Israel's Retro Space Launch System - The Shavit
Вставка
- Опубліковано 7 лип 2020
- The Shavit first launched in 1988 carrying Israeli designed and built surveillance satellites, since then it's launched more than 10 time, with the latest being the first weekend of July 2020 carrying the Ofeq 16 satellite.
Shavit is unique among launch vehicles in that it's designed to launch retrograde to avoid dropping spend stages on Israels neighbours. - Наука та технологія
Amusing. Considering Hebrew is written right to left it makes sense their rocket goes that direction.
Hahahaha
Both Hebrew and Yiddish.
@@rwboa22 And Arabic
@@limiv5272 And Persian :-)
כן. עלית על הסוד שלנו, זה הסיבה (use translate. It actually means something)
For anyone wondering
Ofek is the hebrew word for horizon
Shavit is the hebrew word for comet
Seems legit
I knew there was something I forgot....
@Adi Adiani
How will they pay for it?
@@moreno4821 That's an appropriate response. That comment does sound stupid.
I was thinking Vauxhall Shavit
How’d you get your satellite in to orbit?
“I just Shavit really hard”......
Yes, that is the comment we need 😄
Sometimes you just have to go, "Ofeq, let's Shavit into orbit."
He'll be here all day folks.
If you think can just put something in orbit you can go Shavit
oy vey he knows our sekrits.
The geopolitical limitations on their space programme are pretty interesting, I never really considered those.
I think its safe to say that South Africa's space exploring days are over.
Well, they probably could create a ship based launcher and launch form the middle of the Atlantic.
@@movax20h That would be a really cool thing to see. I hope that if they do that we'll get to see some fo that action :P
Duckimus Maximus they’ll probably just hire commercial companies
@@movax20h
I think they aren't going to go with any system working outside of safe(-ish) boundaries. For the same reason, and others, I don't agree with Scott's 747 launch proposal. That's a lot of 'interesting' countries to fly over just to launch east. If I were to do that at all, I'd fly to the West end of the Mediterranean, circle round and launch back east over the sea again.
3 solid rocket boosters with spin stabilization is so beginner Kerbal :P
No spin stabalization sas stabalization
Mechanically simply, easy, reliable. Adapted from or into various kinds of ballistic missiles. Very handy dual use tech, in case the Temple falls again and the Israelis need to teach someone a lesson.
@@noecarrier5035 The Temple hasn't been rebuilt and I doubt it will. Fact checking isn't that hard
Sometimes basic is best, and I think this is one of those instances.
@@limiv5272 Pretty sure that's a metaphor for Israel itself. They literally have a "Samson Option" which is code for retalliation with nuclear weapons during an unwinnable conflict. Whatever happens, the "temple will fall" and crush their enemies with it.
On a road trip deep into Mexico for the eclipse of 1991 I awoke one AM just before dawn and watched a satellite in a low inclination orbit travel from East to West. I knew who's satellite it was.
*whose
1 am just before dawn? How does that work?
@@StephenJohnson-jb7xe Ha! Yes, one morning. Just before dawn.
@@StephenJohnson-jb7xe He was in Mexico's secret Antarctic territory?
,,,,.........,.
Well, at least I can come here after SpaceX stood down from launch today! Thanks Scott for the great content!!
N Scale Train Boy same
Thanks for letting me know lol. I was thinking abt watching that. Guess I wont.
Wow. I remember when the majority of satellites passing overhead would appear to "flash" because of their spin.
Seems so oldskool now, but congratulations to Israel!
I'm from Israel, and I've wondered how we get our satellites into orbit. Thanks for the info, very interesting video.
BTW, if anyone is wondering, shavit means comet.
Thank you for your mandatory service.
Same lmao
Israel has no history only a criminal record liberty to Palestine death to the idf
@@Physhi Sadly, due to a disability, you have nothing to thank me for.
Love the Merkava Mk IV.
Still can't get over how weird that solar deploy is at 8:40
Glad I'm not the only one, haha
@Adi Adiani i doubt it
I like it. Each "fold" in the panel only needs to actuate from a 60 degree angle to zero, instead of something folded up on top of itself actuating 180 degrees as it deploys
I like it.
Adi Adiani You’re most likely an Islamic troll. Go somewhere else where there aren’t any educated people
Didn't know that South Africa had a mini space program in the past. You learn something everyday. Thanks Scott, great video.
Werner our space program had the RSA 3, which became the Shavit, there was also a RSA 5 concept which would have become our Mercury attempt.
