Gravity-sensing NASA probe may reveal exoplanet interiors with 100x precision

SMRTR summary

NASA's proposed Gravity Imaging Radio Observer (GIRO) could revolutionize exoplanet study. This compact, low-cost probe uses gravity signals and radio waves to map planet interiors with 10-100 times better accuracy than traditional methods. GIRO could reveal features like metallic cores or volcanic activity on distant worlds, potentially transforming our understanding of alien planets.
