NASA’s Perseverance Rover Captures New Sounds on Mars

APL’s Ralph Lorenz is part of an international science team performing the first analysis of acoustics on Mars, releasing a new study that details how fast sound travels through the Red Planet’s extremely thin, mostly carbon-dioxide atmosphere and how Mars might sound to human ears.

Comet 67P’s Abundant Oxygen More of an Illusion, New Study Suggests

Seven years ago, scientists made the surprising discovery of oxygen coming from comet 67P/Churyumov-Gerasimenko, throwing into question much of what they thought they knew about the early solar system. But a new study led by Johns Hopkins APL researchers reveals new details that suggest not everything about that discovery is as it seems.

New Analysis Points to Comets as Source of Near-Surface Ices at the Moon’s South Pole

A new analysis examining elemental data from a NASA mission more than a decade ago pins down comets as the source of water ice and volatile elements near the Moon’s South Pole. The finding sheds light on another piece of the Earth-Moon system’s history and underscores the use of the Moon’s ices for revealing that story.

Large-Scale Liquid Water Existed on Mars Much Longer Than Suspected

An analysis of large salt deposits on Mars, led by Johns Hopkins APL researcher Ellen Leask, indicates that ponds of liquid water existed on the red planet for about a billion years longer than previously believed.
