Multi-criteria comparison among several mitigation strategies for dangerous near Earth objects [PDF]
, 2009 In this paper a comparative assessment of the effectiveness of different deviation methods for Near Earth Objects is presented. Specifically, solar collector, nuclear interceptor, kinetic impactor, low-thrust propulsion, mass driver and gravity tug are ...

Asteroid resource map for near-Earth space [PDF]
, 2011 Most future concepts for the exploration and exploitation of space require a large initial mass in low Earth orbit. Delivering this required mass from the Earth’s surface increases cost due to the large energy input necessary to move mass out of the ...

Search for design solutions to prevent the Kessler effect [PDF]
E3S Web of Conferences, 2023 The article deals with the problems of near-earth space associated with the formation of objects called "space debris". The main sources of the appearance of "space debris" in near-earth orbits are highlighted.

Interception and deviation of near earth objects via solar collector strategy [PDF]
, 2008 A solution to the asteroid deviation problem via a low-thrust strategy is proposed. This formulation makes use of the proximal motion equations and a semi-analytical solution of the Gauss planetary equations.

NEOMOD: A New Orbital Distribution Model for Near-Earth Objects
The Astronomical Journal, 2023 Near-Earth Objects (NEOs) are a transient population of small bodies with orbits near or in the terrestrial planet region. They represent a mid-stage in the dynamical cycle of asteroids and comets, which starts with their removal from the respective ...

Accessibility of the resources of near Earth space using multi-impulse transfers [PDF]
, 2010 Most future concepts for exploration and exploitation of space require a large initial mass in low Earth orbit. Delivering this mass requires overcoming Earth's natural gravity well, which imposes a distinct obstacle to space-faring.

Optical Spectropolarimetry of Binary Asteroid Didymos–Dimorphos before and after the DART Impact
The Astrophysical Journal Letters, 2023 We have monitored the Didymos–Dimorphos binary asteroid in spectropolarimetric mode in the optical range before and after the DART impact. The ultimate goal was to obtain constraints on the characteristics of the ejected dust for modeling purposes ...

Evidence-based robust design of deflection actions for near Earth objects [PDF]
, 2012 This paper presents a novel approach to the robust design of deflection actions for Near Earth Objects (NEO). In particular, the case of deflection by means of Solar-pumped Laser ablation is studied here in detail. The basic idea behind Laser ablation is

Easily retrievable objects among the NEO population [PDF]
, 2013 Asteroids and comets are of strategic importance for science in an effort to understand the formation, evolution and composition of the Solar System. Near-Earth Objects (NEOs) are of particular interest because of their accessibility from Earth, but also
