$36 млн. за Пегас.

Понял, благодарствую. 90 тыс. долл за 1 кг - это стоимость обычного космодромного пуска.

Союз с Фрегатом выводит на аналогичную орбиту тонны четыре. Неужели его запуск стОит 360 млн?

Посмотрел статью о фотонной ракете. Если не дожариваться до орфографических ошибок почти в каждом предложении, то в сути идеи не рассматривается сам исходный источник энергии, который бы вызывал направленную эмиссию фотонов, а это как раз самое важное.

С такой ценой любой проект прогорит синим пламенем, и не зависимо от габаритов ПН.
100 кг, это далеко не наноракета!

Так как стенки-зеркала сосуда непроницаема для ИК фотонов, которые при нагревании излучают ионы

Это что?

[Аполлон Сидоров]

Зеркальные стенки меняют траекторию потока фотонов. Что именно является самим источником фотонов, причём в масштабном объёме?

Demand for CubeSat Deployments Nearing Space Station Limit

[Via Satellite 02-26-2014] The use of the International Space Station (ISS) as a platform for launching CubeSats has grown so much that the station crew may have to adjust their approach to keep pace. The most recent load of 33 satellites fr om Planet Labs, NanoSatisfi, SkyCube and others currently under way is now more than half way through deployment, and future launches to the ISS are already filling up. The demand for these launches has exceeded the expectation of NASA, JAXA and the commercial companies involved.

"This is our first deployment of CubeSats from the station using our own hardware," said Jeffrey Manber, CEO of NanoRacks. "We launched one CubeSat in 2013, and we projected to our investors that we should do three to five satellites this year," he said, laughing slightly at how far off they were. "We expect if all goes well to do 100 this year."

To date, NanoRacks has launched 150 payloads. The company used eight deployers to launch 16 CubeSats from the current load, 28 of which come from Planet Labs. The second round of deployments is currently underway. These spacecraft were delivered as secondary payloads onboard Orbital Sciences' commercial resupply services (CRS) Orb 1 mission. Astronauts on the ISS have been busy deploying the satellites, and NanoRacks has two to three more payloads planed for this year alone.

"You come up against the limits of the station," said Manber. "That's something we are talking to NASA about right now."

The demand for these launches comes from a variety of sources in percentages that are not expected. While schools are known for having CubeSat programs, they do not make up the majority of CubeSat users.

"Until this service from NanoRacks came along, everyone assumed it was academic," said Manber. "The shock of Planet Labs was that they are commercial. That is getting all sorts of publicity. We are seeing very strong interest from commercial companies ... second is U.S. government research satellites, and third is academia. And that is exactly opposite of what most people thought two years ago."

Phil Brzytwa, business development manager at Spaceflight Inc, a company that helps match satellites to launch vehicles, has noticed the same trend.

"The demand for CubeSat launches is steadily increasing, not just from universities and government programs, but from commercial entities as well," he said. "This growth extends outside of the U.S. and Europe to countries that are developing space programs."

Small satellites are a compelling route to space for countries that have new space programs. As more nations get involved — often with smaller budgets — CubeSats are becoming a cost-effective option to reach national priorities in space. According to Manber, the company is close to signing its first South American customer. Other customers include Romania, Vietnam, Saudi Arabia, Israel and Denmark.

"Two markets are coming of age here," said Manber. "Small satellites are truly coming of age, and so too the use of an orbital platform for service."

To continue to grow, NanoRacks is working with NASA and JAXA to evaluate new options. By demonstrating that the company's hardware works, they are opening up doors for greater space station utilization.

"They really are cognizant that this is a commercial business, and we've started talking with the space station program people about 'how do we grow? Can we get to 200 satellites? Can we get to 300? Can we get propulsion, and can we get to higher orbits?'" said Manber. "These are questions we are all asking now."

Anticipating that small satellites mark the beginning of an important industry, Manber expects other options for deployment to develop. Spaceflight Inc. is working with NanoRacks to provide more desired launch opportunities.

"For the commercial sector we see 400 kilometers and 52 degrees as a great location for customers seeking technology demonstration, but the altitude and inclination does not always meet mission needs, so Spaceflight can also help NanoRacks customers that want a higher altitude or inclination through our network of launch service providers," said Brzytwa.

Alternative methods, including ground-based dedicated small-sat launchers, would come as no surprise as this market develops. According to Brzytwa, Spaceflight Inc. expects existing launch service providers to pay more attention to small satellites as a way to increase profitability and to maximize the use of their vehicles. While NanoRacks may find some of these developments helpful, others would certainly be competition. For now, the company's primary focus remains on opening up space through the efficient use of the ISS.

"I think the future will hold strong competition and multiple opportunities," said Manber. "How much further can this market grow on station? Well, we've got some tricks up our sleeve we are working on at NanoRacks and we'll see what happens."

