Mars Rover Scooping

There have been four successful robotically operated Mars rovers, all managed by the Jet Propulsion Laboratory: Sojourner, Opportunity, Spirit and Curiosity. On January 24, 2016, NASA reported that current studies on Mars by Curiosity and Opportunity (the latter now defunct) would be searching for evidence of ancient life, including a biosphere based on autotrophic, chemotrophic or chemolithoautotrophic microorganisms, as well as ancient water, including fluvio-lacustrine environments (plains related to ancient rivers or lakes) that may have been habitable. The search for evidence of habitability, taphonomy (related to fossils), and organic carbon on Mars is now a primary NASA objective. In June 2018, Opportunity went out of contact after going into hibernation mode in a dust storm. NASA declared the end of the Opportunity mission on February 13, 2019, after numerous failures to wake up the rover.



Have you ever had one of those days fishing where it seemed like you could do no wrong? Like everything you tried resulted in fish being caught? And not only fish being caught, but large fish being caught? This was all probably due to the moon and what phase the moon was in. That's right, something as simple as what phase the moon is in can have an effect on your fishing success. On July 20, 1969, astronaut Neil Armstrong radioed back from the surface of the Moon, "... the Eagle has landed". Most of us believe that the landing occurred as broadcast. Not all, however. More than 30 years after the fact, Fox TV aired "Conspiracy Theory: Did We Really Go to the Moon?". In doing so, the Fox entertainers unleashed a lively cabal of kooks and NASA-bashers on a scientifically naive audience without benefit of editorial balance. Polls suggest that perhaps 6% of Americans believe in the authenticity of these claims. Going to the moon again is causing far more controversy today than it could have back in the sixties. Some Americans doubt we can afford it and others are not sure they have seen the "giant leap for mankind" that the first moon shot promised. It depends on who you ask but don't dare ask me. I didn't think the first moon landing had much significance for reasons that few people share with me.
