bits and bytes....

 

I watched the US  "State of the Union" last night, but on PBS and missed this. The .gov feed had shown this image while talking of innovation....

This pick was mentioned on reddit as stage movement to LC40...but had no mention of time or a time stamp...if a photo buff could zoom to cleaned grid fins, it would tell us time placement....

Thought this was neat...Kamag haulers, each wheel independent, steerable and independent suspension.....same company but different model...

Ok, so there is news popping up all over Twitter that SpaceX received an AF contract to help them develop the Raptor engine on the path to RD180 replacement. This surprises me to be honest, because:

 

1. Like the BE-4 this will be a Methalox engine.

2. As such it cannot drop in on Atlas V as a mere replacement with some minimal tooling.

3. Does this imply that SpaceX would eventually be interested in selling their engines to a third party that builds a rocket around them?

 

What is going on here?

When SpaceX's Jeff Thornburg testified before Congress in June 2015 he said of Raptor,

Raptor could have significant applications for national security space launch, all while significantly advancing U.S. industrial capability and technology with respect to liquid rocket engines. With a highly scalable engine cycle, Raptor's "light and tight" design is built for operational functionality, cost efficiency and long life in high production volume, which makes it ideal for NSS needs.

The engine utilizes a closed cycle with the objective of achieving the highest performance possible for a methane rocket engine while also delivering extended reusability through new SpaceX technologies and more benign turbine environments.

Key engine components and large structures have been additively manufactured, and Raptor will be the first large liquid engine in the world constructed largely with printed parts.

Raptor directly contributes to the rapid advancement of oxygen-rich and full-flow staged combustion and additive manufacturing technologies for the United Statesenhancing U.S. industrial capability.

Further, the engine enhances state-of-the-art, high-performing EELV-class propulsive capabilities for future flight engine systems to support commercial and NSS applications in accordance with Fiscal Year 2015 National Defense Authorization Act (FY15 NDAA), Section 1604.

The flexibility of the Raptor design enables the technology to be applied to existing EELV-certified launch vehicles.

I would predict that being a full flow staged combustion engine, the first operation engine of this type, it'll have serious thrust/weight advantages over BE-4 which uses a more conventional cycle.

In reference to this...

 

With Eutelsat Win, SpaceX has Business with All 5 Top Satellite Fleet Owners

 

Quote

BRUSSELS, Belgium – Satellite fleet operator Eutelsat has selected SpaceX to launch the Eutelsat Quantum or another Eutelsat telecommunications satellite, a contract that gives SpaceX business with all of the world’s top five commercial fleet owners, industry officials said.

 

Paris-based Eutelsat declined to comment on whether it had sealed an order with SpaceX, as did Hawthorne, California-based SpaceX. But industry officials said that Eutelsat booked a firm order in the latter half of 2015.

 

SpaceX received two satellite-launch orders from Canada’s Telesat in 2015. The Eutelsat contract means SpaceX has in its backlog — for the Falcon 9 Full Thrust or the future Falcon Heavy version — orders from SES of Luxembourg; Intelsat of Luxembourg and McLean, Virginia; Eutelsat; Telesat and Inmarsat of London.

 

While satellite owners usually insist that their satellites be compatible with all the major commercial rockets — the Ariane 5, Falcon 9 and Russia’s Proton — they have preferences that are often based on their comfort with launch providers. Conducting a successful launch is the best way to build comfort and make the next launch contract that much easier to win.

 

The bigger its fleet, the more often an operator must launch just to maintain its current business. SES and Intelsat, for example, together operate around 100 satellites, meaning they must book a combined six satellites per year in replacement capacity alone. Growth capacity would add to that number.

 

Despite the many one-satellite national satellite owners being created mainly in emerging-market nations, a launch service provider, like the neighborhood restaurant, cannot survive without repeat business.

 

Eutelsat launched its 115 West B satellite aboard a SpaceX Falcon 9 v1.1 rocket in March 2015. But the launch had been booked by Satmex of Mexico before Eutelsat’s purchase of Satmex. Eutelsat’s 117 West B is scheduled for a SpaceX launch in 2016, a contract that also came with the Satmex acquisition.

 

Eutelsat officials said they were impressed with the accuracy of the Falcon 9, which enabled their all-electric 115 West B to reach its operating position several weeks ahead of schedule, enabling an early start to service and revenue.

 

More than any of its rivals, Eutelsat has wrapped itself in the European flag. Almost all its satellites are from European manufacturers, and it has been one of Arianespace’s best customers.

