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.
'Few in November'? lol

Timothy. Calm down. Take a deep breath. Spelling isn't that hard. It reflects really poorly on this site when the editors can't spell. This happened on the article just before this too.
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.
It just gets better... "The company has taken another step toward its goal of taking the well off and adventurous on suborbital jaunts for fun and profit."
Huh? I keep trying to interpret that.
I think all companies should "take the well off" and "adventurous on suborbital jaunts'
That's not so bad. You need to read it as The company has taken another step toward its goal of taking the well off and adventurous on suborbital jaunts for fun and profit.
"the well off" and "adventurous" refer to people. "suborbital jaunts" is what they'd be taking part in.
Less is more.
"Well off" should have been spelled "well-off".
Should at least have used the correct "well-off". The whole blurb is a disaster of written "English".
The "first" here is that New Shepard made it to the altitude arbitrarily defined as "space". The first launch and landing of a VTOL rocket that had previously flown was back in September of 1993 with DC-X's second flight (first was 8/18/93). Sure, it only went up a few hundred feet ... then stopped dead, hovered, translated sideways another couple of hundred feet, then landed. (I was present for that one. Frickin' awesome!) It flew yet again less than three weeks later.
On June 7 and 8 of 1996, it flew twice within 26 hours. That second flight reached an altitude of 10,300 feet (its record). Nowhere near space, but the DC-X program was more about the control software and reusability than going for altitude (it was a one-third scale prototype of the proposed Delta Clipper). And they were doing it with what is now over twenty year old technology. (Actually older, the thrusters were modified RL-10s from the 60s, much of the flight control avionics was off-the-shelf units that McDonnell-Douglas used in its jet aircraft.)
So, kudos to Blue Origin for reaching the edge of space with a previously-used rocket (something nobody else has done with the arguable exception of Shuttle, which was really never the same twice). But let's put the "first" emphasis where it belongs. (And it is significant -- it doesn't really matter how many times you can re-use a rocket if it won't get you to space in the first place.)

Hopefully, this leads to a bit of a space race.
However, to be fair, SpaceX is a LONG LONG ways ahead of everybody. They already have an orbital craft. They are able to land their first stage. They will likely re-use it in production sometime next year.
FH will launch in April.
Dragon v2 for human launches, will be end of year.
Raptor is supposed to be finished and fully tested around early 2017.
And that is on-top of MCT being developed.
OTOH, ULA, Airbus, O-ATK, Russia, etc will feel the heat shortly.
I prefer the "u" in honour as it seems to be missing these days.

Honestly, you got it almost completely wrong - you don't need to scale the engine at all (you rather lose some payload to orbit) - and the fuel you need to lift the rocket (full, heavy) is magnitudes higher than you need to land it back again - SpaceX uses 9 engines on the Falcon 9, and has "engine-out" capability, where one (or even two, if the right ones fail) engine can get inoperative and the rocket will compensate with a slightly longer burn to still achieve orbit. For doing so, you have to take the fuel for that "slightly longer burn" with you anyway - even if you don't need it. This very fuel will then be used for a landing burn if everything goes smoothly - the rocket either turns around (now nearly empty, and only ~20 tons) and burns toward the LZ, or follows a more or less parabolic arch to a waiting ocean barge (for high-performance launches) to land, where only the last 100m/s or so have to be killed via propulsive landing, the rest is bled of in the atmosphere (terminal velocity etc.) - we are talking about a ton or two of fuel here, which is nearly nothing compared to the rest of the rocket.
The same goes for propulsive Landing on Dragon btw. - you have a Launch Abort System onboard which needs fuel, that you have to carry anyway - if the launch goes smoothly, you take that fuel back with you - and use it for propulsive landing (with parachute backup if something happens - you need that one for the launch escape scenario anyway).
Hope that clarifies it a bit...
It's not twice the fuel. It takes most of the fuel to get to speed. At that point the booster is SIGNIFICANTLY lighter, so it takes (again with that word) SIGNIFICANTLY LESS fuel to slow down, and then to land.

That's because BO had the luxury of being able to hover as desired, pick the landing spot and descend. The first landing had it skating all over the place.
The Falcon 9's single merlin engine produces too much thrust to hover, so it has to burn to hit 0m/s at 0ft. This is due to it needing the engines to lift an actual payload into orbit, as opposed to simply going up and down.
BO also had the luxury of choosing their launch time and location without commercial constraints. The F9 launch had a 30 second window, so to delay because of the fog (which Musk alluded to causing the ice buildup) wasn't an option.
Blue origin landed a suborbital rocket twice!
Slashdot thinks Flew and Few are one and the same.

Fix the fucking glaring typo, you barrel of twats. And while you're at it, fix the mobile bug where I get told I have 5 moderator points which expire 5 days ago. And why am I never logged in automatically like on other sites? To look at it, you'd think this was someone's first site circa 1995.
