GREENBELT, Md. — Forty years ago, a Voyager spacecraft snapped the first closeup images of Europa, one of Jupiter’s 79 moons. These revealed brownish cracks slicing the moon’s icy surface, which give Europa the look of a veiny eyeball. Missions to the outer solar system in the decades since have amassed enough additional information about Europa to make it a high-priority target of investigation in NASA’s search for life.
The White House wants Congress to provide more money for the Artemis moon landing program, and to save about $1.5 billion by dropping the requirement that NASA launch the Europa Clipper mission to Jupiter’s icy moon on the Space Launch System (SLS).
LAMPOLDSHAUSEN, Germany (ESA PR) — The assembly of the flight model of ESA’s JUICE spacecraft began in September, with the delivery of the spacecraft’s primary structure, followed by integration of the propulsion system that will enable the mission to reach and study Jupiter and its moons.
On 2 September, the main skeleton of JUICE was delivered to the Arianegroup facility in Lampoldshausen, Germany.
WASHINGTON (NASA PR) — 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 EuropaClipper 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.
“We are all excited about the decision that moves the Europa Clipper
mission one key step closer to unlocking the mysteries of this ocean
world,” said Thomas Zurbuchen, associate administrator for the Science
Mission Directorate at NASA Headquarters in Washington. “We are building
upon the scientific insights received from the flagship Galileo and
Cassini spacecraft and working to advance our understanding of our
cosmic origin, and even life elsewhere.”
The mission will conduct an in-depth exploration of Jupiter’s moon,
Europa, and investigate whether the icy moon could harbor conditions
suitable for life, honing our insights into astrobiology. To
develop this mission in the most cost-effective fashion, NASA is
targeting to have the Europa Clipper spacecraft complete and ready for
launch as early as 2023. The agency baseline commitment, however,
supports a launch readiness date by 2025.
NASA’s Jet Propulsion Laboratory in Pasadena, California leads the
development of the Europa Clipper mission in partnership with the Johns
Hopkins University Applied Physics Laboratory for the Science Mission
Directorate. Europa Clipper is managed by the Planetary Missions Program
Office at NASA’s Marshall Space Flight Center in Huntsville, Alabama.

Nuclear electric propulsion (NEP) systems have the potential to provide a very effective transit mechanism to celestial bodies outside of the realm of solar power, yet the heavy power source and massive radiators required to justify a reactor core often push NEP spacecraft towards very large masses and major missions. If the total mass of an NEP system could be reduced to levels that were able to be launched on smaller vehicles, these devices could deliver scientific payloads to anywhere in the solar system.
PASADENA, Calif. (NASA/JPL-Caltech PR) — NASA has decided to replace the current magnetometer on the upcoming Europa Clipper mission with a less complex instrument. The Europa Clipper mission, launching in the 2020s, will be the first dedicated and detailed study of a probable ocean world beyond Earth. Jupiter’s moon Europa, slightly smaller than Earth’s Moon, may host a liquid water ocean under its frozen shell, making it a tantalizing place to search for signs of life.
NASA has received a $21.5 billion budget for fiscal year 2019, which is $736.86 million above FY 2018 and $1.6 billion above the total requested by the Trump Administration.
The funding, which came more than four months into the fiscal year, was included in an appropriations bill signed by President Donald Trump on Friday. NASA’s budget has been on an upward trajectory over the last few years. In FY 2018, the space agency received an $1.64 billion increase over the previous year.
CARDIFF, UK (Cardiff University PR) — A location often earmarked as a potential habitat for extra-terrestrial life could prove to be a tricky place for spacecraft to land, new research has revealed.
A team led by scientists from Cardiff University has predicted that fields of sharp ice growing to almost 15 metres [49 feet] tall could be scattered across the equatorial regions of Jupiter’s moon, Europa.
WASHINGTON (National Academies PR) – Despite significant cuts to NASA’s Planetary Science Division budget early in this decade, the space agency has made impressive progress in meeting goals outlined in the 2013-2022 planetary decadal survey by the National Academies of Sciences, Engineering, and Medicine, says a new midterm assessment from the National Academies.
The report notes that the agency met or exceeded the decadal survey’s recommendations for funding research and analysis, and for technology programs. However, NASA has not achieved the recommended timeline for New Frontiers and Discovery missions for the decade. At least one more New Frontiers mission and three Discovery missions should be selected before the end of the decade in order to achieve the schedule recommended in Vision and Voyages. (more…)
NASA has set mid-2022 for the second flight of the Space Launch System (SLS), but it’s not yet known what the massive booster will actually launch.
“Determination as to whether this launch will be SLS/Orion crewed mission (EM-2) or the SLS/Europa Clipper mission will be made based on risk and readiness of the Europa Clipper project,” according to a decision memo signed on Friday by William C. Hill, deputy associate administrator for Exploration Systems Development. Parabolic Arc obtained a copy of the memo.
PASADENA, Calif. (NASA PR) — 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.
NASA is working through technical issues with scientific instruments, solar arrays and power requirements as the space agency defines its ambitious Europa Clipper orbiter, according to a new Government Accountability Office (GAO) assessment.
Europa Clipper, which is set for launch in 2022, will be the space agency’s first dedicated mission to study Jupiter’s ice covered moon. Scientists believe the ice could hide a vast ocean teeming with extraterrestrial life.
Europa has long been a high priority for exploration because beneath its icy crust lies a salty, liquid water ocean. NASA’s Europa Clipper, targeted to launch in 2022, will be equipped with the instruments necessary to determine whether Europa possesses the ingredients necessary to support life as we know it.
Lori Glaze, acting director of NASA’s Planetary Science Division (PSD), and JoAnna Wendel, PSD communications lead, will host the chat. Guests include:
Xianzhe Jia, associate professor in the Department of Climate and Space Sciences and Engineering at the University of Michigan, Ann Arbor
Elizabeth Turtle, research scientist at Johns Hopkins Applied Physics Laboratory in Laurel, Maryland
Margaret Kivelson, professor emerita of Space Physics in the Department of Earth and Space Sciences at the University of California, Los Angeles
The public can send questions on social media by using #askNASA at any time during the event.
The Science Chat will occur as the scientific journal Nature Astronomy publishes a paper about how NASA’s Galileo spacecraft flew through a plumb of water from Europa a thousand kilometers (620 miles) thick. News of the paper had been embargoed by the journal, but Rep. John Culberson (R-Texas) revealed the finding during a subcommittee hearing last week.
