Обнародованы данные о ходе создания РН семейства СЛС
Космическое агентство США обнародовало данные согласно которым оно осуществило установку самого большого элемента конструкции РН СЛС (бак для хранения жидкого водорода) на испытательный стенд 4693 в Центре космических полетов НАСА им. Маршалла в Хантсвилле, штат Алабама. В ходе испытаний конструкция при помощи гидравлических цилиндров будет подвергнута таким же нагрузкам, которые конструкция будет испытывать в ходе полета. Размер бака составляет 45 метров (габариты стенда 66 метров). Полная длина блока будет составлять 65 метров, диаметр 8.4 метра, ДУ - четыре RS-25.

Boeing employees at NASA’s Michoud facility complete a forward join on the SLS rocket core stage.

Boeing teams working on America’s next great rocket, the Space Launch System (SLS), are now connecting the rocket segments for final assembly.

Boeing workers at NASA’s Michoud facility in New Orleans assembled the top half of the SLS core stage – the intertank, liquid oxygen tank and forward skirt - in a vertical stacking cell. The process is called a forward join. The forward join will then be connected to the bottom half of the rocket – the liquid hydrogen tank and engine section – to complete the 212-foot core stage.

At the same time, production of the second core stage for Exploration Mission 2 is underway.

Once the completed core stage is tested at Stennis Space Center, it will be stacked at Kennedy Space Center with the upper part of the rocket, the Interim Cryogenic Propulsion Stage, and the Orion capsule, and joined to the rocket's twin solid rocket boosters, in preparation for first launch, Exploration Mission 1 (EM1). The SLS will carry to Orion out of Earth’s atmosphere to orbit the moon, in preparation for launching astronauts even deeper into space.

Watch as Crews Lift the SLS Liquid Hydrogen Tank Test Article in Test Stand

NASA's Marshall Space Flight Center

Опубликовано: 1 февр. 2019 г.

To ensure NASA’s Space Launch System rocket is ready for Exploration Mission-1, the first integrated flight that will send the Orion spacecraft beyond the Moon, engineers are performing a series of tests at NASA’s Marshall Space Flight Center in Huntsville, Alabama. Crews loaded the 149-foot liquid hydrogen tank structural test article, the largest piece of structural test hardware for the core stage of SLS, into Test Stand 4693 Jan. 14. Dozens of hydraulic cylinders in the test stand will push and pull on the tank to simulate the stresses and loads it will endure during liftoff and flight. Test Stand 4693 is one of the newest test stands at Marshall, and the liquid hydrogen structural test article is the first piece of hardware to be tested in the stand.

Learn How Engineers Connected the Top of the SLS Core Stage.

NASA's Marshall Space Flight Center

Опубликовано: 7 февр. 2019 г.

This video animation shows how engineers at NASA’s Michoud Assembly Facility in New Orleans connected the liquid oxygen tank with the intertank and the forward skirt to complete the forward join – or the forward part – of the core stage of NASA’s Space Launch System, America’s first deep space rocket to take humans beyond the Moon. Altogether, the structure makes up 66 feet of the total 212-foot-tall core stage. The completion of the forward join marks the beginning of the integration and the assembly of the SLS core stage by NASA and Boeing, the SLS prime contractor.

NASA Marks RS-25 Testing Milestone for New Space Launch System

NASA Stennis

Опубликовано: 28 февр. 2019 г.

On Feb. 28, NASA marked yet another milestone in preparations for the first mission of its new Space Launch System (SLS) rocket, conducting an RS-25 engine test at its highest power level. The 510-second test was conducted on the A-1 Test Stand at NASA’s Stennis Space Center. For the fourth time, NASA powered the engine to 113 percent of its original thrust design, this time for more than 430 seconds, about four times longer than any previous hot fire at that thrust level. This test concluded a series of nine tests that began last August, using RS-25 developmental engine No. 0525, and featured an RS-25 flight engine controller, or “brain” of the engine, that will be used on an SLS mission.

The budget funds “the SLS and Orion crew capsule to support a first uncrewed test launch in the early 2020s” [which sounds like a slip from 2020…]

It defers work on the Block 1B version of the SLS (which uses the Exploration Upper Stage), and instead desires an “annual cadence” of Block 1 SLS missions. Gateway components will be launched “on competitively procured vehicles.”
