ЦитироватьScience and Power Module, NEM

The Science and Power Module, NEM, (industrial designation 371KK63) should become the most advanced component joining the Russian segment of the International Space Station. As its name implies, it will carry state-of-the-art laboratory facilities and large power-generating solar arrays. NEM will also will also provide additional living quarters and new flight control systems. The module could also serve as a cornerstone of a future Russian space station and a deep-space outpost.

Origin of the NEM project

From the outset of the ISS project in 1993, the Russian segment of the orbital outpost was expected to include a specialized module combining functions of a space laboratory and a power-supply station. However the original version of the vehicle, known as Science and Power Platform, NEP, stalled on the ground around 2001 due to lack of funds. As a result, Russia had to barter electricity for its segment from NASA. However by the middle of 2000s, RKK Energia jump-started an effort to make the Russian segment independent from any external power supply.
It was decided to transfer most functions of the cancelled NEP platform to a pair of NEM modules, which would be attached to side ports of the yet-to-be-launched Node Module, UM. The newly developed NEM module provided much larger habitation volume than that available inside the cancelled NEP platform.
Both NEM spacecraft were to carry large solar panels with a total area of 155 square meters. The solar panels would be attached to their host spacecraft via a special rotating mechanism provided by ISS Reshetnev, the nation's prime manufacturer of communications satellites. ISS Reshetnev also took responsibility for the antenna system of the NEM module.
The module's power-supply system was expected to produce 18 kilowatt of electricity at the beginning of its life in orbit. Up to 12 kilowatt of this power could be channeled to the rest of the Russian segment at the station.
Last but not least, the NEM module would be equipped with a new-generation antenna enabling 24-hour communications with Russian ground stations via Luch-5 satellites. As a result, the Russian segment would no longer be dependent on the American satellite network.
New architecture

NEM modules were expected to feature an entirely new design, finally ending the reliance on the architecture of Vladimir Chelomei's TKS spacecraft, which had served as the basis for almost all Soviet and Russian space station modules exceeding 10 tons in mass. From the early days of the Mir space station, its developers complained that TKS-based modules were too bulky for the role. Still, after several incarnations, which considered one and two-launch scenarios, RKK Energia settled on a module large enough to require a Proton rocket, capable of delivering around 20 tons into the low Earth orbit.
Inside the module, engineers planned the installation of standard payload racks which would enable easy replacement of service systems and scientific instruments. Such a modular design echoed the architecture adopted for US modules on the ISS and for the European Columbus laboratory.
The module would also carry its own life-support systems and could feature a sleeping compartment, giving it a property of a fully independent space station. Thanks to its modular architecture, sleeping quarters and scientific payloads would be interchangeable.

Going to Lagrange and other missions

In addition to expanding the ISS, Russian developers viewed the NEM module as the basis for future Russian efforts to send humans beyond the Earth orbit. Thanks to its multi-function design, life support and power-supply capability, one or a whole cluster of such vehicles could provide habitation quarters and laboratories for a station at the so-called Lagrange points, which were considered as a staging ground for the exploration of the Moon, asteroids and Mars.
In case of an international agreement on the construction of a manned outpost in the Lagrange point, the NEM-based laboratory could constitute the Russian contribution into the effort. The NEM-based outpost could be serviced and staffed by the crews of US-European Orion spacecraft and by Russia's next-generation spacecraft, PTK NP.
Simularly, the NEM module, possibly in combination with other hardware, could serve as an outpost in the orbit around the Moon.
Also in 2014, plans were hatched to make the NEM-based laboratory a part of the post-ISS Russian space station, VShOS, in the high-inclination orbit.
Development
In the spring of 2012, Russian space agency, Roskosmos, ordered a fleet of four Proton-M rockets, one of which was reserved for the launch of the NEM-1 module. According to the tender documentation, the rocket would have to be manufactured by November 25, 2014.
In October 2012, the agency also announced a tender for the 15.15-billion ruble contract covering the development of the NEM-1 module itself until the end of November 2015. Not surprisingly, on October 30, Roskosmos awarded this work to RKK Energia, despite a lower bid from Moscow-based GKNPTs Khrunichev, the manufacturer of the Proton rocket and TKS-class modules. However, at the time, Roskosmos, funded the development of only one NEM module. If a single NEM was attached to the Russian segment at the originally planned location, it would cause an asymmetry in the layout of the outpost, thus complicating the attitude control of the station and increasing propellant expenditure.
Also, due to its unique architecture, the NEM module could not use any of standard payload fairings protecting the cargo of Proton rockets during the initial ride through the atmosphere. To resolve the problem, from 2012 to 2014, Zhukovsky Central Aero–Hydrodynamics Institute, TsAGI, was conducting wind-tunnel testing of a custom-designed payload section for the Proton, which could accommodate the NEM module.
As of the beginning of 2014, RKK Energia was yet to resolve another critical issue of manufacturing NEM modules. In a very unusual move for the Russian rocket industry, the company announced that it would consider bids from both domestic and foreign spacecraft developers. However, during the Farnborough air show in July, the head of RKK Energia Vitaly Lopota told the Interfax news agency that according to an already approved agreement, the NEM module would be manufactured at RKTs Progress, the developer of the Soyuz family of rockets. According to Lopota, the module would be completed by the end of 2016. Also in 2013, some unidentified responsibility for the module was expected to be subcontracted to the KBKhA (KB Khimmash) rocket propulsion center in Voronezh.

