2021年7月22日 · Before NASA’s InSight spacecraft touched down on Mars in 2018, the rovers and orbiters studying the Red Planet concentrated on its surface. The stationary lander’s seismometer has changed that, revealing details about the planet’s deep interior for the first time.

2021年7月23日 · Direct seismic observations on Mars represent a major leap forward in planetary seismology. The size of the martian core, the crustal layering, and the thick lithosphere provide important insights into the thermal and dynamic evolution of Mars.

2021年7月23日 · An immobile probe sitting like a squat turtle on the surface of Mars has finally delivered a comprehensive picture of the red planet's internal structure. The Mars InSight lander measured around 733 marsquakes, and used information on 35 of them, to form a picture of the crust, mantle, and core.

2024年4月17日 · InSight studied the deep interior of Mars and was designed to take the planet's vital signs: its pulse, temperature, and reflexes. InSight was the first mission to give Mars a thorough checkup since the planet formed 4.5 billion years ago.

2005年5月20日 · For the past decade, space missions to Mars have provided important constraints on the physics and chemistry of its interior, although these missions were primarily designed to map and understand surface or near-surface features of the planet.

The mystery of Mars’ interior. Internal structure of Mars (© NASA). Unlike our own planet, whose internal structure has been well defined, our knowledge of the interior of other planets in the solar system is as yet very limited. Geophysicists gaze at them longingly, dreaming of shedding light on their internal structure just as they have ...

2021年7月22日 · Like a bruised peach sliced apart to reveal an enormous yellow pit, Mars shares its inner mysteries in the first-ever map of an alien planet's interior — released as part of three new studies...

2021年7月23日 · More than two years of seismic monitoring has resulted in the very first model of the internal structure of Mars, right down to the core. Mars thus joins the Earth and the Moon in the select club of terrestrial planets and moons whose …

2018年2月21日 · What's inside Mars? We know a lot about what's inside Earth. But at Mars, we've only just scratched the surface. To learn how Mars formed, we have to study its deep interior. NASA's InSight lander was designed to do just that by taking the planet's "vital signs": Listening for its "pulse" or seismic activity, including any "Mars quakes";

2021年7月22日 · Since early 2019, the seismometer of NASA's InSight lander has been collecting data crucial to understand Mars's internal structure. Thanks to InSight, scientists have determined the size of...
