There will be a 4th space walk

The two astronauts on Discovery ship finished their 3rd space walk but could not finish the solar battery, so NASA had to decide to make the fourth trip. Thus, the ship will return. about the earth one day late compared to the plan.

'We will make the 4th space walk on Monday, December 18. With the results of this 3rd time, I believe the work will be completed on the next walk ' - said Mr. John Curry, Flight Manager of the International Space Station (ISS).

Astronauts are finding ways to add the ISS's power supply system with new batteries, which are able to adapt to the system and allow more power to be produced. The work has now completed 65%. In its history, NASA never had to perform a task that required four times the space walk.

Discovery ship took off from Mui Canaveral, Florida on December 9 with an estimated 12-day flight time, to install a new electrical system on the ISS.
