Mobile Launcher Test Drive Customs SLS One Step Closer to Exploration Mission-1

A Chinese adage roughly says: "A journey of a thousand miles begins at one step." While this adage is true for the Earthly undertakings, it is also fit for launch by NASA 's Space Launch System ( SLS ).

Before the super-heavy-lift missile can ascend to Mission on Mission Mission 1 ( EM-1 ), it must first ascend the 4.4 miles (7, 24 kilometers) drive from the Vehicle Assembly Building ( VAB ) to Launch Pad 39B .

In preparation for the flight, engineers and technicians took the 11 million pound (4,99 million kilogram) Mobile Launcher (ML) on its maiden voyage to the Fit Check launch site for the Exploration Ground Systems [196590000] the almost 380-foot (115.8 meters) tall structure. The two-day operation represents an important milestone for the program.

"The mobile launcher is being postponed to launch the next major program phase for verification and validation of all systems when they are running Pad and VAB systems, "said Cliff Lanham, senior project manager for the mobile carrier, in a publication published by NASA.

The ML will remain at LC-39B for several days, while engineers test network connections integration into key hardware such as noise suppression and environmental control systems.

Once the controls are completed, the ML travels back to the VAB to begin testing and exams within the world's tallest single-story building for a year

Although it's the first time that the hardware has made the trip to Pad 39B In its SLS configuration, it actually marks the second ML's journey to the launch site. Prior to the cancellation of the Constellation program, the ML, which was on the multi-lane Crawler Transporter (CT), made the trip to Pad 39B to make similar fit checks for the Ares I rocket.

The Constellation Program was canceled, along with the Ares I launcher, by the Obama administration in 2009. Parts of the Constellation were rescued (Orion spacecraft) with others, namely the Ares V super-heavy-lift missile, were redefined and renamed (a modified version of

The ML tests are conducted both on-site at Pad 39B and the Young-Crippen Firing Room at the Kennedy Launch Control Center (LCC).

While there were some early reports that the ML had a significant lean, or distraction that might have influenced the alignment of important umbilical connections and access arms, it seems that 19659006] May Have Been Exaggerated [1 9659020] After these questions have been clarified, engineers and technicians should start working on the ML at High Bay 3 in the VAB

At present, EM-1 is expected to take place by 2020 If everything goes on As planned, EM-2 will return NASA astronauts to space missions in 2023.

"These tests are needed to make sure that the systems work as planned and that the systems perform as expected under test conditions," Lanham concluded.
