India on Wednesday successfully placed into orbit its latest radar imaging earth observation satellite RISAT-2BR1 (s[py satellite) and nine foreign satellites from four countries using its PSLV rocket. In the process, India has touched the 319 foreign satellite launch mark since 1999.
India’s latest radar imaging earth observation satellite RISAT-2BR1, now up in the sky, will send sharp clarity images for surveillance, agriculture, forestry and disaster management. The satellite camera can look through clouds and take pictures. The Indian space agency officials said they would supply the required images for various agencies. It’s for the user agency to decide on how to use these images. One more such satellite RISAT-2BR2 will soon be launched by ISRO.

“I am extremely happy to declare that 50th PSLV rocket had injected the RISAT-2BR1 and nine customer satellites into precise orbit”, the ISRO Chairman said post launch. “Alongwith the 50th mission of PSLV rocket, the mission marks another milestone for ISRO. This is the 75th rocket launch from Sriharikota”, Sivan said in an official statement.
He further added, for the last 26 years, the PSLV rocket team was led by eminent persons like Srinivasan, former ISRO Chairman Madhavan Nair, R.V.Perumal, Ramakrishnan, and others. Sivan said the PSLV rocket has five variants now. The rocket that first had a capacity to carry 850 kg, now has a carrying capacity of 1.9 ton. He said the PSLV rocket has lofted a total of 52.7 ton to date and out of that 17% consists of customer satellites.

At about 3.25 p.m, the rocket Polar Satellite Launch Vehicle-QL (PSLV-QL) standing around 44.4 meters tall hurtled itself towards the skies ferrying 10 satellites. With the fierce orange flame at its tail brightening up the evening skies, the rocket slowly gathered speed and went up and up enthralling the people at the rocket port while the rocket’s engine noise like a rolling thunder adding to the thrill.
Guiding the rocket was the Vikram Processor-1601 designed by Vikram Sarabhai Space Centre (VSSC) and realized by the Chandigarh based Semi-Conductor Laboratory coming under Department of Space. The Vikram Processor is used for the rocket’s navigation, guidance and control and also for general processing applications.
It was the 50th flight of PSLV rocket and 75th rocket mission for the Sriharikota rocket port. Sharing the ride with RISAT-2BR1 were Anine foreign satellites from the USA (four multi-mission Lemur satellites, technology demonstration Tyvak-0129, earth imaging 1HOPSAT), Israel (remote sensing Duchifat-3), Italy (search and rescue Tyvak-0092) and Japan (QPS-SAR – a radar imaging earth observation satellite) for an unknown fee contracted by NewSpace India Ltd, the new commercial arm of ISRO.
Just over 16 minutes into its flight, the rocket first slung RISAT-2BR1 and a minute later the first of the nine customer satellites was ejected. The launch mission concluded in about 21 minutes when the last of the customer satellites were put into orbit. With this successful mission, ISRO has put into orbit 319 foreign satellites. The PSLV-QL is a four-stage/engine expendable rocket powered by solid and liquid fuels alternatively. The rocket has four strap-on booster motors to give additional thrust during the initial flight stages.
