Voyager 1 at the Edge

The ancient spacecraft launched in 1977 keeps going onward and upward toward interstellar space with primitive computer chips to guide it. At the edge of the solar system where unusual U.F.O.'s visiting skies in Arizona could be mirthfully planning jaunts to perplex locals the Voyager 1 tiny spacecraft is finding more intense cosmic rays. The charged particles from the sun that evidently fade out at the heliopause don't screen out the interstellar stuff so far away.

By the year 2050 it is believed that the world's carbon dioxide parts per million level will reach the critical 561 level thus doubling what it was in 1890. The world atmospheric temperature ought to be 2 decrees centigrade warmer compared to what it should-and that might cascade a plethora of undesirable changes upon the people of the Earth.

A next generation Voyager interstellar mission using an ion drive and with better instruments to measure the beyond the heliopause environment should be launched containing all kinds of relevant data on human caused global warming economic actions in order to keep a record for any potential survivors of the possible approaching global disaster 'out there'.
