Scientists have used radar technology to shed new light on the subsurface of the moon. Researchers used the Miniature Radio Frequency (Mini-RF) instrument on NASA's Lunar Reconnaissance Orbiter (LRO) ...

Scientists have uncovered evidence of a massive underground lava tube hidden beneath the surface of Venus, revealing a new layer of the planet’s volcanic history. By reexamining radar data from NASA’s ...

Volcanic activity is not unique to Earth: traces of volcanic activity, such as lava tubes, have been found on Mars and the moon. Now, the University of Trento has demonstrated the existence of an ...

WEST LAFAYETTE, Ind. — To survive on other planets, water is, of course, critical. We need it to drink, sustain crops and even create rocket fuel. But on spaceflights, checked luggage is exorbitantly ...

With Europe’s Mars Advanced Radar for Subsurface and Ionospheric Sounding (Marsis) declared a success, planetary scientists around the world are eagerly anticipating other targets for the technology.

NASA’s Mars Reconnaissance Orbiter has extended the long-armed antenna of its radar, preparing the instrument to begin probing for underground layers of Mars. The orbiter’s Shallow Subsurface Radar, ...

ESA’s Mars Express radar sounder, MARSIS, has looked beneath the martian surface and opened up the third dimension for planetary exploration. The technique’s success is prompting scientists to think ...
