Что б она померла либо кто-то очень 'талантливый' должен родиться, либо она должна всех 'достать' (проблемами, стоимостью, потерей интереса к пилотируемым полетам). Но она сама ещё не родилась да и альтернативы пока нет.

Это смотря что понимать под российским супертяжем. Поскольку проект SLS уже утвержден, а наш со всеми деталями - еще нет.

Кстати, джентльмены, вы заметили, что в последнее время Голливуд стал чаще выпускать фильмы о полётах на Луну, МКС и Марс?
Это хороший признак - пытаются заинтересовать налогоплательщиков пилотируемой космонавтикой.

The mobile launcher for NASA's Artemis missions rolls out of the Vehicle Assembly Building (VAB) at Kennedy Space Center in Florida on Sept. 10, 2019, after spending a week and a half inside due to the approach of Hurricane Dorian. The nearly 400-foot-tall structure was moved fr om Launch Pad 39B to the VAB for safekeeping on Aug. 30. The storm passed about 70 miles east of the spaceport during the overnight hours Tuesday, Sept. 3, and Wednesday, Sept. 4.

NASA's Exploration Ground Systems is moving the mobile launcher back to the launch pad, wh ere teams will complete testing and checkout on the launcher in the coming weeks for the Artemis I mission.

NASA eclipsed another milestone in its plan to send the first woman and next man to the lunar surface by 2024 with the latest successful water flow test on the mobile launcher at Kennedy Space Center's Pad 39B.

Using adjustments from the first water flow test event in July, the Friday, Sept. 13 exercise demonstrated the capability of the sound suppression system that will be used for launch of NASA's Space Launch System (SLS) for the Artemis I mission.

During the 30-second test, about 450,000 gallons of water poured onto the Pad B flame deflector, the mobile launcher flame hole and onto the launcher's blast deck. The system reached a peak flow rate of more than 1 million gallons per minute. While the visual is dramatic, the water's main purpose come launch day involves sound.

"SLS will create about 176 decibels at liftoff, which is significantly louder than a jetliner," said Launchpad Element Deputy Project Manager Nick Moss. "The sheets of water created by the flow will curb that sound by knocking it down a few decibels."


When the rocket's engines ramp up to full power, the hot exhaust starts to push harder in the confined space of the mobile launcher. These pressure waves can cause vibrations that could potentially damage the mobile launcher, as well as the rocket about to take flight.

"The sound suppression system acts as a dampener, absorbing the acoustic energy and reducing the strength of the pressure waves," said Cliff Lanham, mobile launcher senior project manager. "It creates a protective environment to ensure safe liftoff."

The sound suppression system starts flowing about 20 seconds before T-Zero. Smoke and fire from the vehicle starts about 10 seconds later.

"And that's what we're all here for — making sure that we can get to those last 10 seconds safely and get the vehicle going," Moss said.

Friday's test was the first time the ground launch sequencer software that will be used on launch day was used to command launch support systems at Pad B from the Launch Control Center. The weekend tests included a nominal launch countdown flow and a single valve failure test flow to better characterize off-nominal system performance.

The team is currently performing post-test analysis on these events in preparation for a final water flow test in the coming weeks, involving the hydrogen burn-off igniters.

NASA Joins Last of Five Sections for Space Launch System Rocket Stage


NASA finished assembling the main structural components for the Space Launch System (SLS) rocket core stage on Sept. 19. Engineers at NASA's Michoud Assembly Facility in New Orleans fully integrated the last piece of the 212-foot-tall core stage by adding the engine section to the rest of the previously assembled structure. Boeing technicians bolted the engine section to the stage's liquid hydrogen propellant tank. The engine section is located at the bottom of the 212-foot-tall core stage and is one of the most complicated pieces of hardware for the SLS rocket. It is the attachment point for the four RS-25 rockets and the two solid rocket boosters that produce a combined 8.8 millions pounds of thrust to send Artemis I to space. In addition, the engine section includes vital systems for mounting, controlling and delivering fuel fr om the stage's two liquid propellant tanks to the rocket's engines. This fall, NASA will work with core stage lead contractor, Boeing, and the RS-25 engine lead contractor, Aerojet Rocketdyne, to attach the four RS-25 engines and connect them to the main propulsion systems inside the engine section.

