As of May 2025, over 11,700 active satellites are orbiting the planet

Experts predict that the number of active satellites could climb to 100,000

Experts argue for slowing down satellite launches

Ever wondered how many satellites are circling Earth right now? As of May 2025, over 11,700 active satellites are orbiting the planet, and the number is rising at a record pace.

The dramatic surge is driven largely by private space firms like SpaceX, whose Starlink constellation alone accounts for over 7,400 satellites, or 60% of all active ones. In 2024, a rocket was launched every 34 hours on average, adding more than 2,800 new satellites to orbit in just one year, Live Science reported. 

According to astronomers and researchers, this satellite boom is just getting started. Experts predict that the number of active satellites could climb to 100,000 before stabilising, raising serious concerns about space traffic, debris, pollution, and interference with astronomy.

What’s Causing the Satellite Surge?

The rise of commercial ‘mega constellations’, massive networks of satellites designed to provide global internet and communication services, is a key factor. Besides SpaceX’s Starlink, other players like Amazon (Project Kuiper), OneWeb, and Chinese companies are aggressively expanding their presence in space.

The northeast US coast ha experienced increased flooding events recently.

A study links flooding to a slowdown of a major Atlantic current.

Up to 50% of flooding events from 2005 to 2022 were driven by a weaker AMOC.

The northeast coast of the US is witnessing more flooding events in recent years owing to the slowdown of a major current in the Atlantic Ocean that is boosting the sea level, a new study has shown. The Atlantic Meridional Overturning Circulation (AMOC) influences climate, weather and sea levels around the planet by transporting heat, salt and freshwater through the ocean, but scientists are worried that it is weakening.

The study published last week in the American Association for the Advancement of Science used data from tide gauges (an instrument used to monitor sea level change) and complex ocean models to calculate how the AMOC has affected flooding in the region.

“The US Northeast Coast (USNEC) has been identified as a hotspot for accelerated sea level rise over the North Atlantic (NA) Ocean in the most recent decades,” the study highlighted.

The findings showed that between 2005 and 2022, up to 50 per cent of flooding events along the northeastern coast were driven by a weaker AMOC.

With the climate is continuously changing and the atmosphere warming, scientists fear that fresh water from melting polar ice sheets could significantly disrupt or collapse the AMOC, leading to devastating consequences.

China launched 12 AI satellites to create the first space supercomputer network.

The satellites can perform 744 trillion operations per second in orbit.

Long March 2D rocket successfully deployed the satellites into their orbit.

China is building the world’s first supercomputer network in space, for which it launched 12 AI-powered satellites last week. The state-owned China Aerospace Science and Technology Corporation announced that the first of 2,800 satellites, part of its ‘Star Computing’ programme, were launched aboard a Long March 2D rocket and successfully deployed into orbit.

Each of the 12 satellites can process up to 744 trillion operations per second, having transfer rates up to 100 gigabits per second. The satellites are also equipped with a space-based AI model with eight billion parameters, capable of processing raw satellite data directly in orbit.

“The Long March 2D carrier rocket successfully sent the space computing satellite constellation into the predetermined orbit. The launch mission was a complete success,” the agency said.

“The space computing satellite constellation is the first constellation of the ‘Star Computing’ program.”

The “Three-Body Computing Constellation” will function as a space-based data processing network capable of computing vast amounts of information directly in orbit, without relying on any Earth-based infrastructure.

It will also be more powerful than any other supercomputer system on Earth, as it wouldn’t need the costly cooling systems that Earth-based computing systems require. According to estimates by the International Energy Agency, data centres globally could consume more than 1,000 terawatt hours of electricity by 2026, which is equivalent to Japan’s electricity use.

Currently, less than 10 per cent of the collected data by satellites is relayed to Earth, often with significant delays, according to a report in South China Morning Post. The new Chinese endeavour, however, aims to solve the limits of Earth-based data processing.

Researchers said that various factors contributed to satisfaction, but higher income didn’t correlate strongly with it, nor did the prestige of a job.

A new study identifies the most and least satisfying jobs worldwide.

Researchers analyzed data from 59,000 individuals across 263 occupations.

Clergy, medical professions, and writing ranked highest in job satisfaction.

A new study has revealed the most and the least satisfying jobs in the world. For the study, researchers studied the data from the Estonian Biobank and analysed about 59,000 people and 263 occupations. They asked participants donating blood for the biobank project to complete a survey that asked about details of their job, salary, personality and their satisfaction with various aspects of life. The scientists from the University of Tartu in Estonia then used the details to identify the jobs that seem to give the most and the least fulfilment. 

The researchers found that the jobs that seem to give the most fulfilment include clergy, various medical professions and writing. Jobs that appear to make people least satisfied include working in kitchens, transport, storage and manufacturing, and being a survey interviewer or sales worker, the researchers said, per NewScientist. 

In terms of overall satisfaction, being a medical professional, psychologist, special-needs teacher, a sheet-metal worker or a ship engineer rated highly. However, being a security guard, survey interviewer, waiter, sales worker, mail carrier, carpenter, or chemical engineer ranked low on the list. 

Researchers said that various factors contributed to satisfaction, but higher income didn’t correlate strongly with it, nor did the prestige of a job. 

“I was expecting the job prestige to be more associated with satisfaction, but there was only a slight correlation,” said study author Katlin Anni. 

“Jobs with a higher sense of achievement are associated with higher satisfaction, and even lower-prestige jobs can be quite fulfilling,” she added.
