a.
More direct probes of the planetary surface are possible to detect signs of the building blocks of life.
b.
Rovers/landers can be outfitted with various tools and equipment that can be used to inform of us of the geological histories of each of the planets they visit.

Rock samples can be used to calibrate our estimations of the age of the solar system.
d.
The data collected can help improve our understanding of the evolution/development of our solar system.
e.
The engineering innovations developed to produce successful/viable rovers and landers on other planets can help lead to developments in the technology used here on Earth that may have taken far more time to develop without the limitations provided by space travel to foreign worlds.

- Why do scientists generality think that liquid water is necessary for the origin of life?arrow_forwardSince 1995, hundreds of extrasolar planets have been discovered. There is the exciting possibility that there is life on one or more of these planets. To support life similar to that on the Earth, the planet must have liquid water. For an Earth-like planet orbiting a star like the Sun, this requirement means that the planet must be within a habitable zone of 0.9 AU to 1.4 AU from the star. The semimajor axis of an extrasolar planet is inferred from its period. What range in periods corresponds to the habitable zone for an Earth-like Planet orbiting a Sun-like star?arrow_forwardScientists find evidence of a large meteor impact on the coast of the YucatánPeninsula in Mexico.
