The gallery's director, Betti-Sue Hertz, has brought three installation pieces that seem to want to say a lot, but that none of which conjure the atmospheric density to which this medium is suited.
32.
Another negative effect of lower atmospheric density can be manifested in the form of thermal oscillations, which can lead to high variability in the global climate and increase the chance for catastrophic events.
33.
Mission officials also hoped instruments would reveal new details of its atmospheric density, which would be useful when Cassini launches the European Space Agency's Huygens probe for a descent to Titan's surface in January.
34.
"' MIMOSA "'( Mi cro m easurements o f S atellite A cceleration ) is a Czech scientific microaccelerometer to monitor the atmospheric density profile by sensing the atmospheric drag on the approximated sphere.
35.
Frequently-occurring dust storms increase lower atmospheric temperature and lessen atmospheric density, which, coupled with the extremely variable elevations on Mars'surface, forces a conservative selection of a landing site in order to allow for sufficient craft deceleration.
36.
Mars'combination of thin atmospheric density and relatively large gravity makes it impossible for a conventional heat shield to brake landing capsules of more than a few tons'mass to subsonic velocity before they would impact the surface.
37.
NASA said Tuesday it has temporarily suspended the novel " aerobraking " maneuvers of its orbiting Mars Global Surveyor because of stress on a solar array caused by an unanticipated increase in the planet's atmospheric density.
38.
If the size of the fireball is comparable to the atmospheric density scale height, the whole cloud rise will be ballistic, overshooting a large volume of overdense air to greater altitudes than the final stabilization altitude.
39.
A final observation is that the plasma densities needed in the laboratory are sizeable, up to 10 16 cm " 3 for the ionosphere, compared to the atmospheric density of about 10 19 particles per cm 3.
40.
The reappearance of liquid water on the Martian surface would add to the warming effects and atmospheric density, but the lower gravity of Mars requires 2.6 times Earth's column airmass to obtain the optimum 100 kPa pressure at the surface.
