The high-gain antenna operates on X-band frequencies of 7.2 and 8.4 gigahertz, and a Ka-band frequency of 32 gigahertz (12 times that of a typical cell phone).The antennas will be used to research gravity and radio science, allowing researchers to learn more about Europa's gravity [88] It was designed and constructed by a team led by Matt Bray ...
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 ...
Up through the 1950s, the emphasis was on children's toys, though some of these so-called toys could be fairly sophisticated, like the eleven and a half inch long Indian 'crash car' cast iron motorcycle complete with parts and accessories, or a fairly complex tow truck. Hubley made simple diecast metal toys all the way through the 1970s.
Apparently, the terms of the deal were that Carr would construct a full-scale, 45-foot (14 m) mockup of his saucer, OTC X-1, to be converted into a ride for the park. Carr relocated to Oklahoma City, provided the park with a dummy OTC X-1, and claimed to be readying a 6-foot (1.8 m) "prototype" of his saucer for a demonstration flight at the ...
It is a generalisation of the vector form, which becomes particularly useful if more than two objects are involved (such as a rocket between the Earth and the Moon). For two objects (e.g. object 2 is a rocket, object 1 the Earth), we simply write r instead of r 12 and m instead of m 2 and define the gravitational field g(r) as:

The Europa S has a dry weight of just 995 kg (2,194 lb) achieved by an extruded and bonded aluminium chassis with composite body panels and front crash structure.. The Europa S is a derivative of the Lotus Elise and Exige to the extent that the cars have variations of the same bonded aluminium chassis but the Europa bears a separate Lotus model designation (Type 121) due, in part, to its ...