NEM appears in metal in 2016

In the first half of 2016, ZAO Orbita, based in the city of Voronezh, announced that it had received a contract from RKK Energia for the development of the power distribution and control system, ARK, of the NEM module. According to the agreement, the work had to be completed by 2018.
Also, during 2016, RKK Energia conducted a number of ergonomic studies in the mockup of the module's interior, including a trial installation of the Chibis-M life-support equipment and of a panel of the control console, as well as an assessment of the coloring scheme for the module's interior.
On Oct. 27, 2016, RKK Energia announced that the pressurized compartment of the NEM module intended for static testing had been delivered from RKTs Progress in Samara to the company's facility in Korolev. The module was later to be integrated with a prototype of the unpressurized section of the NEM module and transferred to the TsNIIMash research institute for testing scheduled at the beginning of 2017, RKK Energia said.
The prototype of the NEM module for static testing was indeed shipped to TsNIIMash on Dec. 28, 2016, marking a major milestone in the project.

Launch dates

When the concept of the NEM-1 and NEM-2 modules first appeared in the Russian forward-looking documents, their launches were projected in 2014 and 2015, respectively, however by the start of the actual development in 2012, the launch of NEM-1 was expected no earlier than 2016. In 2013, the launch slipped to 2017.
The Russian version of the ISS schedule revealed at the beginning of 2014 indicated the launch of a single NEM module at the end of 2017. However by April 2014, the launch of NEM was not expected before the end of 2018. In the first half of 2015, the NEM mission slipped to 2019.
A station's flight manifest surfaced in April 2015 indicated the launch of the NEM module in the middle of the fourth quarter of 2019.

 
NEM module to house Kosmorobot
On Nov. 11, 2016, RKK Energia announced that it had won a contract for the development of a mobile robotic system or Kosmorobot, which would take residence on the NEM module during the period from 2020 to 2024. Equipped with multiple robotic arms, the Kosmorobot will be able to crawl along the external railings of the NEM module, carrying cargo and conducting various activities, including installing and removing equipment, connecting electric cables and inspecting the module's surface. It is also expected to be able to cut through the soft thermal layers of the modules, provide lighting, screw and unscrew connectors and take samples from the surface.
Kosmorobot will be comprised of a base module, a power battery pack, two robotic arms, an attachment fixture, TV cameras and a transmitter/receiver. The interchangeable instrument kit will include a sampling set, screwdriver, scissors, a set for electric connection, a universal grapple and a specialized grapple for external railings. Robotic arms will have seven movement axis and carry their own technical vision cameras.
Developed in cooperation with TsNII RTK and NPO Androidnaya Tekhnika, Kosmorobot will be able to assist spacewalking cosmonauts, RKK Energia said.

