India launches NASA-ISRO satellite to track climate threats from space
The NASA-ISRO Synthetic Aperture Radar, or NISAR satellite, is the first such collaboration between the Indian Space Research Organization and U.S. space agency NASA.
It took off from India's Satish Dhawan Space Centre at 1210 GMT atop a medium-lift rocket, marking a milestone in space cooperation and bolstering India's profile in low-cost, high-impact satellite missions.

NISAR is the world's first radar imaging satellite to use two radar frequencies – the L-band provided by NASA and the S-band developed by ISRO – to track minute changes in the Earth's surface, including movements as small as a centimeter, the space agencies have said.
The satellite, roughly the size and weight of a fully loaded pickup truck – was placed into a near-polar Sun-synchronous orbit approximately 747 km (464 miles) above Earth.
It will map the planet every 12 days using a 240-km-wide radar swath, offering data to scientists and disaster response agencies to monitor everything from glacier retreat in the Himalayas to potential landslide zones in South America.
'The potential applications from the satellite are huge, and the global scientific community is eagerly awaiting the satellite data for their respective research and usage,' ISRO Chairman V. Narayanan said after the launch.

'It is not going to be used by one or two countries. The entire globe is going to benefit from this great accomplishment,' he said, adding that the mission had brought the two space agencies much closer than ever before.
Casey Swails, NASA's deputy associate administrator, called the mission a 'pathfinder'.
'This Earth science mission is one of a kind and really shows the world what our two nations can do,' she said.

NISAR is expected to operate for at least five years.
The data it collects will be made freely available to users worldwide — a move aimed at enhancing transparency and accessibility in environmental research and hazard response.
The launch comes amid India's broader push to establish itself as a leading space power, following the success of its Chandrayaan-3 moon landing and its upcoming Gaganyaan human spaceflight, opens new tab programme.
India has said it aims to build its own space station by 2035 and send astronauts to the moon in partnership with other countries as part of a broader vision to expand commercial and scientific activities in space.

NASA Announces It Will Be Randomly Searching Employees
As NASA reels from massive budget cuts by Donald Trump's White House, the space agency seems to be clamping down hard on physical security measures. An internal memo shared by Keith Cowing, a former NASA astrobiologist who now blogs about the agency at NASA Watch, shows that all personnel and their property are now subject to random inspection by security officers. The random searches went into effect on July 30, the day the memo was sent out, and encompass the inspection of "individuals, belongings, and vehicles entering or exiting the premises" of all NASA centers. Employees at the NASA headquarters in Washington DC, sometimes called "the little White House," received a specific notice tailored to the facility. "When randomly selected in the West Lobby, individuals will be asked to walk through the metal detector," the memo declares, presumably addressing both incoming and outgoing workers. "In the East Lobby [home to the Earth Information Center], an officer will use a hand-held metal detector." "If the individual is carrying personal effects, those items will also be searched by the officer," it continues. Vehicles are likewise subject to random probes. "When randomly selected, individuals will be notified upon entry to pull over and asked to step out of the vehicle," the memo says. "Once the random search is complete, the individual will return to their vehicle and proceed to the parking garage. The estimated search time will be less than 5 minutes." That memo comes months after NASA was caught purchasing a license to use Clearview AI — a controversial digital surveillance startup — throughout its facilities. Random searches aren't necessarily unheard of in industries deemed critical for national development. Private companies like DOW Chemical, Genentech, and Lockheed Martin routinely engage in random employee inspections, often employing x-ray scanners, canines, and even autonomous drones to surveil workers. While the scrutiny may seem reasonable from a corporate point of view, random employee searches are legally dubious. They've led to lawsuits like Boutin v. Exxon Mobil Corp, in which a contract worker alleged Exxon had fired her in retaliation for complaining about sexual harassment on the job site, using a random inspection as justification. Some legal groups argue that employee inspections serve to reinforce employer's control over their workers, blurring the lines between personal and private property. Random searches are especially problematic, because the employer has no justification for suspecting the chosen workers of any type of misconduct. As far as NASA is concerned, the timing of the new security initiative is noteworthy, coming as thousands of senior employees are being asked to pack their bags and leave the agency for good. That in mind, it doesn't take a rocket scientist to see how NASA leadership could justify the move. For example, a career Extravehicular Activity Suit Systems Engineer might have few other job prospects outside of NASA, and insider secrets can fetch a pretty penny. (In 2023, a lawsuit filed in federal court accused Boeing of stealing "billions of dollars" worth of trade secrets related to NASA's Artemis program.) However, there's an easy way to prevent the leak of NASA secrets, as Cowing notes: "treat [your remaining workers] as the valuable individuals that they are — not sheep for you to scare whenever you get a memo from the White House."

White House Orders NASA to Destroy Important Satellite
The White House has instructed NASA employees to terminate two major, climate change-focused satellite missions. As NPR reports, Trump officials reached out to the space agency to draw up plans for terminating the two missions, called the Orbiting Carbon Observatories. They've been collecting widely-used data, providing both oil and gas companies and farmers with detailed information about the distribution of carbon dioxide and how it can affect crop health. One is attached to the International Space Station, and the other is collecting data as a stand-alone satellite. The latter would meet its permanent demise after burning up in the atmosphere if the mission were to be terminated. We can only speculate as to why the Trump administration wants to end the missions. But considering president Donald Trump's staunch climate change denial and his administration's efforts to deal the agency's science directorate a potentially existential blow, it's not difficult to speculate. Worse yet, the two observatories had been expected to function for many more years, scientists working on them told NPR. A 2023 review by NASA concluded that the data they'd been providing had been "of exceptionally high quality." The observatories provide detailed carbon dioxide measurements across various locations, allowing scientists to get a detailed glimpse of how human activity is affecting greenhouse gas emissions. Former NASA employee David Crisp, who worked on the Orbiting Carbon Observatories' instruments, told NPR that current staffers reached out to him. "They were asking me very sharp questions," he said. "The only thing that would have motivated those questions was [that] somebody told them to come up with a termination plan." Crisp said it "makes no economic sense to terminate NASA missions that are returning incredibly valuable data," pointing out it costs only $15 million per year to maintain both observatories, a tiny fraction of the agency's $25.4 billion budget. Other scientists who've used data from the missions have also been asked questions related to terminating the missions. The two observatories are only two of dozens of space missions facing existential threats in the form of the Trump administration's proposed 2026 fiscal year budget. Countless scientists have been outraged by the proposal, arguing it could precipitate an end to the United States' leadership in space. Lawmakers have since drawn up a counteroffer that would keep NASA's budget roughly in line with this year's. "We rejected cuts that would have devastated NASA science by 47 percent and would have terminated 55 operating and planned missions," said senator and top appropriator Chris Van Hollen (D-MD) in a July statement, as quoted by Bloomberg. Simply terminating Earth-monitoring missions to pursue an anti-science agenda could be a massive self-own, lawmakers say — and potentially breaking laws as well by overriding existing, allocated budgets. "Eliminating funds or scaling down the operations of Earth-observing satellites would be catastrophic and would severely impair our ability to forecast, manage, and respond to severe weather and climate disasters," House representative and Committee on Science, Space and Technology ranking member Zoe Lofgren (D-CA) told NPR. "The Trump administration is forcing the proposed cuts in its FY26 budget request on already appropriated FY25 funds," she added. "This is illegal."
