If you're going to Mars you'd best take along a jar of anti-aging cream because while you're there you're going to age faster than on Earth thanks to the Theory of Relativity. It's only 477 millionths of a second per day, but that tends to add up.

According to NASA, Saturn's moon Titan may be the most fantastically large slushie of all time. Based on a reexamination of data from the Cassini probe collected in 2012, the moon's long-suspected global ocean may actually be a slurry of ice and rock.

One of the big challenges in building a space rover is ensuring it doesn't break down out there. Aerospace engineers have designed a flexible wheel for rovers that doesn't require an air-filled tube, can change its size, and can take a real beating.

As it heads out of the solar system never to return, the deep space probe Voyager 1 is headed for yet another cosmic milestone. In late 2026, it will become the first spacecraft to travel so far that a radio signal from Earth takes 24 hours, or one light day, to reach it.
