Walk in space to celebrate the moon's day

Two shuttle astronauts Endeavor made a space walk yesterday to celebrate the 40th anniversary of the human landing on the moon for the first time.

This is the second walk since Endeavor arrived at the International Space Station (ISS) last Friday. Two astronauts David Wolf and Thomas Marshburn installed a 15 cm-diameter disk antenna on the ISS for future use. In addition, they installed a large pump and engine for the station's transport compartment. The walk takes 7 hours. ISS astronauts were worried when Marshburn dropped the 25-meter-long belt (to connect astronauts to the station). However, he was still safe thanks to a shorter belt. The antenna installation interrupted until Marshburn found the belt.

The space walk was set on Monday to celebrate the 40th anniversary of the arrival of two astronauts Neil Armstrong and Buzz Aldrin on the moon. It was the 202th walk conducted by Americans since the Apollo 11 ship flew up to ' Ms Hang '.

Earlier, in a press conference in Washington on the morning of July 20, some astronauts who once went to the moon, including Armstrong and Aldrin, said the $ 100 billion for the International Space Station did not bring Great results. According to them, the ISS should be used as a frontier to fulfill the ambition of bringing people to Mars and small meteorites.

' We spend a lot of money on ISS but hardly get anything .', Said Jim Lovell, leader of the Apollo 13 astronaut.

Meanwhile, the toilet, worth $ 15.6 million, has been operating again after being broken on Sunday.

Endeavor cannot dispose of waste when it is connected to the ISS, because urine can corrode the space lab they have just installed.
