Jessica Meir's first female spacewalk (left) and Christina Koch (right).
Summary
[edit]| Description |
Español: Las astronautas de la NASA Jessica Meir (izquierda) y Christina Koch (derecha) preparándose para salir de la escotilla de la Estación Espacial Internacional y comenzar la histórica primera caminata espacial femenina.
Las astronautas reemplazaron una unidad de descarga de carga de batería (BCDU) defectuosa que no se activó después de la instalación del 11 de octubre de nuevas baterías de iones de litio en la estructura exterior de la estación espacial. Las BCDU regulan la cantidad de carga puesta en las baterías que recolectan energía de los paneles solares de la estación hacia los sistemas de la estación de energía durante los períodos en que la estación orbita durante la noche alrededor de la Tierra. Aunque la falla de BCDU no ha afectado las operaciones de la estación o la seguridad de la tripulación, sí evita que las nuevas baterías proporcionen una mayor potencia de la estación.
English: NASA astronauts Jessica Meir (left) and Christina Koch (right) to prepare to leave the hatch of the International Space Station and begin the historic first-ever all-female spacewalk.
The astronauts replaced a faulty battery charge discharge unit (BCDU) that failed to activate following the Oct. 11 installation of new lithium ion batteries on the space station's exterior structure. The BCDUs regulate the amount of charge put into the batteries that collect energy from the station's solar arrays to power station systems during periods when the station orbits during nighttime passes around Earth. Though the BCDU failure has not impacted station operations or crew safety, it does prevent the new batteries from providing increased station power. |
