SN4 becomes first full-scale Starship prototype to pass cryogenic proof test

SN4 follows the Mk1, SN1, and SN3 full-scale Starship prototypes. The previous full-scale builds all failed cryogenic proof testing. The cryogenic proof is when the Starship is filled with liquid nitrogen to verify that its tanks can withstand flight pressures.

See a string of lights in the sky? It was probably SpaceX’s ‘Starlink’ satellites

The 60 Starlink broadband satellites rode atop one of SpaceX’s Falcon 9 rockets, taking off from Florida’s Kennedy Space Center at 3:30 pm ET. The devices are now coasting through orbit, where they will soon begin climbing to about 340 miles above ground, their operational altitude. This launch brings the total number of Starlink satellites in orbit to more than 400.

The company plans to eventually grow its constellation to more than 40,000 satellites, blanketing the entire planet in cheap, high-speed Internet connectivity.
