- Parker Solar Probe has made 3 flybys of the Sun within 25million km, and is due to get even closer in the next 2 months. The first major results from the probe have started being published with 4 major papers in this week's issue of Nature. So here's a summary of things we've found, new features in the solar wind, new smaller flare events, observation of the transition from rotating to non-rotating wind. And a first observation of the dust free zone near the sun.
Nature summary of the results.

It's nice to hear some positive corona news
I used to have a job gathering data from tools near a drill bit on an oil rig. Wed use that data to steer drilling to get to the target and avoid obstacles like old wells and lease lines.we would watch space weather because a solar flare could effect our azimuth readings a few degrees and we would have to correct for it to maintain course.i always though it was cool that space weather affected drilling operations a couple Kms under the surface.
That is really cool, as a roofer i live with the waves 😆
Just curious? Were your instruments above ground in Faraday cages? I think the readings were not variations below ground except the drilling rods acting as antennas tied to the end effector shielded instruments in the bottom of the holes but variations of the instruments above ground due to the lack of proper shielding?
@@glloydphilpott9630 depending on how much iron was in the formation or of a solar storm was predicted we would bring geo survey equipment. That stuff would be used to calculate offsets for azimuth. Usually though, we would just keep track of the weather.
Proof that everything has gotten pretty dang complicated. That’s crazy cool.
@@Iwoodlikethat you needed to praise the sun so that your drill would not steer and destroy everything 😅
I'm just glad they resisted the urge to name it Icarus.
I mean Icarus dies and they don't want the probe to die too early so...
daedalus made it though
Then at least theyd have the Icarus 2 to fall back on...?
Be glad they didn’t name it “Covid” also!
There was already IKAROS (Interplanetary Kite-craft Accelerated by Radiation of the Sun, IIRC), a Japanese solar sail-testing spacecraft.
Ah yes, the sundive maneuver. A classic which none of us have accidentally recreated in Kerbal Space Program.
Disaster Area's stunt ship sundive is a big part of their show
"Disaster Area are a plutonium rock band from the Gagrakacka Mind Zones and are generally regarded as not only the loudest rock band in the Galaxy, but also as being the loudest noise of any kind at all. "

