After a pair of Islamist bombings rocked the south-central Indian city of Hyderabad in 2013, officials rushed to install 5,000 CCTV cameras to bolster security. Now there are nearly 700,000 in and around the metropolis.

The most striking symbol of the city’s rise as a surveillance hotspot is the gleaming new Command and Control Center in the posh Banjara Hills neighbourhood. The 20-story tower replaces a campus where swarms of officers already had access to 24-hour, real-time CCTV and cell phone tower data that geolocates reported crimes. The technology triggers any available camera in the area, pops up a mugshot database of criminals and can pair images with facial recognition software to scan CCTV footage for known criminals in the vicinity.

The Associated Press was given rare access to the operations earlier this year as part of an investigation into the proliferation of artificial intelligence tools used by law enforcement around the world.

Police Commissioner C V Anand said the new command centre, inaugurated in August, encourages using technologies across government departments, not just police. It cost $75 million (roughly Rs. 620 crore), according to Mahender Reddy, director general of the Telangana State Police.

Facial recognition and artificial intelligence have exploded in India in recent years, becoming key law enforcement tools for monitoring big gatherings.

Police aren’t just using technology to solve murders or catch armed robbers. Hyderabad was among the first local police forces in India to use a mobile application to dole out traffic fines and take pictures of people flaunting mask mandates. Officers also can use facial recognition software to scan pictures against a criminal database. Police officers have access to an app, called TSCOP, on their smartphones and tablets that includes facial recognition scanning capabilities. The app also connects almost all police officers in the city to a host of government and emergency services.

Anand said photos of traffic violators and mask-mandate offenders are kept only long enough to be sure they aren’t needed in court and are then expunged. He expressed surprise that any law-abiding citizen would object.

“If we need to control crime, we need to have surveillance,” he said.

But questions linger over the accuracy and a lawsuit has been filed challenging its legality. In January, a Hyderabad official scanned a female reporter’s face to show how the facial recognition app worked. Within seconds, it returned five potential matches to criminals in the statewide database. Three were men.

Hyderabad has spent hundreds of millions of dollars on patrol vehicles, CCTV cameras, facial recognition and geo-tracking applications and several hundred facial recognition cameras, among other technologies, Anand said. The investment has helped the state attract more private and foreign investment, he said, including Apple’s development centre, inaugurated in 2016; and a major Microsoft data centre announced in March.

“When these companies decide to invest in a city, they first look at the law-and-order situation,” Anand said.

He credited technology for a rapid decrease in crime. Mugging for jewellery, for example, plunged from 1,033 incidents per year to less than 50 a year after cameras and other technologies were deployed, he said.

Hyderabad’s trajectory is in line with the nation’s. The country’s National Crime Records Bureau is seeking to build what could be among the world’s largest facial recognition systems.

Building steadily on previous government efforts, Prime Minister Narendra Modi and his Bharatiya Janata Party (BJP) have seized on the rise in surveillance technology since coming to power in 2014. His flagship Digital India campaign aims to overhaul the country’s digital infrastructure to govern using information technology.

The government has promoted smart policing through drones, AI-enabled CCTV cameras and facial recognition. It’s a blueprint that has garnered support across the political spectrum and seeped into states across India, said Apar Gupta, executive director of the New Delhi-based Internet Freedom Foundation.

“There is a lot of social and civic support for it too – people don’t always fully understand,” Gupta said. “They see technology and think this is the answer.”

How NASA Saved a Dying Camera Near Jupiter with Just Heat

NASA’s Juno spacecraft, in orbit around Jupiter, had a huge problem when its JunoCam imager started to fail after sitting through the planet’s harsh radiation belts for so many orbits. Designed to only last through the initial few orbits, JunoCam astonishingly endured 34 orbits. Yet by the 47th orbit, the effects of radiation damage became visible, and by the 56th orbit, images were almost illegible. With few alternatives and time slipping away before a close flyby of Jupiter’s volcanic moon Io, engineers made a daring but creative gamble. Employing an annealing process, they sought to resuscitate the imager by warming it up—an experiment that proved successful.

Long-distance fix

According to NASA, JunoCam’s camera resides outside the spacecraft’s radiation-shielded interior and is extremely vulnerable. After several orbits, it started developing damage thought to be caused by a failing voltage regulator. From a distance of hundreds of millions of miles, the mission team implemented a last-ditch repair: annealing. The technique, which subjects materials to heat in order to heal microscopic defects, is poorly understood but has been succeeding in the lab. By heating the camera to 77°F, scientists wished to reorient its silicon-based parts.

At first, efforts were for naught, but only days before the December 2023 flyby of Io, the camera unexpectedly recovered—restoring close-to-original image quality just in time to photograph previously unseen volcanic landscapes.

