NASA and L3Harris Technologies have successfully tested the second new RS-25 engine for the Artemis V mission. The engine, built with advanced 3D printing that cuts costs by 30%, fired for 500 seconds at 111% power, ensuring a sustainable engine supply for America's return to the Moon.

European astronomers using ESA's XMM-Newton and LOFAR telescopes have confirmed the first direct sighting of a coronal mass ejection (CME) from another star. The explosion from a red dwarf 40 light-years away raced at 2,400 km per second, threatening the habitability of any nearby planets and opening a new era in stellar space weather observation.

Researchers led by Daniel Klocke from Max Planck Institute have developed an Earth model with 1.25-kilometer resolution using 672 million calculated cells. The system uses 20,480 GH200 superchips to simulate 145.7 days in one day, combining "fast" weather systems through the ICON model with "slow" climate processes. Running on JUPITER and Alps supercomputers in Germany and Switzerland, the breakthrough calculates nearly 1 trillion degrees of freedom, far surpassing traditiona

ISRO has successfully tested the critical parachute system for its Gaganyaan human spaceflight mission, validating the 10-parachute sequence under extreme conditions. A 2.5-tonne module was dropped from 2.5 km by an Indian Air Force IL-76, confirming the system can ensure astronaut safety during descent.

China is launching a rescue mission for three astronauts stranded on the Tiangong space station after their Shenzhou-20 capsule was hit by orbital debris. The Shenzhou-22 will now retrieve commander Chen Dong and his crew, marking the first use of China's "rolling standby" rescue system established in 2021.

Yonsei University astronomers led by Professor Young-Wook Lee have published evidence that the universe's expansion is now decelerating, challenging the Nobel-winning dark energy acceleration theory. Their study of 300 galaxies corrects a key bias in supernova measurements and could mark a major paradigm shift in cosmology.

California company Vast has launched the Haven Demo, a key test satellite for its planned Haven-1 commercial space station. Launched via SpaceX, the demo will validate critical systems for six months ahead of the station's planned 2026 debut, which will host a crew of four aboard a SpaceX Crew Dragon.

The European Space Agency is funding the HOBI-WAN project to create astronaut food from air and urine. With OHB System AG and Solar Foods, ESA will test protein production in microgravity, enabling future Moon and Mars missions without Earth resupply.

Oxford University and Southwest Research Institute researchers discovered Enceladus loses heat from both poles, confirming the icy moon's ocean has long-term thermal stability for life. The 54 gigawatt heat output matches tidal heating predictions, creating a balanced environment where life could develop.

Northrop Grumman is collaborating with Luminary Cloud and NVIDIA to apply Physics AI for designing spacecraft thrusters. This technology could dramatically accelerate hardware development, potentially scaling to design entire spacecraft in the future.

Chinese scientists at the Institute of Mechanics have developed a breakthrough inflatable space module, advancing China's bid to build orbital factories. Director Yang Yiqiang says the technology will enable direct manufacturing in space, a key capability in the global race for economic dominance in orbit.

In a landmark discovery published in Nature on September 3, researchers led by Prof. SUN Daoyuan and Prof. MAO Zhu from the University of Science and Technology of China, together with international collaborators, have provided the first seismic evidence for a solid inner core (IC) on Mars. By analyzing data from NASA’s InSight mission, the team estimated the Martian inner core’s radius to be about 600 kilometers and found it to be composed mainly of a crystallized iron-nicke

Astronomers have spotted the brightest black hole flare that emitted the power of 10 trillion suns. It's also the most distant flare of this type ever detected. The flare came from a supermassive black hole that’s 10 billion light years away. The flare was discovered using the Zwicky Transient Facility (ZTF). The flare erupted from the supermassive black hole at the heart of an Active Galactic Nucleus (AGN) designated J2245+3743. This flare came from something called a “Tidal

Astronauts aboard China's Tiangong space station have enjoyed the world's first orbital barbecue, baking chicken wings and steak in a specialized hot air oven. The historic meal occurred during a six-person crew handover just before the previous crew's return was delayed due to a suspected space debris strike.

Chinese researchers at DFH Satellite Co. have developed a revolutionary space power system that generates 2.6 megawatts with microsecond precision. Led by senior engineer Su Zhenhua, this breakthrough solves a decades-old power dilemma, potentially enabling practical particle beam weapons and other directed energy systems for space warfare.

Facing pressure from NASA, SpaceX has revealed a simplified lunar lander based on its Starship rocket. The new design abandons a complex orbital refueling plan, slashing the number of required launches from up to 30 to less than 10 to achieve a crewed Moon landing and speed up the Artemis program timeline.

Astronomers from the University of Warwick and UCL have found that ageing red giant stars are likely destroying their innermost planets. The study of nearly half a million star systems reveals a three-fold decrease in close-orbiting giant planets around red giants, providing direct evidence for planetary engulfment. Lead researcher Dr. Edward Bryant described the process as a gravitational "tug-of-war" that drags planets to their doom.

Chinese astronauts host the first-ever “space BBQ” aboard Tiangong Station. Using a new electric oven designed for microgravity cooking. Astronauts grill skewered meat and vegetables in zero gravity. The food stays secured with magnetic trays and mesh covers. Crew watches as the oven’s timer counts down from 20 minutes. The cabin fills with laughter as the aroma spreads through Tiangong. Freshly cooked BBQ is shared and enjoyed together — a space first! A small step for food,

China National Space Administration (CNSA) has made first-ever contact with NASA to coordinate satellite collision avoidance, reversing years of established practice. NASA Space Sustainability director Alvin Drew announced the breakthrough at the International Astronautical Congress, signaling new cooperation in space traffic management.

China has delayed the return of astronauts Chen Dong, Wang Jie, and Chen Zhongrui from the Tiangong space station after a suspected space debris impact. The Shenzhou-20 crew will remain in orbit while safety checks are conducted, highlighting the real-time risks of orbital debris.
