ЦитироватьUS Air Force leader eyes SpaceX launch certification by June
 WASHINGTON, March 10 Tue Mar 10, 2015 11:16pm EDT
 
 (Reuters) - The U.S. Air Force hopes to certify privately-held Space Exploration Technologies, or SpaceX, to launch some U.S. military and intelligence satellites into space using its Falcon 9 rocket by June, a top official told Reuters on Tuesday.
"I think we're still looking at ... June," Lieutenant General Ellen Pawlikowski, the top uniformed officer in charge of Air Force acquisition, told Reuters after a speech at the annual Women in Defense conference.
Pawlikowski, nominated by President Barack Obama to head Air Force Materiel Command, said she was disappointed the Air Force had not been able to certify SpaceX for the launches by December, as initially hoped, but said she was "encouraged that we're close."
The general said allowing SpaceX to enter a market dominated by United Launch Alliance, a joint venture of the two top Pentagon suppliers, Lockheed Martin Corp and Boeing Co , would let the Air Force leverage the commercial market and help reduce the cost of launching satellites into space.
Pawlikowski, who trimmed the cost of satellite programs by $3 billion during her tenure as the head of Air Force Space and Missiles Systems Center, welcomed a variety of initiatives under way across the Pentagon to benefit from investment by commercial firms like SpaceX.
She cited some lingering institutional resistance to change, but said the Air Force was working more closely with industry to understand how simple adjustments in requirements for weapons systems could lower costs and free up resources for other work.
She said one key step was empowering acquisition officials to look at innovative products and solutions instead of turning to the same suppliers and products that had always been used. (Reporting by Andrea Shalal; Editing by Jeremy Laurence)

Уже 87. Впрочем с основной ПН может и девяносто. Запуск на F9, но с особым блоком довыведения SHERPA и со спутником ДЗЗ из Ванденберга, а посему быстро не сойдут с орбиты.

Seattle-based Spaceflight said the new funding round, which was confirmed in a filing with the U.S. Securities and Exchange Commission (SEC), brought its total funding to $27.5 million.
Spaceflight has several business lines related to small satellites but it has become well-known recently as the company that has arranged for 87 small spacecraft to be launched aboard a SpaceX Falcon 9 rocket later this year and then deployed into low Earth orbit from Spaceflight's Sherpa carrier.
The launch, to occur from Vandenberg Air Force Base, California, will set a record for the number of spacecraft deployed on a single flight. The company has organized the launch of 76 satellites previously, many through the Nanoracks dispenser operated from the International Space Station.
Spaceflight's new funding came from RRE Venture Capital, Vulcain Capital and Razor's Edge Ventures.
In a March 11 interview, Spaceflight Chief Executive Jason Andrews discussed his company's near-term satellite-deployment plans. He stressed that his company is scrupulous in ensuring that the satellites it helps launch respect international guidelines calling for low-orbit spacecraft to deorbit within 25 years to prevent the buildup of orbital debris.

How is demand for small satellite launches shaping up? 
We have upcoming missions this year and in 2016 and 2017. Demand is such that we're looking at potentially buying something as large as a Falcon 9 and doing a cluster mission. We would integrate dozens of spacecraft and take them to orbit.
The cheapest launch vehicle on the planet is around $40 million. All our customers have a budget of between $400,000 and $4 million to procure launch services.
We launch everything from a cubesat up to a 300-kilogram satellite for DLR, the German Aerospace Center. It's possible we could go bigger, because as long as people go rideshare, that's the market niche that we're focused on.

How does the Sherpa tug operate?
The Falcon 9 will deploy the primary payload and then go to an orbit that's different, but will meet the 25-year life lim it for the satellites. We get deployed as the Sherpa. It's a ring that we turn into spacecraft and have a series of dispensers that are mounts on each of the ports to deploy the 87 satellites.
On that mission we have a wide variety of nanosats, cubesats, microsats and minisats.

So the Sherpa carrier is deployed from the Falcon 9 and then governs its own deployment sequence?
Yes, we are a free-flyer. So SpaceX deploys two missions, the primary mission and then the Sherpa. And then we're up there and we conduct the mission and transmit the deployment of all the missions. The deployments happen within an hour. We transmit the telemetry back and then the payloads go on their way.

Then the Sherpa is disposed of?
Yes. We are looking at future missions at hosting payloads on it. We have some really interesting missions out here in 2016 and 2017 that not only go to low Earth orbit but also into deep space and potentially the Moon.

