NASA Europa Clipper to carry unique message to Jupiter’s moon, packed with Earth’s essence

[ad_1] In a celestial nod to human creativity and curiosity, NASA is set to launch its Europa Clipper spacecraft in October, bound for Jupiter's moon Europa. Nestled within the spacecraft is a symbolic message, marking a departure from NASA's longstanding tradition of sending inspirational dispatches into the cosmos.The heart of this cosmic artefact is a triangular metal plate, approximately 7 by 11 inches, constructed from tantalum. Adorning its surface is an engraving of U.S. Poet Laureate Ada Limón's handwritten "In Praise of Mystery: A Poem for Europa." This poetic tribute is accompanied by a silicon microchip stencilled with over 2.6 million names submitted by the public, forming the centrepiece of an illustration depicting a bottle amid the Jovian system- a tribute to NASA's "Mess...

NASA’s Juno mission sheds new light on Jupiter moon Europa’s oxygen production rate

[ad_1] NASA's Juno mission to Jupiter has revealed intriguing insights into the rate of oxygen production on Europa, one of the gas giant's moons. Published in Nature Astronomy on March 4, the study indicates that the rate of oxygen production at Europa is considerably lower than previously thought. Utilizing data collected by Juno's Jovian Auroral Distributions Experiment (JADE) instrument, scientists estimated the production rate to be around 26 pounds (12 kilograms) per second, challenging earlier estimates ranging from a few pounds to over 2,000 pounds per second.Europa, with its potential subsurface ocean beneath its icy crust, has long fascinated researchers for its potential to harbor life-supporting conditions. The moon's location within Jupiter's radiation belts is crucial, as ...

ET Life? NASA discovers potential extraterrestrial oceans on 17 far-off exoplanets

[ad_1] In a groundbreaking study, NASA has unveiled a revelation that expands the search for extraterrestrial life. Researchers have identified 17 exoplanets positioned beyond our solar system that might boast subsurface oceans beneath their icy exteriors. The intriguing aspect lies in the possibility of periodic eruptions, resembling geysers, breaking through the frozen crusts of these distant worlds. Subsurface OceansThe research, conducted by scientists at NASA's Goddard Space Flight Center, included a meticulous analysis of geyser activity on these exoplanets. Remarkably, two of these celestial bodies are within observational reach of telescopes, presenting an unprecedented opportunity to witness these icy eruptions. This discovery holds paramount significance as the subsurface ocea...

NASA Astronomy Picture of the Day 20 May 2023: STUNNING view of Jupiter’s Moon Europa

[ad_1] Jupiter is the second planet in our solar system with the most number of moons at 95! Among these, the smallest of Jupiter's four Galilean moons is Europa which is the sixth closest to the planet. Europa is said to be about 90 percent the size of Earth's Moon! If we were to replace our Moon with Europa, it would have a similar apparent size in the sky, but it would be significantly brighter, NASA explains. This is because Europa's surface is composed of water ice that reflects approximately 5.5 times more sunlight than our Moon does. Interestingly, Europa is a popular destination as it has been visited by several spacecraft and more missions are planned in the future. Today's NASA Astronomy Picture of the Day even brings a stunning view of Europa by Galileo spacecraft. However, t...

Simply AWESOME! JUICE spacecraft snaps selfie with Earth in background

[ad_1] Just a week ago, the European Space Agency's first ever Jupiter mission took off from ELA-3 in Europe's Spaceport in Kourou, French Guiana. The mission, named Jupiter Icy Moons Explorer or JUICE, is being led by the European Space Agency (ESA). The spacecraft will study three of Jupiter's Galilean moons — Ganymede, Callisto, and Europa — in search of water and signs of life on them. The spacecraft shot into space on the Ariane 5 rocket. Interestingly, the spacecraft took 'selfies' while leaving Earth behind.ESA released 'selfies' taken by the JUICE spacecraft shortly after liftoff, with Earth in the background. According to ESA, the images were captured just hours following the April 14 launch, with the help of body-mounted cameras, which are to be used to monitor the deployment ...

