ISRO launches Indo-us unique earth observing mission NISAR into space
BENGALURU: The Indian Space Research Organisation (ISRO) on Wednesday successfully launched the NASA-ISRO Synthetic Aperture Radar (NISAR) at 5.40 pm from Satish Dhawan Space Centre (SDSC), Sriharikota High Altitude Range (SHAR), marking the 102nd launch from here. This is the first collaborative mission between ISRO and NASA – costing $1.5 billion and with a mission life of five years – in which the unique satellite's dual-band Synthetic Aperture Radar (SAR) will employ advanced, novel SweepSAR technique, to provide high-resolution and large swath imagery. The 2,393-kg NISAR satellite will image the global land and ice-covered surfaces, including islands, sea ice and selected oceans every 12 days. The lift-off of the 51.7-metre-tall GSLV F-16, carrying the 2,393-kg NISAR satellite, took place at the end of a 27.30-hour countdown from SDSC-SHAR's second launch. Precisely 19 minutes after lift-off, ISRO's launcher GSLV F-16 injected NISAR into a Sun Synchronous Polar Orbit (SSPO) at an orbit altitude of 747 km – the first time that ISRO's GSLV (Geostationary Satellite Launch Vehicle) has placed a satellite in a sun-synchronous orbit, as all earlier GSLV launches had placed satellites in Geosynchronous Transfer Orbit (GTO). ISRO Chairman and Secretary, Department of Space, V Narayanan, said after the successful launch and satellite's orbital insertion, 'All the vehicle system performances were quite normal as expected and as predicted. Today, we achieved the intended orbit. Actually, we have got an orbit with a dispersion (deviation from desired orbit) of less than 3 km, as against the permissible level of 20 km... all parameters are as expected.' He added that GSLV F-16's cryogenic upper stage corrections and a host of mission simulations were carried out very systematically and meticulously. Chaitra Rao, Project Spacecraft Director, NISAR, said that as per schedule, NISAR's solar panels were deployed and the satellite was appropriately titled. The first 90 days of the mission will be dedicated to commissioning, or In-Orbit Checkout (IOC), to prepare NISAR for science operations. Commissioning is divided into sub-phases of initial checks and calibrations of mainframe elements followed by NASA's Jet Propulsion Laboratory (JPL) engineering payload and instrument checkout.

Indo-US space collab takes flight with NISAR success
Sriharikota: India and the US on Wednesday marked their maiden space collaboration with the successful flight of a GSLV rocket that placed an earth observation satellite, jointly developed by the two space agencies, in a precise orbit. ISRO's GSLV F-16 injected NISAR — NASA-ISRO Synthetic Aperture Radar satellite, into the intended Sun Synchronous Polar Orbit (SSPO), after a flight of about 19 minutes and around 745 km. GSLV 'successfully injected NISAR in designated orbit,' ISRO said. Wednesday's accomplishment follows the unsuccessful PSLV-C61/EOS-09 Mission on May 18, where a faulty PSLV of ISRO failed to deliver the earth observation satellite in the desired orbit. After successfully launching similar satellites–Resourcesat and RISAT series which were operationally focused on India, ISRO through the NISAR mission is embarking on a journey to study planet Earth. At the end of the 27.30-hour countdown, the 51.7-metre tall launch vehicle carrying the 2,393 kg satellite majestically lifted-off from the second launch pad at the Satish Dhawan Space Centre, here, situated about 135 km east of Chennai at a prefixed time of 5.40 pm on Wednesday. Post the separation from the rocket, the scientists would embark on commissioning the satellite which would take 'several days' to position it and meet the mission objectives. According to ISRO, the S-band Radar system, data handling and high-speed downlink system, the spacecraft and the launch system are developed by the national space agency. The L-band Radar system, high speed downlink system, the Solid State Recorder, GPS receiver, the 9m Boom hoisting the 12m reflector are delivered by US-based National Aeronautics Space Administration (NASA). 'Further, ISRO is responsible for the satellite commanding and operations. NASA will provide the orbit maneuver plan and RADAR operations plan. NISAR mission will be aided with ground station support of both ISRO and NASA for downloading of the acquired images, which after the necessary processing will be disseminated to the user community,' it said. The data acquired through S-band and L-bandR from a single platform will help the scientists to understand the changes happening to Earth. According to ISRO, the NISAR mission's primary objectives are to study land and ice deformation, land ecosystems, and oceanic regions in areas of common interest to the US and Indian scientific communities. The mission would help in measuring the woody biomass, track changes in the extent of active crops, understand the changes in wetlands extent among others. The mission life of NISAR is 5 year. NASA said the data from NISAR mission would provide critical insights to help governments and decision-makers plan for natural and human-caused hazards. NISAR can help with hazard-monitoring efforts and potentially give decision- makers more time to prepare for a possible disaster. The RADAR satellite would provide a 3D view of the Earth's land and ice and through its ability to see through clouds and light rain, day and night, the satellite would enable data users to continuously monitor earthquake and landslide prone areas and determine how quickly glaciers and ice sheets are changing. The data collected from the satellite would also offer an 'unprecedented coverage of Antarctica, an information that would help with studying how the continent's ice sheet changes over time. Significantly, NISAR is the most advanced radar system ever launched by NASA or ISRO and it would generate more data on a daily basis than any previous Earth satellites launched by them. The NISAR mission would help the two space agencies to monitor ecosystems around the world and the L band penetrates deep into forest canopies, providing insights into forest structure, while the S-band radar is monitoring crops. The NISAR data would help researchers assess how forests, wetlands, agricultural areas change over time.

Hyderabad-based ATL delivers nine critical sub-systems for NISAR satellite
City-based Ananth Technologies (ATL) announced its proud moment to have played a part in the successful GSLV F-16 launch carrying the NASA-ISRO Synthetic Aperture Radar (NISAR) satellite, which includes critical avionic packages like assembly, integration, and testing for the mission. ATL chairman and managing director Subba Rao Pavuluri said that the company had delivered 14 critical sub-systems such as power modules, telemetry transmitters, stage control electronic units, besides executing the complete electrical integration of the launch vehicle. For NISAR satellite, it has delivered nine critical sub-systems made at its world-class satellite manufacturing facilities. 'ISRO's success inspires all of us in the space eco-system to continue striving for excellence and innovation,' he said, while congratulating the organisation. ATL has been a trusted partner of ISRO for over three decades, contributing in satellite systems, launch vehicle components, and mission-critical technologies. Headquartered in Hyderabad, ATL operates advanced facilities in Thiruvananthapuram for the fabrication, assembly, and testing of launch vehicle sub-systems and satellites. It has contributed to the success of 105 satellites and 85 launch vehicles for India's space programmes, he said in a press release on Wednesday.
