At present we lack any technology that could allow us to search for life in the cores of these giant planets; even if life might exist there, the search for it will have to await new technological developments. Could there be life on moons or other small bodies? Yes Moons of Jovian planets differ from terrestrial planets because they tend to contain a great deal of ice due to being formed in parts of the solar system where it was cool enough for ices to condense from the solar nebula Prospects are good for larger moons Probably not on smaller moons How do robotic spacecraft work? Operate with preprogrammed instructions Flyby: a spacecraft on a flyby goes past world just once and then continues on its way Orbiter: an orbiter is a spacecraft that orbits the world it is studying, allowing longer-term observation during its repeated orbits Lander or probe: these spacecraft are designed to land on a planet’s surface or probe a planet’s atmosphere by flying through it. Some landers have carried rovers to explore wider regions. Sample return mission: a sample return mission requires a spacecraft designed to return to Earth carrying a sample of the world it has studied What are some key spacecraft missions for astrobiology? All spacecraft missions have at least some connection to astrobiology Among the most important missions at present are those studying Mars, Titan, and Venus

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
