WARNING: Don't challenge Dr Meghan Gray to a game of Scrabble - this video is about interplanetary travel and orbits.

Fun fact, when picking a user name for a BBS many years ago I thought of this word I'd read. However I didn't remember how to spell it or pronounce it, so I came up with Szyzyg - which is still my username on a number of systems.
did your BBS end up on any of those big collated lists people used to make? For a while on ebay they would sell these CDs that basically had a list of every resource that had been out there pre-internet. Your BBS name looks familiar.
when I read Syzygy and orbits I was actually expecting to see an interview with you :D
THAT WAS YOU!!
I originally clicked on the video because I thought that you had done a video in collaboration with Sixty Symbols.
Love you scott
1:26 "[The Expanse is] a story that's entirely set within the solar system." So, a bit like Friends, then?
Well, technically... leading up to the last season finale.... That's not true anymore XD
Taricus yeah when ross and rachel reached solar escape velocity, that was pretty surprising
What I find amazing is that there are more 13 to 16 year olds that know exactly what is being discussed here because of the Kerbal Space simulator and Scott Manley who played the simulator on YouTube for several years. He made it as much about learning these things as he made it about entertainment. Kids were learning astrophysics and didn't even realize it. I, myself, at age 65 have played KSP enough to understand the terminology and ideas you are explaining in this video, but if it wasn't for KSP and S. Manley, I would be scratching my head on much of it. In my opinion Scott Manley should be given some sort of prestigious teacher's award for the number of young people he taught in a two or three year time.
Half expected this video to end with "I'm Scott Manley, fly safe"
I started looking for KSP references in the comments at the very start of the video. Was not disappointed. :)
I'm Scott Manley, Fly it like ya Stole it
I thought I was gonna be the only KSP player here. Awesome surprise :D
I had the same feeling.
@Waify SNACKs!!!!
"Maybe that is where they started?" xD
Sindar Rin
Only if the Universe is a simulation, which is actually not that improbable.
"You're troubling me today"!
@heekimsang I think the term used was even "trolling". Brilliant :-)
Crashing a probe on a planet is called lithobraking.😁
Only on planets that have a lithosphere. It isn't called that if you crash into a gas giant.
And with some planets there is even a hydrosphere to consider.
@Kenny Phillips Those sudden attacks of gravity can be expensive... 😏
Just did it on Dres.
Spirit and Opportunity did this with Balloons 🎈 didn’t they?
I mean aerobraking was also used but the final stop was several bounces apparently.
Very droll
When I saw the video title, I thought, "Oh boy!" - but a minute into watching it, I thought, "Hohmann!"
haHAA i see wat u did there
It is obvious if you think about it. The minimum energy for a transfer orbit from Earth to Mars, Jupiter, or whatever, is the doubly tangential orbit. Tangent to Earth's orbit and tangent to Mars's orbit. Clearly no other orbit could use less energy.
This pun has me Oberth a moon
I'm going to change my facebook occupation to "Participant in the Kerbal Space Program". Dr Gray is the best!
Hey - only 2 Y's in Scrabble!
got 'em
There are also two blanks.
And only seven-letter words are highly valued competitively, most times. Maybe syzygy would cut it against some weaker seven-letter words with the Ys and the Z but.
@Kaitlyn L sevens are great, but z and y are fairly high point tiles. Depending on how it was placed, could be worth a lot. Better yet, syzygies, which at 8 could triple triple, and land the y on a double letter. This would score up to 302 points for a single play.
Nerd.
Came for The Expanse shoutout, stayed for the rest of the video.
same here!
I'm glad I finally know how to pronounce the name of this X-Files episode.
"The Expanse"
stares excitedly
"Kerbal Space Program"
vibrations intensify
This was a really good introduction to orbital mechanics. Thank you!
"pluto is not a planet"
"I'll let myself out" :D
"Australia is upside down, which I like."
Is it because it puts everyone right side up?
Ketsueki Kumori
It seems to be the wrong way relative to Asia.
Earth is flat! Everyone is equally upright, even Australia!
@jannor321 I perceive it to be my right to have a right... right?
? Then Our Shite Goes Up Not Down ?
@5pecular Up Is The Opposite Of Gravity .
"Pluto isn't a planet"
yeah, that's a mistake that needs to be undone already.
I brake for Hohmanns. It should be a bumpersticker.
1000 <3 for The Expanse... love it!
My brain is sizzling when I hear syzygy
Scott Manley and Kerbal Space Program taught me all of this... great to hear KSP mentioned in this vid... love it!
Learn how to get around using orbits: Just play Kerbal Space Program for a while.
Thank you for "The Expanse" tip.
"Maybe that's where they started" (in a straight line). - Brilliant! :D
I think this new model of solar system formation should be called The Haran Accretion Line Theory.
TIL I've been mispronouncing this word since I learned it from destiny lore.
this video was so good. thanks dr. gray and 'dr.' haran. more orbmech please :D
Syzygy has been my go-to word to use in hangman (paper/pencil word guessing game) since I was in 3rd grade. I read the word in an astronomy picture book and it stuck with me ever since.
If you wanna go Welsh why not use 'crwth'.
@Random Guy welsh name for a cirque
bravo! I'm using this from now on as well
Greek word
@Petra Kann ok
This was a GREAT episode! Lots of interesting info, covered very well. Dr. Gray is great!
WOWW LONG TIME YO
For a second I thought this would be about Grobner bases.
Excellent video on the basics of Syzygy and related,aspects of orbital dynamics. Worth noting that Apollo 13 used a slingshot maneuver to return to Earth.
You could use a blank for the second Y ; )
Meghan Gray loves The Expanse, awesome!
Dr. Gray you are such a pleasant person to listen to, and lovely to see, thank you for all your work and sharing your expertise
Ah, my favorite hangman words of all time.
KSP has prepared me for this
Came because I wanted to learn. Stayed because Dr Gray's a fan of The Expanse.
Scott Manley!!
Awesome video, Syzygy is my favorite word in the English language! :)
What they named a probe that uses gravity to slow down instead of of speeding up: Parker probe
2:21 Nice Rolex Explorer I, Brady! You should've been wearing a Speedmaster for the anniversary of the moon landing, though!
"Dwarf planet" is still a planet.
4:18 Someone else got the snacks reference to Kerbal Space Program
Great explanation!
More videos about orbital mechanics please! My Kerbals need this!
I just knew Syzygy from the Michael Brecker track of the same name!
I'm early
Deep Sky Videos and KSP, the perfect syzygy. 😀
Yay, it's Dr Meghan Gray!
it's my favorite word too.
Another Professor Gray video. That's good news.
Looking forward to watching it in its entirety tonight when I get home.

in fact only 117 of the 255 alignments of planets has had enough time to repeat at least once in the 4.5 billion age of the solar system.
Omesh Singh - 2019-07-21
Jupiter aint got no land to land on.
whiterottenrabbit - 2019-07-22
What about the Foodskey channel? Have you definitely abandoned it? At least a statement would be nice...
Yves Lacombe - 2019-07-24
@Omesh Singh No but you can use jupiter for aerobraking to get yourself into a nice jovian orbit intercepting one of the moons that have a solid surface for instance.

love the animations in this one. Cheers!