South Africa developed nukes (supposedly with Israeli help) and then dismantled the nuclear program when they realized the regime change was inevitable. The ballistic missile was for the nukes.
@@PrinceAlhorian Would be great if that program could be restarted again.
@@zeevtarantov I knew that SA had nukes, six of them with a seventh one that was planned. Would've been interesting if that program continued, with the goal of having a space program.
@@wernerolivier1134 Sadly, not gonna happen... We now look to our boy Elon.
'you're launching in the wrong direction"
Israel: "shove it"
What??? You want us to launch with the earth circling east so in case of problem it will fall in Arabian soil?
@@odedshashua2763
no, he wants you to have a sense of humor.
9:02 as someone who was born in Israel, let me just say "makes just enough sense to exist" pretty much sums up Israel as a country, too.
Greetings from your NYC fan club Scott-Thank you for your extraordinary service to astronomy and space nerds the world over!
Great video, Scott. I had a lot of experience with the Shavit back in the late 1980s and early 1990s, none of it good. I worked for TRW Ballistic Missiles Division, and tried to get TRW into the space launch business using ICBM technology. Our then Vice President of the Space & Technology Division, Dan Goldin, supported our efforts - but he had been trying to make deals with Israel to commercialize the Shavit. He kept insisting that we use it rather than our own designs. I began referring to it as the "Jason", since, like the slasher killer from the "Friday the 13th" film franchise, we just couldn't kill it. A cabal of us at TRW wanted to use the Thiokol Castor 120 as the basis of a family of modular launch vehicles, all with significantly more capability than Shavit. While reviewing a classified Israeli design document on the Shavit late one night, I ran across some language that pointed to applications that were rather different from space launch. That was the end of TRW's flirtation with the launcher. Dan switched his support to our version using the Castor 120, and we were on our way to building a very robust launch business, with me as Director of Engineering. But then Dan got the nomination to become Administrator of NASA, and with his support no longer available, we were shut down one week later. Lockheed picked up our designs, and flew two of them (one to the Moon) successfully. But it never panned out commercially.
Israel has quite the interesting capacity on its own, impressive stuff
Nice to be best friends with USA ;)
Not bad for a country that came in to existence after WW2.
@@1blackice1 This is not US technology, cause ITAR ;)
It’s a shame their country can’t be united
thanks love from israel
I've always loved the simplicity of solid rocket motors. it's suppressing they aren't used more for at least the first stage, and maybe even the second, of the rocket. the design means they can have several on standby ready to go and only needing to fill the liquid top stages. they can also get away from the complex rocket motors, failure prone turbo pumps, and other hardware for the first stage which is what seems to be the most risky point of the launch with the most motor failures.
I think solid fuel rocket motors are often overlooked and underrated despite their lower efficiency over the liquid counterparts
They're certainly not overlooked when comes to ICBM design.
I am an Israeli. Thanks. Mr Manley. I like this video. Thank you very much. :-)
That's great. Back in 1973 when they decided they didn't get the intelligence fast enough they simply decided to start a Space Program from scratch. And they managed to do this in spite of all the hindrances. KUDOS!
And made a deal with South Africa for Uranium in exchange for the missile tech....
@@stanburton6224 Yep. They probably conducted a nuclear test together in 1979.
@@stanburton6224 it's a pity israel was doing deals with a deplorable regime like south africa, but when no one else is offering anything, you take what you can get.
even in later years US would refuse to share tech with israel, israel would say 'fine, i'll get it the hard way- R&D it on their own'. eventually US discovered it's a waste of time since israel will have the tech it wants eventually anyway
@@arieldahl hook or crook
@@arieldahl South Africa was known for its fine artillery pieces, though. Fine.
Scott brother thank you very very much for talking about my small country and I'm sorry for the comments,love you and your videos from Israel.
Unless I am mistaken; they write retrograde as well.
since its one of the most ancient languages, id say you are writing backwards :P
@@FiryaFYI technically, both Hebrew and Greek (from which Latin and English got their direction) descended from Phoenician which was written both ways... So it is a simple happenstance that Indo-european and Semitic languages picked each a different writing direction 🙃
@Lovecraft weren't Hebrew and later Arabic derived from Aramaic which had split off early Phoenician? Ofc, early Greek split off from a later version of Phoenician and then Cyrillic and Latin split off from it.
(we are talking about writing systems, ofc the languages themselves could have existed almost completely verbally before a writing system was developed somewhere else and adapted for it.)
@@ronenshtein7083 Hebrew and Phoenician came from the same root language
@@ronenshtein7083 Aramaic was spoken around 0 AD, Hebrew before that, Phonecian before that. Hebrew is an Afro-Asiatic language and has no common roots with the Proto-European Greek other than through loan words.
