Mars - The Search Begins (1974): #Mars, including speculation on what form that life might take, many of the core ideas are still current 1/2 century on. The film was made just before NASA's Viking landers were launched in 1975 to begin the search but after the great success of the orbiter Mariner 9 - Olympus Mons was still called Nix Olympica and model makers believed that the sky over the Martian landscape was a deep blue.

Planning Considerations Related to Contamination Control for the Return and Analysis of Martian Samples: #MarsSampleReturnMission
Interesting corollary to the #Perseverance discovery in the Bright Angel formation on #Mars making headlines 1 1/2 months ago: at a public talk in Bochum as part of a mathematics outreach event - #Life Detection scale #MarsSampleReturnMission the rating could jump up to 5 or 6 after lab analysis.
Green also remarked that the sample tubes dropped by Percy are up for grabs for *any* spacefaring nation capable of doing a MSRM - including China though they don't plan to go after the Percy samples with their upcoming #Tianwen3 mission (https://en.wikipedia.org/wiki/Tianwen-3) as far as he has heard. And regardless of where they'll get their own samples they could advance the case for life, perhaps even extant, on Mars a lot - which Green feels has been all but made in the past decades of Mars research anyway. Oh, and he also thinks terraforming Mars is quite viable ...
