In space, there are millions of asteroids that exist. Well, major asteroids are no harm to us, but few can be. We all know that asteroids, if hit Earth, can bring massive destruction to the Earth and humans ofcourse. In the case, what should we do? Should we destroy those asteroids? Well, the various space agencies including NASA can develop such technologies that can destroy asteroids which pose danger to our planet. But, it won’t.
NASA says it can’t afford to build a space telescope considered the fastest way to identify asteroids that might impact the Earth with terrible consequences.
A 2015 law gave the space agency five years to identify 90% of near-Earth objects larger than 140 meters in diameter, which could devastate cities, regions and even civilization itself if they were to impact the planet. NASA isn’t going to meet that deadline, and scientists believe they have so far only identified about a third of the asteroids considered a threat.
According to a report by Quartz, researchers at NASA’s Jet Propulsion Laboratory, led by principal investigator Amy Mainzer, developed a proposal for a space telescope called NEOCam that would use infrared sensors to find and measure near-Earth objects.
The National Academy of Sciences issued a report this spring concluding that NEOCam was the fastest way to meet the asteroid-hunting mandate. But NASA will not approve the project to begin development.
The agency said it was prioritizing funding for ground-based telescopes looking for asteroids, though the report concluded that they would not fulfill its mandate.
MIT planetary scientist Richard Binzel said, “Although highly unlikely, being taken by surprise by a catastrophic asteroid impact that could have been detected would be an epic failure in the history of science.”
Richard Binzel further said, “We now have a capability to know what’s out there, meaning we have no excuse for an ongoing lack of knowledge.”
Lawmakers haven’t been enthusiastic about funding the lunar return, but asteroid hunting might be an easier sell. A national poll of Americans taken in May found 68% supported missions to find asteroids that might impact Earth, while just 23% thought a return to the moon would be a good idea.
