Orbital Telescopes Are Always Watching
Meanwhile, as astronauts train on Earth for dealing with space rocks, Johnson and his team at NASA continue to use the project’s finances as well as resources, like massive orbital telescopes, to monitor the cosmos. These telescopes are humanity’s best early warning system in case a large asteroid enters our solar system and makes its way towards Earth. The sooner NASA is aware of the problem, the more time they’ll have to prepare for the threat.