You need 200K m/s delta v to reach the surface of the sun in ksp...
Burning 200k m/s in ksp is not accidentally possible...
@@adamsrealm Alternatively you can get a few assists from Jool. At least that's how I've ended up very close to the sun.
@@adamsrealm Only if you want to land. It's very easy to boost your orbit far out into space, and then kill your velocity. Which essentially makes you fall to the surface of the sun.
I think this probe has earned the right to wear sunglasses at night
We're on a mission from God.
What do you mean by 'night', exactly?
It doesn’t need sunglasses where it’s going
All of these comments are valid in very different ways
This comment wins the internet for the day!
They probably added the Sun's symbol as O to ISOIS because without the O it would be... umm...
Sun terrorism
As in OH SHIT ?
The name of an Egyptian goddess?
... the ancient Egyptian goddess of magic, fertility and motherhood, and death, healing and rebirth. First daughter of Geb (the god of the Earth) and Nut (the goddess of the sky) born on the first day of the first years of creation.
And we don't want to get a reputation for throwing perfectly good goddesses into the Sun, now, do we?
... a great post-metal band.
When I was in High School I helped work with the ISOIS EPI-HI team. I have still never gotten over the fact that I have literally touched something that has gone so close to the sun. Also I remember I was working there when they were in the transition to adding the "O" to the ISOIS since the program was created years before ISIS was a thing.
Very cool! It's worth noting that Isis was a thing in ancient Egypt: A goddess. Our society should really get over that weird idea that words are spoiled once someone uses them for something bad. Back in the day the Nazis used the term "Endlösung" (=final solution) referring to the annihilation of jews. To this day people in Germany tend to frown when you discuss a problem and try to propose a final solution. Is that funny or sad? Yes, yes it is.
Get over it, you are not that special. There is always someone cooler and better than you. Like the dude who actually made the instrument.
@@fitnesspoint2006 Thanks for reminding everyone here that even on this channel CZcams seeps in.
@@fitnesspoint2006 yes, we know you're jealous and bitter about the fact that you'll never, ever amount to anything.
What school did you go to? My university never did anything like that.
Thank you Scott for presenting a straightforward science report - without hype or dumbing down. Subscribed.
"Integrated
Science
Investigation of the
Sun. Or ISOIS for short!"
Nice save.
Nice repost
ISIOTS?
why not just isi? its fairly obvious its studying the sun
They could have just used the "O" (which isn't an "O," but the symbol for the Sun)instead of the "S" like ISIO
Why not Integrated Solar Science Investigation?
Its impressive to witness these kinds of events, even if it is on youtube, but everytime i see stuff like this I feel like humanity is such an insignificant footnote in the grand scheme of the universe its both fascinating and dreadful at the same time.
I love science and space man :)
To me it's no different than how my own life and struggles are insignificant in the scheme of history of just my city, let alone my state or nation. And how the internal politics and intricate historical details of my country are insignificant in the grand scheme of current international relations, let alone the story of humanity as whole, since it's origin.
@@psd993 indeed, and if something small always plays a part in some bigger scheme then, when does it stop? if you zoom out far enough (or zoom in close enough) what would be on the other side? i always recall the original MIB movie ending scene where our galaxy is just a set of marbles for some entity to play with, i still remember seeing that as a kid and it totally blew my mind in a way, as silly as that may sound.
Not to be a buzkill, but that exact stream of thought once led me to attempt suicide XD everything felt so pointless and insignificant compared to the scale of the universe. Such vast amounts of knowledge and answers, that I wish I knew, but alas humanity would certainly not discover in my lifetime, if ever.
The sadness wasn't just in our tiny scale, but especially that we were doing such little to understand our universe. Instead, for example, we spend trillions in advertising alone, just to sell products that end up in landfills.
On the bright side, I didn't die and my mission now is to change exactly this. To make education a priority and prioritise funding on understanding our universe. To accelerate scientific knowledge for the betterment of humanity.
As always good work. I really hope this channel never die.
"That 'O' there actually is the symbol for" not having the name be "ISIS."
Shouldn't they be back to "just" IS / ISIL anyway after getting kicked out of Syria by the kurds and/ or Russians? Last i heard IS...whatever activity had gone back over 90% there... can't be "in syria" if you're not ... IN syria :D
They put the O so they wouldn't get demonitized from copyright
Maybe they wanted to avoid saying something off the cuff like 'we're going to send ISIS to the sun'
Carl Browning I’m all for sending them to the sun or sending an artificial sun to them.
LOL Corbin!
Its nice to see Brian has a fallback if that rock and roll thing doesn't pan out ; )
Yes. Astrophysicists... I know one personally. He works in IT now. :D
According to Wikipedia, he started his PhD in 1971 and ended it 2007. That's a nice limit he sets there for other PhD students...
@@quinto190 he was a bit busy during that time
Its always good to have plan B, the rockstar guitar-god was his. He really tried to be a scientist first, but damn that Freddie, his awesome voice and wicked charisma - Queen suddenly took off like Saturn V and there was no looking back for a while. If Freddie was still alive, Brian probably wouldnt have his degree today. Those dudes wouldve kept going and we wouldve loved it :)
they managed to squeeze like 5 gravity assists in to one launch... holy crap lol
That is rocket science! It all amazes me. I have a difficult time calculating a staircase!
@@vincentconti3633 Wait how do you calculate a staircase?
@@penitentpotato1344 Exactly
Poor Mercury has no pull.
@@penitentpotato1344 theres actually ways to do it.
When building a staircase you must know how vertically you need to go in how much horizontal movement to figure out the optimum amount of step and the size of each step.

@@gordonrichardson2972 well, I've just pointed out funny coincidence.
Personally I'm fine with flashes, strobe lights and stuff, thx.
Scientist in 2015: "ISIS is a good acronym for our instrument right?"
**One Year Later**
Scientist in 2016: "Mate we gotta change this, just stick an O in there and hope nobody asks."
Only because most people are ignorant that ISIS is the name for an Egyption god, no matter what other transitional meaning may have been temporarily allocated to it.
@@melkiorwiseman5234 it isn't that they are ignorant it is that a radical terrorist group used an acronym for their name, and made it synonymous with evil like Hitler did with the swastika. Isis in Egyptian mythology was a goddess of life and magic.
@@melkiorwiseman5234 yeah but the swastika and the nazi salute were also older things from ancient europe and east asia but nobody remembers them for that. Symbols can be hijacked.
All true.
Funny thing, I've read that the swastika which Hitler used for the Nazi party was reversed when compared to the traditional good-luck symbol. If you think of them as pinwheels with a propellant coming from the arms, then the traditional swastika would go clockwise while the Nazi symbol would go anticlockwise.
Considering what happened with Hitler and the Nazis, I'd say that was somewhat poetic. It's like Hitler chose a good luck symbol and reversed it into a bad luck symbol.
@@melkiorwiseman5234 Both orientations were used in a good-luck context in various cultures. It can't be considered "reversed" as some people claim.
That's awesome, I was wondering when we would get to see some of the data that the parker solar probe has gathered. Thanks for the update!!!
One of the main mission objectives is to see if they can figure out why the surface temperature of the sun is about 6000 C, but increases gradually to a few million C in the corona. They think this new switch back magnetic field thing might be part of the particle acceleration. Thanks for the great summary!

