For comparison, SR-71 Blackbird can only fly up to 85,000 feet. So he jumped 1.5 times higher than that. However, the edge of space (Karman Line) is defined at 100km, or 330,000 feet. So he jumped about 0.4 of the way of that karman line.
Felix is one sharp cookie. I've never seen an interview of him or heard him talk before. He's very articulate, respectful, thoughtful, clever, funny and intelligent...
I still remember watching that jump and being amazed at the achievement. Congratulations on being one of the few to have that amazing view of the world
I’ll never forget this moment in time. I was so frightened when I realized that Felix was out of control and lost consciousness. It was his training that allowed him to recover and regain control to successfully deploy his chute. It’s hard to imagine what it must have felt like to be in near vacuum with virtually zero resistance but still moving faster than the speed of sound. Unreal!!!
I don't know where I was when this jump occurred. I don't know how I missed this. I had never heard of this jump until watching this episode a couple of days ago. When I saw the title "Jump from the Stratosphere" silly me was thinking the Las Vegas Stratosphere not THE Stratosphere. I am so geeked. Since watching this on Friday, I have watched so many videos on this jump. This is crazy and amazing at the same time. Thank you Dr. Neil; you have taught me so much in the time I've been watching!!!
Terrific interview Neil! I can't believe that it's been ten years already! Kudos to Felix on an incredible accomplishment! He is the epitome of what goes up must come down! 👍👍👏👏
One of the most interesting Parts was when the world's greatest astrophysicist said, "I didn't know that" about the meaning of a base jump! Proving, anybody can learn something new everyday! We learn something new from you too everyday Neil, thanks!
The 'world's greatest astrophysicist'? Too bad he's so misinformed to claim that from the skydiver's jump height of 39 km (24 miles) the earth's curvature still wouldn't be visible to the human eye. In interviews, Baumgartner has stated that the earth's curvature WAS observable.
Such an interesting interview! I remember watching his jump at a friend's house, we took a break from our poker game to do so. We were all so stressed out, and relieved when he landed! Also, this is the most visually pleasing Star Talk episode, with the black/cream backgrounds and clothes of Neil and Felix. Details.
I can't even begin to fathom , not only the view when he stepped out to the ledge, but the INCREDIBLE amount of courage it took to understand how high he was and still take that step... Because I don't think I could have done it.
Felix got Nick Pinantaneda's jumps confused. He descended safely with his gondola on the attempt where he couldn't disconnect his O2 hose. It was on his NEXT attempt that he lost suit pressure and eventually died. He had a BAD habit of momentarily opening his helmet visor to release some pressure because his helmet ring kept coming up. There's a theory that he did so around 50,000 ft on his last jump and could not get the visor closed and sealed fast enough.
@@MoahGentle The sad thing is if he'd had a wrench to get the O2 hose undone o the previous attempt he would've lived. en.wikipedia.org/wiki/Nick_Piantanida
It's crazy when I think about it but when he first jumped from the balloon and reached the speed of sound there was not much air resistance, so there wasn't any air whooshing sound as he fell thru it. Pretty much silent at first for awhile. That's awesome.
I was at airshow and high fived and thanked to Felix, very cool and easy guy and big show man. Big respect and good luck to him. Thx Neil for having interview with him.
Between how you describe the atmosphere slowing you and the SciShow episode asking the question if we are fish this pretty much sums it up as we are fish, but we live in a very thinly dispersal of H20 molecules mixed with a remainder of Sol's cosmic gases that passed us on their way out to the bigger gaseous planets that formed in the outer orbital belts of our solar system. So it appears.
Some tidbits @05:50 Yes, the wing suits are steerable but not necessarily you can glide up in updrafts because the total aspect ratio, square of the span b^2 / A area of the wing is very small for human wing suit compare to paragliding parachute. The large sea birds can glide in place in updraft but tiny bids cannot, same principle here. The base jump and sky diving parachute both has low aspect ratio, because the purpose is not fly long distance but land immediately after finish sky diving at same or near place where is jump. @07:55 Mach 1.0 is Sonic speed, Mach >1.0 is supersonic speed. Bullet speed (depends on cartridge but most bullet) travel at Mach 2.0 to 2.25, so his velocity was less than speed of bullet and close to sonic speed.
Thank you sooooo much for this great insight...superb interview of supersonic man. 😊loved sky diving always .never knew about this " Base jumping" WoW!!!! So much knowledge ❤️❤️❤️❤️ Thoroughly enjoyed and learned a lot. Thank you so much.
Hey Neil! I was at your talk last night at the Sacramento speakers series. I thoroughly enjoyed it. I tried buying your new book but they were sold out. Something that was new knowledge to me is that you are a fountain pen fan. What's your pen/nib/ink? I'm a LAMY 2000/F/Namiki blue. Thanks for a great evening.
03:19 We don't see planes at that altitude because no plane has ever flown at 130,000 feet. I think he was thinking 30,000 but since they were talking about 130,000 he slipped. Only the X-15, which didn't take off under it's own power and thus excludes it, has ever flown above 124,000 feet.
You get a quick glimpse of a completely flat horizon during the video. Shout out to the editor who left a little Easter egg in the video letting us know it's a fish eye lense and they've easily lied to us for 500 years.
@fromnorway643 usually when there's extreme curve even below commercial airline altitude or when there's amature footage from an air balloon of a completely flat horizon wayyyy higher above the pictures were showed of a curved earth.
@@milesalton4003 here are a few examples of the Earth's spherical shape without a fisheye effect 🔍 Turksat Deployment 🔍 Japan Lunar Orbiter 🔍 Himawari Weather Satellites And btw the globe model was introduced by Greek scholars during the 3rd century BC

