TITAN (SATURN MOON)

Dragonfly is a proposed mission concept to send a rotorcraft-lander to Saturn’s large, exotic moon, Titan. Designed to sample surface materials and determine composition in different settings, this revolutionary mission concept offers the capability to explore diverse locations and characterize the habitability of Titan’s environment, investigate the progression of prebiotic chemistry, and even to search for chemical hints of water-based or hydrocarbon-based life. The Dragonfly dual-quadcopter would fly to dozens of sites, tens to hundreds of miles apart. Titan’s dense, calm atmosphere and low gravity make flying ideal; the rotorcraft could travel from its initial landing site to explore areas several hundred miles away, though Dragonfly would spend most of its mission making science measurements on the ground. Led by the Johns Hopkins University Applied Physics Laboratory, Dragonfly is a finalist to become the next mission in NASA’s New Frontiers planetary science program. Key partners include Penn State University, NASA (Goddard Space Flight Center, Ames Research Center, Langley Research Center, Jet Propulsion Laboratory), Honeybee Robotics and Malin Space Science Systems. New Frontiers is managed by the Planetary Missions Program Office at NASA’s Marshall Space Flight Center in Huntsville, Alabama, for the agency’s Planetary Science Division in Washington.

Planetary scientist Dr. Ralph Lorenz of the Applied Physics Lab at Johns Hopkins University discusses the saturnian moon Titan and results of the Cassini mission’s exploration of Titan. Lorenz outlines the uniqueness of Titan’s geochemistry and surface morphology, but also points out its similarities with Earth. This was the fourth presentation in the Lunar and Planetary Institute’s 2017–2018 Cosmic Exploration Speaker Series, “Diving into Ocean Worlds.”

Scientists have thought for awhile that pulsars could be used as a sort of galactic positioning system, and astronomers have published the most advanced topographical map of Titan to date! ---------- Support SciShow by becoming a patron on Patreon: https://www.patreon.com/scishow ---------- Dooblydoo thanks go to the following Patreon supporters: Kelly Landrum Jones, Sam Lutfi, Kevin Knupp, Nicholas Smith, D.A.

Cassini’s mission to the Saturn system is coming to an end, but the space probe has uncovered chemical mysteries on the moon Titan that will keep scientists busy for years to come. ↓↓More info and references below↓↓ When the Cassini space probe launched 20 years ago, planetary scientists knew that Saturn’s moon Titan showcased some complex atmospheric chemistry. But now that Cassini has had a closer look at the moon, researchers are shocked just by just how gnarly that chemistry is. In this episode of Speaking of Chemistry, we teamed up with Eos reporter JoAnna Wendel to learn how studying Titan’s atmosphere is teaching us more about our solar system and even our home planet. Sarah Hörst is a member of Eos’s editorial advisory board. Want to continue your magical mystery tour of Titan? Check out these articles.

In 2001, Saturn's ridiculously huge moon Titan passed directly in front of a binary star, occulting (as astronomers call it) both stars. Titan has an atmosphere, and as it passed through it the light from the stars got bent, appearing as a dot that whips around the moon's edge. Note the second star has two bright spots that do this, too. This phenomenon tells us a lot about the density, temperature, and pressure of Titan's atmosphere. The total elapsed time in the video is about 30 minutes.

Saturn’s giant, hazy moon Titan has been essential to NASA’s Cassini mission during its 13 thrilling years of exploration there. Cassini and the European Huygens probe have revealed a fascinating world of lakes and seas, great swaths of dunes, and a complex atmosphere with weather – with intriguing similarities to Earth. Titan has also been an engine for the mission, providing gravity assists that propelled the spacecraft on its adventures around the ringed planet.

Alien life potentially forming on Saturn’s Moon. Alien life has been a constant topic of debate for many centuries. Some believe we have already been visited by extraterrestrial life, and others believe that notion of aliens existing is pure fantasy. However, with our universe expanding as fast as the speed of light, there has to be something other than us out there right? Recent scientific findings suggest we may have found evidence of otherworldly life in our own solar system. Watch the video to learn more. Do you think alien life is forming on Titan?

Europa is fine and all, but where we really need to go is Saturn's moon Titan. Let's look at some cool ideas for probes to fully explore this world.

