The no-namer picked up escape speed.

The Earth's escape speed can be derived from "g", the barycentric acceleration due to gravity at the Earth's surface.

It blasted for three minutes and fifty secOnds and cut off at an altitude of eight hundred seven miles, at escape speed in a forty-six-hour -orbit.

Max reflected that the ship had already passed escape speed for the Nu Pegasi system before he had been relieved; the body would take an open orbit.

The first burst tends to accelerate to the escape speed, which is times the circular orbit speed, and the second tends to zero.

For Earth's escape speed this requires a catapult three hundred twenty-three kilometers in length.

But no matter how he threw them, final velocity at Terra would be close to Terra's escape speed, near enough eleven kilometers per second as to make no difference.

No, doesn't take a century of pain to accelerate to Luna's escape speed at three gravities, merely feels so.

Underwater recordings show herring constantly cruising at high speeds up to 108 cm per second, with much higher escape speeds.

I asked George about it and he said, no, the escape speed was about five hundred feet per second and who had been filling me up with nonsense?
