Crucial Products for A Successful Launch
During assembly and before the JWST finally launches on board an Ariane 5 rocket, a rotating and tilting device developed and produced by Beyond Gravity in Vienna, enables engineers to work on the telescope from all sides. Depending on the requirements, the trolley moves the telescope to a vertical or horizontal position. Beyond Gravity has already delivered more than 80 so-called "multipurpose trolleys," which can rotate and tilt a satellite, to customers in Europe and the United States.
The top of the Ariane 5 rocket is made of Beyond Gravity’s payload fairing. It protects the JWST during liftoff and its journey through the atmosphere. The 17-meter-high structure was produced at the company’s site in Emmen, Switzerland. The Webb’s sunshield – as big as a tennis court – was specially engineered to fold up and fit within the 5.4-meter diameter fairing. The Beyond Gravity fairing was custom-made for this precious payload. New hardware ensures that venting ports around the base of the fairing remain fully open. This will minimize the shock of depressurization when the fairing is jettisoned away from the launch vehicle.
On its way into space, the launch vehicle is controlled by a Beyond Gravity on-board computer ("brain"). Once the payload reaches a certain height, the two halves of the payload fairing are separated and jettisoned from the launch vehicle. The corresponding separation system was manufactured by Beyond Gravity in Linköping, Sweden. At a later stage, this separation system (payload adapter) allows the JWST to be separated from the launch vehicle.
