Near Earth object mitigation studies
2016 IEEE Aerospace Conference, 2016Early detection of an object on a collision course with Earth, leading to well-considered and effective measures to mitigate its hazards, is not always possible due to a number of extenuating factors. NASA and the Department of Energy (DOE)'s National Nuclear Security Administration (NNSA) have partnered to develop a full systems framework for ...

Impacting small Near Earth Objects
Advances in Space Research, 2008Abstract The design of a low-cost spacecraft to impact on a small, faint Near Earth Object (NEO), poses major challenges. This paper focuses on the terminal phase of such impact mission, analyzing the capability of autonomous Guidance, Navigation and Control (GNC) systems to compensate the deviations in the impact point to achieve a successful ...

The chances of a random piece of rock striking Earth still exists, but probably to a much reduced level of threat. During the early years in the creation of our Solar System, there was plenty of debris that had yet to settle into some form and order, with constant collisions of large bodies before any structure was imposed.

The Near-Earth Object Population
Icarus, 2000We examine the dynamics of a sample of 117 near-Earth objects (NEOs) over a time scale of 60 Myr. We find that while 10–20% end their lifetimes by striking a terrestrial planet (usually Venus or Earth), more than half end their lives in a Sun-grazing state, and about 15% are ejected from the Solar System.

INEO—Imaging of near-Earth objects
Acta Astronautica, 1994Abstract INEO is a program of four explorer flyby missions for imaging near-Earth objects by means of small spin stabilized spacecrafts. A low-cost approach is achieved by using existing hardware and available scientific instrumentation. For the first mission the payload consists of the flight space model of the Halley multicolour camera and three ...
