EUROPA CLIPPER (NASA SPACECRAFT)

NASA Night Sky Network members joined us on October 16, 2018 to hear Robert Pappalardo bring us up to date on the Europa Clipper mission. Jupiter's moon Europa may be a habitable world.  Galileo spacecraft data suggest that a global ocean exists beneath its frozen ice surface. A scarcity of large craters argues for a young surface and recent geological activity, and magnetometry implies that a salty ocean persists today. Europa's ocean and surface are inherently linked: tidal deformation of the floating ice shell could generate stresses that fracture and deform the surface to create ridges and bands, while dark spots, domes, and chaos are probably related to tidally driven ice convection and partial melting. Europa's activity may permit the "ingredients" necessary for life – water, chemistry, and energy – to be present within the satellite's ocean. NASA is planning a robotic mission to explore Europa and investigate its habitability, employing a highly capable suite of remote sensing and in situ instruments on a spacecraft that will make multiple close flybys.   The Europa Clipper mission will interrogate the moon’s ice shell, ocean, composition, and geology including any current activity.  This talk will summarize both our state of knowledge about Europa and the science potential of the Europa Clipper mission to explore Europa and investigate its habitability.  About Robert Pappalardo Dr. Robert Pappalardo is the Project Scientist for NASA’s Europa Clipper Mission at the Jet Propulsion Laboratory, California Institute of Technology.  He has also served as the Project Scientist for the Cassini Equinox (first extended) Mission at Saturn, for which he received NASA’s Exceptional Service Medal.  He has served as a member of the National Research Council’s Space Studies Board and as Co-Chair of its Committee on the Origins and Evolution of Life. He received his B.A. in Geological Sciences from Cornell University in 1986, and he obtained his Ph.D. in Geology from Arizona State University in 1994. His research focuses on processes that have shaped the icy satellites of the outer solar system, especially Europa and the role of its probable subsurface ocean.

Robert Pappalardo - Project Scientist, Europa Clipper, JPL From the 20th Annual International Mars Society Convention, held at University of California Irvine from Sept 7-10, 2017. The four-day International Mars Society Convention brings together leading scientists, engineers, aerospace industry representatives, government policymakers and journalists to talk about the latest scientific discoveries, technological advances and political-economic developments that could help pave the way for a human mission to the planet Mars.

Two long-running NASA missions are providing new details about ocean bearing moons of Jupiter and Saturn – further heightening scientific interest in these and other “ocean worlds” in our solar system and beyond. The details – discussed during an April 13 NASA science briefing – include the announcement by the Cassini mission that a key ingredient for life has been found in the ocean on Saturn's moon Enceladus. Meanwhile, researchers using the Hubble Space Telescope observed a probable plume erupting from the surface of Jupiter's moon Europa, at the same location where Hubble saw evidence of a plume in 2014. Researchers say this could be circumstantial evidence of water erupting from the moon’s interior. Hubble's monitoring of plume activity on Europa and Cassini's long-term investigation of Enceladus are laying the groundwork for NASA's Europa Clipper mission, which is being planned for launch in the 2020s.

During a NASA science briefing on April 13, representatives from the agency discussed new results about ocean worlds in our solar system based on data gathered by NASA’s Cassini spacecraft and the Hubble Space Telescope. The two veteran missions are providing tantalizing new details about icy, ocean-bearing moons of Jupiter and Saturn, further enhancing the scientific interest of these and other "ocean worlds" in our solar system and beyond. New research from Cassini indicates that hydrogen gas, which could potentially provide a chemical energy source for life, is pouring into the ocean of Saturn's icy moon Enceladus from hydrothermal vents in the seafloor. The Cassini spacecraft detected the hydrogen in the plume of gas and icy material spraying from Enceladus during its deepest dive through the plume on Oct. 28, 2015.This means that ocean microbes -- if any exist there -- could use the hydrogen to produce energy NASA’s Hubble Space Telescope saw a probable plume of material erupting from the moon’s surface on 2016, at the same location where Hubble saw evidence of a plume in 2014. These images bolster evidence that the Europa plumes could be a real phenomenon, flaring up intermittently in the same region on the moon's surface. Both Cassini and Hubble investigations are laying the groundwork for NASA's Europa Clipper mission, which is being planned for launch in the 2020s.

The Hubble Space Telescope has captured even more evidence of water vapor plumes on Jupiter's icy moon Europa. The probable plumes appear to be repeating in the same location and correspond with a relatively warm region on Europa's surface observed by the Galileo spacecraft.

