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 […] 
The plumes of Enceladus: SELFI would study their composition in more detail than ever before. Photo Credit: NASA/JPL/Space Science Institute Is there life on Enceladus? Are there any Enceladan bacteria or other little critters swimming in that alien ocean on this tiny moon of Saturn? We don’t know yet, but there is compelling […] 
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 […] 
A haunting raw image view of Saturn and its rings taken on June 7, 2017 by Cassini. Photo Credit: NASA/JPL-Caltech/Space Science Institute As Cassini’s “Grand Finale” journey continues, the spacecraft has completed its eighth dive past the innermost rings of Saturn (known as a ring crossing), and there are now just under 100 […] 
Illustration of Cassini crossing the ring plane between Saturn and its innermost rings .Cassini has now completed its second dive into the rings of Saturn, with 20 left to go during the Grand Finale. Image Credit: NASA/JPL-Caltech Cassini’s “dance” with Saturn’s rings continues – the probe has now completed its second dive into […] 
Three of the new raw images taken during Cassini’s first dive between Saturn and its innermost rings. Image Credit: NASA/JPL-Caltech/Space Science Institute After waiting with bated breath last night, everyone following Cassini’s first-ever dive through the gap between Saturn and its rings let out a collective sigh of relief – the spacecraft made […] 
Artist’s conception of Cassini’s final flyby of Titan on April 21. Image Credit: NASA/JPL-Caltech This week marks another important milestone in the Cassini mission at Saturn – as of today, the spacecraft is conducting the last Ring-Grazing Orbit of its mission as it prepares for the Grand Finale, which will culminate in the […] |
