The project Near Earth Object Surveillance Satellite ( N ear E arth O bject S urveillance Sat ellite ; German: Near-Earth Object Surveillance Satellite ) is a Canadian co-operation between the Canadian Space Agency CSA and the research organization DRDC of the Canadian Department of Defense , and the University of Calgary . The satellite manufacturer is Microsat Systems Canada . NEOSSat is Canada's second space telescope, after MOST , which has been in Earth orbit since 2003 and is still active.
begin
The start of NEOSSat was originally planned for spring 2010. After delays, it was launched on February 25, 2013 at 12:31 UTC with a PSLV launcher from launch pad 1 of the Indian Satish Dhawan Space Center on Sriharikota Island . With the same launch, the Canadian satellite Sapphire , the Indian satellite SARAL , the Austrian satellites UniBRITE and TUGSat 1 and the British STRaND 1 and the Danish AAUSAT were launched into space .
mission
The aim of the mission is to discover, track and catalog near-earth objects , satellites and space debris that are dangerously close to the earth. Furthermore, the new microsatellite technology is to be tested, which allows satellites and probes to be built smaller and therefore cheaper. The satellite operates in a Low Earth Orbit (LEO) at an altitude of around 650 km. Thus, the satellite will completely orbit the earth every 100 minutes. The planned duration of the mission is at least one year. The satellite is controlled from the CSA Satellite Control Center in Canada.
construction
NEOSSat is the first satellite to be built on the new multi-mission microsatellite bus from CSA. It has a weight of 74 kg and dimensions of 1 m × 0.4 m × 0.8 m with solar cells . The immensely expensive start-up costs can be drastically reduced as a result. The power consumption is approximately 35-50 W . The satellite is also equipped with gyroscopic systems, star sensors , sun sensors , magnetometers and an adapted F / 6 Maksutov telescope with a mirror diameter of 15 cm. The satellite costs approximately 12 million Canadian dollars.
