US media: US-India joint satellite to be launched on July 30!
The United States and India each took on 50% of the manufacturing tasks, and the satellite will be launched into space by India.
On July 23, the US publication "Space News" published an article.

The National Aeronautics and Space Administration (NASA) and the Indian Space Research Organisation (ISRO) will launch the NISAR Earth observation satellite on July 30.
NISAR (NISAR) will scan our planet, providing the most detailed and sensitive surface map ever, capable of detecting movements on the ground less than one centimeter.
This sensitivity and the comprehensive coverage of the Earth provided by NISAR are crucial for helping to prevent or mitigate changes ranging from earthquakes, volcanoes, land subsidence and expansion, as well as the movement, deformation, and melting of ice caps and glaciers, as well as tracking the impact of wildfires and floods.
NASA said, "These changes may be very small, but they can have significant impacts."
The two radar antennas are 12 meters long; when deployed, its size is approximately equivalent to a tennis court.
By flying on a precisely repeating orbit - which means it will pass over the exact same ground track every 12 days - NISAR will be able to combine its synthetic aperture radar with another technology called interferometry.
NISAR will be launched from the Sriharikota ISRO Satish Dhawan Space Centre on the southeastern coast of India aboard the Indian Geosynchronous Satellite Launch Vehicle (GSLV).
"NISAR is an equal 50/50 collaboration between the United States and India," said Edelstein.
NASA has spent $1.2 billion on this mission, particularly funding the L-band radar, antenna, and antenna boom.
ISRO provided the S-band transmitter, satellite platform, solar panels, and launch vehicle.
