During the first walk on July 8, the two astronauts checked the crane extension at the end of the shuttle's 30-meter-long robot arm. This is the device used for emergency repair of the ship's outer shell in unfavorable locations. So the two most important missions in the journey to space this time of Discovery ship have been completed.

The US Aeronautics and Space Administration (NASA) said the second walk was done in 6 hours and 47 minutes and is expected to be taken on Tuesday, with the aim of testing repair capacity. Carbon bonding samples (RCC), a compound used as a heat-insulated vessel.

After the explosion of the shuttle Columbia in February 2003, this flight of Discovery ship was especially expected by American experts. After two delays due to bad weather Discovery ship was launched into space on the National Day 4-7, brought to the ISS seven astronauts and is expected to return to Earth on July 17.

The images taken from ISS show that this is the most "clean" space shuttle in the last 25 years and the cracks in the insulation of the previously discovered vessel have absolutely no effect. After studying hundreds of photos of insulated shells from Discovery, NASA analysts confirmed the ship was " completely safe" to be able to return to Earth as planned.
