In the past six months, satellites in SpaceX’s Starlink megaconstellation performed nearly 50,000 collision-avoidance maneuvers, double the number from the previous half-year. According to SpaceX’s latest Semiannual Constellation Status Report, each Starlink satellite executed its thrusters an average of 14 times to avoid collisions with other satellites, spacecraft, and space debris. The constellation grew from about 5,100 to 6,200 satellites during this period. SpaceX also … Continue reading SpaceX Starlink satellites made 50,000 collision-avoidance maneuvers in the past 6 months

SpaceX and NASA are preparing to de-orbit the International Space Station (ISS) using an upgraded Dragon spacecraft designed for this purpose. NASA awarded SpaceX an $843 million contract to create a spacecraft capable of shifting the ISS, which weighs over 400 tons, into a controlled re-entry trajectory over an unpopulated ocean area. The ISS is scheduled for decommissioning after 2030, marking the end of its … Continue reading SpaceX Reveals Plan to Bring Down the ISS Using a Powered-Up Dragon Spacecraft

Scientists believe that if life exists on Saturn’s moon Enceladus or Jupiter’s moon Europa, detectable trace molecules might survive just beneath their icy surfaces. Both moons are thought to have vast liquid oceans that could harbor life, potentially containing complex organic molecules like amino acids and nucleic acids—key indicators of life. Although harsh solar radiation could destroy these molecules at the surface, new research suggests … Continue reading Signs of life could survive on solar system moons Enceladus and Europa

A study in Nature Astronomy reveals that China’s Chang’e-5 lunar probe detected trace amounts of water in moon soil samples. These findings, from a higher lunar latitude, suggest water may persist on the moon as hydrated salts. The Chang’e-5 mission, which returned to Earth in 2020, was the first lunar sample collection in 40 years, following the Chang’e-4’s 2019 landing on the far side of the moon, … Continue reading Chinese lunar probe finds water in moon samples

NASA has raised concerns about Asteroid 2011 MW1, a massive 380-foot object speeding towards Earth at nearly 29,000 km/h. Expected to make its closest approach on July 25, it will come within 2.4 million miles of Earth. Despite its size and proximity, NASA has assured that it poses no immediate threat, as the asteroid’s trajectory has been carefully monitored and it is not considered potentially … Continue reading NASA on alert as gigantic asteroid zooms too close to Earth, might turn catastrophic if moves from orbit

NASA announced Wednesday that it is canceling the Viper rover mission due to cost overruns and launch delays. Originally scheduled for late 2023, the mission faced setbacks from increased expenses and additional testing, impacting other projects. The rover was intended to explore the moon’s south pole, with about $450 million already invested. NASA will pursue lunar ice studies through other initiatives, the Associated Press has … Continue reading NASA cancels its moon rover mission, citing cost overruns and launch delays

NASA scientists have discovered pure sulfur on Mars for the first time, found by the Curiosity rover when it drove over a rock in the Gediz Vallis channel. This unexpected finding is notable because while sulfur-containing minerals have been observed on Mars, pure sulfur has not. The discovery, made on May 30, is significant because the conditions needed to form elemental sulfur are not known … Continue reading NASA’s Curiosity rover accidentally uncovered pure sulfur crystals on Mars

The sun is currently experiencing intense activity, firing off powerful solar flares. Sunspot AR3738, as it rotates out of view on the sun’s western limb, has emitted a strong X-class solar flare, the most powerful type.
