Is the atmosphere of Mars still reducing today by the influence of the solar wind? Or is it now a balanced ?

neilsox":1bzwan4l said:China syndrome is likely a serious exaggeration, The molten plutonium likely sinks into the soil about 30 feet instead of 3000 miles to reach the core of Mars. Our present technology suggest that we can not get the high level nuclear waste to the core of Mars and all of it would likely warm the core only about one degree for a few centuries. Even if we could heat the core of Mars to 1000 degrees c = 1832 f a much weaker magnetic field than Earth is likely. Induction heating is a possible way to heat the core of a planet, but the electric bill would exceed all the riches of Earth.
Mars settlers can likely survive the extra radiation long enough to have children at least half of the time, but the life expectancy may be half that in advanced Earth countries, unless they stay in radiation shelters most of the time.
There are numerous hurdles to complete the terraforming of Mars and the final results may be unsatisfactory in hundreds of ways. We can be sure of the engineering of hardly anything until we try, and the present cost says don't try until we are much richer and much smarter. Neil