May you please do a small history on South African ICBMs and the Sub orbital rocket? id really love to see
Savit 0.1 model?
they had nukes too right ?
Great video, keep up the great work. Warm regards from Port Elizabeth, South Africa
As always extremely knowledgeable and never leaves a stone unturned! Keep it up Scott
Wow that was super interesting! Thanks so much for posting. really enjoyed it
Of course they launch east to west. They launch in Hebrew.
Thanks for putting this video up now, was just about to put my phone away after I learned the launch was scrubbed, then this came up :-)
Air launch also works well for them because of the solid fuel. Liquid fuel changes the design requirements when it's on it's side, but solid fuel can work upside down, sideways, and in zero g.
Scott, FYI the "ch" in Palmachim is properly pronounced with a guttural h sound. It's very similar to the Scottish pronunciation of "ch" in loch, for example.
It is funny how the amount of Hebrew corrections is huge compared to Russian.
like a Spanish J
Glenfiddich.
@Lovecraft It exists. It's like the ch in loch, as mentioned in the comment.
Israeli road signs have weird translations to English of the original Hebrew, with weird norms that are sometimes misleading, like "ch" instead of "h'", that sometimes causes tourists or people abroad pronouncing names in a wrong way.
As usual very good topic. Thanks for your good work. Mister Side from Montréal!
Love watching your videos Scott. And as always I do fly safe...lol!
I thought that Jericho was a Stark Industries product.
@TelAvivIL also the reason why the show Jericho is situated in Jericho and called Jericho. I miss Jericho. We should probably send nuts to the studio again.
Is it better to be feared or to be respected?

Great informative video as usual!
For your consideration: the Jericho
@Lovecraft I was quoting from the movie "Iron Man", but sure
@Lovecraft oh man you have no idea...
"I prefer the missile you only have to fire once."
"Excuse me, Mr Stark. How many missiles have ever been fired twice?"
Elon: "I'd have to check. Probably a couple dozen, so far...?"
I'm more worried about the Armageddon.
@Lovecraft The Samson option is probably aimed at Germany because they are most likely the descendants from the tribe of Dan and they would get worried that one day they will pull the temple down on their heads when they regain their strength.
God bless you for unapologetically using the metric system in your videos
Challenge get laythe in an SSTO only using retrograde orbits.
Also who wants to see a “Things Kerbal Space Program doesn’t teach Staging and Decouplers.” Because I do.
Great episode! Thanks
So they just Shavit into space??
Cmon someone had to say it
Indeed
They can take their rocket and Shavit...
Get your coat and see yourself out.
@@RCAvhstape fine, Shavit your way. If that's what you think is best
Someone just said 'Ofek it, just shavit up there!'

Woohoo! Another Scott Manley video!
I have been waiting for Scott to do a video on retro launches.

Some translations in case anyone is interested:
Shavit - שביט : Comet
Ofek/Ofeq - אופק : Horizon
Palmachim - פלמחים : Not a real word, just a name of a military base, a kibbutz, and a beach
IAI - התעשיה האווירית לישראל : Israel Aerospace Industries
Jericho - יריחו : Name of that city from the bible next to Jerusalem
Do tell me if I missed any terms
Scott the Shavit is actually a design started in South Africa. The RSA 3 missile was developed in my country as a nuclear delivery device, the rocket was taken over by the IAI when Krygkor (now Denel Aerospace) sold it in the middle 80's.
You got a source on that? I would be interested to know a bit more. According to Wikipedia the RSA 3 was a licensed copy if I am reading it correctly.
@@MeneerPietSkiet There was an old archival site, I will have to try and find it. I spoke to the engineer who worked on these rockets. Long story short, they were developed as a joint program by Israel and South Africa, Israel flew the prototypes as ballistic missiles South Africa started redesigning them for orbital velocities. There was enough difference to see the RSA as a different machine. With the cancellation of the program and the manned RSA 5, Denel sold the improvements to Israel and the modern Shavit is born. Basically a co-op development.
This is also the story with the Israeli Nesher fighter and the South African Cheetah. The resemblance between the two are striking, the were born from the same research project. The Nesher is more suited to dessert warfare and the Cheetah was built as a joint Interceptor and Air Superiority system. Not the best fighter plane ever, but at least we had some teeth in the 80's and 90's.
@@PrinceAlhorian Yeah, that agrees with what I've read too. There was extensive collaboration and joint development between South Africa and Israel during that time, including a possible nuclear test (Vela incident)
Israel is playing the game we played with the Soviets in circa 1960 in Cold War.
