The average vertical speed in a soft landing should be about per second or less. A soft landing can be achieved by * Parachute—often this is into water. * Vertical rocket power using retrorockets, often referred to as VTVL (vertical landing referred to as VTOL, is usually for aircraft landing in a level attitude, rather than rockets) — first achieved on a suborbital trajectory by Bell Rocket Belt and on an orbital trajectory by the Surveyor 1. * Horizontal landing, most aircraft and some spacecraft, such as the Space Shuttle, land this way. * Being caught in midair, as done with Corona spy satellites and followed by some other form of landing. * Reducing landing speed by impact with the body's surface, known as lithobraking Lithobraking is a whimsical euphemism used by spacecraft ...
