Destination Mercury by Andrew Liptak : Clarkesworld Magazine - Science Fiction & Fantasy


Science Fiction & Fantasy
 
by Andrew Liptak
There is no better example of how science fiction’s tendency to try and imagine a plausible future is like throwing a dart at a moving target than Larry Niven’s 1964 short story “The Coldest Place.” Up to that point, astronomers widely believed that the planet Mercury was tidally locked to the Sun: its rotation matched that of its orbit and as a result, only one side ever faced the Sun, meaning that its dark side would have been much cooler. Niven took that bit of knowledge and incorporated it into his story his first and sent it off to Frederik Pohl’s ....

10 Stunning New Ways To Visualize How The Earth Works


10 Stunning New Ways To Visualize How The Earth Works
Earth’s green-blue visage is awful nice, but we see it so often that we’re sick of it. Luckily, NASA and other space agencies are constantly dreaming up new ways to visualize the countless terrestrial processes we take for granted.
10Earth’s Plasmasphere
The plasmasphere is the inner portion of Earth’s magnetic field, and it’s fabulous. Recently, astronomers have found a constant flux of particles between the two electrically charged regions, forming a terrestrial version of the solar wind.
As solar UV radiation strikes the atmosphere, it kicks off a gigantic ionic rave. Tiny electrons are whipped up and ionize other particles, creating a magnetic stew high above Earth’s surface. The flow is somewhat modest in cosmic terms. It releases only about 1 kilogram (2.2 lb) of charged material into the outer magnetosphere per second. Daily, this adds up to 90 tons of plasma discharge, and this flowing electr ....

A Field Guide to the Magnetic Solar System


A Field Guide to the Magnetic Solar System
Not all planets move the needle. But whatever planet you take a magnetic compass to, it’s sure to point out clues to secrets underfoot.

Congratulations! With the IP9, the new interplanetary model in Eos’s signature line of magnetic compasses, you’ve chosen a travel companion that will serve you as best it can on the many GPS-challenged bodies of our solar system be your plans a hike on Mercury, a ride on Mars, or a glide over Neptune.
Before you start using your compass, please note that your warranty is voided when you drop your IP9 onto a hard surface or into a high-pressure or high-temperature environment, or store it unshielded from magnetic fields during extended periods of interplanetary travel. ....
