CONTRACT RELEASE: C12-019

NASA MODIFIES LAUNCH SERVICE CONTRACT TO ADD FALCON 9 ROCKET

CAPE CANAVERAL, Fla. -- NASA has announced a modification of its NASA
Launch Services (NLS) II contract with Space Exploration Technologies
(SpaceX) of Hawthorne, Calif., to add an additional configuration of
the Falcon 9 rocket to its fleet. The SpaceX Falcon 9 v1.1 launch
service will be available to the agency's Launch Services Program to
use for future missions in accordance with the on-ramp provision of
NLS II.

The NLS II on-ramp provision provides an annual opportunity for new
launch service providers to compete for future missions and allows
existing launch service providers to introduce launch vehicles not
currently on their NLS II contracts.The NLS II contracts are multiple
award, indefinite delivery/indefinite quantity contracts with
ordering periods through June 2020.

The NLS II contracts support the goals and objectives of the agency's
Science Mission Directorate, Human Exploration and Operations Mission
Directorate, and the Office of the Chief Technologist. Under the
contract, NASA also can provide launch services to other government
agencies, such as the National Oceanic and Atmospheric
Administration.

The Launch Services Program Office at NASA's Kennedy Space Center in
Florida is responsible for program management.

"to add an additional configuration of the Falcon 9 rocket to its fleet"

What's all that about, Block 2?

Jim?

It says "Falcon 9 v1.1", whatever that means. M1D?

Whoa, now that the name's out of the bag...

Page 20 of this Iridium PDF has this:

"FALCON 9 v1.1 (B2) SpaceX, USA"

And this image... Is it me or are the engines no longer in a 3x3 arrangement, but rather an octagon with a center engine? Also check out what might be strapon attachment points (and crossfeed points?)

Based on the fairing size, the length of the booster seems to check out with the reported 69m figure. Note also that the 2nd stage appears to have more than doubled the propellant load of the current Falcon.

Sure looks like an octagon to me, but then I'm on my iPhone. Time to boot up the graphics workstation....

 The Iridium reference is a couple of months old. Could it just be the fairing version?

B2 = Block-2, I presume.

Well, off to Chris's new thread! Let the speculation surge!  :P

The Iridium reference says, quote

I can only imagine B2 means Block 2.

So is this how one raises the price without actually announcing a price increase. It's the new v1.1 model, which of course costs more.

The interstage appears to be shorter, unless Mvac nozzle got shorter too, that means the whole vehicle is now wider. Which would explain the new engine arrangement.

Don't jump all over me for this.....but just read this:

http://forum.nasaspaceflight.com/index.php?topic=28868.0

Now read this new version.  Question are they related?

Doesn't NASA require testing for the changes?

It looks from the outside like the changes are too fast without testing.  Put it another way....has the new system been tested at Stenis, its good enough for Orbital etc.

I have my concerns on this.

We all still have concerns about Block 1, let alone Block 2.

Doesn't look wider to me, based on assuming the 5m fairing is as large as before. Maybe they cut the nozzle extension down somewhat?

Another thing is there are no engine fairings any more. Either the M1Ds can really be packed like sardines compared to M1C, even with the new arrangement or... I don't know.

This is just an on-ramp, not a mission buy.  NASA won't even let a new rocket bid on a mission until it has a successful flight, and at least 3 successes before it can launch a low-risk science mission.  HQ did not require such provisions for COTS or Station Resupply.
If I like something on NSF, it's probably because I know it to be accurate.  Every once in a while, it's just something I agree with.  Facts generally receive the former.

Closer shot of the cluster for clarity - sure does look like an octagon.

#1- We need to move/merge this to the other thread.

#2-It's just bigger, plain and simple. It's taller, wider, and so is the fairing. The only thing that's stayed the same size are the Merlins, even if they are D's now.

Several posts unrelated to Falcon 9 v1.1 also got merged (i.e. the ones about differential throttling, etc).

I was under the impression that the Falcon 9 was the maximum diameter that could be transported over roadways, and that was the driving requirement (transport costs from Hawthorne to McGregor, back again, to the Cape, etc.)

If it is wider, what changed? Is the above not true, or are they finding a way to widen it and still transport it over road, or are they transporting via a different method?

Not to say it would but, would this new configuration be able to lift heavier manned payloads to LEO such as Dreamchaser or Orion?
