I'm used to reading excellent articles by Emily, but this one I found to be of truly extraordinary interest:

If I recall correctly from my conversation with them, they re-run the chilling routine every other day. So every other day you reset the clock on the frozen hydrogen. Which means that if you're the science team you really want the spacecraft to launch on that first rather than second day. I would imagine that with the weekend's delay, Monday will be "day 1" of that cycle.
Also, I just remembered that the chilling routine involves a team of poor guys whose sole job is to run those tanks of liquid helium up the tower to the top of the rocket, where the spacecraft is, remove the old tank, hook up the new tank, run the old tank down to the bottom of the tower, and repeat. -------------------- My website - My Patreon - @elakdawalla on Twitter - Please support unmannedspaceflight.com by donating here.
