Magnetic launch paths.

Part eight eletro-magnetic launches from Cape Canaveral. As NASA is forced to compete, thanks to its recent budget cuts, is trying to get around the loss of money without  a big loss of their space program this there renowned monopoly. NASA's solution launch a craft to hyper-sonic speeds with a gigantic electromagnetic rail gun, then have an air-propelled scram-jet take over after launch. due to atmosphere mach five causes atoms to stick to the skin of the craft there are solutions to repel these into a streamline. The proposed launch method will definitely improve NASA image as a world leader while keep costs down while continuing on our path to learn more about our universe. 
Plus you can't go wrong with a launch mechanism that involves using electromagnetic energy to fling a spacecraft to about Mach 3. Thus sending a man out into space hasn't really gotten more cost-effective over the decades. So as they don't want to waste as many billions on disposable rocket stages., but again, the amount of energy needed to send a man (or woman) into orbit just costs too much time and resources. by conventional launching as this be a little like a space port with reusable parts only fuel is needed two small oxygen tanks. for this sub orbital cargo space craft. This is nightlight scenario but ‘Inter changeable satellites turned into probes with repairable parts for planetary or planet studies and retrieval parts’ would bring about a solution so to conserve resources. 
This is where nonoperational probes or orbiting satellites can be refitted in space and avoiding the kessler effect (collision cascading or ablation cascade causing plumes rendering each other inoperative , proposed by the NASA scientist Donald J. Kessler in 1978, is a scenario in which the density of objects in low Earth orbit called (LEO) is high enough that collisions between objects could cause a cascade-each collision generating space debris which increases the likelihood of further collisions. One implication is that the distribution of debris in orbit could render space exploration and even the use of satellites, unfeasible for many generations. Every satellite, space probe, and manned mission has the potential to create space debris. A cascading Kessler syndrome becomes more likely as satellites in orbit increase in number and old satellites become inoperative. One technology proposed to help deal with fragments from 1 cm to 10 cm in size is a laser broom, this proposed multimegawatt land-based laser that could de-orbit debris. The side of the debris hit by the laser would change trajectory and create a thrust that would change remains of the fragment until it would re-enter harmlessly.
Orbital decay is much slower at higher altitudes where atmospheric drag is insignificant. Slight atmospheric drag, lunar perturbation, and solar wind drag can gradually bring debris down to lower altitudes where fragments finally re-enter. But this process can take millennium at very high altitudes. The Kessler Syndrome is especially insidious because of its domino effect and plume paths wherein impacts between objects of sizable mass spills of debris from the force of collisions. The shrapnel can then hit other objects, creating even more space debris. based on the assumption weapon stockpiling. So if a large enough collision or explosion were to occur, such as between a space station and a defunct satellite, or as the result of hostile actions in space, then the resulting debris cascade could render low Earth orbit essentially impassable. So  designers of a new vehicle or satellite are frequently required to demonstrate that it can be safely disposed of at the end of its life. For an example by use of a controlled atmospheric re-entry system.
