The spacecraft's final circular polar orbit
will be 426 miles (685 kilometers), at an inclination of 98.
From its vantage point in polar orbit
, OCO-2 will measure atmospheric carbon dioxide, discovering where it is being emitted and absorbed and revealing the roles of humans, plants and oceans on global CO2 levels.
But it will need every bit of this speed to get to Jupiter for its July 4, 2016 capture into polar orbit
The Department of Defense thus takes the attitude that the object recently found circling the earth in a polar orbit
probably was the last stage of Russia's Lunik III and not a reconnaissance satellite.
THE EUROPEAN Space Agency (ESA) has announced a new launch date for the first of a network of three meteorological satellites that will gather data in a polar orbit
, providing crucial weather information.
Owing to the rotation of the source of the field, Kepler's 3rd Law for the polar orbit
is not the same as that for the equatorial orbit, so that stable photon orbits are also different in the polar and equatorial orbits, showing that in the rotating configurations spacetime is no longer isotropic.
into a low-earth polar orbit
when launched from Vandenberg AFB, Calif.
The spacecraft is now undergoing a complicated series of manoeuvres designed to put it in a polar orbit
around Mars, and will not be brought online until January 4.
Alaska - not industry-guru Florida - is particularly prime to provide polar launch service, as launches into low polar orbit
are more efficient at high latitudes.
But the Global Surveyor has taken a longer route to Mars so it can get into a polar orbit
to begin a two-year mapping mission.
They were to go into polar orbit
for a two-year study of the Earth's magnetic shield.
The JPSS-2 mission is funded by the National Oceanic and Atmospheric Administration (NOAA) to provide global environmental data in low-Earth polar orbit
in support of NOAA's mission.
