First man in space: The first manned space flight lasted 108 minutes, and was on April 12, 1961 by Yuri Gagarin, a Soviet cosmonaut.

According to Indian mythology, there are 4 Yugs
Satyug - consists of 172,800 years (1+7+2+8 = 18 = (1+8 = 9)
TretaYug consists of 1296000 years (1+2+9+6 = 18 = (1+8 = 9)
DwaparYug consists of 864000 years (8+4+6) = 18 = (1+8 = 9)
Kaliyug consists of 432000 years (4+3+2) = 9
