Launch of Start-1M Rocket from Vostochny Spaceport Delayed Until 2027

• April 8, 2026

The first flight of the Start-1M launch vehicle from Russia’s Vostochny Cosmodrome has been rescheduled for 2027, according to statements from Roscosmos officials. Initially anticipated sooner, the launch delay stems from the need to conduct further ground testing to ensure the reliability of the new converted rocket.

Additional Testing to Ensure Reliability

Alexander Davydov, head of the reusable launch systems department at Roscosmos, explained that extra ground-based evaluations are crucial for enhancing the dependability of the Start-1M, a launcher developed through the conversion of existing missile technology. These tests are intended to identify and mitigate potential issues before the rocket’s maiden flight, reflecting a cautious approach toward integrating converted hardware into operational space missions.

The launch vehicle is part of Russia’s ongoing efforts to develop reliable and cost-effective space access solutions utilizing converted missile systems. The Vostochny Cosmodrome, Russia’s newest spaceport, will serve as the site for the first bolt from this updated rocket. Delays in launch timelines are common in aerospace projects, as mission success hinges heavily on rigorous validation processes.

This postponement signifies careful prioritization of mission safety and vehicle reliability over adhering to an earlier schedule. While further specifics on the technical nature of the additional testing have not been provided, the emphasis on enhancing confidence in the Start-1M’s performance hints at a comprehensive validation campaign.

The delay has broader implications for Russia’s space launch cadence, especially for projects that depend on the Start-1M vehicle’s capabilities. However, ensuring thorough examination before committing to flight operations aims to reduce risks associated with early launches, potentially averting failures that could impact future missions and infrastructure at the new spaceport.

Additional details, including the revised schedule beyond the 2027 timeline and the overall program roadmap for Start-1M, remain forthcoming as Roscosmos continues to refine development and testing phases.

The inaugural launch of the Start-1M launch vehicle from Russia’s Vostochny Cosmodrome has been postponed to 2027 due to additional ground testing requirements.
