Three crew members are safe after an automatic abort halted their scheduled launch to the International Space Station from the Baikonur Cosmodrome in Kazakhstan. The crew, consisting of NASA astronaut Tracy C. Dyson, Roscosmos cosmonaut Oleg Novitskiy, and spaceflight participant Marina Vasilevskaya of Belarus, were expected to lift off aboard a Roscosmos Soyuz MS-25 spacecraft.
Twenty seconds before the planned launch time, an automatic abort was triggered due to a failure of the second umbilical, or service tower, to initiate an engine sequence start on the Soyuz rocket. The reason for this failure is currently unknown, as stated in a NASA broadcast of the launch.
