There was a previous mission (Ulysses aka International Solar Polar mission) that sent back a lot of data but for whatever reason, they didn't have it send visual images. Big bright ball = no surprise, maybe.
This slightly tilted view of the poles is a teaser. I didn't know they'd managed to incorporate late in the mission gravity assists into the cheaper plan B to slightly tweak out of the ecliptic while dropping close to the sun. That's pretty cool. https://upload.wikimedia.org/wikipedia/commons/6/66/Animatio...
But we could've had so much more. The original proposal A for the ESA Solar Orbiter was a highly inclined orbit relative to the ecliptic plane to truly get full polar views of the sun. But this was too expensive. So they went with the cheaper proposal B which was mostly just a spectroscopic platform. Similar to SDO AIA, except in a solar orbit (almost completely within the ecliptic plane) instead of SDO AIA's Earth based sun synchronous orbit.
It does, but most of the needed dV is harvested from the planets during gravity assists. The probe is accelerated/turned several hundred or thousand m/s and in exchange the planets it passes are shifted/slowed/turned by maybe 0.00000000000000000000001 m/s. In this case, the probe largely needs to slow down, to bleed of the speed it got from being at earth's orbit, so the planets are probably being accelerated.
I love this, seems so minor if not paying attention but it's absolutely mind blowing. Getting a view we never saw of the life giver, an object that used to be revered as a god, nearly every human alive I history has basked in it's light and heat, and the for the first time we are seeing it in full
A nice reminder of how patchy and limited our knowledge is despite the impression of the opposite.
Keep up the great work, humans!
Or better, "humanity's first".

Not sure if 33° angle in 2029 is the final "polarity" or if they'll keep tilting after that.
