bq. It’s been traveling for 28 years and is now 8.7 billion miles from Earth. It just reported that it has entered the region of the heliosheath, where the solar wind begins to dissipate. It may be in this region another 10 years. Its Pt-238 radioisotope thermoelectric generator (RTG) should keep operating until about 2020. When Voyager 1 crosses that final boundary, becoming the first human artifact to enter interstellar space, Earth won’t know. Communications with Voyager will be cut off to save $4.5M of NASA’s $16.5B budget (.025%), for Bush’s Moon/Mars “vision.”
