Carrying an ocean monitor,an asteroid-hunter and an android smartphone among the seven satellites on board,Indias trusted rocket,the Polar Satellite Launch Vehicle (PSLV)-C20,lifted off from Sriharikota in yet another successful mission.
The rocket took off from ISROs Satish Dhawan Space Centre on Monday evening,with President Pranab Mukherjee among those watching the launch from the space station. This was the 22nd successive successful launch for the PSLV.
For India,the main payload was the Indo-French satellite SARAL (Satellite with ARgos and ALtika). The satellite witnessed ISRO collaboration with the French space agency CNES. The 409-kg satellite will collect information on oceans and rains,help locate vessels and track migration of animals and birds.
Among the other satellites launched were NEOSSat a 74-kg Canadian surveillance satellite that will look out for asteroids over 50 million kilometres away. The search for asteroids is of interest as it comes after a meteorite recently crashed near Ural mountains in Russia. However,the makers of the satellite say that while it may be able to reduce the hazards of a similar impact,its basic design is to find bigger asteroids.
SAPPHIRE is another Canadian satellite which aims to survey objects orbiting earth,including active and old satellites. Denmarks AAUSAT3 will test the feasibility of tracking ships moving through the Arctic region.
Another payload that is of interest is the STRaND-1,from the UK,which is a unique yet simple contraption. It comprises a smartphone loaded with specific apps,stuck to a 30 cm x 10 cm cubesat. The Google Nexus phone has four apps that were selected based on a Facebook contest. One of the apps,Postcards from space,will take pictures of the Earth based on unique public demands. Another app,360,will provide photos on a map showing where they were taken.
As the name suggests,Scream in space app will allow a chosen few to test how they would sound in the space. Based on the creativity of the videos,those chosen will be able to speak via phone and their voice will be recorded through a microphone in orbit. The app,iTesa will record the magnetic field of the phone in orbit. This will test the possibility of making calls from outer space in the future. The last app,The STRaND Data,will monitor the satellite telemetry of the smartphone. The 3.5-kg STRaND satellite also has a 3D printed part an apparent first in space.
UniBRITE and BRITE are the other satellites onboard. These microsatellites,weighing 14 kg each,will study the brightest stars by observing their temperature variations.
