Aug 2, 2019 - Mars Atmosphere - FILE: Lost in the glare following the Apollo 11 Moon landing, two intrepid robotic spacecraft flew by Mars in the summer of 1969 and returned photographs and a trove of scientific information. Launched on Feb. 25 and March 27, respectively, Mariner 6 and 7 arrived at Mars just five days apart despite being launched a month apart. After a flight of 156 days from Earth, Mariner 6 flew within 2,132 miles of Mars on July 31, roughly twice as close as Mariner 4 s flyby in 1965. Controllers lost contact with Mariner 7 for seven hours just five days before its planned flyby, but by Aug. 2, after quick replanning, they restored the spacecraft to full capability as it began its encounter with Mars.
