Description
Survey systems and telescopes are of paramount importance in the discovery of imminent impactors. State of the art and future additions to the network of telescopes will be portrait in this session.
Although Pan-STARRS is yet to discover an impacting asteroid, it has discovered a number of close-approaching asteroids. Several of these will be examined as case studies. Close approaching or impacting asteroids may have unremarkable digest scores as they approach Earth, which compounds the discovery problem, since they may not be listed on the Near-Earth Object Confirmation Page (NEOCP). The...
We present the communications architecture for the Asteroid Terrestrial-impact Last Alert System (ATLAS) and its suitability as a rapid responder in the global network of NEO detection and tracking. ATLAS is a worldwide system of wide-field telescopes dedicated to searching for hazardous asteroids, especially objects on close-approach or final trajectories. Since its construction in 2015,...
Over the past few years ESA's Planetary Defence Office has developed a network of small to medium sized telescopes with nearly-global coverage. This network is composed by ESA-owned and operated telescopes, but also by external facilities to which our team has access via dedicated contracts, scientific collaborations, institutional agreements or traditional proposals.
The goal of such network...
One of the major goals of ESA’s Planetary Defence Office is to discover Near-Earth Objects (NEOs) imminently before impact. Currently existing survey telescopes include ATLAS, Pan-STARRS and Catalina are contributing to a large number of new NEO discoveries each year, but to date, only five NEOs have been discovered before impact.
We present simulations carried out using a theoretical...
Catalina Sky Survey (CSS) has discovered three of the five imminent impactors detected to date. While the principal focus of CSS and other contemporary near-Earth object (NEO) surveys is to discover unknown larger members of the NEO population, CSS has demonstrated sensitivity to some smaller, nearby objects including imminent impactors during certain phases of their final approach. I will...
The Rubin Observatory is a new U.S. NSF/DOE-funded facility on Cerro Pachón, Chile, housing the 8.4m Simonyi Survey Telescope. The Observatory is in the final stage of construction, expected to achieve first light and enter commissioning in September 2023. Over a ten-year period Rubin will execute the Legacy Survey of Space and Time (LSST). Enabled by its 9.6 square degree field of view, a...
