NASA has announced astronauts Christina Koch and Jessica Meir participated in a live news conference from orbit on Monday, Oct. 21, following the first spacewalk to be conducted by two women, NASA said.
The 30-minute news conference took place three days after the spacewalk, in which Koch and Meir replaced a faulty battery charger on the International Space Station´s truss structure, restoring power capabilities for station operations and ongoing research.
Koch and Meir replaced a battery charge/discharge unit (BCDU) that failed to activate following the Oct. 11 installation of new lithium-ion batteries on the station´s exterior structure.
Meir became the 15th US woman to spacewalk. Women have been performing spacewalks since 1984 — Russian cosmonaut Svetlana Savitskaya spacewalked that July, and NASA astronaut Kathryn Sullivan spacewalked in October that same year.
