The plane is in the atmosphere. The rocket is not.

I think that depends on what you call "the atmosphere." If we go by the Karman Line, that definition of the boundary between Earth's atmosphere and outer space is 100 km.

According to this link, the first stage booster of the Falcon 9 separates at an altitude of about 80 km.

Falcon 9 Launch Timeline

Of course The Karman Line -- while having some logic and rationale behind it -- is also a little arbitrary. The exact altitude that defines the boundary of space is ambiguous, since atmosphere just gradually thins as you go up, and there is no distinct edge to the atmosphere. However, if they want to have a distinctly defined altitude for the edge of the atmoshpere, they have to set it somewhere. Hence the Karman Line of 100 km.


EDIT TO CORRECT:
I incorrectly stated "50 km" for booster separation. It should be 80 km (50 miles). I made the correction above. Sorry for any confusion.

Jets fly in what I call the atmosphere. The separation occurred nowhere near the jet.

Ah. And that's a valid point of view if you want to define atmosphere in that way -- i.e., generally as the troposphere, the place where we and other animals live our day-to-day lives.

But yes, the jet was no more than 7 miles up and the rocket separation was 50 miles up.

More importantly, the rocket was almost certainly not even above the same part of the Earth as the jet. The rocket might have been a few hundred miles laterally away from the jet. That is to say, the rocket was likely not "over" the jet.

i feel like im in a horror movie but instead of zombies its just stupid people.

we're outnumbered

for the person who doesnt know who the falcon rocket is made by.....HI! welcome to earth. spaceX is the answer your looking for.....it even said so in the video.

The rocket is still in the atmosphere otherwise those boosters would not be returning to Earth.

Incorrect.

Try again. Those booster rockets are still in the Earth's atmosphere at separation for the express purpose of returning to Earth. I'll give you time to use Google so you can educate yourself on how far the Earth's atmosphere extends from the surface.

Of course I looked at the image. Very, very technical. I like how it omits any reference to the various layers of the Earth's atmosphere. But the stars are a nice touch.

Like I've said before. Use Google and find out "how far the atmosphere extends from Earth"

Those booster rockets are still inside the Earth's atmosphere. So you still remain incorrect.

Okey dokey. Try breathing up there. Or flying a jet.

No, no, no.

You are wrong and your comment to the poster was INCORRECT. But keep trying to back peddle your way out of being wrong.

You're implying an atmosphere is relevant to oxygen and the ability to create lift? I skydive at levels where I need oxygen and I'm still in the atmosphere. Show me where the definition of an atmosphere has any relevance to creating lift.

a reply to: 1point92AU

and your being pedantic.

a reply to: 1point92AU

You're implying an atmosphere is relevant to oxygen and the ability to create lift?

Well, it is. It also is relevant for the operation of jet engines. But mostly I'm implying that the rocket was nowhere near the airplane. Rockets don't breath air and they don't use aerodynamic lift.

But if you want to be really pedantic forget the Karman line. The atmosphere extends way beyond that and it seems that the criterion is arbitrary.

It seemed clear from these cases that the physics of space still held sway well below the Karman line. When McDowell used a mathematical model to find the exact point at which various satellites finally broke loose of their orbits and made a fiery return to the atmosphere, he found that this could occur anywhere between 41 to 55 miles (66 and 88 km). Usually though, when a craft dipped below the 50-mile (80 km) mark, there was no hope of escape.

But, if you want to depend upon an arbitrary criterion, Ok. You are correct.

There is nothing arbitrary about the accepted definitions and scientific observations of the Earth's atmosphere.

You can try to back peddle all you want and I could care less about being "correct".

Interesting. I guess when it comes to the calibration and sophistication of on-board equipment, real time computers processing landing calculations there's really no need for precision. Maybe you and Phage can let Elon know next time he sends up a rocket he should just just estimate at what altitude the boosters need to jettison. I mean since being precise and accurate is irrelevant according to you and Phage.

Actually, now that I think of it there was a job posting on the SpaceX website recently stating "Rocket Scientists Needed - Precision Not Important". LOL

That has more to do with the parameters of the planned orbit than the character of the atmosphere. Because at that altitude, there isn't much.

Speaking of Elon:

Highest reentry heating to date. Burning metal sparks from base heat shield visible in landing video. Fourth relight scheduled for April.

Heat shield? Reentry? I wonder what the booster reentered.

You can wonder all you want. You're still wrong.

You clearly don't understand the definition of 'arbitrary' when dealing with the atmosphere. Which we all know you were wrong about. But please keep posting graphics of booster rockets with stars in the back ground. That one was funny.

The fading must be accelerating.

I think I do. Do you think the atmosphere just ends somewhere?

The Kármán line thus is an arbitrary definition based on the following considerations:

en.wikipedia.org...

What did the booster reenter? Or is Elon also incorrect about his booster?

LMFAO!

I'm so sorry but i'm dying here, i shall steal this for future use, hope you don't mind : )