Is it fair to say there is no real launch bottleneck now for small satellites, that opportunities abound?
Sort of. You can look on our website and see all the flight opportunities we have. One of the common themes is that if you want to go to a sun-synchronous orbit, and specifically a 10:30 sun-synchronous orbit, there are a lot of flight options.
But if you want to go to any other orbit, for weather, for Internet delivery or other applications, and if you want to go to other latitudes, there are not very many secondary payload opportunities. But specifically to sun-synchronous orbit, there is a regular launch availability.

Is the Russian-Ukrainian Dnepr rocket still viewed as a reliable launch opportunity?
I am not sure if it's available. There is so much customer uncertainty that customers are wary. They don't know when it is going to fly.

What about India's PSLV vehicle, which apparently is now open for U.S. commercial satellites?
We are vehicle agnostic. If there is a vehicle going, we're talking to them — except for the Chinese because of political challenges. But for any country we can export spacecraft to, we are talking to them. As for PSLV, I can't be specific but we are working the manifest to get payloads on there.

Is there any room on the October Atlas 5 launch of Orbital ATK's Cygnus cargo capsule to the space station?
I do not know. We are working with a primary payload for an Atlas launch in 2016 on manifesting payloads that would go into orbit or even deep space. But we're not working on the one this year.

Who should be responsible for ensuring that all these small satellite owners have coordinated their radio frequencies, to the extent that they need to, and that they respect the 25-year-deorbit rule?
To launch from the United States you need a commercial launch license and part of that includes, I believe, an FCC approval or a NOAA approval. When we work with these secondary payloads, we need to get proof of that license as part of our submittal we give to the primary payload.
So some of that is done in the United States already. It may not be done for all foreign vehicles. I could be wrong but I think this is done in the U.S. I know that we vet that with our customers. Ultimately people are worried about hundreds or thousands of small satellites creating debris.
Ultimately it's in our interest to follow best practices or we're going to kill our own industry, and our own business. That's why we're so careful about the 25-year life lim it and careful about making sure the satellite owners do have their licenses — whether for imaging or transmission — especially when you have new actors coming into the market who may not be aware of all the regulatory issues.
We can also help them with the export licenses — there is a whole lot of stuff we do to help them get through the process.

But are you going to verify that 87 frequency-coordination filings have been OK'd with the FCC?
In order to launch 87 satellites on one launch you have to standardize things. I'll be honest: The world is changing very fast, and 87 satellites will be a new record but that doesn't mean there won't eventually be 150 satellites or even up from there.

One issue that came up at the ITU is the FCC's licensing regime, which seems excessive to some small-satellite owners. 
I am not aware of any coordinated program to ask the FCC to review this. But it's a lot to pay. I am not an expert, but maybe there could be sliding scale of fees depending on how much spectrum you were using. There are definitely ways to streamline it, and this is something that should be thought about.
I can imagine that they are trying to set a high bar so they only get serious people and avoid spectrum squatters. But there is probably some evolution that needs to happen in the licensing realm.

ЦитироватьSpaceX prepping for construction

By EMMA PEREZ-TREVIÑO Staff Writer | Posted 5 hours ago
HARLINGEN — Elon Musk's plans to develop the world's first commercial and vertical orbital launch complex at Boca Chica Beach in Cameron County are heightening with the near completion of its design and continuing land purchases.
Detailed design work for the proposed $100 million launch complex at Boca Chica, 17 miles east-northeast of the Brownsville South Padre Island International Airport and about 5 miles south of South Padre Island, is expected to be completed soon.
"I believe that construction activity at the SpaceX site will intensify in the near future as the design phase is completed and focus shifts to the construction phase," Cameron County Judge Pete Sepulveda said.
This also coincides with Musk's statement at the groundbreaking ceremony held in September that while advance preparation work toward construction of the complex would be underway, it would not be until this year when construction would begin in earnest.
These are among the developments of Space Exploration Technologies' increased activity on the heels of successful vendor fairs in Brownsville and McAllen, and the University of Texas System's imminent extension of high-speed communication services to the site.
As has been reported, SpaceX is in talks with local businesses following the recent vendor fairs.
As also can be gleaned, SpaceX's construction office at the site of the launch complex's command center has been established and is functional.
Furthermore, officials close to the project say that SpaceX is actively engaged in monitoring biological and environmental impacts as was noted would take place in the project's environmental impact statement.
In addition, job postings for critical positions in the development of the complex continue, as do land purchases, public records show.
More than 115 acres of land have now been purchased, public records show.
This year alone, nearly 10 acres were purchased. The purchases continue to be made through SpaceX's Dogleg Park LLC.
SpaceX plans to launch the Falcon 9 and Falcon Heavy orbital vertical rockets, which also could carry the Dragon capsule — and a variety of smaller, reusable suborbital launch vehicles from Boca Chica.

