И кто за всё это будет платить? Это же сотни миллионов долларов

Ну пару сотен всегда можно найти. Мой штат заплатил примерно столько за космодром для Сэра Ричарда, а ведь мы в 20 раз беднее Техаса.

Т.е. администрация штата заплатила только надеясь на развитие и не ожидая выгоды прям завтра?

Скупой платит дважды! (С)

А можно попросить ссылочку по поводу  финансирование космодрома для сера Ричарда. У нас тут дискуссия была на счет частника, который себе инфраструктуру сам обеспечивает. И как пример приводился сер Ричард.  :roll:

Цифра в 209 фактических миллионов "до полного завершения" много где встречается, например тут:
http://www.nytimes.com/2011/02/24/us/24spaceport.html?_r=1

Понятно, что задержки проэкта означают постоянную накрутку ввиду того, что нужно платить хотя бы вахтеру. Сейчас им урезали фонды до 500 тыс. в год, что, вместе с 200 тыс. ор Сэра Ричарда, означает примерно 2 вахтера, 2 бюрократа в Лас Крюсесе и 2 в Санта Фе. Остальные бюрократы проедают остатки "разработочных" 209 миллионов.

Да, я считаю, что это был просчет. У Маска по крайней мере хоть что-то уже летает, хотя у него тоже задержки в годы. Заметим, что под Сэром Ричардом жители 3-х местных графств сбились в кучу и согласились увеличить свои налоги на продажу на полцента. Я против этого ничего не имею, можно сказать демократия в действии. К сожалению, я не в курсе сколько они набирают в год. Думаю, что около 150 тысяч.

Details Emerge on SpaceX's Proposed Texas Launch Site

WASHINGTON — Details about a launch facility Space Exploration Technologies Corp. (SpaceX) is considering building in Texas emerged April 9 in a Federal Aviation Administration (FAA) document detailing an environmental review that must precede construction.

The proposed launch site would be used "to launch orbital and suborbital launch vehicles from a private site in Cameron County in southern Texas," according to the FAA's notice of its intent to prepare an environmental impact statement. All launches from the proposed spaceport would fly east over the Gulf of Mexico, the document said.

The proposed facility would be built to handle up to 12 commercial launches a year and would support SpaceX's Falcon 9 medium rocket and the company's planned Falcon Heavy launcher for which SpaceX has no paying customers. Falcon 9 launches from the proposed facility would include launches of the Dragon space capsule, which SpaceX plans to begin launching this year from Cape Canaveral Air Force Station, Fla., to fly cargo to the international space station under a $1.6 billion contract with NASA.

The FAA document is to be printed in the federal register on April 10, according to a prepublication copy posted on federalregister.gov.

"SpaceX is considering multiple potential locations around the country for a new commercial launch pad," SpaceX spokeswoman Kirstin Grantham told Space News April 9. "The Brownsville area is one of the possibilities, but there is a long way to go before this could happen."

FAA spokesman Hank Price did not immediately reply to a request for comment.

In November, SpaceX Chief Executive Elon Musk, said the Hawthorne, Calif.-based company wants to build a launch site that functioned "like a commercial Cape Canaveral." SpaceX said then that the company was considering sites in Alaska, California, Florida, Texas and Virginia.

Grantham would not say whether SpaceX had ruled out any of these locations as possible launch sites, nor whether the company had zeroed in on Texas as the site of its proposed commercial launch facility. Currently, SpaceX has launch infrastructure at Cape Canaveral and Vandenberg Air Force Base, Calif. When it was still marketing the single-engine Falcon 1, SpaceX launched that rocket from Omelek Island in the Kwajalein Atoll. The company also has a rocket test facility in McGregor, Texas, which is about 690 kilometers north of the proposed Brownsville launch site.

If SpaceX does decide to launch from the Brownsville area, the company would have to build a new vertical launch facility, a control area and a payload integration facility, according to the FAA document.

"The proposed vertical launch area site is currently undeveloped and is located directly adjacent to the eastern terminus of Texas State Highway 4 (Boca Chica Boulevard) and approximately 3 miles [5 km] north of the Mexican border on the Gulf Coast," the FAA document says. "It is located approximately 5 miles [8 km] south of Port Isabel and South Padre Island."

All spaceport facilities would be on private land owned or leased by SpaceX, although some support facilities could be located off of SpaceX property, the document said.

Besides orbital spacecraft, the Texas site would also support "a variety of smaller reusable suborbital launch vehicles," the document said. That could include SpaceX's Grasshopper vehicle, a test bed for reusable rocket stages comprising a Falcon 9 core stage fitted with landing gear.

