Proton-M Launch Delayed for Repairs, Space Mission Unaffected

The scheduled launch of a Proton-M rocket has been postponed following the detection of a minor discrepancy within its upper stage during routine pre-launch checks. Roscosmos officials stated that the issue has been identified and that corrective measures are already underway.

Despite this postponement, the space agency assured that the overall scientific program and mission objectives will not be affected. Preparations for the rocket's launch will resume in a normal mode once the necessary adjustments are completed.

The mission involves the Electro-L satellite, which plays a critical role in collecting vital hydrometeorological data and multispectral imagery of Earth from its geostationary orbit. Existing Electro-L satellites launched in previous years continue to function effectively.
