Space Tourism: Sustainable Apparel Herrada-Torres, Jose Santos; Castro-Gaona, Lizbeth Kely; Bonilla-Santiago, Jarim J.; Quintana-Garcia, Lynn A.; Duran-Aquino, Rivaldo Carlos In the era of space tourism, the sustainability and efficiency of astronaut clothing are crucial due to resource limitations and the environmental impact of transporting and disposing of materials. Models were reviewed in PubMed, Scopus, Google Scholar and Science Direct using the terms Smart textile, Wearable, Space Tourism, Space Exploration, Smart T-shirt. A two-layer smart T-shirt is proposed: inner layer (Astroskin) with sensors, antibacterial properties, and UV protection; outer layer made of cotton coated with CS/PDMS and PLA for self-cleaning

Enhancing Analog Space Missions With Neutral Position Body Angles: A Novel Approach to Simulating Microgravity Conditions on Earth Sanchez-Delgado, Wendy Lucia; Herrada-Torres, José Santos; Salazar-Reyes, Margarita; Escalante-Porlles, Angela Q'orianka; Montenegro-Arrasco, Dessiree Anghely; Huayanay-Flavio, Rosario Yulisa; Alvarez-Quichca, Jharold Axel; Duran-Aquino, Rivaldo Carlos Analog space missions are essential for preparing astronauts for the unique physical and psychological demands of space exploration. While current analog environments effectively simulate certain aspects of extraterrestrial habitats, reproducing the experience of microgravity on Earth remains a significant challenge. This paper explores the application of a "neutral position" body angle, a reclining posture at approximately 6 degrees, which redistributes bodily fluids and reduces joint stress in a manner that partially mimics microgravity effects

Female reproductive health in long-duration space missions: a narrative review of current challenges Herrada-Torres, José Santos; Castro-Gaona, Lizbeth Kely; Quintana-García, Lynn A.; Reyes-Lezama, Dayana Kelly; Vargas-Maucaylle, Magdalena Michely; Sanchez-Medina, Fabrizio Manuel; Perez-Velasquez, Jhareth Ariana; Mendoza Pariona, Angie Shirley Female reproductive health represents a critical dimension of long-duration spaceflight. This narrative review examined the impacts of space exposure, prolonged microgravity, cosmic radiation, and circadian rhythm disruption on female fertility and maternal-fetal health during space missions. A search was conducted in high-impact databases, and gray literature was also considered. The available evidence suggests that microgravity and radiation could suppress progesterone levels, reduce the ovarian reserve, or induce a nonreceptive endometrial phenotype

Potential distribution of the oncilla Leopardus tigrinus (Carnivora: Felidae) based on highresolution spatial data and camera traps in a national park in Peru Briceño, Nicole; Cano, Deyvis; Cámara, Frank; Campos, Bertha; Sandoval, Homer; Ricra, Alex; Rojas-Briceño, Nilton Potential species distribution models (SDMs) are typically evaluated over large territories via low-resolution spatial data and biased presence records. The Parque Nacional de Tingo María (National Park; PNTM, by their initials in Spanish), a small territory, presents challenges for this type of study. This study aimed to analyze the SDM of an oncilla (Leopardus tigrinus) and evaluate the most influential spatial data and specific distribution areas. The Maxent (Maximum Entropy) algorithm was used with 32 high-resolution spatial data layers derived from a PlanetScope multispectral satellite image, DEM, and bioclimatic, social, and infrastructure variables, resampled to 4.5 m resolution, along with 13 presence records from camera traps. The zones were overlaid to identify the species' habitat. The model has an AUC of 0.992, covering 54 hectares, favoring areas with the coldest quarter precipitation (Bio 19), dense vegetation (NDVI), and avoiding roadways and areas with lower elevations. The species is located in Buffer Zones (72.06%), Strict Protection Zones (3.93%), Recovery Zones (3.41%), Special Use Zones (0.54%), Tourist Zone I (10.66%), Tourist Zone II (0%), and Wilderness Zone (9.4%). The viability of the SDM in small spaces with precise, high-resolution data is highlighted. The current zoning of PNTM may not be sufficient to protect the critical habitats of most oncilla species.
