Chapter 8, Problem 49IF
Future Landing Site. Suppose you were in charge of a mission designed to land on Mars. Assume the mission carries a rover that can venture up to about 50 kilometers from the landing site. What landing site would you choose? Write a one-page summary of why you think your site is a good target for a future mission.

If we send astronauts to Mars, there will be a time delay anytime we send or receive messages to them here on Earth. Given that Mars is an average of 54.6 million km away from Earth, how long is this time delay for a 2-way 'round-trip' communication - sent to Earth, then back to Mars? (this might be important in emergency situations)
answer choices
a)About 4 minutes.
b)About 30 seconds.
c)About 10 seconds.
d)About 6 minutes.
The close encounter hypothesis was rejected because of the following reasons except for this reason.
b. It explained the planets were formed by gravitational disruption
c. It failed to explain the orbital motions of planets
d. It failed to explain why the solar system have 2 types of planets: terrestrial and jovian
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?
