When Asteroids Attack! Neil deGrasse Tyson and NASA Explain How To Stop an Armageddon

If pop cul­ture has taught us non-sci­en­tists any­thing about aster­oids, it’s that we should blow them up. From clas­sic video game Aster­oids to the Michael Bay dis­as­ter clas­sic Armaged­don, aster­oids are either ran­dom bits of float­ing debris out to destroy us, or mas­sive malig­nant space tumors hurtling our way to destroy us, which we’re told is how the dinosaurs died out. But, says super­star physi­cist Neil deGrasse Tyson—in Vice’s short video (above) “Blow­ing Up Aster­oids with NASA and Neil deGrasse Tyson”—“We’re clever enough that we nev­er have to go extinct by an aster­oid. We have more choic­es avail­able to us than Tyran­nosaurus Rex did.” Choic­es like turn­ing an aster­oid into space dust? Prob­a­bly not. Turns out, Armaged­don wasn’t entire­ly sci­en­tif­i­cal­ly accu­rate. In fact, NASA shows Michael Bay’s movie to its trainees to see how many sci­en­tif­ic absur­di­ties they can find. The record, as of 2007, was at 168.

So what to do! Well, it turns out that the chances of an aster­oid col­lid­ing with the earth are slim, but still a bit too close for com­fort. As Tyson explains above, there is, in fact, an aster­oid head­ed our way, called Apophis, in 2029. If Apophis goes through a region called “the key­hole,” it will impact the earth sev­en years lat­er. The prob­a­bil­i­ty of this occur­ring as of 2009 is 1 in 250,000. Yikes. Astro­naut Mike Gern­hardt, a pri­ma­ry inves­ti­ga­tor at NEEMO (NASA Extreme Envi­ron­ment Mis­sion Oper­a­tions) is on the case. His team uses under­wa­ter sim­u­la­tions in Key Largo, Flori­da to recre­ate an aster­oid-like envi­ron­ment and explore it, col­lect sam­ples, etc. in what NASA calls an “Ana­log Mis­sion.” Just how any of this might pre­vent an aster­oid from destroy­ing the plan­et escapes me, to be hon­est (and the “blow­ing up” part of the video’s title doesn’t ever get an expla­na­tion). But the NEEMO project is still pret­ty cool, as you can wit­ness in an inter­view with NEEMO Mis­sion Man­ag­er Bill Todd below.

The Vice video is part of their Moth­er­board TV series, which informs us on its site that NEEMO, like every­thing cool these days, is like­ly to be defund­ed. Let’s hope they can fig­ure out how save us from aster­oid Armaged­don before the mon­ey runs out.

The Final Descent of NASA’s Mars Rover Curiosity Captured in High Resolution

A few weeks back, we showed you the first grainy footage of NASA’s rover, Curios­i­ty, land­ing on the dusty sur­face of Mars. And we promised to fol­low up with high­er res footage when it became avail­able. Well, it’s now online and on dis­play above. Just to recap, the video shows the final descent of Curios­i­ty, from the point where it jet­ti­sons its heat shield to the moment when it touch­es down on the mar­t­ian sur­face. The video was stitched togeth­er with 666 images tak­en at a rate of four per sec­ond.

What Would It Be Like to Fly Through the Universe?

Of course, the ques­tion has crossed your mind, at least once: What would it be like to fly through the uni­verse? Now you can find out.

Accord­ing to NASA’s Astron­o­my Pic­ture of the Day web­site, the clip above offers per­haps the best sim­u­la­tion yet. The ani­mat­ed flight takes you through 400,000 galax­ies (each spot rep­re­sents one galaxy) and brings you to a point 1.3 bil­lion light years from Earth. And that’s just a small slice of the larg­er uni­verse. Miguel Aragon-Cal­vo and Alex Sza­lay (both of Johns Hop­kins) pro­duced the video along with Mark Sub­barao of the Adler Plan­e­tar­i­um using images from the Sloan Dig­i­tal Sky Sur­vey.

