Sriharikota (Andhra Pradesh): The Indian Space Research Organization (ISRO) successfully launched two Singapore satellites on Saturday afternoon at 2:19 pm with PSLV-C55 rocket. TeLEOS-2 and LUMELITE-4 were placed in low Earth orbit by the mission launched from the Satish Dhawan Space Center in Sriharikota, Andhra Pradesh.
ISRO's experimental platform POEM was also sent in this mission. POEM will do some testing in the vacuum of space. This was the 57th flight of PSLV.
This is a dedicated commercial mission through NSIL with TeLEOS-2 as primary satellite and Lumelite-4 as a co-passenger satellite. The satellites weigh about 741 kg and 16 kg, respectively. Both belong to Singapore. They are intended to be launched into an Eastward low inclination orbit.
The TeLEOS-2 satellite is developed under a partnership between DSTA (representing the Government of Singapore) and ST Engineering. Once deployed and operational, it will be used to support the satellite imagery requirements of various agencies within the Government of Singapore.
TeLEOS-2 carries a Synthetic Aperture Radar (SAR) payload. TeLEOS-2 will be able to provide all-weather day and night coverage, and capable of imaging at 1m full-polarimetric resolution.
Four stage rocket
The full form of POEM is PSLV Orbital Experimental Module. PSLV is a four stage rocket. Its three stages fall into the ocean. The last i.e. the fourth stage, which is also called PS4, after the satellite is delivered to its orbit, the garbage of space remains. Now POEM will be used to experiment on top of this. This is being done for the fourth time.
