The pathfinder is a full-scale mock-up of the rocket's core stage. It was used by the Exploration Ground Systems Program and its contractor, Jacobs, to practice offloading, moving and stacking maneuvers inside the Vehicle Assembly Building using ground support equipment to train employees and certify all the equipment works properly. The pathfinder was at Kennedy for about a month.

The barge is carrying the pathfinder back to the agency's Michoud Assembly Facility in Louisiana.

Fr om Wind to Data, in No Time Flat: Accelerating Spacecraft and Aircraft Design

NASA is preparing to send astronauts to explore the Moon's south pole within the next five years as part of the Artemis program. Knowing that time is of the essence, NASA aerospace engineer Nettie Roozeboom thought of an idea that could speed up significantly the design of rockets, lunar landers and other spacecraft to support lunar exploration. By linking in real time two NASA facilities – one for advanced aeronautics testing, the other for powerful analysis of the results – her method could define a new way of doing business in the world of spacecraft and aircraft design. Last month, she showed how it could work during the latest tests of NASA's new rocket, the Space Launch System, or SLS.


This video is a visualization of fluctuating pressure measurements affecting the Space Launch System during a wind tunnel test to simulate the launch of the rocket. Aircraft and spacecraft must be designed to withstand these rapidly changing forces, called buffeting, or risk being shaken to pieces. The changes in pressure are visualized as colors (yellow: higher-than-average pressure; blue: lower-than-average pressure) and represent the moments before the rocket reaches supersonic speeds. Pressure-sensitive paint makes such accurate measurements possible.

Roozeboom is in the perfect spot to bridge the worlds of testing rocket designs and crunching data.

In the wind tunnels at NASA's Ames Research Center in California's Silicon Valley, she helps aerospace designers – whether from NASA, other government agencies or private companies – study their vehicles' performance by simulating the conditions expected in flight. From an experimental "green" aircraft concept designed by Boeing to reduce both emissions and noise to a launch abort system that would carry astronauts to safety if needed on the launch pad – Roozeboom has helped many designs get on their way.

Down the street at Ames, her neighbors at the NASA Advanced Supercomputing facility, or NAS, work with computer simulations and analyze complex data sets using one of the world's most powerful supercomputers.

A real-time connection between the two disciplines could become an important tool for many. Traditionally, aerospace design teams carry their data from a wind tunnel test back to their workplace on a stack of hard drives, wh ere it then takes months to analyze. If they realize they missed something, and more data would've been valuable, Roozeboom's facility is in such high demand she won't have a spot for them to do another test run until 2021—two years from the original test. With NASA's schedule to land the first astronauts on the lunar surface in 2024, she knew this two-year design cycle wouldn't fly.

That's especially critical with all the new traffic she anticipates in the wind tunnels. As the first major step to returning astronauts to the Moon, NASA is working with nine American companies on delivery services to the lunar surface, and Roozeboom expects they'll all come through her facility.

"The way I see it is: We, NASA, have asked you to do this, so how can we help you get there?" Roozeboom said. "I take it as my responsibility to go create the tools, help them connect to the right talent, and together we can save time."

The high-tech paint acts as a pressure sensor covering the entire surface of the rocket during tests simulating its launch to space. A September 2019 test at Ames let researchers see and study in more detail than ever before the chaotic airflow SLS will encounter in flight.

In September 2019 at Ames, Roozeboom put her plan to the test with SLS. This rocket will send the Orion spacecraft to the Gateway in lunar orbit, from wh ere the first woman and next man will head to the surface of the Moon aboard a human landing system. The design of SLS is also being tweaked for other missions and types of cargo. For flights that will deliver goods to the Moon, the SLS team needed to test the design for the rocket's fairing, or nose, specially made to send cargo to deep space. The tests will ensure the rocket will fly safely and protect the cargo inside.

Roozeboom's job, specifically, is to measure shaking caused by strong and quickly changing pressure from the air a vehicle is pushing through as it travels through the atmosphere to get to space. This tells designers how to build their vehicle to withstand the shaking of a real flight. During her team's wind-tunnel tests, high-speed cameras captured the changing glow of a high-tech paint that reveals rapidly fluctuating pressure during the rocket's simulated ascent. The data was saved to a rack of hard drives, but, for the first time, it didn't stop there.

During a first-of-its-kind demonstration, data from the wind tunnel was sent directly to the NASA Advanced Supercomputing facility for real-time visualization of the results. This event illustrated the power of connecting the two facilities: By getting a look at the data right away, future design teams will be able to request immediate adjustments to test conditions in the wind tunnel, ultimately speeding up aircraft and spacecraft design.

