O Spirit, whom the Father sent
To spread abroad the firmament;
O Wind of heaven, by thy might,
Save all who dare the eagle's flight.
And keep them by the watchful care
From every peril in the air.
from Jerry Pournelle

Almighty Ruler of the all,
Whose Power extends to great and small,
Who guides the stars with steadfast law,
Whose least creation fills with awe,
O grant thy mercy and thy grace,
To those who venture into space.
- Robert A. Heinlein
