Space science is the study of everything above and beyond the surface of the Earth, from Earth’s atmosphere to the very edges of the universe. Space Technology refers to the technology in satellites and ground systems used by space scientists to study the universe (looking up) and the earth (looking down), or to deliver services to users on the ground. The vast majority of satellites are launched into space to provide services to people on Earth.
Satellite is an object which has been placed into orbit by human endeavor. Such objects are sometimes called artificial satellites to distinguish them from natural satellites such as the Moon. Space is the property of the universe, in which matter is physically extended and objects have positions relative to one another.
In classical mechanics, space was treated as being separate from time and is thought of as one of the few fundamental physical quantities. In Isaac Newton’s view space was absolute, and held that it exists permanently and independently of whether there is any matter in the space or moving through it.
Space exploration is the use of astronomy and space technology to explore outer space. Physical exploration of space is conducted both by human spaceflights and by robotic spacecraft. Space exploration has often been used as a proxy competition for geopolitical rivalries such as the Cold War.
The first human spaceflight was Vostok 1 (East 1), carrying 27 year old cosmonaut Yuri Gagarin on April 12, 1961. The spacecraft completed one orbit around the globe, lasting about 1 hour and 48 minutes. Gagarin’s flight resonated around the world; it was a demonstration of the advanced Soviet space program and it opened an entirely new era in space exploration — human spaceflight.
Space Shuttle Discovery (Orbiter Vehicle Designation: OV-103) is one of the three currently operational orbiters in the Space Shuttle fleet of NASA, the space agency of the United States. (The other two are Atlantis and Endeavour.) When first flown in 1984, Discovery became the third operational orbiter, and is now the oldest orbiter in service. Discovery has performed both research and International Space Station (ISS) assembly missions.
Space technology is technology that is related to entering space, maintaining and using systems during spaceflight and returning people and things from space.
Space technology has a huge impact on the everyday lives of people; and something as simple as checking the weather or watching satellite television or receiving a parcel guided by satellite, it touches most people’s lives on any given day.
Watch the video related to Space Science
On 2nd July 1967, a satellite picked up a huge burst of gamma rays. Was it evidence of a nuclear bomb test in space? Or was it from a much bigger explosion in deep space? Can Einstein’s famous physics equation E=MC2 help? Watch this video from BBC science show ‘Death Star’ to find out more.
Help answer the question about Space Science
How much further is military space science than NASA and other non-military public or private agencies?I know the military develops all sorts of underground projects in every other arena. Are there significant advances made by the military in space exploration/science that hasn't been accomplished by private agencies?

I'm specific to space technology stuff myself. The answer is rather complex, because there has been some significant peaceful transfers of technology since the fall of the Soviet Union. It is rather interesting that the technology is being shared between former mortal enemies, while Europe (which has a closer political relationship with Russia) is not benefiting. It has also been a one way street because the Soviet Union, despite communism, was far ahead in commercialisable booster technology. A comparison of the SSME with its Soviet sister, the RD-0120 (not to be confused with the RD-120) shows how this is the case. Check it out at http://www.astronautix.com (excuse the pop-ups.)
The most significant example of technology transfer is the Energomash RD-180 engine now used in the Atlas V booster. Another example is the Sea Launch, a joint venture between Boeing and Russia (not sure which company). The Sea Launch is a poor example as a technology merger, because it is a 100% Russian booster (Proton 4th stage as a third stage on the two stage Zenit.)
Another huge factor in international cooperation, which will become really obvious when Soyuz starts launching from Kourou next year, is geography. The closer to the equator your launch site is, the better off you are. The minimum inclination of a launch site is its latitude, unless it has restrictions due to range safety. Russia's minimum inclination site is Baikonur (actually closer to Tyuratam if you look for it in an atlas) at 51.6deg. The lowest inclination site actually in Russia (Baikonur's in Kazahkstan) is Plesetsk, at 63deg. This means that Russian boosters in commercial applications are seriously overpowered when compared to boosters from other countries (USA's Cape Canaveral is 28.5deg, Kourou is 4deg, but launches to 7.2deg.) Myself and others have occasionally spun the globe to find the "perfect" launch site. I thought of Nairobi, Kenya, another (someone at http://www.orbitersim.com) thought of Sumatra, both very difficult places to set up a launch site because of politics and poverty. What is really needed is an international equatorial spaceport, and an international body to govern its operation.
WASA? WASAP wit dat? I made up an "alternate history" fictional universe with an organization called the "International Space Exploration Alliance" or INSEA, which became this international body in 1952 (in the INSEA universe.) By today, commercial companies operate the fully reusable Bluestar booster from several launch and recovery sites, including Nairobi, Meru, and Lamu, which are run by INSEA. I haven't looked up the rest in the "African Booster Corridor" yet, but many are needed because reusable piloted boosters like Bluestar need places to land after expending all their propellant during an ascent, and in case of aborts.

Wow. They even have a Fourth of July in space. So that’s how the bugs feel when we set off fireworks. xD