If all goes well, the Europa Clipper will blast off for the world in the 2020s, and orbit the icy moon to discover all its secrets. And that’s great and all, I like Europa just fine. But you know where I’d really like us to go next? Titan. Titan, as you probably know, is the largest moon orbiting Saturn. In fact, it’s the second largest moon in the Solar System after Jupiter’s Ganymede. It measures 5,190 kilometers across, almost half the diameter of the Earth. This place is big. It orbits Saturn every 15 hours and 22 days, and like many large moons in the Solar System, it’s tidally locked to its planet, always showing Saturn one side. Before NASA’s Voyager spacecraft arrived in 1980, astronomers actually thought that Titan was the biggest moon in the Solar System. But Voyager showed that it actually has a thick atmosphere, that extends well into space, making the true size of the moon hard to judge. This atmosphere is one of the most interesting features of Titan. In fact, it’s the only moon in the entire Solar System with a significant atmosphere. If you could stand on the surface, you would experience about 1.45 times the atmospheric pressure on Earth. In other words, you wouldn’t need a pressure suit to wander around the surface of Titan. You would, however, need a coat. Titan is incredibly cold, with an average temperature of almost -180 Celsius. For you Fahrenheit people that’s -292 F. The coldest ground temperature ever measured on Earth is almost -90 C, so way way colder. You would also need some way to breathe, since Titan’s atmosphere is almost entirely nitrogen, with trace amounts of methane and hydrogen. It’s thick and poisonous, but not murderous, like Venus. Titan has only been explored a couple of times, and we’ve actually only landed on it once. The first spacecraft to visit Titan was NASA’s Pioneer 11, which flew past Saturn and its moons in 1979. This flyby was followed by NASA’s Voyager 1 in 1980 and then Voyager 2 in 1981. Voyager 1 was given a special trajectory that would take it as close as possible to Titan to give us a close up view of the world. Voyager was able to measure its atmosphere, and helped scientists calculate Titan’s size and mass. It also got a hint of darker regions which would later turn out to be oceans of liquid hydrocarbons. The true age of Titan exploration began with NASA’s Cassini spacecraft, which arrived at Saturn on July 4, 2004. Cassini made its first flyby of Titan on October 26, 2004, getting to within 1,200 kilometers or 750 miles of the planet. But this was just the beginning. By the end of its mission later this year, Cassini will have made 125 flybys of Titan, mapping the world in incredible detail. Cassini saw that Titan actually has a very complicated hydrological system, but instead of liquid water, it has weather of hydrocarbons. The skies are dotted with methane clouds, which can rain and fill oceans of nearly pure methane. And we know all about this because of Cassini’s Huygen’s lander, which detached from the spacecraft and landed on the surface of Titan on January 14, 2005. Here’s an amazing timelapse that shows the view from Huygens as it passed down through the atmosphere of Titan, and landed on its surface. Huygens landed on a flat plain, surrounded by “rocks”, frozen globules of water ice. This was lucky, but the probe was also built to float if it happened to land on liquid instead. It lasted for about 90 minutes on the surface of Titan, sending data back to Earth before it went dark, wrapping up the most distant landing humanity has ever accomplished in the Solar System. Although we know quite a bit about Titan, there are still so many mysteries. The first big one is the cycle of liquid. Across Titan there are these vast oceans of liquid methane, which evaporate to create methane clouds. These rain, creating mists and even rivers. Is it volcanic? There are regions of Titan that definitely look like there have been volcanoes recently. Maybe they’re cryovolcanoes, where the tidal interactions with Saturn cause water to well up from beneath crust and erupt onto the surface.

Cryovolcanoes are a lot like volcanoes here on Earth, except they erupt with ice and – so far – only found on frozen worlds.

Many weird and wonderful things have been discovered, but some of these findings have created new and perplexing mysteries. One such mystery is centered around Ceres' ice volcanoes - or lack thereof. Ice volcanoes, or cryovolcanoes, are features that are thought to be common on the surfaces of cold bodies in the outer solar system, creating ice analogs of the volcanoes we have on Earth." Lonely Ice Volcano On Ceres May Have Once Had Company http://www.space.com/35571-ceres-ice-volcano-ahuna-mons.html "Ahuna Mons could simply be a one-of-a-kind feature. But new research by Sori and his colleagues suggests another possible answer: Ahuna Mons may have once had company, older cryovolcanoes that flattened out and disappeared over the eons via a process called 'viscous relaxation.' Viscous relaxation means that many solids on a planetary surface will flow, given enough time. Earth's mountains don't relax in an appreciable way, because they're made of rock. But Ahuna Mons has a lot of water ice mixed in and is therefore a relaxation candidate, Sori said." Where is the Ice on Ceres? New NASA Dawn Findings https://www.nasa.gov/feature/jpl/where-is-the-ice-on-ceres-new-nasa-dawn-findings "At first glance, Ceres, the largest body in the main asteroid belt, may not look icy. Images from NASA's Dawn spacecraft have revealed a dark, heavily cratered world whose brightest area is made of highly reflective salts -- not ice. But newly published studies from Dawn scientists show two distinct lines of evidence for ice at or near the surface of the dwarf planet." ____________________ DNews is dedicated to satisfying your curiosity and to bringing you mind-bending stories & perspectives you won't find anywhere else!

