Feather-based Jacobean Space Chariot 173
simonmsh writes "The article Cromwell's moonshot: how one Jacobean scientist tried to kick off the space race describes 17th century plans to build a space chariot out of springs, feathers and gunpowder. The design was based on the idea that gravity disappeared at an altitude of 20 miles, which was called into question by Hooke ? and Boyle ? 's work.
It sounds like the plot of a Neal Stephenson book." Said book, and its sequels are phenomenal.

By actually using the concepts of the scientific method (experimentation etc), we come up with things that are true (as far as we can measure them) rather than stories we make up that sound good.
"Gravity is what requires us to eat, it pulls the food out of our bodies"... The fact that this explanation was considered shows that the concept of digestion wasn't understood. There is nothing wrong with that. The problem is that this theory is easily tested, by laying down or standing on your head for a day and seeing if you get hungry.

Radiation hazards are discussed on pages 10, 13, 81, 83, 95, and 114-120 of _The Case for Mars_. The fuel production processes are detailed starting on page 148, and end on page 156 with a mention of the power requirements (300 watts, which makes the "nuclear reactor" just another RTG) for a sample return mission. The mass requirements of a fission generator are on page 205. This is just the discussion in the popular non-fiction book; don't be too surprised if the actual studies (the first study by JPL claimed the human mission would be doable for $50 billion; more recent studies by NASA claim $33e9 + $7e9 per mission, and the ESA thinks they could do it for under $22e9 + $6e9 per mission.)
If you have some specific concerns with the proposals, it would be more credible of you to bring them up rather than pretend that these problems haven't been considered at all. Do you really think that a NASA engineer might read your post and exclaim "There's radiation in space! Why didn't I think about that!?"

Ancient Flying Machines in India (Score:5, Interesting)
According to ancient Indian texts, the people had flying machines which were called "Vimanas." The ancient Indian epic describes a Vimana as a double-deck, circular aircraft with portholes and a dome, much as we would imagine a flying saucer.
It flew with the "speed of the wind" and gave forth a "melodious sound." There were at least four different types of Vimanas; some saucer shaped, others like long cylinders ("cigar shaped airships"). The ancient Indian texts on Vimanas are so numerous, it would take volumes to relate what they had to say. The ancient Indians, who manufactured these ships themselves, wrote entire flight manuals on the control of the various types of Vimanas, many of which are still in existence, and some have even been translated into English.
The Samara Sutradhara is a scientific treatise dealing with every possible angle of air travel in a Vimana. There are 230 stanzas dealing with the construction, take-off, cruising for thousand of miles, normal and forced landings, and even possible collisions with birds. In 1875, the Vaimanika Sastra, a fourth century B.C. text written by Bharadvajy the Wise, using even older texts as his source, was rediscovered in a temple in India. It dealt with the operation of Vimanas and included information on the steering, precautions for long flights, protection of the airships from storms and lightening and how to switch the drive to "solar energy" from a free energy source which sounds like "anti-gravity."
The Vaimanika Sastra (or Vymaanika-Shaastra) has eight chapters with diagrams, describing three types of aircraft, including apparatuses that could neither catch on fire nor break. It also mentions 31 essential parts of these vehicles and 16 materials from which they are constructed, which absorb light and heat; for which reason they were considered suitable for the construction of Vimanas. This document has been translated into English and is available by writing the publisher: VYMAANIDASHAASTRA AERONAUTICS by Maharishi Bharadwaaja, translated into English and edited, printed and published by Mr. G. R. Josyer, Mysore, India, 1979 (sorry, no street address). Mr. Josyer is the director of the International Academy of Sanskrit Investigation located in Mysore.
