Video: Former shuttle engine test-fired

NASA has declared assembly complete on the core stage for the first Space Launch System heavy-lift rocket in New Orleans, signaling a long-awaited transition from manufacturing to testing as the core stage is set to move to the nearby Stennis Space Center in Mississippi for a hold-down firing next year of its four shuttle-era main engines.

Weeks after leaving its factory in New Orleans, the core stage for NASA’s first Space Launch System flight has been raised into a test stand at the Stennis Space Center to begin a series of checkouts culminating in an eight-minute engine-firing later this year.

NASA’s heavy-lifting mega-rocket and its ground support systems at Kennedy Space Center in Florida will not be ready for launches until at least mid-2018, even with extra funding approved by Congress, the space agency’s senior human spaceflight official told lawmakers.
