The Mars Science Laboratory (MSL) Rover Curiosity has now been on the Martian surface since August 6, 2012. On June 24, 2012 it reached its 669th sol (Martian day) on Mars, thus completing one Martian year. Its much revised Martian surface pressure record, when combined with Viking1, Viking 2 and Phoenix is shown on Figure 1:
Original data for its Sol 1 at Ls (Solar Longitude) 150 had been pulled down by the Rover Environmental Monitoring Station (REMS) Team working for NASA and the Jet Propulsion Lab (JPL), however their regular reports began with Sol 10 and, at this time of this article, they continue until at least Sol 1355 on May 29, 2016. The record keeping job done by the REMS Team and JPL, along with their Ashima Research associates was, at least for the first terrestrial year, simply horrible. Ashima finally took down its webs site. Both sites were full of obvious clerical errors, but also marked by what looks like political editing – something that has no place in science. As we passed 2 Martian years/4 terrestrial years on Mars the possible political editing continues and is color-documented on the spreadsheets given on the links above. Often it appears that NASA checks what is published on the spreadsheets, which amounts to an unpaid for audit of MSL weather data – and then they make the corrections that we propose or highlight as problems (with the very major exception of raising the pressures to an amount about 85 times higher than what they publish). Thus when we pointed out that it’s hard to accept low ultraviolet radiation given their assertion that Mars has very low pressure, that no days for MSL were listed as anything but sunny, and that Mars has no known ozone layer, by February 25, 2016 they simply removed 19 sols with low UV. Previously they had removed all wind data after we pointed out that for 9 months it never ever changed according to their reports, and they altered they length of daylight for every sol to what my son calculated at http://davidaroffman.com/photo4_26.html.
HOW CAN NASA FIX THE PERCEIVED CREDIBILITY PROBLEM? That’s easy. Offer my son, David, Mars-related employment where he is allowed to help fix data problems without regard to politics. NASA can also allow me to join the Mars team on an advisory basis. David, has his PhD in physics and is current doing his post doc at Yale. I am happily retired and living in Cape Canaveral, and I don’t need a salary. I do Mars research just for the joy of learning. All I ask for is travel expenses when appropriate.
The Viking 1 and 2 data is taken directly from Professor James Tillman and his Viking Computer Facility. See http://www-k12.atmos.washington.edu/k12/resources/mars_data-information/data.html. The Phoenix data is from Nelli, S.M., Renno, N. O., Feldman, W. C., Murphy, J. R., & Kahre, M. A.
