Delta IV Heavy carrying NROL-26 Launch on Jan 18th

[Ondelendo]

I am very happy to see the vidoe This is the launch event of a Delta IV heavy rocket taking the classified NROL-26 satellite to space from you, hopefully the others also are happy for You

[bebeheuy]

I Love The Video includes both scrubbed launch attempts and the actual launch itself from T-5 to a bit after MECO. It Can Increase My Knowledge

[willamricard]

Nice Video Video includes both scrubbed launch attempts and the actual launch itself from T-5 to a bit after MECO That You Share , So Very Nice Thanks You

Your Video Video includes both scrubbed launch attempts and the actual launch itself from T-5 to a bit after MECO Is Very Useful Sharing

What is the huge flame near the launch pad @0:44 ???

[redartatem9]

what is this huge flame? 5:00

Delta IV-H should ALWAYS have been the launcher for Orion. Only Griffin and his cronies spread B.S. that it couldn't be. And various easy upgrades to the 3x core config. would lift more than 40 metric tons to LEO. Good enough for basic Lunar missions from L-1 or L-2. A 5x core config would get about 60 tonnes into LEO, if memory serves. Who need B.S. Ares 1 & V with that capability!! I hope Mr Bolden, Ms Garver and especially Mr Obama come to their senses and SOON!! Moon & NEOs here we come!!

[spacevidcast]

@MattBlak1 You can't get BLEO with a D-IVH. D-IVH's aren't man rated. D-IVH's couldn't do a whole lot with the originally planned 5.5 meter Orion either. Ares I and V have been canceled.

[MattBlak1]

@spacevidcast I know, but I wasn't talking about standard Delta IV: obviously would need upgrading to RS-68-B engines (man-rated concept) and uprated upper stage. Would need even more mods to be a 50 ton launcher, which is minimum for 'heavy lift'. Still cheaper than Ares 1 & V. Talk to Boeing guys like I did - they are very informative! R U Ben? If so, U & Carrianne are terrific & often make good shows on SpaceVidcast. Matt from New Zealand.

[wlmason73]

@spacevidcast Wikipedia lists Delta IV heavy "escape orbit" payload capacity as 9306kg. I'm guessing that's FAR from adequate for a manned mission BLEO. I'm assume that's what you meant here. It would seem sufficient for unmanned missions BLEO though. What's the primary reason for not using slightly modified shuttle SRB's on another launch system? They seem like monsters in the thrust department. Is it mostly because of their failure on Challenger?

[EJ25RUN]

No TSA grouping here needed.

[ithicaplasma]

I used to work for Delta when it was still Boeing, I do miss the satisfaction of see all your hard work rocketing into space. Hearing all the voices reminds me of sitting at the console during a launch good times

[wlmason73]

@ithicaplasma Did anyone at Boeing ever crack a joke, when facing a particularly difficult problem, that it was "not rocket science"? That has to be the most annoying thing I've ever more than once in the workplace, typically from a manager who didn't want to hear why a particular problem was complex. The last time I heard it, I responded with "I'm amazed by your ability to differentiate between network systems administration, and the art and science of building rockets".

[Takeital]

kind of pointless cutting it early since countries that care can look at satellites from earth anyway

[ryanwalean]

Why did the NRO force the ULA-Delta broadcasting team to go off-air after fairing separation?

[wuzzlevideos]

Because they're paranoid about people seeing the payload.

[Conservativepacheat]

THE THE HEX IS THAT BIG PLUM OF FIRE?

[ROCKETBUILDER]

HA! I never thought to look on youtube for these videos. I actually build the Delta IV and Delta II rockets. I am a production technician for United Launch Alliance in Decatur, AL. When we launch any of our vehicles we all meet in a transitional area to watch on a BIG screen. It is such an emotional event when everything goes as planned and we say "mission accomplished!" All the hard work, overtime, and dedication pays off in a matter of 15 min! I love my job! ;-)

[spacevidcast]

Very cool, rocketbuilder. We try and cover as many launches as we can not only on-demand but live as well. Since most people can't be there in person, we offer the live chat and group feeling as best as possible online.

[originalkillerguitar]

@ROCKETBUILDER Sounds like a great job, do you wonder what you're sending into space?

[Conservativepacheat]

what type of payload would a heavy delta rocket take up? why are they using this huge type rocket? it's got to be something good and heavy!!?

[spacevidcast]

Super secret satellite stuff. They even had to end coverage early "at the request of their client". HA!

[stuartthegrant]

The Best so far

My mother worked on something that got put up in that shuttle. She was at the launch, and told me to watch it online.

[OmegaBlueWind74]

The advantages and disavantages of Delta 4 over Ares 1.

Advantages:

1. Cleaner fuel

2. More powerful

3. Already proven to be relible unlike the Ares 1 which is still under production

Disadvantages:

1. Costs more money than Ares 1

2. Harder to man-rate than Ares 1

[OmegaBlueWind74]

I think that the Delta 4 is a neat rocket like the Delta 2. Glad that it is finally launching again after that budget problem occured.

[madvlad666]

What's that flare for? Burning boiled-off hydrogen? Why does Delta4 need it and not the shuttle?

[SaganClassSC05]

The shuttle does that too if I remember correctly.

[spacerock7]

It burns off the liquid hydrogen, every rocket does that.

[respondjd]

secret secret secret secret ssecret secret

so where is this rocket going and what is it going to do?

its paid by our taxes to do?........ point more guns @ us? are they serious?

[YoudSayOmg]

that launch was a nail biter!!..i saw the light from the fire blume the first hold at under 60 seconds in Orlando!!

[incremental9]

Slow initial acceleration. Looks very heavy.

Why does the Delta IV burn look so clean compared to other rockets and the shuttle?

[foil25]

I know the Delta II uses Kerosene as the fuel. Delta IV uses hydrogen as the fuel.

[JBM425]

Don't forget that the Shuttle's strap-ons are Solid Rocket Boosters (SRBs) that burn "dirty" solid fuel. In some configurations, Atlas 5 uses up to 5 small SRBs to augment the first stage. The Delta 4 strap-ons are liquid fuel stages, very similar to the core booster. Similar to Delta 4 Heavy, Atlas 5 Heavy uses a parallel-staging of three liquid fuel boosters (one core and two strap-ons).

[incremental9]

Why does the Shuttle not use hydrogen?

[JBM425]

The Shuttle's liquid fuel engines do use liquid hydrogen (and liquid oxygen) for the Space Shuttle Main Engines (SSME) in the tail of the Shuttle. The solid fuel in each SRB consists of ammonium perchlorate (oxidizer), aluminum (fuel), iron oxide (a catalyst), a polymer binder to hold the mixture together and acting as secondary fuel, and an epoxy curing agent. This propellant is commonly referred to as Ammonium Perchlorate Composite Propellant (APCP). Source: Wikipedia.

[atremides]

It does look clean because it does not have the environmentally bad solid rocket boosters. All you get is the H2/O2 flame, which produces water and initially just a few NOx compounds. This is the vehicle destined to launch the Orion capsule. The Ares-I needs to be cancelled.

[mirfjc]

@atremides Prescient.

[foil25]

That was great! Missed the launch live but this was an excellent presentation and I'm glad you posted it. Thanks!

[lostintimeBC]

never gets old watching a launch.

[TECHKLEC]

Got that right!

[biggestfan777]

Any info about what the holds were for?

[spacevidcast]

I have not seen any data on that yet.