SpaceX considers South Texas for private launch site

SpaceX is examining a prospective launch site in South Texas for commercial Falcon rocket missions and testing of reusable suborbital boosters, but the company has not made the final selection of a location for a privately-owned launch base, a company spokesperson said Tuesday.

The Federal Aviation Administration issued a notice it will prepare an environmental impact statement for the site, which is located in Cameron County, Texas. The notice was published in the Federal Register on Tuesday.

If built, the facility would host up to 12 launches per year, including flights of SpaceX's Falcon 9 and Falcon Heavy launch vehicles and tests of reusable suborbital rockets, according to the FAA notice.

The notice says the proposed launch site would be on privately-owned land and consist of a vertical launch area and control center. It is located adjacent to the eastern terminus ot Texas State Highway 4, about 3 miles north of the Mexican border, 5 miles south of Port Isabel and South Padre Island, and 20 miles east of Brownsville.

"SpaceX is considering multiple potential locations around the country for a new commercial launch pad," said Kirstin Brost, a SpaceX spokesperson. "The Brownsville area is one of the possibilities."

Elon Musk, SpaceX's founder and CEO, told Spaceflight Now in November the company is evaluating commercial launch sites in Florida, Texas, Hawaii and Puerto Rico.

The commercial launch facility needs to be on U.S. soil to comply with arms export regulations, Musk said.

SpaceX has an operational launch pad at Cape Canaveral Air Force Station, Fla. A launch pad for polar-orbit Falcon launches is under development at Vandenberg Air Force Base, Calif. Both facilities sit on retired pads used by the Titan 4 rocket.

"The Cape and Vandenberg are great for U.S. government launches, but not well optimized for commercial," Musk said in November. "Just as it makes sense to use commercial airports for commercial air flights, I think the same principle applies to rockets."

SpaceX says launches for government customers would continue to occur from Cape Canaveral and Vandenberg.

SpaceX has not set a date for the opening of a commercial launch base, but construction of a new site would take several years. The FAA notice did not include a timeline for the completion of the environmental impact statement.

Launches from the proposed Cameron County base would fly east over the Gulf of Mexico, according to the FAA.

"Operations would consist of up to 12 launches per year with a maximum of two Falcon Heavy launches," the notice said. "All Falcon 9 and Falcon Heavy launches would be expected to have commercial payloads, including satellites or experimental payloads. In addition to standard payloads, the Falcon 9 and Falcon Heavy may also carry a capsule, such as the SpaceX Dragon capsule."

Powered off the ground by 27 liquid-fueled Merlin engines, the Falcon Heavy is scheduled to launch as soon as 2013 on a test flight from Vandenberg. Fully fueled and assembled for launch, the Falcon Heavy will weigh 3.1 million pounds and stand 227 feet tall, according to SpaceX.

The Falcon 9 rocket has successfully launched twice, and its third flight is scheduled for no earlier than April 30 with a Dragon spacecraft bound for the International Space Station.

Suborbital flights at a commercial site could include SpaceX's Grasshopper vehicle, a testbed for a reusable orbital launcher. The Grasshopper will fly initial low-altitude missions from SpaceX's rocket testing grounds in McGregor, Texas, between Dallas and Austin.

Gwynne Shotwell, SpaceX's president, declined to comment in an interview last month on when Grasshopper flights could begin.

"SpaceX is considering multiple potential locations around the country for a new launch pad for commercial payloads. The Brownsville area is one of the possibilities," SpaceX spokeswoman Kirstin Brost Grantham wrote in an email.

The other contenders are Puerto Rico, Hawaii and Florida, she added.

The company is one of two hired by NASA to deliver cargo to the space station. It also plans to upgrade the Dragon capsule to fly astronauts as well.

Rockets launched from the proposed Brownsville site would fly east over the Gulf of Mexico.

Нормально. Пока Фалькон не летал, он стоил ну очень дешево. Но сейчас Фалькон "Накануне", и его ценник всего на 10% ниже, чем расценки "Союза". После начала регулярных полетов выяснится, что есть ракета, на которой можно запустить свой спутник по ценам "Союза", и не вывозя спутник за границу.

Следующий этап - снизятся цены на Союз. Но и Маск снизит свою цену. Вы уверены, что в этой ценовой войне выиграет Союз? А я очень сомневаюсь.

