Blue Origin Launches and Lands the Same New Shepard That Few In November (blueorigin.com)

MarkWhittington writes: The commercial space race between Blue Origin and SpaceX got more interesting on Friday. In November, Blue Origin launched its New Shepard booster on a suborbital flight, and then successfully landed it afterward. On Friday, Blue Origin relaunched the same New Shepard spacecraft to a height of 101.7 kilometers, and then landed it a second time. Blue Origin has therefore accomplished a first by flying a vertical takeoff and landing rocket into space twice in a row. The company has taken another step toward its goal of taking the rich and adventurous on suborbital jaunts for fun and profit.

No comparison

How can anyone compare Blue Origin and SpaceX in the same paragraph while still mentioning that Blue Origin flights are sub-orbital? There's really little basis for comparison at that point between Blue Origin and SpaceX and more comparison between Blue Origin and Scaled Composites. Of course Scaled Composites *already* flew multiple sub-orbital flights with SpaceShipOne - who cares that it wasn't a vertical take-off and landing - it's *still* more comparable.

They're not, technically. And SpaceX has already done *lots* of rocket landing with the Grasshopper test vehicle.

The hard part is scaling the technology up enough to be useful - there's lots of non-linearities in the real world that confound such endeavors. Just a couple:

Getting up to speed while carrying a second stage requires a LOT more fuel, meaning the difference between launch weight and landing weight are MUCH greater. To the point where the Falcon uses only one of its nine engines when landing, throttles it down as far as it can go, and still is producing too much thrust to be able to hover. And being able to hover makes a *huge* difference in ease of landing - just stop a few feet above ground and then ease yourself down, rather than having to time things perfectly so that you hit zero vertical speed just as you touch down. Stop a foot too high and you can't get down short of cutting the engines and falling, stop a foot too low and you get serious impact damage.

Wind shear - thanks to the much taller profile, torques from ambient breezes are going to be much greater on the bigger rocket, increasing with roughly the square of height.

LOL.
They already comply with NASA and DOD standards and still their prices remain a fraction of ULA, Airbus, etc.
And as to extracting money from the feds, ULA is nearly 100% dependent on the feds, while less than 1/3 of SpaceX are from govs.
And when it comes to getting 'subsidies' from the feds, they take in a FRACTION of what ULA, Boeing, L-Mart, Airbus, BAE, etc take in. Hell, in all of these other companies, they require the feds to pay costs+, which is ALWAYS outrageous profits, while with SpaceX, the feds have paid only a fraction of the price. SpaceX continues to pour their profits into R&D.

Finally, if they are so far behind that they are only 50's tech, then what companies are ahead of them and how much lower costs are they?