The demonstration, which Roozeboom named Red Rover – a nod to the children's recess game – sent as much as 400 terabytes of data straight from the wind tunnel to the supercomputer. That's 800 times more than the laptop that typed up this story can hold and a record for the live transfer of data like this for immediate processing. Collaborating with the supercomputing experts at the NAS facility was essential for handling it all. They had taken the wind tunnel experts' usual software for processing pressure-sensitive paint data and optimized it for real-time visualization.

The result: NAS's supercomputer churned through the data coming in from the wind tunnel and revealed a visualization of the results, practically on the spot. The SLS design team watched on the 1/4 billion-pixel hyperwall – a floor-to-ceiling wall of screens – and immediately consulted with the experts at Ames. When the test conditions didn't provide precisely the information needed, they were adjusted with a quick message over to the wind tunnel, and new data was collected. All without further ado or delay.

"This could be a tremendous benefit for programs early in the design cycle," said Thomas Steva, an aerodynamics engineer on the SLS team at NASA's Marshall Space Flight Center in Huntsville, Alabama who worked on the Red Rover project. "That's a time wh ere high-fidelity data is typically sparse."

Roozeboom will now work closely with SLS team members at two other NASA centers – Marshall and Langley Research Center in Hampton, Virginia – to understand how the data should be processed and packaged to best meet their needs. This will help define what NASA's commercial partners in both aviation and spacecraft design will need in the future, as the agency develops the new state of the art. Thanks to dual expertise in wind tunnel testing and advanced computing, designs for the Artemis program and more can be forged in real time.

The White House puts a price on the SLS rocket—and it's a lot

After the Senate Appropriations Committee released its fiscal year 2020 budget bill in September, the White House Office of Management and Budget responded with a letter to share some "additional views" on the process. This letter (see a copy), dated October 23 and signed by acting director of the White House budget office Russell Vought, provides some insight into NASA's large Space Launch System rocket.

Congress has mandated that NASA use the more costly SLS booster to launch the ambitious Europa Clipper mission to Jupiter in the early 2020s, while the White House prefers the agency to fly on a much-less-expensive commercial rocket. In a section discussing the Clipper mission, Vought's letter includes a cost estimate to build and fly a single SLS rocket in a given year—more than $2 billion—which NASA has not previously specified.

All Four Engines Are Attached to the SLS Core Stage for Artemis I Mission


 Back to Gallery

All four RS-25 engines were structurally mated to the core stage for NASA's Space Launch System (SLS) rocket for Artemis I, the first mission of SLS and NASA's Orion spacecraft. To complete assembly of the rocket stage, engineers and technicians are now integrating the propulsion and electrical systems within the structure. The completed core stage with all four RS-25 engines attached is the largest rocket stage NASA has built since the Saturn V stages for the Apollo Program that first sent Americans to the Moon. The stage, which includes two huge propellant tanks, provides more than 2 million pounds of thrust to send Artemis I to the Moon. Engineers and technicians at NASA's Michoud Assembly Facility in New Orleans attached the fourth RS-25 engine to the rocket stage Nov. 6 just one day after structurally mating the third engine. The first two RS-25 engines were structurally mated to the stage in October. After assembly is complete, crews will conduct an integrated functional test of flight computers, avionics and electrical systems that run throughout the 212-foot-tall core stage in preparation for its completion later this year. This testing is the first time all the flight avionics systems will be tested together to ensure the systems communicate with each other and will perform properly to control the rocket's flight. Integration of the RS-25 engines to the massive core stage is a collaborative, multistep process for NASA and its partners Boeing, the core stage lead contractor, and Aerojet Rocketdyne, the RS-25 engines lead contractor.

RS-25 ENGINES SUCCESSFULLY INTEGRATED WITH SPACE LAUNCH SYSTEM

Imagine! The ground rumbling, your heart pounding with excitement and then you see a wondrous sight, a bright orange rocket rising into the sky.  Thanks to the hard work by the NASA, Boeing and Aerojet Rocketdyne teams, we are one step closer to seeing that vision become a reality.

On Nov. 6, 2019 the last of four RS-25 engines were successfully integrated with the first Space Launch System (SLS) rocket at NASA's Michoud Assembly Facility (MAF). These engines will help send the first Artemis lunar mission to space.

RS-25 core stage integration

Connecting the engines to the core stage was not a simple task.  As Bill Muddle, RS-25 field integration engineer, explained, "The back of the SLS rocket is huge, and then you look at the access space you have available to actually install the engines and you realize you can take nothing for granted. You can apply a lot of lessons fr om the Space Shuttle program, but that is just a baseline; you've got to adapt to the unique aspects of SLS."


