A concept in development at NASA’s Jet Propulsion Laboratory would allow potential planetary missions to chase interesting clues in subsurface oceans.
PASADENA, Calif. (NASA PR) — Someday, a swarm of cellphone-size robots could whisk through the water beneath the miles-thick icy shell of Jupiter’s moon Europa or Saturn’s moon Enceladus, looking for signs of alien life. Packed inside a narrow ice-melting probe that would tunnel through the frozen crust, the tiny robots would be released underwater, swimming far from their mothercraft to take the measure of a new world.
Science instruments and other hardware for the spacecraft will come together in the mission’s final phase before a launch to Jupiter’s icy moon Europa in 2024.
PASADENA, Calif. (NASA PR) — When it’s fully assembled, NASA’s Europa Clipper will be as large as an SUV with solar arrays long enough to span a basketball court – all the better to help power the spacecraft during its journey to Jupiter’s icy moon Europa. And just about every detail of the spacecraft will have been hand-crafted.
WASHINGTON (NASA PR) — In 2021, NASA completed its busiest year of development yet in low-Earth orbit, made history on Mars, continued to make progress on its Artemis plans for the Moon, tested new technologies for a supersonic aircraft, finalized launch preparations for the next-generation space telescope, and much more – all while safely operating during a pandemic and welcoming new leadership under the Biden-Harris Administration.
How do we understand the significance of new scientific results related to the search for life? When would we be able to say, “yes, extraterrestrial life has been found?”
NASA scientists are encouraging the scientific community to establish a new framework that provides context for findings related to the search for life. Writing in the journal Nature, they propose creating a scale for evaluating and combining different lines of evidence that would ultimately lead to answering the ultimate question: Are we alone in the universe?
Take a closer look at the complex choreography involved in building NASA’s Europa Clipper as the mission to explore Jupiter’s moon Europa approaches its 2024 launch date.
PASADENA, Calif. (NASA PR) – The hardware that makes up NASA’s Europa Clipper spacecraft is rapidly taking shape, as engineering components and instruments are prepared for delivery to the main clean room at the agency’s Jet Propulsion Laboratory in Southern California. In workshops and labs across the country and in Europe, teams are crafting the complex pieces that make up the whole as mission leaders direct the elaborate choreography of building a flagship mission.
KENNEDY SPACE CENTER, Fla. (NASA PR) — NASA has selected Space Exploration Technologies Corp. (SpaceX) of Hawthorne, California, to provide launch services for Earth’s first mission to conduct detailed investigations of Jupiter’s moon Europa.
Jupiter’s moon Europa and its global ocean may currently have conditions suitable for life. Scientists are studying processes on the icy surface as they prepare to explore.
PASADENA, Calif. (NASA PR) — It’s easy to see the impact of space debris on our Moon, where the ancient, battered surface is covered with craters and scars. Jupiter’s icy moon Europa withstands a similar trouncing – along with a punch of super-intense radiation. As the uppermost surface of the icy moon churns, material brought to the surface is zapped by high-energy electron radiation accelerated by Jupiter.
NASA FACT SHEET FY 2022 Budget Request Science ($ Millions)
NASA’s Science budget, managed by the Science Mission Directorate, includes five major science areas as well as the James Webb Space Telescope which is funded separately from Astrophysics. These areas include:
Earth Science to enhance understanding of Earth systems and to observe the effects of climate change. The Budget invests heavily in climate and applications research, begins formulation of the first four Designated Observable missions, and initiates the Earth System Explorers program (consistent with Decadal Survey recommendations). The Budget also supports the ongoing development of the Earth System Observatory including PACE, CLARREO Pathfinder, NISAR, SWOT, and Landsat 9.
Jupiter’s moon Europa has an icy crust covering a vast, global ocean. The rocky layer underneath may be hot enough to melt, leading to undersea volcanoes.
PASADENA, Calif. (NASA PR) — New research and computer modeling show that volcanic activity may have occurred on the seafloor of Jupiter’s moon Europa in the recent past – and may still be happening. NASA’s upcoming Europa Clipper mission, targeting a 2024 launch, will swoop close to the icy moon and collect measurements that may shed light on the recent findings.
Jupiter’s moon Europa may have the potential to harbor life. The spacecraft will use multiple flybys of the moon to investigate the habitability of this ocean world.
PASADENA, Calif. (NASA PR) — Europa Clipper, NASA’s upcoming flagship mission to the outer solar system, has passed a significant milestone, completing its Critical Design Review. During the review, experts examined the detailed design of the spacecraft to ensure that it is ready to complete construction. The mission is now able to complete hardware fabrication and testing, and move toward the assembly and testing of the spacecraft and its payload of sophisticated science instruments.
In a blow to Space Launch System (SLS) backers, NASA has issued a request for information (RFI) for the October 2024 launch of the Europa Clipper orbiter that will search for signs of life on Jupiter’s enigmatic, ice-covered moon Europa.
It’s a clear sign that NASA is seeking commercial alternatives to launching the spacecraft on SLS. Congress had previously mandated by law that Europa Clipper’s orbiter and a follow-up lander be launched on the massive rocket. However, the most recent spending law stipulated that NASA should use SLS if one is available.
The spacecraft, which has been gathering data on the gas giant since July 2016, will become an explorer of the full Jovian system – Jupiter and its rings and moons.
PASADENA, Calif. (NASA PR) — NASA has authorized a mission extension for its Juno spacecraft exploring Jupiter. The agency’s most distant planetary orbiter will now continue its investigation of the solar system’s largest planet through September 2025, or until the spacecraft’s end of life. This expansion tasks Juno with becoming an explorer of the full Jovian system – Jupiter and its rings and moons – with multiple rendezvous planned for three of Jupiter’s most intriguing Galilean moons: Ganymede, Europa, and Io.
Scientists have theorized on the origin of the water plumes possibly erupting from Jupiter’s moon Europa. Recent research adds a new potential source to the mix.
PASADENA, Calif. (NASA PR) — Plumes of water vapor that may be venting into space from Jupiter’s moon Europa could come from within the icy crust itself, according to new research. A model outlines a process for brine, or salt-enriched water, moving around within the moon’s shell and eventually forming pockets of water – even more concentrated with salt – that could erupt.
