In Grinspoon's view, the findings of Magellan and other spacecraft have shown Venus to be our planet's "fraternal twin". While differing severely in many characteristics, Venus closely matches earth in others-size, mass, and distance from the sun, a geologically active and volcanic surface and an evolving atmosphere with complex chemical cycles.
Architects try to pin down ideas that are floating in the cultural atmosphere, chief among them, perhaps, the evolving relationship of self to community in a modern democracy.
In microgravity, one of the major challenge encountered in biological life support systems (BLSS) is the gas liquid transfer with, for instance, the necessity to provide CO2 (carbon source, pH control) and to recover the evolved O2 in photobioreactors used as atmosphere bioregenerative systems.
The main forces and torques originate from the gravity field (always present), from the propulsion system (when switched on) and possibly from the aerodynamics shape when the vehicle evolves in an atmosphere.
In other ways it has a highly evolved party atmosphere.
The offbeat atmosphere evolved with the times.
The free oxygen that makes up the bulk of the present atmosphere evolved over geologic time by two possible processes.
"A mission that was able to probe the internal structure of the planet, to sniff out the atmospheric composition and understand how the atmosphere evolves would allow us to put together the puzzle about how planets form".
At the beginning of the simulations, the researchers gave Pluto a planet-wide veneer of nitrogen, carbon monoxide, and methane ices a few millimeters thick; then, the planet's surface and atmosphere evolved as the icy orb passed through orbit after orbit.
The circumstances, an evolving epidemic occurring in a worldwide atmosphere of tremendous uncertainty, elicited a unique response, which went beyond the traditional industrial hygiene investigative model.
