PSLV-C53/DS-EO Mission

• ISRO undertakes PSLV-C53/DS-EO mission on June 30, 2022.
• PSLV-C53 is the second dedicated commercial mission of NewSpace India Limited (NSIL). It is designed to orbit DS-EO satellite along with two other co-passenger satellites from Singapore. This is the 55th mission of PSLV and 15th mission using PSLV-Core Alone variant.
• PSLV-C53 carries three satellites. DS-EO, a 365 kg and NeuSAR, a 155 kg satellite both belonging to Singapore. Third satellite is a 2.8 kg Scoob-1 of Nanyang Technological University (NTU), Singapore.
• DS-EO carries an Electro-Optic, multi-spectral payload that will provide full color images for land classification, and serving Humanitarian Assistance and Disaster Relief needs.
• NeuSAR is Singapore’s first small commercial satellite carrying a SAR payload, which is capable of providing images in day and night and under all weather conditions.
• SCOOB-I satellite is the first satellite in the Student Satellite Series (S3-I), a hands-on student training program from the Satellite Research Centre (SaRC) at Singapore’s NTU School of Electrical and Electronic Engineering.

PSLV-C52/EOS-04 Mission

• Launched on February 14, 2022 from Satish Dhawan Space Centre, SHAR, Sriharikota.
• The satellite EOS-04 is realised at U R Rao Satellite Centre, Bengaluru. It is a Radar Imaging Satellite designed to provide high quality images under all weather conditions for applications such as Agriculture, Forestry & Plantations, Soil Moisture & Hydrology and Flood mapping.
• The vehicle also placed two small satellites a student satellite (INSPIREsat-1) from Indian Institute of Space Science & Technology (IIST) in association with Laboratory of Atmospheric & Space Physics at University of Colorado, Boulder and a technology demonstrator satellite (INS-2TD) from ISRO, which is a precursor to India-Bhutan Joint Satellite (INS-2B).

GSLV-F10 / EOS-03

• GSLV-F10 launch took place on August 12, 2021 at 0543 Hrs IST as scheduled. Performance of first and second stages was normal.
• However, Cryogenic Upper Stage ignition did not happen due to technical anomaly. The mission couldn’t be accomplished as intended.

GSLV-F11 / GSAT-7A Mission

• GSLV-F11 is the 13th flight of India’s Geosynchronous Satellite Launch Vehicle (GSLV) and its 7th flight with indigenous Cryogenic Upper Stage (CUS).
• GSLV – F11 is ISRO’s fourth generation launch vehicle with three stages. The four liquid strap-ons and a solid rocket motor at the core form the first stage. The second stage of the vehicle is equipped with high thrust engine using liquid fuel. The Cryogenic Upper Stage forms the third and final stage of the vehicle.
• GSAT-7A with a lift-off mass of 2250 kg, is a geostationary satellite carrying communication transponders in Ku-band. The Satellite is built to provide communication capability to the users over the Indian region.

PSLV-C51/Amazonia-1

• PSLV-C51, the first dedicated launch for NSIL, successfully launches Amazonia-1 and 18 Co-passenger satellites from Sriharikota
• Amazonia-1 is the optical earth observation satellite of National Institute for Space Research (INPE). This satellite would further strengthen the existing structure by providing remote sensing data to users for monitoring deforestation in the Amazon region and analysis of diversified agriculture across the Brazilian territory.
• The 18 co-passenger satellites onboard PSLV-C51 includes four from IN-SPACe and fourteen from NSIL.
• Out of 4 satellites from IN-SPACe, three were UNITYsats designed and built as a joint development by Jeppiaar Institute of Technology, Sriperumbudur (JITsat), G.H.Raisoni College of Engineering, Nagpur (GHRCEsat) and Sri Shakti Institute of Engineering and Technology, Coimbatore (Sri Shakthi Sat) and one was Satish Dhawan Sat (SDSAT) from Space Kidz India.
• The fourteen satellites from NSIL carried were the commercial satellites from India (1) and USA (13).
