More amazingly the laser communication was 25 million miles away! As opposed to radio waves, lasers can pack a lot more data into a signal and subsequently allow much more data to be transmitted.<\/p>\n<p>If you think Skype has latency now, wait till your grandkids are using it on one of Jupiter\u2019s moons!<\/p>\n<p><img decoding=\"async\" hspace=\"5\" src=\"http:\/\/voip-blog.tmcnet.com\/blog\/rich-tehrani\/uploads\/space.jpg\" align=\"left\" vspace=\"5\" border=\"0\" \/>A major challenge with laser communications in space is keeping transmitter and receiver locked onto each other. This is like trying to aim the beam of a very strong laser pointer, akin to the type used in a conference room, at a target millions of miles away.<\/p>\n<p>Radio waves radiate outwards from a transmitter in spherical ripples rather than pencil-thin beams like lasers. So the receiver and transmitter in a laser-based communication system have to be pointed very precisely.<\/p>\n<p>The record-setting effort is described in the Jan. 6 issue of the journal Science. <a href=\"http:\/\/news.yahoo.com\/s\/space\/recordsetforspacelasercommunication;_ylt=AlS.Ek89QPO4Jsv_Jpn6Ygus0NUE;_ylu=X3oDMTA3ODdxdHBhBHNlYwM5NjQ-\">Story<\/a>.<\/p>\n<p>I sense a new Verizon Wireless \u201cCan you hear me now\u201d commercial being developed as a result of this story.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>NASA has just recently announced that they have communicated bidirectionally from a an earthbound space station with a spacecraft using a laser.
