SpaceX Launches Upgraded Starlink Satellites in Successful Mission.

SpaceX is set to launch its second batch of upgraded Starlink satellites on April 19 using a Falcon 9 rocket. The 21 satellites will be part of the v2 Mini design, which is smaller than the original plan due to issues with the technology. Despite being smaller, the v2 Mini variants still contain the majority of the upgrades that will fly on the standard v2 satellites. The satellites will eventually operate in circular orbits with altitudes of 525, 530, and 535 km and inclinations of 53, 43, and 33 degrees, respectively, using frequencies in the Ku- and Ka-band.
