NASA wraps up ISS-based AWE mission mapping Earth's weather ripples into space weather

NASA's Atmospheric Waves Experiment (AWE) on the International Space Station has completed its data-collection phase, surpassing its planned two-year mission by gathering more than 80 million nighttime infrared images of atmospheric gravity waves generated by severe weather, showing how these waves propagate upward to influence space weather and potentially disrupt satellites and communications; AWE will be replaced on the station by CLARREO Pathfinder, and all observations will be publicly available for researchers and citizen scientists.

SpaceX Dragon Delivers 6,500 Pounds of Science to the ISS

A SpaceX Dragon cargo capsule autonomously docked with the International Space Station, delivering about 6,500 pounds of research and supplies including microgravity experiments, a wooden bone scaffold, and studies on red blood cells and the spleen, plus instruments to study space weather, planetary formation, and Earth–Moon radiation effects, underscoring SpaceX’s pivotal role in sustaining ISS research.

Five-Millisecond Time Gap: Relativity in Real Life on the ISS

Five-Millisecond Time Gap: Relativity in Real Life on the ISS

The ISS travels at about 17,500 mph, causing time to pass slightly slower up there; after 340 days in orbit, Scott Kelly was about 5 milliseconds younger than his Earthbound twin Mark. The effect is real and purely relativistic, with gravity counteracting some aging, but the velocity effect dominates on the station. NASA studied the twin pair to track biological changes—telomeres lengthened, some gene expression stayed altered months after return, and various physiological shifts occurred—illustrating how long-duration spaceflight acts as a tiny, measurable form of time travel for humans.

ISS Captures Fiery Fireball as Space Debris Burns Up

An astronaut aboard the International Space Station photographed a bright fireball streaking through the upper atmosphere on April 27, 2026; the source is unclear—could be debris, a rocket body, a satellite, or meteoric material—though Progress 95 was not involved. NASA notes debris in the thermosphere can reenter and burn up due to atmospheric drag, with observations captured by a Nikon Z9 and shared via the Crew Earth Observations program.

Dragon cargo ship arrives at the ISS with new science payloads

SpaceX's CRS-34 Dragon cargo capsule docked autonomously at the International Space Station’s Harmony module at 6:37 a.m. EDT, carrying about 6,500 pounds of cargo and science experiments, including bone scaffolding research for osteoporosis, Earth-mimicking microgravity studies, red blood cell and spleen research, a charged-particle instrument to study near‑Earth space, and a device to measure sunlight reflected by Earth and the Moon. NASA astronaut Jack Hathaway and ESA astronaut Sophie Adenot watched from the Cupola as the crew prepares to unpack the science and supplies over the coming weeks and then return results, equipment and waste to Earth in mid‑June.

SpaceX fires up uncrewed Dragon cargo bound for ISS after weather delay

Three days after a weather delay, SpaceX launched an uncrewed Cargo Dragon on a Falcon 9 from Cape Canaveral, delivering about 6,500 pounds of supplies and science gear to the ISS for Expedition 74; the first stage landed successfully on its sixth flight, while Dragon will autonomously rendezvous and dock with the station to unload thousands of pounds of crew clothing, hardware and research equipment.

Cape Canaveral set for SpaceX NASA ISS resupply flight with sonic-boom return

SpaceX will launch a Falcon 9 from Cape Canaveral to deliver a Cargo Dragon to NASA's ISS as part of CRS-34; liftoff is scheduled for 7:16 p.m. ET on May 12 on a northeast trajectory, with the first stage aiming to land at LC-40 near the launch site, triggering a sonic boom over Brevard County. Weather forecasts show only a 35% chance of favorable conditions, and a backup liftoff at 6:50 p.m. on May 13 is planned if needed.

Space-grown mini-hearts beat Earth labs in production speed, study finds

Space-grown mini-hearts beat Earth labs in production speed, study finds

Researchers report that mini-hearts derived from human stem cells can be grown aboard the International Space Station at a far higher rate than on Earth, thanks to microgravity letting cells float freely without the need for aggressive stirring. This space-based production could yield thicker, more robust heart tissue and organoids for drug testing and potential future therapies, even as astronauts’ hearts undergo microgravity-induced changes. While space-grown tissues show promise and may eventually aid heart-disease research and transplants, human clinical use remains years away and further experiments—like on the SpaceX CRS-35 mission—are planned to scale and validate the approach.

ISS Captures Spectacular Fireball Likely Debris Reentry After Progress MS-34 Launch

ISS Captures Spectacular Fireball Likely Debris Reentry After Progress MS-34 Launch

NASA astronaut Chris Williams aboard the International Space Station photographed a dramatic fireball on April 27, 2026, likely caused by debris from a satellite or the upper stage of the Soyuz rocket related to the Progress MS-34 (Progress 95) mission. The fireball appeared as the Progress 95 cargo ship—launched April 25, docked two days later and to remain attached for about seven months—passed overhead near West Africa, with Williams noting a bright streak that split into a shower of pieces. Williams is a rookie aboard an eight‑month stay, sharing the ISS with SpaceX Crew-12 astronauts Jessica Meir and Jack Hathaway, along with Sophie Adenot and Andrey Fedyaev.

ISS Cracking Mystery Lingers After Air-Leak Seal

ISS Cracking Mystery Lingers After Air-Leak Seal

Air leaks in the ISS Zvezda module have been sealed, but a deeper structural mystery persists as NASA and Roscosmos probe root causes for the cracks in the PrK vestibule. The leading theories are high-cycle fatigue from pumps or environmental-assisted cracking. While containment measures and reduced pressurization are used to manage risk, there is no consensus on the severity or pervasiveness of the issue, highlighting challenges in maintaining aging infrastructure in orbit.

Canada's Kutryk Heading to the ISS on SpaceX Crew-13 in 2026

Canadian Space Agency astronaut Josh Kutryk is slated to fly to the International Space Station on SpaceX Crew-13 no earlier than September 2026, spending about six months aboard Expedition 75/76. This will mark the CSA’s first ISS rotation in eight years after the Boeing Starliner mishap led to reassignment of Starliner-1 crews. The crew also includes NASA astronauts Jessica Watkins and Luke Delaney and Roscosmos’ Sergey Teteryatnikov. Kutryk, a Royal Canadian Air Force colonel and veteran test pilot, will conduct Canadian-led experiments and maintenance on the station, continuing Canada’s Artemis-era involvement and Canadarm3 initiatives.
