Haha these cookie popups, I don't know why I'm hesitant to take action on them. So like this site on mobile I'll read the article through half my phone screen.
Many years ago I experienced a VR tour of the solar system on Oculus. I never fully comprehended just how big the sun was until going on that tour. Something about being able to float around in space, and see the planets stacked next to the sun going off into the horizon and looking up and down and all around at the sun, just a really cool VR exclusive experience. Fascinated to hear what they learn from this orbiter.…

Interesting article thx. 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?
The direction is "towards" or "away" from the sun, the only way to get closer to the sun is to make your orbit smaller, the only way to do that is to slow down in your current orbit. You can't reach a lower orbit by accelerating. (I'm simplifying a bit, it's all acceleration, what matters is if it's in your orbital velocity, prograde, or against it, retrograde)
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.

Fun fact, the video changes from a direct video element to a YouTube element if you accept the cookie banner.
The video is only playable if I _don’t_ click the cookie nag.
I love watching video of activity on the solar surface because my brain has no intuition for the immense gravity and plasma dynamics at play. It's almost like getting a glimpse of a world with different laws of physics.
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?

If I were to visit the sun I’d probably orbit it close up, rather than landing on the surface. Seems like the sensible thing to do.

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.

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.)

Yep, that's a word! https://en.wikipedia.org/wiki/Spaghettification

I "hacked" NASA (I used wget/curl to download the publicly available images) to get the specific shots (wavelength/resolution) from SOHO to get an entire 11 day's worth of a single rotation of the sun. We put that sequence into a VR setting. It was strictly for a demo/PoC of an idea we were knocking around. The idea didn't gain any traction with the producers, so it just got shelved. It was fun showing everyone how s…