 

SpaceX’s lower-cost commercial offering has been the bête noire of Europe’s launch sector, and of some European politicians, for several years, making any choice of the California company by a European operator a source of controversy.

 

In 2015, when Airbus Defence and Space tentatively selected SpaceX to launch the Airbus-owned EDRS-C data-relay satellite — whose mission received financial support from the European Space Agency and European Commission – French politicians lined up to protest the deal.

 

Airbus ultimately switched to Arianespace after what industry officials said was supplemental European government financing so that the Ariane 5 launch cost Airbus not much more than a SpaceX launch.

 

One European industry official said the same thing may happen again, especially if Eutelsat decides that it is the Eutelsat Quantum flexible-payload satellite that will launch on SpaceX. Quantum is a European Space Agency-financed effort, with the British government the principal backer.

 

Eutelsat said Jan. 12 that it had made no decision on what rocket will launch Quantum.

 

Eutelsat is free to select its own launcher, even in a public-private partnership such as Eutelsat Quantum — just as was Airbus for EDRS-C. But the political fallout may be more than the company would want to bear, especially without a British government signal that it was comfortable with the choice.

 

The kind of pressure that even private-sector operators feel when the go outside Europe for procurement was in clear evidence here Jan. 12-13 during the 8th Conference on European Space Policy, held at the European Commission.

 

Several European government officials and parliament members called for stricter rules binding all European governments to select European launchers.

 

But Europe’s private sector and some of its governments continue to go outside Europe for satellites and launches.

 

The German government used Russian rockets for its first-generation radar reconnaissance system, and has purchased two launches from SpaceX for the three-satellite SARah second-generation constellation. The program’s prime contractor, OHB SE of Bremen, Germany, has said only by using an old Airbus launch option with SpaceX was it able to meet the contract specifications and stay within the German government’s SARah budget.

Hispasat of Spain is the most recent European operator to select SpaceX, with an order placed in 2015. A second Hispasat order went to International Launch Services of Reston, Virginia, for Russia’s Proton rocket.

 

Hispasat Chief Technical Officer Antonio Abad told the conference that Hispasat had selected Ariane for eight of its 11 satellites so far, with the remaining three going to SpaceX, Proton and the U.S. Atlas 5.

 

“Diversification is important for us,” Abad said. “We are very good friends of [Arianespace], but we need to maintain alternative suppliers. We need to have competition to make sure the launchers are competitive, and to maintain schedule assurance. We need several launcher providers.”

 

Abad said that a company like Hispasat must  “maintain neutrality among our suppliers. We want to be able to select the satellite we want, and to launch it on the launcher we want. Don’t forget that.”

Nothing id being said due to the above. Gets bad when one has to hide a launch till last minute from a subsidized launcher or it gets overturned.

Heh, weird to see a rocket on that spot without the strongback holding it... then again, the strongback can't hold it like this anyway since it grabs Falcon 9 by the 2nd stage :p

 

Also... why does that Ben Brockert guy keep calling it Falcon 9.2 :s That is just as silly as all those masses of people that keep spelling the company name wrong (the short version at least)... 'Spacex', 'Space x', 'Space-x', 'Space-X'... Geez guys... how hard can it be... it's 'SpaceX'! No more, no less. Ah well... /rant off

The strongback is there, its just laying horizontal on the other side.

 

They brought it in, attached its launch mount (which has the hold down clamps), unlocked the tower and laid it flat. Then they craned in the launcher and attached it to the mount. No need for fancy stuff if you have a practical design and a good crew of crane jockeys on staff.

 

Gotta love those SpaceX pad rats.

After its been completed would be preferable.

Yea sorry it wasn't clear at all there! Do we know when the test will be completed, and how long it will take them to announce that it was a success? I am presuming there wont be a live video of it.

The static fire is only part of this test, signs are they are also fine tuning the new LC-40A propellant supercooling system using the landed stage. The supercooling system was a tad twitchy during the ORBCOMM 2 wet dress rehearsal & static fire and they'd want to nail it down before the SES-8 commsat launch campaign in 3 weeks. Once they do a static fire long enough to get good data (all 9 engines reach 100%) they'll issue a tweet, then report on the data analysis shortly after. A day or two is typical.

 

This process with Falcon Heavy may take time to smooth out as well since it'll have 3 cores and 27 engines. Due to happen this spring.

Rumour has it that the stage would have sat a long time waiting for 39A to be ready and therefore decided to use 40 instead. As Doc said, now kills two birds with one stone (metaphorical in case PETA on the prowl).
