NASA's Dawn Mission (live public talk)

[@lostpony4885]

As a child of the 70s we had only Viking and Voyager, and i had to grow up before any new data would be coming. The time for missions was an entire childhood, and now we have such a wealth of these newer completed missions and watching videos like this one really has me choked. It's really happening! And it's just so amazing, thank you all so much for this.

[@wizzardofpaws2420]

Marc never gives a boring lecture

[@stratolestele7611]

What a great presentation and presentER. Great sense of humor!

[@FabienBoune]

It is my favorite NASA mission so far and the presentation WOOOW !! 100/10

[@do00]

What an amazing speaker. I'm in awe. Pity therealways must be at least one persone botching the Q&A session by wearing blinds and missing the point entirely, but I guess it's unavoidable. Dr. Rayman handled it handsomely, anyway.

[@jimparks3rd]

It warms my heart to hear Dr. Rayman tell his stories and bring the subject of space exploration to life. I have known Dr. Rayman for more than 50 years, and he hasn't changed much. Still a bright and shining star in the constellation of brilliant men and women in the STEM fields of endeavor. The stories he tells about Ceres and Vesta are engaging and approachable so that we can all join in the thrill of travelling through space and time to explore beyond our self-set limitations. When I think back to when he and I were in high school together, he still had the dry sense of humor and confidence in his knowledge of his subject matter. The only difference now is that he has many more tools at his disposal to explore the universe. That would be satisfying if he were just ineterested in learning new things about our universe. Dr. Rayman's gift is an ability to be enthusiastic and informative about sharing his knowledge and wisdom to the rest of us.Thank you to JPL and the total NASA team of scientists to advance and share the rare talents and genius of my dear friend, Dr. Marc Darrel Rayman.

[@lakemanson8051]

I was proud to be apart of this event while it was streamed Live. The main speaker was amazing to listen to as well. seems like a cool guy

[@ianbcnp]

Good stuff - really enjoy NASA's longer videos where you can really get some understanding and depth compared to the plethora of very short videos which I usually find frustrating. A long presentation on both Curiosity and New Horizons would be lovely too.

[@InfoSopher]

Unbelievably great presentation. The guy should be a public presenter for NASA! :D (Seriously.)

[@larrykennedy8867]

Marc Raymond does an excellent job of explaining concepts in a straight forward, simple way. He could have a great career in science education, as if he needed another. His blogs at the NASA pages have always been entertaining, as well as informative.

[@jari2018]

Yes nice talk , enjoyed this .

[@zapfanzapfan]

I like the really long Q&A-session. Great lecture also.

[@dvs.4everfugitive402]

4 years later and im Just finding this.

[@Aszod96]

This Marc Rayman guy is really cool! he should host all nasa talks

[@georgejones812]

Wow this guy has a lot of knowledge. Very very insightful!

[@MaryLinnCrouse]

Excellent presentation! Thank you for this.

[@Nevitar470]

Awesome presentation, funny bits in there too.

[@jozseforgovan8621]

Agreed totally igorigor-they are very intelligent and posessing extreme knowledge-love this performance very satisfying the way this gentleman is explaining NASA big work to get there and show the hard work of a wonderful result -i was anxious to see what are these two spots on ceres really. Love this program.

[@rustycherkas8229]

Informative, and... What a great presentation! Kudos to Dr. Rayman...

[@KarbineKyle]

I remember seeing this streamed live! Dr. Marc Rayman is an amazing planetary scientist who has so much passion! I'd love to see more lectures and talks about Ceres, Pluto-Charon, and other worlds in the Solar System! It's hard to come across a great video with the correct date and an accurate title. You have to wade through a lot of conspiracy theory crap, clickbait videos, and inaccurate videos. I'm so glad when I find one on actual science! Thank you for uploading this! I live for this kind of stuff!

[@InfoSopher]

Maybe not quite what you are looking for, but are you familiar with the Planetary Society's podcast? I love it.

[@KarbineKyle]

No, this is what I was looking for. I wanted to see it again. Also, I became a member recently with the Planetary Society.

[@cmdrbobert9862]

I'm excited to see how else the Ion propulsion technology will be utilized in the future with other craft.

[@derekfagan8508]

Wonderful speaker well presented, fantastic job. Thank you

[@alexanderhammes3134]

Super lecture.

[@praamsaga1727]

Aw, man! I guess I'm about a year and a half late for all of this?..

[@wizzardofpaws2420]

What a great speaker. If anything makes you want to run out and buy the biggest telescope you can afford something like this will do it

[@MizaT11]

The kid at the end, though... So cute! X'D Great presentation, found myself completely distracted by it when I saw it was live :D

[@mikemann2053]

Simply brilliant.

[@mortymcfee7406]

He is a really good speaker, I like him.

[@yogawithcarlos]

this guy is well funny. Amazing lecturer

[@kevinaldcroft6291]

I am interested how they identify the asteroids fragments that have hit earth. The science spectroscopy has identified some of them as coming from an object hitting Ceres. If all of the material in the asteroid belt is the leftover from the creation of our solar system; the assumption is this material is the same throughout the asteroid belt. How can they definitively say these meteor fragments came from Ceres and not other collisions from other asteroid belt objects?

