09/15/2016 – Ephemeris – SpaceX has an explosion in its Falcon 9 second stage

September 15, 2016

Ephemeris for Thursday, September 15th.  The Sun will rise at 7:22.  It’ll be up for 12 hours and 30 minutes, setting at 7:52.  The Moon, 1 day before full, will set at 7:01 tomorrow morning.

The rocket company SpaceX had one of its Falcon 9 Rockets explode as it was being fueled for a test firing to check out its booster engines on September first.  The second stage, which was being loaded with fuel exploded.  Even if a tank had been ruptured, there should be no ignition source to cause the explosion.  Unfortunately the satellite, AMOS-6 a communications satellite destined for geosynchronous orbit, was already mounted on the rocket, and can be seen falling off the rocket just after the explosion.  This is the second failure of a Falcon 9.  In June of last year a helium tank inside the liquid oxygen tank in the second stage broke loose and ruptured the tank, while still being boosted by the first stage.  It took a few seconds after the rupture before the fuel ignited causing the explosion that ended the mission.  SpaceX has issued a request for videos or anything that might shed light on the latter accident.

Times are for the Traverse City/Interlochen area of Michigan. They may be different for your location.
