Europa's gravity is approximately 13% of Earth's. The temperature on Europa varies from −160 °C at the equator, to −220 °C at either of its poles. [145] Europa's subsurface ocean is thought to be significantly [clarification needed] warmer however. It is hypothesized that because of radioactive and tidal heating (as mentioned in the ...
Hubley even set up its Scale Model Division for these products. These metal kits, issued in various scales, were more expensive than plastic models, and, when finished, were naturally quite heavy. Complexity in detail was often seen – with opening hoods, doors, moving phaeton panels, and detailed engines and chassis.
Europa Clipper is designed to follow up on evidence for a subsurface ocean underneath Europa's ice crust, found using the Galileo spacecraft which orbited Jupiter from 1995 to 2003. Plans to send a spacecraft to Europa were initially conceived with projects such as Europa Orbiter and Jupiter Icy Moons Orbiter , in which a spacecraft would be ...
The model car "kit" hobby began in the post World War II era with Ace and Berkeley wooden model cars. Revell pioneered the plastic model car in the late 1940s with their Maxwell kit, which was basically an unassembled version of a pull toy. Derek Brand, from England, pioneered the first real plastic kit, a 1932 Ford Roadster for Revell.

Major terrestrial gravity acquisitions by NIMA since 1990 include airborne gravity surveys over Greenland and parts of the Arctic and the Antarctic, surveyed by the Naval Research Lab (NRL) and cooperative gravity collection projects, several of which were undertaken with the University of Leeds. These collection efforts have improved the data ...

In geophysics and physical geodesy, a geopotential model is the theoretical analysis of measuring and calculating the effects of Earth's gravitational field (the geopotential). The Earth is not exactly spherical, mainly because of its rotation around the polar axis that makes its shape slightly oblate.
