Gerstenmaier -- expect to ship SLS core to Stennis in Dec. Looking at Green Run test.
EM-1 could be in late 2020 but more likely "some time in 2021." EM-2 sometime in 2022, not dependent on when EM-1 takes place. EM-3 in 2024, that's the landing mission.

Engine Installer for Space Launch System Arrives at Kennedy Space Center



One of the larger pieces of ground support equipment that will be used to prepare NASA's Space Launch System (SLS) rocket for its launch on Exploration Mission-1 arrived April 25, 2019, at the agency's Kennedy Space Center in Florida.

The engine vertical installer arrived at the center from the manufacturer, Precision Fabrication and Cleaning in Canaveral Groves. The new equipment will be ready for preflight processing in the event one of the four RS-25 engines on the core stage of the rocket needs to be replaced. This would be the first time that Kennedy's engineers and technicians will install engines in a vertical configuration on a space vehicle. The engine installer has its own dedicated platform measuring 30 feet wide by 30 feet long by 15 feet tall.

During launch of the SLS and Orion spacecraft, the four core stage engines will provide 512,000 pounds of thrust each to lift the rocket and Orion spacecraft off Launch Pad 39B at Kennedy. The uncrewed Orion will travel on a three-week test mission thousands of miles beyond the Moon and back to Earth for a splashdown in the Pacific Ocean.

SLS Begins Insulation Process for Booster Segments for Second Flight


Back to Gallery

NASA and Northrop Grumman technicians in Promontory, Utah, have applied insulation to the final booster motor segment for the second flight of NASA's deep space rocket, the Space Launch System, and NASA's Orion spacecraft. The insulation, applied to the interior of each steel motor segment, protects the casing from the heat generated by the propellant during launch and flight. The twin, five-segment solid rocket motor boosters for SLS are the largest, most powerful solid propellant boosters ever built. SLS uses both liquid and solid propellant to provide the thrust needed to launch the vehicle and send it to space. The boosters provide more than 75% of the total thrust at launch and into the first two minutes of flight. Five motor segments are stacked together to create a single, very large motor for each booster. The manufacture and checkout of all 10 motor segments for the first test flight of SLS and Orion were completed earlier this year.

NASA is charged to get American astronauts to the surface of the Moon by 2024. SLS and the Orion are our backbone for deep space exploration. SLS and Orion will launch from NASA's Kennedy Space Center in Florida on missions to the Gateway in lunar orbit. NASA is targeting 2022 to test SLS with astronauts aboard the Orion spacecraft.

Ученые планируют отправить дрожжевые грибки в дальний космос

Дрожжевые грибки двух видов доставит на околосолнечную орбиту микроспутник BioSentinel

НЬЮ-ЙОРК, 22 мая. /ТАСС/. Национальное управление по аэронавтике и исследованию космического пространства (NASA) планирует уже в будущем году отправить живые организмы в дальний космос. Как сообщил во вторник интернет-портал Space.com, сотрудники NASA работают над созданием космического аппарата BioSentinel массой 14 кг, на борту которого на околосолнечную орбиту будут отправлены клетки дрожжевых грибков двух типов, причем один из них более устойчив к воздействию радиации, чем другой.

BioSentinel и 12 других микроспутников планируется вывести на орбиту в середине 2020 года ракетой-носителем Space Launch System (SLS) в рамках исследовательской программы Artemis 1 в качестве полезной нагрузки. Научная информация с него, как ожидается, будет поступать на протяжении 9-12 месяцев. В течение всего полета ученые будут следить за размножением дрожжевых грибков и одновременно наблюдать за состоянием точно таких же образцов, находящихся на Международной космической станции, где уровень радиации значительно ниже, чем в открытом космосе.

Кроме того, как сообщил Space.com, в Национальной лаборатории в Брукхейвене (штат Нью-Йорк), занимающейся проблемами ядерной физики, образцы дрожжевых грибков будут подвергнуты очень сильному воздействию радиации.

"Важно то, что процесс восстановления ДНК у дрожжевых грибков во многом похож на такие же процессы в организме человека, - привел Space.com мнение специалистов NASA. - Результаты исследований на BioSentinel сыграют очень важную роль при оценке последствий воздействия радиации на организмы".

SLS будет выводить в космос разрабатываемый сейчас пилотируемый корабль Orion. Планируется, что свой первый полет без экипажа с помощью нового носителя он совершит в 2020 году: облетит Луну и вернется на Землю. Среди микроспутников, которые, как ожидается, будут выведены на орбиту в ходе первого пуска ракеты-носителя - Lunar Flashlight и Lunar IceCube, предназначенные для поиском следов водяного льда на поверхности Луны, а также микроспутник с солнечным парусом, который будет направлен к одному из сближающихся с Землей астероидов.

