Highly elliptical orbit Highly elliptical orbit 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 tundra orbits. Such extremely elongated orbits have the advantage of long dwell times at a point in the sky during the approach to, and descent from, apogee. Bodies moving through the long apogee dwell appear to move slowly, and remain at high altitude over high-latitude ground sites for long periods of time. This makes these elliptical orbits useful for communications
From the Earth to the Moon (film) laws. When it is discovered that Virginia has stowed away, Nicholl cooperates with Barbicane in a desperate attempt to save her. Sharpe is knocked out, and he and Virginia are placed in the safest compartment of the ship.

They are able to signal to the young couple that they have reached the Moon safely. Location shooting for "From the Earth to the Moon" took place in Mexico. Various
