МОСКВА, 24 мая - РИА Новости. Российский двигатель РД-181 производства НПО "Энергомаш" (входит в госкорпорацию "Роскосмос[I]"[/I]) благодаря изменению режима своей работы позволит увеличить на тонну грузоподъемность американской ракеты-носителя Antares, сообщил РИА Новости в пятницу источник в ракетно-космической отрасли.

"Уже со следующего пуска, планирующегося на 19 октября с грузовым кораблем Cygnus, ракета Antares сможет выводить на тонну больше полезной нагрузки, чем раньше", - сказал собеседник агентства.

По его словам, это станет возможным за счет изменения режима работы двигателя РД-181, установленного на первой ступени ракеты Antares. "Раньше двигатель при полете ракеты сквозь зону максимального скоростного напора уменьшал свою тягу до 55% от номинальной. Теперь же после упрочнения конструкции ракеты тягу двигателя не надо будет уменьшать, что позволит увеличить ее грузоподъемность на тонну", - пояснил источник.

В "Роскосмосе" не стали комментировать РИА Новости эту информацию.

[QUOTE][SIZE=6]ATLAS V DEPARTS FACTORY FOR HISTORIC MISSION[/SIZE]

[B]May 23, 2019 --[/B] The first Atlas V rocket to launch astronauts into space emerged from the United Launch Alliance factory today, rolling into a giant cargo ship for transport to Cape Canaveral.

[IMG]http://www.ulalaunch.com/images/default-source/gallery/av_082_roll-6.jpg?sfvrsn=e3d9567c_0[/IMG]

ULA built the Atlas V at the sprawling 1.6-million-square-foot manufacturing facility in Decatur, Alabama, taking raw materials and turning them into a rocket to launch the first crew of Boeing's CST-100 Starliner spacecraft.

After speeches celebrating the milestone by Alabama elected officials and ULA and Boeing dignitaries in attendance, ULA workers moved the Atlas V booster stage and Centaur upper stage down the road for loading into the Mariner vessel docked nearby.

The 312-foot-long ship is purpose-built to navigate both shallow waters of rivers and ocean travel to reach ULA's launch sites. It has been making the trek from Decatur to Cape Canaveral since 2001.

CFT will follow the maiden voyage of Starliner, the uncrewed Orbital Flight Test (OFT) targeted for August.

Aboard will be Boeing astronaut Chris Ferguson, a three-time space shuttle astronaut and commander of space shuttle Atlantis on the final shuttle mission; NASA astronaut Mike Fincke, a veteran of three spaceflights, including two long-duration stays on the International Space Station, and NASA astronaut Nicole Mann, a spaceflight rookie making her first trip into space.

Once at Cape Canaveral Air Force Station in Florida, the Atlas V will begin integrated operations and processing for the CFT launch.

[B]Вашингтон. 24 мая. ИНТЕРФАКС -[/B] Тяжелая американская ракета-носитель Falcon 9 в пятницу утром по московскому времени должна с третьей попытки вывести на орбиту 60 мини-спутников, предназначенных для начала создания глобальной сети интернет-покрытия в рамках проекта Starlink, сообщила компания-разработчик SpaceX.

Запуск ракеты должен состояться в промежутке времени между 05:30 и 07:00 мск с 40-го стартового комплекса на космодроме NASA на мысе Канаверал в штате Флорида.

[SIZE=6][B]В NASA заявили, что США сделали первый шаг в реализации лунной программы "Артемида"[/B][/SIZE]

[SIZE=3]В ведомстве сообщили, что создание энергетического модуля и электродинамического двигателя, питающегося от солнечных батарей, позволит начать строительство окололунной станции Gateway[/SIZE]

[B]НЬЮ-ЙОРК, 23 мая. /ТАСС/[/B]. Создание энергетического модуля и электродинамического двигателя для окололунной станции Gateway станет первым шагом в реализации американской программы исследований Луны, получившей название Artemis ("Артемида[I]"[/I]). Об этом сообщил в четверг на пресс-конференции в Вашингтоне заместитель главы Национального управления США по аэронавтике и исследованию космического пространства (NASA) Уильям Герстенмайер. Трансляция его выступления шла на сайте NASA.

"Мы фактически приступили к реализации директивы по космической политике, изданной президентом Дональдом Трампом, - отметил он. - Мы сделали первый шаг в реализации программы Artemis по исследованиям Луны. Создание энергетического модуля и электродинамического двигателя, питающегося от солнечных батарей, позволит нам начать строительство окололунной станции Gateway, которая со временем даст возможность доступа к любой точке на поверхности Луны".

