Why are we sending a spacecraft and not people to Saturn ?
Homework Answers
?Spacecraft are robots that represent humans in space. Neither humans nor robots can survive unprotected in the dangerous environment of outer space, but humans require a greater degree of protection and safety

Suppose we decide to send a spacecraft to Saturn, using one
transfer orbit that connects the earth to Saturn. Craft starts in a
circular orbit (centering the Sun) close to Earth (radius 1 AU) and
is to end up in another orbit near Saturn (radius 10 AU). Ignore
the effects of other planets in the solar system.
a) Find the eccentricity
of the transfer orbit that gives the shortest time of travel.
b) Use Kepler's third law to estimate the...

2. To get from Earth to Saturn as economically and quickly as possible, spacecraft make use of an elliptical transfer trajectory called the Hohmann transfer orbit. As shown in the diagram, below, Hohmann transfer facilitates a smooth transition between two planetary bodies in roughly circular orbits located on the same plane. For our solar system, this plane is known as the ecliptic. Using data you can find online for the orbits of Earth, Saturn and the Sun and assuming that...

The rocket used for the human lunar missions was the Saturn V rocket. At liftoff the mass of the rocket was 2.80 x 106 kg and the thrust of the five F1 engines is 3.45 x 107 N. (a) Draw the force diagram of the rocket. (b) What is the initial acceleration of the spacecraft? (c) The rocket uses 1.81 x 105 kg of fuel per second. What would be the acceleration of the mass of the rocket 0.5 and...

In the 1800's, writers suggested sending people to the Moonby firing a space capsule from a 206-m-long cannon with a launch speed of 10.9 km/s. What would be the unrealistically large acceleration experienced by the space travelers during launch? Express your answer in m/s2. Ans. 288373.786
