Water on Mars

Subsurface water in early Mars

Article in the Nov 2, 2011 online edition of the journal Nature (Nov 3rd in hardcopy).  Recently discovered clay minerals widespread in Mars's Noachian terrains point to long duration interactions between water and rock during Mars early history. However, the article makes the point that since the Noachian rock record is dominated by a history of subsurface waters, Mars was most likely a cold arid planet for the last 4 billion years with short periods of surface water.

Evidence for a deep Martian ocean

Review in the June 13, 2010 issue of the journal Nature Geoscience.  Researchers argue that evidence for a large ancient ocean on Mars is substantiated by river deltas that, they say, mark the vast ancient Martian sea level.

GALACTIC COSMIC RAYS

Does the Space Environment Affect the Ecosphere?

An informative article in the Sept 6, 2011 edition of the journal EOS transactions of the American Geophysical Union.  The sun is known to create dangerous CME's of it's own. However, it also creates a protective "bubble" (the heliosphere) by way of radiation pressure of the solar wind.  We rely on this protective bubble to shield us against the even more deadly GCRs (galactic cosmic rays) which can be of extremely high (billions of electron-volts) energy. The solar wind pressure has been declining and this allows for greater potential penetration of GCRs into the Earth's atmosphere. The article goes on to say the geological records of the radioisotope beryllium-10 taken from polar ice core samples has shown that the GCR intensities in Earth's history have been exceedingly variable.  The conjecture is that the past increases in GCRs reaching the Earth may in fact have aided in stimulating evolution by increasing the rate of cell mutation!

Effects of Solar Storms on Earth

Predicting Radiation Dose on Aircraft from SEPs

Article in Vol 8, Issue 3, 2011 (p 8) of Space Weather, a quaterly journal of the American Geophysical Union describing a recent half-day session held during the Japan Geoscience Union 2011 International Symposium on May 24th, 2011.  A future early warning system for aircraft was proposed. It was tentatively called the Warning System of Aviation Exposure to SEP (WASAVIES):  It's purpose would be to automatically calculate radiation dosages along an aviation route for any flight operated during a particular prediction interval. This is particularly useful for transpolar flights such as between Tokyo and New York or between San Francisco and Paris.

Deleterious Effects of Space Storms on Earth
Article by Michael Brooks in March 21, 2009 edition of New Scientist magazine warning of a complete shutdown of all electrically reliant technology due to a massive DC current overloading of the power grid if ever a major solar storm (but only a storm possessing a southward pointing magnetic field whose magnetic field lines could reconnect with the Earth's) would someday make a direct hit on the Earth.

Space Flight Technology News

Ion engines for space travel
An article in the July 24th, 2009 edition of New Scientist magazine. Ion engines, are less powerful for liftoff but can continue to generate power for long lengths of time. As such, a rocket could potentially reach a higher max speed than with a conventional chemical engine.
Shortage of Plutonium-238 for NASA's missions

An interesting article in Jan 2011 issue of Physics Today magazine summaries of the issues surrounding powering NASA's planetary science missiion. The current supply of Pu-238 is falling behind NASA's needs to supply power to spacecraft in distant missions where the sunlight is too dim. There is only enough left to power two of the four NASA planetary misssionss due for launch by 2020.  The current technology, Pu-238-powered radioisotope thermoelectric generators (RTGs) have no moving parts. They convert heat generated by the decay of Pu-238 directly into electricity but with only a 6% efficiency.  However, newer techology Advanced Sterling Radioisotope Generators (ASRGs) have moving parts operate with 29% efficiency and thus require far less Plutonium to accomplish the same task.

Article (pages 419-422 ) in May 21, 2009 edition of the journal, Nature. Researchers claim that the Earth could not have been completely sterilized even by the tremendous onslaught of asteroids during the period of known as the "late heavy bombardment." They conclude that hyperthermophilic microbes could have survived the intense heat and be the ancestors of any present day life on Earth and elsewhere.
