I believe New Horizons took about 9 hours, from launch, to cross the Moon's orbit, giving it the fastest Earth departure ever.
I suspect Parker may have exceeded that, but can't find the relevant facts -- any ideas? I was looking for the trajectory views using NASA's Solar System Simulator, seen here for New Horizons : Where is New Horizons? But the same thing does not (yet) seem to be up for Parker. |

According to Jonathan McDowell, it was a lot faster (see this tweet: https://twitter.com/planet4589/status/1028699688889933824 .)

Bit surprised at the quality of these since I thought all the cams were designed for far higher light levels. Pleasantly so, though.

WISPR looks for plasma coming off the Sun, so it's not too surprising it's a decent dark-sky camera.

Maybe it'll get really lucky and find some Vulcan asteroids! Looks like STEREO searches have removed chances of anything larger than ~6km. Remember that if one considers the length of the mission, we might get a sungrazer comet near perihelion. The unique angle of observation (and distance) would provide valuable science when combined with observations at 1 AU. Though there's no dust sensor onboard, so no direct way to see if it passes through any of their debris streams? |

Maybe dust impacts could be detected via attitude control.

That's crazy fast. What was the next quickest launch to planetary flyby?

There's discussion of that upthread.

Probably one of the previous Venus missions, I think. No other planet gets that close to Earth, and I think we discussed it up thread!

Parker has completed its first solar close approach. Apparently it has been sending back "all is well" tones.
