Please keep the units straight. The pressure will not be zero either, BTW. All liquids have vapor pressures. Not trying to split hairs either, but vapor pressure is a fact.
I guess I could read the links, but I am concerned they contain more misinformation.
1.00 atmosphere = 33.9 feet of H20 = 29.2 inches of Hg
PARENT THREAD QUOTE " You have water in a sealed syringe. You pull the syringe so that the pressure you're doing is 2 atmospheres (-1 from our atmosphere equals one atmosphere). The volume of water doesn't change because you can't break cohesion, what's the pressure of the water inside of the syringe?"
What is the temperature of the water? It will boil at 70 F, so it will not be zero. A quick calculation shows the pressure will be less than one inch of Hg. I am not sure if there is still hope that the pressure in the syringe will go to negative anything. By definition a perfect vacuum is zero [IOW -zero inches of Hg or zero inches of H20]. No such animal as negative atmospheric pressure. Achieving -1 degree Kelvin is a similar effort in futility.
Take all the water out of a real life syringe, collapse it, seal it, and it and pull it to its end, the pressure will approach zero.
Also be advised Wikipedia is a community effort - Garbage in Garbage out. Read their disclaimer. The transpiration definition appears accurate.
In summary, zero in any unit is the lowest attainable pressure. Tall plants survive due the nature of the strong water to water molecule bonds [IE, very small capillaries and Transpiration]. Focusing on the very small nature of the structures in the [tree if you will] plant account for their ability to survive.
Part of the previous post is quoted below. What is described is lower pressure. Saying negative pressure is ambiguous and confusing.
IE, the plunger example is reducing the pressure. The pressure will approach zero, but never a negative number. It is physically impossible.
Keep in mind that the atmosphere will only keep water [measured vertically] about 32 feet at near sea level pressures. I am taking a swag at it and saying that plants use a combination of capillary action and evaporation to bring water above the nominal 32 feet of water sea level barometric pressure.
FROM PREVIOUS COMMENT: "Again, if you think the term "negative pressure" is not accurate, say so, but don't try to redefine it if you have no idea what you're talking about. If you get a sealed syringe and pull the plunger, what kind of pressure are you applying to the air sealed inside? Depends on the reference perhaps? This is how the water goes UP in the plants."
I understood Nasa to say 'wiper blades' would not be effective due to the nature of the fine dust chemically sticking to the surface of the solar cells. Mechanical sweeping does not solve the real problem of the dust sticking to the solar panel.
Just a guess based on Nasa commentary is the batteries will fail before the solar panels fail to charge them.
There will still be drunk drivers on the roads in NM. Devices are disabled; people drive in from other states. Better yet are high on some other drug or are simply unfit to drive a auto.
Sure you will get a percentage of the drivers, but not enough of them to call the legislation a success.
Sorry NM Legislature, but you are thinking like a 'middle-schooler'.

Think about this - Man went to the moon and the excitment did not last long.
It is much less expensive and much less painful to blow up or burn up a machine in the hopes of exploring a moon or a planet than it is killing a person.

1) It is less complex to insert a craft from earth near the equator than at the poles.
2) There is more solar energy available at the equator.
3) They are more interested in the geology of a lake bed [IE, history of liquid water than they are looking at ice.
4) Not much is known about the surface of Mars. The two landing sites are good candidates for exploration.
We are told there is water [ice] on the moon, then there is not water on the moon.
They talk about sheets of ice subsurface being present in the article, or now maybe it is just crystals. What scientific reason would ice remain on the moon? They do not say. Still I am not surprised they cannot find clear evidence of water on the moon.
They can look and look for whatever they want to find. Point is if water is there, then water isn't there, then nothing is being said. They just as well say, "We are confused."
The only guarantee you will have is the bandwidth to the head-end [cable company] will increase to 3mb/s. If they have not increased their bandwidth to the internet what is there to be really excited about?

The closest product I have seen in recent years is the Dolch. It is bigger than the Acer.
It sounds like a cool product. I hope they do well with it.
I recall a reviewer calling PCs larger than laptops 'trans-lugables.'

An analog watch hows where you are headed and where you were.
Conversley, a digital one tells you where you are in a moment of time.
A very short glance tells you where the minute hand is. The lighting must be just so with a digital display and reading numbers just takes more time.

Ice will go directly to a gaseous state. The moon has no atmosphere, btw.
Meaning if it were there it would have evaporated long ago.

Compute happily.
Perhaps it would not be too hard to look towards the earth given your were pre dawn or post dusk on Mars.
Bottom line, the Earth is *not* illuminated on the side facing Mars! It would be a nearly invisible black disk.
That is a great assumption. I am only aware of one VSS line from the PCM.
If there were two, the cost is higher, and you could disable the one you did not want.
Ah yes, it does as you say.
But, it will not read the DERM / SIR system which is the Black Box from which this thread is about.
A Tech II scanner is supposed to be able to read the SIR system as well.
