The 70-meter-wide (230-feet-wide) radio antenna at the Deep Space Network’s Canberra site in Australia. It is the only antenna that that communicate with Voyager 2 from the southern hemisphere, and will be undergoing crucial upgrades for 11 months beginning in March.

Artist’s concept of Triton and its thin atmosphere, with Neptune and the distant Sun in the background. Image Credit: European Southern Observatory (ESO) Thirty years ago, this month, humans and technology steeled themselves for the last, first-time, close-up glimpse of a new planet in the 20th century. NASA’s Voyager 2 spacecraft, launched in August […] 
Neptune and its large moon, Triton, as seen by Voyager 2 in August 1989, three days after closest approach. Photo Credit: NASA Thirty years ago, this month, all eyes were on the outermost reaches of the Solar System, as humanity braced itself for its last, first-time, close-up glimpse of a new planet in the […] 
Artist’s concept of one of NASA’s Voyager spacecraft, including the location of the cosmic ray subsystem (CRS) instrument. Image Credit: NASA/JPL-Caltech With all of the current and recent planetary missions throughout the Solar System, it may be easy to forget sometimes that there are still some older spacecraft that have been traveling for decades […]

Photo Credit: NASA/Johns Hopkins University Applied Physics Laboratory/Southwest Research Institute NASA’s New Horizons spacecraft is way, way past Pluto now and still nearly a year away from its next encounter with an object in the Kuiper Belt, but that […] 
Artist’s conception of Voyager 1 reaching interstellar space. Image Credit: NASA/JPL-Caltech NASA’s Voyager 1 spacecraft is one of the greatest achievements in space exploration, becoming the first probe to reach interstellar space, after epic flybys of Jupiter and Saturn in 1979 and 1980. Since then, Voyager 1 has remained healthy although its thrusters […] 
The Voyager adventure began 40 years ago, today, on 20 August 1977. Image Credit: NASA/JPL-Caltech Forty years ago, today, on 20 August 1977, a space explorer rose from Earth on a multi-decade adventure, which would unveil all four of the Solar System’s giant gaseous planets in unprecedented detail. Despite being originally detailed to […] 
From NASA: “NASA’s Juno spacecraft captured this view as it closed in on Jupiter’s north pole, about two hours before closest approach on Aug. 27, 2016.” Image Credit: NASA/JPL-Caltech/SwRI/MSSS Jupiter, with its complex layers of clouds and storms, is revealing itself to be a multifaceted jewel of a planet. Over forty years […] 
Artist’s conception of Juno approaching Jupiter. Image Credit: NASA Jupiter has often been referred to as the King of Planets, and for good reason, as it is a massive gas giant, much larger than Earth and the largest planet in our Solar System. It is more than 2.5 times as massive as all […] 
Visible only as a crescent, Uranus recedes from Voyager 2 in the days after Closest Approach. Photo Credit: NASA Thirty years ago, today and tomorrow, NASA’s Voyager 2 spacecraft gave humanity its first close-up glimpse of Uranus. Known for more than two centuries, and frequently the “butt” of many off-color jokes, this giant […] |