Как отмечалось на пресс-конференции, масса первого модуля составит около 5 тыс. кг, а мощность электродинамического двигателя, питающегося от солнечных батарей - около 50 кВт. За счет этой двигательной установки Gateway, срок эксплуатации которого определен в 15 лет, сможет осуществлять коррекцию орбиты. На первом модуле, как ожидается, будет установлен также дистанционный манипулятор и стыковочный узел. Размеры модуля для Gateway позволяют использовать для его доставки на орбиту - предположительно в конце 2022 года - различные типы ракет-носитетелей.

Ранее NASA объявило о том, что новая программа высадки астронавтов на Луну будет называться "Артемида".[/QUOTE]

AA-2 will demonstrate the abort system can activate, steer the spacecraft, and carry astronauts to a safe distance if an emergency arises during Orion’s climb to orbit as the spacecraft faces the greatest aerodynamic pressure during ascent. AA-2 is an important test to verify Orion’s design to safely carry astronauts on deep space missions as NASA works to land the first woman and next man on the [url=https://www.nasa.gov/feature/sending-american-astronauts-to-moon-in-2024-nasa-accepts-challenge]Moon by 2024[/url].

During the three-minute [url=https://youtu.be/6HK9G7feXEk]test[/url], the LAS with the Orion test article will launch atop a booster from Space Launch Complex 46 at Cape Canaveral Air Force Station, to an altitude of about six miles and traveling at more than 1,000 mph. The abort motor will quickly whisk the crew module away from the booster, and the attitude control motor will maneuver the assembly into position to jettison the crew module. Test data from 890 [url=https://www.nasa.gov/centers/armstrong/AFRC_contributes_AA-2.html]sensors[/url] will be sent in real-time to ground sites as well as recorded on board by 12 data recorders. The 12 data recorders will eject from the crew module before Orion reaches the water and will be [url=https://www.nasa.gov/feature/successful-test-proves-important-step-toward-safeguarding-astronauts]retrieved[/url] after the test.

With no astronauts on board, the test concludes after the data recorders are ejected and does not include parachutes or recovery of the test capsule. AA-2 is focused on testing Orion’s ability to abort during ascent, and NASA has already fully qualified the parachute system for flights with crew through an extensive series of 17 developmental tests and 8 qualification tests [url=https://www.nasa.gov/feature/nasa-completes-orion-parachute-tests-for-missions-with-astronauts]completed[/url] at the end of 2018.

In one of the first steps of the agency’s Artemis lunar exploration plans, NASA announced on Thursday the selection of Maxar Technologies, formerly SSL, in Westminster, Colorado, to develop and demonstrate power, propulsion and communications capabilities for NASA’s lunar [url=https://www.nasa.gov/topics/moon-to-mars/lunar-outpost]Gateway[/url].

“The power and propulsion element is the foundation of Gateway and a fine example of how partnerships with U.S. companies can help expedite NASA’s return to the Moon with the first woman and next man by 2024,” said NASA Administrator Jim Bridenstine. “It will be the key component upon which we will build our lunar Gateway outpost, the cornerstone of NASA’s sustainable and reusable Artemis exploration architecture on and around the Moon.”

The power and propulsion element is a high-power, 50-kilowatt [url=https://www.nasa.gov/mission_pages/tdm/sep/index.html]solar electric propulsion[/url] spacecraft – three times more powerful than current capabilities. As a mobile command and service module, the Gateway provides a communications relay for human and robotic expeditions to the lunar surface, starting at the Moon’s South Pole.

This firm-fixed price award includes an indefinite-delivery/indefinite-quantity portion and carries a maximum total value of $375 million. The contract begins with a 12-month base period of performance and is followed by a 26-month option, a 14-month option and two 12-month options.

Spacecraft design will be completed during the base period, after which the exercise of options will provide for the development, launch, and in-space flight demonstration. The flight demonstration will last as long as one year, during which the spacecraft will be fully owned and operated by Maxar. Following a successful demonstration, NASA will have the option to acquire the spacecraft for use as the first element of the Gateway. NASA is targeting launch of the power and propulsion element on a commercial rocket in late 2022.

“We’re excited to demonstrate our newest technology on the power and propulsion element. Solar electric propulsion is extremely efficient, making it perfect for the Gateway,” said Mike Barrett, power and propulsion element project manager at NASA’s Glenn Research Center in Cleveland. “This system requires much less propellant than traditional chemical systems, which will allow the Gateway to move more mass around the Moon, like a [url=https://www.nasa.gov/nextstep/humanlander2]human landing system[/url] and [url=https://www.nasa.gov/feature/nasa-begins-testing-habitation-prototypes]large modules[/url] for living and working in orbit.”