ЦитироватьUpcoming Launch Landing Configurations? (self.spacex)
KaneLSmith пишет:
I was wondering if anyone could spare some information on the upcoming launches and if they will be attempting landings afterwards. As I understand it, the Turkmensat - 1 launch will not be landing. Does anyone have information on the following Jason 3 and CRS launches?
EchoLogic пишет:
    [/li]
  • Turkmensat-1, no - too heavy and too much to take to orbit.
  • CRS-6, yes, barge landing.
  • CRS-7, yes, barge landing.
  • Jason-3, hehe. Secret inside info on this one. Y'all know where to find it.
  • CRS-8, maybe. Might be too heavy due to BEAM, but it also might be able to land back at launch site. They probably haven't planned this far out yet.
  • Orbcomm OG2, yes. Payload is lighter than Dragon and only going to LEO.
  • SES-9, no. Even with upgrades, stretching, densification, payload is far too heavy for a landing attempt. Should really be flying on a FH instead.
  • ABS & Eutelsat Mission 2, not sure. Nice light sats because they're electric, but positives are mitigated by the fact there's two of them and they might prefer to in
averagespacejoe пишет:

A few posts down it was clarified that yes SpaceX will attempt a landing on both CRS SpX-6 and CRS SpX-7. There is no solid confirmation on Jason but considering that is also a NASA mission and NASA has a huge interest in reuseability, and considering that reusability test have not been adverse to Dragon missions, I have a hard time seeing why they would object. Other than the fact that the second barge may or may not be ready in time which is more of an internal SpaceX thing.

ЦитироватьSpaceX Says Falcon 9 Upgrade Won't Require New Certification
by Peter B. de Selding — March 16, 2015

WASHINGTON — SpaceX President Gwynne Shotwell on March 16 said the company's introduction this year of a more-powerful Falcon 9, designed to permit the company to recover the rocket's first stage for future reuse, will not begin another long process of U.S. government certification.
Addressing the Satellite 2015 conference here, Shotwell said Hawthorne, California-based SpaceX still expects certification of its current Falcon 9 v1.1 rocket by the U.S. Air Force and NASA by the middle of this year.
For the improved-version rocket, now expected to make its first flight this summer carrying a commercial telecommunications satellite for SES of Luxembourg, the company's goal is to add between 15 and 20 percent to the current rocket's performance.
The current engine and fuel configuration does not carry the requisite power to carry a heavy telecommunications satellite to geostationary orbit while also reserving fuel to perform the landing on a SpaceX offshore platform.
Shotwell said about half of the certification issues being worked by the two U.S. government agencies relate to the company's specific practices in building its rockets, and not to any specific rocket design. Because of that, she said, the more-powerful Falcon 9 is unlikely to force a renewed certification process.
"It is an iterative process [with the agencies]," Shotwell said. "It will become quicker and quicker to certify" new versions of the vehicle.
The current certification process, which required a certain number of flights of the Falcon 9 v1.1, is needed for SpaceX to launch satellites for the U.S. military and NASA, starting with the Jason 3 U.S.-European ocean-altimetry satellite, to be launched later this year.

ЦитироватьSpaceX says boosting output, on track for 13 rocket launches this year
Reuters
By Andrea Shalal and Irene Klotz 18 hours ago

WASHINGTON (Reuters) - Space Exploration Technologies, or SpaceX, is rapidly increasing production of the engines that power its Falcon 9 rocket and expects to meet its target of 13 launches and two test flights this year, President Gwynne Shotwell told Reuters.

SpaceX, the technology upstart founded by entrepreneur Elon Musk, is stepping up hiring of engineers and other workers to help boost production, including many from other sectors such as the automotive industry and the military, company officials said.

This year, the company expects to produce at least 180 engines, with that number set to increase to 240 next year, and 400 in 2017, Shotwell told Reuters in an interview late last week.

Shotwell said increasing production put the company on track to complete 13 launches this year. It fell short of its targets last year due to a number of factors.

