The random walk of cars and their collision probabilities with planetsIn this paper we investigate the fate of the Tesla over the next few million years. The roadster bears many similarities to Near Earth Asteroids (NEAs), which diffuse through the inner solar system chaotically through repeated close encounters with the terrestrial planets.Its first close encounter that may come within a lunar distance of the Earth will occur in 2091. Most of our 3 Myr realizations do not result in collisions with any solar system bodies, but we do find many cases where the Tesla impacts the terrestrial planets. Specifically, we numerically calculate a collision probability of ≈ 6% and ≈ 2.5% with the Earth and Venus over one million years, respectively. This leads us to estimate the dynamical half-life of the Tesla to be a few tens of Myr, similar to other NEAs.
SpaceX pourra travailler sur le "Human rated", avec la FH.

Du coup, la mission cislunaire qui était prévu pour deux touristes est aussi annulé. SpaceX se concentrera sur la Falcon 9 et la BFR pour le transport de passager.
Ah oui nous sommes bien sous la neige ! Et nous sommes aussi sous un froid arctique de -20°C depuis mercredi.
