Question
Chapter 15, Problem 28A
To determine
The present-day obstacle to travel in high-speed spaceships for centuries and return to Earth.
Expert Solution & Answer
Answer to Problem 28A
There isn’t enough fuel or technology to travel with light speed.
Explanation of Solution
Introduction:
Interstellar travels for centuries require a huge amount of energy to sustain that long period.
At present, no such engine has been invented which can travel with the
Conclusion:
Thus, traveling beyond galaxies for centuries and then return to Earth would require a huge amount of fuel and the engine to travel with the speed of light which is not available to date.

Interplanetary Navigation. The most efficient way to send a spacecraft from the earth to another planet is by using a Hohmann transfer orbit (Fig. P13.87). If the orbits of the departure and destination planets are circular, the Hohmann transfer orbit is an elliptical orbit whose perihelion and aphelion are tangent to the orbits of the two planets. The rockets are fired briefly at the depar- ture planet to put the spacecraft into the transfer orbit; the spacecraft then coasts until it reaches the destination planet. The rockets are then fired again to put the spacecraft into the same orbit about the sun as the destination planet. (a) For a flight from earth to Mars, in what direction must the rockets be fired at the earth and at Mars: in the direction of motion, or opposite the direction of motion? What about for a flight from Mars to the earth? (b) How long does a one- way trip from the the earth to Mars take, between the firings of the rockets? (c) To reach Mars from the…arrow_forward
