Will NASA Ever Send Astronauts To Pluto?

Posted by in category: space travel

With its nitrogen-dominated atmosphere and water-rich icy surface, Pluto seems much more hospitable than even the most sanguine planetary scientists would have wagered a decade ago. But could it ever play host to an Antarctic-styled research station?

That is, as a base to routinely house researcher/astronauts out to give humans a foothold in the outer reaches of our solar system?

“The notion of a Pluto base figures prominently in the anime ‘Star Blazers’ from my childhood, so it’d be wonderful if there were a good reason for it,” said Gerard van Belle, a research astronomer at Lowell Observatory in Flagstaff, Az., where Clyde Tombaugh discovered the diminutive dwarf planet some 85 years ago.

David Eagleman: Can a Computer Simulate Consciousness?

Posted by in categories: computing, information science, neuroscience, space travel

Yes, conceivably. And if/when we achieve the levels of technology necessary for simulation, the universe will become our playground. Eagleman’s latest book is “The Brain: The Story of You” (http://goo.gl/2IgDRb).

‘Electric Sails’ Could Propel Superfast Spacecraft

Posted by in categories: particle physics, robotics/AI, space travel

SANTA CLARA, California — Robotic spacecraft may ride the solar wind toward interstellar space at unprecedented speeds a decade or so from now.

Researchers are developing an “electric sail” (e-sail) propulsion system that would harness the solar wind, the stream of protons, electrons and other charged particles that flows outward from the sun at more than 1 million mph (1.6 million kilometers per hour).

“It looks really, really promising for ultra-deep-space exploration,” Les Johnson, of NASA’s Marshall Space Flight Center in Huntsville, Alabama, said of the e-sail concept here at the 100-Year Starship Symposium on Oct. 30. [Superfast Spacecraft Propulsion Concepts (Images)].

Theory of a Mach Effect Thruster II

Posted by in categories: energy, information science, quantum physics, space travel

ABSTRACT

According to Einstein, General Relativity contains the essence of Mach’s ideas. Mach’s principle can be summarized by stating that the inertia of a body is determined by the rest of the mass-energy content of the universe. Inertia here arises from mass-energy there. The latter, was a statement made by John Wheeler in his 1995 book, Gravitation and Inertia, coauthored by Ciufolini. Einstein believed that to be fully Machian, gravity would need a radiative component, an action-at-a-dis- tance character, so that gravitational influences on a body from far away could be felt immediately. In 1960’s, Hoyle and Narlikar (HN) developed such a theory which was a gravitational version of the Absorber theory derived by Wheeler-Feynman for classical electrodynamics and later expanded upon by Davies and Narlikar for quantum electrodynamics. The HN-field equation has the same type of mass fluctuation terms as in the Woodward Mach effect thruster theory. The force equation, used to predict the thrust in our device, can be derived from the mass fluctuation. We outline a new method for deriving the force equation. We present new experimental tests of the thruster to show that the thrust seen in our device is not due to either heating or Dean Drive effects. Successful replications have been performed by groups in Austria and Canada, but their work is still pending in the peer review literature.

Theory of a Mach Effect Thruster I

Posted by in categories: energy, information science, materials, space travel

ABSTRACT

The Mach Effect Thruster (MET) is a propellant―less space drive which uses Mach’s principle to produce thrust in an accelerating material which is undergoing mass―energy fluctuations, [1] –[3]. Mach’s principle is a statement that the inertia of a body is the result of the gravitational interaction of the body with the rest of the mass-energy in the universe. The MET device uses electric power of 100 — 200 Watts to operate. The thrust produced by these devices, at the present time, are small on the order of a few micro-Newtons. We give a physical description of the MET device and apparatus for measuring thrusts. Next we explain the basic theory behind the device which involves gravitation and advanced waves to incorporate instantaneous action at a distance. The advanced wave concept is a means to conserve momentum of the system with the universe. There is no momentun violation in this theory. We briefly review absorber theory by summarizing Dirac, Wheeler-Feynman and Hoyle-Narlikar (HN). We show how Woodward’s mass fluctuation formula can be derived from first principles using the HN-theory which is a fully Machian version of Einstein’s relativity. HN-theory reduces to Einstein’s field equations in the limit of smooth fluid distribution of matter and a simple coordinate transformation.

Why NASA’s EmDrive Might Be the Most Exciting Breakthrough in Tech Right Now

Posted by in categories: energy, physics, space travel

Earthlings, meet the EmDrive, the rocket of the future.

Allegedly, Eagleworks Labs at NASA’s Johnson Space Center has defied a Newtonian law of physics and created a futuristic warp drive. If it’s real, it could be the most exciting breakthrough in space-travel technology to date: an engine that gets from point A to point B without using any fuel — and does it crazy fast.

Despite months of skepticism, our nation’s aerospace agency wants you to believe its latest findings are legit. Recent studies purportedly prove the EmDrive’s authenticity. Even NASA researcher Paul March hopped on a (non-NASA-affiliated) spaceflight forum to chat about the agency’s findings.

In a new round of testing, NASA confirms yet again that the ‘impossible’ EMdrive thruster works

Posted by in categories: physics, space travel

Engineer Roger Shawyer’s controversial EM Drive thruster jets back into relevancy this week, as a team of researchers at NASA’s Eagleworks Laboratories recently completed yet another round of testing on the seemingly impossible tech. Though no official peer-reviewed lab paper has been published yet, and NASA institutes strict press release restrictions on the Eagleworks lab these days, engineer Paul March took to the NASA Spaceflight forum to explain the group’s findings. In essence, by utilizing an improved experimental procedure, the team managed to mitigate some of the errors from prior tests — yet still found signals of unexplained thrust.

Isaac Newton should be sweating.

Flying in the face of traditional laws of physics, the EM Drive makes use of a magnetron and microwaves to create a propellantless propulsion system. By pushing microwaves into a closed, truncated cone and back towards the small end of said cone, the drive creates the momentum and force necessary to propel a craft forward. Because the system is a reactionless drive, it goes against humankind’s fundamental comprehension of physics, hence its controversial nature.
