Where are the Voyager space probes now?
« on: 07/01/2010 04:09:00 »
I was asked a question relating to the Voyager space probes, their missions and their present activity:

This page provides a very nice summary:

This also reminded me of another interesting story we covered in 2002, which was NASA's contacting of the Pioneer 10 probe on its 30th birthday:

Incredible!

I find it fascinating the Voyagers are now traveling at low interstate speeds away from earth [61+ kph]. Are these speeds adequate for escape velocity from the Solar System? Have I missed a decimal or two?

I LOVE this stuff. For instance, perhaps you can report what is the oldest operational satellite? The most distant operational satellite etc. I admit to a certain level of sloth on my part....

Thanks!

The Voyagers must be doing more than 61 kph, surely? They were doing nearly 40,000 mph in the solar system...

If you read the post carefully, you might see a capital K after the numbers -  it isn't 61 kph, it's 61K+ kph = 61,000+ kph

Strictly speaking, 61K is 61 degrees Kelvin, which probably was not the intended meaning. Also, it's not clear what kph is at all.
