The world is sitting at the intersection of science fiction and science fact, in large part because of sci-fi devotees.

“People who are actively aware of what could be possible are psychologically more flexible than people who aren’t,” psychologist Michael Mahon told “St. Louis on the Air” host Don Marsh. Mahon was trained as a clinical psychologist but now works as a licensed professional counselor.

Maggie Duckworth is an electrical engineer and costume designer. She’s also the only St. Louis-area resident who’s still in the running for a one-way ticket to Mars.

Duckworth is a finalist for the Mars One mission to build a human colony on the Red Planet. Mars One is a Dutch nonprofit organization that plans to send humans to Mars by 2024. It will award 24 one-way tickets and Duckworth has made it through three rounds of cuts.

There are something on the order of 12,000 to 15,000 pieces of space debris larger than a softball in size orbiting the Earth.

Space debris probably isn’t at the top of your list of day-to-day concerns.

The junk we’ve left floating around in space includes everything from spent rocket stages and old satellites, to nuts and bolts ― even tiny flecks of paint.

And it’s constantly colliding with satellites and anything else in what's known as “low Earth orbit,” including the International Space Station.

Here's a view you don't get every day:

It was tweeted in January by the commander of the International Space Station, Canadian astronaut Chris Hadfield. He's been making it his job to not only lead Expedition 35 of the ISS but also amass a dazzling collection of images of the Earth from space.

The group of scientists working with NASA's Curiosity rover made a big announcement during a press conference today: "We have found a habitable environment that is so benign" if there was water there, "you be able to drink it," John P. Grotzinger, professor of geology at Caltech, said summing up the rover's latest findings.

That is, at one point Mars had the right conditions to support living microbes.

The images of this past week's heavy snowfall in Missouri and across the Midwest are familiar and chaotic - cars in ditches, closed airports and overall gridlock of infrastructure.

Today's NASA "Image of the Day" provides a decidedly more peaceful look at the storm's effects, from space.

Here's how NASA describes this image and the technology they used to capture it:

Scientists have discovered a world much fancier than our homely, little Earth.

New research that will published in the journal Astrophysical Journal Letters details a planet that is eight times heavier than Earth and with twice its radius. But instead of being covered in water and granite, it is encrusted in graphite and diamond.

NASA's Curiosity rover has found definitive proof that water once ran across the surface of Mars, the agency announced today. NASA scientists say new photos from the rover show rocks that were smoothed and rounded by water. The rocks are in a large canyon and nearby channels that were cut by flowing water, making up an alluvial fan.

"You had water transporting these gravels to the downslope of the fan," NASA researchers say. The gravel then formed into a conglomerate rock, which was in turn likely covered before being exposed again.

The Voyager 1 spacecraft's 35th anniversary is proving to be unexpectedly exciting, as scientists gathered this week to examine new hints that the spacecraft is on the verge of leaving our solar system.

Voyager 1 is now more than 11 billion miles away from Earth. It blasted off in September 1977, on a mission to Jupiter and Saturn. But it also carried a Golden Record filled with music and the sounds of our planet, in case it encountered intelligent life as it moved out toward the stars.

Before we run through the news of the day, let's pause for something spectactular: a new video from NASA's Solar Dynamics Observatory. It shows a "massive filament" eruption on the sun that occurred last Friday. As Britain's The Register says, it is "mind-bogglingly gorgeous."
