@eurocelticyankee,
You don't need any busses ... especially to Alpha Centauri Bb. If you cannot imagine what a temperature of 1200 deg. C is, here are some references about the melting points of some metals:
- lead (Pb) - m.p. 328 deg C
- aluminium (Al) - 661 deg C
- copper (Cu) - m.p. 1085 deg C
With an iron sheep you will be at the edge of melting - 1538 deg C, and also with a titanium one - 1668 deg C.
You shoud go there with some ship of titanium or wanadium ceramics and insulated with solid layer of carbon penoplast. Your shoes have to be made of ... ceramics of silicon carbide, and you shoud line your lungs ... inside ... with fireproof flame-resistant neopren rubber.
In the summer in the tropic zone the air may be in the form of plasma (2500 deg C) ... but these are details.
BTW we travel in space and time all the time. We travel with the Earth around the Sun, we travel with the Solar System around Saggitarius, not to say that the Milky Way also travels in the Universe. Where are you going to travel. There is no place like home. We live on a tiny beautiful blue planet ... that we are about to destroy very soon with the CO2 bacchanalia.
