Given that Europa's surface is icy, and subsequently very cold; as solar ultraviolet radiation and charged particles (ions and electrons) from the Jovian magnetospheric environment collide with Europa's surface, water vapor is created and instantaneously separated into oxygen and hydrogen constituents.
The Radar for Europa Assessment and Sounding: Ocean to Near-surface (REASON) [99] [100] is a dual-frequency ice penetrating radar (9 and 60 MHz) instrument that is designed to sound Europa's ice crust from the near-surface to the ocean, revealing the hidden structure of Europa's ice shell and potential water pockets within.
The Radar for Europa Assessment and Sounding: Ocean to Near-surface (REASON) is a multi-frequency, multi-channel ice penetrating radar system that will be flown on board the Europa Clipper mission to Jupiter's moon Europa. REASON investigation will provide the first direct measurements of Europa's ice shell surface character and subsurface ...
A SpaceX Falcon Heavy rocket carrying NASA's Europa Clipper space probe launches from Kennedy Space Center on Oct. 14, 2024, on a mission to orbit Jupiter and study its icy moon, Europa, for signs ...
Its icy shell is believed to be 10-15 miles (15-25 km) thick, sitting atop an ocean 40-100 miles (60-150 km) deep. ... and hunting for plumes of water vapor that may be venting from Europa's icy ...
The images provide new insights into the chemical composition of two of Jupiter’s moons.
Electromagnetic waves between 10 −2 to 1 hertz could reveal localized mass flow of ions arising from plumes and the atmosphere; that is, localized transient currents indicate plume activity. [2] In general, ICEMAG data would have combined synergistically with other data sets to improve knowledge of interior properties and exosphere activity.
Europa (Jupiter II), the second of the four Galilean moons, is the second closest to Jupiter and the smallest at 3121.6 kilometers in diameter, which is slightly smaller than Earth's Moon. The name comes from a mythical Phoenician noblewoman, Europa , who was courted by Zeus and became the queen of Crete , though the name did not become widely ...
