Question 7
What type of mission collects information about multiple planets?
Sample returns.
Rovers.
Flybys.
Atmospheric probes.
Question 8
Why are neutrinos so difficult to detect?
There are very few of them, so collecting enough to study takes a long time.
They are theoretical and may not exist.
They move so fast they pass right through the telescope.
They don't interact strongly with matter, so they will not cause a reaction on a CCD imager.

- 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.arrow_forwardGiven what you've learned about the solar nebula idea, what do you believe the likelihood is of discovering livable planets in other solar systems? Learn more about this search by visiting NASA's Kepler mission and writing a half-page overview of the project.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? 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.arrow_forward
- Kepler-444 is one of many stars with terrestrial planets that is over 10 billion a) What do you think the spectral type of Kepler-444 might be? b) How do stars of this spectral type end their lives? c) If evolution followed a similar course on a habitable pranet around a star similar to Kepler-444, it would be 5 billion years more advanced than we are. Let’s try to project our future and see what happens. In particular, suppose our civilization gets motivated enough to colonize another planet. Kepler indicates that most stars have potentially habitable (and colonizable) planets, so roughly how far away is the typical “nearest" planet? d) The New Horizons probe on its way to Pluto took 9 years to travel 30 AU. If we could send colony ships with the same average speed, roughly how long would it take to reach the typical nearest planet? уears old.arrow_forwardYour 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_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_forwardActivity 2. Quest for Escape planet. Study and analyze the illustrations and determine whether the statements below are true or false.

A spacecraft must attain a speed of 11.2 km/s to leave the Earth's surface. 2. It is easier to leave the surface of Jupiter than Earth. 3. Escape velocity is affected by the planet's mass. 4. Mars has smaller escape velocity than Venus and Earth because it is farther from the sun. 5. The escape velocity of a planet is not affected by the sun's warping of space- time.arrow_forwardTheory and Observation.

When Mars is 90 million km from Earth, a) How long would it take for a radio wave from a video camera mounted on the back of a Mars Rover to tell ground control on earth that the Rover is about to go over a cliff? b) How long would it take for a radio signal from Earth to reach the Rover saying "STOP". c) Why do our Mars Rovers have to be "intelligent" enough to figure out how to deal with obstacles themselves?arrow_forwardThe gravity on Mars is about 38% that of Earth's gravity. Let's say some cargo has a mass of 15 kg here on Earth. First, what would be the weight of that cargo in kilograms on Mars? Explain your answer.