But happened to the balloon and capsule? How much higher did that go? Where did it end up? How long did it take to get back to the ground, or did it go into orbit?
Eventually, they returned to Earth. The balloon would have Eventually popped, if they didn't set it up to release its own helium. It wasn't high enough, or fast enough to go into orbit.
@2:02 of course someone was higher than him: Alan Eustace broke Felix's record 2 years later in 2014 at 135 000 feet. Self funded also in a balloon and space suit, but almost nobody talks about it because he didn't had any big shot sponsors.
On the subject of risk takers, I have an example. I have a Horse who is very calm and trusting, but when she wants to venture from her sleep space out to where she likes to graze, she will walk to the doorway and just stand there looking out. I can't lead her, nor can I push her through the doorway. As much as she indicates wanting to go out, she refuses. I must walk out first, and she'll wait to see if there is anything there to eat me. Only if I'm safe, and haven't been eaten, will she follow.
Reminds me of the only thing I’ve known Neil to get wrong. He said in a talk that at the height Felix got to you wouldn’t see the curvature of the earth.
That's out of context. He's was talking about looking down and seeing the ground bulge up to you like it looks in fish eye lens. He wasn't talking about whether you could see the horizon curving from a tangent.
@@EBDavis111 It's been a long time since I watched the video so I'll take your word for it. I'm not going back to dig it up or anything as I like Neil and I'm not trying to discredit him or anything. Just an observation really. To have hours upon hours of talks and I've only ever heard 1 thing I disagree on is quite an achievement.
What an amazing sight it must of been.... Its sad to think basically all of us will never be able to fully appreciate Earths glory from within a situation like he did..
He did speak about it...he said there was really no air, Soo there nothing he could do till he got to 90,000 ft where he started to able to control he's free fall...have a blessed day TBEV 🙏🏻
@@willmolina7395 true, I heard that part...but they didn't specifically mention it, or if he blacked out...what effect it had on him...that type of thing...I just thought it would have been interesting to hear more in depth. Cheers.
They aren't going to focus on the most important part when he started spinning almost out of control and everyone thought it was out of control and he leveled himself out it was amazing
I never asked is he gonna die. I just was tooo excited. I don't even know him but i cried with excitement when he landed. Just watching this makes me cry my lashes off😂❤
Hi Algo, Did he go super-sonic without ever breaking the sound barrier? Since the air was so thin, the sound didn't put up much of a "barrier". Is that correct? Thanks, Rithm.
Breaking the sound barrier _is_ the very definition of going supersonic (above Mach 1), but yes, that's much less of a barrier when the air is ~100 times thinner than close to sea level.
There is a saying in sales. It is regarding being well known or the best at something. "It is better to be first, than to be the best. " in other words if your the first to do/make something, it is better for you EVEN if your not the best. If you can be both then you invincible!
his was the highest free fall jump but not the first from space by far. On 1 November 1962, Yevgeni Andreyev and Pyotr Dolgov ascended from Volsk, near Saratov. Andreyev jumped from the capsule at 83,523 feet (25.458 km) and free fell 80,380 feet (24.50 km) before successfully deploying his parachute. Dolgov remained in the capsule and ascended to 93,970 feet (28.64 km). Astronauts have been using that as training exercises as far as I know to test out the spacesuits capabilities. I'd like to know what the speed of sound actually is in the thin air of the stratosphere? also what was his terminal velocity from the long fall. does terminal velocity change as the atmosphere gets denser? I remember it being something like 32 Ft/Sec^2
Joseph Kittinger jumped from 31.3 km on August 16, 1960. The speed of sound in air depends mostly on temperature, not density or pressure. It is at its lowest (~295 m/sec) near the tropopause and in the lower part of the stratosphere, but rises with the rising temperature higher in the stratosphere and reaches about 330 m/sec near the stratopause where the temperature approaches 0°C before dropping again in the mesosphere. Yes, terminal velocity does change with air density. That’s why Felix was able to break the sound barrier at that high altitude, but his speed had slowed to about 200 km/h in the lower and denser atmosphere before he triggered his parachute. 32 ft/sec² or 9.81 m/sec² is not the terminal velocity, but the _acceleration_ in freefall on Earth if there is no resistance. Terminal velocity is the velocity or speed in which the gravity pulling down equals the air resistance pushing up, and the falling object stops accelerating. It depends on air density, but also on the shape, size and density of the falling object.
You forgot to mention, however, that Dolgov's helmet visor hit something as he exited and his suit depressurized....he was dead when he reached the ground.
Felix was in free fall for ~4 minutes and reached maximum speed after ~1 minute. If we assume the worst case ( 900 mph to 0 mph within 3 minutes), it would result in an average deceleration of ~2.2 m/s² or 0.23 G. Seems like something not to worry about ;)
should have been pretty much just 1 G of interaction since the slowing was gradual, altho, when the parachute was deployed and when he went from terminal velocity to "full canopy" he most likely experienced 2-3 Gs for a couple of seconds.
G force decreases with altitude so as he got lower he had a little More g force and atmosphere which allowed him to measure and control his parachute pull at the correct height and g force.
Would you take this jump?
Absolutely..Why Not..🪂🤙
YES!
I would jump from the atmosphere of Mars.
Fastest Man, alive
Yes. Just enough time to come out as someone else on the other end 🙂
High five to Felix 10 years later. For a guy who has been so high, he is really well grounded.
Good sense of humour
lol also hi five for doing the quick conversion on the fly around 9:45 or so Neil asked one I don’t think he was prepared for lol.
Lol you can't gain enough altitude to high five Felix
Hahahahahaha awesome
For international fans of Startalk: 130,000 feet is 39,600 meters or 39.6 km up. That's incredible.
now that is high
I had to do the conversion to KMS to get an idea how high it was.
@Cognitive MGTOW I think you kinda missed the point of my comment.
For comparison, SR-71 Blackbird can only fly up to 85,000 feet. So he jumped 1.5 times higher than that.

