NASA's Pegasus Barge arrived at the agency's Kennedy Space Center in Florida on Sept. 27, carrying the 212-foot-long core stage pathfinder for the Space Launch System (SLS) rocket. Weighing in at 228,000 pounds, the pathfinder is a full-scale mock-up of the rocket's core stage and will be used to validate ground support equipment and demonstrate it can be integrated with Kennedy facilities.

After arriving at the Launch Complex 39 turn basin wharf – a docking area initially used during the Space Shuttle Program that has been modified to accommodate SLS hardware deliveries – the pathfinder was moved into the Vehicle Assembly Building (VAB) on Sept. 30, where it will remain for testing for about one month.

While in the VAB, pathfinder will provide NASA's Exploration Ground Systems (EGS) and contractor Jacobs with the opportunity to practice stacking maneuvers in the VAB's High Bay 3 prior to the arrival of the SLS flight hardware that will be processed for the agency's Artemis I mission.

"This will help ensure that all core stage engineers and technicians are trained and certified in preparation for the flight core stage processing," said Jim Bolton, EGS core stage element operations manager at Kennedy. "It's a very significant milestone that will demonstrate the capabilities and ability for KSC to receive, process and integrate that flight hardware."

The core stage – the largest rocket stage in the world and the backbone of SLS – will provide the power necessary to send NASA's Orion spacecraft beyond Earth's orbit and to the Moon. Before it can be brought to Kennedy for processing, the core stage will undergo its first full test with all flight hardware, known as a green run, at the agency's Stennis Space Center in Mississippi. Following this, Pegasus will make its return journey to Kennedy in 2020 – this time, delivering the SLS core stage for launch.

ЦитироватьNASA official hints first SLS launch could slip to mid-2021
by Jeff Foust — October 11, 2019


The acting associate administrator for human exploration and operations at NASA, Ken Bowersox, said that current schedules calling for a late 2020 first launch of SLS are "very, very aggressive" that that the launch may slip well into 2021. Credit: NASA

LAS CRUCES, N.M. — While NASA continues to wait to set a new official date for the first launch of its Space Launch System, an agency official said Oct. 10 that the launch could slip as late as the middle of 2021.

NASA's formal estimate of the first launch of SLS, a mission called Artemis 1, remains late 2020. That date, though, assumes that everything will go exactly as planned for the remainder of the vehicle's development and testing.

"The schedule that we're managing to is very, very aggressive," said Ken Bowersox, acting associate administrator for human exploration and operations at NASA, during a presentation at the International Symposium for Personal and Commercial Spaceflight (ISPCS) here.

That schedule calls for finishing the core stage of the vehicle at the end of this year and shipping it to the Stennis Space Center in Mississippi for a static-fire test known as the Green Run. "In the best case, it's going to be five or six months" of testing there, he said.

He added, though, that there are "risks" to that timeline due to both technical issues, such as the amount of time needed to refurbish the stage after the test, as well as weather that can delay work on the outdoors test stand.

After the Green Run, the stage would be shipped to the Kennedy Space Center for integration with its two solid rocket boosters, upper stage and the Orion spacecraft that will perform an uncrewed test flight in cislunar space.

"We have a chance to actually have a rocket on the pad and launch by the end of next year," he said. "But when you start throwing all those different uncertainties, it's more likely that we will move out into 2021."

Earlier in his speech, he suggested that the Artemis 1 launch could slip well into 2021. "Some time late next year, middle of the year after," he said, "the first uncrewed Orion will be launched out around the moon."

Bowersox's comments are the strongest signal yet that a 2020 launch of the SLS appears unlikely. Slips in the schedule in March prompted NASA Administrator Jim Bridenstine to propose flying what was then known as Exploration Mission 1 on an alternative vehicle to the SLS, a proposal strongly opposed by congressional supporters of the rocket and which the agency ultimately decided not to pursue.

NASA also considered shortening or doing away entirely with the Green Run as a means of saving several months of schedule. That move was opposed by many agency advisors, including the Aerospace Safety Advisory Panel, and Bridenstine announced in July that the agency would go ahead with the Green Run test.

A formal decision on a new launch date, Bowersox said, won't come until the agency hires a new associate administrator for human exploration and operations. Bowersox, a deputy associate administrator, has held the position in an acting capacity since Bridenstine reassigned longtime associate administrator Bill Gerstenmaier three months ago.

