Thank you for giving credit to Chen-Wan Yen. She doesn't even have a page on Wikipedia yet made the exploration of Mercury possible.

"Every single one of us is in this picture." I loved seeing the human race's most recent family photo. :-)

Messenger is one of my all-time favorites, because of how magnificent and audacious its flight plan was.  You can't get there without including relativistic effects, so the fact that the plan went almost perfectly is proof of the value of the rigor of science.

One point I'd like to add: The reason why Jupiter has been visited by so many spacecraft compared to Mercury is because of its use as a gravitational slingshot. Ulysses, Cassini, and New Horizons all did not have Jupiter as a primary target, but only for a gravity assist.

It's amazing how much an atmosphere impacts overall temp.<br>You'd think being so close to the sun the surface its self would get so hot it'd retain heat on the dark side. But it doesn't, in fact it seems to immediately lose the heat.<br>It baffles my mind to think about those extremes switching so fast

The MOST interesting thing about Mercury that you forgot to mention is the Charged Particle display on the Mercurian nightside.  A constant rain of glowing charged particles from the sun can be seen as a psychadelic display from the nightside at surface level as they streak around the Mercurian magnetospheric  bowshock to go trailing away from the nightside.  To an observer on the nightside surface, this would be a mindbending sight

I was told in school that mercury was tidally locked which is what they knew at the time I guess. Thanks for clearing that up.

It sounds silly, but I feel sad for the probe that crashed into Mercury. It's got to be hard for NASA to say goodbye to their "kids" like that. I know people must get attached to them if I can just hearing about its journey.

MY DAD WORKED ON MESSENGER Y'ALL I HAVEN'T EVEN STARTED WATCHING YET BUT I'M SO PROUD BECAUSE HE'S LEFT HIS MARK ON HISTORY IN SUCH A COOL WAY. <br>Screaming aside he worked on his instrument for it (the company he worked at was contracted for a piece and he designed it, he wasn't part of NASA but he made really good friends there including a guy who is basically my uncle in spirit) the month leading up to my birth, so I grew up as messenger was going around Mercury and he got commemorative pins for my family when it got decommissioned and dropped into the side of Mercury. Something intertwined with my life is now part of something that will last far beyond me, to the extend that its melted and become part of the planet

What a wonderful story. The amount of research and planning to make such a magnificent informative video like this must have been massive. I have never seen such depth of information in any video I have ever seen. You are now a Master of Documentary....thank you so much

I clicked on the video just to have some background noise, but I ended up stopping everything i was doing to really watch and listen and now craving for more. Really well pieced together. +1 subscriber.
