First close-up image of Mars, from the Mariner 4 spacecraft
March 20, 2003
Mariner 4 image, the first close-up image ever taken of Mars. This shows an area about 330 km across by 1200 km from limb to bottom of frame, centered at 37 N, 187 W. The area is near the boundary of Elysium Planitia to the west and Arcadia Planitia to the east. The hazy area barely visible above the limb on the left side of the image may be clouds.
