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.
WASHINGTON (NASA PR) — As NASA prepares to send astronauts back to the Moon and on to Mars, the agency’s quest to seek answers about our solar system and beyond continues to inform those efforts and generate new discoveries. The agency has extended the missions of two spacecraft, following an external review of their scientific productivity.
The missions — Juno and InSight — have each increased our understanding of our solar system, as well as spurred new sets of diverse questions.
WASHINGTON (NASA PR) — In 2020, NASA made significant progress on America’s Moon to Mars exploration strategy, met mission objectives for the Artemis program, achieved significant scientific advancements to benefit humanity, and returned human spaceflight capabilities to the United States, all while agency teams acted quickly to assist the national COVID-19 response.
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.
New lab experiments re-create the environment of Europa and find that the icy moon shines, even on its nightside. The effect is more than just a cool visual.
PASADENA, Calif. (NASA PR) — As the icy, ocean-filled moon Europa orbits Jupiter, it withstands a relentless pummeling of radiation. Jupiter zaps Europa’s surface night and day with electrons and other particles, bathing it in high-energy radiation. But as these particles pound the moon’s surface, they may also be doing something otherworldly: making Europa glow in the dark.
It looks as if the Trump Administration’s goal of landing astronauts on the moon in 2024 is expiring at about the same time as the administration itself. The fatal blow is being struck by Congress, not the incoming administration of President-elect Joe Biden.
The Senate Appropriations Committee has released a fiscal year 2021 funding bill that includes $1 billion for NASA to Human Landing System (HLS) that will take astronauts to and from the lunar surface as part of the Artemis program. The amount is far short of the $3.2 billion that NASA has said is needed for HLS to keep the 2024 landing on schedule.
A new decade of European exploration – to the Moon and Mars
Airbus to design and build the Earth Return Orbiter (ERO) for Mars Sample Return (MSR) campaign
ERO will reach Mars orbit, capture orbiting samples launched from the Red Planet and bring them back to Earth
TOULOUSE, 14 October 2020 (Airbus PR) – Airbus has been selected by the European Space Agency (ESA) as prime contractor for the Mars Sample Return’s Earth Return Orbiter (ERO) – the first ever spacecraft to bring samples back to Earth from Mars. Mars Sample Return (MSR) is a joint ESA-NASA campaign and the next step in the exploration of Mars. ERO and the Sample Fetch Rover (SFR) are the two main European elements of MSR, both are set to be designed and built by Airbus.
A manipulating arm, referred to as the Sample Transfer Arm (STA), that will transfer the samples from the SFR to the Mars Ascent Vehicle (MAV), is the third European contribution to the MSR program. The value of the ERO contract is €491 million [$574.8 million].
PASADENA, Calif. (NASA PR) — This video uses images from NASA’s Juno mission to recreate what it might have looked like to ride along with the Juno spacecraft as it performed its 27th close flyby of Jupiter on June 2, 2020.
During the closest approach of this pass, the Juno spacecraft came within approximately 2,100 miles (3,400 kilometers) of Jupiter’s cloud tops. At that point, Jupiter’s powerful gravity accelerated the spacecraft to tremendous speed – about 130,000 mph (209,000 kilometers per hour) relative to the planet.
Citizen scientist Kevin M. Gill created the video using data from the spacecraft’s JunoCam instrument. The sequence combines 41 JunoCam still images digitally projected onto a sphere, with a virtual “camera” providing views of Jupiter from different angles as the spacecraft speeds by.
The original JunoCam images were taken on June 2, 2020, between 2:47 a.m. PDT (5:47 a.m. EDT) and 4:25 a.m. PDT (7:25 a.m. EDT).
NASA’s Planetary Science Division (PSD) faces a series of managerial, financial and personnel challenges as it prepares to conduct a series of ever more ambitious missions to the moon and planets, according to a new audit by the space agency’s Office of Inspector General (IG).
PASADENA, Calif. (NASA PR) — Many exploration destinations in our solar system are frigid and require hardware that can withstand the extreme cold. During NASA’s Artemis missions, temperatures at the Moon’s South Pole will drop drastically during the lunar night. Farther into the solar system, on Jupiter’s moon Europa, temperatures never rise above -260 degrees Fahrenheit (-162 degrees Celsius) at the equator.

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.
