Tiny Plasma Jets on Sun Identified as Key Drivers of Solar Wind
Observations from ESA’s Solar Orbiter have revealed that tiny plasma jets, known as picoflares, are responsible for both the fast and slow components of the solar wind. The discovery challenges previous assumptions that different mechanisms drive these solar wind types. With further research, scientists hope to refine space weather predictions, p...

May 2024 Solar Storm Triggers Unusual Radiation Belts, Raising Space Safety Concerns
A significant solar storm in May 2024 led to the creation of two temporary radiation belts, detected by the CIRBE satellite in June. One belt contained high-energy electrons, while the other was rich in protons, a rare occurrence. While the electron belt dissipated in three months, the proton-dominated belt remains, potentially affecting space miss...

NASA, General Atomics Test Nuclear Fuel for Faster Mars Missions
NASA and General Atomics conducted key tests on nuclear reactor fuel at Marshall Space Flight Center. The fuel was exposed to extreme temperatures to assess its viability for nuclear thermal propulsion. With successful results, the technology could enable faster space travel, reducing risks for astronauts on long-duration missions. NASA and DARPA a...

Astronaut Vision Changes in Space, Pose Risks for Mars Exploration
Reports indicate that 70 percent of astronauts on extended ISS missions develop vision issues linked to spaceflight-associated neuro-ocular syndrome (SANS). The condition, caused by fluid shifts in microgravity, leads to optic nerve swelling, vision impairment, and structural eye changes. While symptoms often reverse upon return to Earth, the long-...

Astronauts' Vision Problems Linked to Prolonged Space Exposure, Posing Risks for Mars Missions
Extended space missions, such as those aboard the International Space Station (ISS), are linked to significant ocular changes in astronauts. These changes, collectively termed spaceflight-associated neuro-ocular syndrome (SANS), affect around 70 percent of astronauts. A recent study found reductions in ocular rigidity, intraocular pressure, and ocu...

NASA Astronaut Sunita Williams Health Deteriorates Amid Extended ISS Mission, New Photo Raises Concern
NASA astronaut Sunita Williams, stranded on the ISS since early June due to Boeing’s Starliner malfunction, has sparked health concerns after a recent photo showed visible weight loss. Dr Vinay Gupta, a Seattle-based pulmonologist, highlighted signs of potential caloric deficit and physiological stress caused by prolonged time in space. Williams...

"It Was Awesome": NASA Astronauts Replace Faulty Antenna During Spacewalk
Two NASA astronauts completed a 6-1/2 hour spacewalk on Thursday to replace a faulty antenna on the International Space Station, a mission NASA said carried slightly higher risk posed by orbital debris left from a Russian missile test weeks ago.
