Mariner 4 was launched November 28, 1964 on a 228-day mission to 
Mars.  The spacecraft carried instruments for eight 
interplanetary and planetary experiments including a TV camera.  
Mariner 4 passed Mars at a distance of 9,868 kilometers (6,118 
miles), recording and transmitting to Earth our first close-up 
picture of the red planet.  In 21 and a fraction of a 22nd 
picture, Mariner's TV camera scanned about one percent of the 
Martian surface, revealing ancient craters of varying size.  
Planetary science data, including pictures, were trasmitted over 
distances ranging from 215 million to 240 kilometers (134 million 
to 150 million miles).
