Topic: Ganymede
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. ![]() This view of Jupiter’s atmosphere from NASA’s Juno spacecraft includes something remarkable, two storms caught in the act of merging.

NASA extends Juno, Insight missions
The missions – Juno and InSight – have each increased our understanding of our solar system, as well as spurred new sets of diverse questions. ![]() NASA has extended both the Juno mission at Jupiter through September 2025 (left) and the InSight mission at Mars through December 2022.

NASA reports ‘Great’ Conjunction of Jupiter, Saturn happens night of December 21st
In 1610, Italian astronomer Galileo Galilei pointed his telescope to the night sky, discovering the four moons of Jupiter – Io, Europa, Ganymede, and Callisto. In that same year, Galileo also discovered a strange oval surrounding Saturn, which later observations determined to be its rings. ![]() Saturn, top, and Jupiter, below, are seen after sunset from Shenandoah National Park, Sunday, Dec. 13, 2020, in Luray, Virginia. The two planets are drawing closer to each other in the sky as they head towards a “great conjunction” on December 21, where the two giant planets will appear a tenth of a degree apart.

NASA’s Juno Spacecraft gets first ever pictures of Jupiter’s Moon Ganymede
The only moon in the solar system that is larger than the planet Mercury, Ganymede consists primarily of water ice. Its composition contains fundamental clues for understanding the evolution of the 79 Jovian moons from the time of their formation to today. ![]() These images the JIRAM instrument aboard NASA’s Juno spacecraft took on Dec. 26, 2019, provide the first infrared mapping of Ganymede’s northern frontier. Frozen water molecules detected at both poles have no appreciable order to their arrangement and a different infrared signature than ice at the equator.

NASA establishes groundwork for exploration of the Moon, Mars in 2018NASA Headquarters
“Our agency’s accomplishments in 2018 are breathtaking. We’ve inspired the world and created incredible new capabilities for our nation,” Bridenstine said. “This year, we landed on Mars for the seventh time, and America remains the only country to have landed on Mars successfully.” ![]() NASA Administrator Jim Bridenstine, left, and Associate Administrator for the Science Mission Directorate Thomas Zurbuchen, right, join with representatives of nine U.S. companies that are eligible to bid on NASA delivery services to the lunar surface through Commercial Lunar Payload Services contracts Thursday, Nov. 29, 2018, at NASA Headquarters in Washington.

NASA’s Kepler Space Telescope identifies details of TRAPPIST-1h orbitsWritten by Michele Johnson
TRAPPIST-1 is only eight percent the mass of our sun, making it a cooler and less luminous star. It’s home to seven Earth-size planets, three of which orbit in their star’s habitable zone — the range of distances from a star where liquid water could pool on the surface of a rocky planet. The system is located about 40 light-years away in the constellation of Aquarius. The star is estimated to be between 3 billion and 8 billion years old. ![]() This artist’s concept shows TRAPPIST-1h, one of seven Earth-size planets in the TRAPPIST-1 planetary system. NASA’s Kepler spacecraft, operating in its K2 mission, obtained data that allowed scientists to determine that the orbital period of TRAPPIST-1h is 19 days.

NASA instruments approved for ESA JUpiter ICy Moons Explorer (JUICE) missionNASA Headquarters
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. «Read the rest of this article» Sections: Technology | No Comments
NASA continues to explore our Solar SystemWritten by Felicia Chou
As we wait for Juno’s first close-up images of Jupiter (to be taken August 27th during the spacecraft’s next pass by the planet), NASA continues to explore our solar system to help answer fundamental questions about how we came to be, where we are going and whether we are alone in the universe. «Read the rest of this article» Sections: Technology | No Comments
NASA’s Juno Spacecraft takes first pictures from Jupiter OrbitWritten by DC Agle / Preston Dyches
“This scene from JunoCam indicates it survived its first pass through Jupiter’s extreme radiation environment without any degradation and is ready to take on Jupiter,” said Scott Bolton, principal investigator from the Southwest Research Institute in San Antonio. “We can’t wait to see the first view of Jupiter’s poles.” ![]() This color view from NASA’s Juno spacecraft is made from some of the first images taken by JunoCam after the spacecraft entered orbit around Jupiter on July 5th (UTC).
