Nasa, a space travel centered company, has figured out a way to send messages back to earth from orbit, using lasers.  The system has been called the Deep Space Optical Communication system.  it is composed of lazer beams, which are highly focused, very powerful rays of light.  This technology has been used before, although only to the moon, which is about 5 percent of the distance to mars, so it is difficult to aim the beam.
