Topic: NASA’s Europa Clipper
Pasadena, CA – The surface of Jupiter’s moon Europa features a widely varied landscape, including ridges, bands, small rounded domes and disrupted spaces that geologists call “chaos terrain.” Three newly reprocessed images, taken by NASA’s Galileo spacecraft in the late 1990s, reveal details in diverse surface features on Europa.
Although the data captured by Galileo is more than two decades old, scientists are using modern image processing techniques to create new views of the moon’s surface in preparation for the arrival of the Europa Clipper spacecraft.
Pasadena, CA – Where did life first form on Earth? Some scientists think it could have been around hydrothermal vents that may have existed at the bottom of the ocean 4.5 billion years ago.
In a new paper in the journal Astrobiology, NASA scientists at the Jet Propulsion Laboratory describe how they mimicked possible ancient undersea environments with a complex experimental setup.
They showed that under extreme pressure, fluid from these ancient seafloor cracks mixed with ocean water could have reacted with minerals from the hydrothermal vents to produce organic molecules – the building blocks that compose nearly all life on Earth.
Jim Bridenstine addresses NASA’s ambitious plans for the coming years, including Mars Sample Return.
Washington, D.C. – “President Donald Trump’s Fiscal Year 2021 budget for NASA is worthy of 21st century exploration and discovery. The President’s budget invests more than $25 billion in NASA to fortify our innovative human space exploration program while maintaining strong support for our agency’s full suite of science, aeronautics and technology work.
“The budget proposed represents a 12% increase and makes this one of the strongest budgets in NASA history. The reinforced support from the President comes at a critical time as we lay the foundations for landing the first woman and the next man on the South Pole of the Moon by 2024. This budget keeps us firmly on that path.
Pasadena, CA – NASA’s little robotic explorer will be rolling into Antarctica this month to perform a gymnastic feat – driving upside down under sea ice.
BRUIE, or the Buoyant Rover for Under-Ice Exploration, is being developed for underwater exploration in extraterrestrial, icy waters by engineers at NASA’s Jet Propulsion Laboratory in Pasadena, California. It will spend the next month testing its endurance at Australia’s Casey research station in Antarctica, in preparation for a mission that could one day search for life in ocean worlds beyond Earth.
Pasadena, CA – NASA has announced the mission to explore Jupiter’s moon Europa is a go.
An icy ocean world in our solar system that could tell us more about the potential for life on other worlds is coming into focus with confirmation of the Europa Clipper mission’s next phase. The decision allows the mission to progress to completion of final design, followed by the construction and testing of the entire spacecraft and science payload.

Hampton, VA – NASA says it probably goes without saying, but this isn’t your everyday satellite dish.
In fact, it’s not a satellite dish at all. It’s a high-gain antenna (HGA), and a future version of it will send and receive signals to and from Earth from a looping orbit around Jupiter.
The antenna will take that long journey aboard NASA’s Europa Clipper, a spacecraft that will conduct detailed reconnaissance of Jupiter’s moon Europa to see whether the icy orb could harbor conditions suitable for life. Scientists believe there’s a massive salty ocean beneath Europa’s icy surface. The antenna will beam back high-resolution images and scientific data from Europa Clipper’s cameras and science instruments.
Washington, D.C. – Scientists re-examining data from an old mission bring new insights to the tantalizing question of whether Jupiter’s moon Europa has the ingredients to support life. The data provide independent evidence that the moon’s subsurface liquid water reservoir may be venting plumes of water vapor above its icy shell.
Data collected by NASA’s Galileo spacecraft in 1997 were put through new and advanced computer models to untangle a mystery — a brief, localized bend in the magnetic field — that had gone unexplained until now.

Pasadena, CA – As the Cassini spacecraft nears the end of a long journey rich with scientific and technical accomplishments, it is already having a powerful influence on future exploration. In revealing that Saturn’s moon Enceladus has many of the ingredients needed for life, the mission has inspired a pivot to the exploration of “ocean worlds” that has been sweeping planetary science over the past decade.
“Cassini has transformed our thinking in so many ways, but especially with regard to surprising places in the solar system where life could potentially gain a foothold,” said Thomas Zurbuchen, associate administrator for NASA’s Science Mission Directorate at Headquarters in Washington. “Congratulations to the entire Cassini team!”
Washington,D.C. – NASA’s partnership in a future European Space Agency (ESA) mission to Jupiter and its moons has cleared a key milestone, moving from preliminary instrument design to implementation phase.
Designed to investigate the emergence of habitable worlds around gas giants, the JUpiter ICy Moons Explorer (JUICE) is scheduled to launch in five years, arriving at Jupiter in October 2029. JUICE will spend almost four years studying Jupiter’s giant magnetosphere, turbulent atmosphere, and its icy Galilean moons—Callisto, Ganymede and Europa.
NASA’s Cassini mission and Hubble Space Telescope provides new details about moons Enceladus and Europa

Washington, D.C. – Two veteran NASA missions are providing new details about icy, ocean-bearing moons of Jupiter and Saturn, further heightening the scientific interest of these and other “ocean worlds” in our solar system and beyond. The findings are presented in papers published Thursday by researchers with NASA’s Cassini mission to Saturn and Hubble Space Telescope.
In the papers, Cassini scientists announce that a form of chemical energy that life can feed on appears to exist on Saturn’s moon Enceladus, and Hubble researchers report additional evidence of plumes erupting from Jupiter’s moon Europa.