Thank you, Scott! I give you bonus points for mentioning Brian May. Rock on!
K.C. Sunshine I saw the reference at 02:57, but the pronunciation didn't click with me!?
Not to be confused with David May, James May, or even Theresa May.
This probe is one of my favourites since it launched and I feel it hasn't gotten enough light (pun intended) ... so thanks for the video! Very interesting to see what comes next.
This kind of videos make me feel so proud, although I haven't acomplished anything myself.
luc key 😂😂😂😂
Wow! Amazing spacecraft, incredible science! Thanks for making this accessible to CZcams!
I've been looking forward to this since launch, thank you!
2:50 I hope the probe doesn't become another one that bites the dust.
Nice one, Roger errrr, Eric
Errr... Brian
@@thePronto I suppose you didn't get it. Not gonna explain it. :-)
@@baskruitnl I got it. Did you get mine?
@@thePronto no. I'm Eric.
Almost at a million subs buddy!!! I will go ahead and say congrats to you.
Awesome video, thank you Scott Manley
Just watching this makes me feel smarter. Thank you, Scott.
I find it so amazing that they set up a course that would interact with Venus so many times. The people that plan these things are freaking awesome.
similar to all the gravity assists for the Voyagers.
Yep, awesome. Planning out multiple gravity assists is hard enough in Kerbal Space Program. I can’t imagine how much work and smarts it takes to plan in the real solar system accounting for multiple years and interactions.
no heat shield would've needed had they sent it at night.
Had they sent it at night the sun wouldn't have been there though.
@@GuidoMakor the Sun would be there, just turned off.
they kinda *did* launch it at night
it'd get fried anyway in the morning, and there's no way we could send it there fast enough

@@almaji666 of course, I stand corrected!
Lolol
What spectacular footage,...and the Parker Solar Probe is just starting its mission. Can't wait for more!
Scott, just want to thank you for obtaining, organizing, formatting, and including such wonderful graphics and putting it all together in such an informative and easily understandable fashion. Bravo!
How scientists decide if they should do an experiment:
Can we make an acronym?
Yes: do the experiment
No: consider it.
seriously, i think having an acronym helps them get funding. like it's one of the things they use to get the senators on-board. of course, i have no proof of that, but i personally like to use metaphors to explain diy projects to the wife, to help explain so she doesn't freak out. she's freaked out in the past when i go into too much detail and she starts zoning out.
Talks about spacecraft flying into the Sun.
Reminds us to "Fly safe."
Well, I've gotten to the point where I like Scott's videos on CZcams before I even watch them. Keep it up!!!!! Someone nominate this guy for an Emmy or something, he really deserves it
Very cool indeed. Incredibly credible.
So many variables. So much to learn that is already known.
Amazing to see such a jewel so close.
this data might be very interresting for future fusion and plasma research :D
Yep
Not really
Its just fascinating what humans have managed to engineer and figure out. :)
Love your reporting. Beautiful instrument packages each worthy of a video.
Such a cool probe and a superb summary. Thank you for the effort.
We are missing the most important paper. How do we use these particles to power out frame shift drives ;)

