Research done in regard to mars pressure issue:

Read every publicly available document on the MSL pressure measurement system design and test methods
Read at least one revision of most of the design related documents for MSL
Read most of the pressure related documents for all other Mars spacecraft
Wrote software to decode seven different versions of MSL raw telemetry data
Tested several of the same type of Barocap pressure sensors used on MSL in a pressure vessel at multiple different pressures

Before finding the units error, I had used co2 phase state diagrams, diffuse light calculations and parachute decent rates to estimate the pressure to be 10 PSI, and made the website mars10psi.com

Used the 111 page viking calibration notes (handwritten) and sensor voltages from raw telemetry data to get an estimate of about 8.5 PSI

Found the units error of Pa and hPa being used interchangeably in software

Based on all of the above data, and more, I currently assume the atmospheric pressure of Mars to be 9 PSI, instead of 0.09 PSI





Does the ozone layer protect us from cosmic rays, or is the ozone layer where oxygen turns to ozone as it protects us from cosmic rays?

What does breathing in 5% of LD50 of copper vapor from a plasma torch do to Covid-19?

Google Mars doesn't show any clouds in the sky on Mars. Google Earth doesn't show any clouds on Earth either.

Physics is a set of polynomial and exponential approximations, that each work well in their limited scope, to give similar numerical results as the actual equations we do not yet know.

At what rate does the cadmium of newer solar cells sublime and re-condense on to optics of satellites?

On the F-35, what electrical system components are shared by the pilots oxygen system and navigation lights?

If you use a PRBS 2^7-1 as the clock for an 8 bit counter, does the high bit have a 50% duty cycle? What happens when you use the high bit as a reference clock for a scope?

I had been sailing more than a hundred times at sunset before I saw the green flash (High Roler, 77090). You will know you have seen it when you have; just like to first understand recursion, you must first understand recursion.

If we assume Venus is 45 km larger in diameter (Radar Aliasing Distance) and has 14.0 PSI atmospheric pressure, the surface temperature comes out to about 80F.

Many weather balloons using radiosondes no longer report actual pressure data, but instead report estimated pressure based on GPS position, temperature and humidity. (Vaisala Radiosonde RS41-SG is one example.)

"Johnny had three truckloads of plutonium. He used three of them to power New York for a year. How much Plutonium did Johnny have left? Four truckloads." -U.S. D.O.E.

The usable energy content of one cubic foot of uranium is approximately the same as contained in 100,000,000 gallons of gasoline, and makes one cubic foot of waste.

In the 2011 magnitude 9.0 earthquake near Japan, and the resulting tsunami, 14308 people drowned, 667 were crushed to death, 145 died from burns, 6156 people were injured by various means, and one person was hurt by falling glass in the meltdown of a nuclear reactor.


When does SHA256 (ivec,block) = ivec?

Note that SHA256 (ivec,block) = SHA256 (ivec,block,block) for example above.         sha256mt.c, sha256inv.cpp, sha256fixedpoints.c, sha256collisions.c

If every person/company mining Bitcoin turned off half of thier computers, all the Bitcoin miners would make twice as much money.

Why 5 rotor drones? What an odd number.
I do not believe in the... See turtle joke on previous page.
I want to go to Mars. So do many others. If I'm correct about the atmospheric pressure, ignoring this will likely maintain the 30% success ratio of missions to Mars. I'm not willing to get on a spacecraft with those odds, but 75%, sure, why not...

What do I want in life? A R30ia or R30ib. Even a broken one.


My very own approximation in a Xilinx 9572XL
Fitting three phase, 6 output, motor control in a Xilinx XC9572XL is annoying.
