When helium expands, it heats.

With such a precise number like 68 days, looks like they finally are getting that schedule fixed and very well defined..
We will launch again in a couple of month, maybe 6 to 8 weeks. If all goes well, we will be able to land the rocket. .. ohh.. although we will be happy if just gets to orbit of course. but hopefully it can come back and land as well.

Strange he can be so precise when you can't be that specific even in a nominal flow so far out, nevermind RTF. Anyway!
For RTF he actually said couple of month, 6-8 weeks.
