Mobile Launcher (ML) moves to launch pad
Pad B doesn't quite look so sad now does it?

I'd like see an empty launcher on the pad because the rocket just left, rather than because the rocket hasn't been built yet.

Check out this PDF starting on page 5. I was there in 1978 for the testing and I felt the vibration moving the whole stack... it was really neat.

Too bad Guenter wasn't there to kick the tires. I really miss him.

Did they build also a new crawler or is this still the old version with some modifications?

It was one of the two same crawler-transporters previously used during Apollo and space shuttle, without modification.

Just to follow-up, the Apollo and space shuttle-era crawlers will be undergoing a number of upgrades to support the Space Launch System.

For example, their driver cabs and engineering room will be swapping out their analog controls for touch screens. They'll also be receiving new generators, rollers and hydraulic lifts to meet the requirements of the new launch vehicle.

It would be great if they could set up a display with the removed parts as a sit in cab.

Is there any particular reason why they painted the SLS launch tower grey instead of red like the Apollo launch towers?

That would be a great thing to see if they could put it in at one of the KSC displays. I assume the ML is automatic. It would be funny to find out that they drive it using stick shift.

You can see the driver's cab controls as part of our article and photo gallery for the 40th anniversary of the crawler's use.
"We had a joystick up there [in the driver's cabin] during my days," explained Sylvan "Skip" Montagna, a former Bendix employee who drove the crawlers during Apollo. "Today I understand they have little knobs up there. We had the experience of having the controls that were built for it.

As [crawler engineer] Bill [Clemens] said, most of them didn't work at the time, and you've got to appreciate this is a machine [that is] one of a kind so all the controls they built for it, they really didn't work right. As time goes on, we kind of refined them and told the engineers what we'd like to have and they'd refine them," said Montagna.

This Florida Today article says that the other crawler-transporter (CT-1) is being mothballed, in addition to Pad 39A and one of the VAB High Bays.

Why should they be in the first place? Why does it have to be like the past? Are any of the other launch towers at the Cape still red? No, because that red lead anti corrosion paint is seldom used anymore due to toxicity.

You got to let go of the past and move on. Apollo processes and technology are old and arcane and not applicable.

Careful how you report what this article states as it also adds "...available for commercial use."

So while NASA itself may not intend to use them, others may.

Just to underscore this, NASA released these graphics on Feb. 15:

An artist's concept shows a possible layout of a commercial spacecraft and rocket using facilities inside the Vehicle Assembly Building at NASA's Kennedy Space Center in Florida as the center undergoes a transformation into a multi-user spaceport. At left is the Space Launch System, or SLS, currently under development by NASA. At right is a generic rocket and spacecraft design indicative of the likely arrangement of such a vehicle.

Of course, this is tangential to the development of the SLS mobile launcher...

All times are CT (US)
