How do we get spacecraft out of orbit? Neil deGrasse Tyson and Chuck Nice break down everything you need to know about deorbiting spacecraft and safely reentering our atmosphere. How are we going to get the ISS out of orbit?
Learn about terminal velocity, escape velocity, and how aerobraking heat shields save fuel. We discuss issues with uncontrolled orbits and crashing into the Pacific Ocean. Plus, why did we let Casini burn up in Saturn’s atmosphere? How are we going to get the ISS out of orbit? Neil also shares his ideas about the new space race and China’s space station.

As someone who hated rote memorization, the multiplication table is 'fuzzy' around the mid 6's and 7's. So, I actually came to the correct answer at about the same moment Chuck did. I do think he missed a comedic opportunity to echo Neil's frustration, when Neil says "49 is twice 25."

Always great to see Neil using his office, at the Hayden Planitarium as a set . So many interesting books and artifacts just out of focus. Would be great if when filming from his office that Neil shares some info on the books on his shelves. Ideally, one title every time he post a video from his office, but even a Book of the Month would be great. Books are awesome, they don't need batteries and totally impervious to solar storms and any other forms of electromagnetic interference. Please share !👍👍👍

@StarTalk , im glad and appreciative of Chuck touching upon a subject that almost no one talks about. I understand this is the primary channel , but I do believe having a podcast about mental health in general would be a great subject for your secondary channel Startalk +. It's not everyday that astrophysicists come out and openly talk about their mental health. Chuck I appreciate you.
It's nice to listen in on you guys. Love all the information I get . Thank you.
Beautiful, just beautiful conversation.
Don't know about Chuck and Neil, but I think most of us learn "two and two make four" even before we learn that E = mc^2. Fight me on this one.

@@vanshamb ur not wrong; I think Neil was just going for the low hanging fruit that the common undereducated American would know, even if their understanding of it is closer to E = MC Hammer. The kinetic energy formula is precisely what engineers use for spacecraft kinetics. The kinetic energy formula is part of General Relativity, and in non-relativistic cases GR reduces to KE. The mass energy equivalency is what Special Relativity reduces to for speeds that are not a significant fraction of the speed of light. They're both parabolic equations that fall out of hyperbolic equations.

Chuck was right with 42. It’s the answer to life, the universe, and *everything*.
Considering the cost of getting all that material up there (that could be re-purposed / re-used) is de-orbiting the best solution though?
Chuck got it right, 42 is the answer to everything. Neil just didn't get the joke.
nice office, very nice ... can you do a guided tour around it some time in the future?
This video is why I don't do math in public... And kinda' not cool to both put Chuck on the spot like that and then shame him rather than just say something like "Not quite, I think it's 49" (or something similar) Lastly, Chuck, thanks for being so willing to share your struggle with depression - that's a very difficult thing to talk about, and, as you said: often a source of shame. I'm glad you found the help you needed and what worked for you!

I disagree. Unless you have a severe learning disability, I think it’s kind of shameful to not know your multiplication tables as an adult. I agree it’s not cool to shame people with disabilities, but in Chuck’s case I suspect it’s probably not a disability, but rather he just didn’t do his math homework in 3rd grade.

@@stevenqirkle Incredulity is not an argument. Just because you can't imagine this doesn't mean it's not a real problem for people who are both not lazy and not profoundly disabled. I recommend you go to google and search for 'reasons people don't remember multiplication tables.' You might discover that human brains aren't just biological equivalents of calculators/computers and not everyone is 'wired' the same. In the same way that some people 'get' spelling and others don't, some people 'get' mathematics and others don't. Or... Continue to disbelieve anything you don't understand or for which you haven't figured out an answer... Whatever makes you happy!

How do you get to substitute other velocity values into the E=MC^2 equation to calculate energy when C (speed of light) is a constant?
Neil and Chuck, y'all rock! ❤Peace 🤘 💥 ✌️
A helpful analogy for visualizing an object entering Earth's atmosphere is to envision yourself in a speeding boat, seated at the edge, with your hands skimming the water. The sensation of the turbulent fluid rushing past your hands, potentially causing harm, mirrors the experience of an object encountering Earth's atmosphere.
I think that it would be very interesting to see a Startalk review&analysis episode of science presented in The Three-Body Problem(the Netflix tv series, the book or both). Maybe Chuck thought Neil asked him what is the meaning of life, the universe, and everything.
When it's time to replace the International Space Station, how feasible would a "take a new module up, bring an old module down" system be? Maybe not for every module, but the opportunity to study what 25+ years of exposure to space has done to the craft
Love the Black Hole lunchbox on the shelf. I saw that movie with my grandpa.
Hi love the show... Any news on the latest observered supernova?
Speaking of Endeavor, it's now vertical on a full launch stack while the new display facility is built around it.

I wonder if its possible to have a cable up to a satellite at 22,500 miles (geostationary point.) And have spaceships crawl up and down? At around 200 miles you could disconnect and fly without all the energy needed to get in orbit and slow gravity to de-orbit down the cable to the ground.

If energy is velocity squared, does energy have a directional component? Or is it actually just speed squared?

I have a question about black holes.. given that black holes take in mass and light cannot escape, would it not be reasonable to say that what happens in a black hole is mass and light being converted into energy? And then once a black hole reaches its limit to contain that energy, it expels matter and light…. And would that then be considered a white hole?
True, true.
great editing! was fun to watch
