Tonight - the first spacewalk on mission STS-130

during which the astronauts will remove the tranquility component and the observation deck cupola attached to it from the cargo deck of the shuttle and connect to the station

The fifth day of the astronauts on the space shuttle Endeavor and the space station began at 23:14 Israel time with the wake-up song "Yom Yaffe" by the band U2 played for astronaut Kay Hair.

The main event expected today is the first spacewalk in this mission which will be accompanied by the activation of the station's robotic arm to install a tranquility component. The spacewalk is expected to start at 04:09 am Israel time although the team members are even ready to start earlier.

Holki Hal Nicholas Patrick and Bob Behnken spent their night sleeping in an airlock filled with oxygen, instead of the normal air mixture of oxygen and nitrogen. This is to get used to the suits and avoid space sickness while outside the station.

The two would prepare the Tranquility Component for transfer from the Endeavour's cargo deck to near the station and then they would attach the cables to it. Terry Wirts and Hair will operate the robotic arm to install the Tranquility component and the attached cupola observation deck.

The spacewalkers will also remove a tool platform from the dexter arm of the tena during the Tranquility transfer maneuver. Station Commander Jeff Williams and Heyer will start by testing the leakage from the components connecting Tranquility to the new component to be sure that it can be connected to the compressed area of ​​the station without fear of air leakage from the entire station after connection.
