Since the launch of the Chandrayaan-3 mission on July 14, NASA ground stations have been monitoring the spacecraft’s health. NASA's Deep Space Network provided telemetry and tracking coverage during the powered descent phase from their Deep Space Stations. But this is not the first time, or the last time that we have seen a collaboration between ISRO and NASA.

00:00 Since the launch of the Chandrayaan-3 mission on July 14, NASA ground stations have been
00:05 monitoring the spacecraft's health.
00:08 NASA's Deep Space Network provided telemetry and tracking coverage during the powered descent
00:14 phase from their deep space stations at Canberra and Madrid.
00:18 But this is neither the first time nor the last time that we have seen a collaboration
00:23 between ISRO and NASA.
00:26 In July, India decided to join the Artemis Accords, which is an agreement that brings
00:30 together like-minded nations in the field of civil space exploration.
00:34 Under this, NASA and ISRO have agreed to collaborate on a joint mission to the International Space
00:40 Station in 2024.
00:41 The Accords are part of an American-led initiative to return humans to the Moon by 2025 and eventually
00:48 expand space exploration to Mars and beyond.
00:51 According to NASA, these Accords are designed to shape and govern the exploration and utilization
00:57 of outer space in the modern era.
01:00 The ISRO-NASA collaborative venture will witness the convergence of expertise and resources
01:06 from both the nations in a remarkable journey towards the International Space Station.
01:11 NASA and ISRO are developing a strategic framework for human-spaceflight cooperation.
01:18 Besides this, there is NISAR, which is a joint Earth-observing mission between NASA and ISRO.
01:24 It began in September of 2014, when NASA and ISRO signed a partnership to collaborate on
01:29 and launch NISAR.
01:32 The mission is targeted to launch in 2024.
01:35 NASA is providing the mission's radar, a high-rate communications subsystem for science
01:39 data, GPS receivers, a solid-state recorder and a payload data subsystem.
01:45 ISRO is providing the spacecraft bus, the S-band radar, the launch vehicle and associated
01:49 launch services.
01:50 NISAR aims to make global measurements of the causes and consequences of land-surface
01:57 changes using advanced radar imaging.
02:00 One of the top priorities of this survey is to gain data and insight into three areas
02:04 of Earth science, namely ecosystems, deformation of Earth's crust, and cryospheric sciences.
02:12 ISRO has identified science and applications that will be complementary to the primary
02:17 mission.
02:18 It will hail India with agricultural monitoring, studying landslides, Himalayan glacier studies,
02:23 soil moisture, coastal processes, coastal winds and monitoring climate disasters.
02:29 A second radar frequency has been added to the mission to better fulfil these requirements
02:33 specific to India.
02:34 NISAR will be the first satellite mission to use two different radar frequencies to
02:40 measure changes on Earth's surface less than a centimetre across.
