Editing Vostok 1 (section)

===Soviet reaction===
Gagarin's flight was announced while Gagarin was still in orbit, by [[Yuri Levitan]], the leading Soviet radio personality since the 1930s. Although news of Soviet rocket launches would normally be aired only after the fact, [[Sergei Korolev]] wrote a note to the Party Central Committee to convince them that the announcement should be made as early as possible:
<blockquote>
"We consider it advisable to publish the first [[TASS]] report immediately after the satellite-spacecraft enters orbit, for the following reasons:

(a) if a rescue becomes necessary, it will facilitate rapid organization of a rescue;

(b) it precludes any foreign government declaring that the cosmonaut is a military scout."<ref name="HarfordTASS">{{cite book |last1=Harford |first1=James |title=Korolev: How One Man Masterminded the Soviet Drive to Beat America to the Moon |date=8 April 1997 |publisher=John Wiley & Sons |isbn=0-471-32721-2 |page=169}}</ref>
</blockquote>
The flight was celebrated as a great triumph of Soviet science and technology, demonstrating the superiority of the socialist system over capitalism. Moscow and other cities in the USSR held mass demonstrations, the scale of which was comparable to [[Moscow Victory Parade of 1945|World War II Victory Parades]]. Gagarin was awarded the title of [[Hero of the Soviet Union]], the nation's highest honour. He also became an international celebrity, receiving [[Yuri Gagarin#Awards and honours|numerous awards and honours]].<ref>{{Cite book |last=Pervushin |first=Anton |url=https://books.google.com/books?id=kMGlvz53P3cC&dq=%D0%B4%D0%B5%D0%BC%D0%BE%D0%BD%D1%81%D1%82%D1%80%D0%B0%D1%86%D0%B8%D0%B8+%D0%B2+%D0%B4%D0%B5%D0%BD%D1%8C+%D0%BA%D0%BE%D1%81%D0%BC%D0%BE%D0%BD%D0%B0%D0%B2%D1%82%D0%B8%D0%BA%D0%B8&pg=PT488 |title=108 минут, изменившие мир |date=2011-04-12 |publisher=Litres |isbn=978-5-457-02230-0 |language=ru |trans-title=108 Minutes That Changed the World |chapter=7.1 Гражданин мира |trans-chapter=7.1 Citizen of the World}}</ref>

Gagarin's informal reply ''Poyekhali!'' ("Let's go!") became a historical phrase used to refer to the arrival of the [[Space Age]] in human history.<ref>{{Cite book |last=Pervushin |first=Anton |url=https://books.google.com/books?id=kMGlvz53P3cC&q=%D0%BE%D0%BD+%D1%81%D0%BA%D0%B0%D0%B7%D0%B0%D0%BB+%D0%BF%D0%BE%D0%B5%D1%85%D0%B0%D0%BB%D0%B8&pg=PT440 |title=108 минут, изменившие мир |date=2011-04-12 |publisher=Litres |isbn=978-5-457-02230-0 |language=ru |trans-title=108 Minutes That Changed the World |chapter=6.2.
