First audio recorded on Mars reveals two speeds of sound

The first audio recordings on Mars reveal a quiet planet with occasional gusts of wind where two different speeds of sound would have a strange delayed effect on hearing, scientists said Friday.

Printing bricks from moondust using the sun's heat

Bricks have been 3-D printed out of simulated moondust using concentrated sunlight – proving in principle that future lunar colonists could one day use the same approach to build settlements on the moon.
