Thanks Elysia and the whole NSF team!
Thanks Elysia and NSF team.
Thanks for the weekly update TWiS Team! I really enjoy the breakdown of the weeks launches along with their trajectories and orbits. It's interesting and helpful to see the numbers visualized. The Starlink total running count vs how many are operational or deorbited is always mind-boggling. Plus, guessing what earrings Elysia might be wearing is a fun game to play. I'm typically wrong as I am with most things in life. Keep up the great work NSF and I will keep coming back. Thanks again!
Once again Elysia a great this week in space flight, Thank you!!
Elysia and NSF, y'all rock! Peace
Merci Elysia pour vos très beaux documentaires. Cordialement
Elysia, you always do a great job with your reports. You also have a nice collection of space themed earrings.
Elysia, you are, by a long, long way, the best presenter of NSF. All to do with your smooth, uninterrupted delivery (I don't think you corrected yourself even once) and professional image. Thank you.
Elysia!🎉 Happy Friday NSF team, great work!
3 1/2 minutes of perfect clear sky totality in Island Falls Maine. Almost no traffic issues. Awesome!
Epic! 😎
I'm really excited but my wife's boyfriend keeps calling me a nerd.... how can I prove to him that this 80 year old technology is cool😂
So good to have cameras on Starlink Satellites.
Dang I didn’t realize how iconic this week was! Total solar eclipse, delta heavy last flight… Those are some big events for just one week. We were lucky enough to live in the direct path. It was only a little bit south of you guys though so it was also quite cloudy but we all had such an awesome time and still caught glimpses of the eclipse.
I'll never stop being fascinated with the engineering that goes into rockets. Such an incredible feat of human accomplishment.
We live in amazing times when there is so much space news in just one week!
Very showing of the raptor vacuum engine 👌 👏 👍
Thanks for the run-down of this week. As someone stuck in the UK for the eclipse, thank you for all the excellent coverage. Looked amazing! Looked spooky! Going though the launches, I lolled at "For the 3rd Falcon 9 launch this week" and lolled again cos I forgot there was a 4th. Crazy times! Relentless.
Another great update from NSF!
Awesome content as always, and of course…the earrings 👍👍👍👍👍👍
I went to Rochester (from California) and saw what Elysia and Das saw. Totality is pretty awesome, even on a cloudy day!
Another great broadcast ❤
Love these, another great job, Elysia and team.
Elysia is a boss! Thanks for the awesome recap, team.
I love Elysia Fridays!
Elysia, are those falcon heavy earrings? Incredible.
I love the science content! Anyone who has operated a MAP torch has viewed some of these same principles at a micro-scale. Orange flame is sub-optimum burn.
Thank you.
Great as always thanks ❤
Great coverage, thanks NSF team
6:00 HawkEye 360, "Signals intelligence gathering". In the common language, that means "Spying satellite", tho.
Elysia: Best presenter on YT!!
Wow so much power
Congratulations 🎉🎉
Simply awesome!
The 1999 eclipse was during my brothers birthday party, one kid was running about while everyone else was sitting watching with the proper glasses and that kid ended up with glasses like 2 weeks later and his eyes are like an old man’s at 32 year old and we swears the party incident never happened 😂
Great show :)
Japans Moon Rover is like a Gundam. of Corse🤖
Thanks for the update and views 🇺🇲🇺🇦
The fact that Delta is completed around 700 in 65 years and the Falcon family has 300 flights in a fraction of the time is illustrative of the revolution that Space X started and now includes other companies. This is a new golden age of Space Exploration. We also have the extraordinary programs from India and China.
I love your earrings. You always have such wonderful pieces. You’re doing great work.❤
I didn’t get to see totality here in NYC, but I got to say the partial 90% eclipse was pretty dang close, here only a sliver of the sun was visible while the rest was blocked out, instead of a crescent moon we got a crescent sun and while it did not get fully dark it went from daylight to what its like at the very end of sunset right back to regular sunlight, while not totality it was still very exceptionally profound.
I’m so excited to see the private space sector starting to build space stations! It’s going to be really cool to see what they come up with.
I was in Cape Girardeau, MO, and the eclipse was great. Some high altitude haze, but otherwise clear. The birds kept singing, dogs kept being dogs, but all these humans behaviors changed abruptly. They made weird noises, ran around, and were generally silly.
P.S. I really like the Falcon Heavy and Sun earrings!
Enjoy from Italy
Toyota building moon rover? It will outlive us all.
Just run a silicone seal around all the doors on a hilux job done 😂
Happy Friday
Grew up in Rochester. Apologies to you and Das on behalf of one of the cloudiest cities in NY :|
Honestly the clouded view was well worth it. Seeing the shadow of the moon approaching on the bottom of the clouds is something you miss out on if it's clear. Got way darker, too... like a double eclipse. - Das
Happy Friday.😊
the future is coming so fast the engines are amazing
That launch from Vandenberg was also seen by many people further east, in New Mexico.
