BASIC REPORT FOR MARS CORRECT:

ABSTRACT: We present evidence that NASA is seriously understating Martian air pressure. Our 8-year study critiques 1,858 Sols (over 5 terrestrial years, 2.75 Martian years) of highly problematic MSL Rover Environmental Monitoring Station (REMS) weather data, and offers an in depth audit of over 8,311 hourly Viking 1 and 2 weather reports. We discuss analysis of technical papers, NASA documents, and personal interviews of transducer designers. We troubleshoot pressures based on radio occultation/spectroscopy, and the previously accepted small pressure ranges that could be measured by Viking 1 and 2 (18 mbar), Pathfinder and Phoenix (12 mbar), and MSL (11.5 mbar - altered to 14 mbar in 2017). For MSL there were several pressures published at or slightly above the initial advertised upper range of the pressure sensor. Indeed, from August 30 to September 5, 2012 pressures initially published were from 737 mbar to 747 mbar – two orders of magnitude high – only to be retracted. We challenged them all and NASA revised them down, however 8 years into this audit it has come to our attention that of two pressure sensors ordered by NASA for Mars Pathfinder, one of them (Tavis Dash No. 1) could in fact measure up to 1,034 mbar. Further, for the MSL according to an Abstract to the American Geophysical Union for the Fall 2012 meeting, The Finnish Meteorological Institute (FMI) states of their MSL (and Phoenix) Vaisala transducers, “The pressure device measurement range is 0 – 1025 hPa in temperature range of -45°C – 55°C, but its calibration is optimized for the Martian pressure range of 4 – 12 hPa..” So while we originally thought that of the five landers on Mars that had meteorological suites, none of them could measure Earth-like pressures, in fact, assuming that the higher pressure sensor Pathfinder Tavis Dash 1 (0-15 PSIA/1,034 mbar) was sent rather than Tavis Dash 2 (0-0.174 PSIA/12 mbar), three landers were actually equipped to get the job done, but the public was largely kept in the dark about it. All 19 low uv values were removed when we asked about them, although they eventually restored 12 of them. REMS always-sunny opacity reports were contradicted by Mars Reconnaissance Orbiter photos. Why REMS Team data was so wrong is a matter of speculation beyond the basic thrust of this report, but we demonstrate that their weather data was regularly revised after they studied critiques in working versions of this report and on our websites at http://marscorrect.com and http://davidaroffman.com.

We note that Vikings and MSL showed consistent timing of daily pressure spikes which we link to how gas pressure in a sealed container would vary with Absolute temperature, to heating by radioisotope thermoelectric generators (RTGs), and to dust clots at air access tubes and dust filters. Pathfinder, Phoenix and MSL wind measurement failed. Phoenix and MSL pressure transducer design problems included confusion about dust filter location, and lack of information about nearby heat sources due to International Traffic and Arms Regulations (ITAR). NASA Ames could not replicate dust devils at 10 mbar. Rapidly filled MER Spirit tracks required wind speeds of 80 mph at the assumed low pressures. These winds were never recorded on Mars. Nor could NASA explain drifting Barchan sand dunes. Based on the above and dust devils on Arsia Mons to altitudes of 17 km above areoid (Martian equivalent of sea level), spiral storms with 10 km eye-walls above Arsia Mons and similar storms above Olympus Mons (over 21 km high), dust storm opacity, snow at Phoenix, excessive aero braking, liquid water running on the surface in numerous locations at Recurring Slope Lineae (RSL) and stratus clouds 13 km above areoid, we argue for an average pressure at areoid of ~511 mbar rather than the accepted 6.1 mbar. This pressure grows to 1,050 mbar in the Hellas Basin.

 

 

ABSTRACT FOR PART 2 by Barry S. Roffman (November 6, 2012 - This needs to be updated): After a cursory review of the Viking Project Data it became apparent that an extensive audit was imperative. The Viking Project Data did not seem to explain weather phenomena (spiral clouds over Arsia Mons, dust devils, etc.) clearly seen on Mars. A general discussion of the problems is offered in the Basic Report by David Roffman. The data audit results are presented in seven Annexes. The Viking Project data divides every Martian day into 25 time-bins (hours), each ~59 minutes long. Annex A (Viking 1 sols 1 to 350) and Annex B (Viking 2 sols 156 to 361) emphasize how pressures change during morning time-bins that correspond to 0630 to 0830. A simple formula, Pressure predicted = (6.51 mbar*255.77 K)/Temperature K measured, was often correct for 0730. Annex C examines how often the pressure sensor did not work (stuck or no pressures) between Viking 2 sols 639 and 799. Annex D examines the percent differences between hourly predictions and reported pressures for Viking 1 from sols 1 to 350. Annex E focuses on predictions and reported pressures for the 0.3 (0730) and .34 (0830) time-bins. Annex F maps out the best and worst prediction times each day, clearly proving the influence of the RTG heaters on hourly pressure reports. Annex G shows what went wrong in the transducer selection and testing process. These Annexes provide hard evidence that the Tavis pressure transducers used for the Vikings (and Pathfinder) likely jammed with dust during the landing process. The meaning of this is that it is doubtful that they ever measured ambient pressure conditions of Mars.  There is evidence that all subsequent attempts to measure pressure were colored by the reported Viking results. Problems with Phoenix pressures based on a Vaisala transducer are discussed in the Basic Report. Annex I discusses the the initial pressure results in from the MSL with a focus on its sols 15 to 87 (Ls 158.8 to 199.8) which occurred between August 22 and November 3, 2012.

Now I'm a University of Florida Gator. MSL data is as easy to consume as was Viking, Pathfinder and Phoenix data. The truth isn't just out there. It's on this web site. For a PowerPoint about how we eat MSL data, see the link below.