Every orbital launch is a statement of, “play it cool because we can hit you if we want to.”
Legit, when your launch platform is the same one as your ICBM, it's a solid message for sure.
@@MiishaKorvian, particularly if Gagarin's Step, when not launching manned missions, was also being used as a pad for the baseline R-7 ICBM with nuclear warhead.
@Lassi Kinnunen lol "conquered"
Iranian facilities are spontaneously explodes out of nowhere lol
Lots of clean low mileage 747s on the lot!! Cheers!!
Amazing smart nation.
Good luck and cheers from France Israel 👋
Damn I'm so close to Tel aviv, if I knew there was a launch last weekend, I would've tried to witness it since I've never seen one before...
They don't announce it in advance.
@@zeevtarantov I know, I just want to see one so badly :)
@@flodgey With an arm that long you could just reach out and touch it 🤣
Tel aviv statistically gayest city on planet earth lmao, GROSS
Man, the tsava do not anounce their launches. I was in Ashdod in 2016 when they launched Ofek 11. I heard a sound that reminded airplane engine. Then I look up and there is the trail of the launch going towards the Mediterranean.
I wanted to see a launch up close...
Another difference between the first two stages other than the longer vacuum optimised nozzle is the use of nozzle gimbaling for thrust vectoring on the second stage, vs jet vanes and aerodynamic fins on the 1st stage.
The ground facilities to build the missiles in South Africa are still here - we are trying to commercialise the place now and have some startups based there and we are trying to build a satellite but its cool seeing the 30 years old rocket facilities in South Africa.
Can probably organize you a tour if you are here.
Very Nice
I feel like a deep space update would be fantastic right now with the whirlwind of things that have been happening in space over the past weeks.
@Mr. Scott Manley. at 8:16 you talk about launching via a airplane. I think Stratolaunch Systems is looking for customers. Maybe someone you know can put them in contact with each other. Also, thank you for the quality videos you produce.
I hope Israel can expand their space program I felt bad when they lost their first astronaut on Columbia.
we actually cant.
We have a deal in place with america that they provide us with support but in exchange most ballistics advancements must be approved with them.
so our space program is very limited.
Thanks.
A private non profit organization almost landed a spacecraft on the moon (it crashed) in April 2019. Scott also made a video on it, as well as all space youtubers.
When you mentioned air launching it my first thought wasn't a 747 is was now the Stratolaunch would have a potential customer in that.
Right when spacex scrubs their launch
It could be air launched Minuteman style - out if a cargo plane, on a parachute, engine pointing down. It would take care of the wasted mass needed for the wings to pitch up and it wouldn't need the carrier plane to enter a zoom climb.
That's fascinating! Thanks for this video on a little known launch vehicle.
It's handicapped by the retrograde orbit, but if the Shavit is just launching spy satellites they probably don't need a larger payload capacity anyway. There's probably a parallel history of fantastic feats of miniaturization somewhere inside the Israeli defense industry, as they fit more and more hardware into the same limited payload size.
Retrograde orbits are awesome !!
@Scott Manley, does the retrograde orbit not also add relative (surface) speed to the satellite? Meaning that in one orbital period, they traverse the earth a little more than once?
Much love from Israel
Really interesting video!
But I think it would have helped to have a comparison between the rockets, and the figures on screen. I was a bit lost at the end tbh.
No comment on the Shavit doing a massive shart at 7:10? ('Shart' is a technical term, so I am told...)
Hey scott just thought you’d like to hear this, but i got my wisdom teeth out today and afterward i said “I’m scott manley, fly safe!” so many times lol.
Shavit - good name
nice
Another reason for the retrograde launch is it would take the Intel it needed then download it to Israel without relying on relay stations.
Hi Scott. Thanks for mentioning the South African connection.
Just Shavit up there mate💪👆😁
Hey awesome video as always! Love it. I'm just here to supply the obligatory nit picking / pronunciation tip:
At 2:13 its is pronounced Palmah'im, with a sound similar to Mexican 'x', or Russian 'х'. Just FYI :)
כן, ניסיתי להסביר שזה h עם רעש של ליחה...מסובך להסביר את האות ח
isn't it like the mexican 'j'? like jalapeno?
Or more apposite, three Scottish 'loch'!
He's a Scot. You can hit closer to home with Scottish pronunciations!
C'con bro, he's a Scot! You can do better than Mexican and Russian. How's about Glenfiddich?
Great video again. Have you read "The Daleth Effect"?
