The company's founder and chief engineer, Elon Musk, has said SpaceX will attempt to fly Starship to an altitude of 15km to demonstrate the performance of three Raptor engines over the course of several minutes. The company's previous flights to about 150 meters, in August and September, used a single Raptor engine.
This higher flight profile will take Starship above nearly 90 percent of Earth's atmosphere

The author is a dumbass.

90% of earth's atmosphere is 90km, not 15. Space is at 100 km altitude.

The atmosphere isn't uniformly dense up to a sharp cutoff at 100km. Most of it is near sea level.

This.  Air pressure at 15km is about 10% of that at sea level.

15km is just a bit under 50,000' ... about 15% of sea level density

Well space is recognized internationally at 100 km.

If you want to get technical, you could say that the atmosphere ends at around 10 000 km altitude with the exosphere.

If the author wanted to be right, he should have said that the flight will go above nearly 90% of earth's troposphere.

Doubling down on your farking ignorant statement.  For shame.

The arbitrary line for where space begins is not even relevant here.  Indeed Earth's atmosphere extends for many thousands of miles. The ISS is in the atmosphere and because of atmospheric drag must occasionally fire thrusters to raise its orbit.

When someone says x is above 90% of the atmosphere, what they mean is above 90% of the air molecules of the atmosphere. This meaning is standard and indeed the only meaning that even makes a lick of sense.

Okay, for you pedantic types, the author meant that the vehicle will go above 90% of the atmosphere's mass.

Imagine a hamburger.  The two buns are each 1 inch tall with a radius of 3 inches and a weight of 2 ounces.  The burger is also 1 inch tall with a radius of 3 inches, but it has a weight of 6 ounces.

If you eat only the meat and not bread, you would have eaten 1/3 of the volume, but 60% of the mass.  Conversely, if you eat only the bread, you would have eaten 2/3 of the volume, but only 40% of the mass.

In this case, the vehicle will have passed through a large portion (approximately 90%) of the mass of the atmosphere (along its flight path), but only a small percentage of the volume of the atmosphere.

He is not being pedantic, he is just dead wrong.

Why do you think airliners fly around 10km high?

Personally, I am looking forward to the big explosion.

The chances of getting this right first time IMO are slim.

I have no doubt it will get done, and become as reliable as the Falcon 9 is. Now it is no longer news for them to land one of those and that will be the case for Starship.

But the first few times?

Big Bada Boom.

The first time they nail it, like with the Falcon, I will be jumping up and down shouting.

My prediction is that it explodes on the launch pad.
