Nasa has created a new spacesuit that repairs itself if astronauts are hit by tiny meteoroids. The fabric contains a special gel that will instantly fill holes caused by natural missiles from space. The new suits will protect American astronauts sent to explore the Moon in the next decade. Space scientists are worried about tiny meteors raining down on the lunar surface. Holes 2mm wide can be automatically repaired by the fabric. Wire sensors will detect any bigger rips and sound an alarm to alert the astronaut. The suit material also contains tiny solar cells to generate power and silver-coated layers of polyester to kill bacteria. Delaware firm ILC Dover developed the wonder fabric for Nasa. They say it could also be used to build an inflatable moon base or space station, New Scientist reports today. |
