NASA Astronauts Bob Behnken, Chris Cassidy begin Spacewalk outside ISS, watch video

Few weeks after the historic launch of SpaceX Crew Dragon that carried Bob Behnken and Doug Hurley to the International Space Station (ISS), Behnken and ISS astronaut Chris Cassidy have started the “spacewalk” on June 26. Among many milestones for the hours-long walk that is underway, the latest update posted by NASA and the ISS said that first of the three ageing nickel-hydrogen batteries have been replaced. The pistol grip tool or PGT was being used to “complete” the release of the boats and the second replacement was initiated. The first nickel-hydrogen battery was released and @Astro_SEAL and @AstroBehnken worked together to move it to the external pallet for disposal. Now they will install the first new battery. https://t.co/cBNqC5JGaz pic.twitter.com/V5ZiEFkHT3 — Intl.

Moreover, the astronauts will be installing an "adapter plate" to finish the circuit to the newly replaced batteries and relocating the nickel-hydrogen batteries, two of them have to be moved to an external platform for future disposal. NASA has also predicted for the walk to last for at least seven hours. Another similar venture is planned for July 1. On June 26, both Cassidy and Behnken will replace all batteries to upgrade the power supply capabilities Watch spacewalk live coverage: Today’s spacewalk is underway!👨🚀👨🚀 At 7:32am ET @AstroBehnken & @Astro_SEAL set their spacesuits to battery power, marking the beginning of a spacewalk that could last as long as seven hours.
