CXNB-2  детектор гамма частиц?
Как я понимаю (30-50 МэВ) из
http://www.ufn.ru//ufn96/ufn96_2/Russian/r962c.pdf
понятно не много. Но все-таки это великий Гинзбург, поэтому суть спутника раскрыта в двух фразах:
 
"Начиная с 1972 г., удалось принимать на спутниках гамма-излучение (с энергией больше 30-50 МэВ), образующееся в результате распада  pi (0) - мезонов, генерируемых в космосе при столкновениях протонно-ядерной компоненты космических лучей с ядрами межзвездной среды."
 
"Распад pi(0)-мезонов (ср. время жизни составляет 0,84*10**(-16) с) с вероятностью 98,8% происходит по каналу pi(0)-мезон -> 2 гамма кванта. Поэтому при распаде покоящегося pi(0)-мезона образуется гамма-фотоны с энергией  ...67,5 МэВ."
Или как раз частицы с таким значением стараются не регистрировать?

Из названия сабжа следует, что заниматься он будет фоновым рентгеновским (X-ray) излучением, что подразумевает  исследуемую энергетику на порядки ниже, нежели у гамма-издучения, о чем в статье прямо говорится

The goal of the CXBN-2 mission is to increase the precision of measurements of the CXB in the 30 to 50 keV

Неуважаемая "тётя Вики" указывает диапазон энергий рентгеновского излучения от 100 эВ до 250 кэВ, т.о. сабж изучает излучение ближе скорее к нижней границе диапазона энергий, ни о каких мегаэлектрон-вольтах речи не идёт.

The seventh commercial resupply services mission for Orbital ATK, CRS-7, is targeted for liftoff atop a United Launch Alliance Atlas V rocket from Cape Canaveral Air Force Station in Florida March 19 at 10:56 p.m. EDT, which is at the opening of a 30-minute launch window.

Orbital ATK uses the Cygnus to perform space station resupply flights under the Commercial Resupply Services contract. Cygnus consists of a pressurized cargo module for crew supplies, scientific experiments and equipment, together with an associated service module providing solar power and propulsion. This mission will be the fourth flight of the extended variant of Orbital ATK's Cygnus pressurized cargo module, which increases the spacecraft's interior volume capacity by 25 percent, enabling more cargo to be delivered with each mission. The CRS-7 freighter will be delivering more than 7,500 pounds of cargo and science experiments to the station, including an advanced plant habitat system and other experiments to be conducted in the U.S. National Lab ranging from targeted cancer cell therapies to growing crystals. Cygnus will also carry dozens of small satellites including 28 from universities around the world in coordination with NanoRacks and the Von Karman Institute's QB50 CubeSats program.

Investigations scheduled on this launch include an Advanced Plant Habitat, which will integrate new technology to increase overall efficiency, reliability, and robustness of plants grown on station. This experiment will build on the success of NASA's Veggie, the first fresh food growth system on station, and will provide ongoing research for the development of food production systems for long-duration exploration missions.

Manipulating cell cultures in space is challenging as the cells can spontaneously grow in 3-D. Another new investigation bound for the U.S. National Laboratory will look at using magnetized cells and tools to make it easier to handle cells and cultures, and improve the reproducibility of experiments.
The Slosh Coating experiment will investigate a special type of coating that can repel liquids when applied to container walls. If effective, the liquid repellent could be used to design more efficient storage tanks for propellant and other fluids used in space exploration.

There also will be a number of CubeSats onboard Cygnus that will be deployed from the NanoRacks CubeSat Deployment on the space station, including a NASA science payload known as IceCube, which will provide data to scientists' understanding of ice clouds and their role in climate change....

Американский грузовой корабль Cygnus отправится на МКС 19 марта
ВАШИНГТОН, 6 мар – РИА Новости. Старт космического грузового корабля Cygnus компании Orbital ATK к Международной космической станции намечен на вечер 19 марта (раннее утро 20 марта по Москве), сообщает НАСА.
Как рассказала представитель ведомства на брифинге, запуск грузового корабля на ракете-носителе Atlas V компании United Launch Alliance (ULA) с космодрома на мысе Канаверал (Флорида) должен состояться в 22:56 по времени Восточного побережья США (5:56 мск 20 марта).
Ранее сообщалось, что запуск может состояться 16 марта.
Грузовик доставит на МКС провиант, предметы первой необходимости и материалы для научных экспериментов.
Как сообщалось ранее, решение, что грузовой корабль выведет на орбиту принадлежащая United Launch Alliance Atlas V, а не ракета Orbital ATK Antares, было принято в связи с большей грузоподъемностью Atlas V.
Ожидалось, что после успешного возвращения ракеты Antares к полетам, прерванным в связи с катастрофой 2014 года, старты к МКС будут осуществляться на ней с космодрома Валлопс в американской Виргинии. Полеты Orbital ATK на собственной ракете Antares, оснащенной российскими двигателями РД-181, как предполагается, возобновятся в середине 2017 года.

What is on the Cygnus Cargo Module?

The Cygnus Cargo Module will be packed with more than 7,500 pounds of cargo and supplies for the astronauts on the International Space Station. Along with the cargo and supplies, the module will carry 38 cubesats or micro-satellites by NanoRacks of Texas, new habitat to grow plants on the ISS and the Spacecraft Fire Experiment-III (SAFFIRE-III). 

Along with the SAFFIRE-III, the Cygnus will also carry the Reentry Data Collection (RED-Data-2) flight recorder to provide crucial data about the extreme conditions a spacecraft encounters during atmospheric reentry. The RED-Data-2 flight recorder was built by Terminal Velocity Aerospace.

Out of 38 cubesats, 28 will be used for the QB50 mission, which will study the lower thermosphere. Four of the cubesats will launch directly from the Cygnus during flight towards the ISS, while the remaining will be launched from the space station.

 
The Advanced Plant Habitat will be used to conduct plant bioscience research on the space station and to help NASA prepare crew to grow their own food while on deep-space exploration missions.

Lifting off from Space Launch Complex 41 on March 19 at 10:56 p.m. EDT, the rocket will place the spacecraft on a precise path to reach the space station about four days later. Cygnus, operated by the Orbital ATK mission team, will approach close enough for the station's 55-foot-long robotic arm to grapple the supply craft and connect it to one of the ports on the orbiting laboratory.
The spacecraft, powered by its own set of solar arrays, will remain connected to the station until June. During that time, astronauts will unload the Cygnus, including research dedicated to range of fields such as astronomy, biology, crystal growth and technology development. The spacecraft also will carry an advanced plant habitat for growing vegetables in orbit.  

"We have more than 2,000 pounds of scientific experiments on board spanning all fields of science onboard," said Holly Vavrin, a commercial visiting vehicle engineer in NASA's International Space Station Program Office. "There are also 38 CubeSats launching on this mission, including four that will launch from the Cygnus and 34 that will be launched from the station to conduct a range of experiments including testing long-life battery systems, study cloud systems and measure background radiation."

Later, astronauts will pack it with trash, unneeded equipment and spent experiments. After detaching from the station, a final experiment will be conducted to test how fire burns in space before Cygnus plunges into the atmosphere and burns up over the Pacific Ocean.
