Been There, Done That on Earth, What Planet's Next? But nobody is going to walk on Mars if NASA ignores the data on this web site.
I am now certain that we have the proof required to show that pressures measured by our Mars landers were all pertaining only to small amounts of air trapped behind the dust clots, and that the pressures measured varied almost precisely in accordance with Gay-Lussac's Pressure Law. It describes how pressures vary directly with temperature for a gas in a closed container. The ambient pressure on Mars was never measured by any of the four landers sent to do just that because nobody thought about dust filters clogging on landing, or about a way to change those filters and clean the air access tubes. This means that almost everything ever written about Martian air pressure since the mid 1960's is wrong (with earlier, higher pressures being correct), and it probably explains at least some of the crashed or lost landers that were sent to Mars after the flawed Viking data was accepted and made the Gospel for all spacecraft lander design. This web site will lay out the results of an extensive audit of all Viking data. Failure by NASA to look at the evidence here will likely result in future failures and delays for our eventual exploration of Mars. It will also result in the waste of hundreds of millions or billions of tax dollars on funds spent to explore Mars. Recently the European Space Agency published a report that concluded, "It seems that previous models have greatly underestimated the quantities of water vapour at heights of 20–50 km, with as much as 10 to 100 times more water than expected at this altitude." This conclusion is fully in line with our findings. The partial pressure implications are more evidence that we are correct about higher than advertised Martian Air Pressure, but we are far from certain that the political mind set controlling planning for Mars Missions is compatible with establishing the true conditions on Mars today.
Education and Goals: I earned my B.S. in Space Physics at Embry-Riddle Aeronautical University (ERAU) in Daytona Beach, Florida. I graduated on December 18, 2011; and I'm currently enrolled in the Physics PhD program at the University of Florida. My goals are as follows:
1. Finish my doctorate in Physics with speciality in High Energy Theory or Experimental Physics at the University of Florida. Sadly, this option is somewhat limited by the fact that there are two physics PhD grads in the U.S. for each physics job open. Many physicists are being recruited out of their field and into Quantitative Finance which I discuss elsewhere in this site.
2. Work on Faster than Light (FTL) mechanisms that relate to General Relativity, and space-time geometry solutions that exhibit time travel. To gain more familiarity with this exotic field I outlined Frontiers in Propulsion Science, a text that was published in February 2009 by the American Institute of Aeronautics and Astronautics.
3. Help facilitate the first manned mission to Mars if NASA ever seriously funds such a project.
Interests : I have an intense interest in space flight well beyond Earth orbit. In a sense, I have already orbited the earth myself, visiting Canada, Mexico, England, Spain, France, Italy, Vatican City, Portugal, Russia, Egypt, China, Mongolia, Greece, Cyprus, and Israel. I once travelled from Miami to Egypt via cruise ship, train, car ferry, and bus. On a trip around the world in 2007, my passage from Beijing through Ulan Bator in Mongolia and on to Moscow was via Trans Siberian Railway. Many of my trips are summarized on the left side of the first picture below.
