For which of the following reasons (select all that apply), is it useful/important to send rovers to other planetary bodies in our solar system?
O a. 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.
O b. The data collected can help improve our understanding of the evolution/development of our solar system.
O. 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.
O d. More direct probes of the planetary surface are possible to detect signs of the building blocks of life.
O e. Rock samples can be used to calibrate our estimations of the age of the solar system.
The Search for Extraterrestrial Intelligence (SETI) makes use of a huge, multi-billion-dollar network of radio telescopes around the world, all built solely for the purpose of contacting alien civilizations.

In Table 2, there is a list of 15 planets, some of which are real objects discovered by the Kepler space telescope, and some are hypothetical planets. For each one, you are provided the temperature of the star that each planet orbits in degrees Kelvin (K), the distance that each planet orbits from their star in astronomical units (AUs) and the size or radius of each planet in Earth radii (RE). Since we are concerned with finding Earth-like planets, we will assume that the composition of these planets are similar to Earth's, so we will not directly look at their masses, rather their sizes (radii) along with the other characteristics. Determine which of these 15 planets meets our criteria of a planet that could possibly support Earth-like life. Use the Habitable Planet Classification Flow Chart (below) to complete Table 2. Whenever the individual value you are looking at falls within the range of values specified on the flow chart, mark the cell to the right of the value with a Y for…

- Since 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.
