Ничего не понял, но очень интересно!

Что же входит в увеличенную цену запуска? Официально NASA заявляет о следующем:

— Инфраструктура для подготовки полезной нагрузки
— Работа подрядчиков
— Подготовка к запуску на космодроме
— Топливо для модулей
— Обеспечение связью и телеметрией.
НАСА такое не заявляло, а часть этого заявляли некоторые популизаторы

А может кто-либо рассказать, что это за орбита какая, "sub GTO"? 
Ещё бывает, оказывается, и "Super GTO". Это тоже непонятно...

ЦитироватьNASA заявляет, что не может публиковать информацию о том, предлагала ли SpaceX спасти ускорители Falcon Heavy при запуске модулей Gateway. "Это чувствительная информация для конкуренции", - заявило агентство.

Как модули будут добираться к Луне❓

Представитель NASA сообщил, что Falcon Heavy запустит модули PPE и HALO на орбиту Земли, а PPE отправит их на орбиту Луны. Параметры парковочной орбиты пока находятся на рассмотрении, возможности Falcon Heavy зависят от того, будут ли её ускорители спасены или израсходованы в этом запуске.

Вторичной много не наберет, так как в радиационных поясах заряженные частицы, они вторичное излучение не вызывают.

просто, т.к. тут мелькали недавно цифры которые вообще-то далеки от затрат на модули

Цитата: Sam  Grey от 10.02.2021 19:44:27Контракты на производство самих модулей давно выданы совсем другим людям. Например, контакт на PPE был выдан Maxar ещё в 2019, общая стоимость $375 миллионов.

Сборка модуля HALO началась. Thales Alenia Space в сотрудничестве с генеральным подрядчиком Northrop Grumman открывает новую веху в освоении Луны.
На кадрах ниже, сварка двух компонентов, кольца и цилиндра для HALO, это можно считать началом сборки основной конструкции модуля. Сам HALO основан на компоновке кораблей Cygnus, которые снабжают МКС уже долгое время.
Также Thales Alenia Space была выбрана ЕКА в качестве генерального подрядчика для 2 модулей, I-HAB и ESPRIT, предназначенных для Gateway. И наконец, компания Axiom Space выбрала Alenia в качестве поставщика 2 модулей своей будущей коммерческой космической станции.

We're Fired Up! Gateway's Propulsion System Passes First Test

The thruster system that will propel NASA's Gateway around the Moon was recently fired up for the first of many ground tests to ensure the Power and Propulsion Element (PPE) is ready for flight.

NASA, along with Maxar Technologies and Busek Co., successfully completed a test of the 6-kilowatt (kW) solar electric propulsion (SEP) subsystem destined for the PPE. The hot fire tests were funded by NASA's Space Technology Mission Directorate, which helps foster the development of commercial space capabilities, and included multiple start-ups and shutdowns and other flight-like scenarios to demonstrate the system is ready for the transit to the Moon and extended operations there.

"This is an exciting first step toward proving the PPE's propulsion system will meet Gateway's requirements," said Mike Barrett, Power and Propulsion Element manager at NASA's Glenn Research Center. "These thrusters will be critical in delivering the first elements of Gateway to lunar orbit and will help us create a dynamic exploration platform over Gateway's 15-year lifespan."

This SEP thruster is about 30% more powerful than anything Maxar or Busek have previously flown. Several of these 6-kilowatt thrusters will later be combined with other, higher-power thrusters to complete the PPE's 50kW electric propulsion system. In total, the PPE will be the most powerful electric propulsion spacecraft ever flown and it will maneuver Gateway around the Moon, opening up more of the lunar surface for exploration than ever before.

RELEASE 21-092
NASA, Northrop Grumman Finalize Moon Outpost Living Quarters Contract

NASA and Northrop Grumman of Dulles, Virginia, have finalized a contract to develop the Habitation and Logistics Outpost (HALO) for Gateway, which will be a critical way station and outpost in orbit around the Moon as part of NASA's Artemis program.

NASA and its commercial and international partners are building Gateway to support science investigations and enable surface landings at the Moon, which will help prepare astronauts for future missions to Mars.

