All the Rivers & Streams in the U.S. Shown in Rainbow Colors

A data visualization to behold



A beautifully rendered multi-color map. Created by Hungarian geographer and map-designer Robert Szucs, using open-source QGIS software, the high resolution map above shows:

all the permanent and temporary streams and rivers of the contiguous 48 states in beautiful rainbow colours, divided into catchment areas. It shows Strahler Stream Order Classification. The higher the stream order, the thicker the line.

When you look at the map, you'll see, as The Washington Post observes,

 "Every river in a color drains to the same river, which then drains into the ocean. The giant basin in the middle of the country is the Mississippi River basin. Major rivers like the Ohio and the Missouri drain into the behemoth."

Pretty cool.

Blue-Green and Red Clouds on Sunday Night

NASA Rocket Launch Will Create Blue-Green and Red Clouds on Sunday

NASA

On June 11, East Coast skywatchers may be in for a lovely show Sunday night, as NASA launches a sounding rocket and brightly colored vapor clouds into the night.

The (dog-inspired?) Terrier-Improved Malemute rocket is an information-gathering craft laden with instruments to capture information about our atmosphere and ionosphere. Its path will follow a sharp U-shaped trajectory, launching from NASA’s Wallops Flight Facility in Wallops Island, Virginia, soaring miles into the sky, peaking, then falling back to Earth and plunging into the Atlantic Ocean.

The launch is scheduled to occur between 9:04 and 9:19 p.m. EDT. Experts estimate that the flight will take about eight minutes from start to finish. Approximately four or five minutes after the rocket takes off, NASA will deploy 10 soda can–sized canisters full of reactive chemicals. The cans will burst 96 to 124 miles in the air, producing enormous, vibrant blooms of harmless red and blue-green clouds formed by the interaction of barium, strontium, and cupric-oxide. (These are commonly found in fireworks.) If the weather cooperates, these vapor tracers should be visible from New York to North Carolina and westward into Virginia.

Scientists will track the movement and dissipation of the clouds to understand how particles and air are flowing through the sky above us. Deploying the vapor tracers at a distance from the rocket should help provide an even fuller picture of just what’s going on up there.

You can catch it via Ustream or on the project’s Facebook and Twitter pages.
