March 19, 2003
This composite image of Earth and Mars was created to allow viewers to gain a better understanding of the relitive sizes of the two planets. The Earth image was aquired from the Galileo orbiter at about 6:10 a.m. Pacific Standard Time on Dec. 11, 1990, when the spacecraft was about 1.3 million miles from the planet during the first of two Earth flybys on its way to Jupiter. The Mars image was aquired by the Mars Global Surveyer in April of 1999.
