On February 6th, 2018 SpaceX launched a Tesla Roadster on a Mars crossing orbit. We perform N-body simulations to determine the fate of the object over the next several million years, under the relevant perturbations acting on the orbit. The orbital evolution is initially dominated by close encounters with the Earth. The first close encounter with the Earth will occur in 2091. The repeated encounters lead to a random walk that eventually causes close encounters with other terrestrial planets…

Low-cost precursor of an interstellar mission

The solar photon pressure provides a viable source of thrust for spacecraft in the solar system. Theoretically it could also enable interstellar missions, but an extremely small mass per cross

Space situational awareness, for all its challenges, is relatively mature in LEO and GEO. In comparison, the situation beyond GEO is chaotic. No organization is charged with maintaining SSA for deep

Learning about rockets, in stages

A rocket must carry the fuel it expels in order to accelerate its structure and payload. The rocket equation relates the change in speed to the fuel mass expelled. To launch a spacecraft into Earth



Asteroids falling into the Sun

THE orbits of comets and near-Earth asteroids evolve chaotically, mainly in response to the gravitational influence of the planets. For comets, it is known that such perturbations can result in

Secular Resonances and the Dynamics of Mars-Crossing and Near-Earth Asteroids

Abstract We study by numerical integration the secular dynamical behavior of a sample of 32 Mars-crossing and near-Earth asteroids. We divide the planet-crossing asteroid population into two groups,

Existence of collisional trajectories of Mercury, Mars and Venus with the Earth

Numerical simulations of the evolution of the Solar System over 5 Gyr, including contributions from the Moon and general relativity find that one per cent of the solutions lead to a large increase in Mercury’s eccentricity—an increase large enough to allow collisions with Venus or the Sun.

Dating the Moon-forming impact event with asteroidal meteorites

It is inferred that the Moon formed 4.47 billion years ago, which is in agreement with previous estimates, by modeling their temporal evolution, and fitting the results to ancient impact heating signatures in stony meteorites.

Dynamical Lifetimes of Objects Injected into Asteroid Belt Resonances

Numerical simulations of particles placed in orbital resonances in the main asteroid belt show that the typical dynamical lifetimes of objects that could become near-Earth asteroids or meteorites are

The Exchange of Impact Ejecta Between Terrestrial Planets

Orbital histories of ejecta from the terrestrial planets were numerically integrated to study their transfer to Earth. The properties of the lunar and martian meteorites are consistent with a

Super-catastrophic disruption of asteroids at small perihelion distances

It is found that low-albedo asteroids are more likely to be destroyed farther from the Sun, which explains the apparent excess of high- albedo near-Earth objects and suggests thatLow-al Bedrock asteroids break up more easily as a result of thermal effects.

Simulation of general relativistic corrections in long term numerical integrations of planetary orbits

Long term numerical integrations of planetary orbits designed to study the stability of the Solar System over timescales comparable to i t s age have become very promising thanks to the availability
