NASA’s GRACE Satellites Reveal Hidden Deep-Earth Process Behind Gravity Disturbance
Scientists have discovered a mysterious gravity signal detected by satellites nearly 20 years ago, which is linked to deep mantle changes beneath the Earth’s surface. The anomaly, lasting two years, coincided with a magnetic “jerk”, suggesting a rapid mass shift near the planet’s core.

SpaceX Moves Starship to Launch Pad for Final Version 2 Test Flight
SpaceX has moved its next Starship spacecraft to the launch pad at Starbase, Texas, signaling preparations for Flight 11. This test flight will be the last mission of Starship Version 2, following Flight 10’s success with splashdowns and satellite deployment.

GPS Interference Is On Rise. Here's What Can Be Done About It
GPS interference is on the rise, so you might be wondering how it works. And can anything be done about it? And perhaps most importantly do you need to worry?

China Advances Guowang Internet Constellation with Latest Satellite Launch
China has launched the eighth batch of satellites for its Guowang internet constellation, lifting off on Aug. 13 aboard a Long March 5B rocket from Wenchang Space Launch Center. Operated by state-owned China SatNet, Guowang aims to deploy about 13,000 satellites in low Earth orbit to compete with SpaceX’s Starlink. Each launch so far has carried ...

Starlink’s Unintended Signals Threaten Astronomical Research, Study Finds
Astronomers have raised concerns over Starlink’s unintended radio emissions interfering with space observation. A Curtin University study found emissions from SpaceX satellites impacting up to 30% of astronomical data. Experts urge updated regulations to protect radio astronomy, as current rules overlook these non-deliberate signals from satellit...

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...

Amazon's Kuiper Launches 27 Satellites, Eyes 2025 LEO Broadband Rollout
Amazon’s Project Kuiper is intensifying efforts to compete in the low Earth orbit (LEO) broadband race. With 27 satellites launched in April 2025 and plans for a 3,200-satellite constellation, Amazon has locked in dozens of launches across ULA, Blue Origin, Arianespace, and SpaceX. This move follows its successful 2023 prototypes and aligns with ...

Mysterious "Dead" Satellite Sends Powerful Signal to Earth After Decades
The radio pulse was blasted from a defunct satellite, Relay 2, which was an experimental communications satellite launched in 1964.

Seismic Mystery Solved: NASA’s SWOT Satellite Detects Greenland Mega-Tsunamis
In September 2023, a global seismic mystery puzzled scientists for nine days. New research now confirms it was caused by two mega-tsunamis triggered by landslides in East Greenland. The waves became trapped in a fjord, forming seiches that shook the Earth. Using cutting-edge data from NASA’s SWOT satellite, scientists detected these hidden waves ...

China's Most Advanced Bombers Seen On Disputed South China Sea Island
Satellite imagery shows China landed two of its most advanced bombers in the disputed Paracel islands in the South China Sea this month - a gesture that some analysts described as Beijing's latest signalling of its growing military capabilities.

NASA Satellite Detects Tree Leaf Changes as Early Volcano Eruption Warning Signal
NASA and Smithsonian scientists find that greener trees seen in satellite images may warn of upcoming volcanic eruptions. The change is linked to rising carbon dioxide emissions from magma, which trees absorb and display through greener leaves. This method could enhance early warning systems and improve public safety near active volcanoes.

NASA’s Lunar Trailblazer Moon Probe Struggles with Power and Signal Loss
NASA’s Lunar Trailblazer, launched on 26 February, has lost communication and is running low on power. The spacecraft, meant to detect water ice on the moon, has been unable to perform key trajectory corrections. Ground controllers are using the Deep Space Network and observatories to assess its position, but recovery remains uncertain. The missi...

Astronomers Spot New Cosmic Explosions 100 Times Brighter Than the Sun
Astronomers have discovered a new class of cosmic explosions, known as 'millinovas,' which are 100 times brighter than the Sun. These events, first identified in 2023, were observed in the Large and Small Magellanic Clouds, two satellite galaxies of the Milky Way. The millinovas are thought to occur when white dwarfs feed off a companion star, prod...

Russia's "Starlink Killer" Might Become A Nightmare For Ukraine, Elon Musk
In a major concern for Ukraine and its allies, as well as US billionaire Elon Musk, the Russian Military has reportedly developed an advanced system which could detect and locate signals from enemy UAVs that connect to satellite systems.
