Here today, gone tomorrow; a bright layer of frost lining a crater wall is vanquished by the springtime sun -- and seen by a NASA Mars satellite high overhead.

Earlier this year, NASA's LADEE moon orbiter was intentionally crashed into the lunar surface after completing its mission. Now, another moon orbiter has spotted LADEE's final resting place for the first time. Continue reading →
Through the analysis of isotopes trapped inside ancient quartz crystals, geochemists have realized that the Earth-shattering cosmic impact that laid waste to our young Earth and formed the moon happened 60 million years earlier than thought.
Trying to understand the ancient climate of our own planet is hard enough, but to understand Mars' climatic history, planetary scientists have had to turn to a rather inventive method of climate forensics. Continue reading →
