Chapter 9, Problem 17EAP
Surprising Discoveries?
Suppose we were to make the following discoveries. (These are not real discoveries.) In ligh of your understanding of planetary geology, decide whether the discovery should be considered reasonable or surprising. (In some cases, both view can be defended.) Explain your answer, if possible tracing your logic back to the terrestrial worlds' fundamental properties of size, distance from the Sun, and rotation rate.
17. New photographs reveal sand dunes on Mercury.

How many impacts would you expect to strike a 100m2 region in one hour during Earth’s formation, assuming that Earth grew to its present size in 10 million years from particles averaging 100 grams each? (Hint: Assume that Earth had its current radius of 6378km.) (Notes: The surface area of a sphere is 4pir2 ; 1yr=3.2x107 .)
a. About 1300.
b. About 13 .
c. About 13,000.
d. About 130
Planetary scientists are hoping that the samples collected by the Perseverance Mars rover will eventually be collected by other robotic spacecraft and returned to Earth. Even if Perseverance could collect samples from all over Mars's surface, why wouldn't this tell us what the entire planet is made of?
Group of answer choices
The deep interior of Mars has had its composition altered (compared to the surface) by the impacts of asteroids that plunged almost all the way down to Mars's center.
Since Mars has a powerful magnetic field, it must have a liquid-iron portion of its core, and this material can't be collected by a rover on the surface.
Early in its history, Mars differentiated into layers of materials that had different densities, much like the Earth did.
Mars has such a low density that most of its interior must be made of liquid water and ice, so rocks from the surface simply won't be representative of the deep interior.
Which of the following planetary traits is well established?
choose one of the following:
a) Mercury has a similar compositon to that of our moon, in that they both have a substantial metal content.
b) Venus rotates more rapidly than Earth, but in the opposite direction.
c) Earth's atmosphere exhibits a slightly stronger greenhouse effect than that seen on Venus.
d)Astronomers have precisely calculated the mass of Mercury thanks to artificial satellites sent from Earth.

- We believe that all of the terrestrial planets had similar histories when it comes to impacts from space. Explain how this idea can be used to date the formation of the martian highlands, the martian basins, and the Tharsis volcanoes. How certain are the ages derived for these features (in other words, how do we check the ages we derive from this method)?arrow_forwardFor which of the following reasons (select all that apply), is it useful/important to send rovers to other planetary bodies in our solar system? 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. c. 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.arrow_forwardWhy Wait? To explore a planet, we often send first a flyby, then an orbiter, then a probe or a lander. There’s no doubt that probes and landers give the most close-up detail, so why don’t we send this type of mission first? For the planet of your choice, based just on the information in this chap- ter, give an example of why such a strategy might cause a mission to provide incomplete information about the planet or to fail outright.arrow_forward
- CO2 and planetary warming: understanding Earth’s complicated atmosphere Mars has an atmospheric pressure of 6 mbar (compared with Earth atmosphere pressure of 1013 mbar), 96% of which is CO2. The average calculated temperature of Mars is -57°C, whereas the actual average temperature is -55°C so that the amount of warming due to CO2 is only 2°C. On the other hand, the average calculated temperature of Earth, with 0.4 mbar of CO2, is -19°C, whereas the actual average temperature is 15°C so that the amount of warming due to CO2 is 34°C, much greater than that on Mars, which has higher CO2 concentration. Explain how this is possible.arrow_forwardWhy do small planets cool faster than large planets? Choose any two of the five Terrestrial worlds and calculate for each one the ratio of its surface area to its volume. Why is this ratio important? (Hint: Does this ratio have anything to do with the ability of a planet to lose internal heat?) (Note: The surface area of a sphere is 4r2, and the volume of a sphere is 43r3.)arrow_forwardIf, in the remote future, we establish a base on Mercury, keeping track of time will be a challenge. Discuss how to define a year on Mercury, and the two ways to define a day. Can you come up with ways that humans raised on Earth might deal with time cycles on Mercury?arrow_forward
- Describe the four stages of Terrestrial planet development.arrow_forwardPretend you are a NASA executive or a legislator. Design a new mission in our solar system. Pick any object in the system and decide whether you want to send an orbiter, a lander, a rover, some combination or those, a manned mission, or something else. What interests you about this object? What science questions can we answer? In basic terms, what kind of scientific instruments might you want to include on your mission? Justify your decisions with what you know about the scientific method, astronomy techniques, and the object itself from this class.arrow_forwardLearn about current and planned missions to study a terrestrial planet's atmosphere (including Earth). Write a one-page essay describing the mission and the lessons learned.arrow_forward

Most of the spaceflight missions to the outer planets have been flyby missions, but two of them were orbiters. Which of these two spacecraft orbited giant planets? Check the correct two.