[@Real46]

I agree. Just because a key fits in a lock doesn't prove that it can't fit in any other. And such meteors may have had a very different composition before burning up in the atmosphere and losing the more volatile contents.

[@LarS1963]

Very cool. Great presentation, if perhaps a ~tiny~ bit silly at times. :) Thanks for the upload.

[@harryandruschak2843]

GO TEAM, GO!

[@MichaelReeser]

Educational and entertaining, very funny.

[@ckdigitaltheqof6th210]

37:00 ion is a classic engine, but there is now plasma geothermal & electric burst. If you can get a solar/geo thermal linked with nuclear power, enough to make a craft accel at the range of .05~1.0G force, infinate, you have a increadable gravity grant cruiser in the cosmo's, fossil fuel can still be an emerhency maneuver or takeoff/land. But are not safe in high volume or nuculear mix.

[@JanAagePedersenAtHome]

Great talk! Thanks a lot.

[@rufellajoyevangelista2515]

I have a meteor stone I don't now if it real one

[@anthropomorphicmonster9113]

Wait NASA is still recording videos on tape?

[@Pidxr]

Given the impact-canyon link on Vesta is it at all reasonable to suppose the Grand Canyon might have been helped along by the Gulf of Mexico impact?

[@yttriustelluri]

A quick search says Grand Canyon is *up to* 80 million years old, or as young as 6 million years old. The Cretaceous-Tertiary, or K-T, extinction event is dated at 65.5 million years ago. Doesn't prove your idea right, but also does not contradict it. Apparently the Grand Canyon history is not well defined.

[@SideWalkAstronomyNetherlands]

no...the two have no relation what so ever

[@Pidxr]

Is it worth asking how one would deduce this?

[@SideWalkAstronomyNetherlands]

geology......continental drift, plate tectonics, erosion... the grandcanion is made by a river eating into the slowly rising mountains

[@floupe1]

How could jupiter disrupt the growth of planents when the material is orbiting the sun and some of it was on the other side of the sun?? I think the asteroids are a bi product of 2 or more planets crossing paths and collided.

[@SWAMPJUNIOR]

+floupe1 Because space brotha. Miracles never cease out there, or perfectly defying the odds impacts, whatever the words they rotate are

[@tomvanaarle2622]

Jupiter is ALSO orbitting the sun, it would only have to travel at a minute difference in speed to completely wipe its entire orbit and disrupt practically anything outside it

[@Real46]

Good question! I'm not very fond of that explanation either. Some theories even say that Jupiter originated in another place of the Solar System and only later moved to its current position. They also appear to forget to consider the orbital shifts on Vesta, after the impact that created the huge crater. It must have been located in a very different position before, maybe even much closer to Earth. And since the impact was on the south pole, and now it is in the same orbital plane of the other bodies of the solar system, the original orbit must have been outside this plane.

[@TheEdsta01]

I wish I could travel to the stars.....I would give my life

[@DogsaladSalad]

tie fighter in the thumbnail image. nice.

[@MrPapamaci88]

1:07:14 ...and THIS is why we need the nanotech guys to pick up the pace and produce those batteries they've been theorizing to be possible with carbon nanotube-based electric systems. If I recall correctly, that kind of battery would be like if you changed your cell phone's battery to one with that tech of the same size, it'd last months, maybe years instead of days. It'd also be super light-weight. It might actually improve our chances to make high-speed

[@MrPapamaci88]

Too bad it's still too hard to make mass production possible.

[@damingoflave]

Great video. This guy is hilarious.

[@dalecarpenter8359]

The asteriod belt looks like a destroyed planet ?

[@alphaadhito]

I just know that Dawn was sponsored by Pizza Hut :'D

[@tango_down1554]

I thought it was Comet Pizza..lol

[@kingpencowboy7977]

wonder when after countless billions of dollars are spent they would have thought to share and attatch multiple cameras and stream the video with us or record the flights from external to give us a actual view instead of computer generated pixs as well as video ? I'd love to witness the video outside of mock ups

[@elcompaluis9801]

I wanna go to Pluto Im 3878

[@gjsterp]

Only 44,000 views? Maybe space exploration doesn't appeal to everyone? With so little public interest and support, one wonders why and from where does NASA get so much $upport to tackle these missions, when the information gathered is of so little reliance to 99% of the world population? There must be some people who plan to use this information in a practical way and maybe make a buck in the very NEAR future!

[@danievdw]

Sadly it seems the important ones suffer from gyro wheel issues. Keppler comes to mind.

[@honeydew5022]

Dawn!

[@csmith9684]

=Caution= going through the comments there's a flat earther amongst us.....

[@markgarin6355]

And a functional proven designed gyro wasn't used? Why is that area of the solar system different? Cause of all of the asteroids..ha NASA...not another silly assumption...

Electric universe is a fraud. He never get straight to the point just like ca voodoo guy. He's preaching like a priest, not telling the truth.

Disgusting waste of money. Do something useful with our work hours.
