The Nuclear Heart of Planet Earth![]() What would we find if we were to dig a hole all the way down to the centre of the Earth? According to high school science books we would discover a liquid iron alloy core and a smaller solid inner core at the center. For ten years, geophysicist J. Marvin Herndon has presented increasingly persuasive evidence that at the very centre of the Earth, within the inner core, there exists a five mile in diameter sphere of uranium which acts as a natural nuclear reactor. In this extended interview Wayne Smith talks with Dr Herndon about this theory and its implications for planetary science. Yuri's Night 2003 ![]() For the third time, space enthusiasts around the globe will gather on April 12 to celebrate the anniversary of Yuri Gagarin's flight into space. Major Yuri Gagarin became the world's first space traveler when his spacecraft, Vostok 1, was launched into orbit on April 12, 1961. |
The Universal Reusable First Stage: The Next 'Stage' In Space Transport![]() The Space Race of the 1960s did not allow the time needed to develop reusable Space transportation systems.

ESA To Sign Contract With DLR For Columbus Control Centre ![]() On 31 March at Oberpfaffenhofen, near Munich, Germany, ESA Director of Human Spaceflight Mr J�rg Feustel-B�echl will sign a EUR 37.7M contract with DLR, the German national agency for aerospace research and spaceflight, to develop the Columbus Control Centre for the European Columbus laboratory on the International Space Station (ISS). |
Underwater Sensor System Could Protect Reservoirs, Drinking Water![]() A sensor system that can autonomously, continuously and in real-time monitor streams, lakes, ocean bays and other bodies of liquid may help solve problems for environmentalists, manufacturers and those in charge of homeland security, according to Penn State engineers. SES Americom To Provide Satellite Capacity To Echostar ![]() SES Americom, Inc., an SES GLOBAL Company and U.S.-based satellite operator, announced today a multi-year service agreement to provide satellite capacity to EchoStar Communications Corporation on Americom's AMC-15 satellite, a new satellite currently under construction. |
Astronomers Deal Blow To Quantum Theories Of Time, Space, Gravity![]() For the second time in as many months, images gathered by the Hubble Space Telescope (HST) are raising questions about the structures of time and gravity, and the fabric of space. America Not Prepared for Bio-Terror ![]() One would think, after the many months of debate and evaluation by the experts, that all of the major concerns about the United States smallpox protection plan presently being implemented, would have been resolved. However, at last count seven weeks into stage one (of three stages), only about 17,000 individuals (3.7 percent of the goal) have been vaccinated writes Saul B. Wilen. |
ESA Studies Missions to Safeguard the Earth![]() In July 2002 the general studies programme of the European Space Agency (ESA) provided funding for preliminary studies on six space missions that could make significant contributions to our knowledge of NEOs. SETI@home Completes Stellar Countdown ![]() The SETI@home team has completed a successful run at the Arecibo radio telescope in Puerto Rico re-observing promising radio sources in the search for extraterrestrial intelligence.
