NASA's Voyager 1 spacecraft is currently riding the wave of an interstellar tsunami, as it continues its historic march out of our solar system. The tsunami emanated from our Sun, and was the third such phenomenon of its type to be detected by the robotic pioneer.  Read More

NASA has released global maps of six of the Saturnian moons. The system has been under the intense examination of the Cassini-Huygens mission for the past decade, and the completion of the global maps represents the end of one of the legendary spacecraft's key mission objectives. Almost all of the maps are whole, though there are currently parts of Iapetus unfinished, as well as a region of the north pole of Enceladus set to be filled in some time next year.  Read More

NASA scientists have produced the first global geological map of Jupiter's largest moon Ganymede by combining images from over twenty years of observation by the Voyager spacecraft and the Galileo orbiter.  Read More

After a journey of 36 years, NASA has announced that the Voyager 1 space probe officially left the Solar System on August 25, 2012. Based on new analysis of data sent by by the unmanned spacecraft, the space agency has declared that it is now in the first man-made object to travel into interstellar space, 12 billion miles (19 billion km) from the Sun.  Read More

Sometimes it seems as though the Voyager 1 space probe is like a dog that can’t decide if it wants to be inside or out. A team of scientists led by the University of Maryland claim that the Voyager 1 space probe, which is now 11 billion miles (18 billion km) from Earth left the Solar System’s boundary last year and is not, as NASA claims, passing through a transition zone. The controversial theory is based on models of the solar magnetic field on the edge of the system and how it interacts with interstellar space.  Read More

The history of spaceflight is filled with great images, such as Neil Armstrong setting foot on the Moon or Viking 1’s first images from Mars, but some of the most dramatic events haven’t any images to accompany them. As NASA's two Voyager spacecraft leave the Solar System, there won’t be any historic pictures sent back. Instead, that invisible boundary between our system and interstellar space will be marked by readings taken by the instruments of the spacecraft. NASA has placed a readout on the Voyager mission home page that shows two of three key factors that will let the public know when this momentous milestone has been reached.  Read More

Has Voyager 1 left the Solar System? Is it officially the first spacecraft to reach interstellar space? It depends on whom you ask. NASA says no, but W.R. Webber of the New Mexico State University Department of Astronomy and F.B. McDonald of the University of Maryland Institute of Physical Science and Technology say yes. They contend that the unmanned, nuclear-powered probe left the Solar System on August 25, 2012 at a distance of 121.7 AU (18.2 billion km) from the Sun when its instruments on board detected a major shift in cosmic ray intensity.  Read More

Voyager 1 has reached yet another new frontier on its historic journey towards the edge of our solar system. NASA scientists believe this “magnetic highway” represents the final region the spacecraft must cross before becoming the first man-made object to reach interstellar space, an event they are guessing could be as close as a couple of months away.  Read More

Based on the latest data received from Voyager 1, scientists say the venerable spacecraft is now on the very edge of our solar system. The data, which traveled some 17.8 billion kilometers (11 billion miles) on its 16-hour-38 minute journey to NASA’s Deep Space Network on Earth, reveals a marked increase in the intensity of charged particles from beyond our solar system, indicating that Voyager 1 is soon to become the first man-made object to leave our little slice of the universe.  Read More

The last time we checked on the Voyager 1 & 2 they were hurtling towards the edge of the solar system at over 37,000 mph (60,000 km/h). The car-sized spacecraft are now and incredible 11 billion miles (17 billion km) and 8 billion miles (14 billion km) from Earth respectively – they are the longest continuously operated spacecraft in deep space and having traveled further than any man-made object, they will soon become the first to enter the realm of interstellar space. NASA recently held a briefing on the achievements of the program which gives us the opportunity to ponder where the Voyagers are, where they are going and the amazing scientific discoveries realized so far in their 33 year journey.  Read More
