The Near Earth Object Surveillance Satellite (NEOSSat) is a Canadian microsatellite
using a 15-cm aperture f/5.88 Maksutov
telescope
similar to that on the MOST
spacecraft, 3-axis stabilized with pointing stability of ~2 arcseconds in a ~100 second exposure. It will search for interior-to-Earth-orbit (IEO) asteroid
s including those sometimes called Apohele asteroid
s at between 45 and 55 degree solar elongation and +40 to -40 degrees ecliptic latitude.
After several postponements, launch is scheduled for December 2011.
Miniaturized satellite
Miniaturized satellites or small satellites are artificial satellites of unusually low weights and small sizes, usually under . While all such satellites can be referred to as small satellites, different classifications are used to categorize them based on mass .One reason for miniaturizing...

Maksutov telescope
The Maksutov is a catadioptric telescope design that combines a spherical mirror with a weakly negative meniscus lens in a design that takes advantage of all the surfaces being nearly "spherically symmetrical". The negative lens is usually full diameter and placed at the entrance pupil of the...

Telescope
A telescope is an instrument that aids in the observation of remote objects by collecting electromagnetic radiation . The first known practical telescopes were invented in the Netherlands at the beginning of the 1600s , using glass lenses...

Apohele asteroid
Apohele asteroids, or alternatively Interior-Earth Objects or Atira asteroids, are a subclass of Aten asteroids. They have not only their perihelion within Earth's orbit, but also their aphelion; that is, their entire orbit is within Earth's .The first suspected Apophele was , the first confirmed...
