The First Successful American Satellite on 31th January in 1958!

Launched less than two months after Vanguard 1A, the first American attempt to compete with Sputnik, blows up on the launchpad, Explorer 1 (officially called Satellite 1958 Alpha) achieves an orbit extending an astonishing 1,560 miles (2,500 kilometers) above the Earth. This leads to the first great scientific discovery of the space age, when instruments designed by Iowa physicist James Van Allen find the radiation belts now named in his honor. The 31-pound (14-kilogram) satellite transmits until May 23, when its batteries die, but it remains aloft for more than 12 years.

The First Animal in Orbit on 3rd November in 1957!

Having stunned the world with the first orbital space launch, Sputnik 1, less than a month before, the Soviet Union tries for a second coup by launching a dog named Laika on a one-way journey on a hastily completed follow-up mission, Sputnik 2. The dog survives the launch, but Soviet secrecy masks her ultimate fate for many years. It now appears that even though she had a week's supply of food, Laika died within hours, possibly due to a life-support failure that caused her canister to overheat.

First Artificial Satellite 4th October in 1957!

The Soviet Union ushers in a new era the space age with the launch of Sputnik 1. A technological feat, the beach ball size satellite weighs 184 pounds (84 kilograms) and takes 98 minutes to orbit Earth. The launch grabs the world's attention and catches the U.S. off-guard. The first successful American satellite doesn't get off the ground until January 31, 1958.

Comming 8th July NASA STS-135 Mission Begin For Final Flight !

Space shuttle Atlantis is set to liftoff for the final flight of the shuttle program. 'STS-135' a 12-day mission to the International Space Station. Launch is currently targeted for July 8.

In 2010 NASA Authorization directs NASA conduct the STS-135 mission. The Space Shuttle Program has added on the mission to the manifest to decorate for a potential target launch date in early July in this year.

The Raffaello multipurpose logistics module to deliver supplies which will be carry by Atlantis. Atlantis also carry Logistics & spare parts to the International Space Station. The mission also will fly a system for investigate the potential for robotically refueling existing spacecraft and then return a failed ammonia pump module to help NASA better understand the failure mechanism and improve pump designs for future systems.

In This Year Last ISS Tour photo And Video Collection From NASA!

Last April on 2011, The Sky Exploration Institute of NASA finished Expedition 27 Flight on ISS Tour. They published some Photo and Video which they collected. Collected Expedition 27 Flight Engineer Cady Coleman flies through the International Space Station with a High-Definition video camera. This Photo and Video Collected from ISS tour 21 April in 2011.

The First International Space Station Was 'Salyut -1'

The first space station was Salyut 1 was which put into orbit. The Soviets launched it from Baikonur Cosmodrome on April 19, 1971 using a three-stage Proton launch vehicle. Before deorbiting and reentering the atmosphere over the Pacific Ocean in October it completed with 362 orbits. It was destroyed by frictional heating during its return.

The three pressurized areas had a collective habitable volume of 100 cubic meters. Two of these could be entered into it. Eight big chairs is the primary area contained, several control panels and approximately twenty portholes. The other area are held the control and communication equipment, power supply, life support system and other auxiliary equipment.

James Webb Space Telescope ISIM on 'Spin Cycle'!

Prior to taking a new telescope into space, engineers must put the spacecraft and its instruments through a "spin cycle" test for durability to ensure they'll still work after experiencing the forces of a rocket launch. Finding out they don't work once they're in orbit is too late. The structure that houses the science instruments of the James Webb Space Telescope is undergoing that cycle of tests during the weeks of May 23 and 30 at NASA's Goddard Space Flight Center in Greenbelt, Md. This structure is called the Integrated Science Instrument Module, or ISIM.

The Webb telescope will experience significant shaking and gravitational forces when it is launched on the large Ariane V rocket. The ISIM structure will house the four main scientific instruments of the telescope.

During the testing process, as the ISIM structure is being spun and shaken, engineers take measurements to compare with their computer models. If there are discrepancies, the engineers hunt for the reasons so they can address them. The huge centrifuge will spin at speeds close to 11 rpm, exposing the ISIM structure to about 10 times the force of gravity.
