The Genesis spacecraft continues its mission collecting solar wind material expelled from the Sun. Telemetry from the Genesis spacecraft indicates that all spacecraft subsystems are reporting nominal operation.
Skin And Flips. Greenbelt - Nov 20, 2003
Research with the Solar and Heliospheric Observatory (SOHO) spacecraft has revealed the process that may implement the reversal in the direction of the Sun's magnetic field that is known to occur every 11 years. This newly recognized factor in the Sun's magnetic flipping is the cumulative effect of more than a thousand huge eruptions called Coronal Mass Ejections (CMEs). (Note that Kent Hovind does not believe a magnetic field can reverse especially on earth)
Sun An Iron-Rich Powerhouse. Rolla - Nov 18, 2003
The spate of solar storms to hit Earth in recent days may be caused by the sun's iron-rich interior, says a UMR researcher who theorizes that the sun's core is made of iron rather than hydrogen.
With Intense Activity. Boulder - Oct 24, 2003
Forecasters at the NOAA Space Environment Center in Boulder, Colo., observed two dynamic areas of the sun, one of which has produced a coronal mass ejection, or CME, Wednesday morning at 3 a.m. EDT that appears to be Earth-directed. The forecasters are predicting a strong geomagnetic storm, G-3 on the NOAA Space Weather Scales, that should reach Earth on Friday, October 24.
From The Galactic Deep. Huntsville - Sep 15, 2003
On August 24, 1998, there was an explosion on the sun as powerful as a hundred million hydrogen bombs. Earth-orbiting satellites registered a surge of x-rays. Minutes later they were pelted by fast-moving solar protons. Our planet's magnetic field recoiled from the onslaught, and ham radio operators experienced a strong shortwave blackout.

Factory On Sun Yields Clues To Solar Explosions. Greenbelt - Sep 04,
The best look yet at how a solar explosion becomes an antimatter factory gave unexpected insights into how the tremendous explosions work. The observation may upset theories about how the explosions, called solar flares, create and destroy antimatter. It also gave surprising details about how they blast subatomic particles to almost the speed of light.

Despite evidence from two space probes in the 1990s, radar astronomers say they can find no signs of thick ice at the moon's poles. If there is water at the lunar poles, the researchers say, it is widely scattered and permanently frozen inside the dust layers, something akin to terrestrial permafrost.

Stream of radon There should be plenty of water on Mars. Water vapour has already been detected in the planet's atmosphere, and ice on the surface at the poles. But much of the water may be buried underground. Locating this hidden store is not easy, but radon could be the answer. This gas, produced by radioactive decay, is usually trapped in minerals. But the presence of water or ice allows it to seep up to the surface, providing a wafting signpost. See http://www.newscientist.com/news/news.jsp?id=ns99993968

New Surprises from Mysterious Pluto Pluto, the most distant of the nine planets in our solar system, has piqued the curiosity of astronomers once again. It seems the planet's atmosphere is expanding as it travels away from the sun, rather than contracting as expected.

Stellar Occultations Reveal Drastic Expansion Of Pluto's Atmosphere. Paris - Jul 10, 2003 - Moving on its eccentric orbit, Pluto is presently receding from the Sun; between 1979 and 1999 it was inside Neptune's orbit, but since then it has again been the planet most distant from the Sun. As it moves outward, the amount of solar energy that reaches its surface decreases, so its surface is expected to cool. See http://www.spacedaily.com/news/outerplanets-03i.html
Astronomers Discover Icy World Far Past Pluto: Astronomers have discovered the largest object in the solar system since Pluto was identified more than 70 years ago. The object, dubbed Quaoar (pronounced "kwa-whar") by its discoverers, is approximately half Pluto's size and nearly four billion miles away from Earth.
Do Pluto's Other Children Hide In The Shadow Of Charon: Boulder - Feb 25, 2003 - Pluto has only one known satellite - Charon - discovered in 1978 by American astronomer James Christy. At slightly more than half the diameter of Pluto, Charon's 1,200-kilometer diameter makes it the undisputed "relative size" king of solar system satellites.