"When we name a new [associate administrator], we're going to give that person a chance to look at all of the schedule analyses that have been done, and let them rebaseline the date and cost information," he said.

NASA, though, has not appeared to be in a rush to select a permanent successor to Gerstenmaier. Bowersox noted that, when he testified before a House committee Sept. 18, he estimated that person would be selected "by the end of the year," a schedule he said he was then told by agency leadership was too long. "Now what I say is somewhere between a few weeks and a few months."

Bridenstine, speaking Oct. 10 at SpaceX's headquarters in Hawthorne, California, after a meeting with Elon Musk, praised Bowersox for his interim leadership. "He's doing great work," Bridenstine said, arguing that it would not, at least, delay any commercial crew test flights. "As of right now, I'm very confident we can continue moving forward and not have any delays because of the opening in that position."

Bridenstine hinted that the search for a new associate administrator may soon end. "We will come to a point where we settle on a name, but we're not there yet," he said. "That announcement is not months away, it's weeks away."

Bowersox said he was interested in taking the associate administrator position on a permanent basis. "If I wasn't interested in the job, I wouldn't still be here as the acting" associate administrator, he said. "I'd be happy to serve in the position."

В NASA назвали новую предполагаемую дату запуска самой мощной ракеты в мире
По мнению одного из высокопоставленных чиновников космического ведомства США, первый запуск носителя Space Launch System могут осуществить в середине 2021 года.

В то время как NASA выжидает удачный момент, чтобы установить новую официальную дату первого запуска своей сверхтяжелой ракеты Space Launch System, чиновник агентства Кеннет Бауэрсокс (Kenneth Bowersox) заявил 10 октября, что запуск могут перенести к середине 2021 года. Ранее первый старт хотели выполнить уже в следующем году.

 Причин переноса много, но главная из них связана с высочайшей технической сложностью изделия и рисками, обусловленными данным обстоятельством. «Расписание, к реализации которого мы стремимся, очень и очень агрессивное», — заявил он. Этот график предусматривает завершение строительства основной ступени в конце этого года и отправку ее в Космический центр имени Джона Стенниса в Миссисипи для проведения огневых статических тестов, известных как Green Run.

 Для реализации этого графика существуют риски, обусловленные как техническими проблемами, такими, как количество времени, необходимое для восстановления ступени после испытания, так и погодными условиями, которые могут задержать работу на испытательном стенде на открытом воздухе.

 После Green Run ступень будет отправлена ​​в Космический центр им. Кеннеди для интеграции с двумя твердотопливными ракетными ускорителями, верхней ступенью и космическим кораблем «Орион», который должен будет выполнить испытательный полет.

 «У нас есть шанс установить ракету на площадку и запустить ее к концу следующего года», — говорит Кен Бауэрсокс. «Но когда вы начнете учитывать разные неопределенности, то более вероятным кажется 2021 год».

 Кеннет Бауэрсокс — инженер, офицер ВМС США и бывший астронавт НАСА. Он участвовал в пяти миссиях Спейс шаттл, а также был командиром шестого долговременного экипажа Международной космической станции. Сейчас он исполняющий обязанности заместителя администратора NASA по пилотируемым программам.

 Первый старт ракеты носителя Space Launch System имеет обозначение «Артемида-1»: в рамках него планируют беспилотный облет Луны космическим кораблем Orion и вывод шести нано-спутников CubeSat. Ранее стало известно, что NASA выдало контракт на строительство от шести до двенадцати космических кораблей Orion.

Очевидно, что многочисленные переносы сроков бьют по престижу NASA и нынешнего политического руководства США. Напомним, недавно глава NASA Джим Брайденстайн довольно жестко высказался относительно программы пилотируемых полетов компании SpaceX, указав, что ее реализацию нужно ускорить.

NASA Commits to Future Artemis Missions With More SLS Rocket Stages

NASA has taken the next steps toward building Space Launch System (SLS) rocket core stages to support as many as 10 Artemis missions, including the mission that will carry the first woman and next man to the Moon by 2024.


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.

