Heliosheath


Voyager 1 a 1,592 lb probe launched by NASA on September 5, 1977 to study the outer Solar System and the interstellar medium (photo from NASA). Operating for 35 years, 1 month and 19 days as of yesterday, the spacecraft receives routine commands and transmits data back to the Deep Space Network. At a distance of about 122 AU (1.83×10 to the 10th power km) it is the furthest manmade object from Earth.

Voyager 1 now at the outer edge of the heliosphere where the sun's solar winds slow (called "termination shock").  In June, NASA noted that Voyager 1 may soon enter interstellar space becoming the first manmade object to leave the Solar System.  The primary mission BTW ended November 20, 1980, after the probe zipped by Saturn.

Voyager 1 a toaster by today's standards - recall the cars made by America back then ? Imagine what our kids will see. 

We watch Steve McQueen in "Bullet".
Madeleine: "What are those?"
Sonnet: "He's buying TV dinners."
Madeleine: "Do you have to eat them in front of the TV?"


A car spins off the road, top speed, hits a gas tank then explodes. The passengers shown burning in the molten metal.
Madeleine: "Are they dead?"
