Well it's probably time. The countdown clock didn't have enough
digits for counting down from the potential decades between manned
SLS missions.
Plus the new "clock" can display fancy graphics. Perhaps it can
distract the press from the dismally low launch rate and extremely high
launch costs.
Besides we don't have countdown clocks for commercial airline,
train or bus departures. Looking forward to the day when the same
can be said for space travel.
There are most certainly displays showing departure times. These are
arguably less "exciting" than a countdown clock that is "accurate" to
the second, but they provide essentially the same information.
