NASA-ISRO Synthetic Aperture Radar (NISAR) – Recent Updates

August 14, 2024

The NASA-ISRO Synthetic Aperture Radar (NISAR) mission, a joint project between NASA and the Indian Space Research Organisation (ISRO), has encountered delays, pushing its launch to after February 2025. This mission is focused on improving our understanding of environmental changes and natural hazards through advanced radar imaging.

Reasons for Delay

The delay is mainly due to two reasons: challenges related to the satellite’s orbit and the need to make adjustments to the spacecraft’s antenna. A key launch period from early October 2024 to early February 2025 was missed because of temperature fluctuations that could have affected the satellite’s performance.

Technical Considerations

To address these temperature issues, NASA is making adjustments to the radar antenna reflector in California. They are applying a special coating to prevent the antenna from overheating, ensuring it will work reliably when it is deployed in space. Once this work is finished, the reflector will be sent back to India to be reattached to the spacecraft. NASA and ISRO are working closely together to determine a new date for the launch. This project highlights the strong collaboration between the two space agencies, with each bringing cutting-edge radar technology to the table.

Mission Objectives

Even with the delays, the mission’s goals are still highly important for global climate research. The NISAR satellite is designed to track changes in ecosystems, study the stability of ice sheets, and provide valuable data on natural disasters like earthquakes and tsunamis. The information collected will be crucial for scientific studies and for planning responses to disasters.

Facts About NASA

NASA was created in 1958, originally starting as an organization called NACA.
In 1969, NASA’s Apollo 11 mission made Neil Armstrong the first person to walk on the Moon.
NASA launched the Voyager spacecraft in 1977, which carry golden records with sounds and images from Earth.
NASA ran the Space Shuttle program from 1981 to 2011, completing 135 missions during that time.
In 2012, NASA’s Mars rover, Curiosity, landed on Mars to explore the planet.
The Hubble Space Telescope, launched in 1990, has greatly improved our knowledge of the universe.

Facts About ISRO

The Indian Space Research Organisation (ISRO) was established in 1969.
ISRO launched its first satellite, Aryabhata, in 1975.
In 2014, ISRO’s Mars Orbiter Mission, called Mangalyaan, made India the first Asian country to reach Mars.
In 2017, ISRO set a world record by launching 104 satellites in one mission.
ISRO’s Polar Satellite Launch Vehicle (PSLV) is known for being very reliable.
ISRO also created the GSLV Mk III rocket, which can carry heavier loads into space.
