Civil, national security, and commercial are mentioned as three distinct space activities. Modern information, software engineering, and computing technologies have numerous critical contributions to make toward the success of future space missions. In February 2008, the Conference on Disarmament agreed that the term "outer space" means the space above the Earth in excess of 100 km above sea level. The successful implementation and application of the international law governing space activities depend largely on the understanding, accepting, and implementing of such laws by adopting domestic policies that assure such activities. Exploring outer space has always been a challenge for humans who were curious to find what lies above and beyond our immediate universe. In 2006, 14 space agencies came together to begin a series of discussions on global interests in space exploration. The main challenge that needs to be globally accepted and plans developed accordingly, is how to use space for the benefit of the Earth and its entire people.
