The topic of the following conference is to discuss challenges that space environment represents to human activities in space and dangers to life and society on Earth. Space hazards are near-Earth objects (NEO), mainly human made, those that come from deep space in the form of dust, meteorites or asteroids and the Solar storms that define space weather.
