Europe is anal sex video threeabout to send a spacecraft on an epic quest to study Jupiter's icy moons, a mission that won't begin in earnest for another eight years when it finally reaches its deep space destination.
The so-called "Juice" mission is intended to focus its research on Europa, Callisto, and particularly Ganymede, three large moons orbiting the gas giant planet a half-billion miles away. These moons have intrigued scientists for years, because they're thought to have liquid oceans trapped beneath icy shells.
Ganymede is the largest moon in the solar system and the only one known to have its own magnetic field, according to the European Space Agency (ESA). The mission will explore these worlds and investigate whether life could have ever flourished in this realm.

The ESA will attempt to launch Juice on an Ariane 5 rocket from its spaceport in French Guiana on the South American continent. It will be the space agency's last time using the rocket before it transitions to a new propulsion system. Liftoff is slated for 8:15 a.m. EST / 14:15 CEST Thursday April 13.

To understand the possibility of habitability, scientists need to explore the Jupiter system as a whole, said Olivier Witasse, a Juice mission scientist, during a recent ESA news conference. That means learning as much as they can about Jupiter's atmosphere and weather, strong rotating magnetic field, the volcanic moon Io, the other moons, and how they're all interconnected.

"Jupiter, it's really a miniaturized solar system," Witasse said. "It's the key to understand our own solar system — how it was formed, how it evolved with time."

Before reaching Jupiter, the spacecraft will make flybys of Earth and Venus to get enough energy to slingshot to the outer solar system, reaching Jupiter in 2031. If successful, it will be the first time in history a spacecraft has ever orbited a moon other than Earth's when it loops around Ganymede in 2034. NASA and the Japanese and Israeli space agencies have contributed scientific instruments for the mission.
Jupiter's "really a miniaturized solar system."
"Juice" is a wonky acronym for Jupiter Icy Moons Explorer, fitting for Ganymede's mythological namesake, who served as Jupiter's personal cupholder. The study seeks to answer several key questions: How do gas giants like Jupiter function; how did Jupiter's moons form; could there have been life on or around Jupiter in its past or even now; what are these oceanic moons like; and what makes Ganymede so different?

Karkoschka One of the biggest challenges for the mission was designing a spacecraft and instruments for the unusual environment around Jupiter. Particles from the volcanic moon Io are trapped by Jupiter's potent magnetic field, creating extreme radiation.
"We really had to put all the most sensitive equipment inside vaults, literally boxes lined with lead, that will stop most of the radiation from reaching the electronics," said Alessandro Atzei, the payload system engineer.
The launch will be streamed live on ESA Web TVand YouTube, from 7:45 — 10:05 a.m. EST. A post-launch briefing is planned to follow at 10:30 a.m. EST.
If the mission is delayed, the ESA team can try again once daily for the rest of April.
