Radar data reveals hidden layers beneath the Moon’s south pole, helping scientists map subsurface structures and support future Artemis missions.

NASA's Perseverance landed on Mars in February 2021 and has been gathering data on the planet's geology and climate and searching for signs of ancient life. The rover's subsurface radar experiment has ...

A research team from the University of Trento has found the first direct radar evidence of a lava tube on Venus, identifying a subsurface conduit roughly a kilometer wide beneath the shield volcano ...

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 ...

Venus skylight in the Nyx Mons region reveals a subsurface cave, hypothesized to be a lava tube. The feature was identified through analysis of radar images acquired by the SAR instrument aboard the ...

For the first time, scientists have strong evidence that a huge volcanic cave lies beneath the surface of Venus. By reanalyzing radar images from NASA’s Magellan mission, a team from University of ...
