Wearable gadgets that vibrate to provide orientation cues, however, have been identified by scientists to significantly improve the efficacy of this training, making spaceflight marginally safer.
The sky is no longer the limit - but flying is risky. We lose many of the clues we need to orient ourselves when we leave the Earth's surface, and this spatial disorientation can be fatal. Astronauts typically require extensive training to protect themselves against it. However, scientists h
