In 2015, researchers concluded that Enceladus's subsurface ocean is probably global, instead of just being restricted to the south polar region. What had the Cassini spacecraft found, that led them to their conclusion?
a Enceladus wobbles slightly as it orbits Saturn, more so than it could if its ice shell were mostly frozen to the rocky interior.
b Enceladus is absorbing so much water (which is ejected by Saturn from its atmosphere) that there must be a global ocean under its icy surface.
c The number of large, lava-spewing volcanoes on Enceladus's surface is so high that they can only be the result of liquid water under the whole surface.
d The magnetic field of Enceladus is so strong that it can only be explained by a global ocean of salty water under the surface.
In the previous lab, we calculated the area in between Mars' and Jupiter's orbit to be ~1.6e18 km2. Since there are roughly 750,000 asteroids, how much area (in km2) is available for one asteroid? Use this calculation to argue whether you are likely (or not) to hit an asteroid while flying through the asteroid belt.
(Hint: To answer the first part of the question, find the area per asteroid)
The Mars Robotic Lander for which we are making these calculations is designed to return samples of rock from Mars after a long time of collecting samples, exploring the area around the landing site, and making chemical analyses of rocks and dust in the landing area. One synodic period is required for Earth to be in the same place relative to mars as when it landed.
Calculate the synodic period (in years) using the following formula:
1/Psyn = (1/PEarth) - (1/PMars)
where PEarth is the sidereal period of the Earth (1 year) and PMars is the sidereal period of Mars.
If 3/4 of a Martian year was spent collecting samples and exploring the terrain around the landing site, calculate how long the Mars Robotic Lander expedition took!

Compare that with the resolution limit of about 1 arc second for ground-based telescopes. (Hint: Use the small-angle formula, Eq. 3-1.) (Notes: Necessary data to derive the distance between the objects in that situation are given in the Celestial Profiles for Earth in Chapter 19 and Mars in this chapter. For the size of Phobos, use the maximum dimension given in the text.)arrow_forwardWould you expect as many impact craters per unit area on the surface of Venus as on the surface of Mars?

Use this calculation to argue whether you are likely (or not) to hit an asteroid while flying through the asteroid belt. (Hint: To answer the first part of the question, find the area per asteroid)arrow_forwardA spacecraft leaving Earth is deployed at burnout from its launch vehicle at 400 km altitude with flight path angle -10.0 degrees and speed 10.8 km/sec. ; Using Kepler's equation, determine how long it will take the spacecraft to cross lunar orbit (assume the Moon is on a circular orbit about Earth with 384,000 km radius, and ignore the lunar gravitational effects). Confirm your answer to part (a) using the appropriate Lambert TOF a. b. equation. If burnout speed is increased to 13 km/sec (still with flight path angle с. at -10.0 degrees and altitude 400 km), how much time can be saved for the trip to the Moon?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
- At an average opposition, the Earth and Mars are separated by 0.52 AU. Suppose an astronomer observes Mars at opposition and that seeing blurs the images to a resolution of 1.0 seconds of arc. What is the smallest surface feature the astronomer would be able to resolve on Mars? How does this size compare with the diameter of Mars?arrow_forwardDo you think that the transit method can be used to study the atmosphere of Mercury? [Hint: look at Figure 1]. Explain why, or why not.arrow_forwardTutorial Based on the orbital properties of Uranus, how far across the sky in arc seconds does it travel in one Earth day? The average orbital radius is 2.88 x 109 km and the period is 84.0 years. (Assume Uranus and the Earth are at the closest point to one another in their orbits.) How many full Moons does this distance cover if the Moon has an angular diameter of 0.5 degrees? Part 1 of 4 We first need to determine how fast the planet is moving across the sky. If we know the period and the distance between the Sun and the planet we can calculate the velocity using: 2ar which will tell us how many kilometers the planet travels in a day if we convert the period into days. days = (P years' |days/year Pdays days Submit Skip (you cannot come back)arrow_forward
- Jupiter's moon Metis has a radius of only 20 km, and a mass of 9 x 1016 kg. Answer the following: a) Calculate this moon's average density. b) Based on your result above, would you say that Metis is made primarily of rock or ice? Justify your answer. (Hint: Density of ice is 920 kg/m3)arrow_forwardThe value we have just calculated is the combined masses of Jupiter and Callisto! Their mass is in units of the Sun's Mass (MS) - we can convert this to units which are more familiar to us like kilograms by multiplying this answer by the scale factor (1.99x1030 kg/1 MS): (MJupiter + MCallisto) = ( MS) (1.99x1030 kg/1 Solar Mass) = _______x_10___ kg (I have already written the x 10 so you are reminded to write the exponenet of 10 in the scientific notation expression of your answer). Since you know from looking at pictures of Jupiter with its Galilean Satellites (look in your book at a picture if you have not already), that Callisto is much smaller than Jupiter - in fact it is less than 0.001 of Jupiter's size or mass, so the number we have just calculated for (MJupiter + MCallisto) is almost the same as MJupiter . How much more massive is Jupiter than the Earth? (The mass of Earth is about 5.98 x 1024 kg)arrow_forwardA Sense of Proportion: Mercury averages only 0.39 AU from the Sun, Venus 0.72 AU and Mars 1.52 AU. If you built a model solar system and represent the average distance from the Sun to Earth as 10 inches, how far would you place Mercury, Venus and Mars from the Sun?arrow_forward
