News Release, NASA
NASA astronauts Christina Koch and Jessica Meir will venture outside the space station at 7:50 a.m. Thursday, Oct. 17 or Friday, Oct. 18. Live coverage will begin at 6:30 a.m. on NASA Television and the agency’s website.
Space station managers have postponed three spacewalks previously scheduled for this and next week to install new batteries in order to first replace a faulty battery charge/discharge unit (BCDU). The BCDU failed to activate following the Oct. 11 installation of new lithium-ion batteries on the space station’s truss. The three spacewalks previously planned to continue the installation of additional lithium-ion batteries will be rescheduled.
The BCDU failure has not impacted station operations, the safety of the crew, or the ongoing experiments aboard the orbiting laboratory, many in preparation for future human missions to the Moon and Mars. The station’s overall power supply, which is fed by four sets of batteries and solar arrays, remains sufficient for all operations. However, the faulty power unit does prevent a set of batteries installed earlier this month from providing increased station power.
The BCDU’s regulates 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 a nighttime pass around Earth. Two other charge/discharge units on the affected 2B power channel did activate as planned and are providing power to station systems.
This will be Koch’s fourth spacewalk and Meir’s first. Watch video of the two discussing the possibility of conducting a spacewalk together at:
The Southern Maryland Chronicle is a local, small business entrusted to provide factual, unbiased reporting to the Southern Maryland Community. While we look to local businesses for advertising, we hope to keep that cost as low as possible in order to attract even the smallest of local businesses and help them get out to the public. We must also be able to pay employees(part-time and full-time), along with equipment, and website related things. We never want to make the Chronicle a “pay-wall” style news site.
To that end, we are looking to the community to offer donations. Whether it’s a one-time donation or you set up a reoccurring monthly donation. It is all appreciated. All donations at this time will be going to furthering the Chronicle through hiring individuals that have the same goals of providing fair, and unbiased news to the community. For now, donations will be going to a business PayPal account I have set-up for the Southern Maryland Chronicle, KDC Designs. All business transactions currently occur within this PayPal account. If you have any questions regarding this you can email me at firstname.lastname@example.org
Thank you for all of your support and I hope to continue bringing Southern Maryland the best news possible for a very long time. — David M. Higgins II
