Какой смысл отрабатывать посадку на макете, когда это можно делать в реальных полетах. В этих условиях Кузнечик и его производные - лишь напрасная трата времени и денег.
Само собой понятно. Меня просто забавляет, что после стонов скептиков по поводу проблемности посадки реальная ее сложность, похоже, оказалась ниже даже изначальных SpaceX-овых оценок.
Предполагаю, они думали что с первым этапом посадки проблем будет больше.
То есть вы на глазок можете определить сложность посадки даже не имея оной? КрутЫ, конечно. На мой непросвещенный взгляд пока что было удачное попадание в угол платформы с полным разрушением одного из четырех приводов. Для "морского боя" - попал. :) В видео, процитированном Дмитрием В видно как ступень идет вниз под углом компенсируя ветровой снос, но "к несчастью" камера теряет ее из виду в самый пикантный момент - момент выравнивания (ветер никто не выключал).

Нет. Но мне и не нужно. Я могу оценить уверенность SpaceX-а в оценке этой сложности, а она явно очень, очень высока. Потому что одно дело "мы щас ее посадим, мамойклянус!", а другое - "мы отменяем сложную поступенчатую программу которая  в конечном счете почти гарантированно даст нам достаточно данных для успеха, да плюс еще попутно позволит отработать само переиспользование - тоже плавно и не торопясь."
Причем решение было, похоже, принято после последней посадки в шторм. Не раньше, несмотря на реки оптимизма.
Они явно совершенно  железобетонно уверены в том, что посадят. И это не показуха. Для показухи резать Кузнечика было незачем. Есть, конечно, шанс что они ошибаются, но, думаю, при такой уверенности он достаточно небольшой.

Все довольно хорошо видно и достаточно, чтобы сделать вывод о мягкой посадке.

Дмитрий В., видео последней посадки нет. Тот ролик, который вы предоставили, им не является. Когда ракетой попали в баржу, Маск тоже утверждал поначалу, что ракета попала "почти вертикально". На видео этого не было. Нежелание публиковать последнюю посадку говорить может о сокрытии проблем каких-либо.

SES reserves two Falcon 9 launches fr om Texas
Posted on February 25, 2015 by Stephen Clark

Two communications satellites owned by SES are booked to fly into orbit from South Texas on a pair of Falcon 9 rockets in 2017, giving SpaceX its first two confirmed payloads assigned to launch from the new commercial spaceport, officials said Wednesday.
SES announced SpaceX’s Falcon 9 rocket will launch the two satellites — SES 14 and SES 16/GovSat — nine days after the company unveiled an order for three spacecraft to be manufactured by Airbus Defense and Space, Boeing Satellite Systems and Orbital ATK.
Officials said Wednesday the Airbus-built SES 14 satellite and the SES 16/GovSat spacecraft produced by Orbital ATK will launch on two Falcon 9 rockets in 2017. Launch services for the SES 15 satellite made by Boeing have not been disclosed.
“SpaceX is an important launch partner to realize our new fleet investment and growth programme,” said Martin Halliwell, chief technology officer of SES. “With SpaceX, we share the mission of innovating the space segment and technology, achieving step changes in the design and economics of launchers, and leveraging them to the advantage of our satellites, their profile, flexibility and performance, and, above all, our customers. We are looking forward to working with the SpaceX team on these two new missions.”
Based in Luxembourg, SES is the largest satellite operator in the world as measured by revenue.
Industry officials familiar with the launch deal said both satellites are planned to lift off from SpaceX’s new launch site at Boca Chica Beach near Brownsville, Texas.
It was not clear whether another commercial SpaceX launch could occur from the Texas spaceport before the SES 14 and SES 16/GovSat missions are ready for liftoff in 2017.
SpaceX chief executive Elon Musk said at a September groundbreaking for the South Texas spaceport that the first launch from the facility was expected no earlier than late 2016.

