The first woman to conduct a spacewalk was Russian cosmonaut Svetlana Savitskaya in 1984, followed closely by NASA astronaut Kathy Sullivan. An additional 12 US women have conducted 40 spacewalks over the past 35 years. Koch and Meir will be 13th and 14th, respectively.Koch and Meir spoke about women working in human spaceflight during a recent news conference."I think it's important because of the historical nature of what we're doing and that in the past, women haven't always been at the table," Koch said. "It's wonderful to be contributing to human spaceflight at a time when all contributions are being accepted, when everyone has a role and that can lead, in turn, to increased chance for success."There are a lot of people that derive motivation from inspiring stories from people that look like them and I think it's an important aspect of the story to tell," Koch said."What we're doing now shows all the work that went in for the decades prior, all of the women that worked to get us where we are today," Meir added. "I think the nice thing for us is we don't even really think about it on a daily basis, it's just normal. We're part of the team, we're doing this work as an efficient team working together with everybody else, so it's really nice to see how far that we've come."Meir tweeted about preparing for the walk."Gearing up for Friday's spacewalk to help the ground teams repair one of the battery channels with @Astro_Christina. . . . first spacesuit selfie, check! Photos will be much more spectacular once we pass through the hatch. Be sure to watch live: https://nasa.gov/live"Koch and Meir will be replacing a faulty battery charge/discharge unit that failed to activate after a spacewalk October 11, according to the agency. Because the unit is faltering, it's keeping newly installed batteries from providing an increase in power to the station.The space station is powered by solar arrays and four sets of batteries. Luckily, the faulty unit hasn't changed anything for the astronauts or experiments on board. The unit regulates the charge in the batteries from the solar arrays as the station orbits at night around the Earth.Once the unit is replaced, postponed spacewalks to replace the batteries can be rescheduled.Although floating in space looks easy, astronauts say that spacewalks are one of the most physically challenging things they can do, according to NASA.This is the second attempt at an all-female spacewalk after the first was scrapped in March.For the intended spacewalk in March, Koch was going to be paired with astronaut Anne McClain, who has since returned to Earth. In March, NASA cited 2643

The news that Turkey could enter the consulate comes a day after Saudi King Salman called Turkish President Recep Tayyip Erdogan to discuss the Khashoggi case.On Sunday, the two leaders agreed on a joint working group to look into the journalist's disappearance -- three days after a similar announcement regarding the formation of a working group.On Saturday, Turkish Foreign Minister Mevlut Cavusoglu said Saudi Arabia "must cooperate" and allow the chief prosecutor's office and experts to search the premises.Turkish investigators are pushing for complete access for forensic teams to enter the consulate and the nearby consul general's residence, according to Turkish media reports. It was unclear whether the Saudis would allow the comprehensive search at both premises that the Turks have requested permission to carry out.Turkish authorities believe 15 Saudi men who arrived in Istanbul on October 2 were connected to Khashoggi's disappearance and possible murder. At least some of them appear to have high-level connections in the Saudi government.On Friday, a source familiar with the ongoing investigation told CNN that Turkish authorities have audio and visual evidence that Khashoggi was killed inside the consulate.His fiancée, Hatice Cengiz, who was waiting outside the consulate, says she did not see him re-emerge. 1331

This has been largely debunked by the scientific community," Lindenberger said in a 475