The Kuipers Beckon As Pluto Mission Funded: Sacramento - Mar 03, 2003 - After years of uncertainty, the strange "Pluto War" over whether to launch a Pluto flyby spacecraft in the near future is finally almost completely over - and Pluto won. NASA, Congress and the White House finally agreed that they do want an early Pluto probe rather than waiting years for as yet untested nuclear electric propulsion system to be developed and flight tested enough for dispatch to Pluto and out in the Kuiper belt beyond.

UK Scientists All
Set For New Year Encounter With A Comet. London - Dec 17, 2003
On January 2nd 2004 the NASA space mission, Stardust, will fly through comet Wild 2, capturing interstellar particles and dust and returning them to Earth in 2006. Space scientists from the Open University and University of Kent have developed one of the instruments which will help tell us more about comets and the evolution of our own solar system and, critical for Stardust, its survival in the close fly-by of the comet.
Use Radar To Detect Asteroid Force. Pasadena - Dec 08, 2003
NASA scientists have for the first time detected a tiny but theoretically important force acting on asteroids by measuring an extremely subtle change in a near-Earth asteroid's orbital path.
Pinpoints Where the Wild Thing is. Pasadena - Dec 02, 2003
Forty-nine days before its historic rendezvous with a comet, NASA's Stardust spacecraft successfully photographed its quarry, comet Wild 2 (pronounced Vilt-2), from 25 million kilometers (15.5 million miles) away. The image, the first of many comet portraits it will take over the next four weeks, will aid Stardust's navigators and scientists as they plot their final trajectory toward a Jan. 2, 2004 flyby and collection of samples from Wild 2.
Tale of Asteroid Hermes. Pasadena - Nov 03, 2003
It's dogma now: an asteroid hit Earth 65 million years ago and wiped out the dinosaurs. But in 1980 when scientists Walter and Luis Alvarez first suggested the idea to a gathering at the American Association for Advancement of Sciences, their listeners were skeptical. Asteroids hitting Earth? Wiping out species? It seemed incredible.
Asteroid Is Two Orbiting Objects
An asteroid that has eluded astronomers for decades turns out to be an unusual pair of objects traveling together in space. The asteroid Hermes was rediscovered last week after being lost for 66 years. Now Jean-Luc Margot, a researcher in UCLA's department of Earth and space sciences, has determined that the asteroid is, in fact, two objects orbiting each other. The two objects together would cover an area approximately the size of Disneyland.
QQ47's Potential Earth Impact in 2014 Ruled Out. Pasadena - Sep 03,
Newly discovered asteroid 2003 QQ47 has received considerable media attention over the last few days because it had a small chance of colliding with the Earth in the year 2014 and was rated a "1" on the Torino impact hazard scale, which goes from 0 to 10.
View Of Comets As Pristine Relics Of Solar System Formation Evolves. San Antonio - Aug 11, 2003 - The long-held perspective that comets are pristine remnants from the formation of the solar system has evolved from the prevailing views of 30 years ago, finds planetary scientist Dr. S. Alan Stern in a paper published in the journal Nature. See http://www.spacedaily.com/news/comet-03e.html

Rosetta Retasked For 10 Year Trip To Comet Churyumov-Gerasimenko. Sacramento - Jun 11, 2003 - The European Space Agency's ambitious Rosetta mission to rendezvous with and orbit a comet nucleus for the first time -- and then dispatch a small lander onto its surface -- has just survived the most bizarre crisis imaginable.

Japanese Spacecraft On Four-Year Journey To Bring Home Asteroid Samples. Tokyo (AFP) May 09, 2003 - A Japanese spacecraft blasted off Friday on an ambitious four-and-a-half-year journey to bring asteroid samples back to Earth for the first time. The mid-size solid-fuel M-5 rocket, carrying an unmanned MUSES-C probe, lifted off from the Kagoshima Space Centre in the southern Japanese town of Uchinoura at 1:29 pm (0429 GMT) as scheduled.

Get First Close Look At Stardust
For the first time, scientists have identified and analyzed single grains of silicate stardust in the laboratory. This breakthrough, to be reported in the Feb. 27 issue of Science Express, provides a new way to study the history of the universe. See http://www.sciencedaily.com/releases/2003/02/030228073248.htm
