Russia’s Soyuz ST-A rocket has launched with the European Space Agency’s Sentinel-1B spacecraft and four small satellites, following three delays – two relating to unacceptable weather for both Friday and Saturday’s attempts and then a technical scrub on Sunday. In what was the rocket’s first launch of the year from its South American launch site, liftoff occurred at 18:02:13 local time (21:02 UTC) on Monday.
