| There will be intense concern in Europe and Japan, however, over the latest developments. | |
| The rip problem is compounded by the discovery at the weekend of excessive wear in a motorised joint driving solar panels on the far side of the station. The gear is used to turn the wings to follow the Sun. | |
| But Nasa has now limited the joint's use to prevent total failure; and this restricts the station's capacity to generate electricity. The Japanese and European space agencies will be eager to learn that the current difficulties will not hold up further expansion of the outpost. | |
| The torn panel was almost completely unfurled when the rip was spotted. The astronauts beamed down photos of the torn and crumpled section so Nasa engineers could analyse them. | |
| Nasa has added a day to Discovery's mission so that a detailed inspection of the troublesome joint can be carried out. This will take place on Thursday. | |
| Discovery is due to undock from the space station on Monday and return to Earth on 7 November. |
