    Lunar and Martian gravity alter immune cell interactions with endothelia in parabolic flight by Yu Du, Bing Han, Katharina Biere, Nathalie Abdelmalek, Xinyu Shu, Chaoyang Song, Guangyao Chen, Ning Li, Marina Tuschen, Huan Wu, Shujin Sun, Alexander Choukér, Mian Long, Dominique Moser

    Published 2025-02-01
    “…Comparable to microgravity, partial gravity in these destinations is assumed to dysregulate immune functions, thereby threatening astronauts´ health. To investigate the impact of partial gravity on immune cell attachment to vessel endothelia, THP-1 cells and HUVEC cell layers were monitored in a flow chamber system during parabolic flight in lunar (0.16 g) or Martian (0.38 g) gravity. …”

    Galactic Cosmic Radiation in the Interplanetary Space Through a Modern Secular Minimum by F. Rahmanifard, W. C. deWet, N. A. Schwadron, M. J. Owens, A. P. Jordan, J. K. Wilson, C. J. Joyce, H. E. Spence, C. W. Smith, L. W. Townsend

    Published 2020-09-01
    “…We used these results to determine the most conservative permissible mission duration (PMD, 290.4−35.9+37.7 and 204.3−25.2+26.6 days for 45‐year‐old male and female astronauts, respectively) based on a 3% risk of exposure‐induced death (REID) at the upper 95% confidence interval in interplanetary space.…”

    Forecasting High‐Speed Solar Wind Streams From Solar Images by Daniel Collin, Yuri Shprits, Stefan J. Hofmeister, Stefano Bianco, Guillermo Gallego

    Published 2025-01-01
    “…Abstract The solar wind, a stream of charged particles originating from the Sun and transcending interplanetary space, poses risks to technology and astronauts. In this work, we develop a prediction model to forecast the solar wind speed (SWS) at the Earth. …”
