For example, the Cassini spacecraft weighs ... flies ¿behind¿ the moon then the effect is an increase in the velocity (and orbital energy) of the spacecraft relative to the primary body, which ...

Today, we’ll explore the incredible potential offered by SSTO vehicles, and why building a practical example is all but ... propel the final stage up to orbital velocity. Credit: NASA Today ...

An orbital spacecraft must achieve what is known as orbital velocity, whereas a suborbital rocket flies at a speed below that. Orbital velocity is the speed that an object must maintain to remain ...

SpaceX is gearing up for a huge milestone: the first near-orbital-velocity launch of its combined Super Heavy booster and Starship upper stage. The Starship deep-space rocket system is scheduled ...

But to travel from low-Earth orbit (LEO) to farther orbits—or even the Moon—requires a different kind of ion thruster capable of achieving escape velocity and orbital capture maneuvers.

These engines burned very nearly for 10 minutes before shutting down, having reached an orbital velocity of 28,800 kph. For the first time since its founding, nearly a quarter of a century ago ...
