EXPLORENEOs. I. DESCRIPTION AND FIRST RESULTS FROM THE WARMSPITZERNEAR-EARTH OBJECT SURVEY
We have begun the ExploreNEOs project in which we observe some 700 Near-Earth Objects (NEOs) at 3.6 and 4.5 μm with the Spitzer Space Telescope in its Warm Spitzer mode.

Taxonomy of Subkilometer Near-Earth Objects from Multiwavelength Photometry with RATIR [PDF]
We present results from observations of 238 near-Earth objects (NEOs) obtained with the RATIR instrument on the 1.5 m robotic telescope at San Pedro Martir’s National Observatory in Mexico, in the frame of our multiobservatory, multifilter campaign.

Structurally topological algorithm for star recognition and near-Earth space’ object detection [PDF]
When solving a variety of celestial navigation tasks there is a problem of determining parameters of spacecraft motion and onboard primary payload orientation based on the coordinates of registered star images.

Algorithms for Moving Object Detection: YSTAR-NEOPAT Survey Program [PDF]
We developed and compared two automatic algorithms for moving object detections in the YSTAR-NEOPAT sky survey program. One method, called starlist comparison method, is to identify moving object candidates by comparing the photometry data tables from ...

The NEO Surveyor Near-Earth Asteroid Known Object Model
The known near-Earth object (NEO) population consists of over 32,000 objects, with a yearly discovery rate of over 3000 NEOs per year. An essential component of the next generation of NEO surveys is an understanding of the population of known objects ...

Automated Streak Detection for High Velocity Objects: Test with YSTAR-NEOPAT Images [PDF]
We developed an algorithm to efficiently detect streaks in survey images and made a performance test with YSTAR-NEOPAT images obtained by the 0.5m telescope stationed in South Africa. Fast moving objects whose apparent speeds exceed 10 arcsec/min are the

Visible Spectroscopy from the Mission Accessible Near-Earth Object Survey (MANOS): Taxonomic Dependence on Asteroid Size [PDF]
The Mission Accessible Near-Earth Object Survey (MANOS) aims to observe and characterize small (mean absolute magnitude H ∼ 25 mag) Near-Earth Objects (NEOs) that are accessible by spacecraft (mean Δv ∼ 5.7 km s−1) and that make close approaches with the
