This chapter discusses the ways in which gravitational attraction is utilized. It also summarizes the fundamental facts concerning the Earth's gravity field. Any measured value of gravity is a composite of many

The external gravitational field of the Earth is not axially symmetric but is irregular, described by series of the spherical harmonic functions. In the local inertial coordinate system the field is rotating following the rotation of the Earth. In the Newtonian interpretation the field is rotating ...

The earth seemed cold and dry and thick. When it rained, there was this smell...Ophiuchus wouldn't speak above a whisper. The river Ob has dried and withdrawn, so the island has become a mountain in a sea of forest. But something other than trees grows there. I swear it....
Jupiter's gargantuan magnetic field is the strongest of all the planets in the solar system, at nearly 20,000 times the strength of Earth's, according to theUniversity of Colorado at Boulder. The magnetic field trapselectronsand other electrically charged particles in an intense belt that regular...
Boeing’s CST-100 Starliner is still docked to the International Space Station, more than two months into a stay originally planned to be as short as eight days. Jeff Foust reports on the ongoing discussions at NASA about whether the spacecraft can safely return to Earth with astronauts on ...