During the Space Shuttle program, technicians had access to 360 degrees around the Space Shuttle Main Engines, which have been upgraded and renamed the RS-25 engines. But with SLS, you only have half of that amount, making it a choreographed dance of five technicians working in concert to install each engine and properly align them to ensure that when the vehicle gimbals all four engines, they don't touch.

"It is easy to forget the sheer size of four engines clustered together," said Muddle. "I'm fortunate to have seen the last engine leave Kennedy Space Center for upgrades at Aerojet Rocketdyne's facility located at NASA's Stennis Space Center, and now I've seen the first flight engines for SLS arrive and be installed at the Michoud Assembly Facility. I have a lot of pride in seeing the marriage of these two amazing programs," added Muddle.

The RS-25 engines for the first flight of SLS have been upgraded since the shuttle to ensure that they can operate in the unique environment of this rocket. For example, all of the engines received new controllers, ensuring that each engine is able to relay real-time performance data to the rocket and is able to regulate thrust and propellant mixtures while the vehicle is making its eight and one-half minute climb into space. The engines have to operate at higher power levels for the SLS compared to the shuttle, and the new rocket delivers propellant to the engines at different pressures and temperatures. Additionally, insulation was added to each engine nozzle to protect and prevent them from overheating during launch. These and dozens of other changes had to be assessed analytically and then verified safe by full-scale engine hot-fire tests.

]Now that the SLS team has installed all four engines onto the core stage, they can turn their attention to final integration testing of the vehicle to make sure that the engineers can obtain a good signal from the ground operators to the vehicle and from the vehicle to the engine controllers. Once that is complete, the team will start preparing the first SLS core stage for Green Run testing at NASA's Stennis Space Center in Mississippi. All four engines will fire during this test.

Once Green Run testing is complete, the core stage will be shipped to Kennedy Space Center in Florida, wh ere it will be joined with the Interim Cryogenic Propulsion Stage, the stage that provides the power to send the Orion spacecraft to the Moon. Here, the entire rocket will be assembled and prepared for launch. Then you will no longer have to imagine the ground rumbling, heart-pounding excitement of a rocket launch – the bright orange rocket will actually be rising into the sky to open a new chapter in the story of human exploration.

NASA установила последний, четвертый двигатель на сверхтяжелой ракете для полетов на Луну
       Вашингтон. 8 ноября. ИНТЕРФАКС - На первой ступени сверхтяжелой ракеты-носителя SLS, с помощью которой в 2024 году планируется осуществить запуск пилотируемого корабля Orion на Луну, установлен последний, четвертый двигатель RS-25, сообщил глава Национального управления США по аэронавтике и исследованию космического пространства (NASA) Джим Брайденстайн.
      "Первая ступень ракеты SLS высотой 212 футов (65 метров - ИФ) со всеми четырьмя подсоединенными двигателями RS-25 является самой большой с тех пор, как NASA построила носитель Saturn V для корабля "Аполлон" (для предыдущих пилотируемых полетов к Луне - ИФ), - написал Брайденстайн.
       На опубликованной им в твиттере фотографии видны все четыре двигателя RS-25, подсоединенные к первой ступени ракеты-носителя.
       Ранее американское космическое агентство сообщило, что NASA и компаниям Boeing и Aerojet Rocketdyne еще предстоит интегрировать двигательную и электрическую системы общей конструкции для завершения инсталляции.
       Ракетные двигатели RS-25 разрабатывались специально для американской сверхтяжёлой ракеты SLS. Аналогичные установки уже были использованы на космическом корабле Space Shuttle. Версия RS-25 для SLS имеет большую тягу и новую систему управления.
       Как сообщалось, в сентябре была завершена сборка и соединение всех пяти секций первой ступени сверхтяжелой ракеты-носителя SLS.
       Ожидается, что первая ступень SLS окончательно будет готова в декабре, после чего начнутся ее испытания, которые продлятся несколько месяцев.
       SLS (Space Launch System) - американская сверхтяжёлая ракета-носитель, разрабатываемая NASA для пилотируемых миссий за пределы околоземной орбиты. Первый беспилотный запуск с миссией ("Артемида-1") запланирован на середину 2020 года, а первый пилотируемый Artemis 2 - на 2023 год. В рамках программы Artemis ракета SLS будет использоваться для запуска пилотируемого корабля Orion, в том числе на Луну.
       Система в базовой версии будет способна выводить 95 тонн груза на опорную орбиту. Дальнейшее развитие конструкции ракеты-носителя должно обеспечить увеличение грузоподъёмности до 130 тонн. Она станет самой мощной космической ракетой в мире.