По поводу запуска спутников с МКС, используя NanoRacks.

Кстати, "забавный" поворот в истории с нанолаунчерами: Orbital, несмотря на наличие у них носителя для кубосатов, доставляет их пачками на МКС с помощью среднего носителя. Невидимая рука рынка?

Boeing Targets 66 Percent Launch Cost Reduction with ALASA  
By Mike Gruss | Mar. 28, 2014

WASHINGTON — Boeing Defense Space and Security of Huntington Beach, Calif., has won a three-way competition for a Pentagon contract worth as much as $104 million to build and demonstrate a low-cost, airborne satellite launching system, according to a March 24 posting on the Federal Business Opportunities website.
The contract is for the U.S. Defense Advanced Research Projects Agency's Airborne Launch Assist Space Access (ALASA) program, which is intended to field a system to launch satellites weighing up to 45 kilograms into low Earth orbit for as low as $1 million each.
Part of a broader DARPA effort to reduce the cost and turnaround time of national security space launches, ALASA seeks to use a rocket launched from modified fighter-jet aircraft taking off from a standard airport runway. Doing so, they argue, would allow the Defense Department to launch from almost anywhere, whereas currently space launches are restricted to just a few sites: Cape Canaveral Air Force Station, Fla.; Vandenberg Air Force Base, Calif.; Wallops Flight Facility, Va.; and Kodiak Island in Alaska. 
The ALASA rocket, measuring 7.3 meters long, would be attached to the underbelly of a Boeing-built F-15E fighter aircraft. Once the plane reaches an altitude of approximately 12,000 meters, the rocket would be released and then ignite to carry its payload to orbit.
The launch scheme is similar to that of the Pegasus XL air-launched rocket, which was developed by Orbital Sciences Corp. — also under a DARPA program — and is carried aloft by a modified Lockheed L-1011 aircraft. Although it became an established rocket, the Pegasus XL proved more expensive than anticipated and is seldom used these days.
In a March 29 press release, Boeing said its aim is to reduce the cost of launching microsatellites by 66 percent.
"We developed a cost-effective design by moving the engines forward on the launch vehicle. With our design, the first and second stages are powered by the same engines, reducing weight and complexity," Steve Johnston, Boeing's director of advanced space exploration, said in a March 28 press release.
The base value of Boeing's cost-plus fixed-fee, 11-month contract is $30.6 million, with a first option worth $72 million and a second option worth $2 million, according to the Federal Business Opportunities posting. Work is expected to be completed by Feb. 20, 2015, the posting said.
In 2012, DARPA awarded ALASA design contracts to Boeing, Lockheed Martin — which proposed launching from an F-22 aircraft — and Virgin Galactic, the space tourism outfit that is now testing an air-launched, passenger-carrying suborbital vehicle dubbed SpaceShipTwo. DARPA had previously awarded ALASA technology development contracts to Northrop Grumman, Space Information Laboratories and Ventions. 
In an interview with SpaceNews prior to the Boeing contract announcement, Brad Tousley, director of DARPA's Tactical Technology Office, said the agency was seeking to leverage existing production aircraft. "We're trying to get with an aircraft we don't have to modify or [modify] very, very little," he said.
ALASA program managers expect to perform propulsion and system risk reduction testing this year as well as complete captive-carry and aircraft compatibility flight tests, according to DARPA budget documents. The program is aiming for a demonstration launch in fiscal year 2015. 
"ALASA will enable small satellites to be deployed to orbit from an airborne platform, allowing performance improvement, reducing range costs and flying more frequently, which drives cost per event down," DARPA budget documents say. "The ability to relocate and launch from any major runway around the globe reduces the time needed to deploy a satellite system."
DARPA requested $55 million for the program in 2015, up from $42 million in 2014, according to the budget documents.
The Army and the Air Force have been identified as potential transition customers for the ALASA system, budget documents said.

Можно создать РН для вывода ПН массой 2-3 кг? Сколько такой пуск будет стоить?

[Александр Ч.]

Можно, 20 млн.$.
Столько же сколько и РН с ПН в тонну.

Потому что НИР и НИОКР.

И Что? НИР и НИОКР можно уменьшить, все уже изучено. Соотношение массы и ПН сохраняется, следовательно при экономии масштаба нано РН должен быть на порядок дешевле

Поймите, что олигархии не нужна никакая наука. Она не даёт прироста к комфорту.

А при чем тут олигархи? Мы же не науку обсуждаем а практический интерес. Мне кажется данный аспект как таковой к академической науке вообще имеет далекое отношение. Я например просто хочу понять цену такого вопроса, стоимость и время изготовления. ИМХО, в любом случае нано РН должен стоить во всех отношениях на много меньше чем нынешние сверхлегкие РН выводящие по 100-150 ПН