Question for Scott or others. How do all solid motor rockets achieve the correct orbital parameters? Is there enough control over the exact fuel amounts added to each rocket that it hits the correct orbit? Do they adjust the timing of the later stage firings if needed? Do they have some way of stopping the burn a little early? Or do they just get it approximately in the correct location and carry enough RCS fuel to make corrections? Do atmospheric and weather conditions have enough effect that the amount of fuel required changes based on the exact temperature, pressure, etc. of the atmosphere in the flight path? (if so, how is that adjusted)
5:18 Happy, friendly satellite.
can u do a video explaining japanese rockets family?
Such a bummer that the launches are not announced ahead of time and perhaps only local ATC gets a few minutes of warning when the countdown is already proceeding well. By chance, I got to see a launch but did not know what was happening at the time due to the dissonance of watching at night from about 4km distance exactly perpendicular going out to sea and not seeing a trajectory.
If you have a ramjet first stage; air launch can be very beneficial in helping it get to "ramming speed".
A raptor powered shuttle-like vehicle launched by StratoLaunch could loft modest payload and a couple astronauts to orbit and then land on a runway. No launch delays due to weather and flexibility in where it can be operated from. Are you listening Space Force?
They should really revive XS-1 with raptors instead of the AR-22.
Ladies and gentlemen, for your consideration... The Jericho.
"...it makes just enough sense to exist."
More than could be said of some other rockets these days...
oRaNgE rOcKeT bAd
What are the ridges on the nose cone for?
cool
Sea launch Shavit might be another option. How proofed against salt corrosion is it at the moment?
Not to be confused with the Chevrolet Chevette, sometimes known as the "Shove-it".
I owned one of those rolling trash dumps. You are not wrong. EVERYTHING broke on that car. Finally gave up, when it pushed a cylinder head through the side of the engine.
It still strikes me odd that you say flying the ship. I have to think of rockets as the top fuel dragsters of airplanes. Where is the line between flying/driving and hanging on for the ride. Thanks, appreciate your work Scott.
Thank God for Scott Manley content when SpaceX has to do a weather-related scrub and trust me the launch team was mad they wanted to get this thing off the ground but due to weather constraints no joy No Light in the candle today.
Shavit means "comet" in Hebrew, and Ofeq means "horizon".
cool!
Shalooom, I'm Scott Manley !
I'm slightly surprised they haven't tried launching from a barge instead, though that obviously comes with its own challenges.
Israel needs its own capability because they know that at any point their supposed friends will turn against them when an arab looks at them with a frown, playing with a valve to an oil well.
It's happened to Israel time and time again, and taught them they need to be as independent as possible in all respects.
Cool it with the persecution complex pal. You need independent capability because being dependent is never a good thing.
Most people wouldn't have a problem with Israeli state if it weren't for the way they treat Palestine and repeatedly expand through illegal settlements and annexation.
@Kathy Sharp that exact attitude is the reason why peace in the middle East is so hard to attain. When someone just goes "bomb the Arabs, who cares that they are just men, women and children trying to live and get along in life, screw them all".
If you took your comment and replaced the word "Arab" with "Jew", you'd be excoriated (and rightly so) for anti-semitism.
@@ValleysOfRain Yet it was the Arab League who vowed they would wipe Israel off the face of the Earth and repeatedly attempted to do so. Only relatively recently did some of the neighboring countries back off the total annihilation attitude slightly.
@@MarvinCZ In any other situation, I would say that the Israeli government and the Arab governments deserve each other, however there's a lot of innocent people on all sides who are bearing the real cost of this saber rattling and war mongering.
Syria is ruled by a dictator, Iraq is still recovering from being the West's punching bag for the first decade of the 21st century. Egypt has been under multiple authoritarian regimes backed by military coups, Jordan is an absolute monarchy - your average Arab doesn't get a say, same in Saudi Arabia, and then you have Iran, who are not an Arab nation, but originally they were quite a friendly nation to the West. Then the Shah tried to nationalise Iran's oil industry and was met by a Anglo-American backed coup by the radical, hyper conservative insurgents who then formed a government that is a Junta in all but name. One who regularly performs violent crackdowns when massive protests against the government pop up.
But sure, the normal Arabs and Iranians deserve it, I'm sure.
They have been in development for a while, first observed by 3 wise men.
Your accent when pronuncing Palmachim is great. Shavit is a comet in Hebrew btw.
4:32 - In the simulation the map beneath the satellite has names on it :)))
What's that burning stuff falling down at 7:11?
I am Israeli, thanks for this information. :D