The firm, fixed-price contract is valued at $935 million. Under the contract, Northrop Grumman will be responsible for attaching and testing the integrated HALO with the Power and Propulsion Element (PPE), being built by Maxar Technologies. Northrop Grumman will also lead the integrated PPE and HALO spacecraft turnover and launch preparation with SpaceX, and support activation and checkout of HALO during the flight to lunar orbit. NASA is targeting November 2024 to launch the integrated spacecraft on a SpaceX Falcon Heavy rocket.

"NASA is building the infrastructure to expand human exploration further out into the solar system than ever before, including Gateway, the lunar space station that will help us make inspirational scientific discoveries at and around the Moon. Just as importantly, these investments will help NASA carry out the United States' horizon goal: to further develop and test the technology and science needed for a human trip to Mars," said NASA Administrator Bill Nelson. "The HALO is a critical component of Gateway, and this exciting announcement today brings us one step closer to landing American boots on both the Moon and Mars."

HALO is where astronauts will live and conduct research while visiting the Gateway. The pressurized living quarters will provide command and control systems for the lunar outpost, and docking ports for visiting spacecraft, such as NASA's Orion spacecraft, lunar landers, and logistics resupply craft. The HALO module will serve as the backbone for command and control and power distribution across Gateway and will perform other core functions, including hosting science investigations via internal and external payload accommodations and communicating with lunar surface expeditions. HALO also will enable the aggregation of additional habitable elements to expand Gateway capabilities. Immediately after launch, the Heliophysics Environmental and Radiation Measurement Experiment Suite, built by NASA's Goddard Space Flight Center in Greenbelt, Maryland, will begin conducting research outside of the integrated spacecraft.

"This is a major step on the path for Artemis, not just for NASA, but for the combined team, including our commercial and international partners," said Kathy Lueders, NASA associate administrator for Human Explorations and Operations. "Gateway will provide unprecedented access to the Moon and symbolizes the expansion of our partnerships into deep space."

The integrated PPE and HALO will be the Gateway's foundation, enabling humanity's first permanent outpost in orbit around the Moon. Located tens of thousands of miles from the lunar surface at its farthest point and within easy range of lunar landers at its closest, the Gateway will be in a near-rectilinear halo orbit. This orbit will allow NASA and its international and commercial partners to conduct unprecedented deep space science and technology investigations, and conduct sustainable lunar exploration.

"This action puts in place the final contract component of a diverse, multi-faceted team –distributed across the country and within some international partner facilities – working together to create and implement the initial Gateway capability. We are excited to work with Northrop Grumman and all the partners to deliver the cornerstone of sustainable human exploration in cis-lunar space," said Dr. Jon Olansen, NASA's manager of the HALO project.

HALO leverages contributions from the Gateway international partners for robust capabilities. Batteries provided by the Japan Aerospace Exploration Agency (JAXA) will power HALO until PPE solar arrays can be deployed and during eclipse periods. Robotic interfaces provided by the Canadian Space Agency will host payloads and provide base points for Canadarm3 robotic operations. ESA (European Space Agency) will provide a lunar communications system to enable high-data-rate communications between the lunar surface and Gateway. With three docking ports, HALO will be the hub for international Gateway expansion in the future, including an international habitat that ESA and JAXA will provide, and an ESA-provided refueling module. The docking ports also will host a human landing system for lunar surface expeditions and logistics resupply spacecraft. As the Gateway hub, HALO will provide power, data, airflow to each of these ports, as well as thermal conditioning to assist future elements and spacecraft in controlling the temperature of their equipment and habitable environment.

"Leveraging our success with our Cygnus spacecraft, Northrop Grumman is perfectly positioned to deliver the HALO module, a critical piece for NASA's Artemis program and our journey to the Moon and beyond," said Frank DeMauro, vice president and general manager for tactical space systems at Northrop Grumman. "After recently completing a successful preliminary design review, we now look forward to completing the detailed design efforts and eventually bringing HALO to life in our Gilbert, Arizona, facility while also providing integration services for the final, combined vehicle before launch."

HALO's design is based on Northrop Grumman's Cygnus spacecraft, which has completed 15 resupply missions to the International Space Station to date. A previous contract for HALO, awarded in June 2020, funded work through preliminary design review, one of a series of checkpoints for the complex engineering project. The review process for the module, completed in May, assessed all of the spacecraft's design to ensure the overall system is safe and reliable for flight and meets NASA's mission requirements.
