on the other hand, was described as calm; about half an hour before launch his pulse was recorded at 64 beats per minute. Launch 06:07 UTC Launch occurred from the Baikonur Cosmodrome Site No.1. Korolev radioed, "Preliminary stage..... intermediate..... main..... lift off! We wish you a good flight. Everything is all right." Gagarin replied, "Let's go! (Poyekhali!)." 06:09 (T+ 119 s) The four strap-on boosters of the Vostok rocket used up the last of their propellant and dropped away from the core vehicle. 06:10 (T+ 156 s) The payload shroud covering Vostok 1 was released, uncovering a window at Gagarin's feet, with an optical orientation device (lit. "look" or "glance"). 06:12 (T+ 300 s) The rocket core stage used up its propellant and fell away from the capsule and final rocket stage. The final rocket stage ignited. 06:13 Gagarin reported, "...the flight is continuing well. I can see the Earth. The visibility is good.... I almost see everything. There's a certain amount of space under cumulus cloud cover. I continue the flight, everything is good." 06:14 Vostok 1 passed over central Russia. Gagarin reported, "Everything is working very well. All systems are working. Let's keep going!" 06:15 Three minutes into the burn of the final rocket stage, Gagarin radioed, ", I can't hear you very well. I feel fine. I'm in good spirits. I'm continuing the flight..." Vostok 1 started to move out of radio range of the Baikonur ground station. 06:17 The rocket final stage shut down and Vostok 1 reached orbit. Ten seconds later the rocket separated from the capsule. Time in orbit 06:18 UTC (T+ 676 s) Gagarin reported, "The craft is operating normally. I can see Earth in the view port of the . 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
