SLS

This isn’t a space transportation system; it’s a cathedral:

The foundation that was already there at Michoud was too weak to support the tool. We had quite a job to reinforce it, to dig it out and then put it back so it could hold up the Vertical Assembly Center. To give you context for the magnitude of the new foundation, Louisiana is not known for its hard soil, and the new foundation that we laid for the Vertical Assembly Center would hold the largest building in downtown New Orleans, 1 Shell Square.

For a program that’s likely to fly, at best, twice.

SpaceX In New Mexico

I had speculated after the almost-successful drone ship landings that SpaceX had abandoned plans to do flight testing at Spaceport America, but apparently that’s not the case:

The original plan was to use the site for test flights of the second F9R Development Vehicle, known as F9R Dev2, a follow on vehicle from the impressive Grasshopper and F9R Dev1 vehicles that paved the way for the propulsive landing attempts.

Those vehicles were tested at SpaceX’s McGregor test site in Texas, but were restricted by an altitude ceiling, resulting in the decision to conduct tests at Spaceport America, at much greater altitudes.

Those tests will be used to find hardware limits, such as how many cycles can be put on a stage, while the second successfully recovered booster would provide the role of qualification testing.

Should the recovery efforts progress, the first launch of a reused booster is likely to occur in late 2016.

Interesting. What I don’t understand is why the helium tanks are a concern for the Turkmenistansat mission, but not for CRS.
