Ring formation and evolution offer tantalizing clues to planetary formation processes. First discovered by Galileo in 1610, Saturn’s rings have long fascinated scientists. The robot, dubbed the Exobiology Extant Life Surveyor, features cameras and lidar on its head to help it navigate the unknown environment of Enceladus' ocean floor. Saturns year is nearly 30 Earth years long, and during its long time there, Cassini has observed winter and spring in the north, and summer and fall in the south. Cameras, radio sounders and lasers would remotely scan the moon's surface, The Planetary Society reported.Īnother proposed mission involves sending an autonomous " snake robot" into the watery depths below Enceladus' surface. A SpaceX Falcon 9 rocket launched all of these satellites on the Transporter-8 mission. Orbilander would carry instruments to weigh and analyze molecules, as well as a DNA sequencer and a microscope. The image above shows 72 spacecraft that headed to orbit on June 12. Then, the spacecraft would convert into a lander, descending on the surface of the icy moon. The proposed Enceladus Orbilander would orbit the moon for about six months, flying through its watery plumes and collecting samples. NASA scientists are discussing future return missions to seek out signs of life on Enceladus. New NASA research confirms that Saturns rings are being pulled into Saturn by gravity as a dusty rain of ice particles under the influence of Saturns magnetic. Scientists think the spurts of water sensed by JWST and Cassini come from hydrothermal vents in the ocean floor - a hypothesis supported by the presence of silica, a common ingredient in planetary crusts, in the vapor plumes. Enceladus is totally encrusted in a thick layer of water ice, but measurements of the moon's rotation suggest that a vast ocean is hidden beneath that frozen crust. Water is another piece of evidence in the case for possible life on Enceladus. 2 stars covered in unusual elements have a puzzling origin story For the first time, scientists watched a dying star swallow a planet whole Astronomers find remnants of the oldest stars in the universe
