Currently,where are the Voyagers 1 and 2 space probes?
Asked by: Sara Irina Md. Rijaluddin


Both are well and truly outside the solar system. Voyager 1 has left the termination shock to enter the heliosphere, a region still influenced by the solar wind. It is about 12 light hours, or about 13 billion kilometres from Earth. Voyager 2 hasn't yet reached the termination shock, and is a 'mere' 11 billion kilometres from Earth. Here's a photo from NASA:

According to NASA, here is the data for the two space probes on April 9 2004 :

Distance from the Sun (Km)
Voyager 1 - 13,702,000,000
Voyager 2 - 10,925,000,000

Voyager 2 - 6,789,000,000

Voyager 1 - 13,629,000,000
Voyager 2 - 10,924,000,000

Distance from the Earth (Mi)
Voyager 1 - 8,469,000,000
Voyager 2 - 6,787,00,000

Total Distance Traveled Since Launch (Km)
Voyager 1 - 15,566,000,000

Voyager 2 - 50,151

Round Trip Light Time (hh:mm:ss)
Voyager 1 - 25:14:34
Voyager 2 - 20:14:16

But where exactly are they? Both Voyagers are headed towards the outer boundary of the solar system in search of the heliopause, the region where the Sun's influence wanes and the beginning of interstellar space can be sensed. The heliopause has never been reached by any spacecraft; the Voyagers may be the first to pass through this region, which is thought to exist somewhere from 8 to 14 billion miles from the Sun. Sometime in the next 5 years, the two spacecraft should cross an area known as the termination shock. This is where the million-mile-per-hour solar winds slows to about 250,000 miles per hour�the first indication that the wind is nearing the heliopause. The Voyagers should cross the heliopause 10 to 20 years after reaching the termination shock. The Voyagers have enough electrical power and thruster fuel to operate at least until 2020.

Science Quote

'The strength and weakness of physicists is that we believe in what we can measure. And if we can't measure it, then we say it probably doesn't exist. And that closes us off to an enormous amount of phenomena that we may not be able to measure because they only happened once. For example, the Big Bang. ... That's one reason why they scoffed at higher dimensions for so many years. Now we realize that there's no alternative... '
