To Mars In A Month With The Help Of Nuclear Fusion
2013-04-09 19:22:32

Michael Harper for redOrbit.com — Your Universe Online There are many who would like to one day go to Mars. This list of willing candidates likely dries up when asked to dedicate a total of four years to the trip. The Inspiration Mars Foundation, on the other hand, believes they can shoot a couple around the Red Planet and back again in just over 500 days. Now, researchers at the University of Washington aim to make the trip in even less time — somewhere around 30 days, to...

Astronomers Discover Solar Wind Energy Source
2013-03-08 12:36:32

NASA Science Using data from an aging NASA spacecraft, researchers have found signs of an energy source in the solar wind that has caught the attention of fusion researchers. NASA will be able to test the theory later this decade when it sends a new probe into the sun for a closer look. The discovery was made by a group of astronomers trying to solve a decades-old mystery: What heats and accelerates the solar wind? The solar wind is a hot and fast flow of magnetized gas that streams...

Space Dust Likely Culprit Behind Fallen Satellites
2013-02-27 12:00:13

Lee Rannals for redOrbit.com - Your Universe Online According to an aeronautics and astronautics professor at Stanford University, "space dust" is the likely culprit behind why satellites fail. Satellites are threatened by both asteroids and "space junk," which are particles of man-made debris that orbit Earth. However, the threat from these impacts is actually relatively low, and most satellites that have died in space were knocked out by something entirely different. Space dust,...

Densest Artificial Ionospheric Plasma Clouds Produced Using HAARP
2013-02-26 10:34:33

U.S. Naval Research Laboratory U.S. Naval Research Laboratory research physicists and engineers from the Plasma Physics Division, working at the High-frequency Active Auroral Research Program (HAARP) transmitter facility, Gakona, Alaska, successfully produced a sustained high density plasma cloud in Earth's upper atmosphere. "Previous artificial plasma density clouds have lifetimes of only ten minutes or less," said Paul Bernhardt, Ph.D., NRL Space Use and Plasma Section. "This higher...

The results are significant because they can help to improve our understanding of medical conditions, such as thrombosis, aneurysms and arteriosclerosis. The research team is publishing its results in Physical Review Letters and the American Physical Society has highlighted the work on its Physics website, placing it on the Focus List of important physics news. Blood flows differently than water. Anyone who has ever cut themselves knows that blood flows viscously and rather erratically....

Electric rocket engines known as Hall thrusters, which use a super high-velocity stream of ions to propel a spacecraft in space, have been used successfully onboard many missions for half a century. Erosion of the discharge channels walls, however, has limited their application to the inner solar system. A research team at Caltech's Jet Propulsion Laboratory, in Pasadena, Calif., has found a way to effectively control this erosion by shaping the engine's magnetic field in a way that shields...

Hannes Olof Gösta Alfvén (May 30, 1908 - April 2, 1995) was a Swedish plasma physicist born in Norrköping, Sweden. Alfvén received his PhD from the University of Uppsala in 1934. His thesis was titled "Investigations of the Ultra-short Electromagnetic Waves." He was originally trained as an electrical power engineer and later moved on to research and teaching in the fields of plasma physics. Alfvén made many contributions to plasma physics, including theories describing the...

Heliopause -- The heliopause is the boundary where our Sun's solar wind is stopped by the interstellar medium. The solar wind blows a "bubble" in the interstellar medium (the rareified hydrogen and helium gas that permeates the galaxy). The point where the solar wind's strength is no longer great enough to push back the interstellar medium is known as the heliopause, and is often considered to be the outer "border" of the solar system. The distance to the heliopause is not precisely...

Solar Prominence -- Solar prominences are large arch-shaped structures observable in the solar corona. These often have a twist and occasionally become unstable, ejecting plasma and magnetic flux out from the sun. The physics of solar prominence instability is believed to be governed by magnetic forces and magnetic helicity issues. It is thought that instability occurs when a magnetic flux tube becomes excessively twisted. ----- Click here to learn more on this topic from eLibrary:
