In 1962, John Glenn went into orbit on an Atlas rocket, and thus began a family of rockets that lasted for 60 years!

Atlas: from a vehicle for warheads to a vehicle for eggheads.
I've had the chance to work on the latest rocket in this family. It's a true beast and you can practically feel the history when you watch it loft a rover and helicopter toward Mars. Can't understate the importance of the Centaur either. It's been around nearly as long as the Atlas and is rooted in the same design as the original ICBM. In a way, the original Atlas from the 1960s is still flying today. It's just a little smaller and carrying hydrogen instead of kerosene.
Pretty awesome, I can assume. Taking a robust design and having your team to make it a more modern outfit.
i won't lie..
i'm honestly looking forward to one day having a rocket called 'rocky mcrocket-face' or a satelite called 'satty mcsatelite-face'
and the scientists behind it will groan and then smile as they get to come up with an insanely long *yet accurate* name that can be spelled as such.
I want that.
Just refer to these using the names of all the famous Vulcans through history. :)
Dwayne The Rocket Johnson
Soon as Hank said they let the internet name it, of course my first thought was Rocky McRocketface. And my second thought was that the internet has warped all of our minds.
RIP SciShow Space, we'll miss you.
Thank you for the great video
i like how no one ever mentions that alan sheppard was the first american in space. for years i always thought it was glenn because no one cares enough to talk about sheppard lol
Lovin' the Boaty McBoatface reference, lol.
Most people think John Glenn was the first person in space, but it was actually Alan B Shepard. I would love to see a video about him. Thanks
No that was Yuri Gargarin
When he said "crewed" I heard "crude," at first. Ah, the English language.
I'm not sure that anyone in 1945 thought that an ICBM was possible, except perhaps Wernher von Braun and some of his team. It took over a decade of development from the Aggregat-4 (V-2) to achieve the kind if range needed for intercontinental reach.
In the year or two leading up to John Glenn's orbital flight, there was much rivalry between the army and the air force concerning rocket development. The first two manned Mercury missions (those of Alan Shepard and Gus Grissom) were launched on Redstone rockets, because, at the time, these were the ones least likely to explode on the launch pad.
Once the Atlas was thoroughly proven, and modified as you describe, it was used on the Mercury programme. The first two Mercury-Atlas launches were unmanned, although the second did carry a chimpanzee named Enos.
I'm not sure the reason behind the stage-and-a-half design was the difficulty of igniting a second stage in flight. They did, after all, have hypergolic propellants available. I think the main reason is that it was the most expedient compromise between the simplicity of a single-stage design and the thrust-to-weight benefits of a multi-stage design.
Small nit: At 1 minute 30 seconds, an illustration of Atlas 2nd and 3rd generation vehicles are shown, when the video speaks of the 1954 development of the original. Atlas 3 and later vehicles share only the name and none of the tech of the original SM-65 missile, which the illustration doesn't include. Great video otherwise and appreciate the shout-out for a legendary launch vehicle.
thank you
Cool.
@OP Says a lot about us who took our best, cleanest, brightest soldiers, strapped them to the largest towers of explosives ever constructed, and blew them clear off the planet.
I hope they'll make a Sea King pin of the month!
One of these days they'll make an RMRF...
Oh boy, new Scott Manley video.
WD-40 was invented in San Diego in 1953 as a rust-prevention solvent for Atlas missile outer skins. A chemist at the Rocket Chemical Company created a compound that would prevent rust and corrosion on the Atlas.
The Air Force built an Atlas silo in a corner of my great grandparents’ farm in Nebraska.
1:45 and hence the near miss that occurred when an ICBM lit off in Arkansas in 1980 (known as the Damascus accident) when technicians accidentally pierced said shell while performing maintenance when the wrong size socket fell off of the wrench and pierced the skin whilst ricocheting down 😅
They should have named the new rocket "Phallus"
Ah, it's the Chevy small block of rockets! Gotcha
Does Anybody know how the Atlas-Agena got named? I ask this as a Agena.
Agena was the name of an upper stage. A lot of older American rockets were named [Missile]-[Upper Stage]: Atlas-Agena, Thor-Agena, Thor-Able, Titan-Transtage, Atlas-Centaur, Thor-Delta, just to name a few. Agena is the traditional Latin name for Beta Centauri, and Lockheed (who built the Agena upper stage) likes naming their stuff after stars.
the usa should have done this again to get back into orbit
How fitting
A rocket that was the first to lift us toward the sky named after a figure that holds the stars
If people want a bit more detail Scott Manley covered the evolution of the Atlas a few years ago ua-cam.com/video/TeGmIeu0xvI/v-deo.html
no way you did this on New Horizons launch month
The Atlas V may be getting retired (now that the Falcon 9 and Falcon Heavy basically succeeded it while costing far far less per launch) but we will always appreciate the two decades of service it provided us, including launching New Horizons. Godspeed, Atlas V.
The Little Engine That Could ain't got nothin' on Atlas.
Oh come on guys... can't you make some crappy pins for a change?
I'm going broke keeping up with collecting the ones I really like and having them sent out to me month after month. 😑
It’s too bad they can’t restart Saturn V rockets. Apparently they don’t know how they were built. Ah government
I believe it's not that it's unknown how they were made, but more the techniques used at the time to create certain parts has become, for all intents and purposes, impossible to replicate and far more efficient to use more modern parts thus requiring a redesign. It's like, much cheaper to build a Model T with modern parts and a slight redesign than trying to replicate absolutely everything from scratch. Doesn't mean how it was made is forgotten.
Technology for heavy lift rockets has changed. Now, the least expensive, most reliable way to provide a lot of first stage thrust is solid fuel boosters. That was not true in the 1960’s. The main trend countering solid fuel boosters is SpaceX style reusability. You need the restart and throttling capability of liquid fuel rockets for that, but reusability was also not a thing in the 1960’s.
@@relwalretepYeah, when they tried to rebuild the J-2, they ended up making a nearly-completely new design.
@@innosam123 there's a reason lots of retro computer fans are building fully compatible PDP11 machines out of Raspberry Pi boxes, heh
Why have rockets running down the side. The vehicles center massive
You should change the name of this channel and SciShow to SciShow Compilations and SciShow Space Compilations. That's all we get these days. Old videos. Hank Green et al resting on their laurels! Been watching your channels in 2013! Pfft!
I'm still sad they didn't have the courage to name the boat Boaty McBoatface. Cowards.
Metric!
Date is year, then month and day.
All of this is international standard everyone understand, not some 'Murican „speciality“.
First?
I named the Pokemon in my nuzelock after you, you have a good name
@@lordnickstorme nice im honored
rocky mcrocketface isn't a fun name, it is reddit tier cringe.
When I poop out ice cubes, I have an icy BM.
