On Episode 169 of This Week In Space, Rod Pyle and Tariq Malik are joined by Rob Manning, JPL's Chief Engineer Emeritus, to look back at the Mariner 4 Mars mission 60 years later.
Six decades ago this week, the Mariner 4 probe sped past Mars, the first to succeed in this then-brash undertaking. The technology was unbelievably primitive, yet effective, sending back 22 low-resolution video frames of the Red Planet. On that day, the wee hours of July 15 at JPL in Pasadena, the Mars of the romantics died. What had long been viewed as a slightly colder, somewhat drier, near-twin of Earth ended up having just a trace of an atmosphere and looked more like the moon--bone dry and pummelled by craters.
