Comparison of Solar Energetic Particle Flux Measurements by CRaTER and GOES

open access: yesSpace Weather, Volume 23, Issue 4, April 2025.
Abstract The Cosmic Ray Telescope for the Effects of Radiation (CRaTER) aboard the Lunar Reconnaissance Orbiter spacecraft has been operating in lunar orbit since 2009. CRaTER data provide a long‐term record of the near‐Moon radiation environment that is relevant to human exploration.

Nowcasting Solar Energetic Particle Events for Mars Missions

open access: yesSpace Weather, Volume 23, Issue 4, April 2025.
Abstract In addition to the omnipresent Galactic Cosmic Rays, sudden Solar Energetic Particle (SEP) events present considerable health hazards for manned space missions. These events not only contribute to an increased long‐term cancer risk, but can, in extreme cases, cause acute radiation syndromes.

Review of asteroid, meteor, and meteorite‐type links

open access: yesMeteoritics &Planetary Science, Volume 60, Issue 4, Page 928-973, April 2025.
Abstract With the goal to determine the origin of our meteorites in the asteroid belt, video and photographic observations of meteors have now tracked 75 meteorite falls. Six years ago, there were just hints that different meteorite types arrived on different orbits, but now, the number of orbits (N) is high enough for distinct patterns to emerge.
