Ken Kremer — SpaceUpClose.com — 4 June 2018
CAPE CANAVERAL
AIR FORCE STATION, FL – A spectacular midnight launch lit up Florida Space
Coast skies Monday, June 4, as the massive six ton SES-12 high powered commercial
telecommunications satellite that will provide ever better TV, internet and
more to ground, airplane and cruise ship services for millions of customers – soared
to orbit on a recycled SpaceX Falcon 9 rocket.
SES-12 will serve
over 18 million customers across the globe all the way from the Middle East to
the vast Asia-Pacific region for Luxembourg-based operator SES.

Today’s launch comes after a four day delay announced last
Thursday when SpaceX said
engineers needed to run “run additional tests” on the workhorse Falcon 9 vehicles
second stage to verify its readiness to launch.
This Falcon 9
rocket was comprised of a unique combination of old and new involving a
‘Flight-Proven’ Block 4 first stage and a new and improved Block 5 upper stage.
The first stage is expendable and was not recovered.

The path to
launch was cleared last week when SpaceX engineers conducted a successful hold
down static fire test of the rocket at the pad, minus the payload, wherein the
two stages were fueled with propellants completing a full countdown simulation.
