by If the atmosphere of Venus was at any point thin and similar to Earth’s, then ancient asteroid impacts transferred potentially detectable amounts of Venusian surface material to the Moon, according to new research from Yale University.
Recovery and isotopic analyses of Venusian surface samples from the lunar surface would determine with high confidence both whether and when Venus harbored liquid oceans and/or a lower-mass atmosphere.
“Asteroids and comets slamming into Venus may have dislodged as many as 10 billion rocks and sent them into an orbit that intersected with Earth and Earth’s Moon,” said Yale University researchers Samuel Cabot and Gregory Laughlin.
“Some of these rocks will eventually land on the Moon as Venusian meteorites,” Cabot added.
