Tomorrow February 7, 2010, at 4:39 a.m. EST (11:39 am for Greece) the Space Shuttle Endeavour will be launched in to Space for mission STS-130. This is a historic launch because it is the last one that would take place at night. The flight will last 13 days and will include 3 spacewalks in order to install the node 3 'Tranquility' ISS module. In this node there is the cupola, a 7 window observation where the astronauts can have a panoramic view of the earth and space. This topic will be updated after the launch.---
