SpaceX postpones a highly anticipated test launch of its upgraded Starship megarocket, after multiple countdown stops and restarts. The company calls off the test scheduled for Thursday, with SpaceX engineers citing delays during the countdown process. The postponement follows amid heightened attention on SpaceX’s plans for a major financial move, including announcements about a record-breaking stock market debut. BBC reports that the setback comes shortly after SpaceX revealed plans for an IPO. Other outlets similarly describe the timing as high-stakes, linking the renewed focus on Starship testing with the company’s broader timeline toward an IPO. No agreed-upon new launch date is stated in the provided reports. The decision reflects the company’s ongoing emphasis on test outcomes and safety checks during high-profile flight preparations, while the specific cause of each countdown interruption is not detailed in the available summaries.