European spacecraft on way to Jupiter and its icy moons

[ad_1] A European spacecraft rocketed away Friday on a decadelong quest to explore Jupiter and three of its icy moons that could hold buried oceans.The journey began with a perfect morning liftoff by Europe's Ariane rocket from French Guiana on the coast of South America. But there were some tense minutes later as controllers awaited signals from the spacecraft. When contact finally was confirmed close to an hour into the flight, Mission Control in Germany declared: “The spacecraft is alive!” It will take the robotic explorer, dubbed Juice, eight years to reach Jupiter, where it will scope out not only the solar system's biggest planet but also Europa, Callisto and Ganymede. The three ice-encrusted moons are believed to harbor underground oceans, where sea life could exist.Then in perha...

Pleiades Neo satellite snaps awesome snapshot of Jupiter, 4 moons

[ad_1] One of Europe's flagship satellites has captured Jupiter and its largest Moon, Ganymede. Jupiter is the fifth planet in the solar system, and it is by far the biggest one. In fact, it is twice as big as all the other planets in our solar system combined. Jupiter is also known as the Gas Giant due to a dense atmosphere of hydrogen and helium with windy clouds of ammonia. It also has the most moons in the solar system, with 92 confirmed moons with orbits, according to International Astronomical Union's Minor Planet Center. In fact, Jupiter is also referred to as a failed sun-it just could not get big enough.Jupiter and its moons capturedThe picture captured shows Jupiter with Ganymede orbiting it in close proximity. Moreover, its other moons such as Callisto and Europa can be seen ...

First-ever Jupiter mission for ESA, JUICE set to go live today; Check time, how to watch online

[ad_1] In just a few hours from now, the first-ever Jupiter mission for Europe will take off. The mission, which is called the Jupiter Icy Moons Explorer (JUICE), is being led by the European Space Agency (ESA). The spacecraft will study three of Jupiter's Galilean moons — Ganymede, Callisto, and Europa — in search of water and signs of life on them. The spacecraft will take about seven and a half years to reach the gas giant and will begin its exploration in 2031. If you want to know the time of the JUICE mission launch and how to watch it live online, check the details below.The ESA JUICE mission is set to launch on April 13 at 1215 GMT (8:15 AM EDT, 5:45 PM IST).

Jupiter’s moons habitable? NASA’s Clipper and ESA’s JUICE to find out

[ad_1] Jupiter's large icy moons hold numerous secrets which are still unexplored. ESA's JUICE spacecraft, short for Jupiter Icy Moons Explorer, is set to embark on a mission to visit the largest planet in our solar system. JUICE's journey to Jupiter will take a total of eight years, during which it will utilize gravitational assistance from Earth, Venus, and Mars to conserve fuel. While reaching Jupiter in July 2031, the spacecraft powered by the sun will use its 10 science instruments to investigate three of the four largest moons orbiting the giant planet - Europa, Ganymede, and Callisto - all believed to possess subsurface oceans, Scientific American reported. However, among these moons, ESA's JUICE will primarily focus on Ganymede, which happens to be the largest moon i...

Wow! NASA finds water on Jupiter’s Europa moon; life possible?

[ad_1] The latest study suggests that the presence of water on Jupiter’s Moon Europa makes it habitable. Jupiter has four Galilean moons - Io, Europa, Ganymede, and Callisto. And in a surprising development, NASA's scientists have found water on the surface of one of the smallest of the four Galilean moons orbiting Jupiter. This study has been published in the Planetary Science Journal, which revealed that water exists on the icy crust of Europa moon of Jupiter. This also hints at the possibility of accessible liquid water bodies in the outer solar system. This also makes way for an important path of exploration of life beyond Earth.The study suggests that the water could be close to the surface of Europa at about 4 to 8 kilometers, which generally holds coldest and brittle ice.