The commercial launch site is one of the first of its kind, operating under the licensing authority of the Federal Aviation Administration, which holds responsibility for public safety. The U.S. Air Force has that job at SpaceX’s current launch sites at Cape Canaveral, Florida, and Vandenberg Air Force Base, California.
Musk said SpaceX plans to move many of its commercial satellite launches into geostationary transfer orbit to the South Texas site, which sits on the Gulf of Mexico about 20 miles east of Brownsville and three miles north of the U.S.-Mexico border.
“Our preference is to try to move particularly the commercial GTO (geostationary transfer orbit) missions to the Boca Chica launch site as soon as we can because there’s a significant benefit by being south,” Musk said.
Geostationary transfer orbit — an elliptical orbit with a high point typically about 22,300 miles above Earth — is a common drop-off point for large communications satellites.
Communications satellites use on-board thrusters to circularize their orbits at geostationary altitude — 22,300 miles — and move over the equator, wh ere their orbital velocity matches the speed of Earth’s rotation, causing the spacecraft to hover over a fixed location on the planet.
Rockets launching into such orbits receive a performance boost from launch pads at lower latitudes because of the faster spin of Earth closer to the equator. Launching closer to the equator allows rockets to use less fuel to put satellites in orbit.
“We’re two-and-a-half degrees south of Cape Canaveral, and those two-and-a-half degrees are actually helpful for GTO missions,” Musk said. “We have a strong incentive to try to get Boca Chica active as soon as possible.”
The Boca Chica launch site lies at about 26 degrees north latitude, while Cape Canaveral sits at approximately 28.5 degrees.
SpaceX’s rockets will launch to the east from Boca Chica Beach, flying over the Gulf of Mexico and the Florida Straits between the Florida Keys and Cuba to avoid flying over land en route to geostationary transfer orbit with commercial satellites.
The SES 14 satellite assigned to launch with SpaceX will carry C-band, Ku-band and Ka-band payloads to cover the Americas and the North Atlantic with direct-to-home television programming and mobile, maritime and aeronautical communications. The spacecraft is based on the Eurostar E3000e platform from Airbus, and its all-electric propulsion system will place the satellite into a circular operating orbit a few months after launch.
According to an Airbus press release, SES 14 will weight about 4,200 kilograms — 9,259 pounds — at launch.
SES 14 will be positioned at 47.5/48 degrees west longitude, wh ere SES says it will replace and expand capacity currently provided by the NSS 806 satellite launched in February 1998 by an Atlas 2AS rocket.
The SES 16/GovSat mission is a partnership between SES and the government of Luxembourg, which formed a joint company named LuxGovSat. Luxembourg has committed to purchasing a significant amount of capacity on the SES 16/GovSat satellite in support of its NATO obligations, according to SES.
Built on Orbital ATK’s GEOStar 3 medium-class satellite bus, the spacecraft will be parked in geostationary orbit at 21.5 degrees east longitude for a 15-year mission, working in military frequencies in X-band and Ka-band reaching users in Europe, Africa and the Middle East.

SES Books Falcon 9 Launches for Two Newly Ordered Satellites
by Peter B. de Selding — February 25, 2015

PARIS — Satellite fleet operator SES on Feb. 25 said two of the three satellites it ordered the previous week will be launched aboard SpaceX Falcon 9 rockets in 2017.
Luxembourg-based SES, which was the first established commercial satellite fleet operator to use Falcon 9 and has another launch scheduled with SpaceX this summer, said its SES-14 and SES-16/GovSat satellites would be launched on separate Falcon 9 vehicles.
SES-14, under construction by Airbus Defence and Space of Europe, is expected to weigh 4,200 kilograms at launch. SES-16/Govsat – owned by a joint venture between SES and the Luxembourg government set up to sell X- and military Ka-band capacity to allied governments – is being built by Orbital ATK of Dulles, Virginia, and is expected to weigh less than 4,000 kilograms.

SES-16/GovSat

SpaceX rival Arianespace of Europe did not bid on either launch because both satellites are too heavy to fit into the lower position of the Ariane 5 rocket given the heavier upper-berth passengers that Evry, France-based Arianespace has booked for 2017.
An SES official confirmed that Arianespace did not bid for either of the two contracts. Satellites in the 4,000-kilogram class have limited launch options in today’s market.
SES ordered a third satellite, SES-15, at the same time as the other two. It is a Boeing 702SP spacecraft built by Boeing Space and Intelligence Systems of El Segundo, California and is expected to weigh less than either of the others.
Because of that, Arianespace is competing for the launch, also scheduled for 2017, industry officials said.

