SLS SRB QM-2 Static Fire Test

[VaPaL]

Static test of the SLS SRB Qualification Motor - 2 (QM-2). QM-1 was to test at maximum launch temperature, 32°C, this was to test at minimum, 4°C. The test was performed today (2016/06/28) at 15:05 UTC (May had some delay).

Does a max launch temp of 32°C seem a little low to anyone else? Daytime temps in Florida can easily exceed that in the summer months. . .

@Ten Key Yeah, I thought the same, but I just double checked it and it's right. But I think it was the same for the Space Shuttle or should be somewhhat close to it, since this SRB is a modified and updated version of the Shuttle's one. If fact, four of the five segments of this SRB were from a Shuttle SRB, and IIRC flown ones.
