SpaceX launched yet another batch of its Starlink internet satellites to orbit today (Sept. 20), sending the spacecraft aloft from Vandenberg Space Force Base in California.

The Falcon 9 rocket is slated to lift off at exactly 7:20 a.m. from the SLC-4E launch site at Vandenberg Space Force Base. This mission, dubbed Starlink 9-17, marks another significant step in SpaceX’s efforts to expand its satellite internet connectivity.

Satellite swarms orbiting the Earth are leaking more radiation into protected wavelength bands than ever. In fact, the second generation of Starlink satellites – known as the v2mini and v2mini Direct-to-Cell versions – are leaking up to 32 times more radiation than their predecessor.
