Rising Satellite Traffic in Low Earth Orbit Sparks Collision Risk Concerns
A new study in Acta Astronautica warns that Low Earth Orbit is becoming dangerously congested. Since 2019, the number of satellites performing more than ten collision-avoidance maneuvers per month has risen sevenfold. With nearly 25,000 tracked objects and more launches planned, scientists fear a chain-reaction risk and call for stronger global coo...

ISRO Chairman Opens OrbitAID Research Facility to Boost On-Orbit Servicing in India
ISRO chief Dr. V. Narayanan inaugurated OrbitAID’s new Bengaluru lab, India’s largest commercial test site for on-orbit refueling and docking. The 6,500-sq-ft facility features advanced cleanrooms and RPOD testbeds. OrbitAID’s technology aims to extend satellite lifespans, reduce space debris, and create a circular, sustainable space economy.

Rain Data Doesn't Support Claim Cloudburst Caused Uttarkashi Disaster: Experts
A cloudburst in the upper catchment of the Kheer Ganga river is widely believed to have triggered the flash flood in Uttarkashi's Dharali, but experts feel the amount of rain the Uttarkashi district received on Tuesday was not enough.

Dead NASA Satellite Relay 2 May Have Caused Mysterious 2024 Radio Burst
In June 2024, a mysterious 30-nanosecond radio burst baffled scientists — until they traced it back to a surprising source: Relay 2, a NASA satellite offline since 1967. Researchers believe the signal could have been triggered either by a micrometeorite impact or an electrostatic discharge. The discovery, detailed in a new preprint study, highlig...

Soviet Venus Probe Kosmos-482 Re-enters Earth’s Atmosphere After 52 Years, Location Unclear
A failed Soviet Venus probe from 1972 re-entered Earth’s atmosphere in May, yet tracking its final descent baffled experts. Despite decades of observation, differing models and unpredictable atmospheric conditions prevented precise predictions. Scientists now see Kosmos-482 as a case study in the enduring challenges of satellite reentry and the n...

Soviet Venus Lander Kosmos 482 Crashes to Earth After 53 Years in Orbit
Off-page Excerpt: Kosmos 482, a failed Soviet Venus lander launched in 1972, finally fell to Earth on May 10 after 53 years in orbit. Reentry estimates vary, but experts believe the probe likely splashed into the Indian Ocean. Designed to withstand Venus’s atmosphere, it may have reached Earth’s surface intact, renewing global concerns over un...

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...

Rocket Lab Delays IoT Satellite Launch to Ensure Safe Trajectory in Space
Rocket Lab has postponed its "IOT 4 You and Me" mission to avoid potential collisions with satellites and the International Space Station. This mission, set to deploy five IoT satellites, marks Rocket Lab's first launch of 2025. The company is taking extra precautions to monitor space traffic and ensure the rocket follows a safe trajectory. The sat...

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...
