Earth orbits the Sun at anaverage distance (aka. semi-major axis) of 149,598,261 km – or one Astronomical Unit (AU). This orbit has a very minor eccentricity (approx. 0.0167), which means its orbit ranges from147,095,000 km (0.983 AU) at perihelion to 151,930,000 km (1.015 AU)...
According to the JPL, the MRO is one of the several orbiters that send data from Mars to Earth each day. Since entering orbit on March 10, 2006, the spacecraft has been collecting daily data about the planet's surface and atmosphere, including detailed views with its High Resolution Imagin...
After taking the OS on board, the MAV will launch off the solar-powered lander and deploy the OS container into Mars orbit, at least 190 miles (300 km) above the planet's surface. It will be plucked out of the void by the third big piece of this grand plan: ESA's Earth Return O...
摘要: This article presents the results of a fit of a model of the Martian satellite orbits to earthbased and spacecraft-based observations. An assessment of the orbit accuracies is given and the orbits are compared with those obtained by previous investigators.关键词:...

Mars - Red Planet, Orbit, Moons: Mars is the fourth planet out from the Sun. It moves around the Sun at a mean distance of 228 million km (140 million miles), or about 1.5 times the distance of Earth from the Sun. Because of Mars’s relatively elongated
So far, so good. But have you ever stopped to think how lucky we are to live on a planet that allows for such astraightforward set of leap year rules? What if Earth moved a bit faster or slower along its orbit or if it rotated at a different speed? What would our calendar look ...

Assuming that a refueling gas station is present at a given Lunar Distant Retrograde Orbit (DRO), we analyse ways of departing from the Earth to Mars via that DRO. Thus, the analysis and results presented in this paper add a new cis-lunar departure orbit for Earth-Mars missions. Porkchop...