The Europa Clipper spacecraft is the formal name of NASA's scheduled mission to orbit and observe Jupiter's moon Europa. The mission will tour the moon from orbit. Scheduled to launch in 2020, the spacecraft is named after a type of sailing ship developed in the 19th century. Clippers were fast for their times, with a narrow hull for their long frames. However, the space fairing vessel will not be taking tea out into the solar system, like the trading ships of old. Instead, the Europa Clipper will conduct at least 40 flybys of Jupiter's moon as it gathers data and images. https://www.cnet.com/news/nasa-jupiter-europa-moon-clipper/#ftag=CAD590a51e http://www.wochit.com This video was produced by YT Wochit Tech using http://wochit.com

NASA's Hubble Space Telescope took direct ultraviolet images of the icy moon Europa transiting across the disk of Jupiter. Out of ten observations, Hubble saw what may be water vapor plumes on three of the images. This adds another piece of supporting evidence to the existence of water vapor plumes on Europa - Hubble also detected spectroscopic signatures of water vapor in 2012. The existence of water vapor plumes could provide a future Europa flyby mission the opportunity to study the conditions and habitability of Europa's subsurface ocean.

Exploring Space Lectures Presenter: Robert Pappalardo, Jet Propulsion Laboratory Jupiter's moon Europa may have an internal ocean of liquid water, plus the chemistry and energy life needs to exist. Robert Pappalardo, Europa Mission project scientist at the Jet Propulsion Laboratory, will discuss NASA’s plans to send a robotic mission to evaluate Europa’s potential for life and address one of humanity’s most fundamental questions: Are we alone in the universe? The Exploring Space lectures are made possible by the generous support of Aerojet Rocketdyne and United Launch Alliance.

Jupiter's watery moon Europa is the next big target in the search for life beyond Earth. And the easiest way to search is to get up close and personal — right on the surface. In February 2015, NASA announced plans for Europa Clipper, a flyby mission. Later in the year, NASA engineers started considering adding a lander. While Europa Clipper would make wide orbits around Jupiter and close passes to Europa, the lander will get close enough to prod the surface with its sensors. It could touch down with the help of a skycrane, like the one that delivered the Curiosity rover to Mars. The lander would carry rotating saws and scoops to dig into the ice of the crust, as well as instruments to look for signs of life. And it would have about 10 days to do its work because not even robots can stand up to the radiation pouring off Jupiter for long. It's a short window, and one that's still six years away, but Congress seems to think the science is worth it. Since NASA announced the mission, lawmakers have pumped cash into the Europa program, set launch deadlines for both orbiter and lander missions, and directed NASA to use the Space Launch System to get its probes where they need to go.

NASA Hits Milestone For New Exploration Mission To Europa Follow Sebastian Martinez: http://www.twitter.com/SebastianSings See more at http://www.newsy.com Transcript: NASA’s planned mission to Europa has passed its first internal review and now enters the stage known as formulation. This would be NASA’s first visit to Jupiter or its moons since New Horizons flew by on its way to Pluto, and the first dedicated science probe since the Galileo mission wrapped up its tour of Jupiter and its moons in 2003. Europa is one of the leading candidates for worlds that might support life beyond Earth. The mission, which doesn’t have an official name yet, would send a dedicated probe to investigate Europa’s physical characteristics and evaluate its potential for supporting life. (Video via NASA) The Galileo mission showed Europa exerted influence on Jupiter’s magnetic field, consistent with conductive fluid beneath the moon’s icy surface. The leading theory now is Europa is covered by a global ocean of saltwater. This new mission’s science payload is designed to explore that possibility. “Cameras and spectrometers to collect high-resolution imagery, an ice-penetrating radar to measure surface thickness and look for subsurface lakes, and a magnetometer to measure the strength and direction of the moon’s magnetic field.” (Video via NASA) One problem is the radiation. Jupiter emits high-energy electrons that can damage sensitive equipment aboard space probes. “Any mission that goes in the vicinity of Europa is cooked pretty quickly. Instead we’re looking at a mission that would orbit Jupiter, make close flybys of Europa, and then zip out of the high-radiation region,” said project scientist Robert Pappalardo. (Video via NASA) The probe would complete an orbit around Jupiter every two weeks or so, for an expected total of 45 flybys. It will be a while, though. This early in the process NASA hasn’t even started assembling the spacecraft. A launch isn't expected until sometime in the 2020s.
