Orbital Maneuver
have you ever wonder how spacecraft travels to other planet ?
Launching the spacecraft required launch vehicle. To escape from earth gravity or to achieve escape velocity (11.2km/s) required much fuel. we separate out the fuel tanks in stages to decrease the payload or in other words to reach at escape velocity( high mass = much fuel).once we are out of earth's gravity i.e we are not going to fall back to earth and so we are in the orbit. satellite/spacecraft stays in the orbit until no external force is applied.
now suppose we want to change orbit to other planets orbit.but to change the orbit we required to propel the engine i.e required the fuel but at this stage we have not enough fuel to travel so ling distance. we can design our space craft to carry more fuel but our payload increases and require more fuel at launch vehicle i.e more space.
so how can we achieve require orbital change with minimum fuel the answer is Orbital Maneuver.
( maneuver is military word means change the place )
by using Orbital maneuver we can tackle the space constrains.
have you ever wonder how satellite/spacecraft placed into orbit
