Jupiter and its moons orbit about 484 million miles (778 million kilometers) from our Sun.
A research team led out of NASA’s Goddard Space Flight Center has detected water vapor for the first time above Europa’s surface.
Callisto is 2.6 times smaller than Earth, and it’s about 289 times smaller than our Sun. 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. NASA's Mars 2020 Perseverance rover mission is on its way to the Red Planet to search for signs of ancient life and collect samples to send back to Earth. The surface is about 4 billion years old and it’s been pummeled, likely by comets and asteroids. Callisto looks like it’s sprinkled with bright white dots that scientists think are the peaks of the craters capped with water ice.Scientists announced in 1999 that the Galileo spacecraft detected a very thin carbon dioxide exosphereCallisto is on the list of possible places where life could exist in our solar system beyond Earth. Its icy surface is billions of years old, lacks any sign of volcanic activity, and is densely covered with rifts and craters. It’s also a deathtrap crawling with giant caterpillars.Callisto gets a mention in Robert A. Heinlein's 1950 novel “Farmer in the Sky.” The book is mostly about Jupiter’s moon Ganymede, but it discusses an atmosphere being created so colonists can live on Callisto.Philip K. Dick, author of “Blade Runner” and “The Minority Report” wrote a short story in 1955 called “The Mold of Yancy” about colonists living in a totalitarian society on Callisto.Lin Carter created a series of eight books in the 1970s called the Callisto series. Callisto orbits about 1,170,000 Callisto orbits about 1,170,000 miles (1,883,000 kilometers) from Jupiter and it takes about 17 (16.689) Earth days for Callisto to complete one orbit of Jupiter.
Callisto is Jupiter’s second largest moon after Ganymede and it’s the third largest moon in our solar system. NASA's next giant leap may be aided by tiny lunar robots that would help scout the lunar surface. Data gathered by the Galileo spacecraft indicate Callisto may have a subsurface ocean and scientists estimate it may be 155 miles (250 kilometers) below the surface. NASA has taken the next steps toward building Space Launch System (SLS) solid rocket boosters for as many as six additional flights. Callisto is an enormous bear empowered by the corruption of the Wilderness that resides south of the Demonic Ruins and is the only monster to drop the tyrannical ring. NASA has selected four Discovery Program investigations to develop concept studies for new missions. Images of Callisto captured by passing spacecraft show bright white spots standing out against darker regions.
The Suomi NPP satellite is providing visible imagery and the Aqua satellite is providing temperature information on the tropical system.
This image from NASA’s Juno spacecraft captures several storms in Jupiter’s southern hemisphere. 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.
Scientists are using modern image processing techniques to create new views of Europa's surface. Callisto is tidally locked, so the same side always faces Jupiter. Director, NASA Planetary Science Division:
She was one of the followers of Artemis, or Diana for the Romans, who attracted Zeus (Jupiter). The Next Full Moon is the Strawberry Moon, Mead Moon, Honey Moon, Vat Purnima, Poson Poya, and the LRO Moon.
Vertical lift aircraft, including helicopters, is something NASA researchers have studied since the earliest days of flight. This may help provide water for astronauts exploring the Moon during the Artemis program. NASA's Perseverance Mars rover will carry the first samples of spacesuit material ever sent to the Red Planet. In Greek mythology, Callisto or Kallisto was a nymph, or the daughter of King Lycaon; the myth varies in such details.
Planetary scientist Geronimo Villanueva created the sunset simulations while building a tool for a possible mission to Uranus. A 3D model of Callisto, a moon of Jupiter.
Later, jus… Callisto is approximately the size of the planet Mercury, making it the third largest moon in the Solar System, after Ganymede and Titan.
Director, NASA Planetary Science Division: The books featured a soldier who is teleported to Callisto where he finds an ancient human civilization. Callisto is named for a woman turned into a bear by Zeus in Greek mythology. Callisto is tidally locked with Jupiter, which means that the same side of Callisto is always facing Jupiter.Callisto is about 1.8 times farther from Jupiter than Ganymede, 2.8 times farther than Europa and 4.5 times farther than Io, Jupiter’s closest large moon.
Callisto is one of the most ferocious soldiers in Layth's army. More recent research reveals that this ocean may be located deeper beneath the surface than previously thought, or may not exist at all.
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. Callisto’s circumference at its equator is about 9,410 miles (15,144 kilometers). It appears in several books and in the TV show “Cowboy Bebop,” Callisto has been terraformed and is home to mostly men.In the 1930s, writer Harl Vincent had Earth and Callisto at war in his novel “Callisto at War.”Isaac Asimov’s 1940 novel "The Callistan Menace” depicts Callisto as having an atmosphere of carbon dioxide and oxygen with lakes and vegetation.
She became pregnant and when this was eventually discovered, she was expelled from Artemis's group, after which a furious Hera (Juno), the wife of Zeus (Jupiter), transformed her into a bear.
