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 ...
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 ...
[1] [2] [3] The stage was intended to be injected into a permanent heliocentric orbit in November 1969, but is now believed instead to have gone into an unstable high Earth orbit which left Earth's proximity in 1971 and again in June 2003, with an approximately 40-year cycle between heliocentric and geocentric orbit.
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 first sets consisted of up to 4 Formula 5000 cars. The track (which stayed the ...
As the car approaches a loop, the direction of a passenger's inertial velocity points straight ahead at the same angle as the track leading up to the loop. As the car enters the loop, the track guides the car up, moving the passenger up as well. This change in direction creates a feeling of extra gravity as the passenger is pushed down into the ...

The track connectors are square and slot into place unlike the ring shaped Classic track ones. Converter pieces are available to link to Classic track. Scalextric Digital: Released in 2004, Scalextric Digital is compatible with Sport. It allows up to 6 cars on a 2 lane track at one time, with each car fully controllable.
Alongside the track, model planets and their moons are located at the correct scaled distances from the Sun. Information plaques are located at each planet. The walk finishes at Pluto, although Pluto is now defined as a dwarf planet, rather than a planet. On the 1km scale model, the relative size of the Earth should be about the size of a ...
