description = <b>Program: Advanced Commercial Applications<br>Type: <color=blue>Optional</color></b><br><br>A Tundra orbit is a highly elliptical geosynchronous orbit (note: not geostationary orbit) with a high inclination (usually near 63.4) and an orbital period of one sidereal day. A satellite placed in this orbit spends most of its time over a chosen area of the Earth, a phenomenon known as apogee dwell. The ground track of a satellite in a tundra orbit is a closed figure eight. An extreme version of this orbit puts the perigee around 1000 km and the apogee around 70,000 km. The orbit in this contract is actually using data from the Sirius satellites, the only known satellites using a Tundra orbit.<b>

completedMessage = Success! The Tundra orbit is highly eccentric and lets the satellite spend most of its time over a point in the high latitudes.
