38:38>> But that being said we will move into the rundown. Uh it seems like the audience likes a little quick rapid fire. So again the concept of the rundown we can't cover all frontier science research in the level of detail we do. We would be here until the end of time. But it is still important to know briefly what's going on in the world around us. And we're going to start with our first round rundown story from January 8th. The hidden strength of iron asteroids. This is a planetary defense story. The obl of space. Why iron asteroids are harder to deflect. The by line on the story is a groundbreaking simulation reveals that ironrich asteroids possess a hidden stren
39:19strength that makes them more resilient to impacts. than previously theorized. This is out of the University of Oxford and CERN. And the implications here are using CERN's high map facility, physicists irdiated meteorite samples with high energy proton beams to see how they would deform under stress. Yeah. >> They discovered that there was this dampening, meaning that the faster the asteroid is hit, the better its internal structure dissipates energy, which is a little counterintuitive. So this just suggests that kinetic impactors like the idea of NASA's dart mission which I believe was to like intercept shoot something intercept an asteroid on on its way in.
40:00>> Yeah. So intercept an asteroid and change its trajectory. >> Yes. Yes. The idea is um that it would remain intact because it would be able to uh dissipate the the asteroid would be able to dissipate the energy on impact. >> Exactly. we wouldn't have like an Armageddon situation um where the asteroid would break up into a bunch of chunks and then now instead of worrying about one thing, we're worrying about nine things [laughter] that are coming in. Um
