What is the likely reason for Venus’s lack of water in any form? (a) The planet accreted little water during its birth. (b) The water is locked away in the crust. (c) The water was in the atmosphere, where molecules were broken apart by ultraviolet light from the Sun.

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.
Which of the following is least reasonable regarding the concept of a habitable zone?
Group of answer choices
M-type stars have wider habitable zones than G-type stars.
It is a region around a star where liquid water could be found on a planet's surface.
The habitable zone of a less massive star would be closer to the star.
In the course of millions of years, our habitable zone will slowly shift from Earth to Mars.
The Galactic habitable zone cannot be too close to the Galactic center because the radiation from the bright stars and supernovae in the crowded inner part of the Galaxy would probably be detrimental to life.
The principle cause of our intense interest in Mars in the decades before the dawn of the space age was that
Answers:
A.
a few astronomers believed that they saw evidence of an intelligent civilization on Mars.
B.
Mars has seasons just like the Earth and therefore should be inhabitable by humans.
C.
Mars has an unusual surface color and global dust storms, creating strange weather patterns.
D.
Mars has unusual orbital properties making our understanding of its motion around the Sun very difficult.

- Why 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_forwardImpact Energy. Consider a comet about 2 kilometers across with a mass of 4 × 1012 kg. Assume that it crashes into Earth at a speed of 30,000 meters per second (about 67,000 miles per hour). a. What is the total energy of the impact, in joules? (Hint: The kinetic energy formula tells us that the impact energy in joules will be 1 × m × v2, where 2 m is the comet’s mass in kilograms and v is its speed in meters per second.) b. A 1-megaton nuclear explosion releases about 4 × 1015 joules of energy. How many such nuclear bombs would it take to release as much energy as the comet impact? c. Based on your answers, comment on the degree of devastation the comet might cause.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_forward
- Your goal is to try and make the timeline of the Perseverance mission play out the way you remember it. You want to make sure that the Perseverance rover gets built and sent to Mars, just like your "memory of the future", i.e. your memory of the summer of 2020. In the space provided below, write a description, in your own words, of why the Perseverance rover has the potential to do great science. Here are the things to focus on: What are the two or three most special things about Perseverance, when it comes to the search for possible ancient life on Mars? In particular, you want to make sure to describe and explain the one particular thing that Perseverance will hopefully do, which will start the long process of giving scientists the opportunity to learn about Mars in a way they never could do before.arrow_forwardFully describe the greenhouse effect. How is this important for life on earth?arrow_forwardWhich 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.arrow_forward
- What is the runaway greenhouse effect, and how might it have altered the climate of Venus?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_forwardTheory and Observation. Discuss the interplay between theory and observation that has led to our modern theory of solar system formation. What role does technology play in allowing us to test this theory?arrow_forward
- Considering what you learned from the solar nebula theory, how likely do you think it is to find habitable planets in other solar systems? Visit NASA’s Kepler mission to learn more about this search, and write a ½ page summary on the mission.arrow_forwardAt present, NASA is planning a mission to Europa, to try and assess its habitability. An argument might also be made for Enceladus, however. Let's imagine you had to pick one of those moons to send an uncrewed (i.e. robotic) mission to. The spacecraft will probably orbit the giant planet (Jupiter in the case of Europa, Saturn in the case of Enceladus), and make many flybys of the moon you're studying. Which moon would you pick, and why? The goal here is to briefly discuss the pros and cons of each moon as a target for a mission. You don't even have to have a strong preference either way, just lay out a few pros and cons for each.arrow_forwardAt present, NASA is planning a mission to Europa, to try and assess its habitability.
