I'm a science journalist and host of Cosmic Controversy (brucedorminey.podbean.com) as well as author of 'Distant Wanderers: the Search for Planets Beyond the Solar System.' I primarily cover aerospace and astronomy.
As the years click by and timeframes for unmet space goals fade in the rear-view mirror, it’s no wonder the public’s eyes tend to glaze over at the mere mention of crewed missions beyond low-Earth orbit.

This should give greater numbers of the public access to the overview effect, a transcendent cognitive shift that strikes astronauts who get a glimpse of planet Earth against the blackness of space. But all without crossing the Karman line, a 62-mile-high line of demarcation between the edge of Earth’s atmosphere and outer space.Grandiose ideas about extracting mineral riches from near-Earth asteroids which were so popular fifteen to twenty years ago have lately gone nowhere.
