Scientists discovered a molten silicate layer beneath the Martian mantle using InSight mission data, contradicting earlier assumptions about the planet's internal structure. This new finding suggests that Mars experienced an early magma ocean stage and provides insights into the formation of its core.
New research on asteroid samples from Ryugu reveals similarities to Ivuna-like carbonaceous chondrites, providing a better understanding of the early solar system. The study also sheds light on the accretion of volatiles during planetary formation and finds that Ryugu-like material accounts for ~5-6% of Earth's mass.
Researchers used seismic data and orbital observations to refine knowledge of Mars' planetary interior. The studies provide new constraints that validate and refine models of the planet's internal structure and dynamics of major impacts.
The InSight mission has successfully mapped the internal structure of Mars using seismic waves detected by the SEIS instrument. The analysis revealed an estimate of the core size, crust thickness and mantle structure, providing valuable information on the planet's formation and thermal evolution.
