Benchmarks: January 23, 1960: Humans reach the deepest point on Earth

More than 9,000 meters underwater, a window buckles, sending a spider web of cracks across the glass. The entire submersible shakes, but no water rushes into the Trieste. Out of vocal contact with the main ship on the surface above them, Swiss oceanographer and engineer Jacques Piccard and U.S. Navy Lt. Don Walsh decide to continue their descent despite the new danger. After all, at more than nine kilometers below the sea surface, the explorers were too close to their goal to turn around. They were only 2,000 meters away from the deepest spot on Earth: Challenger Deep. On Jan. 23, 1960, they reached that fabled point 10,916 meters below the surface of the Pacific Ocean.

Benchmarks: October 13, 1947: A disaster with Project Cirrus

Two days after clipping Cuba and Florida, a hurricane was drifting out into the Atlantic. All predictions had it remaining at sea without further landfall, making it the perfect test subject for the newly minted Project Cirrus, a U.S. government- backed project bent on discovering a way to disable deadly hurricanes. The researchers planned to seed the hurricane’s clouds with dry ice, hoping that the ice would interact with the clouds and disrupt the cyclone’s internal structure, thus weakening it. So on Oct. 13, 1947, a plane flew over the storm and dumped 80 kilograms of dry ice into the storm’s swirling clouds.

From science to science fiction

Project Cirrus may have flopped in the meteorology world, but its research left an indelible impression on the literary world.

Blogging on EARTH: Climate change threatens Virginia's vacation spots

Each year, millions of visitors flock to Virginia’s natural wonders, such as Shenandoah National Park, and to historical landmarks, like Jamestown, one of America’s earliest colonies.
