SpaceX
made their second attempt today, Feb 25, to launch the SES-9
satellite into orbit. The launch was scheduled for 6:46 pm EST (3:46
pm PST) on launch complex 40 at Cape Canaveral, Florida. At T –
1:41 the countdown was halted a few seconds before the mission was
scrubbed. This was the second time in two days that the mission had
to be postponed due to propellant reasons. There is no date set to
make a third attempt to carryout the mission.
The
commercial space company said Wednesday's scrub was "out of an
abundance of caution," but that the Falcon 9 rocket "remains
healthy."
"Out
of an abundance of caution, the team opted to hold launch for today
to ensure liquid oxygen temperatures are as cold as possible in an
effort to maximize performance of the vehicle."
When
SpaceX is finally able to carryout the deployment of the SES-9
communication satellite it will be placed in a geostationary orbit
approximately 36.000 kilometers over the Indian Ocean. Once in
position the satellite will provide satellite-enabled communications
to broadcasters, Internet service providers, marine traffic, and
fixed networks. The SES-9 will join some 50 other geostationary
satellites that provide similar communications worldwide.
A
secondary part of the mission will again see SpaceX attempt to land
the first stage of the Falcon 9 rocket on a drone barge. SpaceX has
already made one successful attempt at landing their rocket back in
December. Since that successful land they have also had an
unsuccessful attempt in a January when of legs on the rocket buckled.
"One
of the limiting factors to a more-robust space program is the cost of
getting payloads into orbit," said Rob Salonen of Florida
Institute of Technology. "If SpaceX can make it less expensive
to do that, it lowers the cost of that orbit."
