The same thing is being mentioned in several places elsewhere, but to put some numbers on it:

Orbital velocity is in the vicinity of 7500 to 8000 m/s. At that speed your KE is 1/2.m.v^2 which is about 32e6 Joules/kg.

Orbits are, conveniently, at about 320 km, so your PE is m.g.h, or about about 3.2e6 Joules/kg.

In other words, the energy to get to orbit is ten times the energy to get to the altitude of orbit, and this exercise only got to 1/3 of that. So the energy involved was about 1/30 of that required to put something in orbit.

It's still a fantastic achievement, and an important - nay, critical - step on the way to properly reusable rockets, but it does lend some perspective to it.

TLDR:

Blue Origin did a soft landing from above the Karman line. SpaceX is trying to do that from orbit. The former involves speeds 10x less and energies 100x less than the latter.

Still a hard thing to do no matter how you look at it, but the two goals are not trivial to compare.

I see so many people complaining about the comparison but no explained it more clearly, thanks! Quick question though, isn't SpaceX trying to land just the first stage?
Re:New Shepard: Bezos claims success on second spaceship flight by Florin_Andrei on Tuesday November 24, 2015 @02:35PM (#10623025)
I believe they want to eventually land and recover all pieces.

Well, kind of. The F9-1 would be on it's way to orbit, but not there. It's a first stage after all. It would certainly have much higher energy, and is huge in comparison.

Comparing one- and two- stage rockets is a bit of a handicap, since no one (yet) is talking about landing a single-stage-to-orbit rocket.

The best numbers I can find say that the Falcon 9 stage separation is at around 80km and 2km/sec (2.8 MJ/kg of total energy), and the Falcon 9 has so far failed to land under power.

Yes, there are lots of subtleties about staging and so forth, but lots of people are talking about that elsewhere. I just thought I'd put some number to the simplest possible case so people can see the magnitudes we're talking about.

That's neat.

But what I see on video is Bezos landing a rocket and Musk blowing up a rocket.

I understand the technical differences, but in terms of media, this is a pure win.

What I see is Musk supplying the ISS, and Bezos doing a PR stunt.

Let's try comparing those on more than just media, shall we ?

Re:New Shepard: Bezos claims success on second spaceship flight by fixermark on Tuesday November 24, 2015 @03:06PM (#10623266)
Perhaps, perhaps not.

Financially speaking, between the two goals, there's enough money concentrated in private individuals' hands that you might be able to find six people willing to shell out for space tourism.

Government funding supplies the ISS. A laudable goals, but there's a grim realpolitik view that suggests it's not as guaranteed sustainable of a market as space tourism.

On the other hand, SpaceX's goals also allow for deployment of orbital payloads... Now that's lucrative.

There are plenty of videos of Musk successfully landing a rocket? Just never actually landing one from orbit.
Re:New Shepard: Bezos claims success on second spaceship flight by jacquesm on Tuesday November 24, 2015 @10:33AM (#10621275)
No-one has managed a landing from orbit. Yet.

It would be a breakthrough of Gaussian proportions!

>> That's neat.

You make a very good point about public perception. But your opening line seems sarcastic and aggressive. I think that's why your comment is light grey.

Not that I have any skin in the game - I think Musk and Bezos are both insufferable billionaire jerks, scamming taxpayers and working the lower class to death - but Grasshopper went to 250m, while Blue Origin went to 100km.
Re:New Shepard: Bezos claims success on second spaceship flight by baq on Tuesday November 24, 2015 @05:13PM (#10623945)
it's not that much of a difference, going almost straight up and falling mostly straight down is a matter of burning longer. it is an achievement, it's just not useful for much (for the price) and overengineered at that. if it actually went to orbit and didn't come back, it'd be a bigger thing.

* Excluding your "media win" part of the comment.

Parallel parking a Prius vs. parking a dragster is different. But as you said, you understand the technical differences.