@@MoahGentle He NEVER lost consciousness - Baumgartner said that he 'felt like' he was going to pass out. In actuality, he never did.

I remember watching it live and a few times after. Amazing. I'm going to watch it again. Epic interview!
I remember watching the whole thing live. Several very exciting hours that made history.
Felix hasn't aged a day since that jump. I still remember the look on his mother's face as he went up. Admirable feat and an amazing character.
I guess that as a professional sportman (so to speak) he lives a very healthy lifestyle.
Ten years isn't that far
Well he aged 10 years during the jump so he was ahead of time lol....j/k
This was a great discourse between a physicist and an adventurer.
Great, great interview!
I's love to hear more of the technical side of the whole mission. It would be great to have this guest back!.
Nice interview! It was interesting how Felix said he wasn’t a daredevil but the jump was carefully considered and executed.
fantastic interview! Felix seems like a awesome person, what an insane moment in human history and one that I will personally never forget
Great video Neil and Felix! Thanks for making it!

What a great interview. Loads of respect for both of you. Humans can do anything if they work together. Very inspirational. Thank you Neil.

He did pass out. But then he woke up.

Andreyev jumped from the capsule at 83,523 feet (25.458 km) and free fell 80,380 feet (24.50 km) before successfully deploying his parachute. Dolgov remained in the capsule and ascended to 93,970 feet (28.64 km). Astronauts have been using that as training exercises as far as I know to test out the spacesuits capabilities. I'd like to know what the speed of sound actually is in the thin air of the stratosphere? also what was his terminal velocity from the long fall. does terminal velocity change as the atmosphere gets denser? I remember it being something like 32 Ft/Sec^2
Joseph Kittinger jumped from 31.3 km on August 16, 1960.
The speed of sound in air depends mostly on temperature, not density or pressure.
It is at its lowest (~295 m/sec) near the tropopause and in the lower part of the stratosphere, but rises with the rising temperature higher in the stratosphere and reaches about 330 m/sec near the stratopause where the temperature approaches 0°C before dropping again in the mesosphere.
Yes, terminal velocity does change with air density. That’s why Felix was able to break the sound barrier at that high altitude, but his speed had slowed to about 200 km/h in the lower and denser atmosphere before he triggered his parachute.
32 ft/sec² or 9.81 m/sec² is not the terminal velocity, but the _acceleration_ in freefall on Earth if there is no resistance. Terminal velocity is the velocity or speed in which the gravity pulling down equals the air resistance pushing up, and the falling object stops accelerating. It depends on air density, but also on the shape, size and density of the falling object.
You forgot to mention, however, that Dolgov's helmet visor hit something as he exited and his suit depressurized....he was dead when he reached the ground.
Great talk
I like this guy more now, he’s pretty humble
Love this episode!
I am wondering about G Forces as he re-entered a thicker atmosphere. Dr. Neil, can you answer?
Felix was in free fall for ~4 minutes and reached maximum speed after ~1 minute.
If we assume the worst case ( 900 mph to 0 mph within 3 minutes), it would result in an average deceleration of ~2.2 m/s² or 0.23 G.
Seems like something not to worry about ;)
should have been pretty much just 1 G of interaction since the slowing was gradual, altho, when the parachute was deployed and when he went from terminal velocity to "full canopy" he most likely experienced 2-3 Gs for a couple of seconds.
G force decreases with altitude so as he got lower he had a little
More g force and atmosphere which allowed him to measure and control his parachute pull at the correct height and g force.

The Earth's gravity is only 1.2 % weaker at 39 km altitude, so that wasn't really a factor to worry about.
I can't believe it has been 10 years! Wow!
Find your stratosphere. Build a team. Make a plan. Jump, that others may follow.
