fine...."
* '''06:49''' Gagarin reported he was on the night side of the Earth.
* '''06:51''' Gagarin reported the sun-seeking attitude control system was switched on; this oriented Vostok 1 for retrofire. The automatic/solar system was backed up by a manual/visual system; either one could operate the two redundant cold [[nitrogen]] gas thruster systems, each with {{convert|10|kg|lb|abbr=on}} of gas.
* '''06:53''' The Khabarovsk ground station sent Gagarin via HF radio, "By order of No. 33 (General [[Nikolai Kamanin]]), the transmitters have been switched on, and we are transmitting this: the flight is proceeding as planned and the orbit is as calculated." Vostok 1 was now known to be in a stable orbit; Gagarin acknowledged.
* '''06:57''' Vostok 1 was over the South Pacific between New Zealand and [[Chile]] as Gagarin radioed, "...I'm continuing the flight, and I'm over America. I transmitted the telegraph signal "ON".
* '''07:00''' Vostok 1 crossed the [[Strait of Magellan]] at the tip of South America. News of the Vostok 1 mission was broadcast on Radio Moscow.<ref>{{cite news |url=http://news.bbc.co.uk/onthisday/hi/dates/stories/april/12/newsid_2477000/2477715.stm |work=BBC News |title=1961: Soviets win space race |date=April 12, 1961}}</ref>
* '''07:04''' Gagarin sent another spacecraft status message, similar to the one at 06:48. This was not received by ground stations.
* '''07:09''' Gagarin sent another spacecraft status message, also not received by ground stations.
* '''07:10''' Vostok 1 passed over the South Atlantic, into daylight again. At this point, retrofire is 15 minutes away.
* '''07:13''' Gagarin sent a fourth spacecraft status message; Moscow received this partial message: "I read you well. The flight is going...."
* '''07:18''' Gagarin sent another spacecraft status message, not received by ground stations.
* '''07:23''' Gagarin sent another spacecraft status message, not received by ground stations.

The automatic orientation system brought Vostok 1 into alignment for retrofire about 1 hour into the flight.
