Voyager-1&2

U.S space agency launched Pioneer 10 & 11 probes in 1972 & 1973 respectively, on a very long haul mission of leaving the solar system on a one way journey.  

Then in 1977 NASA launched its better equipped Voyager-1 & 2 probes, both of which flew by Jupiter & Saturn, Voyager 2 also explored Uranes and Neptune.  It has sent photographs of all these planets along with their moons. 

Voyager-1

Officially NASA’s Voyager-1 Spacecraft is the first man-made object to have left the solar system for the dark and mysterious realm of Interstellar space.  It has covered 19 billion kilometers since its launch 36 years ago at a speed of 17 kms per second.  

= 1020 kms/ minute.

= 61,200 kms / hour.

What will take a highway motorist 20,000 years to 

cross this distance.
