China jumps ahead in the race to achieve a new kind of reuse in space

Two Chinese satellites have rendezvoused with one another more than 20,000 miles above the Earth in what analysts believe is the first high-altitude attempt at orbital refueling. China's Shijian-21 and Shijian-25 satellites, known as SJ-21 and SJ-25 for short, likely docked together in geosynchronous orbit some time last week. This is the conclusion of multiple civilian satellite trackers using open source imagery showing the two satellites coming together, then becoming indistinguishable as a

Man of Glass: Boccaccio: A Biography

In early June 1363, Giovanni Boccaccio received a letter that stung him deeply. Just a few days shy of his fiftieth birthday, he was then at the height of his creative powers. He had already penned at least a dozen major works, including the Decameron, any one of which would have assured him a place alongside Dante and Petrarch in the firmament of Italian literature. Although recent political upheavals had forced him to leave his native Florence, he was still writing feverishly. Yet to his frien

Artist in Residence on a Satellite

On February 3, 2024, at 11:06 a.m., the first Chinese art satellite, "SCA-1" (The first satellite of the Star Chain of Arts Project), was successfully launched into orbit near the sea area of Yangjiang, Guangdong, using the Long March 3B carrier rocket. The satellite's solar panels deployed normally, and the initial telemetry is normal. Among the thousands of satellites now orbiting above us, including scientific, meteorological, communication, and military satellites, there was a missing catego

Hackers abuse leaked Shellter red team tool to deploy infostealers

Shellter Project, the vendor of a commercial AV/EDR evasion loader for penetration testing, confirmed that hackers used its Shellter Elite product in attacks after a customer leaked a copy of the software. The abuse has kept going for several months and even though security researchers caught the activity in the wild, Shellter did not receive a notification. The vendor underlined that this is the first known incident of misuse since it introduced its strict licensing model in February 2023. "

Major Satellite Suddenly Disappears

A satellite designed to monitor human-made methane emissions has gone missing in space. Dubbed MethaneSAT, the $88 million spacecraft was launched into orbit aboard a SpaceX rocket in March 2024 and was expected to collect data on the potent greenhouse gas for at least five years. But for the past two weeks, the satellite's operators, the nonprofit Environmental Defense Fund, have been unable to establish contact. Now, in a final blow, mission control says that MethaneSAT has lost power, crus

How AI on Microcontrollers Works: Operators and Kernels

The buzz around “edge AI”, which means something slightly different to almost everyone you talk to, is well past reaching a fever pitch. Regardless of what edge AI means to you, the one commonality is typically that the hardware on which inference is being performed is constrained in one or more dimensions, whether it be compute, memory, or network bandwidth. Perhaps the most constrained of these platforms are microcontrollers. I have found that, while there is much discourse around “running AI

Major reversal in ocean circulation detected in the Southern Ocean

Satellite data processing algorithms developed by ICM-CSIC have played a crucial role in detecting this significant shift in the Southern Hemisphere, which could accelerate the effects of climate change. Thanks to data obtained from Earth observation satellites, an international team of scientists has detected an unprecedented phenomenon for the first time: a reversal in the ocean circulation of the Southern Ocean. The study, led by the National Oceanographic Center (NOC, United Kingdom), was r

Lost in Space: A ‘Game-Changing’ Emissions Satellite Just Went Dark

An $88 million satellite backed by billionaire Jeff Bezos is lost in space. MethaneSAT, designed to sniff out sources of methane emissions across the globe, only survived about 15 months in Earth’s orbit before meeting its untimely end. The Environmental Defense Fund (EDF), which launched the satellite in March 2024, announced its demise on July 1. The organization revealed that MethaneSAT suddenly went silent on June 20, and its mission operations team has been unable to re-establish contact e

Starlink Plans to Send 42K Satellites Into Space. That Could Be Bad News for the Ozone

Satellites like the ones used for Starlink's internet service could be depleting the Earth's ozone layer when they're deorbited, according to a study funded by NASA and published in Geophysical Research Letters in June. 2024. When Starlink's satellites reach the end of their lives, they burn up in the Earth's atmosphere and leave behind small particles of aluminum oxide. These travel down into the ozone layer, which absorbs harmful ultraviolet radiation. Researchers from the University of South

The End of Wireless Dead Zones? T-Mobile’s Starlink Service Launches in 3 Weeks

Imagine being able to send a text, video or voice recording from the remotest corners of the country. That's the future T-Mobile envisions, as its partnership with SpaceX’s Starlink satellite service gets ready to launch on July 23. The alliance will provide direct-to-cell messaging service, called T-Satellite, which will also be available to AT&T and Verizon cellphone customers. T-Mobile says its goal is to “eliminate mobile dead zones for good” by utilizing 657 Starlink satellites that will b

Nearly 500 Starlink Satellites Have Incinerated in Earth's Atmosphere So Far This Year

According to a filing with the Federal Communications Commission on Tuesday, 472 Starlink satellites burned up in the atmosphere between December 2024 and May 2025, as SpaceX deorbited around 6% of its active fleet. Starlink satellites are built to last around five years. After that, they're steered into the Earth's atmosphere to burn up. SpaceX, the rocket company owned by Tesla and X CEO Elon Musk, launched the first Starlink satellites in 2019, which means we're now seeing its first full-sca

Bezos-funded satellite tracking methane emissions loses power in space

MethaneSAT, the Environmental Defense Fund (EDF) methane-tracking satellite backed by the Bezos Earth Fund, is lost in space. Its ground team lost contact with the spacecraft on June 20 but tried to reestablish a connection until it learned in the morning of July 1 that MethaneSAT had lost power altogether. The team believes that the satellite is likely not recoverable. MethaneSAT collected data on methane emissions that have previously been untrackable in an effort to combat climate change. Met

Xbox Elite Wireless Controller 2 Is Overkill for Most People, but Still Delivers an Epic Gaming Experience

The Xbox Elite Wireless Controller Series 2 (or Elite 2 for short) has arguably been the industry gold standard for a pro-level game controller for the past decade.

Airplane Wi-Fi Is Now … Good?

Expensive and erratic, in-flight Wi-Fi has been more of a punchline than a pipeline over the past decade. But 2025 has marked a sea change for the skies: the rollout of fast, and free, connectivity on most of the world’s major airlines. Satellite technology has enabled leaps in speed and bandwidth. SpaceX’s Starlink network of low Earth orbit satellites, for example, can deliver a connection capable of downloading more than 200 megabits per second—twice as fast as most basic home internet plans

Pentagon may put SpaceX at the center of a sensor-to-shooter targeting network

The Trump administration plans to cancel a fleet of orbiting data relay satellites managed by the Space Development Agency and replace it with a secretive network that, so far, relies primarily on SpaceX's Starlink Internet constellation, according to budget documents. The move prompted questions from lawmakers during a Senate hearing on the Space Force's budget last week. While details of the Pentagon's plan remain secret, the White House proposal would commit $277 million in funding to kick o

Trump’s ‘Obliterated’ Claim on Iran Just Became His Latest Meme Disaster

In his June 21 televised address from the White House, President Donald Trump declared that the U.S. had “obliterated” Iran’s nuclear program following airstrikes on three of its nuclear sites. The word was meant to project power, certainty, and victory. Instead, it has gone viral for all the wrong reasons. Within days, “obliterated” morphed into an online punchline, mocked by critics and meme-makers across social media platforms. It has become the latest in a long line of Trumpian catchphrases
