NISAR sees subtle changes in Earth’s land and ice surfaces. But how does it work? The SAR in NISAR stands for synthetic aperture radar, and it helps scientists “see” through clouds to track changes in cities, forests, and ice.

🌍 Historic Launch Ahead: ISRO Set to Launch NISAR, a joint satellite with NASA ! 🚀 On July 30, 2025 at 17:40 IST, ISRO’s GSLV-F16 will launch #NISAR, the first joint Earth observation satellite by ISRO & NASA, from Sriharikota. 🛰️ NISAR will scan the entire globe every 12 days, providing high-resolution, all-weather, day-and-night data. It can detect even subtle changes in Earth’s surface—like ground deformation, ice sheet shifts, and vegetation dynamics. The mission will support many critical applications including sea ice monitoring, ship detection, storm tracking, soil moisture changes, surface water mapping, and disaster response. 🤝 A milestone in over a decade of collaboration between ISRO & NASA/JPL. 🔗 More info: ISRO Website #NISAR #ISRO #NASA #GSLVF16 #EarthObservation

#WATCH | NASA-ISRO NISAR satellite onboard GSLV-F16 launched from Satish Dhawan Space Centre (SDSC) in Sriharikota, Andhra Pradesh NISAR, or NASA-ISRO Synthetic Aperture Radar is a joint venture of ISRO and NASA and has been designed to provide a detailed view of the Earth to observe and measure some of the planet's most complex processes, including ecosystem disturbances, ice-sheet collapse, natural hazards, sea level rise, and groundwater issues. Its radar, the first of its kind in space, will systematically map Earth, measuring changes of our planet's surface as small as a centimetre.

Radar satellites can see at night and through clouds They also can detect millimetre changes in some cases, from space (!) But I've found them really counter-intuitive, so I spent the last 6 months working on a video explaining how they work Watch:

The same satellite tech can track a convoy through dense cloud cover at night, flag a sinkhole weeks before it opens, catch a village built on a collapsing slope, and even map the inside of a pyramid from orbit. It's called Synthetic Aperture Radar (SAR), and a lot of the data is free. In this video I cover the physics, the commercial arms race, and the defense constellation that will track every moving vehicle on Earth by the 2030s. 0:00 - A convoy no camera can see 0:56 - What is Synthetic Aperture Radar? 2:02 - InSAR: sub-millimeter change detection 3:07 - They scanned inside a pyramid from space 4:20 - These cities are sinking faster than sea levels rise 5:00 - North American bridges are the worst on Earth 6:09 - An AI caught a village built on a landslide 7:50 - The commercial SAR arms race 9:01 - GMTI: tracking convoys in the dark 11:26 - NISAR: the billion-dollar SAR satellite 12:45 - The other side of this all Full video on YT on Bilawal Sidhu channel. Enjoy.

Congratulations India! Successful launch of #GSLV-F16 carrying the world’s first dual-band radar satellite #NISAR…a game changer in precise management of disasters like cyclones, floods etc. Also, it’s capacity to penetrate through fogs, dense clouds, ice layers etc make it a pathbreaking enabler for aviation and shipping sectors. The inputs from NISAR will benefit the entire world community…in the true spirit of “ Vishwabandhu”. Proud to be associated with the Department of Space at a time when Team ISRO is registering one global milestone after the other,under the supportive patronage of PM Narendra Modi.

Wow: Stephen A. Smith goes OFF on Democrats for going against ICE and President Donald Trump. "How come it was okay to celebrate ICE when Obama was in office — and you had networks literally traveling with ICE to show you the marvelous work that they were doing — but suddenly Trump is doing it and now it's a pariah and ICE needs to go and be completely banned?" "Why are sanctuary cities existing? Why do you get to implement laws that get you to ignore federal laws? How does that benefit our country?" Smith plans on running for office in the 2028 election.

NFL banned ICE from the Super Bowl. But protesters got in, handed out 25,000 “ICE OUT” towels, and marched right outside the stadium. How’s ICE the threat, but the agitators pushing political chaos get VIP access? America sees through it.

Sanctuary cities won’t work with ICE but then act shocked and complain when ICE does its job. A federal agent was shot in the head on Saturday because weak immigration enforcement let things spiral. The government is now stepping in and prioritizing sanctuary cities. Good.
