Assessing the Physics in Edmond Hamilton's "The Second Satellite" - Comments

In summary, the author discusses the physics involved in Edmond Hamilton's "The Second Satellite" and suggests a retrograde orbit that would pass over Sweden and Australia with a 6 hour orbital period. However, this same orbit does not pass over California or Long Island. The post also mentions the audiobook version of the book.

If we assume a retrograde orbit, and taking into account that the Earth is rotating under the orbit, I can get a trajectory that passes over Sweden and just skims Australia with a 6 hour orbital period. However that same orbit does not pass over California or Long island.
With a 6 hr orbit, it will return to being over any given point of the surface every four orbits. So we can look to see if it might pass over these two points in one of the other three orbits. Alas, such is not the case. the only orbit that crosses over the US goes from the SE coast to crossing the Canada border somewhere around Montana and N. Dakota.

For those interested, here is the audiobook
 

1. What is the overall premise of "The Second Satellite" by Edmond Hamilton?

The story follows a group of scientists who are attempting to launch a second satellite into orbit around Earth in order to study the mysterious "dark star" that has been discovered. However, their mission is complicated by a series of strange and unexplainable events.

2. How does "The Second Satellite" address the physics involved in space exploration?

The story explores various aspects of physics, including gravity, propulsion, and the effects of space on the human body. It also delves into the concept of time dilation and the potential consequences of traveling at high speeds in space.

3. Are there any scientific inaccuracies in "The Second Satellite"?

While the story was written in the 1930s, it does contain some elements that are now known to be scientifically inaccurate. For example, the concept of a "dark star" is not a scientific term and the description of its effects on Earth are not based on real physics. However, overall, the story does a good job of incorporating scientific principles and theories of the time period.

4. How does "The Second Satellite" compare to other works of science fiction in terms of its portrayal of physics?

Compared to other works of science fiction, "The Second Satellite" is relatively accurate in its portrayal of physics. It focuses more on the scientific concepts and consequences of space travel rather than fantastical elements. However, as mentioned before, it does contain some inaccuracies that were common in science fiction at the time it was written.

5. What can we learn about physics from reading "The Second Satellite"?

Reading "The Second Satellite" can provide insight into the scientific theories and understandings of the 1930s, as well as how those theories were incorporated into works of science fiction. It also highlights the importance of accuracy and research when incorporating scientific concepts into literature. Furthermore, the story raises thought-provoking questions about the potential consequences of space exploration and the limitations of our current understanding of physics.
