CAPE CANAVERAL AIR FORCE STATION, FL – Todays launch of GovSat-1 on a reused
SpaceX Falcon 9 rocket was scrubbed when the launch team detected a faulty
sensor in the vehicles second stage about 90 minutes prior to Tuesday’s targeted
launch time.

GovSat-1 was developed as a joint venture in a public-private
partnership between the Government of Luxembourg and satellite operator SES. 

The faulty sensor is being replaced and forced a 24 hour postponement to
Wednesday, Jan. 31.










The SpaceX launch team has rescheduled the launch to occur 1 day later
within the same launch window.



“Standing
down for today,” SpaceX tweeted.



“Team
is going to replace a second stage sensor. Next available launch opportunity is
tomorrow, January 31.”



Liftoff of the recycled single stick Falcon 9 carrying GovSat-1 is now scheduled for Wednesday, Jan.
31, 2018 at
4:25 p.m. EST (2125
GMT) from seaside
Space Launch Complex-40
(SLC-40) on Cape Canaveral Air Force Station.



Extremely brisk ground winds
and upper altitude winds had also threated to delay the launch. But in the end it
came down to a sensor glitch.  

The weather outlook is
significantly improved for Wednesday with a 90% chance of acceptable conditions
vs. only 40% acceptable on Tuesday.

The rocket will be lowered horizontal at pad 40 so technicians can swap
out the bad port for a new one. After checkout it will then be raised again to
vertical launch position



The two stage 229-foot-tall (70-meter-tall) SpaceX Falcon 9
rocket will deliver GovSat-1/SES-16 to a geosynchronous transfer orbit for
GovSat – the SES and Luxembourg government joint venture.


GovSat-1, also known as SES-16, is the first satellite of
GovSat. It is uniquely
designed for exclusive use by governments and
institutions – including m
ilitary, humanitarian and maritime users.

flexible payload featuring advanced encryption and anti-jamming capabilities.



The over 4.5 ton GovSat-1/SES-16 communications satellite launching
Tuesday is a 50:50 joint venture between the Government of Luxembourg and the commercial firm SES, the
worlds leading satellite operator.

You
can watch the launch live on a SpaceX dedicated webcast starting about 15
minutes prior to the 4:25
p.m. EDT (2025
GMT)
liftoff time.

The GovSat-1
launch window at pad 40 extends for a little over two full hours. The window
opens at 4:25
p.m. EST (2125 GMT) and extends
until closing at 6:46 p.m. EST, or 2346 GMT.

GovSat-1 will be located
at the 21.5 degrees East orbital slot. 

It will serve Europe,
the Middle East and Africa, including substantial maritime coverage over the
Mediterranean and Baltic seas, and the Atlantic and Indian Oceans.





In contrast to most recent launches, this ‘flight-proven’ Falcon
9 will not be recovered.

However it is equipped with a quarteet of grid fins and
landing legs and will guided to carry out the descent recovery sequence and make
a soft ocean landing – minus the drone ship.

The recycled first stage for the GovSat-1 mission was previously
used to launch the NROL-76 spy satellite on a classified mission for the National
Reconnaissance Office  (NRO) from LC-39A
in May 2017.
