Repairs Continue to Launch Pad 39A

Launch Pad 39A




A backhoe is used during repair work under way on the flame trench on Launch Pad 39A at NASA's Kennedy Space Center. Damage to the trench occurred during the launch of Discovery on the STS-124 mission. A 75- by 20-foot section of the east wall was destroyed and debris scattered as far as the pad perimeter fence. Repairs are to be completed before the targeted Oct. 8 launch of Atlantis on the STS-125 mission.

Suiting Up - NASA International Space Station

Suiting Up

Attired in his Russian Orlan spacesuit, Russian Federal Space Agency cosmonaut Oleg Kononenko, Expedition 17 flight engineer, prepared for the July 10 spacewalk. During the full dress rehearsal "dry run" that took place on July 8, Kononenko and fellow cosmonaut Commander Sergei Volkov tested translation capability and the status of the suits' communications gear and other systems while in the Pirs Docking Compartment of the International Space Station.Durin the 6-hour, 18-minute spacewalk, they inspected their Soyuz TMA-12 spacecraft and retrieved a pyro bolt from it.

An Orbiting Partnership is Born

An Orbiting Partnership is Born - Apollo-Soyuz

On July 17, 1975, something momentous happened: two Cold War-rivals met in space. When their respective spacecraft rendezvoused and docked, a new era of cooperative ventures in space began.



For more than a decade, American astronauts and Russian cosmonauts have been regularly living and working together in Earth orbit, first in the Shuttle-Mir program, and now on the International Space Station. But, before the two Cold War-rivals first met in orbit in 1975, such a partnership seemed unlikely.

Since Sputnik bleeped into orbit in 1957, there had indeed been a Space Race, with the U.S. and then-Soviet Union driven more by competition than cooperation. When President Kennedy called for a manned moon landing in 1961, he spoke of "battle that is now going on around the world between freedom and tyranny" and referred to the "head start obtained by the Soviets with their large rocket engines."But by the mid-70s things had changed.

The U.S. had "won" the race to the moon, with six Apollo landings between 1969 and 1972. Both nations had launched space stations, the Russian Salyut and and American Skylab. With the space shuttle still a few years off and the diplomatic chill thawing, the time was right for a joint mission.

The Apollo-Soyuz Test Project would send NASA astronauts Tom Stafford, Donald K. "Deke" Slayton and Vance Brand in an Apollo Command and Service Module to meet Russian cosmonauts Aleksey Leonov and Valeriy Kubasov in a Soyuz capsule. A jointly designed, U.S.-built docking module fulfilled the main technical goal of the mission, demonstrating that two dissimilar craft could dock in orbit. But the human side of the mission went far beyond that.

NASA Small Magellanic Cloud

Extraterrestrial Fireworks


Reminiscent of a fireworks celebration, this Hubble Space Telescope image of a cosmic explosion that is quite similar to fireworks on Earth. In the upper right corner of the image, the Small Magellanic Cloud is a delicate glowing structure ablaze in a multitude of lavenders and peach. Nearby, a massive star has exploded as a supernova and begun to dissipate its interior into a spectacular display of colorful filaments.




The supernova remnant known as "E0102" is the greenish-blue shell of debris just below the center of the Hubble image. Its name is derived from its cataloged placement (or coordinates) in the celestial sphere. More formally known as 1E0102.2-7219, it is located almost 50 light-years away from the edge of the massive star-forming region, N 76, also known as Henize 1956, in the Small Magellanic Cloud.



Determined to be only about 2,000 years old, young supernova remnants like E0102 allow astronomers to examine material from the cores of massive stars directly. This in turn gives insight on how stars form, their composition and the chemical enrichment of the surrounding area. As well, young remnants are a great learning tool to better understand the physics of supernova explosions.



The Small Magellanic Cloud is a nearby dwarf galaxy to our own Milky Way. It is visible in the Southern Hemisphere, in the direction of the constellation Tucana, and lies roughly 210,000 light-years distant.Image Credit: NASA, ESA, and the Hubble Heritage Team (STScI/AURA)/J.

Making History

Whitson Makes History


Backdropped by a sparkling blue and white Earth, Expedition 16 commander Peggy A. Whitson participated in the 100th spacewalk for the construction and maintenance of the station.


Whitson made history as the first female commander of the station.


During the spacewalk, Whitson and flight engineer Dan Tani searched for the cause of partial loss of electrical power to one of the International Space Station's two Beta Gimbal Assemblies for starboard solar wings and examined damage to the starboard Solar Alpha Rotary Joint. Image Credit: NASA
