After checking for minor cracks in the wing and nose section of the shuttle using laser beam and a robot, (this is a new technique since columbia disaster and the crew did it on their last space walk) the crew reported that the thermal protection system is working extremely fine. But now the concern is shifted to one of the hydraulic cylinder which delivers power for maneuvering and controlling the shuttle. One of its cylinder leaks suspicios liquid nitrogen. If it is confirmed, then upon re-entry the fuel might burn causing fire hazard which is dangerous for the crew and for the shuttle! Data are collected based on experiments conducted on sunday. Reports are pouring from ground station after careful analysis that says the issue is minor and that the landing will be successful. And lo they did it! NASA has once again successfully demonstrated the world about their design of space shuttle-the robust machine man-has-ever-built!
