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 ...
The plastic track had two such lanes, and cars could change lanes with the flick of a switch on the controller. TCR sets came with "jam cars", a slow moving drone which both racers had to avoid crashing into. Like Matchbox's Powertrack, some cars featured lights.

The forces experienced by the rider are constantly changing ...
