Stratospheric Observatory for Infrared Astronomy (SOFIA) should proceed
to completion, with science flights starting as early as 2008. . . .

material sits on the inner edge of the tenuous G ring, fattening one
segment of it into a feature that planetary scientists call a ring arc
- the first ever seen around Saturn. . . .