NASA finished assembling and joining the main structural components for the largest rocket stage the agency has built since the Saturn V that sent Apollo astronauts to the Moon. Engineers at the agency's Michoud Assembly Facility in New Orleans connected the last of the five sections of the Space Launch System (SLS) rocket core stage on Sept. 19. The stage will produce 2 million pounds of thrust to send Artemis I, the first flight of SLS and NASA's Orion spacecraft to the Moon.

"NASA has achieved a historic first milestone by completing the final join of the core stage structure for NASA's Space Launch System, the world's most powerful rocket," said Julie Bassler, the NASA SLS stages manager. "Now, to complete the stage, NASA will add the four RS-25 engines and complete the final integrated avionics and propulsion functional tests. This is an exciting time as we finish the first-time production of the complex core stage that will provide the power to send the Artemis I mission to the Moon."

The last piece added to the stage was the engine section located at the bottom of the 212-foot-tall core stage. To complete the structure, technicians bolted the engine section to the stage's liquid hydrogen propellant tank, which was recently attached to the other core stage structures. The engine section is one of the most complicated pieces of hardware for the SLS rocket and is the attachment point for the four RS-25 rockets and the two solid rocket boosters that produce a combined 8.8 millions pounds of thrust. The engine section also includes vital systems for mounting, controlling and delivering fuel from the stage's two liquid propellant tanks to the rocket's engines. This fall, NASA will work with core stage lead contractor, Boeing, and the RS-25 engine lead contractor, Aerojet Rocketdyne, to attach the four RS-25 engines and connect them to the main propulsion systems inside the engine section.

"Boeing expects to complete final assembly of the Artemis I core stage in December," said Jennifer Boland-Masterson, Boeing operations direct at MAF. "After we deliver the stage, NASA will transport it on the agency's Pegasus barge from Michoud to NASA's Stennis Space Center near Bay St. Louis, Mississippi, for Green Run testing. Our team here at Michoud will continue work with NASA to build, outfit and assemble the core stage for Artemis II, the first mission that will send astronauts to orbit the Moon. Lessons learned and innovations developed in building the first core stage are making the second one progress much faster."

During Green Run testing, engineers will install the core stage into the B-2 Test Stand at Stennis for a series of tests that will build like a crescendo over several months. This will be the first fully fueled test of this brand new rocket stage. Many aspects will be carried out for the first time, such as fueling and pressurizing the stage, and the test series culminates with firing up all four engines to demonstrate that the engines, tanks, fuel lines, valves, pressurization system, and software can all perform together as they will on launch day.


The core stage test team recently completed structural testing confirming the stage's liquid hydrogen tank structural design is good for conditions that will be experienced in the rocket's initial configuration, called Block 1, during the Artemis I launch. The 149-foot test article was lifted into a test stand at NASA's Marshall Space Flight Center in Huntsville, Alabama, wh ere engineers put the tank through the paces during 37 separate test cases that simulated the stresses of launch that the SLS rocket experiences during flight. Testing will continue later this year to show the tank's structural design is adequate for future designs of the vehicle as it evolves to a Block IB configuration and missions with more extreme forces.

The SLS team also achieved another recent milestone by completing structural testing for the stage's liquid hydrogen tank. The testing confirmed that the structural design for the tank on the rocket's initial configuration, called Block 1, can withstand extreme conditions during launch and flight. Teams at NASA's Marshall Space Flight Center in Huntsville, Alabama, put a test version of the tank through the paces during 37 separate test cases that exceed what engineers expect the SLS rocket to experience. The final test used 80,000 gallons of liquid nitrogen to simulate the cryogenic conditions, or extreme cold, that the liquid hydrogen tank will experience in flight. Testing will continue later this year to show the tank's structural design is adequate for future designs of the vehicle as it evolves to a Block IB configuration and missions with even greater forces.

