Machu Picchu is the hispanicized spellingof the Quechua name Machu Pikchu. It means old peak (Quechua machu old + pikchu peak).
In April 1961, cosmonaut Yuri Gagarin's spacecraft was launched at 9:07, orbited Earth once and landed at 10:55 in the Soviet Union.
The official explanation of how Yuri Gagarin died did not go unchallenged, and not by Leonov alone. Many theories, ranging from the technical to the conspiratorial, have been raised in the decades since. [Vostok 1: Yuri Gagarin's Historic Manned Spaceflight Recalled (Video)]
