As the Artemis 2 mission prepares to send astronauts to the moon for the first time since the Apollo era, NASA and NOAA are closely monitoring space weather conditions to ensure the safety of the crew. With the sun's activity trending down from its peak, the risk of solar radiation storms remains a concern, and the two agencies are working together to provide real-time forecasting and decision support during the mission.

Why it matters

The Artemis 2 mission marks a significant milestone in space exploration, but venturing beyond Earth's protective atmosphere and magnetic field exposes the astronauts to the hazards of space weather, including solar flares, coronal mass ejections, and cosmic rays. Accurate forecasting and mitigation strategies are crucial to the success and safety of the mission.

The details

NOAA's Space Weather Prediction Center (SWPC) will have forecasters embedded at NASA's Johnson Space Center, working alongside experts from the Space Radiation & Analyses Group (SRAG). They will utilize an array of consensus-building space weather modeling tools, similar to hurricane forecasting, to monitor the mission and provide timely updates. While the current solar maximum phase is trending down, the potential for sudden solar radiation storms remains a concern that the teams are prepared to address.

  • The Artemis 2 mission is set to launch in April 2026.
  • A testbed exercise held in 2025 aimed to strengthen collaboration and evaluate space weather products.

What they’re saying

“We must not let individuals continue to damage private property in San Francisco.”

— Robert Jenkins, San Francisco resident

“Fifty years is such an accomplishment in San Francisco, especially with the way the city has changed over the years.”

— Gordon Edgar, grocery employee

What’s next

The SWPC and NASA teams will continue to monitor the sun's activity and provide real-time updates and decision support throughout the Artemis 2 mission, ensuring the safety of the astronauts as they venture to the moon and back.

The takeaway

The collaboration between NOAA, NASA, and other organizations is crucial in ensuring the safety of the Artemis 2 astronauts and the success of the mission. While space weather remains a significant challenge, the teams are well-prepared to mitigate the risks and provide the necessary support to enable this historic lunar voyage.
