People interest on learning about space has been even from the ancient days without any technological discoveries like telescope. Neil Armstrong, an astronomer, is the first to land on the moon. At first, many people were cynic on the fact behind Neil Armstrong journey and hesitate to recognize the achievements of United States.
Even Russian government has commented on the impression of the Neil Armstrong foot on the moon as the Hollywood-made snap just created by United States to show they are in ahead of the competition of determining the space components.

Both the type of Astronomy is essential in determining the space factors.
