For Cassini to achieve a resolution of 3 kilometers per pixel on any object, it must pass within half a million kilometers. It was discovered in 2004, and in 2012 was imaged more closely by the Cassini orbiter probe. I have no idea if this is realistic, but I'm imagining that if I approached it relatively slowly (at kilometers per hour rather than kilometers per second speed), my momentum might carry me right into and even through the moon.

its cameras mainly on objects relatively close to Saturn; the bright rings complicate moon-hunting efforts. Methone Methone is a small (3-kilometer) moon of Saturn that orbits between Mimas and Enceladus near Anthe and Pallene. Solar System → Local Interstellar Cloud → Local Bubble → Gould Belt → Orion Arm → Milky Way → Milky Way subgroup → Local Group → Local Sheet → Virgo Supercluster → Laniakea Supercluster → Observable universe → UniverseEach arrow (→) may be read as "within" or "part of". Cassini Photo of Saturn Moon Methone. Pallene shares its orbit with a faint dust ring around Saturn, now called the Pallene Ring. Many of the moons are very small: 33 are less than 10 km (6 mi) in diameter and thirteen moons are less than 50 km (31 mi). Dragonfly is a NASA mission to deliver a rotorcraft to Saturn’s moon Titan to advance our search for the building blocks of life. Second, all five moons may be the remains of a larger swarm that traveled in that area close to Saturn.

Just outside the orbit of Titan is Hyperion – the outermost of the inner 23 regular moons. Phillips Davis Thus we then have a c In 2065, there are colonies on Mars and privately owned tiny spacecraft are exploring the solar system. It’s not a matter of if, but when. Guiding that effort are NASA test directors, or NTDs. Methone is really shockingly round. The Cassini–Huygensspacecraft has made two visits to Methone and its closest approach was made on May 20, 2012 with a minimum distance of 1,900 km from it.

Become a member of The Planetary Society and together we will create the future of space exploration.

The surface gravity of the said item is 0.00023. Methone was first seen by the Cassini Imaging Team[1][5][6] and given the temporary designation S/2004 S 1.

Because these three tiny moons (Methone, Pallene and Anthe) orbit at very similar distances from Saturn, they are in a dynamical relationship. Learn how our members and community are changing the worlds. There's no register feature and no need to give an email address if you don't need to.

Cassini might collect some indirect clues by analysing the ring arc material, but it is unlikely to come close to the moon again before the mission ends in 2017. That isn't too hard. Its mass is estimated/calculated at being 8,992,010,598,583 kg. Earth-based tele-scopes focus on the outer part of the Saturn system, and have found a number of moons in the outer regions. Social Media Lead: The Voyager imaging team asked for the photo to show Earth’s vulnerability — to illustrate how small, fragile and irreplaceable it is on a cosmic scale. Methone is a small moon of Saturn. Its volume is 17. Its density has been calculated at being 0.5. The rocket booster segments that will help power NASA’s first Artemis flight test mission around the Moon arrived at KSC. Cassini captured high-resolution views of it on 20 May 2012.

Its eccentricity also varies on different timescales between 0.0011 and 0.0037, and its inclination between about 0.003° and 0.020°. This short article about science can be made longer. It is possible that such fluffy stuff can flow, at least on timescales of thousands or millions of years, to erase any crater scars. [6], Assuming that Methone is in hydrostatic equilibrium, i.e. Overcome by grief, the seven daughters threw themselves into the sea to die, but the goddess Amphitrite took pity on them and transformed them into halcyons or kingfishers.

The Other Inner Moons. NASA's Cassini spacecraft captured a picture of the tiny, 4-kilometer-wide (3-mile-wide) moon Pallene, in front of the planet Saturn. Like everything else seen for the first time in the Saturn system, Methone's appearance is a surprise. Something similar has probably happened to two other moons of Saturn, the flying-saucer-shaped Atlas and Pan. Guiding that effort are NASA test directors, or NTDs. Saturn’s ten largest moons compared to Earth’s moon.

Some worlds have enough internal heat to create lava flows and other volcanic events that can fill in craters, and a few boast rain or strong winds to erode away evidence of the impacts.

This blood was spilled when Uranus' son – and Alkyoneus' brother – Kronus castrated his father. Each of Saturn’s moons bears a unique story. NASA's next giant leap may be aided by tiny lunar robots that would help scout the lunar surface.

The same day, the NASA spacecraft also imaged Tethys, a 1,062-kilometers (660-mile) wide moon of Saturn… This image of Saturn was taken by NASA's Hubble Space Telescope on July 4, 2020, when the planet was 839 million miles from Earth. After the discovery in 2004, scientists realized that Pallene had possibly been first photographed on August 23, 1981, by the space probe Voyager 2. Methone was first seen by the Cassini Imaging Team [1] [5] [6] and given the temporary designation S/2004 S 1.Methone is also named Saturn XXXII (32). Material from Saturn’s rings seems to have piled up around each moon’s equator. Saturn is more than 120,000 kilometers (75,000 miles) wide at its equator. Gender. Methone was discovered on 1 June 2004 by S. Charnoz, C. Porco, Cassini Imaging Team.

Image Credit: NASA/JPL/SSI. NASA's Mars Odyssey spacecraft has captured these six infrared views of the Martian moon Phobos. Methone. Cassini obtained its first high-resolution images of Methone on May 20, 2012. The Cassini–Huygens spacecraft has made two visits to Methone and its closest approach was made on May 20, 2012 with a minimum distance of 1,900 km from it..

Scientists have two theories to explain the presence of Methone and two other tiny sister moons, Pallene and Anthe. Are you in? Fun — and even educational — NASA activities to do at home.

Here are instructions on how to enable JavaScript in your web browser. [11] The moons Pallene and Aegaeon are thought to be similarly smooth. NASA's Lunar Flashlight, a briefcase-sized satellite, or CubeSat, will detect surface ice believed to be at the bottom of craters on the Moon that have never been exposed to sunlight. Meet NASA's latest Mars Rover: Will Perseverance find life in 2021? Despite the moon being discovered in 1789, it wasn’t until 1847 that the name Mimas was given to it to avoid confusion after additional moons around Saturn were discovered. Pan Prometheus Atlas Calypso Helene Epimetheus Hyperion Science Writer: Pallene and nearby Methone were the first moons discovered in Cassini images. © 2020 The Planetary Society. Phillips Davis Here are Five Reasons, 10 Things You Might Not Know About Voyager's Famous 'Pale Blue Dot' Photo, 10 Things Spitzer Taught Us About Our Solar System. "We're changing the world. The name Methone was approved by the IAU Working Group on Planetary System Nomenclature on January 21, 2005. Here are five reasons Saturn's largest moons is so enticing.

That makes Methone’s smooth exterior a puzzle. Covid-19 news: Rise in infections in England may be slowing, Electronic blood vessels could replace damaged arteries, Why we're in for a long wait to hear from intelligent aliens.

There also will be a partial penumbral eclipse of the Moon. Pallene has been determined to be the same object spotted in a single image taken by NASA's Voyager spacecraft in the 1980s, at that time known as S/1981 S14. Whether you're doing it for the nerd cred or the pie, this week on #10Things, we've got all the ways you can celebrate #PiDay with NASA.
