Near-Earth asteroids (NEAs) in the 1-100 meter size range are estimated to be $\sim$1,000 times more numerous than the $\sim$15,000 currently-catalogued NEAs, most of which are in the 0.5-10 kilometer size range. Impacts from 10-100 meter size NEAs are not statistically life-threatening but may cause significant regional damage, while 1-10 meter size NEAs with low velocities relative to Earth are compelling targets for space missions. We describe the implementation and initial results of a real… 
Asteroids in the High cadence Transient Survey
We report on the serendipitous observations of Solar System objects imaged during the High cadence Transient Survey (HiTS) 2014 observation campaign. Data from this high cadence, wide field survey

ZStreak, a semi-real-time pipeline specialized in detecting small, fast-moving, near-Earth asteroids (NEAs), which is currently operating on the data from the newly commissioned Zwicky Transient Facility (ZTF) survey, features an improved machine-learning model that can cope with the 10× data rate increment between PTF and ZTF.

A visual technique, based on image processing will be presented as a possible future replacement for the current technique used now in NEARBY pipeline, the astronomical solution based on computation in the celestial reference system.
Euclid: Identification of asteroid streaks in simulated images using StreakDet software
Context. The ESA Euclid space telescope could observe up to 150 000 asteroids as a side product of its primary cosmological mission. Asteroids appear as trailed sources, that is streaks, in the
The Zwicky Transient Facility: Science Objectives
The Zwicky Transient Facility (ZTF), a public–private enterprise, is a new time-domain survey employing a dedicated camera on the Palomar 48-inch Schmidt telescope with a 47 deg^2 field of view and
Asteroid Retrieval Technology Development From the Asteroid Return Mission Study
The Keck Institute for Space Studies (KISS) workshops on the Asteroid Return Mission concept explored and established the feasibility of capturing and returning an entire near-Earth asteroid (NEA) to
Exploration of a Visual Technique in Asteroids Detection Process
A visual technique based on image processing under different shades will be investigated as an alternative to the currently used astronomical technique which is based on computation in the celestial reference system.
This paper proposed a method based on computer vision techniques to detect the moving objects in NEOSSat images autonomously and also estimate their path, and designed a graphical user interface for the software, encouraging public usage.
The Zwicky Transient Facility: System Overview, Performance, and First Results
The Zwicky Transient Facility is a new optical time-domain survey that uses the Palomar 48 inch Schmidt telescope, and the ZTF data system at the Infrared Processing and Analysis Center provides near-real-time reduction to identify moving and varying objects.
Optimal and Efficient Streak Detection in Astronomical Images
This work applies the fast Radon transform to detect streaks that are barely visible to the eye, out of hundreds of images, without a-priori knowledge of the streaks' positions or angles.


With the NEOWISE portion of the Wide-field Infrared Survey Explorer (WISE) project, we have carried out a highly uniform survey of the near-Earth object (NEO) population at thermal infrared
Asteroid Discovery and Characterization with the Large Synoptic Survey Telescope
Tests with the prototype MOPS software indicate that linking detections will be possible at LSST depths with the working model for the survey strategy, but evaluation of MOPS and improvements in the surveying strategy will continue.
Near miss of the Earth by a small asteroid
THE 0.91-m Spacewatch Telescope, on Kitt Peak in Arizona, is being used to search for new Earth-approaching asteroids. On the night of 18 January 1991 a streaked image extending over more than 161
The Near-Earth Asteroid Tracking (NEAT) Program: An Automated System for Telescope Control, Wide-Field Imaging, and Object Detection
The Near-Earth Asteroid Tracking (NEAT) system operates autonomously at the Maui Space Surveillance Site on the summit of the extinct Haleakala Volcano Crater, Hawaii. The program began in 1995
Initial asteroid detection results using the Space Surveillance Telescope
The Lincoln Near Earth Asteroid Research (LINEAR) program, funded by the National Aeronautics and Space Administration (NASA), conducted asteroid search from 1998 to 2013 using two 1m optical
The flux of small near-Earth objects colliding with the Earth
Satellite records of bolide detonations in the atmosphere over the past 8.5 years are reported and it is found that the flux of objects in the 1–10-m size range has the same power-law distribution as bodies with diameters >50 m.
Automated CCD Scanning for near Earth Asteroids
The Spacewatch group at the University of Arizona’s Lunar and Planetary Laboratory was probably the first (1984) to implement CCD-scanning in a major astronomical program. In the past three years,
