Textbook Question
Chapter 3, Problem 14EAP
Each of the following statements makes some type of claim. Decide in each case whether the claim could be evaluated scientifically or whether it falls into the realm of nonscience. Explain clearly; not all of these have definitive answers, so your explanation is more important than your chosen answer.
14. There are no lakes or seas on the surface of Mars today.

Activity #1. Compare and Contrast. Similarities and differences of Venus, Earth and Mars.
Do this on a separate sheet of paper.
1. Compare and contrast the three (3) terrestrial planets using table 1.
2. Provide explanations for your observations using table 2.
3. Answer the following guide questions.
Guide questions:
1. Does planet size affect gravity?
2. Why do you think Venus has the highest mean temperature among the three planets?
3. Is presence of water a primary factor for a planet to sustain life? Why or why not?
4. Based on your observations using table 2, what are the notable features that makes the
earth the only habitable planet among the three terrestrial planets?
5. What conclusions can you make?
This is a preliminary version of the Mars Project - to think about the time it takes to
complete a Mars mission. Consider the following simplified Earth to Mars transfer:
• Departs Earth
• Enter Mars orbit
• Orbit Mars orbit for some time
•
Exit Mars orbit to return
• Enter Earth orbit
a. What is the flight time, in days, from Earth to Mars? What is the return flight time?
[Answer: 258.83 days]
b. Where does Mars need to be (outbound) to reach it at the end of the Hohmann
transfer (tip: 180° "later").
[Answer: 44.329°]
c. To return to Earth with a Hohmann transfer, the opposite will need to be true:
Earth must be at a specific angle at the time of departure from Mars for the
spacecraft to reach Earth's orbit when Earth is there. What is that angle?
[Answer: -75.097°]
d. When is the first opportunity to return to Earth for that optimal Hohmann transfer?
[Answer: 454.70 days]
e. What is the total round trip time to Mars for this ideal Hohmann transfer?

In August of 2006, leading astronomers established new guidelines and declared that Pluto is no longer a planet. Which of the following is either false or least consistent with the new guidelines? Group of answer choices Pluto is by far the largest known object in the Kuiper belt, while Eris is the largest known object in the asteroid belt. A planet must have cleared the neighborhood around its orbit. Pluto is automatically disqualified from being a planet because its oblong orbit overlaps with Neptune's. A planet must have sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a nearly round shape. Pluto and the asteroid Ceres are both now classified as dwarf planets.arrow_forward
- We need to create a scale model of the solar system (by shrinking the sun down to the size of a basketball or ~30cm). First, we will need to scale down actual solar system dimensions (planet diameters and average orbital radiuses) by converting our units. There are two blank spaces in the table below. We will effectively fill in the missing data in the next set of questions. Use the example below to help you. Example: What is the scaled diameter of Mercury if the Sun is scaled to the size of a basketball (30 cm)? The actual diameter of Mercury is 4879 km The Sun's diameter is 1392000 km If the Sun is to be reduced to the size of a basketball, then the conversion we need for this equation will be: 30cm1392000km Here is how we run the conversion: 4879km×30cm1392000km=0.105cm or 0.11cm if we were to round our answer. This means that if the sun in our model is the size of a basketball, Mercury is the size of a grain of sand.
