Webb moved for fueling #shorts 06-12-2021 06:44 PM CET
The James Webb Space Telescope, configured for flight, was moved from the cleanroom to the payload preparation facility for fuelling at Europe’s Spaceport in French Guiana on 11–12 November 2021. Webb will be loaded with propellants before being mounted on top of the rocket and then encapsulated by the Ariane 5 fairing. Webb will be the largest, most powerful telescope ever launched into space. As part of an international collaboration agreement, ESA is providing the telescope’s launch service using the Ariane 5 launch vehicle. Working with partners, ESA was responsible for the development and qualification of Ariane 5 adaptations for the Webb mission and for the procurement of the launch service by Arianespace. Webb is an international partnership between @NASA , ESA and the @Canadian Space Agency.

The James Webb Space Telescope was fuelled inside the payload preparation facility at Europe’s Spaceport in French Guiana ahead of its launch on Ariane 5.

Webb’s thrusters will use this propellant to make critical course-corrections after separation from Ariane 5, to maintain its prescribed orbit about one and a half million kilometres from Earth, and to repoint the observatory and manage its momentum during operations.

Fuelling any satellite is a particularly delicate operation requiring setup of the equipment and connections, fuelling, and then pressurisation.

Webb’s propellant tanks were filled separately with 79.5 l of dinitrogen tetroxide oxidiser and 159 l hydrazine. Oxidiser improves the burn efficiency of the hydrazine fuel.

These propellants are extremely toxic so only a few specialists wearing Self-Contained Atmospheric Protective Ensemble, or ‘scape’ suits, remained in the dedicated fuelling hall for fuelling which took 10 days and ended on 3 December.

The next steps will start soon for ‘combined operations’. This is when specialists working separately to prepare Webb and Ariane 5 will come together as one team. They will place Webb atop its Ariane 5 launch vehicle and encapsulate it inside Ariane 5’s fairing.

Then, no longer visible, Webb, joined with its Ariane 5 launch vehicle will be transferred to the Final Assembly building for the final preparations before launch.

Webb will be the largest, most powerful telescope ever launched into space. As part of an international collaboration agreement, ESA is providing the telescope’s launch service using the Ariane 5 launch vehicle. Working with partners, ESA was responsible for the development and qualification of Ariane 5 adaptations for the Webb mission and for the procurement of the launch service by Arianespace.

Webb is an international partnership between NASA, ESA and the Canadian Space Agency (CSA).

Europe’s largest satellite constellation has grown even bigger, following the launch of two more Galileo navigation satellites by Soyuz launcher from Europe’s Spaceport in French Guiana on 5 December. Galileo satellites 27-28 add to an existing 26-satellite constellation in orbit, providing the world’s most precise satnav positioning to more than 2.3 billion users around the globe.

Soyuz launcher VS-26, operated by Arianespace and commissioned by ESA, lifted off with the pair of 715 kg satellites from French Guiana on 5 December at 01:19 CET. All the Soyuz stages performed as planned, with the Fregat upper stage releasing the satellites into their target orbit close to 23 525 km altitude, around 3 hours and 54 minutes after liftoff.

The satellites will spend the coming weeks being manoeuvred into their final working orbit at 23 222 km using their onboard thrusters, at the same time as their onboard systems are gradually checked out for operational use – known as the Launch and Early Operations Phase.