The Huygens probe, supplied by the European Space Agency (ESA) and named after the 17th century Dutch astronomer who first discovered Titan, Christiaan Huygens, scrutinized the clouds, atmosphere, and surface of Saturn's moon Titan in its descent on January 15, 2005. It was designed to enter and brake in Titan's atmosphere and parachute a fully instrumented robotic laboratory down to the surface. The probe system consisted of the probe itself which descended to Titan, and the probe support equipment (PSE) which remained attached to the orbiting spacecraft. The PSE includes electronics that track the probe, recover the data gathered during its descent, and process and deliver the data to the orbiter that transmits it to Earth. The core control computer CPU was a redundant MIL-STD-1750A control system. The data were transmitted by a radio link between Huygens and Cassini provided by Probe Data Relay Subsystem (PDRS). As the probe's mission could not be telecommanded from Earth because of the great distance, it was automatically managed by the Command Data Management Subsystem (CDMS). The PDRS and CDMS were provided by the Italian Space Agency (ASI). Huygens communications would have been entirely lost if not for testing in flight that discovered a Doppler-related problem, requiring a change in orbital trajectories to compensate.

On Jan. 14, 2005, ESA's Huygens probe made its descent to the surface of Saturn's hazy moon, Titan. Carried to Saturn by NASA's Cassini spacecraft, Huygens made the most distant landing ever on another world, and the only landing on a body in the outer solar system. This video uses actual images taken by the probe during its two-and-a-half hour fall under its parachutes. Huygens was a signature achievement of the international Cassini-Huygens mission, which will conclude on Sept. 15, 2017, when Cassini plunges into Saturn's atmosphere.

On 15 October 1997, NASA's Cassini orbiter embarked on an epic, seven-year voyage to the Saturnian system. Hitching a ride was ESA's Huygens probe, destined for Saturn's largest moon, Titan. The final chapter of the interplanetary trek for Huygens began on 25 December 2004 when it deployed from the orbiter for a 22-day solo cruise toward the haze-shrouded moon. Plunging into Titan’s atmosphere, on 14 January 2005, the probe survived the hazardous 2 hour 27 minute descent to touch down safely on Titan’s frozen surface. This narrated movie, created with data collected by the Huygens Descent Imager/Spectral Radiometer (DISR), depicts the view from Huygens during the last few hours of this historic journey. This new version of the movie uses updated DISR data and was released on 14 January 2015 on the occasion of the 10th anniversary of Huygen's landing on Titan.

Enlarge ImageWelcome back to Titan, clouds. Saturn's massive moon Titan lost its northern cloud cover from around 2010 to 2014. NASA's Cassini spacecraft has been keeping an eye out for fresh cloud activity on Titan. According to NASA, "Cassini scientists noted a decrease in clouds everywhere on Titan after a large storm in 2010, and expected clouds to return sooner, based on computer models of Titan's atmosphere." Saturn has dozens of moons, but Titan is the largest and has been one of the most fascinating subjects of the Cassini mission. https://www.cnet.com/news/clouds-saturn-moon-titan-nasa-cassini/#ftag=CAD590a51e http://www.wochit.com This video was produced by YT Wochit News using http://wochit.com

Exploring what organisms on Titan might be like

It's a voyage of exploration like no other - to Titan, Saturn's largest moon and thought to resemble our own early Earth. For a small team of British scientists this would be the culmination of a lifetime's endeavour - the flight alone, some 2 billion miles, would take a full seven years. This is the story of the space probe they built, the sacrifices they made and their hopes for the landing. Would their ambitions survive the descent into the unknown on Titan's surface? ** I do not own nor claim copyright on this material. This is just for education purposes.

A NASA news release describes the presence of deep, liquid-filled canyons on Saturn’s moon Titan; the discovery was made during a May 2013 flyover by the Cassini spacecraft. The Cassini spacecraft has located a unique geological feature on Saturn’s moon Titan.  A recent NASA news release describes the structure as “deep, steep-sided canyons... that are flooded with liquid hydrocarbons.”  The article goes on to state that, “The finding represents the first direct evidence of the presence of liquid-filled channels on Titan, as well as the first observation of canyons hundreds of meters deep.”  Cassini made the observation during a May 2013 flyover which focused on the area around Titan’s sea, Ligeia Mare.  Based on the collected data, astronomers have determined that the adjacent channels are actually  canyons estimated to be less than half a mile wide and 790 to 1,870 feet deep. These channels are believed to contain liquid due to their dark coloring on radar images.  The research team also suspects that the deep cuts in the terrain were likely created by prolonged geologic activity or by faster erosion compared to other areas.  The plan going forward is to continue studying Titan’s other channels in addition to its overall landscape.

