After its first year in orbit around Mercury, NASA's MESSENGER spacecraft has yielded data on the planet's structure: the iron core is larger than previously thought and, unusually, is encased in a relatively thin shell of iron sulphide. Maria Zuber at the Massachusetts Institute of Technology...
Explain what will happen to a drop of water placed on the surface of clean mercury.Question:Explain what will happen to a drop of water placed on the surface of clean mercury.ViscosityThe resistance produces in the movement of liquid is called viscosity. Newton's laws ...
The thin atmosphere allows most cosmic rays to bombard the planet, stripping neutrons from elements lying on the surface. MESSENGER studied material kicked up and found traces of potassium and silicon, suggesting that the elements lie on the planet's surface. The crust of Mercury is likely very...
General relativity and changes in Mercury's orbit The orbit ofMercuryis shifting very gradually over time due to the curvature of space-time around the massive sun,according to NASA. As the closest planet to the sun, Mercury’s perihelion (the point along its orbit that it’s closest to th...
to bone and helps with voluntary movement; smooth, which is found inside organs and helps to move substances through them; and cardiac, which is found in the heart.The body's largest muscleby mass is the gluteus maximus, but the two latissimus dorsi are the largest in terms of surface ...
By "logic" he means "verbal reasoning", and he's reasoning from imprecise jargon. The actual logic used is the maths, into which we can plug the output of some sensors and get the predicted output of some sensors at another time. For example, the position of Mercury on the night sky...
There has been some activity on the east coast, and there is a lot of need for activity in the Midwest; however, there are "too many sellers and not enough buyers," he added. In addition to difficulty dealing with regulatory overhead, boards are "tired of fighting the battles," Ingram...

aAs long ago as 1610 Galileo had observed that Jupiter has four very large moons,one of which is nearly the size of the planet Mercury . (Scientists later determined that the giant planet has more than six moons,)But what lay beneath those colorful clouds? Was there a solid surface? Or ...
