For example, Nasa\u2019s <a href=\"https:\/\/www.independent.co.uk\/space\/nasa-dart-mission-date-asteroid-b2151950.html\">Double Asteroid Redirection Test mission, simply known as Dart, <\/a>used a spacecraft to hit and change the path of an asteroid. <\/p>\n<p>The test required ample time for preparation, however, and it was concluded that this approach could be very expensive.<\/p>\n<\/p>\n<div>\n<figure><figcaption>A TV at Nasa\u2019s Kennedy Space Center captures final images from Double Asteroid Redirection Test before it smashes into asteroid Dimorphos<span> (AFP via Getty)<\/span><\/figcaption><\/figure>\n<\/div>\n<p>\u201cAlthough the recent Dart mission by Nasa demonstrated that near-Earth objects can be successfully targeted, deflecting the most dangerous asteroids will require energy concentrations akin to nuclear explosions,\u201d the lab study concludes.<\/p>\n<p>An alternative approach tested in the new study uses X-rays from a <a rel=\"nofollow noopener\" href=\"https:\/\/phys.org\/tags\/nuclear+explosion\/\" target=\"_blank\">nuclear explosion<\/a> to rapidly heat up the targeted space rock\u2019s surface, causing it to vaporise and change course. <\/p>\n<p>In lab experiments, the scientists tested ways to mimic the effect of a nuclear device impacting an asteroid.<\/p>\n<div>\n<figure><figcaption>Astronauts report Boeing Starliner is emitting strange sounds<\/figcaption><\/figure>\n<\/div>\n<p>Researchers used X-rays to target two 12mm mock-up asteroids in a vacuum. One rock sample consisted of quartz and the other was made from fused silica.<\/p>\n<p>Scientists observed that the X-ray pulses heated the surface of the simulated asteroids. This caused a vapour plume that generated momentum for the quartz and silica targets.<\/p>\n<p>The X-ray pulse was found to make the rocks move at velocities of about 70 metres per second.<\/p>\n<div>\n<figure><figcaption>Image of an asteroid destruction<span> (Elena Khavina, MIPT Press Office)<\/span><\/figcaption><\/figure>\n<\/div>\n<p>Researchers used this data in simulations to assess how this method of asteroid deflection could scale. The findings suggest that near-Earth objects with a diameter of around 4km could be deflected with the nuclear impactor strategy.<\/p>\n<\/p>\n<p>\u201cWe scale these results to proposed interceptor energies and predict that asteroids up to a diameter of 4km can be deflected with this mechanism, showing a viable way to prepare for future planetary defence missions,\u201d researchers say.<\/p>\n<p>Scientists call for future experiments to investigate other target materials and structures. They hope to test different X-ray pulses since the vapour plume generated by them is dependent on the targeted space rock\u2019s chemical composition.<\/p>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<p>\nFuente: https:\/\/ift.tt\/KTchQEi<br \/>\nPublicado: September 23, 2024 at 11:11PM<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Your support helps us to tell the story As your White House correspondent, I ask the tough questions and seek the answers that matter.