Charged with returning to the Moon within five years, NASA’s [url=https://www.nasa.gov/feature/sending-american-astronauts-to-moon-in-2024-nasa-accepts-challenge]lunar exploration plans[/url] are based on a two-phase approach: the first is focused on speed – landing on the Moon by 2024 – while the second will establish a sustained human presence on and around the Moon by 2028. We then will use what we learn on the Moon to prepare to send astronauts to Mars.

Indian engineers hope to launch the country’s first robotic lunar lander between July 9 and July 16 on India’s most powerful rocket, the head of the Indian space agency said this week.

The robotic Chandrayaan 2 mission will launch on the heaviest rocket in India’s inventory, the Geosynchronous Satellite Launch Vehicle Mk.3, fr om the country’s spaceport on Sriharikota Island, located on the coast with the Bay of Bengal around 50 miles (80 kilometers) north Chennai.

The mission’s week-long launch period opens July 9, according to K. Sivan, chairman of the Indian Space Research Organization. Chandrayaan 2 is the next mission on India’s launch calendar after Wednesday’s liftoff of a Polar Satellite Launch Vehicle carrying the RISAT 2B radar observation satellite.

“The next mission is the most complex mission ISRO has ever undertaken, that is the Chandrayaan 2 mission,” Sivan said in remarks after Wednesday’s launch of RISAT 2B. “It is not only a launch mission. We are going to land precisely at a place wh ere nobody’s ever gone. This is challenging for the whole ISRO team. I don’t have any doubt that team ISRO will achieve the target of this mission, with the precision of what we’re aiming for.”

The launch of Chandrayaan 2 would come just shy of the 50th anniversary of the Apollo 11 and landing.

Chandrayaan 2 consists of three segments, an orbiter module to guide the spacecraft to the moon, a descent stage to land on the lunar surface, and a rover to scout the landing site in the southern lunar highlands.

If the launch occurs in the July window, Chandrayaan 2’s landing is scheduled for Sept. 6, Sivan said.

The mission will be India’s first attempt at a lunar landing, seeking to become the fourth country to accomplish a soft landing on the moon after the former Soviet Union, the United States and China.

India launched its first lunar orbiter, named Chandrayaan 1, in 2008. One of Chandrayaan 1’s major accomplishments was the discovery of water-bearing molecules at the moon’s poles, with the highest concentrations inside permanently-shadowed craters at the south pole.

Chandrayaan 2 will aim for touchdown in an unexplored region of the moon, targeting a landing closer to the lunar south pole than any previous mission.

The expected landing site is located at approximately 71 degrees south latitude, roughly 220 miles (350 kilometers) from the rim of the South Pole-Aitken basin, a region scientists believe is one of the most ancient impact sites in the solar system, created when a large asteroid or comet struck the moon billions of years ago.

For the first time, Chandrayaan 2’s rover could examine ancient material in the lunar crust ejected during the colossal collision that created the South Pole-Aitken basin, providing data that could yield clues about the solar system’s chaotic early history. The rover, named Pragyan, carries an alpha particle X-ray spectrometer to measure the elemental composition of the rocks at the Chandrayaan 2 landing site, along with a laser-induced breakdown spectroscope.

China accomplished the first soft landing on the far side of the moon in January in the mid-latitudes of the southern hemisphere, within the South Pole-Aitken basin. The Chang’e 4 mission’s stationary lander and rover are still operational.

But Chang’e 4 did not carry an X-ray spectrometer to obtain elemental measurements of the lunar crust. The presence of such an instrument on-board Chandrayaan 2 could be boon for lunar geologists.

Five science payloads will each operate on the Chandrayaan 2 lander, dubbed Vikram, and the mission’s orbiter component. The instruments include spectrometers, radars, plasma sensors and cameras.

The Chandrayaan 2 landing craft also carries a passive laser retro-reflector provided by NASA to allow precise measurements between the Earth and the moon, and potentially become a node in a lunar navigation network to help guide future missions.

Chandrayaan 2 will launch on the first operational flight of the GSLV Mk.3, India’s most powerful rocket. The GSLV Mk.3 is powered by two side-mounted solid rocket boosters, among the biggest solid-fueled rockets in the world, generating 2.2 million pounds of thrust at liftoff.

An air-lit core stage with two hydrazine-fueled Vikas engines and an upper stage with a hydrogen-fueled engine will send the Chandrayaan 2 mission into space.

Indian space program managers last year moved the Chandrayaan 2 launch from the less capable GSLV Mk.2 rocket to the GSLV Mk.3 to accommodate mass growth on the lunar mission.

Chandrayaan 2 now has a combined launch mass of more than 3.8 metric tons, or about 8,500 pounds. The mission reportedly costs around $125 million.[/QUOTE]
