A multiple-vehicle strategy for near-Earth asteroid capture

چکیده
The use of asteroid resources could benefit future space missions. Instead lifting the necessary materials off Earth, they can be then sourced directly in space. Asteroid capture missions aim to bring asteroids closer where permanently accessed. This paper introduces a new strategy for missions, two spacecraft are used capturing near-Earth asteroids. These act together as ‘pitcher’ and ‘catcher’ spacecraft, pitcher hops from deflects them towards an orbit vicinity while catcher is stationed at Earth captures incoming novel two-spacecraft compared conventional one-spacecraft using three analyses; preliminary analysis coplanar circular orbits define problem, statistical fictional obtain large set data, real mission targets. A mass model developed compute retrieved per unit initial wet aiming retrieve multiple Results show that capable returning more often shorter duration.

Near-Earth Asteroid Search Programs
The discovery of the potentially hazardous near-Earth asteroid (NEA) component of the minor-planet population has been enhanced by better detecting and computing technology. A government mandate to quantify the terrestrial impact hazard and to detect 90% of all NEAs larger than 1 km can be realistically addressed. The characteristics, capabilities, and strategies of the major search programs il...
متن کاملNear Earth Asteroid Rendezvous: Mission Summary
On February 14, 2000, the Near Earth Asteroid Rendezvous spacecraft (NEAR Shoemaker) began the first orbital study of an asteroid, the near-Earth object 433 Eros. Almost a year later, on February 12, 2001, NEAR Shoemaker completed its mission by landing on the asteroid and acquiring data from its surface. NEAR Shoemaker’s intensive study has found an average density of 2.67 ± 0.03, almost unifo...
متن کاملThe hazard of near-Earth asteroid impacts on earth
Near-Earth asteroids (NEAs) have struck the Earth throughout its existence. During epochs when life was gaining a foothold f 4 Ga, the impact rate was thousands of times what it is today. Even during the Phanerozoic, the numbers of NEAs guarantee that there were other impacts, possibly larger than the Chicxulub event, which was responsible for the Cretaceous–Tertiary extinctions. Astronomers ha...
