Scientists working on one of the biggest collaborative projects undertaken by ISRO and NASA will take the project a step ahead today by kicking off the radar flight testing of NISAR (NASA-ISRO Synthetic Aperture Radar). A special aircraft landed at the city airport on Tuesday to carry the radars developed at the Space Application Centre’s (SAC) Ahmedabad facility for initial testing.
It should be noted that the SAC developed radar will be tested in Ahmedabad’s sky for three months. As per sources, the radar developed by SAC will be fixed on a Beechcraft Super King B 200 — owned by ISRO — for the first flight primarily to ‘understand weather and geographical conditions’ to continue testing further. NISAR mission is a dual frequency (L & S Band) Radar Imaging Satellite. Confirming the development, SAC Director Tapan Misra said, “We will test the radar by taking images from about 8km above sea level; the same area will be further studied by scientists from ground level to understand the radar’s accuracy level.
“The flying is essentially to understand how the radar sees the crops,” said Misra. The data collection and observation will also scientists time to analyse and simulate data from the radar. The mission is schedule for a launch in 2020.
India's space agency, ISRO, and NASA of the US are working on the development of advanced space-based sensors and radar systems that can help sharpen earth observation applications in the future, according to Tapan Misra, Director of the Ahmedabad-based Satellite Application Centre (SAC).One of the focus areas of the joint venture called NISAR (NASA-ISRO Synthetic Aperture Radar) is making sensors in the L&S band. These can help in observations such as deformations in the land surface, details of the coastline and depths of the ocean, to aiding in disaster response.Misra made these observations while delivering a lecture organised by the Aeronautical Society of India (ASI) and the Sensors Research Society of India here on Friday. The NISAR project agreement signed between the two agencies aims to launch an earth monitoring satellite by 2021.
The SAC will take the lead in the development of C-band radar imaging as well as in microwave and optical sensors, which have a big role to play in the future. The Indian Space Research Organisation is planning missions to gear itself to meet the growing demands for observational studies with multiple applications.In the quest to connect the benefit of space-based observations to the advantage of the common man, SAC has conceived and launched a spectrum of optical and microwave payloads. In the last two decades, the optical observation capability has improved from 35 m to 60 cm. Sensor technology has changed from electrical transducers to integrated chips & is visible to microwaves," he said.At present there are 13 operational Earth Observation (EO) satellites. SAC has built specific air-borne electro-optical sensors to meet the exclusive requirements of high resolution and hyper-spectral imaging from an aerial platform as well, Misra added.
Isro sources claim that the NISAR satellite will be launched, hopefully, by 2020-21. Misra said that joint testing of NISAR’s two radar systems — the S-Band developed by Isro and the L-band radar developed by the US — will be conducted soon and the two technologies will be integrated.
On a billion dollar Isro-Nasa joint project to co-develop an earth observation satellite with synthetic aperture radars (NISAR mission) whose launch is expected next year, Bolden, a former astronaut, said, "The satellite will be the first radar imaging satellite to use dual frequencies. Nasa will provide L-band synthetic aperture radar while Isro will provide an S-band synthetic aperture radar. India is providing a particular sensor and a wavelength which we (US) don't have. Therefore the joint collaboration."Once launched, the NISAR satellite will help observe and take measurements of some of the planet's most complex processes, including ecosystem disturbances, ice-sheet collapse and natural hazards.

Mysuru: Dr. Abhishek A. Pathak, Assistant Professor, Department of Civil Engineering, The National Institute of Engineering (NIE), Mysuru, has been selected for the prestigious ‘SERB International Research Experience’ Fellowship to work at Hydrological Science Laboratory, Goddard Space Flight Centre, NASA, USA.
Dr. Pathak will work on synergetic assimilation of soil moisture and hydrometeorological variables to develop a comprehensive combined drought monitoring framework for India. The proposed research will also play a vital role in providing a base for various studies, which will be carried out with the up-coming NASA-ISRO SAR (NISAR) mission scheduled to be launched in 2023.
Payload integration of NASA-Isro Synthetic Aperture Radar mission completed in USBENGALURU: The payload integration of the NASA-Isro Synthetic Aperture Radar mission (NISAR) has been completed in the US and the same is expected to be shipped to India later this year for integration with the satellite and eventually the launch vehicle, senior NASA officials said here on Wednesday.
Thomas Zurbuchen, associate administrator, NASA science mission directorate on future Space exploration, terming it an extremely complex mission, said progress had been made on NISAR after Covid-induced delays.“We’ve already met Isro scientific secretary and will be meeting the chairman later today (Wednesday) for discussions,” Zurbuchen said at a public event at the Indian Institute of Science (IISc). The main purpose of the NASA team’s visit is to deliberate on NISAR.

Nothing about SSLV-D1, GSLV Mark 2 with an IRNSS, or a GSLV Mark 3 commercial launch?
