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 […] 
Uranus’ moon Miranda shows signs of past geological activity, with deep canyons and other chaotic terrain. Photo Credit: NASA/JPL-Caltech Seventy years ago, the existence of a new world was added to the growing vault of human knowledge. More than 1.8 billion miles (2.9 billion km) from Earth, circling the gaseous planet Uranus, its […] 
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 […] 
Uranus and Neptune: the Solar System’s unique ice giant planets, of which we only got brief glimpses during the Voyager 2 flybys in the 1980s, beckon for further, more detailed exploration. Image Credit: NASA Last year’s historic close flyby of Pluto by NASA’s New Horizons spacecraft put the outer Solar System firmly back […] 
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 […] 
Uranus and its six largest moons, from left Puck, Miranda, Ariel, Umbriel, Titania, and Oberon. Image Credit: NASA At 12:59 p.m. EST (5:59 p.m. GMT) today, exactly three decades passed since NASA’s Voyager 2 spacecraft became the first machine fashioned by human hands to visit Uranus, the seventh planet in line from the […] 
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 […] 
Uranus (left) and Neptune (right). These two ice giants and their many moons are awaiting further exploration. Image Credit: NASA The outer Solar System has been a busy place lately, with the ongoing Cassini mission at Saturn and New Horizons’ recent spectacular flyby of Pluto. Literally in-between those two worlds, however, it has […] |
