Is There Life Elsewhere? After considering all the evidence to date about the possibility of extraterrestrial life, do you believe it is likely that we'll find microbial life elsewhere? Do you believe it is likely that we'll find intelligent life elsewhere? Defend your opinions, using arguments based on the full range of scientific issues discussed in this book.
If microbial life is possible elsewhere and chances of intelligent life.
Answer to Problem 1DQ
There is a possibility of existence of microbial life elsewhere due to common elements around universe and also various conditions on earth indicates similar condition in universe making human belief for possibility of microbial life. Intelligent life is also possible in universe.
Explanation of Solution
There is a great possibility of microbial life in universe.
Various evidences for such possibilitiesare as follows:
- The elements that are found on earth are very common in universe and carbon molecules which help in life formation can also be formed easily.
- Life on earth was possible even under harsh conditions which were supposed to be harmful. All these adverse condition made life adaptable to the changes in them with changing condition. These similar conditions are common in all over universe with less variation which makes humans belief that life can exist in universe.
- Earth became habitable after long time of formation of universe. This makes it evitable that there might be other planets too that had life on them.
According to the books it is believed aliens would be much advanced from human civilization. They will be intelligent and more superior. Some books even suggested aliens would come to help and solve problems of human.
Conclusion:
Thus, There is a possibility of existence of microbial life elsewhere due to common elements around universe and also various conditions on earth indicates similar condition in universe making human belief for possibility of microbial life. Intelligent life is also possible in universe.

- 13.87 ... 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?
