The SpaceX Dragon cargo capsule successfully undocked from the International Space Station (ISS) on February 26, 2025, after a six-month orbital stay, having delivered approximately 5,000 pounds of supplies and scientific gear to the astronauts. The mission marked a significant milestone in the ongoing partnership between NASA and SpaceX for commercial resupply services.
The Artemis 2 mission has been delayed until at least April 1 due to a helium pressurization issue with the SLS rocket, which was rolled back to the Vehicle Assembly Building for repairs. The setback is a significant one, but NASA is working to resolve the problem and ensure the success of the mission.
Using the Atacama Large Millimeter/submillimeter Array, astronomers have captured a highly detailed image of the Central Molecular Zone at the heart of the Milky Way galaxy, providing new insights into the region's structure and star formation. This achievement marks a significant milestone in our understanding of the galaxy's central regions.
On February 25, 2026, SpaceX successfully launched its 500th Starlink satellite of the year from Vandenberg Space Force Base, marking a significant milestone in the company's efforts to expand its constellation of broadband satellites. This launch brings the total number of Starlink satellites in low Earth orbit to over 3,000, further solidifying SpaceX's position as a leader in the global satellite internet market.
On February 25, 2026, Rocket Lab will launch a hypersonic vehicle called DART AE, powered by a 3D-printed scramjet engine, as part of the Cassowary Vex mission sponsored by the US military. The launch aims to test the capabilities of the DART AE demonstrator and its Spartan scramjet engine.
The Artemis 2 mission, aiming to send four astronauts on a 10-day trip around the moon, has been delayed until April 2026 due to a helium system issue with the Space Launch System (SLS) rocket. The rocket is being rolled back to the Vehicle Assembly Building (VAB) for repairs.
The sun's visible disk has been free from sunspots for the first time since June 2022, indicating a potential shift towards a quieter phase in the current solar cycle. This development has significant implications for space weather and the broader aerospace industry.
Scientists have discovered a unique gravity anomaly beneath Antarctica, providing valuable insights into the Earth's deep interior and its dynamic processes. This phenomenon, known as the Antarctic Geoid Low, offers a rare glimpse into the slow-moving currents of rock that shape our planet.
In his recent State of the Union address, US President Donald Trump discussed the country's military space capabilities, praising the U.S. Space Force as a great fighting force, but did not mention NASA's upcoming Artemis 2 moon mission. The address highlighted the administration's focus on military space initiatives, while omitting key details about the nation's civilian space program.
A technical glitch in the helium flow system of the Space Launch System (SLS) rocket has prompted NASA to roll back the Artemis 2 moon rocket to the Vehicle Assembly Building (VAB), marking a significant setback for the highly anticipated mission. The decision comes after a series of wet dress rehearsals, including one that was cut short due to a leak of liquid hydrogen propellant.
NASA has postponed the launch of its Artemis II mission until April 2026 due to a helium flow issue with the Space Launch System (SLS) rocket, requiring the vehicle to be rolled back to the Vehicle Assembly Building for repair. The mission, a crucial step towards returning humans to the lunar surface, will now take place several months later than initially planned.
Boeing engineers have successfully demonstrated a large language model running on commercial off-the-shelf hardware, enabling the examination of telemetry and natural language reporting on satellite health. This achievement has significant implications for enhancing satellite autonomy and simplifying operations.
The US Space Force is set to undergo significant expansion over the next decade, potentially doubling in size to meet increasing operational demands and a broadening mission set. This growth will be driven by the need for enhanced satellite-based services, space-based targeting capabilities, and on-orbit servicing.
The US Space Force is seeking input from industry stakeholders on the development of in-orbit refueling services, aiming to establish a logistics network by 2030. This initiative has significant implications for the broader aerospace industry, enabling extended satellite lifetimes and more efficient space operations.
On February 24, 2026, SpaceX successfully launched 29 Starlink V2 Mini satellites into low Earth orbit using its Falcon 9 rocket from Cape Canaveral Space Force Station. This launch marks the company"s 18th mission of the year in support of its growing broadband internet satellite constellation.
Researchers using the European Southern Observatory's Very Large Telescope have captured a striking image of the binary star system AFGL 4106, which is nearing the end of its life and shedding vast amounts of gas and dust into space. This observation provides valuable insights into the complex interactions between stars in binary systems and their impact on surrounding interstellar material.
The Shenzhou-20 crew was forced to alter their return plans due to cracks found in their spacecraft's viewport caused by space debris, ultimately returning to Earth on an alternative vehicle. The incident highlights the risks posed by space debris to operational spacecraft.
NASA has delayed the launch of its Artemis II mission, which aims to send four astronauts around the moon, due to a helium system issue with the Space Launch System rocket. The launch is now postponed until at least April 1, 2026, as the rocket is rolled back to its hangar for repairs.
China’s Shenlong spacecraft, a reusable space plane, has launched on its fourth orbital mission from the Jiuquan Satellite Launch Center, aiming to test technologies for more convenient and affordable access to space.
