NASA is working on nanostatkami space, able to move with 1/5 the speed of light. But if they survive the journey to our nearest star, alpha Centauri?
, press releases
In April this year, a team of scientists with Stephen Hawking at the head and billionaire Yurim Milnerem announced a Breakthrough Starshot project, which is designed to send a spacecraft the size of a postage stamp to our nearest star system alpha Centauri. If the ship StarChip traveled with 20%. the speed of light, he can catch up to the target in just 20 years. But is it possible for so long in space not naruszyłby its electronics?
NASA Scientists and Korea Institute of Science and Technology (KIST) recognize that the biggest problem for nanostatku cosmic radiation. Just as with high energy radiation can be hazardous to astronauts, are a long time in outer space, maybe it is also bad for the layer of silicon dioxide components of the spacecraft. The risk of failure can be reduced to minimize the impact of cosmic radiation, but it can greatly prolong the mission time.
Another option is to add additional armor protective electronics of the spacecraft, although it may translate to the increased mass of the ship and, consequently, reducing its desired maximum speed. But there is a way to handle it.
Scientists believe that the best solution would be to use samoleczących himself transistors, which, in the case of excessive exposure – automatically will warm and fix. The system automatically turns off in case of malfunction, and when regeneration is complete, is switched on again. This transistor was created by scientists from KIST.
laboratory Testing of transistor with nanowire showed that the heating process allows the flash memory on the regeneration approx. 10 000 times, and DRAM memory in 1012 times. Although at the moment this is only a hypothetical solution nanotranzystory can be used in interstellar space missions, such as Breakthrough Starshot.