The agency intends to work with Boeing, the current lead contractor for the core stages of the rockets that will fly on the first two Artemis missions, for the production of SLS rockets through the next decade. The core stage is the center part of the rocket that contains the two giant liquid fuel tanks. Towering 212 feet with a diameter of 27.6 feet, it will store cryogenic liquid hydrogen and liquid oxygen and all the systems that will feed the stage's four RS-25 engines. It also houses the flight computers and much of the avionics needed to control the rocket's flight.

NASA has provided initial funding and authorization to Boeing to begin work toward the production of the third core stage and to order targeted long-lead materials and cost-efficient bulk purchases to support future builds of core stages. This action allows Boeing to manufacture the third core stage in time for the 2024 mission, Artemis III, while NASA and Boeing work on negotiations to finalize the details of the full contract within the next year. The full contract is expected to support up to 10 core stages and up to eight Exploration Upper Stages (EUS).

"It is urgent that we meet the President's goal to land astronauts on the Moon by 2024, and SLS is the only rocket that can help us meet that challenge," said NASA Administrator Jim Bridenstine. "These initial steps allow NASA to start building the core stage that will launch the next astronauts to set foot on the lunar surface and build the powerful exploration upper stage that will expand the possibilities for Artemis missions by sending hardware and cargo along with humans or even heavier cargo needed to explore the Moon or Mars."


An illustration of NASA's Space Launch System (SLS) in the Block 1 configuration, which will carry an Orion spacecraft beyond the Moon, on the mobile launcher. SLS is the only rocket that can send the Orion spacecraft, astronauts and supplies to the Moon on a single mission.

Boeing's current contract includes the SLS core stages for the Artemis I and Artemis II missions and the first EUS, as well as structural test articles and the core stage pathfinder. The new contract is expected to realize substantial savings compared to the production costs of core stages built during the design, development, test and evaluation phase by applying lessons learned during first-time builds and gaining efficiencies through bulk purchases.

"NASA is committed to establishing a sustainable presence at the Moon, and this action enables NASA to continue Space Launch System core stage production in support of that effort to help bring back new knowledge and prepare for sending astronauts to Mars," said John Honeycutt, SLS Program Manager at Marshall. "SLS is the only rocket powerful enough to send Orion, astronauts and supplies to the Moon on a single mission, and no other rocket in production today can send as much cargo to deep space as the Space Launch System rocket.

For the first three Artemis missions, the SLS rocket uses an interim cryogenic propulsion stage to send the Orion spacecraft to the Moon. The SLS rocket is designed to meet a variety of mission needs by evolving to carry greater mass and volume with a more powerful EUS. The EUS is an important part of Artemis infrastructure needed to send astronauts and large cargo together, or larger cargo-only shipments, to the Moon, Mars and deep space. NASA aims to use the first EUS on the Artemis IV mission, and additional core stages and upper stages will support either crewed Artemis missions, science missions or cargo missions.

"The exploration upper stage will truly open up the universe by providing even more lift capability to deep space," said Julie Bassler, the SLS Stages manager at Marshall. "The exploration upper stage will provide the power to send more than 45 metric tons, or 99 thousand pounds, to lunar orbit."

The Space Launch System rocket, Orion spacecraft, Gateway and Human Landing System are part of NASA's backbone for deep space exploration. Work is well underway on both the Artemis I and II rockets, with core stage assembly nearly complete at Michoud. Soon, the stage will be shipped to NASA's Stennis Space Center near Bay St. Louis, Mississippi, where it will undergo Green Run testing, an integrated test of the entire new stage that culminates with the firing of all four RS-25 engines. Upon completion of the test, NASA's Pegasus barge will take the core stage to NASA's Kennedy Space Center in Florida where it will be integrated with other parts of the rocket and Orion for Artemis I. Boeing also has completed manufacturing most of the main core stage structures for Artemis II.

The Artemis program is the next step in human space exploration. It's part of NASA's broader Moon to Mars exploration approach, in which we will quickly and sustainably explore the Moon and use what we learn there to enable humanity's next giant leap, sending astronauts to Mars.

The EUS turns SLS Block 1 into Block 1B (105mT capable vehicle). A downside is the rocket will be too tall for Mobile Launcher (ML-1) currently being tested at 39B. So NASA needs to build another (ML-2). Will take several years and lots of $'s to build.
