  • The term Spaceguard loosely refers to a number of efforts to discover and study near-Earth objects (NEO). Arthur C. Clarke coined the term in his novel Rendezvous with Rama where SPACEGUARD was the name of an early warning system created following a catastrophic asteroid impact. This name was later adopted by a number of real life efforts to discover and study near-Earth objects.
  • The Infrared Astronomical Satellite (IRAS) was the first-ever space-based observatory to perform a survey of the entire sky at infrared wavelengths. Launched on January 25, 1983, its mission lasted ten months. The telescope was a joint project of the United States, the Netherlands, and the United Kingdom.
  • Observations for the Two Micron All-Sky Survey (2MASS) began in 1997 and were completed in 2001 at two telescopes located one each in the northern and southern hemispheres to ensure coverage of the entire sky. The most ambitious project to map the night sky to date, the final (post-processing) data release for 2MASS occurred in 2003. The whole sky was covered using photometric system of three infrared wavebands around 2 micrometres (m): J (1.25 m), H (1.65 m), and Ks (2.17 m).
  • The LIncoln Near-Earth Asteroid Research (LINEAR) project is a cooperative project between the United States Air Force, NASA, and MIT's Lincoln Laboratory for the systematic discovery and tracking of near-Earth asteroids. LINEAR was responsible for the majority of asteroid detections since 1998 until overtaken by the Catalina Sky Survey. As of December 31, 2007, LINEAR had detected 226,193 new objects of which at least 2019 were near-Earth asteroids and 236 were comets.
  • Near Earth Asteroid Tracking (NEAT) is a program run by NASA and Jet Propulsion Laboratory to discover near-Earth objects. The NEAT project began in December 1995 and ran until April 2007.
  • Catalina Sky Survey is a project to discover comets and asteroids, and to search for Near-Earth objects. More specifically, to search for potentially hazardous asteroids (PHAs), that may pose a threat of impact.
  • The Deep Ecliptic Survey (DES) is a project to find Kuiper belt objects (KBOs), using the facilities of the National Optical Astronomy Observatory (NOAO). The principal investigator is Bob Millis. Since 1998 through the end of 2003, the survey covered 550 square degrees with sensitivity of 22.5. I.e. , an estimated 50% of objects of this magnitude have been found.
  • The Asiago-DLR Asteroid Survey (ADAS) is a project to search for comets and asteroids, with special emphasis on near-Earth objects. It is a joint venture between the Department of Astronomy of the University of Padua (using the Schmidt telescope at Asiago-CimaEkar) and the DLR - Institute of Space Sensor Technology and Planetary Exploration at Berlin-Adlershof, Germany. DLR stands for Deutschen Zentrum für Luft- und Raumfahrt, the German Aerospace Center.
  • The OCA-DLR Asteroid Survey (ODAS) was a European scientific project to search for asteroids and comets. This project was the joint work of the Observatoire de la Côte d'Azur (OCA) in France and the Deutschen Zentrum für Luft- und Raumfahrt (DLR) in Germany. They operated in cooperation with a global effort regarding Near-Earth objects that was begun by the Working Group on Near-Earth Objects, a component of the International Astronomical Union.
  • BATTeRS (バッターズ) stands for Bisei Asteroid Tracking Telescope for Rapid Survey. It is a Japanese project to find asteroids. It is associated with the Japanese Spaceguard Association. Members include Takeshi Urata. The project has discovered numerous asteroids. It has also discovered the comet C/2001 W2 (BATTERS), later reclassified as periodic.

  • Hod HaSharon is a city in the Center District of Israel. Officially declared a city in 1990, Hod HaSharon was created from the union in 1964 of four neighboring villages: Magdiel, Ramatayim, Hadar, and Ramat Hadar. Its official land area is 19.239 square kilometers, and according to the Israel Central Bureau of Statistics (CBS), in December 2007 the city had a total population of 45,700.
  • Lars Valter Hörmander (born January 24, 1931 in Mjällby on the peninsula of Listerlandet in the county of Blekinge) is a Swedish mathematician who has been called "the foremost contributor to the modern theory of linear partial differential equations". He was awarded the Fields Medal in 1962, and the Wolf Prize in 1988. His Analysis of Linear Partial Differential Operators I–IV is considered a standard work on the subject of linear partial differential operators.
  • The SPAD S. VII was the first of a series of highly successful biplane fighter aircraft produced by Société Pour L'Aviation et ses Dérivés (SPAD) during the First World War. Like its successors, the S. VII was renowned as a sturdy and rugged aircraft with good climbing and diving characteristics. It was also a stable gun platform, although pilots used to the more manoeuvrable Nieuport fighters found it heavy on the controls.
