Hubble telescope is now working to create maps of interstellar routes that will be helping the space voyagers to explore the wide space. The road map is being created for the two Voyager spacecraft that are now on their interstellar missions.
In the case when both the spacecraft run out of electrical power and are unable to send back new data, Hubble’s observations can be used to determine the environment through which they will glide. The preliminary analysis of the Hubble observations has shown the multiple clouds of hydrogen and other elements in the complex interstellar ecology.
The Voyager 1 and 2 spacecraft were launched by NASA in 1977 and since then they have explored a large part of our solar system and have now moved on to their interstellar journey outside the Sun’s domain. Both the spacecraft explored the outer planets Jupiter and Saturn, while the Voyager 2 visited Uranus and Neptune.
Voyager 1 is now 13 billion miles away from the Earth and this is the farthest a human-made object has ever gone. It is exploring the outer space, the region between the stars which is filled with gas, dust and materials from dying stars. The Voyager 2 is about 10.5 billion miles away from the Earth.
In about 40,000 years, the Voyager 1 will pass within 1.6 light-years of the star Gliese 445, in the constellation Camelopardalis. While the Voyager 2 pass 1.7 light-years from the star Ross 248 in the same period.
“This is a great opportunity to compare data from in situ measurements of the space environment by the Voyager spacecraft and telescopic measurements by Hubble,” said Seth Redfield of Wesleyan University in the US. “The Voyagers are sampling tiny regions as they plow through space at roughly 38,000 miles per hour. But we have no idea if these small areas are typical or rare,” he added.