Radiation Lessons for the Future

Though the camera showed renewed degradation during Juno’s 74th orbit, the successful restoration has led to broader applications. The team has since applied similar annealing strategies to other Juno instruments, helping them withstand harsh conditions longer. Juno’s findings are now informing spacecraft design across the board. “We’re learning how to build radiation-tolerant systems that benefit both defense and commercial satellites,” said Juno’s principal investigator Scott Bolton. These findings would inform future missions, such as those visiting outer planets or working in high-radiation environments near Earth, in the Van Allen belts. Juno’s mission continues to pay dividends with unexpected innovations—a lesson in how a small amount of heat can do wonders.

NASA’s X-59 Moves Closer to First Flight with Advanced Taxi Tests and Augmented Vision

X-59 of NASA has been designed from the ground to fly at a faster speed of sound without making thunderous sonic booms, which are usually associated with supersonic flight. This 99-foot aircraft, which features a logically elongated design, jettisons the front windscreen and is now heading towards the runway. Pilots can see what is at the front through an augmented reality (AR) enabled closed-circuit camera system, which is termed by NASA as the External Vision System (XVS). NASA took control of an experimental aircraft and performed taxi tests on it during this month.

X-59’s Futuristic Design: Eliminating Sonic Booms with External Vision System

According to As per NASA, the test pilot Nils Larson, during the test, drove the X-59 at the runway by keeping a low speed. This is done to ensure the working of the steering and braking systems of the jet. Lockheed Martina and NASA would perform the taxi tests at high speed, in which the X-59 will move faster to make it to the speed at which it will go for takeoff.

Taxi tests are held at the U.S. Air Force’s Plant 42 facility in Palmdale, California. The contractors and the Air Force utilise the plant for manufacturing and testing the aircraft. Lockheed Martin has developed this aircraft, whose Skunk Works is found in Plant 42.

Taxi Tests at Plant 42: NASA and Lockheed Martin Prepare X-59 for First Flight

Some advanced aircraft of the U.S. military were developed to a certain extent at Plant 42, together with the B-2 Spirit, the F-22 Raptor, and the uncrewed RQ-170 Sentinel spy drone.

SOFIA airborne observatory aircraft, which is a flying telescope called Plant 42, home recently retired. The space shuttle of the agency is the world’s first reusable spacecraft; these were assembled and tested at the facility.

Such taxi tests have started over the last months. NASA worked in collaboration with the Japan Aerospace Exploration Agency for testing a scale model of the X-59 in the supersonic wind tunnel to measure the noise created under the aircraft.

Unusual Plasma Waves Above Jupiter’s North Pole Can Possibly Be Explained

In recent observations, NASA’s Juno spacecraft has significantly detected the presence of a variety of plasma waves. The emergence of these waves on Jupiter’s powerful magnetic field is projected to be surprising, as their existence was never marked in the planetary magnetospheres. However, scientists might have come out with an explanation. Furthermore, the current studies have been questioned by scientists surfacing the activity at the North Pole. The article below will exemplify the findings and shed light on the plasmas. 

Uncovering Mystery at Jupiter’s North Pole 

According to a paper published in the Physical Review Letters, the scientists have uncovered the explanation behind the presence of these strange waves. They mainly suspect that the formation of these waves lies behind their evolution as a plasma, which later transforms into something different. 

Inside Jupiter’s Plasmas and Their Variants 

Plasmas are best referred to as the waves that pass through the amalgamation of the charged particles in the planet’s magnetosphere.These plasma waves come across in two forms: One, Langmuir waves, which are high-pitched lights crafted with electrons, while the other, Alfven waves, are slower, formed by ions (heavy particles). 

About Juno’s Findings

As unveiled by the Juno, the findings turned out to be questionable after the scientists noted that in Jupiter’s far northern region, the plasma waves were relatively slower. The magnetic field is about 40 times stronger than the Earth’s, but scientists were shocked to witness the results as the waves were slower. To analyse this further, a team from the University of Minnesota, led by Robert Lysak, identified the possibility of Alfven waves transforming into Langmuir waves. Post studying the data extracted from the Juno, the researchers then began to compare the relationship between the plasma wave frequency and number. 

According to Lysak’s research team, near Jupiter’s north pole, there might be a potential pathway of Alfven waves, which are massive in numbers, transforming into Langmuir waves. Scientists are also predicting that the reason behind evolution might be strong electrons that are shooting upwards at a very high energy. This discovery was made in the year 2016. Considering the current findings, the researchers indicate that Jupiter’s magnetosphere may comprise a new type of plasma wave mode that occurs during high magnetic field strength.
