A spacecraft in orbit around Moho.An orbit is an elliptical path around a celestial body. The point on an orbit which is closest to the orbited body is called the periapsis and the furthest point is the apoapsis. These points are indicated on the map view as "Pe" and "Ap", ...

Robert W. Farquharfirst used the name "halo" in 1966 for orbits around L2which were made periodic using thrusters.[1]Farquhar advocated using spacecraft in such an orbit beyond the Moon (Earth–MoonL2) as a communications relay station for anApollomission to thefar side of the Moon. A spa...
Figure 5 shows the satellite's field of view around the apogee. The Earth completes half a rotation in twelve hours, so the apogees of successive Molniya orbits will alternate between one half of the northern hemisphere and the other. For the original Molniya orbit, the apogees were placed...
Understand how the Earth remain stable in orbit around the sun How Earth is able to remain in orbit by balancing speed and gravitational pull from the Sun. See all videos for this article The orbit of a planet is, if unaffected by the attraction of another planet, elliptical; someelliptical...
So it’s not so much that you deorbit when you’re exactly opposite side of the Earth. Instead, you deorbit when you’re opposite of where your landing zone will be – since the Earth is always rotating below. De-orbiting – periapsis lowering on opposite side of the planet – (even...
“Maven will complement NASA’s other Martian robotic explorers—and those of our partners around the globe—to answer some fundamental questions about Mars and life beyond Earth.” Following orbit insertion, MAVEN will begin a six-week commissioning phase that includes maneuvering into its final ...

A highly elliptical orbit (HEO) is an elliptic orbit with high eccentricity, usually referring to one around Earth. Examples of inclined HEO orbits include Molniya orbits, named after the Molniya Soviet communication satellites which used them, and Tundr
