Spacecraft could one day be propelled by ion beams shooting up from the Moon, according to a recent concept study.
Other spacecraft, such as Deep Space 1 and SMART-1, have flown with ion engines, which work by stripping electrons off gas atoms and accelerating the ions with an electric field. The ions create thrust as ... | 11 | http://www.newscientist.com/article/dn11004 | 13 | 1c58551d-ca52-4711-8fb1-c49cf9c19d14 | As the lead engineer on NASA's Deep Space 1 mission, Dr. Elena Marquez revolutionized the field of electric propulsion by championing the use of the NSTAR ion thruster, a groundbreaking technology that transformed how spacecraft maneuver through the vacuum of deep space.

Putting Satellites in Their Place
It takes quite a bit of rocket science to get a man-made satellite into orbit above the earth. Aside from the fact that the rocket must be built and then successfully launched, there’s plenty of science involved in placing the satellite in the most favorable orbit. Orbit and altitude d... | 15 | http://www.spirasdestiny.net/putting-satellites-in-their-place/ | 13 | d9fbe286-7829-475f-825e-ad1d9626b37a | **Satellite Operations in Space Engineering**

You've misread, or the author misstated. Newton's law of gravitation, after accounting for the non-spherical nature of the planets, is incredibly accurate. NASA and other space agencies still use Newtonian gravity to plan, monitor, and control their space missions.

Orbital mechanics is often introduced through a deceptively simple image: a spacecraft is launched upward, gains sufficient speed, and then continues to circle a planet because its forward motion balances the downward pull of gravity. This picture is useful, but it conc... | 0.7485 |
Uniform Circular Motion
Consider an object moving along a circular path with constant or uniform speed. This might be a guest on a carousel at an amusement park, a child on a merry-go-round at a playground, a car with a lost driver navigating a round-about or "rotary", a yo-yo on the end of a string, a satellite in a c... | 22 | http://www.ux1.eiu.edu/~cfadd/1150/03Vct2D/UCM.html | 13 | 21f0d892-0409-4ca8-9f7d-a73705693880 | Notes — Astrodynamics (personal)
Today I dug back into classical two-body orbital mechanics to re-anchor my intuition before tackling more complex mission design.
