Much of Mars’s surface is covered by fine-grained materials that hide the bedrock. The above bedrock is mostly exposed and it is in these areas that micrometeorites likely to accumulate.

It's established Mars was once a planet with surface-level water. So with multiple MARS missions starting next year, the key to seeking out martian life may instead lie in the contents of its 'dust'.
The Sun is currently middle-aged, having celebrated its 4,568,000,000th birthday at some point in the last million years.
In five or seven billion years time, the Sun's life will come to an end. And it will be really spectacular - if you're watching from far enough away.
Specialized chamber to study dusty plasma in the lab.
The vast majority of matter in the universe is plasma: electrically charged gas. Scientists are untangling how dust interacts with plasma both in space and experimentally closer to home.
New Horizons continues to help unravel the icy dwarf planet’s secrets.

After last summer's Pluto flyby, the New Horizons spacecraft started sending data back to Earth – at 2 kilobits per second. Here's some of what scientists have learned so far from that rich, slow cache.
The tail of a comet is the release of interplanetary dust.
Cosmic dust may have jump-started life on Earth as well as on distant planets.
Dust that didn’t become a star.
In 1999, US space agency NASA launched the Stardust spaceship with what seemed then to be extraordinary aims. The first task…
Fallen from the sky, in your lap.
When you clean your house you are probably vacuuming up space dust. Not kidding. It is the same dust that was once part of comets and asteroids. You see that dust in the faint glow it helps create before…