NASA Reaches New Milestone on Complex, Large Rocket

NASA achieved a significant milestone in manufacturing the first large, complex core stage that will help power the Space Launch System (SLS) rocket on upcoming missions to the Moon. NASA and lead contractor Boeing have assembled four-fifths of the massive core stage needed to launch SLS and the Orion spacecraft on their first mission to the Moon: Artemis 1.

The Artemis program will send the first woman and the next man to the Moon by 2024 and develop a sustainable human presence on the Moon by 2028. The program takes its name fr om the twin sister of Apollo and goddess of the Moon in Greek mythology.

"This milestone brings the Space Launch System closer to launching the first Artemis mission," said John Honeycutt, SLS program manager. "The SLS rocket team is laser focused on building the rocket not only for the first flight but also rockets for the second and third Artemis missions that will send astronauts to the Moon."

At approximately 190 feet, about the size of 12 cars parked end-to-end, the stage in its current configuration is the largest rocket stage the agency has built since the Saturn V stages that first sent humans to the Moon nearly 50 years ago. The completed core stage, which includes two propellant tanks as well as four RS-25 engines, will tower at 212 feet. It, along with the twin five-segment solid rocket boosters, will produce the majority of the power to send the SLS and Orion to space.

"Building and assembling this massive integrated propulsion and avionics stage for the world's most powerful rocket, the only launch vehicle that can return astronauts to the Moon, is an engineering feat," said Julie Bassler, SLS stages manager. "To manufacture the Space Launch System, we are working with more than 1,000 companies across the country. It's truly America's rocket." 

This significant program milestone comes after crews completed the second of three major activities to join the liquid hydrogen fuel tank to the upper part of the core stage. The upper part is made up of three previously connected large structures: the forward skirt that houses the rocket's flight computers, the liquid oxygen propellant tank, and the intertank that holds more avionics and attaches to the rocket's powerful boosters. Technicians horizontally connected the liquid hydrogen tank to the intertank using 360 bolts. NASA and Boeing, the SLS prime contractor, will now complete outfitting the engine section before integrating it, along with the four RS-25 engines, to the rest of the stage, completing the immense core stage in its entirety.

In response to President Trump's charge to return Americans to the Moon by 2024, engineers and technicians revised the core stage assembly plan to mate the individual structures horizontally rather than vertically. These milestones — combined with new production tools and the team's responsiveness — keep core stage production on track for completion by the end of the year.

"NASA is constantly looking for ways to get work done more efficiently so that we can get astronauts landing on the Moon by 2024," said Ben Birkenstock, the SLS stages vehicle assembly lead. "The NASA and Boeing team is learning while building this first core stage. The decision to integrate the core stage structures horizontally demonstrates our efforts to continuously improve our operations."

The SLS team continues to make progress on other elements for the rocket's first three missions. In April, the last of 16 RS-25 engines from the space shuttle program passed inspection, capping a 51-month acceptance test series at NASA's Stennis Space Center  near Bay St. Louis, Mississippi and clearing all engines suitable for flight. The manufacture and checkout of all 10 motor segments for the twin boosters on the first Artemis flight were completed in January. NASA and Northrop Grumman technicians in Promontory, Utah, applied insulation to all the booster segments for Artemis 2 in the spring. The solid rocket boosters and four RS-25 engines produce a combined thrust of 8.8 million pounds during launch and flight.

Other parts of the rocket for the first flight, like the launch vehicle stage adapter and the solid rocket boosters, will soon be delivered to NASA's Kennedy Space Center in Florida. The interim cryogenic propulsion stage that will give NASA's Orion spacecraft the push needed to get to the Moon and the adapter that will connect that stage to the spacecraft have already been delivered to Kennedy.

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

Structural Testing of the World's Largest Rocket Stage



On June 11, technicians at NASA's Marshall Space Flight Center in Huntsville, Alabama, started structural testing on the liquid hydrogen tank, the largest piece of structural test hardware for NASA's Space Launch System (SLS) core stage. These tests along with other core stage testing will help ensure the success of the first and subsequent flights of the SLS and Orion's spacecraft. Dozens of hydraulic cylinders in Marshall's Test Stand 4693 will push and pull on the giant tank, subjecting it to the same stresses and forces it will endure during liftoff and flight, to test its strength and to ensure it is safe to fly. The test hardware is structurally identical to the flight version of the liquid hydrogen tank that will comprise two-thirds of the core stage and hold 537,000 gallons of liquid hydrogen cooled to minus 423 degrees Fahrenheit.