Delta Delta Delta, can I help ya help ya help ya😂 classic movie quote from “Nerds”
I love that we need to qualify "land" landings🤣 Who would have thought that droneship landings would be the norm? Certainly makes sense in hind-sight.
Wow
Like and sub before you leave 🖖👾
Elysia just love your tone of voice and english!
The Music and her Voice always remind me of an old N64 Game called Blast Corps. "Let`s get Moving!"
There's more than one ideal fuel mixture... least unburned fuel, most thrust, etc... which ideal did they hit on the engine?
The orange glow from fuel rich kerolox engines is from unburned carbon particles burning when they hit atmospheric oxygen. If you watch a Spacex launch, you'll see the orange gradually diminish as the atmosphere gets thinner, and the exhaust becomes blacker from unburned carbon.
It is mainly from film cooling. What you describe is for the exhaust plume *after* it has exited the nozzle but before that the plume is still orange on M1D. The RD-180 is the exact same cycle and mixture ratio as E-2 but it uses heavy amounts of fuel as cooling for the engine nozzle and the inside of the combustion chamber walls, creating a much more fuel rich environment past the combustion chamber that lowes the temperature of the exhaust which creates the orange glow. E-2 uses liquid oxygen for cooling and little to not film cooling so the exhaust temperature remains high even when several feet away from the engine. You can see the orange effect that you mention doesn't happen until much further away from the engine
That explains the "WHOOOOP!" noise when they shut down Raptors on the ground...
That's the turbopumps which are present on all Raptor engines. That's why you hear the honk even on sea level Raptors (which do not experience flow separation like RVac)
The honk doesnt come from the nozzle but from turbopumps spooling down
With Starship nearing readiness, perhaps Falcon 9 will be retired. SpaceX could license / open source the design to other ( friendly ) ( ITAR ) nations. I think much of Europe ( and others! ) would love to have a capable, low cost launcher under their own control.
Falcon will still be useful for Dragon and Dragon XL missions.
Flow separation = Doughnuts on a rope
With the raptor shutting down video, at what point could it still be throttled back up? Like, if it got down to the pulsating rings stage, could they throttle it back up again?
When rocket companies start having RBG exhaust, I'll start investing.
yessir
“If it’s kerolox it’s orange if it’s methane it’s blue” - Elysia
We will miss the delta IV
Alecia, I Love your earrings! Where do you get them id love some for my self❤❤❤
Elysia not only sounds beautiful, she is also beautiful
Those earrings look pretty 'heavy' 😄
Does anyone know how long a time period that Raptor video was slowed down from?
It was a roughly one minute video and shutdown takes about one second so roughly 60x that it was slowed down
Much appreciated ❤
That must be loud AF. The camera's probably far away on a long lens and still shaking violently
2:38 is this what causes the characteristic raptor honk when they shut down?
That's the turbopumps
Raptor honk
Alex, two opportunities for a Spanish eclipse in 2026 and 27. You know the jig…
👀🔎🚀👍
❤❤🙌🙌❤❤🙌🙌❤❤
And where is the vacumm engine?
These rockets should have flashing plane lights on them as they launch 🚨🚨🚨
Why? Nothing ever flies over them so it would be pointless.
@@minmo2288 just put the hazard lights on them
@@UmmerFarooq-wx4yo no need, since airspace near the path of the rocket's flight is closed off and constantly monitered.
@@hamzahkhan8952 that's a very stupid rejection from you. There is absolute always need for human identification on something giving off a natural after effect. Primarily as it is causing distress & confusion to people on the ground.
@@UmmerFarooq-wx4yo a rocket in flight would be producing flames and exhaust which would allow anyone to know it is a rocket. and anyone who would get worried about one would soon realize, with just a few seconds of observation, that it would obviously be heading away from them and not toward them. also, people who are most likely to see these launches (those who live near launch sites) would be well aware of these events and might be given warnings of such events occurring.
If put solar panels on the moon the eclipse will be back 😊
6:46 National "Reconnaissance" Office, "Payload classified". "Reconnaissance" it's another euphemism for "Spying activities", and "Payload classified" means "another spying satellite". 😂
why...blue flame..like..a..plasma
Your lights looks a bit bright
👍🇧🇷🇧🇷🇧🇷🇧🇷
Common Sense Skeptic
I'll try to watch the video again 'cos I did not understand a word 😮. I was too focused on the commentator! 😊
7:05 Orion signals intelligence gathering satellite, "a big satellite with a big antenna, that listens from other satellites". OMG, LMAO... That means "Spying satellite", again! 🤣
Wow first with 4 sec upload haha
Synthetic Aperture Radar. Synthetic Aperture LIDAR. Synthetic Aperture Camera. What are the limits?
UTC,why UTC…..WHY ?
Do you want us to use local time for all launches? Because there are some reeeeeally weird timezones out there
🔱💙💙💙 Слава 💛💛💛💛 Україні
It burn methan not kerosene
which engine?
Raptor burns methane, E-2 burns kerosene
i see 🥸
