Which one is not true about the astronaut mentioned in the news? [br] [original

To the great relief of the U.S. space agency NASA, a spacewalking astronaut has solved a problem with the shuttle. But mission controllers say another irregularity might require an additional spacewalk.
    Shuttle managers admitted they were apprehensive about sending astronaut Steve Robinson out to Discovery’s fragile underside, where some ceramic tiles had already been chipped by launch debris falling from Discovery’s external fuel tank.
    But NASA officials felt they had no choice. Two pieces of heat-resistant fabric wedged between the tiles had popped out a few centimeters, threatening to make the searingly-hot, but normally smooth airflow beneath the shuttle even hotter by creating pockets of air turbulence during Monday’s re-entry.
    So astronaut Robinson was moved cautiously to the area on the end the robot arm mounted to the International Space Station, where Discovery is docked for a maintenance visit. He carried only the tools needed for the job, forceps and a hacksaw, for use if he could not pull the fabric out with his fingers.