On a relat­ed note, don’t miss What the f#ck has NASA done to make your life awe­some?. It will remind you what NASA’s doing with tax­pay­er fund­ing.

NASA Archive Collects Great Time-Lapse Videos of our Planet

Here’s the lat­est video release from NASA, and it’s anoth­er won­drous time-lapse film from the Inter­nal Space Sta­tion. It’s called “Earth Illu­mi­nat­ed.” If you could sit back and enjoy these videos for hours, you’re in luck. NASA has cre­at­ed a web­site — The Gate­way to Astro­naut Pho­tog­ra­phy of Earth — that brings togeth­er all of its images, still and mov­ing. You can find pho­tographs here and time-lapse videos like “Earth Illu­mi­nat­ed” here. Or you can skip to the Week­ly Top Ten sec­tion, where NASA lists the ten most down­loaded images from the Gate­way with­in the past week. Enjoy.

Carl Sagan Presents Six Lectures on Earth, Mars & Our Solar System … For Kids (1977)

The Roy­al Insti­tu­tion Christ­mas Lec­tures for Chil­dren â€” it’s a tra­di­tion that began back in 1825 when the inven­tor Michael Fara­day orga­nized an annu­al lec­ture series for kids, hop­ing to instill in a younger gen­er­a­tion a love for sci­ence. Almost two cen­turies lat­er, the tra­di­tion con­tin­ues. Emi­nent fig­ures like Sir David Atten­bor­ough and Richard Dawkins (watch here) pre­sent­ed lec­tures to young­sters in 1973 and 1991 (respec­tive­ly). And the great astronomer Carl Sagan took his turn in 1977, offer­ing six lec­tures on our solar sys­tem. The first two talks offer a broad overview of the plan­e­tary sys­tem, set­ting the stage for three pre­sen­ta­tions (see below) ded­i­cat­ed to Mars, a top­ic that holds spe­cial inter­est this week. With NASA just hav­ing land­ed its rover Curios­i­ty on the sur­face of Mars, it’s par­tic­u­lar­ly inter­est­ing to watch Sagan talk about the knowl­edge gained from ear­ly NASA orbiters, par­tic­u­lar­ly the Mariner and Viking mis­sions. In a rather time­ly way, Sagan’s lec­tures put the Curios­i­ty mis­sion in a grander his­tor­i­cal con­text, a deep­er his­to­ry of space explo­ration.

Sagan’s talks assume no spe­cial­ized knowl­edge and run rough­ly 60 min­utes each. You can find more Christ­mas lec­tures on the RI web­site here.

Watch the Descent of Curiosity in Stop Motion Animation: The View from the Mars Rover

The Mars rover Curios­i­ty car­ried a Descent Imager (essen­tial­ly a glo­ri­fied HD col­or cam­era), and accord­ing to Planetary.org, it start­ed shoot­ing images at a rate of 4.5 frames per sec­ond upon its descent. We’ll even­tu­al­ly get access to high-res images (1600 by 1200 pix­els). But, in the mean­time, Curios­i­ty has already beamed back 297 thumb­nail images that have been stitched into a stop ani­ma­tion video, giv­ing you anoth­er look at the dra­mat­ic land­ing. The action starts with Curios­i­ty los­ing its heat shield and ends with it touch­ing down on Mars. How cool is that?

Video: The Minutes Before & After the Landing of the Mars Curiosity Rover

NASA’s Mars rover, Curios­i­ty, land­ed just min­utes ago. If you did­n’t catch the action live online, you can watch a screen cap­ture of the moments before and after the land­ing. The land­ing itself takes place around the 5:40 mark, but the ten­sion in the mis­sion con­trol room begins in the min­utes before that, when the rover passed through The Sev­en Min­utes of Ter­ror. The joy, the tears, the great sense of accom­plish­ment, the first images from Mars (around 7:30 mark) — they all fol­low. A job well done. A great plea­sure to watch.

If you want to focus on the pride in the mis­sion con­trol room, you can sim­ply watch the video below.
