#NASA says the #Artemis II crew can ... move equipment 🛍️ around within the capsule to effectively thicken its walls in the direction from which the #SolarStorm is coming

Sometimes such flares
️ are accompanied by outbursts of high-energy radiation 
️ particles, which can travel near the speed of light and would easily penetrate space vehicle shielding 
️. High energy #radiation particles can be a cause of malfunctions in computers and electronics, and they also pose #health risks for #astronauts 🧑

#SpaceWeather : The chance for strong flares
️ increased to 20%. The main driver is active region #AR4405Forecast:
April 1: A #CME may provoke enhancements up to G2 (moderate) geomagnetic storming late today April 2: G1 (minor) #geomagnetic storm levels expected April 3: Unsettled to active conditions may occur. A chance of G1 (minor) storm intervals exists if the next coronal hole’s fast solar wind stream arrives earlier than expected -

, the mission’s trajectory is designed to bring it back to Earth even if Orion hits a snag.Artemis I : During Orion’s return through Earth’s atmosphere, material from the capsule’s heatshield had broken off in chunks. There was a similarly problematic heatshield already installed on the crew capsule for Artemis II https://www.planetary.org/articles/whats-keeping-the-artemis-astronauts-safe

️ activity jumped to moderate over the past day, with 24 total flares. Three of them were M, or moderate flares, and one was edging up toward being an X flareForecast:
April 4 we might get more G1-G2 (minor-moderate) #geomagnetic storms April 5 possibly with more G1 enhancements April 6 unsettled-to-active conditions as effects from the solar wind stream and #CME start to subside -
