KENNEDY SPACE CENTER,
FL –  A technical glitch in the final
seconds of the countdown leading up to the first launch of the newly improved Falcon
9 Block 5 booster built by Elon Musk’s SpaceX aborted Thursday’s planned May 10
blastoff from the Florida Space Coast with Bangabandhu-1; the the 1st ever
geostationary communications satellite for the nation of Bangladesh. 

Launch has been
rescheduled to Friday afternoon, May 11.



The launch was unexpectedly aborted
automatically at T Minus 45 seconds due to a
“standard ground
system auto abort” SpaceX said later after the 22-story tall rocket had been fully fueled and was vigorously
venting vaporized liquid oxygen propellant in its gaseous form from the second
stage.



Liftoff from historic
seaside Launch Complex 39A at NASA’s Kennedy Space Center (KSC) in Florida has
been reset to Friday afternoon, May 11, after SpaceX engineers reviewed the
telemetry.


“Standing down today due to a standard ground
system auto abort at T-1 min,” SpaceX tweeted.

“Rocket and payload are in good health—teams
are working towards tomorrow’s backup launch opportunity at 4:14 p.m. EDT, or
20:14 UTC.

The May 11 launch window again extends
slightly over two hours; opening at 4:14 p.m. EDT
(2014 GMT) and closing at 6:21 p.m. EDT (2221
GMT).  












This newest and last
major upgrade to the Falcon 9 is dubbed the Block 5 version. The rocket on pad
39A is the first built Block 5 rocket.


At a prelaunch media
telecon SpaceX CEO Elon Musk says numerous improvements built onto the Block 5
Falcon 9 will significantly increase the reliability and reusability of the
Falcon 9 including faster turnaround with less maintenance and fewer
refurbishments.

Musk expects each Block 5 rocket to launch 10 times before requiring
any appreciable maintenance or refurbishments.

The weather outlook for Friday has improved and is currently
favorable. The official forecast issued last night by the U.S. Air Force’s 45th
Weather Squadron indicates a 70% chance of favorable weather conditions at
launch time, compared to 60% earlier.





The primary concern is for the Thick Cloud Layer Rule.

In case of a 24 hour delay, the forecast drops to a 60% chance of
favorable weather conditions at launch time. The primary concern remains for
the Thick Cloud Layer Rule and Cumulus Cloud Rule.