SpaceX Gets “Partial Win” in Blue Origin Patent Dispute
by Jeff Foust — March 5, 2015

WASHINGTON — A patent board offered SpaceX a split decision on its protest of a reusable launch vehicle patent held by Blue Origin, approving a review of some, but not all, claims of that patent.
In separate decisions issued March 3, the U.S. Patent and Trademark Office’s Patent Trial and Appeal Board approved a SpaceX petition for an “inter partes” review of 13 of the 15 claims in a patent governing the landing of reusable launch vehicle stages on ships or other platforms in bodies of water.
The board concluded Blue Origin’s description of turning off and then reigniting the booster’s rocket engines was too vague for the board to decide if SpaceX had a “reasonable likelihood” of winning a review.
“On the current record, SpaceX has demonstrated a reasonable likelihood of prevailing on the asserted ground of anticipation” of the first 13 claims of the patent, the board concluded in its ruling. “As such, we authorize institution of an inter partes review of claims 1–13 of the… patent.”
The board, though, denied SpaceX’s petition for a review of the final two claims of Blue Origin’s patent, which cover the powered landing of part or all of a launch vehicle on a “sea going platform” and then reusing that vehicle. The board concluded that Blue Origin’s description of turning off and then reigniting the booster’s rocket engines was too vague for the board to decide if SpaceX had a “reasonable likelihood” of winning a review on those two claims.

While initial reaction to the board’s decision focused on its rejection of SpaceX’s petition, one attorney called the rulings a “big day” for SpaceX. “This is a partial win for SpaceX,” said Andrew Rush, a Jacksonville, Florida-based lawyer who studies intellectual property law as applied to space, in a series of tweets about the board’s decision March 4.
In a March 5 interview, Rush said that the board’s conclusion that the language in two of the claims is “indefinite” could allow SpaceX to challenge the patent in federal court, or provide a strong defense should Blue Origin sue SpaceX for patent infringement. Claims that use indefinite language are considered invalid, he said.
“They lost the battle,” Rush said of SpaceX and its denied petition, “but they were told they would win the war.”
At the heart of the dispute is U.S. Patent 8,678,321, titled, “Sea landing of space launch vehicles and associated systems and methods” and awarded to Blue Origin in March 2014. The patent covers methods of landing and recovering portions of launch vehicles on platforms located at sea or other bodies of water. Blue Origin filed the patent application in June 2010.
While Blue Origin has not indicated if or when it would use such a recovery system for its vehicles, SpaceX is already using this approach as it develops a reusable version of its Falcon 9 rocket.
In January, a Falcon 9 first stage crashed on the deck of SpaceX’s “autonomous spaceport drone ship” after a launch from Cape Canaveral. The stage ran out of hydraulic fluid used to manipulate fins on the stage, preventing a controlled landing on the ship’s deck.
SpaceX planned to make another landing attempt during a February launch, also from Cape Canaveral, but heavy seas in the Atlantic Ocean forced the company to withdraw the ship from the landing site. SpaceX later said the stage touched down on the ocean surface within ten meters of its target. SpaceX is expected to make another landing attempt on its next launch of a space station cargo resupply mission, scheduled for April.
SpaceX filed a petition for inter partes review with the U.S. Patent and Trademark Office in August 2014, citing prior art that it argued invalidated Blue Origin’s patent. That included 1998 papers by Japanese inventor Yoshiyuki Ishijima, published by the American Institute of Aeronautics and Astronautics, which show a process for landing a stage at sea in a manner similar to what Blue Origin described in its patent.
Under the current inter partes review system for patents, established by the America Invents Act of 2011, the Patent Trial and Appeal Board has 12 months to conclude its review, a clock that started with its March 3 decision to proceed with the review on some of the claims. That review can be extended for six months for “good cause,” according to an explanation of the process published by the Patent and Trademark Office.

US 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)

Spaceflight Industries Raises $20 Million

PARIS — Small satellite manufacturer and launch service coordinator Spaceflight Industries on March 11 said it had raised some $20.74 million in equity fr om three venture-capital companies and would use the money to double its staff by the end of the year.

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.

SpaceX 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.

Upcoming 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:
  • 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.
