Deep-space ‘laser tag’ sets a record Mercury probe involved in longest-range laser communications By Ker Than Updated: 2:32 p.m. ET Jan. 5, 2006 Photo Source: Space.com | Credit: NASA/JHUAPL/CIW In a cosmic version of laser tag, NASA’s Messenger spacecraft and an Earth-based observatory successfully exchanged laser pulses with each other while millions of miles apart. The feat sets a new record for laser transmission in space, a process which may one day be used to communicate across interplanetary distances and provide scientists with a powerful tool to measure the movement of planets and test fundamental principles in physics...
