Near-Earth Object Surveyor Overview
IEEE Aerospace Conference, 2022The Near-Earth Object (NEO) Surveyor is designed to detect, categorize and characterize Near-Earth Objects (NEOs) using infrared imaging. The project was approved to enter the preliminary design phase (Phase B) in FY21 after an extended Concept ...

Distribution of the near-earth objects
Solar System Research, 2011This paper analyzes the distribution of the orbits of near-Earth minor bodies from the data on more than 7500 objects. The distribution of large near-Earth objects (NEOs) with absolute magnitudes of H < 18 is generally consistent with the earlier predictions (Bottke et al., 2002; Stuart, 2003), although we have revealed a previously undetected maximum ...

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 ...

Asteroids and comets probably contributed significantly to the delivery of water and organic materials to the early Earth necessary for the development of life. However, later impacts of near-Earth objects almost certainly played a role in mass extinctions and evolution.

Autonomous on-board Near Earth Object detection
International Conference on Artificial Intelligence and Pattern Recognition, 2015Most large asteroid population discovery has been accomplished to date by Earth-based telescopes. It is speculated that most of the smaller Near Earth Objects (NEOs) that are less than 100 meters in diameter, whose impact can create substantial city-size

Physical characterization of the near-Earth object population
The European Physical Journal Plus, 2017The Near-Earth Object (NEO) population, being the remnants of the building blocks that originally formed our solar system, allows us to understand the initial conditions that were present in the protosolar nebula. Its investigation can provide crucial information on the origin and early evolution of the solar system, and shed light on the delivery of ...

Defending planet Earth : near-Earth-object surveys and hazard mitigation strategies
, 2010The United States spends approximately $4 million each year searching for near-Earth objects (NEOs). The objective is to detect those that may collide with Earth.

The population of near-Earth objects discovered by Spacewatch [PDF]
Earth, Moon, and Planets, 1996 In the past three years the Spacewatch program at the University of Arizona’s Lunar and Planetary Laboratory has discovered ~45% of the new Earth Approaching asteroids and found evidence for an unheralded population of small (~10m) objects in the inner solar system.

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 debiased compositional distribution of Near-Earth Objects
2022<p>We report 491 new near-infrared spectroscopic measurements of 420 Near-Earth Objects (NEOs) collected on NASA&#8217;s IRTF in the context of MITHNEOS (PI: DeMeo). The measurements were combined with previously published data (Binzel et al.
