There's nothing for ULA to worry about yet. SpaceX recovered one first stage. Until they can do this on a routine basis and also reuse each one at least once they won't have significantly brought the cost down.

Oh yeah
-
Getting closer...
I got very lucky landing it upright on the first attempt. Timing & throttling the final burn is very tricky even with MJ's suicide burn countdown information. The result is more often something like this...

- A few people simulated the barge-landing in KSP but I have yet to see anyone turn their rocket around to come back to KSC
After reading this I decided to give it a try myself. Success on first attempt.
-
Tried my hand at flying a first stage booster back to KSC. First I made sure a reasonable dummy payload would make it to orbit with an early MECO of the booster. Then I launched again and tried to fly the booster back to KSC. First a bootback burn at Ap, then a re-entry burn to limit the speed through the thicker part of the atmosphere then a nail biting suicide landing burn.
I used MJ to give me altitude and time to suicide burn data. I'm used to Mun landings and this was scary. With a mostly empty booster and a Mainsail the burn comes at the last second with a high vertical velocity. But I pulled it off at the first attempt. Of course it didn't land AT KSC, but NEAR it.

Wow looks like it nailed it!
-
Just found this vid on YouTube... It's taken from a distance but shows the landing and includes sonic boom (not heard until after the touchdown)
-
yeah probably two exposures otherwise the nearby lights would be much brighter.
However it was made its an amazing picture!
-
Yeah Left is ascent and right is the return for sure. Remember the launch path goes east over the Atlantic and it returns from the west and that the launch pad is tot he north of the landing pad. The photo appears top be taken to the north west of the launch pad.
-
Hopefully Space X will release some HD video from the pad in the near future, and just imagine what a daylight landing will be like!

That was SO AMAZING. I'm in Jacksonville, FL, and I got to see it from my yard. I saw it go up, watched the stream on my Surface tablet, and then watched it come back down through the clouds.
Wow that is very cool!

11 Satellites in orbit and one booster back at the launch site! amazing!

Hitting the target has never really been the problem. It's hitting the target softly enough to stay upright and not explode.
Exactly, they've demonstrated that they can put the booster down at a specific location so there should not be much concern about it crashing into the VAB or something. Lets hope that the vehicle does not RUD on arrival this time!

Gadzooks. It sounds like somebody didn't expect the Spanish Inquisition...
Nobody expects the Spanish Inquisition! [DRAMATIC CHORD]

SpaceX's lack of transparency is very frustrating. If this was a NASA launch there would already have been a briefing and news conference explaining what is (or is not) happening.
SpaceX please think of the Space Nerds!

....or do they use two unrelated pronunciations for the same word with the same origin depending on whether they're talking about a body of water or a political region?
Yes.

Arkansas, USA. I'll leave it up to our friends in Kansas and Alabama to decide whether that's technically a Southern or Midwestern state. xD
(As a funny side-note for our foreign friends who are unaware of this fact: Despite apparently differing only in the additional syllable at the beginning, "Arkansas" is pronounced nothing like "Kansas". The longer state's name is pronounced as a dactyl, with the second 'a' an undefined sound closer to a soft 'e' and the final syllable pronounced like a tool for cutting. The shorter, at least when spoken in the dialect of a native from my state, is a trochee that enunciates the first syllable like it's written, but sounds like the second should be spelled "zus". I would blame this inconsistency on an attempt to Romanize words borrowed from the natives' language, but that still doesn't explain identical spelling for very different-sounding words.)
In Kansas the Arkansas River is pronounced "R-Kansas" and for some reason the Kansas River is called the "Kaw".

Ummm.... well.... I sent up the Mun Lab Expedition 2 crew via SSTO to the LKO station where they boarded the nuclear powered crew transfer vehicle Relayer II. After a stop off at the fuel depot in HKO (Relayer II has done two round trips to the Mun and was running low) they headed for Munar orbit. On arrival while preparing to rendezvous with the orbital Mun Lab I noticed that the Mun Lab was no longer there!
This is a bit of a problem.

Headline: Crashed Plane Flying Too Close To Ground According To Investigators.
Other than design flaws its usually when I'm doing low level flying, buzzing KSC or moving the camera around for a glamour shot...
That or trying to land a VTOL. I can do it safely most of the time, but certainly not ALL the time!
-
Oh! Oh! I so want to use this!

From orbit? Only way to be sure.
One of the best movie quotes ever
-
Just for fun I decided to turn my SSTO Rocket Pane into a shuttle like thing with the addition of a big booster.
Launched from a standing start
This got it into orbit with ~1500 m/s to spare..
So I decided to orbit the Mun with it
On the way home
Of course the re-entry speed was much higher than usual. I picked a high initial Pe to limit the heating, but it still lost the nose cone on the first pass, de-orbited on the next pass through the atmosphere and landed safely

Past launch vehicle: Saturn V /Apollo
Current Launch vehicle: Delta IV Heavy.. its the most Kerballistic real life launcher. One rocket not enough? strap three together (MOAR BOOSTERS) and if that wasn't enough it tends to catch fire during launch!
-
Mun Lab Expedition 1 returned home on Relayer II after a try out of the new reusable Mun Lander and supervising the addition of a Cupola to the orbital lab.
While they were at the Mun Lab Kerbalkind had upgraded Kerbin.
Luckily the LKO station was still there along with a ride the rest of the way home.
