The following information is about Vapor.
Vapor Defined
A substance in the gas state that is below its critical temperature but still suspended in air. It is possible for a vapor to be liquefied by increased pressure. Vapors are usually not visible. [Environmental Pollution; v123; p413-425; 2003] [Atmospheric Environment; v37; p1223-1230; 2003]
Venus- Second planet from the sun; mass 4.872 x 1027g; radius of cloud surface about 6100 Km; radius of solid surface about 6056 Km; surface temperature 737K; temperature of cloud tops 250K; cloud composition more than 75% H2SO4 and about 25% water; atmosphere (by volume) 90-95% CO2 with traces of SO2, water, CO, H2SO4, Ar, Ne, HF, HCl. Atmospheric pressure 92-95 atm. [Hopkins, Jeanne. Glossary of Astronomy and Astrophysics. pg 187; 1980; University of Chicago Press.]

Snowfall on Mars? NASA's Phoenix Lander recorded it
Published July 3, 2009, 6:27 am, Ars Technica
NASA's Mars Phoenix Lander , which spent the summer in Mars' northern polar regions performing a variety of science experiments, caused quite a stir when rumors circulated that it had discovered signs of life on the Red Planet. NASA eventually held a press conference to dispel the rumors, promising that more details would eventually be revealed when scientists got around to publishing papers ...

NASA Phoenix Results Point to Martian Climate Cycles
Published July 2, 2009, 10:17 pm, Mars Today
Favorable chemistry and episodes with thin films of liquid water during ongoing, long-term climate cycles may sometimes make the area where NASA's Phoenix Mars mission landed last year a favorable environment for microbes.
Mars More Like Earth Than Thought? New Details About History Of Water On Red Planet
Published July 2, 2009, 9:23 pm, Science Daily
New details have emerged about the history of water on Mars, gleaned from the 2008 NASA Phoenix Mars Mission. Scientists found patterns in the ground near the lander, multi-sided shapes about three to ten meters in size. The shapes are created when the surface contracts and the ice cracks. Sand fills in the cracks before the ice expands and buckles the surface to make the distinctive patterns.

Tucson, Ariz - Four papers in the journal Science this week offer new details about the history of water on Mars, gleaned from the 2008 NASA Phoenix Mars Mission that was operated from The University of Arizona. Peter H. Smith, a scientist with the UA Lunar and Planetary Laboratory and the mission's principal investigator, is the first author of "H2O at the Phoenix Landing Site" in Science. ...
Perchlorates and Water Make for Potential Habitable Environment on Mars
Published July 2, 2009, 12:47 pm, Universe Today
Scientists say that the Arctic region studied by Phoenix lander may be a favorable environment for microbes. Just-right chemistry and periods where thin films of liquid water form on the surface could make for a habitable setting. "Not only did we find water ice, as expected, but the soil chemistry and minerals we [...]
