The UAO – DLR Asteroid Survey (UDAS), also known as the Uppsala-DLR Asteroid Survey, is a dedicated programme to search for and follow up asteroids and comets, with special emphasis on near-Earth objects (NEOs) in co-operation and support of global efforts in NEO-research, initiated by the Working Group on Near-Earth Objects (WGNEO) of the International Astronomical Union (IAU), and the Spaceguard Foundation. It is a kind of follow-on programme to ODAS, which had to close due to lack of further financial support. It should also not be confused with the Uppsala-DLR Trojan Survey (UDTS), which was conducted a few years before UDAS was launched.
UDAS began regular observations in September 1999, with some test runs during 1998. Discoveries of NEOs are reported to the Minor Planet Center.
UAO stands for Uppsala Astronomical Observatory, Uppsala, Sweden. DLR stands for the Deutschen Zentrum für Luft- und Raumfahrt, the German Aerospace Center.
Famous quotes containing the word survey:
“In a famous Middletown study of Muncie, Indiana, in 1924, mothers were asked to rank the qualities they most desire in their children. At the top of the list were conformity and strict obedience. More than fifty years later, when the Middletown survey was replicated, mothers placed autonomy and independence first. The healthiest parenting probably promotes a balance of these qualities in children.”
—Richard Louv (20th century)
