Earth's Temporarily-Captured Natural Satellites { The First Step on the Ladder to Asteroid Resources
نویسندگان
چکیده
The Earth is surrounded by a cloud of small asteroids that have been temporarily captured from the near-Earth-object population into Earth-centric orbits. These temporarily-captured Earth orbiters (TCOs) form a natural rst target for any project that aims to take advantage of material resources available in asteroids. We review our current knowledge of the characteristics of the TCO population and their detectability. We also discuss the feasibility of a space mission to a TCO in terms of possible transfer orbits and highlight some of the remaining challenges.

Rendezvous Missions to Temporarily-Captured Near Earth Asteroids
Missions to rendezvous with or capture an asteroid present significant interest both from a geophysical and safety point of view. They are key to the understanding of our solar system and are stepping stones for interplanetary human flight. In this paper, we focus on a rendezvous mission with 2006 RH120, an asteroid classified as a Temporarily Captured Orbiter (TCO). TCOs form a new population ...
متن کاملGravitational Capture of Asteroids by Gas Drag
Several irregular satellites of the giant planets were found in the last years. Their orbital configuration suggests that these satellites were asteroids captured by the planets. The restricted three-body problem can explain the dynamics of the capture, but the capture is temporary. It is necessary some kind of dissipative effect to turn the temporary capture into a permanent one. In this work ...
متن کاملAsteroid Capture Using a Binary Exchange Mechanism
A new method of capturing an asteroid in an orbit around the Earth is proposed, inspired by the theory that the irregular satellites of Jupiter and Neptune may have at one time been members of a binary asteroid. After a close approach with the planet, the binary asteroid was disrupted, and one member was captured into a permanent orbit. A parametric study was conducted by simulating binary-Eart...

متن کاملGenetic Variability and Karyotype Analysis for 13 Accessions of Lolium multiflorum
Genetic variations were studied for 13 accessions of Lolium multiflorum using cytogenetical traits. Karyotype was prepared for 5 metaphases cells of each accession and the traits of total length (TL), long arm (LA), short arm (SA), arm ratio (AR) and centromer index (CI) were determined by micromeasure software. Six accessions were diploid and seven accessions were tetraploid, the basic chromos...