Even if we cannot live there, I see Venus is good for something...
Great timing to voice, pile of info to digest, thx!
Brilliant video .... your education leaves in awe ........... thank you ... much appreciated..
Thanks Scott, and I really hope you take this as a bit of feedback. I would love to see more videos like this, where you continually update us on recent findings of launched probes/missions etc. We witness so many launches and get caught up in the rocket side of things, we forget and loose track of the actual missions and the science they gather. So I'd love to have a channel to get constant updates of the main, on going NASA and 3rd party science probes sent out!
1:16 I could be watching that simulation for hours
Scott Manly, excellent job! Great graphics, great commentary!
Just wanted to say that I enjoy your videos. This one was particularly interesting because of its currency. It is happening now!
Thank you!.
Surprising really how much dust there is considering the giant vacuum. :)
Thank you, thank you. I will be here all week!
Wait...dust evaporates in a vacuum less than 10m km from the sun? Mr. Dyson...Mr. Dyson...!
@@thePronto And in 2020, Mr Dyson releases his latest creation, The Sphere! Soon to be sucking dust in an orbit near you.
@John Toas 1: It was a joke that you obviously either didn't get or are attempting to troll.
2: Outer space has very low density and pressure, and is the closest physical approximation of a perfect vacuum. But no vacuum is truly perfect, not even in interstellar space, where there are still a few hydrogen atoms per cubic meter. Basically it is about as vacuum as you are ever really going to get.
3: If you still believe it is not a vacuum then perhaps you need to look at some basic space related literature that can explain it better to you.
That probe's future is so bright it has to wear shades
😎
I have been waiting in anticipation for this
Scott, thank you so much, your videos are always so interesting and you make the complicated easy to understand. As always, amazing video. Thanks
Suddenly the sun is a living, breathing thing vs some flat disc in the sky.
Cool! Just watched the video from Goddard about the findings.
The Sun is cracking its magnetic whips at us ;-)
I'm really glad for Earth's magnetic field! The Sun looks so (astronomically) violent close up... 😎
Simon Dellenbach I forgot what the dBs ate but if sound traveled in space the sun roars at us at about 125 dB I think
IIRC the sun roars at about 5 Hz.
I've been so excited for this
I especially appreciate the description of the solar wind switchbacks. Great video
The sun has a kinky corona, nice.
"The Sun has corona"
Oh no
I think this probe has proved that space is not so cold after all
Your presentation on this topic was very enjoyable. Thank you.
Scott, you are one of the best tech CZcamsrs on the platform. Thanks for your hard work!
We've ben studying the solar flares since Skylab had a dedicated telescope on board to watch it safely.
You were supposed to say "The last time I was this early..."
*+Pup314* Much longer than that: For example, see Sunspots, R. J. Bray and R. E. Loughhead (1964) Chapman & Hall (London) and John Wiley & Sons (New York) reprinted with corrections (1979) Dover (New York). This textbook is a thorough review of older work, dating back to pre-telescopic observations. It contains many references, illustrations, tables, details of methods, and extensive mathematical analysis of solar phenomena, including sunspots and flares. According to the book, the earliest record of a sunspot was made in 350 BC by Theophrastus of Athens. The rest is history. :-)
Indeed. I don't doubt they have been observing the Sun for as long as we have been sentient, or sapient. Of course our methods have simply become a little more sophisticated than watching projections or crudely filtered direct observation.
Then, that is what the human animal does. Wonders and contemplates things, then devises ever more elaborate, complex, accurate, reliable, incredible methods, machines and apparatus to further study and learn more.
It is pretty much the reason we are now where we are, speaking.communicating on the Internet, as opposed to hunting and grubbing around constantly for food, freezing our bollocks off for a good portion of what would be a horrendous short life, huddled in a fucking damp cave, dying in agony of some infection in a tooth or some shit.
Astonishing how many people appear to imagine that THIS now is magically the normal and natural state of life., and that to get to where we are took massive learning and struggling, and needs an ongoing effort.
We do not seem to be teaching this important point or lesson these days. I think it should be stressed more often.
If you want to read a novel about how devastating a solar flare could be, check out "Flare" by Roger Zelazny and Thomas Thurston Thomas. It sometimes feels more like a paper than a scifi book, so expect a somewhat heavy, but informative read.
What a fantastic briefing!!!
Thanks for this video Scott - both the science and the engineering are facinating, and you do a great job of presenting it :)

I needed this piece of science news. What a time to be alive when we can see this close to the sun
Very well presented. Nice to see the video so well matched to the narrative! Thank you for such diligent work.
This reminds me of _"Out of the Sun"_ by Arthur C. Clarke.
Also "The Golden Apples of the Sun" by Ray Bradbury.
that was a really cool effect on the surface of the sun at 7:50 where what looked like a ridge exploded and collapsed into a valley. a lot of those were happening during that entire animation, but that one still looked pretty amazing by itself.
thanks for sharing your knowledge and research.
Thank you for your excellent presentation!
Right now on Science Friday they are talking about these results
Someday soon they'll be talking about the discovery of how tiny black holes are actually repelled by massive ones.
Most people don't realize how hard it is to slow down enough to reach the Sun.
Cool name. Does it include making anti-white racists uncomfortable too?
Love that you can see our galaxy in those shots when the craft is so close!! Awesomenesseses.

