A huge "mother ship" has been established as an earth satellite.

Most of them had been involved with Earth orbiting satellites.

Earth's escape velocity is much greater than what's required to place an Earth satellite in orbit.

Kaplan also participated in efforts to launch the first Earth satellite.

With luck, he would lead the first expedition into outer space and establish a new earth satellite!

He had urged the launching of an earth satellite as early as 1947.

This phenomenon is quite noticeable for artificial Earth satellites, especially those in low orbits.

Chandra is an Earth satellite in a 64 hour orbit, and its mission is ongoing as of 2013.

The first Soviet space network had 13 stations and was designed to track Earth orbiting satellites.

In separate announcements, just four days apart, both nations publicly announced that they would launch artificial Earth satellites by 1957 or 1958.
