A A A  Electromagnetic waves, also called electromagnetic radiation, transfer energy when they collide with an object. Copies of the DVD are available through NASA's Central Operation of Resources for Educators (CORE). Mission:Science is provided by NASAa€™s Science Mission Directorate to engage students in NASA Science and showcase educational resources created by NASA and its partners. This unique NASA resource on the web, in print, and with companion videos introduces electromagnetic waves, their behaviors, and how scientists visualize these data. Each region of the spectrum is described and illustrated with engaging examples of NASA science.
Gasoline, for example, combustsA creating a gas that pushes the pistons in your car, causing motion (thrust). In rockets, the propellant is some variety ofA gas which is expelled from a nozzle, again creating thrust.The EM Drive instead uses electric power to bounce microwaves within a closed container to create thrust without any sort of propellant.


Up until the 19th century, scientists thought electricity and magnetism were completely separate things.
Even after a successful test last year those same people couldn’t explain its success.
A There were still doubts to the EM Drive’s ultimate viability for space travel as the test in 2014 did not take place in a vacuum. Well, a group a NASA’s Johnson Space Center went ahead and tested the EM Drive again in a vacuum. I09 did the math and discovered that a trip to our nearest stellar neighbor is theoretically possible:EM drives could also be used on multi-generation spaceships for interstellar travel.
A journey to Alpha Centauri, which is a€?justa€? 4.3 light-years away, suddenly wouldna€™t be so daunting.
An EM drive working under a constant one milli-g acceleration would propel a ship to about 9.4% the speed of light, resulting in a total travel time of 92 years.


But thata€™s without the need for deceleration; should we wish to make a stop at Alpha Centauri, wea€™d have to add another 38 years to the trip. Robots would be the obvious choice for this trip since we wouldn’t want to deliver a ship full of corpses to Alpha Centauri.
Maybe the next generation of EM Drive can push a little bit faster, allowing for humans to make the trip.
