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.
Among the ringed gas giant planet Saturn's amazing collection of 62 diverse, bizarre, and beautiful moons and moonlets, sometimes one of them just seems to stand out in the crowd. Such a moon is little Methone. Looking like a shiny white egg in Space, and composed of very lightweight fluffy stuff, Methone is less dense than any other known moon or asteroid in our Solar System. In March 2013, astronomers announced at the 44th Lunar and Planetary Science Conference held in the Woodlands, Texas, that this strange little 5-kilometer-size moon is one of a batch of Space eggs in orbit around Saturn! The Moon represents tides, phases and mysterious rhythms. As you settle into the reality of living and breathing with another person, you begin to feel 'in sync' with them-or perhaps not! If your emotional needs and expressions seem to interact and flow harmoniously as time goes on, you can bet that your lunar energies are connected. If, on the other hand, you find yourself drawing a complete blank as to what your partner is thinking or feeling, then this lunar connection is missing in some way. When we learn these influences that the moon holds over us and astrological phenomena, we can use this information to our advantage. For example, during the new moon most people are not capable of rational thought. Knowing this can help you to avoid major decision making during the time of the full moon.
