Repost from @erikkuna using @RepostRegramApp - On this day in 1969 an #nasa Atlas-Centaur rocket launched at 22:22 UTC from @nasakennedy LC-36A carrying the @nasajpl #mariner7 on its way to Mars. @spaceflight101- The #JPL Mariner 7 flyby probe reached it’s closest point to #mars on August 5th, 1969, a distance of only 2,130 miles. The mission concentrated on investigating the south polar cap of Mars. The Mariner flybys didn’t receive much love at the time from the media, since it came only a week after the Apollo 11 mission. #armstronged — #spaceflight101 — #nasa photo put into motion by #plotagraph