Не сомневайтесь. Имейте в виду - продажная цена Союз-2 по отношению к себестоимости имеет чудовищный лаг. И этот лаг можно подсмотреть в интернете.
Сейчас цена Союза - это Союз-2-1б с новой третьей ступенью и новой СУ. Т.е. это во многом новая РН которая пока на этапе ЛКИ. Завершение ЛКИ, наработка статистики, принятие на вооружение, снятие с производства ФГ и У, увеличение серийности, нажим РККЭ на зарвавшихся Кирилина и Ахмедова, сокращение ЦСКБ накладных расходов - и себестоимость 2-1а и 2-1б падает вниз как в оборвавшемся лифте..
Еще. Цена Союз - это РН Союз плюс РБ Фрегат. Союз без Фрегата стоит еще дешевле.
А вот про Ф-9 ничего такого сказать нельзя. Например - мы знаем заявленную продажную коммерческую цену на 2012 - 54 млн.
А какова себестоимость? Нигде не найти. Если я скажу что Маск пытается продавать Ф-9 по себестоимости - Вы не сможете мне возразить.
Получается - мордорские орки которые продают Союз более открыты чем эльфы которые продают Ф-9 и эти орки имеют больший запас прочности для снижения коммерческой цены.

Spaceflight Formally Launches SHERPA and Announces Flight Schedule[/size]
By Keith Cowing
Posted May 7, 2012 1:27 PM





Spaceflight Inc. (Spaceflight) unveiled today its SHERPA in-space tug, which is dedicated to hosting and deploying small and secondary payloads.


"SHERPA is the next step in providing space access for small and secondary payloads," said Jason Andrews, President and CEO of Spaceflight Inc. "SHERPA builds on our Spaceflight Secondary Payload System (SSPS) by incorporating a propulsion and power generation system to allow us to host payloads, as well as place them in an orbit other than the primary payload's orbit."

SHERPA is a three-axis stabilized platform with over 400 meters per second of on-orbit maneuvering capability. SHERPA can provide over 100 Watts of power to hosted or secondary payloads and can be upgraded to meet specific customer power, propulsion and pointing requirements.

Spaceflight has been working with its sister company, Andrews Space (Andrews), since 2010 to develop the SSPS and SHERPA family to meet its business requirements. Andrews will fabricate the SSPS and SHERPA at its recently expanded facility in Tukwila, WA.

"We've seen strong demand for our SSPS and secondary payload launch services," continued Andrews. "However, one of the limitations has been that a portion of the secondary payload market requires going to a different altitude than that of the primary payload. SHERPA is designed to address this requirement, as well as expand our offering of services to include hosted payloads."

Spaceflight's first demonstration mission of SHERPA will occur in early 2014, with the first commercial mission scheduled for late 2014. Both missions will be carried to sun synchronous orbits on SpaceX Falcon 9 rockets. Both missions are planned for launches to sun synchronous orbits on SpaceX Falcon 9 rockets.

"We strongly believe in the utility of small satellites and support Spaceflight's efforts to nurture this emerging market segment," said Gwynne Shotwell, President of SpaceX.

Information on the SSPS and SHERPA systems, as well as the latest manifest and mission pricing, can be found on Spaceflight's website at: www.spaceflightservices.com.

About Spaceflight Inc.

Spaceflight Inc. was established in 2009 by Jason Andrews, President and CEO of Andrews Space, to revolutionize secondary payload flight services for fixed and deployable cargo and transport. More information about Spaceflight and specific flight opportunities can be found on the company's website: www.spaceflightservices.com

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. For more information about NASA and agency programs, visit:

F9 v1.1 видимо новое название для Block 2.
Похоже изменилась компоновка двигателей в ДУ первой ступени.
Кроме того резко уменьшился межступенчатый переходник, что может быть связано с укорочением сопла Merlin Vac, или с появлением тороидального бака на  второй ступени.

http://forum.nasaspaceflight.com/index.php?topic=28882.msg897156#msg897156

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.

http://forum.nasaspaceflight.com/index.php?topic=28882.msg897204#msg897204

Per a request, here's a comparison between the old Falcon 9 Heavy length, the extrapolated height and tank stretches at the time of Falcon Heavy announcement last year and the new drawing scaled to the extrapolated 69 meter height.

Zenit is there for reference.

http://forum.nasaspaceflight.com/index.php?topic=28882.msg897399#msg897399

Has a very high probability of being artistic license/error from where I'm sitting. I can't see how you could arrange 9 Merlins under the Falcon 9's first stage in any configuration without needing fairings, let alone an octagonal plan with a wide middle space for a gimballing center nozzle. The current 3x3 is a pretty tight pack and the corner engine bells still stick out a fair bit from the tank sidewalls, hence fairings.

Just a quick drawing with estimated M1D nozzles.  Spacing is very close and would probably need all to gimbal together to keep them from touching.  Center engine has plenty of space to gimbal alone without touching the outer engines.