In addition to providing propellant and power to get the SLS rocket and Orion spacecraft to space, the core stage houses the flight computers and avionics components that control the first 8 minutes of flight. The avionics system, including the flight computers, completed integrated system level qualification testing showing the components all work together to control the rocket in the Software Integration and Test Facility (SITF) at Marshall. The next step is to test the flight software with all the ground system software, Orion and launch control in the Systems Integration Laboratory at Marshall.

"NASA and our contractor teams are making tremendous progress on every aspect of manufacturing, assembling and testing the complex systems needed to land American astronauts on the lunar surface by 2024," Bassler said. "I am confident this hard work will result in a rocket that can provide the backbone for deep space transportation to the Moon and ultimately to Mars."

NASA is working to land the first woman and the next man on the Moon by 2024. SLS and NASA's Orion spacecraft, along with the Gateway in orbit around the Moon, and the Human Landing System are the backbone for deep space exploration. SLS is the only rocket that can send Orion, astronauts and supplies to the Moon in a single mission

NASA объявило о завершении сборки центрального блока ракеты для полетов на Луну
В ближайшее время инженеры установят четыре двигателя RS-25

ТАСС, 20 сентября. Национальное управление США по аэронавтике и исследованию космического пространства (NASA) завершило сборку центрального блока тяжелой ракеты Space Launch System (SLS), которую намеревается использовать для отправки астронавтов на Луну. Об этом говорится в опубликованном в пятницу сообщении американского ведомства.

Инженеры на сборочном предприятии NASA в Новом Орлеане (штат Луизиана) присоединили к ракете последнюю, пятую часть центрального блока - двигательный отсек. "В ближайшее время там будут установлены четыре двигателя RS-25", - приводятся в пресс-релизе слова руководителя процесса сборки SLS Джули Басслер. "Теперь специалисты ведомства проведут заключительные испытания авионики и силовой установки", - отметила она.
В августе вице-президент США Майкл Пенс на заседании Национального космического совета заявил, что сборка SLS завершится уже в этом году. Испытательный полет SLS изначально планировался на текущий год, но затем был перенесен на вторую половину 2020-го.

NASA весной объявило о том, что новая программа освоения Луны получила название Artemis. Она будет состоять из трех этапов: первый (Artemis 1), предусматривающий непилотируемый полет установленного на SLS корабля Orion вокруг Луны и его возвращение на Землю, запланирован на вторую половину 2020 года. Второй этап (Artemis 2) - облет естественного спутника Земли с экипажем на борту - намечен на 2022 год. На третьем этапе (Artemis 3) NASA рассчитывает осуществить высадку астронавтов на Луну в 2024 году.

В мае президент США Дональд Трамп объявил о намерении направить в бюджет космического ведомства дополнительно $1,6 млрд на программы освоения Луны и Марса. Эту сумму Белый дом запросит у Конгресса в дополнение к $21 млрд, которые будут выделены на финансирование деятельности NASA в 2020 финансовом году.

Media are invited to NASA's Kennedy Space Center in Florida to view the Space Launch System (SLS) core stage pathfinder arrival on board the agency's Pegasus Barge on Friday, Sept. 27 and the unloading and movement of the pathfinder on Monday, Sept. 30. Subject matter experts from the SLS program, Exploration Ground Systems (EGS) program and contractor Jacobs will be available to discuss the use of the pathfinder and the upcoming testing.

The SLS core stage pathfinder is a full-scale mockup that is identical to the core stage in shape, size and weight. The pathfinder, though not actual flight hardware, will provide the EGS team with the opportunity to practice stacking maneuvers and certify the new system inside the Vehicle Assembly Building (VAB) High Bay 3 before Artemis flight hardware arrives next year. Over the next several months, pathfinder will be used to validate ground support equipment and demonstrate how the core stage will be integrated in the VAB – the same process the actual core stage will undergo when being processed for Artemis I.

"...Статья финансирования SLS в следующем году должна вырасти на $1,2 млрд по сравнению с 2019 годом до $2,586 млрд. Из них $300 млн будет потрачено на создание новой верхней ступени EUS, которую НАСА не намерено использовать как минимум до 2025 года. «Орион» получит $1,4 млрд, что лишь немного выше уровня текущего года."
