Farm Fires Didn't End, They Just Moved To Afternoon: Satellite Data Analysis
Claims of a nearly 90% drop in stubble burning in Punjab and Haryana - a key contributor to pollution in Delhi-NCR - have been challenged by a new multi-satellite analysis, revealing that the decline is a result of a gap in India's monitoring system.

Volcanic Ash Missed India, But Pollution Risks Haven't: Doctors Warn, Share Tips
Satellite data confirms that the Ethiopian volcanic ash plume passed over parts of India but never reached ground-level concentrations harmful to people. However, Delhi's already severe pollution remains a major health threat.

60% Rise In Stubble Burning In 6 States In 24 Hours: Delhi Gasps For Air
The number of stubble burning incidents reported from six states -- Punjab, Haryana, Uttar Pradesh, Delhi, Rajasthan and Madhya Pradesh -- increased from 568 on November 7 to 911 a day later, as per the satellite remote sensing data.

Reflect Orbital Plans to Light Up Parts of Earth Where Sunlight Does Not Reach by April 2026
Reflect Orbital recently filed an application with the US FCC Space Bureau seeking permission to test launch its Earendil-1 non-geostationary orbit satellite. With this, the startup plans to begin redirecting the light emitted by the Sun with the help of glass-like satellites to dimly lit parts of the Earth. After closing its Series A round earlier...

Rising Rocket Launches May Delay Ozone Layer Recovery, Study Finds
A growing number of rocket launches may be compromising the ozone layer's recovery, according to new scientific studies. Chlorine and soot from rockets, along with pollutants released during satellite re-entry, could have long-term environmental impacts. The space industry is urged to act now—through regulation, innovation, and cleaner fuels—to...

NASA TEMPO Satellite to Continue Tracking Pollution Hourly from Space Until 2026
TEMPO, a collaborative space mission by NASA, NOAA, and the Smithsonian Astrophysical Observatory, is transforming air quality tracking across North America. Since 2023, it has delivered hourly, high-resolution pollution data from space, aiding researchers, health officials, and the public.

Scientists Chase Falling Satellite to Study Atmospheric Pollution from Spacecraft Reentries
In a rare airborne mission, scientists chased ESA's Cluster Salsa satellite as it reentered Earth's atmosphere. The fiery descent revealed emissions of lithium, potassium, and aluminum—chemicals that could impact the ozone layer and climate. With satellite reentries increasing, researchers aim to improve pollution models and plan further tracking...

SpaceX Starship Flight 7 Explosion Raises Concerns Over Air Pollution
The explosion of SpaceX’s Starship Flight 7 in mid-January has raised concerns among scientists about atmospheric pollution. The upper stage, weighing 85 tons without fuel, detonated at 90 miles (146 km) above Earth, potentially releasing 45.5 metric tons of metal oxides and 40 metric tons of nitrogen oxides. Experts warn these pollutants could i...

"Stubble Burning After 4 pm": Supreme Court Asks For 24x7 Data On Farm Fires
Supreme Court ordered 24x7 data on stubble burning in Punjab and Haryana after farmers started timing the crop burning with the overpass of NASA satellites over the region, a problem first highlighted by NDTV two weeks ago.
-
Space Debris Accumulation in the Stratosphere Threatens Major Environmental Risks
The growing presence of satellite space junk, as more satellites enter Earth's orbit, has raised concerns about environmental impacts. Pollution from burnt-up satellites contributes to changes in atmospheric chemistry, with metals like aluminium potentially harming the ozone layer. Scientists warn that satellite re-entries are contributing to a ris...

Centre Plans To Examine Burnt Area After Farmers Timing Crop Fires
Centre plans to clamp down on polluting farm fires by measuring the areas burnt instead of live blazes, after reports that farmers were burning paddy waste or stubble at times when satellites were not passing overhead.

Has There Been A Major Undercount Of Punjab Farm Fires? What Satellite Pics Show
Delhi and its adjoining areas are covered in smog and air quality is still in the 'very poor' category. The fourth stage of anti-pollution measures will remain in effect for three days as no sign of relief is expected soon.

Study Finds Industrial Aerosols May Cause Local Snowfall by Freezing Clouds
A new study led by the University of Tartu has shown that industrial emissions, particularly aerosol particles, can influence local snowfall by triggering ice formation in supercooled clouds. Using satellite and ground-based radar observations, researchers found that factories, including cement plants and power stations, may cause localised snow pl...
