As said in the title... all the robotic planetary missions launched in the 70's left a spare spacecraft on the ground (and later, at the NASM aerospace museum). There were good reasons for that - providing spares - ground testing - backup in case of failures (Mariner 8...) Soooo ...by 1978...

Yep George Levin has stirred this up again with a new opinion piece in Scientific American. https://blogs.scientificamerican.com/observations/im-convinced-we-found-evidence-of-life-on-mars-in-the-1970s/ Here’s a support article...

The first of the "Thousand Astronomical Unit" space probes designed from the late 70's into the 80's. Nuclear electric propulsion would send the craft on a fifty-year mission into interplanetary space to test technologies for a future true interstellar mission, for deep-space science and to map...

In other words, steampunk in the space age. ;D ORIGINAL CAPTION: AREE is a clockwork rover inspired by mechanical computers. A JPL team is studying how this kind of rover could explore extreme environments, like the surface of Venus. Credit: NASA/JPL-Caltech...

After the cancellation of Voyager(Mars) in 1967 NASA started up a new series of studies to come up with a spacecraft for the 1973 launch opportunity. This Martin-Marietta designed soft-lander of 1969 was intended to put the maximum payload weight on the surface of Mars using a mission profile...

1965 (Pre-Mariner 4 Atmosphere) design for a hard landing capsule designed to take 1 high resolution photograph of the surface of Mars and then transmit it back to Earth over a period of four days. The camera used would appear to be a distant ancestor of those eventually used on the Viking...

Concerned about the cost of Viking 1 & 2, NASA looked at lower cost alternatives for the 1977 & 1979 Mars launch opportunities . One of the proposed missions was to use a modified version of the Pioneer Venus Orbiter to carry six RTG powered penetrators to Mars. Once the spacecraft entered...

Just after President Kennedy May 1961 call for a lunar landing before the end of the decade, there was a lot of proposals for boosters capable to take a manned lander to the Moon: ever growing Saturns, and Novas built with the most diverse combination of stages, liquid, solid and nuclear. One of...
