Humans are justly terrorize by the threat of nuclear warfare , but there ’s also a non - zero chance that a giant rock will come hurling through our atmosphere to ruin every Earthling ’s day . When that encounter 66 million year ago , it spark off a mass quenching that wiped out the dinosaurs . But we have something the dinosaurs did n’t : scientist , who are play heavily to account for all of the dangerous asteroids in our solar neighborhood , and to develop technologies that can move them off a mortal collision course of action .
Carrie Nugent is one of those scientist ; a self - style asteroid hunter whose new TED Word of God offers a brief and entertaining overview of what we know about mysterious bodies that whiz between planets , and put in the world residential area of scientists with a passion for tracking them . Gizmodo caught up with Nugent to chew the fat about asteroid , what it ’s really like to have a daytime job that , for most of us , calls to mind Bruce Willis in a spacesuitdrilling to Aerosmith hits , and what we demand to do to displace a major impact .
In Nugent ’s position , step one toward block the asteroid Revelation of Saint John the Divine is astonishingly simple : We need to encounter a lot more asteroid . Below is a condensed and light edit version of the audience .
Gizmodo : In your view , what ’s the biggest public misconception about asteroids ?
Nugent : I reckon the public perception about asteroid is that they ’re kind of metaphors for acts of God , the fact that we have no control over the universe . They ’re always look as these uncontrollable events . But when you look at the science , they ’re really the exact opposite . They ’re a preventable natural cataclysm , which is just groundless . I cerebrate that ’s the biggest misconception out there . If we were to do a very thorough survey of the sky , we ’d know what was out there [ in terms of asteroid threat ] . It ’s a resolvable problem .
It ’s dead on target that the more we teach about these target , the more the line between asteroid and comet set about to fuzz out . People have discovered asteroids in the Main Belt that outgas like comet , and thing on cometary sphere that no longer outgas — that do n’t have tails . We ’re find all of these unique cases . I call back every time we send a space vehicle to an asteroid or comet , we learn more .
Gizmodo : How did you first become interested in asteroids ? When did you know you wanted to be an asteroid hunter ?
Nugent : It ’s an usual life history . It was n’t like I was a small child dream of this , though I always liked geology and learning about the world . I did my undergrad in physics , and got PhD in geophysics and space cathartic .
I really know [ asteroid hunt ] because it ’s practical , but it ’s also gross natural philosophy and astronomy . It ’s utterly mind blowing to me how precisely we can predict exactly where asteroids are go . Their arena are governed only by gravity , and to a lesser extent sunlight . The military group are very well studied .
Nugent : I suppose it ’s certainly less glamorous . I play in an office building , at my laptop computer all 24-hour interval . That allege , it ’s very fun . One affair I care is it ’s very much a team sportswoman — I’m work a small role in a much large grouping .
Gizmodo : I was surprised to learn that based on NEOWISE study results , we ’ve only found about 30 pct of all the near Earth asteroid majuscule than 100 cadence across . That implies a Brobdingnagian number of large , closelipped - by asteroid we have n’t found ! How before long can we have a bun in the oven to detect them all ?
Nugent : It ’s a great doubt , and depends on what decisions people choose to make in the future with funding . All I can really say is that it ’s of import to receive these matter , and I think we call for to make the investments .
At the end of the script , I talk about how mass think that since we have sent spaceman to the Moon , the region of space between the Earth and Moon is totally research . But it ’s not . Because the Earth , Moon , and asteroid are always moving as they go around the sun , that region of outer space is n’t unchanging . We still sometimes discover new asteroids that pass between the Earth and the Moon .
Gizmodo : You talk about the office science fabrication , particularly Deep Impact and Armageddon , meet in bringing the threat of an asteroid impingement onto the public radio detection and ranging in the ‘ ninety . Do you call back science fiction plays an authoritative role , today , in keeping the world engaged in this kind of skill ?
Nugent : perfectly . I recall that scientific discipline fiction is implausibly potent , a great way to get multitude aroused about space . One example that now fall to brain is The Expanse . What I screw about it is they ’re demo hoi polloi interact with solar system in a marque new room . And now , because of it , people are familiar with asteroids and bantam moons that they were n’t before .
The powerfulness of Armageddon and Deep Impact is also really unbelievable . I can be anywhere — in a coffeeshop , say — and if it happens to come up what I do , people alway bring [ those movies ] up . And it sound annoying but it ’s not , it ’s awesome ! I do this really niche thing , but masses know about it because of Bruce Willis .
Gizmodo : In the leger you discuss all these crazy methods we might utilize to deflect asteroid , like tractor beam , nuclear missiles , and small projectiles . But we ’re still a ways off from any of those methods really being workable . What are the most of import things we need to be doing , decently now , to make ourselves better prepared for a great impact ?
Nugent : I ’m immensely slanted . So I think the most exciting affair is incur the asteroids . part because I suppose it ’s a anteriority right now , that would give us the warning sentence we need to react fittingly . I suppose it ’s so exciting to find them , research blank in that style , and from my laptop . But to be honest , I would get laid to put myself out of a job here because we ’ve see them all .
Gizmodo : Say the Revelation of Saint John the Divine asteroid is on its way to Earth . In your idea , what would the ideal global defense team web look like ?
Nugent : I ’m not a special expert in asteroid deflection . But as I spell in the book of account , asteroid are all very different , it think it ’s good to have a spate of dissimilar choice . I ’m also kind of thankful that I ’d not be the one doing the pick .
