View od the fully assembled James Webb Space Telescope. The sunshield and unitized pallet structures (UPSs) that fold up around the telescope for launch, are partially deployed to enable telescope installation. Photo Credit: NASA/Chris Gunn NASA’s James Webb Space Telescope (JWST) just took another big step towards completion, as the two halves it was […] 
Artist’s concept of Europa Clipper during a flyby of Europa. Image Credit: NASA/JPL-Caltech NASA’s next mission back to Jupiter’s moon Europa just took another big step towards reality. The next phase of Europa Clipper has been confirmed, giving the go-ahead for the mission to proceed to final design, construction and testing. […] 
Illustration of the Galileo probe at Europa in 1997, and how the plume disrupted the moon’s magnetic field. Image Credit: NASA/JPL-Caltech/Univ. of Michigan For decades, Jupiter’s moon Europa has fascinated scientists and the public alike after it was learned that a global water ocean lies beneath the icy crust. Could there be life […] 
Artist’s conception of the Europa lander. Image Credit: NASA/JPL-Caltech The push for a return mission to Jupiter’s moon Europa has been gaining steam in the last few years, with NASA now planning for Europa Clipper, which would make repeated close flybys to study the moon’s interior ocean and the exciting potential for life. […] 
An example of possible spectroscopy results from one of Europa’s water vapor plumes. Image Credit: NASA-GSFC/SVS/Hubble Space Telescope/Stefanie Milam/Geronimo Villanueva NASA’s upcoming James Webb Space Telescope (JWST) will be used to study two of the most fascinating moons in our Solar System – Europa and Enceladus, also known as “ocean worlds” since both […] 
Artist’s conception of the proposed Europa lander, with sampling arm extended. Image Credit: NASA/JPL-Caltech For decades now, Europa has beckoned – this moon of Jupiter which is frozen on the outside but hides a global ocean on the inside – has so far only been visited by spacecraft during brief flybys. Scientists and […] 
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, […] 
Composite image showing the possible water vapor plumes near the south pole of Europa, at about the 7 o’clock position. The image of Europa, from the Galileo and Voyager missions, is superimposed on the Hubble data. Image Credit: NASA/ESA/W. Sparks (STScI)/USGS Astrogeology Science Center Intriguing new findings about Jupiter’s moon Europa were announced […] 
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 […] 
The discovery of huge faults on Pluto provides evidence for a possible liquid water ocean beneath the ice crust. Photo Credit: NASA/JHUAPL/SwRI So-called “waterworlds” have been found to be surprisingly common in the Solar System—small icy moons which have ice crusts but oceans of liquid water below the surface. These include Jupiter’s moons […] |