"Certainly from a manufacturing perspective, we should be able to meet those targets," said Shotwell, who is due to testify before the House Armed Service Committee on Tuesday about a drive to end U.S. reliance on a Russian-built engine that powers one of two rockets used by SpaceX rival United Launch Alliance (ULA).

The Air Force expects to certify SpaceX by June to launch some military and intelligence satellites using its Falcon 9 rockets. Currently, those satellites can only be launched by ULA, a joint venture of Lockheed Martin Corp and Boeing Co, the two largest U.S. arms makers.

SpaceX has shaken up the satellite industry in recent years, winning a variety of launch contracts from commercial firms, as well as NASA, and putting pressure on ULA to lower its costs. But skeptics say the jury is still out on whether SpaceX can keep up with rising demand and growing backlog.

SpaceX has already launched three times this year and is gearing up for a fourth launch on March 21, followed by a cargo resupply mission for NASA in early April.

The company also has a prototype crew capsule at Cape Canaveral for a test flight to prove that a spaceship carrying astronauts could safely abort a mission if a rocket blew up on the launch pad, she said.

SpaceX plans a second test flight this year for NASA, aimed showing its ability safely land astronauts if a launch was aborted during flight.

Shotwell said the company was also making "great progress" on its 27-engine Falcon Heavy rocket, and planned to test it later this year at a refurbished space shuttle launch pad at Kennedy Space Center in Florida.

1. ЦБ Falcon Heavy
2. Боковушка Falcon Heavy / Falcon - 9

ЦитироватьSo, we got the higher thrust engines, finished development on that, we're in qual. What we're also doing is modifying the structure a little bit. I want to be building only two versions, or two cores in my factory, any more than that would not be great from a customer perspective. So Falcon Heavy is two different cores, the inner core and then the two side boosters, and the new single stick Falcon 9 will basically be a Falcon Heavy side booster. So, we're building two types of cores and that's to make sure we don't have a bunch of different configurations of the vehicle around the factory. I think it will streamline operations and really allow us to hit a cadence of one or two a month at every launch site we have.

О различии в размерах ББ и ЦБ ФХ известно уже около года. Если оптимизировать проектные параметры, то есть тенденция к увеличению массы ПГ при увеличении РЗТ в ББ относительно ЦБ. Поэтому ББ имеют емкость объем баков процентов на 15 больше, чем в ЦБ.

Но поскольку это различие проявляется лишь в длине, то никаких проблем с оснасткой не возникает.

http://www.nasaspaceflight.com/2015/03/spaceport-america-spacex-reusability-testing/
ЦитироватьThe original plan was to use the site for test flights of the second F9R Development Vehicle, known as F9R Dev2, a follow on vehicle from the impressive Grasshopper and F9R Dev1 vehicles that paved the way for the propulsive landing attempts.

Those vehicles were tested at SpaceX's McGregor test site in Texas, but were restricted by an altitude ceiling, resulting in the decision to conduct tests at Spaceport America, at much greater altitudes.

Now, based on the advances made during recent missions, it appears SpaceX is hoping to promote the role of Spaceport America, specifically to put the first recovered stage through its paces.

Those tests will be used to find hardware limits, such as how many cycles can be put on a stage, while the second successfully recovered booster would provide the role of qualification testing.

Should the recovery efforts progress, the first launch of a reused booster is likely to occur in late 2016.

Another major milestone in the reusability path will be a stage returning to land, with the earliest planned attempt – should all testing go to plan ahead of the mission – being the Jason-3 launch in the summer.

This would result in the stage returning for a landing at SLC-4 at Vandenberg Air Force Base in California. This will be at the mercy of SpaceX's confidence levels, and a second ASDS, based on the West Coast, has already been confirmed.

SpaceX is also planning to land stages on the East Coast, at Cape Canaveral's SLC-13.

Returning to land is not only important to SpaceX for the eventual turnaround flow schedules, but it also mitigates the loss rate expected from landings involving sea recovery, not least due to weather variables associated with the ASDS.

These advances will then feed into SpaceX's Falcon Heavy rocket, which will be aiming to return three cores per mission. Technically, it has been argued, that returning all three cores from Falcon Heavy flights could result in the rocket becoming cheaper to operate than an expendable Falcon 9.

Если все будет хорошо этим летом во время миссии Jason-3 будет предпринята попытка посадки на землю.
