Space Weather at NASA Moon to Mars Office: Sun Activity, Carrington Event, and Artemis Missions

Overview

The podcast takes listeners inside NASA's Moon to Mars Space Weather Analysis Office to explore how space weather is monitored, analyzed, and used to protect astronauts and spacecraft across the solar system.

Key takeaways

• Space weather includes solar wind, sunspots, solar flares, and coronal mass ejections that affect Earth and space missions.
• The office emphasizes space weather analysis rather than official forecasts and collaborates with NOAA and other agencies.
• Historical Carrington events show how powerful solar storms disrupt technology and illuminate the risks of future activity.
• Artemis and future moon to Mars missions hinge on radiation monitoring, shielding, and real time decision making for crew safety.

Introduction to space weather

The podcast opens by defining space weather as a broad interaction between the Sun and planetary environments, including how solar activity can impact Earth and missions beyond our planet. It then moves behind the scenes to NASA's Moon to Mars Space Weather Analysis Office, a team tasked with monitoring the Sun and its emissions, not as forecasters but as analysts who forecast potential impacts and inform mission operators across NASA and partner agencies.

Meet the team and daily workflow

The episode introduces space weather analysts Hannah Herman and Karina Alden, along with Tony Iampetro who leads the daily briefing. The office environment is described as a classroom like space with whiteboards, charts, and a friendly leaderboard tracking solar flare events. A typical day involves continuous observation from 8 am to 4 pm and on call coverage after hours. Every day at 10 am a briefing gathers scientists from across NASA to review solar activity data from spacecraft such as SOHO and the Solar Dynamics Observatory. The team uses a range of data streams including electron flux, proton flux, and X ray flux to assess potential space weather events that could affect missions either near Earth or out in deep space.

Space weather phenomena and how they are studied

The podcast explains core phenomena including solar wind, sunspots, solar flares, and coronal mass ejections. Flares are described as sudden energy releases from the sun, while CMEs are huge eruptions of magnetized plasma that can interact with Earth’s magnetosphere and create geomagnetic storms. The host notes that space weather is a 360 degree phenomenon, so NASA monitors emissions from all directions to understand potential impacts on missions across the solar system. The analysts connect data from multiple observatories and discuss how radiation levels influence spacecraft systems and crew safety during missions beyond Earth’s protective magnetic field.

Historical lessons: the Carrington Event and beyond

The narrative then revisits the Carrington event of 1859, a solar flare so bright it illuminated the entire night sky and sparked auroras visible in tropical regions. The event is tied to a subsequent CME that reached Earth quickly and disrupted telegraph networks, illustrating the dramatic effects of intense solar activity. The discussion also references 1989 and 2003 space weather events that caused power grid disturbances and damage to satellites, underscoring the ongoing importance of monitoring and preparedness for modern infrastructure and spaceflight.

Space weather and human spaceflight

A central theme is the radiation risks faced by astronauts venturing beyond Earth’s magnetosphere. The Space Weather Analysis Office collaborates with NASA's Space Radiation Analysis Group to monitor radiation levels and advise shielding strategies. Artemis program plans are highlighted as proving grounds for 247 day and night monitoring, with Artemis I having tested radiation detectors using mannequins as stand-ins for astronauts. The episode emphasizes that protecting humans on long duration missions to the Moon and Mars requires advanced monitoring, shielding, and real time decision making about activities such as spacewalks.

Artemis and the Moon to Mars pin

The host explains the Moon to Mars concept and notes Artemis I as a pivotal rehearsal for Artemis II and future crewed missions. The Space Weather Office is described as preparing for round the clock coverage during Artemis missions, with real time analysis guiding mission control decisions and astronaut safety considerations.

Public engagement and curiosity

The show closes this segment with a listener question from Lizzie Peabody of side Door about predicting solar flares. The discussion covers how corona dynamics observed during eclipses can offer clues about flare precursors and mentions research using Solar Dynamics Observatory data to build models that may improve flare predictions over time. The exchange demonstrates how public curiosity informs and enriches space science communication.

Credits and takeaway

The episode credits NASA, the Moon to Mars Space Weather Analysis Office, NOAA, and the heliophysics community and ends with an invitation to engage through reviews and social platforms, emphasizing the collaborative, credible, AI-enhanced approach to trusted STEM content.
