CAPE CANAVERAL AIR FORCE STATION, FL- A SpaceX Falcon 9 rocket was raised at pad 40 this evening in anticipation of the Tuesday morning,
Dec. 18, launch of the inaugural satellite of the US Air Force’s most power Global Positioning System (GPS) III satellite series
ever built – namely GPS III SV01 – from the Florida Space Coast.
Rumors are rife that Vice President Mike Pence has already flown in from
Washington, D.C. on a special trip to witness the launch first hand.
The 23 story tall Falcon 9 stood poised magnificently erect at night for
liftoff just 12 hours from now as myself and our media gaggle were setting up
our cameras at Launch Complex 40 tonight, Monday, Dec. 17- backdropped against
the blackness of the evening sky.
of the next and last SpaceX Falcon 9 of 2018 carrying the modernized and
advanced GPS III SV01 satellite for the Air Force is slated
for blastoff Tuesday, Dec. 18 at 9:11 a.m. EST, 14:11 GMT,
Launch Complex-40 on Cape Canaveral Air Force Station, FL.

Space UpClose photos taken at pad 40 this evening.
All is well with the
rocket and the weather!
and GPS III SV01 are vertical on Pad 40 in Florida. Vehicle and weather are go
for tomorrow’s 26-minute launch window, which opens at 9:11 a.m. EST, 14:11 UTC,”
SpaceX tweeted this evening.
The weather outlook remains quite favorable – currently
forecast as 90% GO !!
The Falcon 9 launch window lasts for 26 minutes
and extends from 9:11 a.m. to 9:37 a.m. EST Dec. 18.
In case of a delay for any reason, a backup
launch opportunity exists on Wednesday, Dec. 19 at 9:07 a.m. ET (1407 GMT).
You can watch the launch on a SpaceX dedicated
webcast that starts about 15 minutes prior to the opening of the nominal
launch window at:
version on an expendable mission where the first stage booster will not be
recovered. There are no grid fins or
landing legs installed on the 15 story tall first stage.
This is the first Block 5 model that will launch
in an expendable configuration and not be soft landed either by land or by sea.
The Air Force wants every drop of fuel available
to hurl the GPS III SV01 satellite to the most efficient orbit and maximize the
amount of on-board fuel available and minimize the satellites need to utilize
the fuel reserves for orbit raising maneuvers.
The satellite will be deployed to medium Earth
orbit approximately 1 hour and 56 minutes after liftoff.
The GPS III satellites has a wet weight of 9700
pounds (4,400 kilograms) and is the size of an SUV.
From the SpaceX Press Kit:
The United States’ Global Positioning System
delivers positioning, navigation, and timing services supporting vital U.S. and
allied operations worldwide, and underpins critical financial, transportation,
and agricultural infrastructure that billions of users have come to depend on
Artists concept of Lockheed Martin GPS III SV01 in orbit
The United States Air Force’s first GPS III
satellite will augment the current constellation of 31 operational GPS
satellites. This newest generation of GPS satellites is designed and built to
deliver positioning, navigation, and timing information with three times better
accuracy, and up to eight times improved antijamming capability. GPS is used by
over four billion users and supports critical missions worldwide.
GPS is a National Security Space (NSS) mission,
critical to national defense. In April 2016, SpaceX was awarded its first NSS
mission, GPS III SV01. SpaceX currently has an additional four GPS III missions
on contract, all of which will be launched on Falcon 9.
