Author Correction: Layered subsurface in Utopia Basin of Mars revealed by Zhurong rover radar

MarsMars, often called the "Red Planet," is the fourth planet from the Sun and the most Earth-like planet in our solar system. Its reddish color comes from iron oxide, or rust, that coats its surface. Mars is home to the largest volcano in the solar system, Olympus Mons, and deep valleys such as Valles Marineris. Scientists study the planet to understand its history, search for signs of water, and explore the potential for future human missions. Scientists can better predict how planetary...

Deposition By GroundwaterAs groundwater moves through underground spaces and rock layers, it can carry dissolved minerals with it. When the water reaches open spaces like caves or slows down, it begins to deposit those minerals. Over time, this process builds up formations such as stalactites, which hang from the ceiling, and stalagmites, which rise from the ground. These structures grow slowly, sometimes taking thousands of years to form. Deposition by groundwater can also leave behind mineral...

Topography involves measuring and mapping land elevations, natural features, and artificial structures to create accurate representations of the terrain. Topographic surveying relies on traditional and modern methods, each with distinct advantages and limitations.Traditional Surveying Methods:Transit stadia surveys and plane table surveys were widely used traditional surveying methods. These techniques relied on instruments like theodolites and stadia rods for measuring distances and angles,...

Erosion By GroundwaterGroundwater is water that moves slowly through spaces in soil and rock beneath Earth’s surface. Over time, groundwater can cause erosion by dissolving certain types of rock, especially limestone. This type of erosion happens underground and leads to the formation of caves, sinkholes, and underground streams. When acidic groundwater moves through rock layers, it gradually widens cracks and creates large openings. As erosion continues, the roof of a cave may collapse,...

In an experiment conducted during a Mars mission, a rover propels a projectile with an initial velocity, and the projectile rebounds after colliding with the Martian surface. To ascertain the maximum height attained by the projectile after this collision, the known restitution coefficient and acceleration due to gravity are employed.
By designating the launch point as the origin and utilizing kinematic equations, the vertical component of the projectile's velocity at the point of impact is...

During leveling, the Earth's curvature and atmospheric refraction introduce deviations in the line of sight from a true horizontal reference. When the line of sight is leveled, it remains perpendicular to the plumb line only at a single point. Beyond this, it deviates due to the Earth’s curvature, represented by the correction C. For a sight distance D, the deviation can be derived using the relationship:This relationship shows that the deviation increases quadratically with distance.
