Magnetic levitation (maglev) or magnetic suspension is a method by which an object is suspended with no support other than magnetic fields. Magnetic force is used to counteract the effects of the gravitational force and any other forces.
Transrapid 09 at the Emsland test facility in Lower Saxony, Germany A full trip on the Shanghai Transrapid maglev train Example of low-speed urban maglev system, Linimo. Maglev (derived from magnetic levitation) is a system of rail transport whose rolling stock is levitated by electromagnets rather than rolled on wheels, eliminating rolling resistance.
Maglev has the advantages of being quieter and smoother than wheeled transportation due to eliminating much of the physical contact between wheels and track. Since a maglev requires a guiding rail, it is mostly used in railed transport systems like trains.
On Earth, a mass-driver design could possibly use well-tested maglev components. To launch a space vehicle with humans on board, a mass driver's track would need to be almost 1000 kilometres long if providing almost all the velocity to Low Earth Orbit , though a lesser length could still provide major launch assist.
A magnetic bearing. A magnetic bearing is a type of bearing that supports a load using magnetic levitation.Magnetic bearings support moving parts without physical contact. For instance, they are able to levitate a rotating shaft and permit relative motion with very low friction and no mechanical w
There are plenty of reasons to look forward to spring. I, for one, am especially excited to celebrate warm-weather holidays like Easter, Mother’s Day and Cinco de Mayo (street-style tacos, FTW!).
Due to factors including the exponential nature of the rocket equation and higher propulsive efficiency than if a rocket takes off stationary, a NASA Maglifter study estimated that a 270 m/s (600 mph) launch of an ELV rocket from a 3000-meter altitude mountain peak could increase payload to low Earth orbit by 80% compared to the same rocket from a conventional launch pad.

Speaking to Vanity Fair in November, she said, “We always knew some people were not going to like it and that it was going to be too much for some people. But I stand by it. But I stand by it ...