With the last of four Aerojet Rocketdyne engines successfully installed on the first Space Launch System core stage structure, Boeing is launching a Final Integrated Functional Test (FIFT) at Michoud Assembly Facility in New Orleans.

As part of FIFT, engineers and technicians will integrate the propulsion and electrical systems within the structure, then test the flight computers, avionics and electrical systems that run throughout the stage. It's the first time all the flight avionics systems will be tested together to ensure the systems communicate with one another and will perform properly to control the rocket's flight on NASA's first Artemis mission.

Meanwhile, technicians at Stennis Space Center in Mississippi are preparing the massive B2 test stand for the system's first full test fire, known as Green Run. A Stage Controller team in Florida has finished development of the first phase of the software system that will control the core stage on the test stand.

During Green Run, the four RS-25 engines at the bottom of the 212-foot core stage will fire nonstop for 8.5 minutes, providing 2 million of the 8.8 million pounds of maximum thrust at liftoff. That test fire will validate the system to ensure a safe and reliable launch fr om Kennedy Space Center next year, when the rocket will carry the Orion space capsule out of Earth's orbit for its trip around the moon and back.

The core stage is the largest rocket stage ever built for NASA, manufactured in the same factory wh ere the Apollo-era Saturn V rocket stages were built.

NASA Certifies SLS Rocket Laboratory To Test Flight Software for Artemis I

To launch the Artemis I Moon mission, NASA's powerful Space Launch System (SLS) rocket must go fr om 0 to more than 17,000 miles per hour. The rocket's flight software and avionics systems control all that power to ensure the rocket and NASA's Orion spacecraft make it to space. The SLS avionics and flight software came a step closer to the Artemis I mission when NASA certified the Systems Integration Laboratory for final integrated avionics and flight software testing Nov. 14.

"The System Integration Lab's test environment is the most accurate representation of the rocket's entire avionics and software system," said Dan Mitchell, lead SLS integrated avionics and software engineer. "Certification means the lab has completed a series of tests and analyses to assert that the facility, its simulation environment and the avionics and flight software have been properly integrated and ready for formal system verification testing."

This lab at NASA's Marshall Space Flight Center in Huntsville, Alabama, not only includes the flight computers and avionics identical to the core stage avionics but also includes emulators for the rocket's boosters and engines, the Launch Control Center and Orion. Now that the lab is ready, software engineers can test the software both under normal and unplanned scenarios.

Using unique software programs, engineers in the lab create real-time launch vehicle simulations for the rocket's extensive and incredibly intricate flight software and avionics hardware. These simulations include numerous nominal and off nominal real-time pre-launch and ascent SLS mission scenarios.

Equipped with two propellant tanks that can hold a combined 733,000 gallons of fuel and four RS-25 engines, the 212-foot-tall core stage serves as the powerhouse of the rocket. The core stage, along with the two, five-segment solid rocket boosters, produces more than 8.8 million pounds of thrust to launch it and NASA's Orion spacecraft to the Moon.

The internal flight software and avionics outfitted throughout the boosters and core stage operate with three SLS flight computers and interface with the avionics systems to control all that power and safely guide the rocket beyond Earth's orbit. The software also works with software for the Exploration Ground Systems team at NASA's Kennedy Space Center in Florida, from wh ere SLS will launch.

 "The flight software and avionics systems are considered the brain and nervous system of the rocket," Mitchell said. "They control the rocket from launch through the first eight minutes of flight, and the test scenarios we create in the lab can simulate any part of an SLS rocket's launch or even the entire mission."

In the same room as the lab, the Software Integration and Test Facility integrates and tests hardware for the avionics systems in the core stage of the rocket. These two facilities provide a comprehensive scope of the rocket's "internal organs" as teams of engineers run hundreds of virtual launches to verify the rocket's thousands of functional lines of code to evaluate how it will perform in space.

The facilities contain a complete set of avionics and software for the rocket's core stage, boosters and engines to support end-to-end avionics and software system testing.

"Across the lab in roughly the same positions as they would be inside the core stage, SLS avionics boxes are mounted around a cylinder frame that matches the size of the rocket," said Lisa Espy, SLS core stage avionics lead. "Inside the skeleton of the rocket, the boxes are even connected with the same sized cables and connectors that will be used on the flight vehicle itself."

With the certification of the lab complete, formal system testing will be conducted in two phases. First, engineers and developers will focus on the critical avionics hardware and software for flight. Following that, testing will be conducted on the engineering and developmental data acquisition hardware and the hardware for the imagery and flight safety systems.

Althought manufacturing hardware generally garners the most attention, development and testing of the flight software are two of the more technically challenging aspects of the rocket's design.

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