Apr. 3, 2026 — A new concept suggests SpaceX’s Starship could revolutionize a future mission to Uranus, one of the solar system’s most overlooked planets. By refueling in orbit and helping slow the spacecraft on arrival, it could cut travel time nearly in ... NASA Launches Twin Spacecraft to Solve the Mystery of Mars’ Lost Atmosphere

June 17, 2025 - Description The acquisition of the radio frequency signal from the Artemis II crewed mission to the Moon by NASA’s Deep Space Network (DSN) is indicated by the peak in the data signal shown on the top computer screen.

May 14, 2025 - Our space radiation miniseries discusses what causes space radiation, how space radiation affects the human body, how NASA protects astronauts, and more.

4 days ago - All the latest content about Nasa from the BBC.

Understanding the risk for developing ... to space radiation is also a high priority. “By using multiple research models, our team has identified only small changes in heart function and the tissue structure of heart and blood vessels,” said Marjan Boerma of the University of Arkansas, Little Rock, who has been an NSRL user for the past eight years. This would be good news for NASA if the risk ...

February 6, 2025 - The May 2024 solar storm created two extra radiation belts, sandwiched between the two permanent Van Allen Belts. One of the new belts, shown in purple, included a population of protons, giving it a unique composition that hadn’t been seen before.

August 1, 2024 - These are all components of space weather. When astronauts travel in space they can’t see or even feel radiation. However, NASA scientists are studying the effects radiation plays on the human body and developing ways to monitor and protect against this silent hazard.

November 20, 2024 - These measurements provide useful information for scientists trying to understand how solar radiation storms move through space and where their effects – and potential impacts on life beyond Earth – are most intense. NASA’s Solar Dynamics Observatory captured this image of a solar flare on May 11, 2024.

March 5, 2026 - Feb. 7, 2026 — Voyager 2’s flyby of Uranus in 1986 recorded radiation levels so extreme they baffled scientists for nearly 40 years.

... The fundamental building blocks for planet formation can exist even in environments with extreme ultraviolet radiation, according to a new study by an international collaboration led by Penn State astronomers.

2 days ago - And if an astronaut were ever caught outside their spacecraft during a solar event, the radiation could even be lethal. While the Apollo astronauts also ventured outside the magnetosphere and faced the same risks, the danger is heightened for the Artemis 2 crew: Their mission launched during one of the most active solar periods in recent history, at the height of the Sun’s 11-year cycle, making CMEs and flares more frequent. NASA is countering these risks on two fronts: physical shielding, and prediction and monitoring systems.

December 29, 2022 - WASHINGTON – NASA’s Van Allen Probes mission has discovered a previously unknown third radiation belt around Earth, revealing the existence of unexpected structures and processes within these hazardous regions of space. Previous observations of Earth’s Van Allen belts have long documented ...

February 26, 2024 - Nature - Scientists have identified a region in the Milky Way capable of accelerating particles to super-high energy levels.

2 days ago - The most important data from NASA’s first crewed Artemis II mission may not be its photographs, but the radiation measurements that will shape how humans work and survive beyond travel farther from Earth’s magnetic shelter safely.

June 24, 2021 - WASHINGTON — To protect astronauts from cancer-causing radiation in space, NASA should proceed with proposals to set a universal career-long radiation dose limit of ~600 millisieverts (mSv), says a new report from the National Academies of ...

July 31, 2024 - Scientists do not fully understand all the specific ways in which this ionizing radiation affects the human body. To learn more, NASA’s HRP created SRE.

Splashdown! Artemis 2 astronauts return to Earth after historic NASA mission to the moon NASA's Artemis 2 astronauts came home today (April 10), wrapping up an epic mission that broke spaceflight records and set the stage for even more ambitious moonshots to come.