@D.O.A. i know the physics. But even Solar misdions on Earth orbit were so few we do not have any overlap of thrir data which is very bad for creating a homogeneous time series from them.

Petition to refer to its orbit as “Parker Circles”
The way it swings around the sun reminds me of another well-known Parker:
"Solar Probe, Solar Probe, does whatever a solar probe can..." 😉
Hmmm... We need to get working on square orbits.
thanks for making this video.
8:43 - there’s a nice “little” ripple from the shockwave of (what I can only assume is) a smallish interior explosion. There is a large darker area that makes me think the interior was getting relatively cool then suddenly around when Scott says “the weather of the sun” a big bright ring (again, presumably) of compressing gas can be seen quickly propagating out! Not quite sure I’m interpreting what’s happening correctly as I’m no professional but sure was cool!
By the way, great work, Scott; you always fail to disappoint and I love it
I got to see this prob IRL in the cleanroom when it was in John Hopkins' APL
So did I! It didn't have the heat shield, but the main body was mostly there. I'm still thrilled that I got to see it in person.
Can you imagine? That very same probe is now out there doing its thing.
I love how they put a random icon betwith the IS IS just to stop it from saying ISIS
This video is clear and concise. Yippie!
Thank you for the explanation. I was very curious what this probe would fine.
That's a lot of high-energy particle artifacts in the imagery, quite the hostile environment. I wonder if the lifetime of the electronics on board are a significant factor in the effective lifetime of the spacecraft. Some of those particles are gonna leave a mark! The CCD sensor in scientific imager for astrophotography tends to grow a few more hot pixels year-to-year, requiring ever more dark frames for calibration. I wonder if the sensors they've chosen are "hardened" against that sort of thing?
Yes, they have all of the electronics shielded. As is common for all deep space probes. Although radiation protection was probably the easier part, compared to the thermal protection everything also needed.
You are asking this question after it has already made THREE close (about 4 million miles away) solar passes. What do you think? Derp.
@@Thumbsupurbum Clearly the electronics (and detector) are not completely shielded, otherwise you'd not see the artifacts in the form of "hot pixels" in some of those images. At least with CCD detectors, some hot pixels are just additional charge in the CCD well that are clocked out when the image is read. In other cases, the particular pixel is damaged and starts to accumulate dark current at a higher rate than it did before. Some amount of that can be calibrated out, but that's some additional degradation.
My question was if they expected the useful lifetime to be determined by incremental, cumulative damage to the detector (or electronics), or if some other components or consumables are likely to fail or be exhausted first.
FYI, some scientific imaging CCD detectors are not shipped by air because of the increased cosmic ray flux at higher altitudes and the effect on the detectors.
@@lmamakos Well no shielding is 100% perfect, especially that close to the Sun. Yes, NASA engineers would have estimated the life expectancy for the probe, and made sure that the probe could last as long as the mission requires. This is NASA we're talking about after all, they've got experience doing this sort of thing. The reaction wheels will likely give out before the electronics anyway. (they usually do.)
2:45 What are the odds that a vector would be named after someone called “Poynting”? ;)
"What are the odds that a vector would be named after someone called “Poynting”? ;)" It is cute. :) John Poynting was an important physicist, and a lot of things are named after him (Poynting-Robertson drag, Poynting effect, some lunar craters...).

Good video. I have to watch it a few more times to digest all the info presented.
Excellent, as always 👍
I think the immense perihelion velocity is cool, it's getting closer to the relativistic speed range.
i really don't think so
109 km/s is around 0.036% the speed of light - so not THAT relativistic but it's still the closest we got to relativistic speeds so far, I guess :)
@@Magalter That's 0.036% of the speed of light, but what's a factor of 10 here or there.
I mean factors of 10, when you're talking about the speed of light, get really important lol
Mercury's apparent position is affected by relativity due to its proximity to Sol, just a bit. This vehicle's perihelion is a lot closer to Sol so that relativistic effect will be much more important when it comes to orbital computations.
Damn it, Corona has even reached the sun now. We're all doomed!
Funny you mentioned Soho. I was supposed to be at the launch. My uncle worked on the satellite and my family was invited as his vips. I got into trouble and didnt get to go... one of the biggest regrets of my life...