One day it will be an amazing scientific accomplishment when we colonize and bring life to a moon like Saturn's icy Enceladus. Subscribe for new videos weekly! 5. Triton Photographs and data sent back from the Voyager 2 spacecraft back in August of 1989 showed that the surface of Triton, Neptune’s largest moon, was made up of nitrogen ice and rock. The suspicion of liquid water being hidden beneath the surface was raised. Even though the moon has an atmosphere, it would be pretty much the same as if it didn’t have one because of how thin it is. The average temperature on the moon is an unbelievable -391 degrees Fahrenheit, making it the coldest body in the entirety of our solar system. 4. Mimas Also known as the “Death Star” moon and for good reason. Mimas is one of Saturn’s icy and rocky moons. Mimas might have an ocean located beneath its cold and unwelcoming -looking surface, which may possibly be better adapted for life. Close study of the Cassini footage by scientists shows that Mimas looks to rock back and forth as it went around on its orbit. This could imply activity underneath its surface. However, scientists were very wary with what they found, stating that there hadn’t been any other signs that point to geological activity. They merely stated that if an ocean was discovered, the moon could definitely be a candidate for being colonized. It’s believed that the theoretical ocean would be about 15 to 18 miles below the surface. If the rocking movement that supports this theory of an ocean proves to be false, then the movement is mostly likely because of a misshapen core due to the strong gravitational pull caused by Saturn’s rings 3. Callisto Exactly the same size as the planet Mercury, Callisto is Jupiter’s second largest moon that looks like it has a large liquid ocean hidden within its icy surface. The surface of Callisto mainly made up of craters and what are basically fields of ice. Callisto also has a relatively thin atmosphere consisting of carbon dioxide. Research that already been performed has suggested that this atmosphere is being filled up again and again by carbon dioxide that is released from below the surface because it is too thin to stay in place. Collected data implies the chance that oxygen could also be actively present inside of the atmosphere, but there would need to be further tests to confirm if this theory holds true. Callisto is positioned in a safe enough space from Jupiter that the giant planet’s radiation levels would be very mild. 2. Ganymede Ganymede happens to be Jupiter’s largest moon and like other masses, in our solar system, it could potentially prove to have water trapped underneath its surface. If you were to compare it to other ice-covered moons, Ganymede’s surface is believed to be relatively thin and should be much easier to break through. This moon also happens to be the only moon with its own gravitational field that creates its own auroras, like the ones that are produced here on earth. Their pattern in movement also leads scientists to theorize there is an ocean trapped underneath the surface. Because of Ganymede’s thin oxygen atmosphere, it is too thin to support our life but maybe enough to support terraforming. Back in 2012, the European Space Agency got the okay to go ahead and launch a mission to go and explore Ganymede and two other of Jupiter’s moons, Europa and Callisto. The operation is scheduled to launch in 2022 and reach the moon 10 years later. Out of the three moons to be explored, scientists believe that Ganymede will have the best environment to study and potentially support life, if possible. 1. The Moon The first moon that mankind would colonate would, of course, be the earth’s very own moon. It’s been described as a good “dress rehearsal” for potential colonization missions in the future because of how close it is to earth compared to all the other moons. Earlier in March of this year, there was a story that was going around that this type of operation could be carried out within the next 10 years or so. NASA astrobiologist Chris McKay is one of the individuals whose onboard with making this mission come to fruition. His opinion is that other missions to the moon have failed because of the high cost, but his team has a plan that requires little compared to previous missions. Although NASA’s current focus is to get humans to land on Mars, McKay says that that won’t come to light until they can first get to the moon and set up permanent bases there first.

According to a new study by scientists at Cornell University, life might exist beyond the bounds of water-based chemistry on Saturn' s largest moon Titan. Titan is a very cold place. Instead of water on the surface, it is filled with liquid methane and ethane. Its dense atmosphere, a yellow haze, is full of nitrogen and methane. When sunlight hits this toxic atmosphere, the reaction produces hydrogen cyanide. Prior studies indicated that on Titan's surface, HCN can react to form long chains, or polymers, one of which called polyimine. Researchers have revealed that under Titan-like cold environmental conditions, polyimine is flexible and can absorb the sun' s energy and become a possible catalyst for life.

Researchers from Cornell University say Earth and Saturn’s moon Titan may have a surprising similarity – the ability to support life.
