Enzmann thought a crew of 200 would be about right, with plenty of room for growth to an optimum population of 2000, a figure that balances against the closed-cycle ecology of the ship. Andy, if you consider the bremsstrahlung losses, D-D come out as the most difficult of only three realistic fusion reactions (see https://en. The proposed method of tank construction would be to expand a plastic balloon in space and coat it with metal.

The spacecraft would be modular, and the main living area would be three identical 300 feet (91 m) wide and long cylindrical modules. Because Stine thought in terms of ships traveling together, his ultimate expedition would be about the size of a small city of 20,000 or so dispersed through ten starships. A: As I said earlier, there is still a year and a half’s worth of data in the pipeline to analyze to identify candidate planets, so there are still discoveries to be made. In conclusion, we are simply the custodians of the Archive, but FREA, in truth, is the history and future of humanity. Eniac, deuterium was the fuel of choice because it could be fused without requiring a fission primary to make enough neutrons to get the “dry” fusion reaction started.A possible explanation is the lack of fuel tanks – this may decrease the dry mass fraction considerably. Doc E kept silent for over 40 years, although he was able to publish descriptions of vastly less efficient but nevertheless workable interstellar drives in those years.

What I’m doing here is looking at Stine’s use of Enzmann as reflected in his Analog article, in which he foresees fleets of Enzmann starships dispatched in a regular pattern of interstellar exploration. Have you ever dreamed of soaring through the cosmos, leaving Earth’s gravitational pull behind as you gallivant between galaxies? Adam Crowl, working with Kelvin Long and Richard Obousy, has produced an excellent overview of the Enzmann design that appeared in the Journal of the British Interplanetary Society last year (reference below). Enzmann’s innovative design for a relativistic interstellar ship is nothing short of revolutionary, combining cutting-edge scientific concepts with a hefty dose of wishful thinking. This book concludes by noting that the construction and launch of Echolance fleets can be accomplished without major technological breakthroughs, at surprisingly affordable cost, in a relatively short time, and with beneficial consequences for humans who remain on the Earth, as well as for those who open up the cornucopia of interstellar space.As the spaceship zips through the cosmos, passengers can sit back, relax, and marvel at the stunning intergalactic views.

A common feature was that the crew area was replicated 3 times for redundancy, and a common core pillar ran the length of the spacecraft and through the center of each habitation unit. NASA officials announced Wednesday, May 15, that the Kepler space telescope — the agency’s primary instrument for detecting planets beyond our solar system — had suffered a critical failure and could soon be shut down permanently.
