Future Asteroids Could Be Deflected With Nothing But Space-Graffiti

Our planet ’s recent close call with one asteroid , and direct visit from another has by all odds made it seem of import to count how to deflect the pesky thing in the future . One solution is to engineer the Sun ’s power into pulverize lasers , but another selection just involvescovering incoming rock-and-roll with spray paint . elementary as that .

The program , as described by Dave Hyland , prof of physics and astronomy and faculty member in the aerospace engineering department at Texas A&M depart a little something like this : When you see a dangerous distance - stone head this way , you send a especial space ship out to meet it and blast it with a covering of space - spray key . The new coat of key would then impress the asteroid ’s reflectiveness , allowing the Sun ’s Energy Department to catch it just right and send it off a collision course .

If we were to pull this off , there ’d be a few obstacles to over come . First , you could n’t use stock Earth - paint . It could n’t be oil color or urine - base ; it ’d in all likelihood have to be a dry powder , attracted to the rock with static electrical energy . secondly , you ’d have to get to the asteroid early , so that a barrage of photon would have enough sentence to crowd it away . Still , it could be a flashy solution , and NASA has near Hyland about test it . It credibly wo n’t be quick forApophis ’ skinny call in 2029/2036 , but it could be a workable strategy eventually . Now someone reach out to Banksy , and see what he thinks . [ PhysOrg ]
