The shuttle orbits the earth every 90 minutes...so if the satellite is doing a circumpolar orbit in 102 minutes..that means its apogee and perigee must be both higher and further away which in turn means a slower overall orbital speed.. and a greater distance from the earth..
Closer orbits need higher delta v's to stay aloft..
Keplerian orbital elements are available for most acknowledged satellites and even the so called "darks" launch times and probable orbits are available from dedicated satellite hunters and several Satellite tracking programs like SATTRACK & JTRACK can graphicly display multiple orbital elements of both man made and planetary objects.

The speed of any satellite depends on its orbital diameter. So 102 minutes from north pole to south pole is not same for all the Polar satellites. Polar satellites are very close to earth anywhere between 700 to 800 km of altitude and hence they orbit / rotate around Earth via poles pretty fast. Whereas geosynchronous satellites are stationed at an altitude of 36,000 km and hence they take one full day to make one orbit around Earth. Polar satellites are also called as Sun synchronous satellites.

certainly neither penguins or polar bears stay on the South Pole. this is purely too chilly, too, severe and too a techniques inland to help any existence. on the coast of Antarctica there's a form of existence, consisting of penguins and orcas. the main in all probability reason that the North Pole has greater suitable species and a much better selection of existence is as a results of the fact this is a lot warmer than the South Pole. the reason the North is warmer than the South is that the North Pole is interior the midst of a physique of water together as the South Pole is interior the midst of a huge continent, and water has a tendency to reasonable temperature.

the shuttle zips along while in orbit at approx 17,000mph. The earth is just a little bit over 24,000 miles in circumference. Satellites have different speeds depending upon their orbital altitudes. So, yes, a satellite going somewhere near 17,000mph could easily go an orbit in just under two hours.
