Enzmann Echolance: Reach For The Stars

Product Information

A few tons of food and O2 per crew member/year might be an easier way to go than full recycling, if food can be made shelf stable for a century or more. Last week a reaction wheel on NASA’s Kepler spacecraft failed, putting the future of the extrasolar planet hunting spacecraft into jeopardy.

Lithium fissions easily to tritium and helium 3 under fusion conditions, if I am not mistaken, so the two are pretty much interchangeable.

Enzmann of the Raytheon Corporation proposed an interstellar ark driven by eight nuclear pulse rockets. If you'd like to submit a comment for possible publication on Centauri Dreams, I will be glad to consider it. What’s important is that most of the candidates are too faint for atmospheric characterization or for mass (and thus density) determinations (except for masses that can be determined (well) for some multiple systems from transit timing variations and for fewer systems from ellipsoidal variations and doppler boosting (not so well for these techniques)).

Jeff Foust reports on efforts to rescue or repurpose Kepler, and why, even with the failure, the spacecraft’s exoplanet discoveries will continue. It lived the length of its prime mission, and was extremely successful during that time at achieving this goal. They can even take selfies with passing stars, although the nearest Wi-Fi hotspot might be a few light-years away. The Empire State Building, New York’s iconic symbol, would fit lengthwise easily enough with just its top tower sticking out the end. But IIRC, the 2,xxx planet “candidates” cannot be confirmed by Kepler…it can’t distinguish those from an in-line eclipsing binary.

But take heart — a vast amount of data already gathered by Kepler remains to be studied, meaning we’ll be getting Kepler discoveries for some time to come. I mentioned at the outset of this series on 1970s starship projects that among some designers, at least, it was a time of immense optimism.

Nuclear pulse propulsion would detonate a fission bomb behind the vehicle to drive it forward, using enormous shock absorbers to cushion the craft. Andy, if you consider the bremsstrahlung losses, D-D come out as the most difficult of only three realistic fusion reactions (see https://en. Overall specifications have varied somewhat, but the design has nuclear pulse engines at the rear, then cylinders for human habitation, then closer the front a large ball of fuel. We don’t share your credit card details with third-party sellers, and we don’t sell your information to others.

In a conversation with Stanford News Service, Hubbard explained the possible ways that NASA could bring the spacecraft back online, and what planet hunters will do next if that’s not possible.

I imagine it was Dyson’s starship that fired the imagination of Robert Duncan-Enzmann, then at Raytheon Corporation, leading to a modified and extended Orion that Stine would use in his article. A voyage aboard an Enzmann Starship is no less than a leap into the cosmos, daring to travel the interstellar distances that lay beyond our solar system’s boundaries.

In any case, he was a rocket man, and it was perhaps inevitable that it would be Project Orion that drew his attention.I see Bob Enzmann's work as being one of the few things that the public can latch onto that will enable everyone to have a greater vision of humanity, a greater chance of survival for humanity, and something that will truly begin to lift us up and become an advanced civilization. The Echolance is designed to travel at relativistic speeds, which means that the faster it goes, the more time slows down for those on board. With a little luck and a lot of scientific breakthroughs, we might just find ourselves gallivanting between galaxies, sipping on cosmic cocktails, and laughing in the face of Father Time. Stine points out that a Saturn V without the Apollo escape tower would lie sideways inside this cylinder, which contains nearly a half-million cubic feet of living space.
