Telemetry from the James Webb Space Telescope has successfully been received at the Jupiter Control Center at Europe’s Spaceport in French Guiana.
A little more than two minutes after launch, the two solid rocket boosters on the Ariane 5 separated from the vehicle and then fell back into the ocean. Next, the fairing — which was modified with additional venting ports to allow for smooth depressurization of the fairing from ground pressure to vacuum during the flight—was jettisoned, exposing Webb to space for the first time. The S-Band Transmitter has now been powered on and is confirmed as transmitting telemetry.
