NEOSSat

 2013-009D


Near Earth Object Surveillance Satellite, CSA/DRDC using CSA/Dynacon MMMB multimission microsat bus to survey asteroids down to V=20.

The NESS mission surveys NEOs at solar elongation 45 to 55 deg and ecliptic latitude |b|<40 deg.

The HEOSS mission surveys resident space objects (RSOs) to 13.5 mag at altitude above 15000 km.

50 kg, 15 cm telescope; derived from MOST. Size 1.8 x 0.4 x0.8m.

The spacecraft software was delivered behind schedule; it was only in 2014 Jun that the software was improved enough to take good quality images, and tracking was still unable to meet mission needs.
