A SpaceX Dragon mission to deliver 6,500 pounds of cargo to the International Space Station was postponed for the second time on Wednesday night because of weather conditions at Cape Canaveral Space Force Station. The launch was called off about 30 seconds into the countdown, marking the second delay for the mission. The next opportunity for liftoff is set for 6:05 p.m. ET Friday. The mission, part of NASA’s SpaceX CRS-33 contract, had previously been postponed on Tuesday for similar reasons. The spacecraft is expected to carry water purification hardware and research equipment aimed at studying space weather and osteoporosis treatments. The Dragon will take about 38 hours to reach the space station, where it will remain until mid-June before splashing down off California’s coast. NASA officials said the mission will also include experiments on charged particles around Earth and their impact on power grids. The launch will be streamed live on NASA+, Amazon Prime, and the NASA YouTube channel, along with official social media accounts. Bill Spetch, a NASA operations manager, highlighted the mission’s focus during a Monday teleconference, noting the importance of the research for both space and Earth-based applications. As of Tuesday, seven astronauts were aboard the ISS, including three Americans, three Russians, and French astronaut Sophie Adenot.
