The Fountains of Paradise
The novel focuses primarily on a project proposed by the main character, Vannevar Morgan, known as the Orbital Tower. The tower is to stretch from the Earth's equator to a satellite that is in geostationary orbit. Such a structure would greatly reduce the cost of sending people and supplies into space.
The main story is framed by two other stories. The first one tells of King Kalidasa, living thousands of years before Morgan is born, who is constructing a large tower. The other story, taking place long after Morgan has died, deals with aliens making contact with Earth.
Due to many technical issues, there are only two locations on Earth where the Orbital Tower can be built. One is in the middle of the Pacific Ocean, and the other is Sri Kanda (now Sri Lanka). However, there is a Buddhist temple on the island, and Mahanayake Thero, the head of the order, refuses to give permission to begin construction.
Hearing of the difficulties, a group of people living on Mars contacts Morgan and suggests that the tower be built there instead. It would be smaller than the one planned for the Earth and reach from Mars to one of its moons, Deimos.
After a few setbacks, including some fatalities, construction of the tower gets underway. Although the engineer's heart is failing, he rides up the tower to take food and oxygen to a group of stranded students and their professor. After overcoming serious difficulties he succeeds, then dies of a heart attack on the way back down.
