Since its launch, a total of 614 hatches
have been installed through the U.
Although these escape hatches are numerous, they're extremely narrow, making it difficult to explain how so many asteroid fragments end up pelting the inner planets.
Early last year, two researchers suggested that a subtle nongravitational effect, which is so tiny it had often been overlooked, helps usher toward these zones asteroids that originate far from the escape hatches.
Early-spring Blue-winged Olive (Baetis, BWO) and midge hatches
are often intense and offer the best dry-fly fishing of the year.
Atlantis has five hatches
and ``we want to make sure all of them are operable,'' shuttle program manager Tommy Holloway said.
for example, has an extensive inspection facility where mechanical components, ladders, walkways, caps, compartment linings, hatches
and valves are examined and, if necessary, repaired.
But come May and June, when the giant salmonfly and golden stonefly hatches
are in full bloom, dry-fly specialists from around the region are drawn like magnets to try their hands at the crimson, football-shaped trout so famous that the mascot of Wasco County High School here is the Redsides.
If you don't, the hatches
aren't locked shut and they will leak.
