If the Atlantis launch happens on September 7th here are some other past history for this date which may give us some insight:
 

Events
1251 BC - A solar eclipse on this date might mark the birth of legendary Heracles at Thebes, Greece.
Heracles may have been a Nephilim, part god (little “g”)/part man.  Offspring from the demons leaving their places and taking human wives…

70 - A Roman army under General Titus occupies and plunders Jerusalem.

1191 - Third Crusade: Battle of Arsuf - Richard I of England defeats Saladin at Arsuf. 

1988 - Abdul Ahad Mohmand, the first Afghan in space, returns aboard the Soviet spacecraft Soyuz TM-5 after 9 days on the Mir space station
