A new planetary defense method would see a smaller version of the SpinLaunch's suborbital accelerator anchored to a near-Earth asteroid.
These types of asteroids are much more common than massive space rocks capable of destroying a city, but they are still capable of causing a lot of damage.SpinLaunch recentlyto high altitudes using its system, which uses a centrifuge mechanism to spin payloads at 10,000 g's before flinging them skyward. The company aims to eventually use its space catapult to launch small satellites and payloads to low Earth orbit with only a fraction of the fuel required for a traditional rocket launch.
When the payload reaches the asteroid, the centrifugal system anchors itself onto the space rock, extracting regolith at high speeds and flinging it outward. Using this method, The Aerospace Corporation says asteroids between 30 to 60 meters in width could be deflected in weeks, while larger asteroids could take months.
