The scientific value of determining the radius to a landed payload is discussed and a method for measuring the radius is suggested. By measuring the gravity field strength at the surface of the planet to an accuracy of 1 part in 104, it is possible to infer the radius to 1 km....
What is the radius of Mars in km? What is the angular size of Mars? What is the circumference of the planet Mercury? What is the circumference and diameter of Earth? What is the angular size of the Sun from mars? What is the size of the planet Mars? What is the distance from Mars...
Answer to: Mars has a radius of about 0.53 earth radius and a mass of only 0.11 earth mass. (a) Estimate the acceleration due to gravity on Mars...

The formation and differentiation of the crust of Mars in the first tens of millions of years after its accretion can only be deciphered from incredibly limited records. The martian breccia NWA 7034 and its paired stones is one of them. This meteorite co
The first step is to compare the AIMD-predicted P-wave velocity and density profiles for pure liquid Fe with those determined using the InSight seismic data2(Fig.1). The comparison shows that at Mars’s CMB, that is, the 1,780–1,840 km core radius determined by ref.2, the density...
The formula describes a near-parabolic dependence of the partition coefficient Di on the radius ri of the corresponding site (e.g., M1 and M2 in clinopyroxene). This relation can be used to construct so-called Onuma diagrams using linear least squares regression on E, D0, and r0 for iso...
In 1672, Giovanni Cassini used a method involving parallax, or angular difference, to find the distance to Mars and, at the same time, figured out the distance to the sun. He sent a colleague, Jean Richer, to Cayenne, French Guiana (located just northwest of the modern-day Guiana Space ...
