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 have […] 
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 visit […] 
Artist’s illustrationn of Voyager 1 looking back on the Solar System. Image Credit: NASA/ESA/G. Bacon (STScI) There have been many incredible planetary missions over the past several decades, from as close as our Moon to the outer reaches of the Solar System. Right now, there are robotic explorers at Mars, Jupiter, Saturn, Ceres, and […] 
Artist’s conception of the Europa Clipper spacecraft near Europa. Image Credit: NASA/JPL-Caltech For a long time now, there has been growing interest in sending a mission back to Jupiter to better study one moon in particular: Europa. Previous missions such as Voyager and Galileo showed us this world up close for the first time, […] 
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 the […] 
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 Sun. […] 
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 gaseous […] 
New high-resolution image of Pluto from New Horizons, showing jumbled blocks in the water-ice crust, which border the smooth nitrogen-ice plains. Image Credit: NASA/JHUAPL/SwRI The New Horizons mission has already sent back phenomenal images and data from Pluto, but it keeps getting better. New images released today are the first in a series of […] 
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 been […] |
