Fascinated to hear what they learn from this orbiter. We're currently in the deepest solar minimum of the space age, so I wonder if they'll discover anything related to the mechanisms that drive them.
Many thanks to anyone at NASA/ESA/JAXA/anyone else that makes all of that data available!!

Looks distinctly not part of the corona, more like a pod of some sorts, and it also jitters around in the video. I'm puzzled!
...of course the temperature and hydrogen composition make it pretty different :)
Being in orbit, I would sense weightlessness while being in the presences of an enormous gravitational field. Just as in orbit around earth: gravity is still there, you just can’t feel it.
Would I notice anything different when weightlessly orbiting something 300,000x more massive than earth?
Yes, due to tidal forces being stronger at one end of you than the other. You could use the formula given below but it looks like about a quarter of a newton.
One other thing: not sure you could "land on the surface" because it's all plasma. Flying through it might be interesting.
Yep, that's a word! https://en.wikipedia.org/wiki/Spaghettification
The video is only playable if I _don’t_ click the cookie nag.
Probes bound for deep-space destinations like Mars can piggyback off Earth’s momentum to fly faster. For a spacecraft to launch toward the sun, on the other hand, it must accelerate to nearly match the Earth’s velocity—in the opposite direction. With the planet’s motion essentially canceled out, the spacecraft can surrender to the sun’s gravity and begin to fall toward it. https://www.theatlantic.com/science/archive/2018/08/parker-s...
The answer is somewhat simply that it burns real quick. These guys made the heat shield for this thing and have some decent insights: http://enbio.eu/solar-orbiter/
I'm sorry. This just annoys me so much. There's two perfectly good words that pretty much always should be used instead of "revealed": "Published", or "Announced".
EDIT: Tried also on Chrome. Accepted only essential cookies. No youtube. (Chrome also has uBlock Origin installed, though I don't know how effective that currently is.)

Also, it's what my co-workers called it. These are non-coder types, and can operate a computer just well enough to use the software they are trained to use. I use the Homebrew color scheme in Terminal, so green text on black background. Only hackers use Terminal anyway, so 1 + 1 = ? (you better have said 10)
I dont get why the speed up works only towards the outer solar system though. Why does it have to loose speed to control direction?
Notice how the probes orbit gets more eccentric but still smaller each time it approaches a planet on the left. The gravity assist is slowing it down, again in the solar reference frame.
Ah thanks this made sense. I guess if I was spinning something on a string I would have to slow it down for the orbit to shrink.
It will take 7 passes of Venus though.
The reason that PSP isn't taking these images despite going much closer is that it doesn't have a camera for imaging the Sun.
Basically, using a flyby to apply retrograde speed is not much more than accelerating prograde and then using the gravity of a planet to A) move your orbital position without a speed change and/or B) redirect your acceleration.
