SpaceX scrubbed the launch from Florida of a four-man crew heading to the International Space Station early Monday with less than three minutes remaining in the countdown, delaying the start of a six-month mission to examine a problem with a ground system needed to ignite the Falcon 9 rocket’s main engines.
SpaceX called off the launch a Falcon 9 rocket and Crew Dragon spacecraft at 1:45 a.m. EST (0645 GMT) from NASA’s Kennedy Space Center in Florida to evaluate an issue with the system used to ignite the rocket’s main engines. When it takes off, the mission will send two NASA astronauts, an Emirati astronaut, and a Russian cosmonaut on a six-month mission on the International Space Station.
Led by a three-time space shuttle flier and former Navy submarine officer, the four-man team set to ride into orbit Monday on SpaceX’s Dragon Endeavour spacecraft rode to the launch pad in Florida in new black Tesla Model Xs and took their seats inside the commercial crew capsule Thursday night for a countdown dress rehearsal.
Two months after a coolant leak disabled a Soyuz crew ferry spacecraft at the International Space Station, Russia’s space agency launched of a replacement vehicle from the Baikonur Cosmodrome in Kazakhstan Thursday, and the craft docked at the station at 7:58 p.m. EST Saturday (0058 GMT Sunday). The Soyuz MS-23 spacecraft launched without any people on-board, and will serve as a lifeboat and ride home for a three-man space station crew later this year.
