Four astronauts are preparing to fly around the Moon on a roughly 10-day mission, and for the entire trip, teams on the ground will be watching the Sun as closely as they watch the spacecraft. NASA and NOAA plan to provide continuous space-weather monitoring and decision support during Artemis II,

Citizen scientists reviewing NASA data discovered unusually high Solar flare rates, helping researchers better understand the Sun’s magnetic activity and improve space-weather predictions.

NASA’s Parker Solar Probe completed its 27th close approach to the Sun on March 11, again matching its record distance of 3.8 million miles (6.2 million kilometers) from the solar surface.

With the Artemis II mission launching its astronauts outside Earth's magnetic field for the first time on 1 April 2026 in over 50 years, NASA is setti.

NASA outlines how Artemis II astronauts are monitored for solar particle events during their lunar mission, including spacecraft shielding, real-time tracking, and onboard radiation detection systems.

The sun’s activity is escalating far beyond scientist’s predictions, Nasa has warned, resulting in more solar storms, flares and space weather events. Solar activity typically follows an 11-year cycle, with the cycle’s strength steadily decreasing ...