Однако ж на мой взгляд возможность дальнейших стыковок к модулям куда важнее чем возможность двухстепенного наведения солнечных батарей. 
 То есть по оси НЭМ должен быть сквозной проход со стыковочным узлом на другом конце, обеспечивающий стыковку к этому модулю кораблей и других модулей. 
 То есть модули должны иметь конструкцию по типу 77-х  модулей. А установка на конце модуля солнечных батарей не имеет разумных объяснений кроме обезьянничания: "У американцев двухстепенной привод, значит и нам нада!"
 В дальнейшем когда потребуется наращивать станцию будут кусать локти что когдато залепили стыковочный узел солнечной батареей. 
 И вобще занятие половины длины модуля неизвестно чем - странное решение. Гиродины и аккумуляторы снаружи это зачем? Чтоб потом тратить ресурс рабочего времени и скафандров на выходы в открытый космос для замены всего этого? Или чтоб как на Мире - распилить душевую кабинку чтоб поставить гиродины туда? Увы, история нас ничему не учит. :(

Вобщем вспомните мои слова - решение вместо второго стыковочного узла прилепить привод солнечных батарей глубоко ошибочное и авторы этого решения очень скоро об этом пожалеют.

Хорошая схемка. Одно непонятно: в научно-энергетическом модуле для науки так ни одной секции и нет. 
Я понимаю что в действительности модуль служебный и наука там и рядом не стояла, но зачем тогда его обзывать научным?

Кто мне скажет своё мнение: эволюция от модулей типа 77КС к модулям типа НЭМ это прогресс или деградация?

С идеологической точки зрения один стыковочный узел, безусловно, деградация.

Дем

Совмещение в одном модуле жилого гермообъёма и энергетики безусловно деградация.
Энергетический модуль должен быть вообще без стыковочного узла, одно гнездо для розетки :)
Летать в космос необходимо. Жить - не необходимо.

ЦитироватьScience and Power Module to wait until 2021

During 2017, a full-scale prototype of Russia's new-generation space station module, NEM-1, began a series of extensive tests which would clear its flight-worthy successor for launch and a multi-year mission in orbit. However the project faced a likely launch delay until at least 2021, or almost two years behind the latest schedule, because of delays in funding, sources at RKK Energia said.
 
Previous chapter: NEM-1 module home page
Architecture of the NEM module as of 2016.
Work in progress
In January 2017, the prototype of the NEM-1's pressurized compartment, designated 372P321.0000X51-0, arrived at the TsNIIMash research institute in Korolev near Moscow for static and endurance tests. By the beginning of September, engineers has completed 19 out of 27 static testing modes planned for the module. The full completion of static testing was expected in October. During the same month, the endurance tests on the NEM prototype were expected to begin.
Following the pressurized compartment, a prototype of the unpressurized section of the NEM-1 module arrived at TsNIIMash in August for similar tests. The entire test program with this segment of the spacecraft was to be completed in January 2018.
In the meantime, on July 31, 2017, the flight version of the pressurized module known as 372P321.1100-0 arrived at RKK Energia from the manufacturing plant at RKTs Progress in Samara in Southern Russia. As of September, RKK Energia was conducting an acceptance review of the structure. Around the same time, RKK Energia was expecting the delivery from RKTs Progress of another full-scale prototype designated 372P321.1100X61-0 intended for vibration and strength tests.
Financial problems
Although the development work on the NEM-1 progressed well, there were looming delays in the project caused by lack of funding. As a result, RKK Energia was unable to pay its subcontractors to complete the necessary work on various components of the spacecraft. Key areas of concern for management were the propulsion system, the driving mechanism for the solar panels, the solar panels themselves, the telemetry system and power batteries.
In the second half of 2017, project officials estimated that upon making up the funding shortfall, the NEM-1 module could be realistically ready for launch to the ISS in 2021 or around two years after the 2019 launch date which appeared in the most recent publicly available schedules for the assembly of the Russian ISS segment.

Космонавтика и все что рядом
"Научно-энергетический модуль уехал на 2021 год (с 2019) из-за проблем с финансированием. Не то чтобы это было неожиданно (перенос хотя бы на год стал неизбежен из-за задержек с МЛМ-У), но все-таки."
