Greenbelt, Md. (NASA PR) — Several years ago, planetary scientist Lynnae Quick began to wonder whether any of the more than 4,000 known exoplanets, or planets beyond our solar system, might resemble some of the watery moons around Jupiter and Saturn.
Though some of these moons don’t have atmospheres and are covered in ice, they are still among the top targets in NASA’s search for life beyond Earth. Saturn’s moon Enceladus and Jupiter’s moon Europa, which scientists classify as “ocean worlds,” are good examples.

America is on the verge of a new era of space exploration, and America’s leadership in the space domain will be due to its courage to go and its conviction to stay. DOE, by many measures the “Department of Exploration,” is proud to be playing an essential part in rising to these challenges.
NASA and SpaceX recently launched American astronauts aboard an American rocket from American soil to the International Space Station for the first time since 2011, and America is actively planning to return to the Moon … and then go even further.
NASA’s Lucy mission to explore a group of Trojan asteroids orbiting in tandem with Jupiter remains on cost and schedule for a November 2021 launch, according to a new assessment from the Government Accountability Office (GAO).
NASA’s Europa Clipper orbiter could be placed in storage for two years awaiting a ride to Jupiter’s icy moon at a cost of $250 million due to Congress’ insistence that it be flown aboard the Space Launch System (SLS), according to a new review by the Government Accountability Office (GAO).
The cost estimate assumes that the Europa orbiter will be ready for launch in July 2023. It would be placed in storage until launch aboard a SLS in September 2025.
PASADENA, Calif. (NASA PR) — 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.

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.
WASHINGTON (NASA PR) — NASA has selected four Discovery Program investigations to develop concept studies for new missions. Although they’re not official missions yet and some ultimately may not be chosen to move forward, the selections focus on compelling targets and science that are not covered by NASA’s active missions or recent selections. Final selections will be made next year.
SAN ANTONIO, January 9, 2020 (SwRI PR) — Less than two years before launch, scientists associated with NASA’s Lucy mission, led by Southwest Research Institute, have discovered an additional small asteroid that will be visited by the Lucy spacecraft. Set to launch in 2021, its 12-year journey of almost 4 billion miles will explore the Trojan asteroids, a population of ancient small bodies that share an orbit with Jupiter.

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.
PASADENA, Calif. (NASA PR) — NASA will contribute an instrument to a European space mission that will explore the atmospheres of hundreds of planets orbiting stars beyond our Sun, or exoplanets, for the first time.
The instrument, called the Contribution to ARIEL Spectroscopy of Exoplanets, or CASE, adds scientific capabilities to ESA’s (the European Space Agency’s) Atmospheric Remote-sensing Infrared Exoplanet Large-survey, or ARIEL, mission.
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.
Despite early-stage robust funding, NASA is facing serious management and schedule challenges in its ambitious Europa Clipper program that will send an orbiter and lander to Jupiter’s ice covered moon beginning in 2023.
“Specifically, NASA’s aggressive development schedule, a stringent conflict of interest process during instrument selection, and an insufficient evaluation of cost and schedule estimates has increased project integration challenges and led the Agency to accept instrument cost proposals subsequently found to be far too optimistic,” the audit found.

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.
