Quote:There’s a lot riding on NEOSSat and Sapphire, two Canadian satellites scheduled to be launched from India on Monday.
Atens are a group of near-Earth asteroids that orbit the sun elliptically and periodically cross Earth’s orbital plane.
“If it had come down in the middle of New York City it would have made a lot more noise than it did.”
In a recent interview, Alan Hildebrand of the University of Calgary said studies are already being done to see how a threatening asteroid can be deflected.
The planetary scientist said one option would involve exploding a device near an asteroid while another would use a spacecraft to pull it away.
Sapphire will contribute to the United States Space Surveillance Network, which currently tracks more than 22,000 pieces of space debris larger than 10 centimetres.
The data that’s collected will be used to warn satellite operators of potential collisions as a result of space debris. A cliche among space professionals is that space has become “congested, contested and competitive.”
Quote:Our choice to develop the direct soft push concept was driven primarily by two considerations; our sense that a demonstration of capability should be demonstrated within the next 20 years (given the anticipated public policy demand), and the fact that there were several cost-effective key technologies that were developing rapidly.
My problem with this 'soft push' option, is if they change it's trajectory then how do we know if it won't change other unknown asteroids' trajectories directly into Earth's path?
