The bureaucracy of government control is slowly fading away in space exploration, at least in the US. A series of delays, cost overruns, and imposed requirements have finally started taking its toll on the Space Launch System (SLS), the next generation NASA rocket system. Now, the space agency has finally conceded a point to the commercial launch industry. It has elected to use Space X’s Falcon Heavy to launch one of its upcoming flagship missions – Europa Clipper.Continue reading “NASA Chooses Falcon Heavy Over SLS to Launch Europa Clipper, Saving About $2 Billion”
In the coming decade, NASA and the ESA will be sending two dedicated missions that will explore Jupiter’s moon Europa. These missions are known as the Europa Clipper and the JUpiter ICy moons Explorer (JUICE) missions, which will fulfill a dream that has been decades in the making – searching for possible evidence of life inside Europa. Since the 1970s, astronomers have theorized that this satellite contains a warm-water ocean that could support life.
The case for life in Europa has only been bolstered thanks to multiple flybys and observation campaigns that have been mounted since. According to new research led by the University of Hawaii at Manoa, the best way to look for potential signs of life (aka. biosignatures) would be to analyze small impact craters on Europa’s surface. These patches of exposed subsurface ice could point the way towards life that might exist deeper in the moon’s interior.Continue reading “Micrometeorites Churn up the Surface of Europa. If you Want to Find Life, You’ll Need to dig Down a Meter or So”
In about three years, NASA plans to launch a robotic orbiter that will study Jupiter’s mysterious moon Europa. It’s called the Europa Clipper mission, which will spend four years orbiting Europa to learn more about its ice sheet, interior structure, chemical composition, and plume activity. In the process, NASA hopes to find evidence that will help resolve the ongoing debate as to whether or not Europa harbors life in its interior.
Naturally, scientists are especially curious about what the Clipper mission might find, especially in Europa’s interior. According to new research and modeling supported by NASA, it’s possible that volcanic activity occurred on the seafloor in the recent past – which could be happening still. This research is the most detailed and thorough 3D modeling on how internal heat is produced and transferred and what effect this will have on a moon.Continue reading “There Might be Volcanoes at the Bottom of Europa’s sub-ice Oceans”
In a few years, NASA will be sending a spacecraft to explore Jupiter’s icy moon Europa. Known as the Europa Clipper mission, this orbiter will examine the surface more closely to search for plume activity and evidence of biosignatures. Such a find could answer the burning question of whether or not there is life within this moon, which is something scientists have speculated about since the 1970s.
In anticipation of this mission, scientists continue to anticipate what it will find once it gets there. For instance, scientists from NASA’s Jet Propulsion Laboratory recently conducted a study that showed how Europa might glow in the dark. This could be the result of Europa constantly being pummeled with high-energy radiation from Jupiter’s magnetic field, the study of which could tell scientists more about the composition of Europa’s ice.Continue reading “Europa’s Nightside Glows in the Dark”
In this decade and the next, some very impressive missions will take place. For instance, NASA will send its robotic Europa Clipper orbiter investigate Jupiter’s icy moon Europa for the first time. The orbiter will launch sometime in the middle of the decade (likely 2024) and arrive in the Jovian sytem in the 2030s to look for possible signs of life.
In preparation for this momentous event, NASA recently released a stunning new mission poster. As you can see, the poster features the orbiter looking down on Europa’s icy surface with Jupiter hanging in the background. The orbiter itself is in shadow so as to draw attention to the landscape beneath it.Continue reading “NASA Releases a New Poster for the Europa Clipper Mission”
At first glance, Jupiter’s moon Europa doesn’t seem much like Earth. It’s a moon, not a planet, and it’s covered in ice. But it does have one important thing in common with Earth: a warm, salty ocean.
Now there’s even more evidence that Europa’s sub-surface ocean is habitable.Continue reading “More Evidence that Europa’s Oceans Could be Habitable”
Earlier this week, we shared some stunning, newly reprocessed images of Europa from NASA’s Galileo spacecraft, which visited Jupiter and its moons from December 1995 to September 2003. Now, as scientists continue to revisit Galileo’s data, even more details are coming into focus about Jupiter’s enticing moon. Not only is there evidence within the past few years of geysers shooting from Europa’s surface, twenty years ago, Galileo may have also witnessed a cryovolcanic eruptions — or plumes of water — spewing from the icy moon.Continue reading “Even More Evidence that Europa has Geysers”
What’s been long-suspected has now been confirmed: Jupiter’s moon Europa has water. As we’ve learned more about the outer Solar System in recent years, Europa has become a high-priority target in the search for life. With this discovery, NASA has just painted a big red bulls-eye on Jupiter’s smallest Galilean moon.Continue reading “Water Vapor Was Just Found on Europa, More Evidence There’s Liquid Water Beneath All that Ice”
In 2023, NASA plans to launch the Europa Clipper mission, a robotic explorer that will study Jupiter’s enigmatic moon Europa. The purpose of this mission is to explore Europa’s ice shell and interior to learn more about the moon’s composition, geology, and interactions between the surface and subsurface. Most of all, the purpose of this mission is to shed light on whether or not life could exist within Europa’s interior ocean.
This presents numerous challenges, many of which arise from the fact that the Europa Clipper will be very far from Earth when it conducts its science operations. To address this, a team of researchers from NASA’s Jet Propulsion Laboratory (JPL) and Arizona State University (ASU) designed a series of machine-learning algorithms that will allow the mission to explore Europa with a degree of autonom.Continue reading “AI Could Help the Europa Clipper Mission Make New Discoveries!”
On August 19th, 2019, NASA announced that their Europa Clipper mission has been approved to move to the next phase of the mission, progressing to the final design stage.Continue reading “Exploring The Icy Moons of Jupiter. NASA’s Europa Clipper and ESA’s JUICE”
